On August 11th, China devalued its currency, the yuan, by 1.9%. The next day it devalued it by a further 1.6% and on the next day by a further 1.1%. Even though the total devaluation was relatively small, especially given a much bigger revaluation over the previous three years (see chart below), traders in world markets greeted the news with considerable pessimism. Stock markets around the world fell. For example, the US Dow Jones was down by 1.1%, the FTSE 100 was down by 2.5% and the German DAX by 5.8%.
There are three major concerns of investors about the devaluation. The first is that a weaker yuan will make other countries’ exports more expensive in China, thereby making it harder to export to China. At the same time Chinese imports into the rest of the world will be cheaper, thereby making it harder for domestic producers to compete with Chinese imports.
The second is that cheaper Chinese imports will put downward pressure on prices at a time when inflation rates in the major economies are already below target rates. The fear of deflation has not gone away and this further deflationary twist will intensify such fears and possibly dampen demand.
The third is that the devaluation is taken as a sign that the Chinese authorities are worried about a slowing Chinese economy and are using the devaluation to boost Chinese exports. The rapidly expanding Chinese economy has been one of the major motors of the global economy in recent years and hence a slowing Chinese economy is cause for serious concern at a time when the global economy is still only very slowly recovering from the shock of the financial crisis of 2007–8
But just how worried should the rest of the world be about the falling yuan? And will it continue to fall, or could this be seen as a ‘one-off’ correction? What effect will it have on the macroeconomic policies of the USA, the eurozone and other major countries/regions? The following articles analyse Chinese policy towards its currency and the implications for the rest of the world.

It was argued in an earlier blog on the Greek debt crisis that a deus ex machina was needed to find a resolution to the impasse between Greece and its creditors. The most likely candidate for such as role was the IMF.
Three days before the Greek referendum on whether or not to accept the Troika’s proposals, the IMF has stepped onto the stage. To the undoubted surprise of the other two partners in the Troika (the European Commission and the ECB), the IMF argues that Greece’s debts are unsustainable and that much more is needed than a mere bailout (which simply rolls over the debt).
According to the IMF, Greece needs €52bn of extra funds between October 2015 and December 2018, large-scale debt relief, a 20-year grace period before making any debt repayments and then 
debt repayments spread over the following 20 years. In return, Greece should commit to supply-side reforms to cut out waste, reduce bureaucracy, improve tax collection methods and generally improve the efficiency of the economic system.
It would also have to agree to the previously proposed primary budget surplus (i.e. the budget surplus excluding debt repayments) of 1 per cent of GDP this year, rising to 3.5 per cent in 2018.
So it this what commentators have been waiting for? What will be the reaction of the Greeks and the other two partners in the Troika? We shall see.

The negotiations between Greece and the ‘troika’ of creditors (the IMF, the European Commission and the ECB) have seen many twists and turns before breaking down on 26 June. Throughout, both sides have sought to give as little as possible while seeking a compromise. Both sides have claimed that their position is reasonable, even though a gulf has remained between them.
What has been playing out is a high-stakes game, where the optimum outcome for each side is quite different.
Greece seeks bailout terms that would allow it to achieve a smaller primary budget surplus (but still a surplus in the midst of a deep recession). The surplus would be achieved largely through tax rises on the wealthy rather than further cuts that would hit the poor hard. It is also seeking a substantial amount of debt forgiveness to make servicing the remaining debt possible.
The troika is seeking a larger budget surplus than the Greeks are willing to contemplate. This, it maintains, should be achieved largely through additional cuts in government expenditure, including further reductions in pensions and in public-sector wages.
Both sides used threats and promises as the negotiations became more and more acrimonious.
The troika threatened to withhold the final €7.2bn of the bailout necessary to pay the €1.6bn due to the IMF on 30 June, unless the Greeks accepted the terms of the austerity package put to them. The Greek Prime Minister, Alexis Tsipras, in rejecting the proposals, called a referendum on the package. This threatens the stability of the eurozone as a No vote, if it led to a Greek exit from the eurozone, could undermine confidence in monetary union. After all, if Greece could be forced out, other countries facing severe difficulties might also be forced out at some point in the future. Once a country leaves the eurozone, the monetary union becomes more like a system of pegged exchange rates. And pegged exchange rates are open to destabilising speculation at times of economic divergence.
A Greek exit from the euro (dubbed ‘Grexit’) is seen as undesirable by most Greeks and by most politicians in the rest of Europe. The optimum for both sides collectively would be a compromise, which saw more modest cuts by Greece and the eurozone remaining intact. By both sides seeking to maximise their own position, the Nash equilibrium is certainly not the best outcome.
But as long as the troika believes that the Greeks are likely to vote Yes to the proposed bailout terms, it still hopes to get the outcome that is best from its point of view – an outcome that would probably involve regime change. And as long as the Greek government hopes that a No vote will force the troika to think again and come back with less austere proposals, it still hopes to get the outcome that is best from its point of view. But the outcome of this game of ‘chicken’ could well be Grexit and a Nash equilibrium that neither side wants.
But while the endgame is being played out by politicians, people in Greece are suffering. Policies of severely depressing aggregate demand to turn a large budget deficit into a primary budget surplus have led to the economy shrinking by 26%, overall unemployment of 27% and youth unemployment of over 60%. The Greeks truly believe themselves to be stuck between a rock and a hard place.
The following articles look at the nature of the ‘game’ being played and at the effects on the Greek economy, both of the proposed austerity package proposed by the troika and Grexit. They also look at the knock-on effects for the eurozone, the EU and the global economy.

With worries about Greek exit from the eurozone, with the unlikelihood of further quantitative easing in the USA and the UK, with interest rates likely to rise in the medium term, and with Chinese growth predicted to be more moderate, many market analysts are forecasting that stock markets are likely to fall in the near future. Indeed, markets are already down over the past few weeks. Since late April/early May, the FTSE is down 4.5%; the German DAX index is down 7.0%; the French CAC40 index is down 6.9%; and the US Dow Jones index is down 2.3%. But does this give us an indication of what is likely to happen over the coming months?
If stock markets were perfectly efficient, then all possible information about the future will already have been taken into account and will all be reflected in current share prices. It would be impossible to ‘get ahead of the game’.
It is only if market participants have imperfect information and if you have better information than other people that you can are likely to predict correctly what will happen. Even then, the markets might be buffeted by random and hence unpredictable shocks.
Some people correctly predicted things in the past: such as crashes or booms. But in many cases, this was luck and their subsequent predictions have proved to be wrong. When financial advisers or newspaper columnists give advice, they are often wrong. If they were reliably right, then people would follow their advice and markets would rapidly adjust to their predictions.
If Greece were definitely to exit the euro, if interest rates were definitely to rise in the near future, if it became generally believed that stock markets were overvalued, then stock markets would probably fall. But these things may not happen. After all, people have been predicting a rise in interest rates from their ultra-low levels for many months – and it hasn’t happened yet, and may not happen for some time to come – but it may!
If you want to buy shares, you might just as well buy them at random – or randomly sell any you already have. As Tetlock says, quoted in the Nasdaq article:
“Even the most astute observers will fail to outperform random prediction generators – the functional equivalent of dart-throwing chimps.”
And yet, people do believe that they can predict what is going to happen to stock markets – if not precisely, then at least roughly. Are they deluded, or can looking calmly at likely political and economic events put them one step ahead of other people who perhaps behave more reactively and emotionally?

- Is there an asymmetry between buying and selling behaviour in stock markets?
- Will ignoring stock market forecasts make people better investors?
- “The stock market prices suggest that investors believe both the Federal Reserve and the Bank of England are bluffing about raising interest rates. That may be so, but it is an extremely risky game of chicken for investors to play.” Explain and discuss.
With talks ongoing about resolving the Greek debt crisis, it is clear that there is no agreement that will satisfy both sides – the Greek government and the troika of lenders (the IMF, the ECB and the European Commission). Their current negotiating positions are irreconcilable. What is needed is something more fundamental to provide a long-term solution. What is needed is a ‘deus ex machina‘.
A deus ex machina, which is Latin for ‘god from a machine’, was a device used in Greek tragedy to solve an impossible situation. A god would appear from above, lowered by a crane, or from below through a trap door, and would put everything right. The tragedy would then be given a happy ending.
So what possible happy ending could be brought to the current Greek tragedy and who could be the deus ex machina?
The negotiations between Greece and the troika currently centre on extending credit by €7.2bn when existing debts come up for repayment. There are repayments currently due to the IMF, or by the end of June, of €1.5bn and more in July, September and December (another €3.2bn). There are also €6.7bn of Greek bonds held by the ECB, as part of the 2010 bailout programme, that are due for repayment in July and August. Without the €7.2 billion bailout, Greece will be unable to meet these debt repayments, which also include Treasury bills.
But the troika will only release the funds in return for harsh austerity measures, which involve further cuts to pensions and public expenditure. Greece would be required to run a substantial budget surplus for many years.
Greece could refuse, but then it would end up defaulting on debt and be forced out of the euro. The result would probably be a substantial depreciation of a newly restored drachma, rising inflation and many Greeks suffering even greater hardship – at least for a period of time.
So what is the possible deus ex machina? If you’re looking for a ‘god’ then it is best, perhaps, to look beyond the current actors. Perhaps the Americans could play the role in finding a solution to the impasse. Perhaps a small group of independent experts or politicians, or both, could find one. In either case, the politics of the situation would have to be addressed as well as the economics and finance.
And what would be the ‘fix’ to satisfy both sides? Ultimately, this has to allow Greek debt to be sustainable without further depressing demand and undermining the fabric of Greek society. This would almost certainly have to involve a large measure of debt forgiveness (i.e. debts being written off). It also has to avoid creating a moral hazard, whereby if the Greeks are seen as being ‘let off lightly’, this might encourage other indebted eurozone countries to be less willing to reduce their debts and make demands for forgiveness too.
Ultimately, the issue is a political one, not an economic one. This will require clever negotiation and, if there is a deus ex machina, clever mediation too.
