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.

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.

Ahead of the G20 meeting in Seoul on 11 and 12 November 2010, there has been much debate about exchange rates and the dangers of currency and trade wars. This debate has heated up since the Federal Reserve Bank announced that it was embarking on a second round of quantitative easing: a policy likely to drive down the exchange rate of the US dollar.
Writing in the Financial Times, Robert Zoellick, president of the World Bank, argues that co-ordinated global action needs to be taken to promote economic growth and stability. Amongst other things, this should include using gold as an ‘international reference point’.
“… the G20 should complement this growth recovery programme with a plan to build a co-operative monetary system that reflects emerging economic conditions. This new system is likely to need to involve the dollar, the euro, the yen, the pound and a renminbi that moves towards internationalisation and then an open capital account.
The system should also consider employing gold as an international reference point of market expectations about inflation, deflation and future currency values. Although textbooks may view gold as the old money, markets are using gold as an alternative monetary asset today.”
Would this be a return to the adjustable peg system designed at Bretton Woods in 1944 – a system that collapsed in the early 1970s? Zoellick thinks that the world should begin moving back to some sort of Bretton Woods system, with gold as the anchor against which currencies are pegged. Critics argue that this could be dangerously deflationary as the supply of gold is not something that can easily be increased. Read the articles below and consider whether such a move would be a good idea.
