The renminbi seems to be back in business as a Chinese tool of retaliation against US tariffs. A 1.5 per cent fall in the currency early this month in response to proposed new US tariffs was only a start. Since the middle of August the renminbi has weakened further, and the exchange rate is now 4 per cent weaker than at the start of the month. We may well see more of a ‘weaponized’ renminbi, but there are four good reasons why Beijing might be wise to think before shooting.

The first has to do with how China seeks to promote its place in the world. China has been at pains to manage the collapse of its relations with the US in a way that allows it to present itself as an alternative pillar of global order, and as a source of stability in the international system, not to mention moral authority. This has deep roots.

Anyone investigating the history of Chinese statecraft will quickly come across an enduring distinction in Chinese thought: between wang dao, the kingly, or righteous way, and ba dao, the way of the hegemon. Since Chinese thinkers and officials routinely describe US behaviour since the Second World War as hegemonic, it behoves Chinese policymakers to do as much as possible to stay on moral high-ground in their behaviour towards Washington. Only in that way would President Xi be able properly to assert China’s claim to leadership.

Indeed, China has a notable track record of using exchange rate stability to enhance its reputation as a force for global stability. Both in the aftermath of the Asian crisis in 1997, and of the Global Financial Crisis in 2008, Chinese exchange rate stability was offered as a way of demonstrating China’s trustworthiness and its commitment to multilateral order.

Devaluing the renminbi in a meaningful way now might have a different rationale, but the cost to China’s claim to virtue, and its bid to offer itself as a guardian of global stability, might be considerable.

That’s particularly true because of the second problem China has in thinking about a weaker renminbi: it may not be all that effective in sustaining Chinese trade. One reason for this is the increasing co-movement with the renminbi of currencies in countries with whom China competes.

As the renminbi changes against the dollar, so do the Taiwan dollar, the Korean won, the Singapore dollar and the Indian rupee. In addition, the short-run impact of a weaker renminbi is more likely to curb imports than to expand exports, and so its effects might be contractionary. 

An ineffective devaluation of the renminbi would be particularly useless because of the third risk China needs to consider, namely the risk of retaliation by the US administration. Of this there is already plenty of evidence, of course.

The US Treasury’s declaration of China as a ‘currency manipulator’ on 5 August bears little relationship to the actual formal criteria that the Treasury uses to define that term, but equally the US had warned the Chinese back in May that these criteria don’t bind its hand. By abandoning a rules-based approach to the definition of currency manipulation, the US has opened wide the door to further antagonism, and Beijing should have no doubt that Washington will walk through that door if it wants to.

The fourth, and possibly most self-destructive, risk that China has to consider is that a weaker renminbi might destabilize China’s capital account, fuelling capital outflows that would leave China’s policymakers feeling very uncomfortable.

Indeed, there is already evidence that Chinese residents feel less confident that the renminbi is a reliable store of value, now that there is no longer a sense that the currency is destined to appreciate against the dollar. The best illustration of this comes from the ‘errors and omissions’, or unaccounted-for outflows, in China’s balance of payments.

The past few years have seen these outflows rise a lot, averaging some $200 billion per year during the past four calendar years, or almost 2 per cent GDP; and around $90 billion in the first three months of 2019 alone. These are scarily large numbers.

The risk here is that Chinese expectations about the renminbi are ‘adaptive’: the more the exchange rate weakens, the more Chinese residents expect it to weaken, and so the demand for dollars goes up. In principle, the only way to deal with this risk would be for the People's Bank of China (PBOC) to implement a large, one-off devaluation of the renminbi to a level at which dollars are expensive enough that no one wants to buy them anymore.

This would be very dangerous, though: it presupposes that the PBOC could know in advance the ‘equilibrium’ value of the renminbi. It would take an unusually brave central banker to claim such foresight, especially since that equilibrium value could itself be altered by the mere fact of such a dramatic change in policy.

No one really knows precisely by what mechanism capital outflows from China have accelerated in recent years, but a very good candidate is tourism. The expenditure of outbound Chinese tourists abroad has risen a lot in recent years, and that increase very closely mirrors the rise in ‘errors and omissions’. So the suspicion must be that the increasing flow of Chinese tourists – nearly one half of whom last year simply travelled to capital-controls-free Hong Kong and Macao – is just creating opportunities for unrecorded capital flight.

This raises a disturbing possibility: that the most effective way for China to devalue the renminbi without the backfire of capital outflows would be simultaneously to stem the outflow of Chinese tourists. China has form in this regard, albeit for differing reasons: this month it suspended a programme that allowed individual tourists from 47 Chinese cities to travel to Taiwan.

A more global restriction on Chinese tourism might make a devaluation of the renminbi ‘safer’, and it would have the collateral benefit of helping to increase China’s current account surplus, the evaporation of which in recent years owes a lot to rising tourism expenditure and which is almost certainly a source of unhappiness in Beijing, where mercantilism remains popular.

But a world where China could impose such draconian measures would be one where nationalism has reached heights we haven’t yet seen. Let’s hope we don’t go there.

Summary

• Multilateralism may, in theory, put countries on an equal economic footing. But in practice the concept has often relied on an anchor government to create and preserve global norms. Under the presidency of Donald Trump, the US has accelerated its move away from leadership in global economic governance. This shift threatens the monetary and trading systems that have long underpinned globalization. Does the global economy need – and can it find – another leader to take America’s place?
• In the monetary sphere, the US role in providing an internationalized currency has endured relatively well, even though the US’s formal anchoring of the global exchange rate system collapsed nearly half a century ago. Governance of the US dollar and of the dollar-based financial system has largely been left to competent technocrats.
• Recent US political uncertainty has encouraged other governments, particularly in the eurozone and China, in their long-standing quest to supplant the dollar. But these economies’ internal weaknesses have prevented their respective currencies from playing a wider role. Arguments for a multipolar system exist, yet network effects plus the dollar’s superior institutions mean it has retained its dominance.
• In trade, the US role as anchor of the global legal order was already looking unreliable before Trump’s election. Washington has faced growing resistance at home to its global responsibilities. This, together with the idiosyncratic rise of countries such as China, has made the US an increasingly unreliable and narrowly transactional leader.
• More recently, hard-to-regulate issues such as foreign direct investment, technology transfer and data flows, often with national security implications, are increasingly undermining the ideal of multilateral global governance. Institutions such as the World Trade Organization, focused on cross-border trade in goods and services, are becoming less relevant.
• Recent US actions against the Chinese technology firm Huawei show the Trump administration’s willingness to decouple the US market from China and try to drag other economies with it. As far as possible, other governments should resist taking sides. A complete separation of the global economy into rival spheres is probably unfeasible, and certainly highly undesirable.
• Although future US administrations may be less wantonly destructive, it is not realistic to expect them to resume America’s former role. Nor can the US simply be replaced with another power. Instead, coalitions of governments with interests in international rules-based orders will need to form. These coalitions will need to show due deference to issues like investment and national security, especially where attempts to bind governments by multilateral rules are likely to provoke a severe backlash from domestic constituencies.

COVID-19 is a sharp reminder of why trade and climate policy matters. How can governments maintain access to critical goods and services, and ensure global supply chains function in times of crisis?

The timing of many trade negotiations is now increasingly uncertain, as are the UK’s plans to host COP26 in November. Policy work continues, however, and the EU has released its draft negotiating text for the new UK-EU trade deal, which includes a sub-chapter specifically devoted to climate. 

This is a timely reminder both of the pressing need for the UK to integrate its trade and climate policymaking and to use the current crisis-induced breathing space in international negotiations - however limited - to catch up on both strategy and priorities on this critical policy intersection.

The UK government has moved fast to reset its external trade relations post-Brexit. In the past month it formally launched bilateral negotiations with the EU and took up a seat at the World Trade Organization (WTO) as an independent member. Until the COVID-19 crisis hit, negotiations were also poised to start with the US.

The UK is also in the climate spotlight as host of COP26, the most important international climate negotiation since Paris in 2015, which presents a vital opportunity for the government to show leadership by aligning its trade agenda with its climate and sustainability commitments in bold new ways.

Not just an empty aspiration

This would send a signal that ‘Global Britain’ is not just an empty aspiration, but a concrete commitment to lead.

Not only is concerted action on the climate crisis a central priority for UK citizens, a growing and increasingly vocal group of UK businesses committed to decarbonization are calling on the government to secure a more transparent and predictable international market place that supports climate action by business.

With COP26, the UK has a unique responsibility to push governments to ratchet up ambition in the national contributions to climate action – and to promote coherence between climate ambition and wider economic policymaking, including on trade. If Britain really wants to lead, here are some concrete actions it should take.

At the national level, the UK can pioneer new ways to put environmental sustainability – and climate action in particular - at the heart of its trade agenda. Achieving the government’s ambitious Clean Growth Strategy - which seeks to make the UK the global leader in a range of industries including electric cars and offshore wind – should be a central objective of UK trade policy.

The UK should re-orient trade policy frameworks to incentivize the shift toward a more circular and net zero global economy. And all elements of UK trade policy could be assessed against environmental objectives - for example, their contribution to phasing out fossil fuels, helping to reverse overexploitation of natural resources, and support for sustainable agriculture and biodiversity.

In its bilateral and regional trade negotiations, the UK can and should advance its environment, climate and trade goals in tandem, and implementation of the Paris Agreement must be a core objective of the UK trade strategy.

A core issue for the UK is how to ensure that efforts to decarbonise the economy are not undercut by imports from high-carbon producers. Here, a ‘border carbon adjustment (BCA)’ - effectively a tax on the climate pollution of imports - would support UK climate goals. The EU draft negotiating text released yesterday put the issue of BCAs front and centre, making crystal clear that the intersection of climate, environment and trade policy goals will be a central issue for UK-EU trade negotiations.

Even with the United States, a trade deal can and should still be seized as a way to incentivize the shift toward a net zero and more circular economy. At the multilateral level, as a new independent WTO member, the UK has an opportunity to help build a forward-looking climate and trade agenda.

The UK could help foster dialogue, research and action on a cluster of ‘climate and trade’ issues that warrant more focused attention at the WTO. These include the design of carbon pricing policies at the border that are transparent, fair and support a just transition; proposals for a climate waiver for WTO rules; and identification of ways multilateral trade cooperation could promote a zero carbon and more circular global economy.  

To help nudge multilateral discussion along, the UK could also ask to join a critical ‘path finder’ effort by six governments, led by New Zealand, to pursue an agreement on climate change, trade and sustainability (ACCTS). This group aims to find ways forward on three central trade and climate issues: removing fossil fuel subsidies, climate-related labelling, and promoting trade in climate-friendly goods and services.

At present, the complex challenges at the intersection of climate, trade and development policy are too often used to defer or side-step issues deemed ‘too hard’ or ‘too sensitive’ to tackle. The UK could help here by working to ensure multilateral climate and trade initiatives share adjustment burdens, recognise the historical responsibility of developed countries, and do not unfairly disadvantage developing countries - especially the least developed.

Many developing countries are keen to promote climate-friendly exports as part of wider export diversification strategies  and want to reap greater returns from greener global value chains. Further, small island states and least-developed countries – many of which are Commonwealth members – that are especially vulnerable to the impacts of climate change and natural disasters, need support to adapt in the face of trade shocks and to build climate-resilient, trade-related infrastructure and export sectors.

As an immediate next step, the UK should actively support the growing number of WTO members in favour of a WTO Ministerial Statement on environmental sustainability and trade. It should work with its key trading partners in the Commonwealth and beyond to ensure the agenda is inclusive, supports achievement of the UN Sustainable Development Goals (SDGs) and helps developing countries benefit from a more environmentally sustainable global economy.

As the UK prepares to host COP26, negotiates deals with the EU and US, and prepares for its first WTO Ministerial meeting as an independent member, it must show it can lead the way nationally, bilaterally, and multilaterally. And to ensure the government acts, greater engagement from the UK’s business, civil society and research sectors is critical – we need all hands on deck to forge and promote concrete proposals for aligning UK trade policy with the climate ambition our world needs.

There were several notable achievements during last week’s Spring meetings. The Fund’s frank set of forecasts for world GDP growth are a grim but valuable reminder of the scale of the crisis we are facing, and the Fund’s richer members will finance a temporary suspension on payments to the IMF for 29 very poor countries.

Most importantly, a boost to the Fund’s main emergency facilities - the Rapid Credit Facility and the Rapid Financing Instrument - now makes $100bn of proper relief available to a wide range of countries. But the core problem is that the vast bulk of the Fund’s firepower is effectively inert.

This is because of the idea of 'conditionality', which underpins almost all of the IMF’s lending relationships with member states. Under normal circumstances, when the IMF is the last-resort lender to a country, it insists that the borrowing government tighten its belt and exercise restraint in public spending.

This helps to achieve three objectives. One is to stabilise the public debt burden, to ensure that the resources made available are not wasted. The second is to limit the whole economy’s need for foreign exchange, a shortage of which had prompted a country to seek IMF help in the first place. And the third is to ensure that the IMF can get repaid.

Role within the international monetary system

Since the IMF does not take any physical collateral from countries to whom it is lending, the belt-tightening helps to act as a kind of collateral for the IMF. It helps to maximise the probability that the IMF does not suffer losses on its own loan portfolio — losses that would have bad consequences for the Fund’s role within the international monetary system.

This is a perfectly respectable goal. Walter Bagehot, the legendary editor of The Economist, established modern conventional wisdom about managing panics. Relying on a medical metaphor that feels oddly relevant today, he said that a panic 'is a species of neuralgia, and according to the rules of science you must not starve it.' 

Managing a panic, therefore, requires lending to stricken borrowers 'whenever the security is good', as Bagehot put it. The IMF has had to invent its own form of collateral, and conditionality is the result. The problem, though, is that belt-tightening is a completely inappropriate approach to managing the current crisis.

Countries are stricken not because they have indulged in any irresponsible spending sprees that led to a shortage of foreign exchange, but because of a virus beyond their control. Indeed, it would seem almost grotesque for the Fund to ask countries to cut spending at a time when, if anything, more spending is needed to stop people dying or from falling into a permanent trap of unemployment.

The obvious solution to this problem would be to increase the amount of money that any country can access from the Fund’s emergency facilities well beyond the $100bn now available. But that kind of solution would quickly run up against the IMF’s collateral problem.

The more the IMF makes available as 'true' emergency financing with few or no strings attached, the more it begins to undermine the quality of its loan portfolio. And if the IMF’s senior creditor status is undermined, then an important building block of the international monetary system would be at risk.

One way out of this might have been an emergency allocation of Special Drawing Rights, a tool last used in 2009. This would credit member countries’ accounts with new, unconditional liquidity that could be exchanged for the five currencies that underpin the SDR: the dollar, the yen, the euro, sterling and the renminbi. That will not be happening, though, since the US is firmly opposed, for reasons bad and good.

So in the end the IMF and its shareholders face a huge problem. It either lends more money on easy terms without the 'collateral' of conditionality, at the expense of undermining its own balance sheet - or it remains, in systemic terms, on the sidelines of this crisis.

And since the legacy of this crisis will be some eye-watering increases in the public debt burdens of many emerging economies, the IMF’s struggle to find a way to administer its medicine will certainly outlive this round of the coronavirus outbreak.
