China is attempting a precarious balancing act Expert comment NCapeling 9 March 2023

In its efforts to maintain ties with both Russia and Europe, China is having to wade through conflicting interests and rapidly changing sentiments.

Precisely how far China will go in supporting Russia has been one of the most important questions of the war in Ukraine.

On 20 February, US secretary of state Antony Blinken warned China may soon provide arms (‘lethal support’) to Moscow. But then, on 24 February – the anniversary of Russia’s invasion – China released a position paper calling for a political settlement to end the conflict, tellingly omitting any mention of its ‘no-limits partnership’ with Russia.

China’s goal was to present itself as a neutral mediator. In fact, Beijing’s ties with Russia remain unchanged, even if this relationship has grown more exasperating for Chinese diplomats over the past year.

Their job is to continue striking a delicate balance, a task that is becoming increasingly difficult as Russian president Vladimir Putin doubles down on nuclear brinkmanship and reckless rhetoric.

Staying out of the Ukraine war

With Putin extolling the law of the jungle in its most brutal form, China must be careful not to involve itself too much in the conflict. After all, Russia is clearly losing, and China has high hopes of repairing ties with major European economies.

But Putin is of course keen to signal that China has his back. That is why he recently rolled out the red carpet for China’s top diplomat Wang Yi and then alluded to an (unconfirmed) upcoming visit by Chinese president Xi Jinping.

Such diplomatic developments allow him to present China’s ambivalent position as, in fact, an endorsement of the invasion. While the costs of aligning with Russia could easily outweigh the benefits for China, one must remember that China’s reasons for maintaining good relations with the Kremlin go beyond the war in Ukraine.

For starters, the two countries share a 2,672-mile (4,300-kilometer) border – roughly equivalent to the width of Europe – and the frontier’s exact location was not even finally settled until the beginning of this century, after generations of negotiations that included some 2,000 meetings.

Yet to this day, the spectre of the Sino-Soviet split in the 1950s and 1960s looms large on both sides and it is not likely to be exorcised anytime soon. With China focused on moves by the US and its allies in East Asia and the Indo-Pacific, it simply cannot afford sabre-rattling or unrest on its other borders.

Moreover, unlike the collective West, China’s foreign policy has always been shaped by interests rather than by values. Even with respect to Russia, the two countries’ bond is based mainly on shared resentment of US hegemony. By deepening their bilateral cooperation in recent years, they have been able to achieve a level of great-power status with which to counterbalance America.

But Putin’s misadventure in Ukraine has forced Xi and China’s newly minted Politburo to manage a new set of economic, financial, and political risks.

Russia’s war has left the West more firmly united than it has been in years. As China’s relations with the US have reached new lows, Chinese leaders want to avoid also alienating the European Union (EU), which is one of the country’s biggest trading partners.

This is why Xi and Chinese diplomats have been so careful not to accept the Kremlin’s talking points in full. Being isolated from the ‘collective West’ is not an attractive option for China, given its hopes of achieving a robust economic rebound after years of the zero-COVID policy.

Balancing Europe with the Global South

In seeking to keep diplomatic and trade channels open, China’s main tactic has been to reassure European countries that it will use its own ties with Russia to restrain Putin from deploying nuclear weapons.

At the same time, China is making a renewed push to strengthen its ties with the Global South where many countries do not see the war in Ukraine in the same stark moral terms as the West does.

The emphasis on energy and food security in China’s recent position paper may have struck a chord with developing countries that have been reeling from the war’s negative knock-on effects on their economies.

Beijing briefing: China aims for tech self-reliance The World Today mhiggins.drupal 28 March 2023

Xi Jinping’s new appointments are tasked with a technology led recovery, but they face a daunting task to restore growth, writes Yu Jie.

The three-day state visit to Moscow by President Xi Jinping in March may have eclipsed the National People’s Congress in Beijing a fortnight earlier, but as Xi seeks to establish a new global order with China at its centre, the political events in the Great Hall of People provide an important insight into the country’s longer-term economic plans.

While a new cohort of cabinet members was appointed to sit on the State Council for the next five years, much of the attention remains on China’s economic stimulus plan to enable a rapid post-Covid recovery, as well as proposals to restructure central government.

Mountainous task

Three aspects of this year’s Congress deserve deeper scrutiny: Li Qiang’s confirmation as premier to succeed Li Keqiang’s decade-long subdued tenure under Xi; the extent to which Xi’s new cabinet sheds light on China’s economic and scientific self-reliance; and the unveiling of a major restructuring of central government administration in sectors such as finance and science.

China’s new premier initially faces the mountainous task of restoring growth and market confidence. During a press conference much shorter than his predecessor would hold, Li Qiang praised China’s private business sector and repeated the words ‘China remains open to foreign business’ to address the growing anxieties among foreigners and Chinese private entrepreneurs.

Beside the daunting task of economic recovery, Li Qiang faces another big challenge. Unlike his predecessors, he has never worked as a vice premier and overseen ministries under the State Council. The test for him will be to pursue a sound economic recovery plan while coordinating numerous central government agencies. He will also need to regulate relations among provincial heads who have a tendency to argue endlessly over the distribution of public finances.

Even though Xi is secure in his third term, his involvement in shaping and implementing macro-economic policies is keenly felt. Li Qiang made explicit the State Council under his leadership will be the chief implementor of all policies approved by the president. This is a less equal working partnership with Xi than his predecessors on the State Council enjoyed in the past.

Beijing published its official plan to restructure its central government administration announcing planned cuts of 5 per cent of its civil service. The newly established Central Commission on Finance intends to deal with systemic financial risks and to coordinate the financial regulatory bodies, central bank and Ministry of Finance. This is seen to reflect the Chinese leadership’s growing concern with the poor performance of local government loans and debt as well of the volatility of the property market, all of which threaten huge uncertainty for the economy.

As well as reorganizing the financial sector, Xi’s intention to pursue an integrated national strategy combining economic and scientific self-reliance has led to significant appointments following the Congress. As a starter, a new Central Commission for Science under the party leadership has been established. This commission will focus on providing a renewed impetus to accelerate China’s drive to achieve ‘scientific reliance’ and to ease the choke points in the economy, such as the supply chain for semiconductors.

It remains unclear who will head this new commission or who will be on it, however, as scant detail has been made public. It is seen as a direct response to the tough measures adopted by the United States designed to dent China’s ambitions of technology supremacy.

Departure from the past

New appointees to the Politburo come with substantial backgrounds in science as well as a solid track record of running state-owned enterprises. This is a departure from the past.

Instead of inserting financial specialists, Xi appointed two scientists, Liu Guozhong and Zhang Guoqing, as the vice premiers overseeing science, education and industrial policies. This signals that Xi intends to prioritize science and innovation during his third term. The appointment of technocrats to the State Council is seen as a move to strengthen innovation and prepare the Chinese economy, political system and society for potential external shocks.

Chinese supply chains could tip the balance in Ukraine Expert comment NCapeling 29 March 2023

Disrupting supply chains of critical minerals to those supporting Ukraine could give China a key advantage in its wider international trade competition.

Direct military intervention from China into the war on Ukraine, with Chinese troops and airmen appearing at the front line, would be highly escalatory and highly unlikely.

Equipping Russia with weapons and equipment is much more likely – if indeed it hasn’t already happened – and considering the West is supplying armaments to Ukraine, a joust with western technologies would be an interesting development to follow.

But if Chinese weapons underperform in the heat of battle, this may have implications for the current situation with Taiwan and the US, as a poor outcome on the Ukraine front could give the West more confidence over the tensions in the South China Sea. And the use of Chinese weapons in Ukraine would also be a feast for Western technical intelligence to capture.

Creating economic disruption

A much more likely development for China is to put in place export controls on critical minerals for Western powers supplying arms to Ukraine. This is a significant lever which China has used before during its fishing dispute with Japan in 2010 when hi-tech industrial production in Japan was affected by shortages of China-sourced critical minerals. Once normal supplies were resumed, Japan started to stockpile critical mineral reserves.

In October 2020, the Chinese Communist Party (CCP) passed a new statute enabling – when necessary – restriction of critical mineral supplies to third party nations intending to use them for defence and security applications, adding a ‘versatile weapon to Beijing’s arsenal’ in its trade competition with the US.

That legal control has been applied to Lockheed Martin production of Taiwan-bound F-35s and it applies not only to critical minerals mined on the Chinese mainland, but also to Chinese-controlled enterprises within international supply chains, of which there are many.

Responding to any such restrictions by opening up new mines and setting up new supply chains can take more than a decade, so the countries involved may need to start stockpiling critical materials as Japan has been doing since 2010.

Commodity markets also need to be ready for some interesting price wobbles – a persistent problem in critical minerals extractives investment as is overcoming environmental, social, and governance (ESG) challenges in this new game of global supplies.

In addition, those markets include the London Metal Exchange, now owned by Hong Kong Exchanges & Clearing whose biggest shareholder is the Hong Kong government which is struggling to operate with complete independence from Beijing.

Splitting the West’s consensus

By extending the thinking on China’s potential to throttle global critical mineral supply chains and the ensuing latency of extraction from new mining resources, progress to the Paris Agreement 2050 goals on climate change will inevitably be affected.

Given there are no supply chain assurance mechanisms, such as distributed ledger technologies, in place within global mining supply chains, a key issue to overcome would be how the West assures China that critical mineral supplies are not destined for military applications.

But if China’s default position becomes a total refusal to supply client nations unless end-to-end assurances can be achieved to prove non-military use, the West’s aspirations regarding the Paris 2050 goals will certainly be put in jeopardy, or even made unachievable.

An important mechanism of resistance to β-lactam antibiotics is via their β-lactamase–catalyzed hydrolysis. Recent work has shown that, in addition to the established hydrolysis products, the reaction of the class D nucleophilic serine β-lactamases (SBLs) with carbapenems also produces β-lactones. We report studies on the factors determining β-lactone formation by class D SBLs. We show that variations in hydrophobic residues at the active site of class D SBLs (i.e. Trp105, Val120, and Leu158, using OXA-48 numbering) impact on the relative levels of β-lactones and hydrolysis products formed. Some variants, i.e. the OXA-48 V120L and OXA-23 V128L variants, catalyze increased β-lactone formation compared with the WT enzymes. The results of kinetic and product studies reveal that variations of residues other than those directly involved in catalysis, including those arising from clinically observed mutations, can alter the reaction outcome of class D SBL catalysis. NMR studies show that some class D SBL variants catalyze formation of β-lactones from all clinically relevant carbapenems regardless of the presence or absence of a 1β-methyl substituent. Analysis of reported crystal structures for carbapenem-derived acyl-enzyme complexes reveals preferred conformations for hydrolysis and β-lactone formation. The observation of increased β-lactone formation by class D SBL variants, including the clinically observed carbapenemase OXA-48 V120L, supports the proposal that class D SBL-catalyzed rearrangement of β-lactams to β-lactones is important as a resistance mechanism.

In conversation with Speaker Emerita Nancy Pelosi 14 October 2024 — 12:00PM TO 1:00PM Anonymous (not verified) 19 September 2024 Chatham House and Online

The former Speaker of the House of Representatives discusses challenges to American democracy and the importance of leadership in an election year.

As the US gears up for the 2024 Presidential election, the importance of leadership in politics has come to the fore. As the Harris and Trump campaigns move towards election day, the heightened sense of strong leadership is central to the position of both candidates.

Following her first election to the House in 1987, Speaker Emerita Nancy Pelosi has been central to American political leadership for over two decades. Serving as the 52nd Speaker of the House of Representative, Speaker Pelosi rose to become one of the most powerful and consequential Speakers in American political history.

Following the release of her recent book The Art of Power, Speaker Pelosi will discuss how she became a master legislator, working with numerous presidents, her political legacy in the house and her leadership during a contentious time in US politics.

The novel severe acute respiratory syndrome coronavirus (SARS-CoV-2) has emerged to a pandemic and caused global public health crisis. Human angiotensin-converting enzyme 2(ACE2) was identified as the entry receptor for SARS-CoV-2. As a carboxypeptidase, ACE2 cleaves many biological substrates besides angiotensin II to control vasodilatation and vascular permeability. Given the nanomolar high affinity between ACE2 and SARS-CoV-2 spike protein, we investigated how this interaction would affect the enzymatic activity of ACE2. Surprisingly, SARS-CoV-2 trimeric spike protein increased ACE2 proteolytic activity ∼3-10 fold against model peptide substrates, such as caspase-1 substrate and Bradykinin-analog. The enhancement in ACE2 enzymatic function was mediated by the binding of SARS-CoV-2 spike RBD domain. These results highlighted the potential for SARS-CoV-2 infection to enhance ACE2 activity, which may be relevant to the cardiovascular symptoms associated with COVID-19.

In their comment (1) on our publication (2), the authors make two points: (i) they raise concerns about the possible effect of residual NONOate in our study, and (ii) they promote nitrosylcobalamin (NOCbl) supplied by their own company. Both points lack merit for the following reasons. The authors make the astonishing claim that the spectra of nitric oxide (NO•) and cobalamins overlap. Unlike NO•, cobalamin absorbs in the visible region, permitting unequivocal spectral assignment of NOCbl as reported (3). We demonstrated that whereas NOCbl is highly unstable in solution, it is stabilized by the B12 trafficking protein CblC. So even if present, residual NONOate (which is unstable at neutral pH and is removed during the work-up (3)) could not account for the observed difference.The authors then misrepresent our synthetic method, claiming that anaerobic conditions were used to generate nitrocobalamin (NO2Cbl), which results in the transient formation of NOCbl. We synthesized NO2Cbl aerobically using nitrite as described (4); NOCbl is not an intermediate in this ligand exchange reaction. The aerobic instability of NOCbl has been rigorously described by inorganic chemists (3, 5) and raises obvious questions about its purported biological effects as exemplified by the authors' own 2003 JBC publication, which was later withdrawn.As to promoting NOCbl from their company, the authors refer to a synthetic route from a mixture of NO• gas and aquocobalamin. The authors' method (6) has been described as “dubious” by chemists (5). Whereas DEAE NONOate used in our method is widely known as an NO• donor,...

After a thorough read of this paper (1), we wish to clarify that the authors' anaerobic method of synthesis for the production of nitrocobalamin results in the transient formation of nitrosylcobalamin, an unstable intermediate upon exposure to air. We concur that the authors' method results in the production of nitrocobalamin based on the UV-visible data as shown. The authors' adapted anaerobic method consists of mixing hydroxocobalamin hydrochloride with diethylamine NONOate diethylammonium salt in aqueous solution. Of concern, the UV spectrum of nitric oxide overlaps that of all cobalamin species under anaerobic conditions, making any assignments of the binding of nitric oxide to hydroxocobalamin suspect (2). Additionally, the use of acetone to precipitate the authors' product causes precipitation of diethylamine NONOate, resulting in an impure product. As a result, its utility for drawing experimental conclusions is faulty.The product from the authors' anaerobic synthetic method has not been assessed for purity, and the synthetic method itself has not been validated using a stability-indicating method as required by the International Conference on Harmonization (ICH) (ICH Q2B, Validation of Analytical Procedures) methodology, which is a hallmark for analytical characterization. Our nitrosylcobalamin synthesis involves reacting nitric oxide gas with hydroxocobalamin acetate as a heterogeneous mixture in a non-electron-donating solvent followed by rotary evaporation. Our nitrosylcobalamin product is stable in air, releases nitric oxide gas in situ (3), and meets ICH stability guidelines (4). Additionally, our nitrosylcobalamin product demonstrates biological activity, which has not been observed for nitrocobalamin (3, 5).

Heterotrimeric G-proteins are signaling switches broadly divided into four families based on the sequence and functional similarity of their Gα subunits: Gs, Gi/o, Gq/11, and G12/13. Artificial mutations that activate Gα subunits of each of these families have long been known to induce oncogenic transformation in experimental systems. With the advent of next-generation sequencing, activating hotspot mutations in Gs, Gi/o, or Gq/11 proteins have also been identified in patient tumor samples. In contrast, patient tumor-associated G12/13 mutations characterized to date lead to inactivation rather than activation. By using bioinformatic pathway analysis and signaling assays, here we identified cancer-associated hotspot mutations in Arg-200 of Gα13 (encoded by GNA13) as potent activators of oncogenic signaling. First, we found that components of a G12/13-dependent signaling cascade that culminates in activation of the Hippo pathway effectors YAP and TAZ is frequently altered in bladder cancer. Up-regulation of this signaling cascade correlates with increased YAP/TAZ activation transcriptional signatures in this cancer type. Among the G12/13 pathway alterations were mutations in Arg-200 of Gα13, which we validated to promote YAP/TAZ-dependent (TEAD) and MRTF-A/B-dependent (SRE.L) transcriptional activity. We further showed that this mechanism relies on the same RhoGEF-RhoGTPase cascade components that are up-regulated in bladder cancers. Moreover, Gα13 Arg-200 mutants induced oncogenic transformation in vitro as determined by focus formation assays. In summary, our findings on Gα13 mutants establish that naturally occurring hotspot mutations in Gα subunits of any of the four families of heterotrimeric G-proteins are putative cancer drivers.

Nancy Pelosi in Taiwan: What lies ahead for China and the US? Expert comment GBhardwaj 3 August 2022

Chatham House experts examine the implications for Taiwan, China and the United States of Nancy Pelosi’s visit to the island.

China’s fading ties with Washington?

Dr Yu Jie

US House Speaker, Nancy Pelosi’s, visit to Taiwan has plunged China-US relations into a new low as the reservoir of trust forged between the two sides over the last 40 years appears to be almost exhausted.

However, her move will likely not result in the full-scale crisis across the Taiwan strait that some hawkish voices in both Beijing and Washington believe. Instead, Beijing will most likely offer a combination of military posturing toward the US navy and economic sanctions on Taiwanese agricultural and manufacturing products in order to send a clear bellwether to any future potential visits by high-level Western political figures.

Neither Beijing nor Washington has declared a willingness to change the current status quo as the present impasse benefits both governments – but for different reasons. For China, the best approach is to reach a military and economic capability that prevents US engagement with Taiwan without the use of force. For the US, the strategic ambiguity under the Taiwan Relations Act remains an effective card to counter China’s growing military influence in the Indo-Pacific and keep itself relevant within the region as a security guarantor. Yet, both sides have decided to kick the issue of Taiwan’s status down the road, believing that time is ultimately on their side.

Despite a chorus of nationalistic rhetoric, China will be careful not to stumble into an accidental conflict which risks colossal damage on all fronts. Chinese President, Xi Jinping, must weigh all of the options before him as Beijing cannot afford to be perceived as unilaterally seeking to change what it agreed with the US back in 1979 when ties were re-established. If that happens, it will provoke the US political establishment to reach a unanimous agreement to change its ‘One China Policy’ and, ahead of the 20th Communist Party Congress where Xi is expected to be crowned for a historic third term, the last thing he wants is an unnecessary conflict with Taiwan.

The road to escalation?

Dr Bill Hayton

Beijing has chosen to take issue over Nancy Pelosi’s visit to Taiwan in a way that it did not do for other recent US Congressional visits to the island. Several high-ranking US senators visited in April and May this year yet none of these visits triggered the prospect of a cross-strait crisis. So why has Beijing chosen to turn Pelosi’s visit into a stand-off?

Pelosi’s visit is part of a performance in which both actors – the US and China – are playing primarily for their domestic audiences. This comes at a time when ruling circles in Beijing are preparing for the five-yearly Communist Party Congress. Amid a slowing economy and successive COVID-19 variants, Xi Jinping cannot afford to look weak as he prepares the ground for his third term of office. Meanwhile, the US, represented either by President Joe Biden or House Speaker Pelosi, cannot back down at this point without looking weak itself.

Both sides have moved military assets into strategic positions near Taiwan to demonstrate their resolve. Neither side wants confrontation yet neither wishes to be humiliated. Currently, Pelosi’s visit, amid posturing by China, will make the US appear strong, but the consequences are likely to play out over a longer period. Xi Jinping will need to appear to have recaptured the initiative between now and the congress in the autumn when the risk of an incident will be at its greatest.

Taiwan controls several isolated islands that could be pressured by Chinese forces in the event of a future crisis. The Kinmen and Matsu archipelagos lie just a few miles off the coast of the mainland and have been at the centre of previous confrontations. There are also two other points of concern. Pratas Island – known as Dongsha – sits halfway between Taiwan and Hong Kong. Itu Aba – known as Taiping – is the largest of the Spratly Islands in the centre of the South China Sea. All would be vulnerable to an attack by the People’s Liberation Army, the principal military force of China, and the armed wing of the Chinese Communist Party.

A military confrontation between China and the US over Taiwan, or further south in the South China Sea, would have major impacts on regional and global trade. An estimated $300 billion worth of trade passes through the area every month. Japan and South Korea depend heavily on flows of oil and gas through the sea. Exports from Vietnam, Malaysia, Indonesia and the Philippines would also be heavily affected by disruptions to shipping, increased insurance costs and interruptions in inflows of raw materials. The impact on a world economy already suffering major disruption because of the Russian invasion of Ukraine and the lingering effects of COVID-19 would indeed be stark.

Is a shift in US policy on the cards?

Dr Leslie Vinjamuri

Nancy Pelosi’s visit to Taiwan will undoubtedly be seen as a provocation by Beijing – even if it should not be. Pelosi’s trip to the Indo-Pacific, which also includes visits to Singapore, Malaysia, South Korea and Japan, comes at a time of growing tension between the US and China in the region.

It also comes at a time when the divide among Washington’s foreign policy elite is growing, with some arguing that it is time to abandon the country’s policy of ‘strategic ambiguity’, where it refrains from stating how it would react were China to openly and deliberately attack Taiwan. Indeed, recent statements by President Joe Biden have raised questions about whether the US is set to make a policy change. But, since both its ‘One China Policy’ and policy of strategic ambiguity have been largely successful, it would be wise for the US to maintain them.

During her visit, Pelosi is likely to reaffirm the US’ high regard for Taiwan’s democracy and embrace the language of shared values. She has embraced Biden’s framing of international relations as a contest between democracies and autocracies. This alone will continue to exacerbate tensions. It would be a mistake, though, to signal a major policy change away from strategic ambiguity and towards strategic clarity on Taiwan’s status. Even if the US decides later to embrace a policy shift of this size, such a message should be carefully considered and communicated clearly, and not by chance.

Congress has an important role to play but President Joe Biden and his national security team should make the final decision on US policy towards Taiwan. Getting the signals right in international politics is a key part of deterrence and, especially in East Asia, deterring both China and Taiwan’s ambitions is essential. 

Increasing insecurity in the region?

Dr John Nilsson-Wright and Ben Bland

Nancy Pelosi’s visit to Taiwan has provoked mixed responses from US allies across Asia.

For Japanese policymakers, the Taiwan issue is connected to the wider issue of regional security. Fears that a military conflict over the island will inevitably draw Japanese self-defense forces into a shooting war with China – a development that is neither formally mandated under the terms of the US-Japan Mutual Security Treaty nor necessarily constitutionally sanctioned – explains the concerns in Tokyo.

While the Japanese government of Prime Minister Fumio Kishida is increasingly worried about China’s growing military presence in the East and South China Seas, Japan’s heavy trade dependence on China and the country’s economic and security vulnerabilities make it imperative to avoid any further escalation of tensions.

Given Tokyo’s non-recognition policy towards Taiwan, Japanese ties with Taipei are handled informally by politicians of the governing Liberal Democratic Party (LDP), rather than at cabinet or foreign ministry level, and in recent weeks and months there has been an increase in visits by cross party delegations from Japan.

The death of former Prime Minister Shinzo Abe as removed from public life a vocal advocate in support of enhanced ties between Tokyo and Taipei, but with public opinion in Japan increasingly tilting in an anti-Chinese direction, and with younger politicians favouring a more combative approach towards Beijing, there is a risk that the government will face pressure at home to toughen its language on Taiwan. Bolstering deterrence through increased military cooperation among allies, along with a graduated increase in defence spending, is the best way of limiting risk over Taiwan.

Nevertheless, privately, many officials in Tokyo are likely to have viewed the Pelosi visit as an unhelpful intervention and will be puzzled and perhaps frustrated by the apparent inability of the Biden administration to persuade the US Speaker of the House of Representatives to cancel her visit.

In South Korea, the government of President Yoon Suk-yeol, faces similar pressures to Japan, given the heavy dependence of the South Korean economy on China for trade and investment opportunities.

Pelosi’s visit to the region will strikingly not include meetings with either the president or Foreign Minister Park Jin. With Yoon on vacation and Park attending the ASEAN Regional Forum meeting in Cambodia, the absence of high profile engagements for Pelosi might seem to be a purely practical matter, but Seoul may also be seeking to avoid antagonizing Beijing at a time when the Chinese government is seeking to pressure South Korea not to enhance alliance coordination with the United States and Japan or to expand its commitment to the controversial Terminal High Altitude Area Defence (THAAD) missile defence system.

As in Japan, public opinion in South Korea is increasingly anti-Chinese, but the logic of regional economic and security uncertainty, requires the Yoon government to avoid getting trapped in a worsening stand-off with Beijing.

SVB collapse shows interest rate financial stability threat Expert comment LJefferson 15 March 2023

Governments must resist pressure to relax post-financial crisis regulation, while central banks should moderate their attack on inflation if financial stability is at risk.

The collapse of California’s Silicon Valley Bank (SVB) on 10 March has triggered a wave of volatility in global bank equity prices, raised questions about whether US bank regulation and its tech industry funding model are fit for purpose, and forced a rethink on the extent and pace of monetary policy tightening appropriate for the US and other advanced economies.

SVB was the US’s 16th largest bank with total assets of $212bn at the end of 2022 and a presence in eight countries around the world, including the UK. Since it was founded 40 years ago, it has maintained a strong focus on the technology sector, claiming recently that nearly half of all US venture-backed technology and life science companies banked with it. Partly as a consequence, some 95 per cent of its deposits came from corporates and hedge funds, far higher than the one-third typical of similarly sized banks.

What led to SVB’s collapse?

Ironically, SVB’s failure did not result from its core business model of serving a relatively high-risk and fast-growing sector, but rather from a dramatic failure in liquidity management. During the pandemic, SVB saw a very large inflow of corporate deposits. But rather than disincentivizing depositors or investing the funds attracted in assets of matching maturity, it chose to invest them in low credit risk, but long maturity bonds attracted by a small pick-up in return over shorter-term assets. 

When US interest rates began to rise rapidly in 2022 following Russia’s invasion of Ukraine, the value of SVB’s long-term bond portfolio declined sharply. It was left facing a large capital loss of some $15bn, roughly equivalent to its total shareholder funds. The management attempted to repair SVB’s balance sheet last week by crystalizing some of the loss and raising new capital.

But when this failed, the US supervisory authorities had no choice but to step in and close the institution.  This action was quickly followed by emergency action from other regulators vis-a-vis SVB subsidiaries and offices around the world.

The US entity has formally been taken over by the FDIC and a bridge bank established. All depositors have had their funds guaranteed, going beyond the normal federal deposit insurance limit of $250,000 per customer. However, bond holders and equity holders have been wiped out. The authorities have said that any loss will be covered by the industry as a whole via the FDIC.

In the UK, the Bank of England was able to sell the ring-fenced UK subsidiary of SVB to HSBC for £1 over the weekend, so that all its depositors and other liability holders have effectively had their funds guaranteed. In contrast to previous Bank of England rescues (such as Johnson Matthey Bank in 1984, the ‘small banks’ crisis in 1991 and the global financial crisis in 2008-9) no public money has been put at risk.

Four key questions

SVB’s rapid collapse raises four central questions:

First, how was it that the bank was able to take on such a risky interest rate maturity mismatch in its US operations? Maturity transformation is standard banking industry practice, but it is usually closely monitored by regulators who place limits on the extent of interest rate maturity mismatch and require liquidity buffers to offset the risk of deposit flight and forced asset sales.

SVB’s very high concentration of corporate deposits as compared to ‘sticky’ retail deposits, means that the risk of deposit flight was unusually high and so the bank should have been more, not less, cautious in its liquidity policy. SVB was classed as a regional bank in the US which means that it did not have to meet international regulatory standards under Basle III. And in 2018, the Trump administration approved legislation removing the post-financial crisis requirement that banks with assets under $250bn submit to stress testing and relaxing liquidity buffer requirements.

But it is still hard to understand why regulators allowed SVB to commit such a classic banking error. On Monday, the Federal Reserve ordered an inquiry into what it has correctly described as a regulatory failure. This should look at the role played by all the elements of the oversight system including the auditors, KPMG.

Second, does SVB’s failure reflect a much bigger underlying risk in the US banking sector, and potentially other banking systems around the world, built up over the prolonged period of ultra-low interest rates? SVB’s collapse was followed by the failure of the $110bn Signature Bank in New York, as well as sharp falls in US regional bank stock prices – by close of play on 14 March, the S&P Regional Bank Index was down 22 per cent on a week before, with some individual bank stocks seeing much sharper falls.  

To the extent that banks have been covered by international bank regulatory requirements, the risk of a much broader problem should be limited because stress testing and other regulatory tests would have looked at precisely the scenario that has happened. Even where large market losses have been incurred, capital buffers should be sufficient to cover them. But as SVB has shown, there are some large banks that are seemingly not required to follow international rules, while the latest developments at Credit Suisse indicate that market concerns may still arise when other factors are in play.

Third, how far, in the light of the potential vulnerability in banking systems, should central banks in advanced countries moderate their efforts to squeeze out inflationary pressures? While inflation already appears to have peaked in many economies and the pace of interest rate rises was expected to slow, inflation is far from vanquished, as recent data in the US has demonstrated.

Fourth, does the failure of SVB tell us something new about the financial risks facing the high technology sector?  It was remarkable that a single (and not particularly large, by international standards) financial institution could have played such a central role in the tech sector in both the US and UK. 

Why was this the case and does it reflect special features of the tech/start-up sector (e.g. the need for substantial cash deposits to cover relatively large negative cash flows in the early years of operation, or the need for highly specialized lending expertise). If so, should governments take steps to mitigate such risks, given the outsized importance of this sector in many national economic strategies?

HIV Type 1 (HIV-1) and simian immunodeficiency virus (SIV) display differential replication kinetics in macrophages. This is because high expression levels of the active host deoxynucleotide triphosphohydrolase sterile α motif domain and histidine-aspartate domain–containing protein 1 (SAMHD1) deplete intracellular dNTPs, which restrict HIV-1 reverse transcription, and result in a restrictive infection in this myeloid cell type. Some SIVs overcome SAMHD1 restriction using viral protein X (Vpx), a viral accessory protein that induces proteasomal degradation of SAMHD1, increasing cellular dNTP concentrations and enabling efficient proviral DNA synthesis. We previously reported that SAMHD1-noncounteracting lentiviruses may have evolved to harbor RT proteins that efficiently polymerize DNA, even at low dNTP concentrations, to circumvent SAMHD1 restriction. Here we investigated whether RTs from SIVmac239 virus lacking a Vpx protein evolve during in vivo infection to more efficiently synthesize DNA at the low dNTP concentrations found in macrophages. Sequence analysis of RTs cloned from Vpx (+) and Vpx (−) SIVmac239–infected animals revealed that Vpx (−) RTs contained more extensive mutations than Vpx (+) RTs. Although the amino acid substitutions were dispersed indiscriminately across the protein, steady-state and pre-steady-state analysis demonstrated that selected SIVmac239 Vpx (−) RTs are characterized by higher catalytic efficiency and incorporation efficiency values than RTs cloned from SIVmac239 Vpx (+) infections. Overall, this study supports the possibility that the loss of Vpx may generate in vivo SIVmac239 RT variants that can counteract the limited availability of dNTP substrate in macrophages.

How Beijing is closing surveillance gaps in the South China Sea The World Today iallan.drupal 15 October 2024

The discovery of a new radar system on China’s Triton Island military base shows that Beijing is rapidly developing its intelligence capacities in contested waters, write John Pollock and Damien Symon.

New satellite images reveal how the Chinese military is dramatically expanding its capabilities on Triton Island, which looks set to become a one of Beijing’s key signal intelligence bases in the South China Sea.

Once completed, the radar system would significantly increase China’s signals intercept and electronic warfare capabilities across the disputed Paracel Islands archipelago and add to a wider surveillance network spanning much of the South China Sea.

The enhanced facility on Triton is likely to offer a challenge to China’s competitors in the region and internationally.

China seized control of the Paracels from Vietnam in a 1974 naval battle, and competition for access to it waters has intensified since the recent discovery of oil and gas reserves. Chinese and Vietnamese maritime militia clashed off the coast of Triton in 2014.

In addition, American, British and Australian naval forces have for the past decade patrolled the waters to collectively challenge China’s contested ‘nine-dash-line’ claim to large stretches of the South China Sea. 

Overlapping anti-stealth network

A year after work was first identified on Triton, satellite images from Maxar have helped build a clearer picture of Beijing’s efforts to defend this strategic waterway.

The most striking development is the construction of a new radar system, known as SIAR – synthetic impulse and aperture radar – which purportedly detects stealth aircraft. The counter-stealth radar on Triton is characterized by its distinctive octagonal structure, which resembles another SIAR system built by China on Subi Reef in the Spratly Islands, south of the Paracels, in 2017. A half-completed tower also sits near the SIAR radar on Triton, which is likely to be the operations centre.

Once completed, the radar on Triton will form what is believed to be a wider network of at least three overlapping counter-stealth radars built across Chinese bases in the South China Sea over the past decade, including on Hainan Island, home to several Chinese naval bases. 

The positioning of the radar on Triton, 320km south of Hainan, is telling, says J. Michael Dahm, Senior Resident Fellow for Aerospace and China Studies at the Mitchell Institute. 

‘SIAR radars cannot see over the curve of the Earth, which means there is a gap in China’s air surveillance coverage between Subi Reef and Hainan Island. The Triton Island site will help close that gap’, said Dahm.

The aim, he suggests, is to give China contiguous counter-stealth radar coverage of the South China Sea.

More construction underway

The satellite images reveal other building projects on Triton. One is a large pad at the end of the road network which will probably be used as a launching point for a mobile anti-ship missile battery. The building at the northeast end of the road is probably a storage building for missile transport vehicles. 

Diminishing Vietnam’s options

The development of a new counter-stealth radar system and other suspected signals intercept structures on Triton represents a notable increase in China’s intelligence capabilities in the Paracels. The Chinese Communist Party has not disclosed the purpose of the building work on Triton, but its effects on regional and global competitors are likely to be wide ranging.

For Vietnam, which is rapidly expanding its own bases in the South China Sea, the intelligence structures on Triton would significantly diminish its capacity to operate undetected in the area. Alongside existing radar on Triton which can detect sea-going vessels, Beijing now has the potential to track Vietnamese air movements and gain forewarning of Hanoi’s manoeuvres in the area, including efforts to access oil and gas deposits.

The desire to strengthen control over these resources may explain why China is fortifying Triton Island, says Bill Hayton, Associate Fellow in the Asia-Pacific Programme, Chatham House. ‘The developments might be a warning that China is planning to mount another drilling expedition’, he suggests.
