With countries around the globe struggling to recover from recession, many seem to believe that the answer lies in a growth in exports. But how can this be achieved? A simple solution is to lower the exchange rate.
Under a pegged exchange rate, the currency could be devalued. Alternatively, if the country’s inflation is lower than that of other countries, merely leaving the exchange rate pegged at its current level will bring about a real devaluation (in purchasing-power parity terms).
Under a floating exchange rate, one answer would be to lower interest rates. This would involve open market operations to support the lower rate and that would increase the money supply. But with central banks’ interest rates at virtually zero, it is not possible to lower them further. In such circumstances a solution would be a deliberate policy of increasing the money supply through “quantitative easing”. For example, the USA is considering a second round of quantitative easing (known as “QE2”). This would tend to push down the exchange rate of the dollar.
But stimulating exports through devaluation or depreciation is a zero-sum game globally. If currency A depreciates against currency B, currency B necessarily appreciates against currency A. Country A’s gain in exports to Country B are an increase in imports for Country B. It is logically impossible for every currency in the world to depreciate! Yet depreciation is exactly the policy being pursued by countries such as Japan, South Korea and Taiwan, all of which have directly intervened in the currency markets to lower their exchange rates. And, in each case of course, other countries’ currencies have an equivalent appreciation against them.
Economists and politicians in the USA argue that the dollar is fundamentally over valued against the Chinese yuan (or ‘renminbi’ as it is sometimes called). They are calling on China to revalue by far more than the 2% increase since June 2010. But what if China refuses to do so? On 29 September the House of Representatives passed a bill giving the executive branch the authority to impose a wide range of tariffs on imports from China. The bill was passed with a huge majority of 348 to 79.
So is this the start of a trade war? Many in the USA argue that China is already waging such a war by giving subsidies to a wide range of exports. And that war is hotting up. China has just announced that it is imposing traiffs ranging from 50% to 104% on various poultry imports from the USA. And if it is a trade war, will there be any winners?

- Do a search on “Smoot-Hawley Tariff Act” of 1930 and describe its impact on the global economy in the 1930s. Are there any parallels today?
- How is it possible for massive trade surpluses and deficits to persist and yet for individual countries’ exchange rates and overall balance of payments to be in equilibrium?
- Are global trade imbalances widening, and if so why?
- What would determine the size of the effect on the US balance of trade of an appreciation of the yuan?
For the past three years the Japanese yen has been appreciating against the US dollar and many other currencies. From the end of June 2007 to 14 September 2010, the yen appreciated from ¥100 = $0.81 to ¥100 = $1.20 (a 48% appreciation). Over the same period the yen exchange rate index rose from 113.3 to 172.4 (a 52% appreciation). The rising yen has been impeding Japan’s recovery as it has made its exports more expensive, while, at the same time, making imports cheaper and thus making it harder for domestic firms to compete.
Until 14 September 2010, the yen was freely floating. But on 15 September, the Japanese central bank decided to intervene by selling yen and buying dollars and other currencies.
But why had the yen risen so strongly? There are four main reasons.
The first is the persistent Japanese trade surpluses, partly stimulated by falling costs of production in Japan.
The second is the unwinding of the carry trade. Before the banking crisis of 2007/8, many banks and other financial institutions borrowed yen, given the low interest rates in Japan, and used the yen to purchase dollars and pounds, given the much higher interest rates in the USA and the UK. The effect of this ‘carry trade’, as it was known, was to drive up the exchange rates of the dollar and sterling and drive down the value of the yen. This encouraged further speculation as people sold yen in anticipation of further depreciation and purchased dollars and sterling in anticipation of further appreciation. With the banking crisis, however, short-term financial flows decreased and the current account became more important in determining exchange rates. The carry trade began to unwind and people began selling dollars and sterling and buying yen. What is more, towards the end of 2008, interest rates were reduced substantially in the USA and the UK in order to stimulate aggregate demand. The interest rate differential between Japan and the USA and UK virtually disappeared. This further encouraged the purchase of yen and the sale of dollars and sterling as carry trade investors began paying back their loans to Japan.The third reason for the appreciation of the yen is the actions of the Chinese who have used their surpluses to buy other currencies: originally mainly dollars, but increasingly yen.
The fourth reason is speculation. As the yen has risen, so increasingly people have bought yen in anticipation of further appreciation. But, of course, this speculation has brought about the very effect the speculators anticipated. Such speculation can be very powerful, given that some $4 trillion goes across the foreign exchange markets every day (see The inexorable growth of FOREX).
So will the intervention by the Bank of Japan be successful in causing the yen to depreciate? Or will the forces that drove up the yen prove impossible to resist? The following articles consider this question and also look at the factors that caused the yen to appreciate and its effects on the Japanese economy.

Questions
- Why has the Japanese yen appreciated so much over the past three years?
- What will be the effect of the Bank of Japan’s exchange market intervention on Japanese money supply? What will determine the size of this effect?
- Why might the Bank of Japan’s actions have been influenced by the anticipation of further quantitative easing by the US Federal Reserve Bank?
- What factors determine the likely success of foreign exchange market intervention by central banks?
- What will determine how speculators will react to the Bank of Japan’s actions?
- Discuss the following quote from the second The Economist article above: “A bit of inflation in Japan wouldn’t just be a good thing. It would be a really, really great thing. And if other countries react to Japan’s intervention by attempting to print and sell their own currencies in order to toss the deflationary potato to someone else, well then so much the better.”
- If all countries seek to achieve export-led growth, is this a zero-sum game?
- Why has the price of gold been rising?
According to GDP figures released on 15 August, China overtook Japan in the second quarter of 2010 to become the world’s second largest economy. This raises two questions: just what do the GDP figures mean and why has this happened?
The GDP figures are total figures measured in US dollars at current exchange rates. According to these nominal figures, Japan’s GDP was $1.286 trillion in the second quarter of 2010; China’s was $1.335 trillion. This follows several years when Chinese growth rates have massively exceeded Japanese ones.
As far as explanations are concerned, economists look to a number of different factors, including investment policies, relative exchange rates, confidence, deflation in Japan and the scope for catching up in China.
The following podcasts and webcasts look at these questions, as do the articles.

The link below is to a podcast by Martin Wolf of the Financial Times. It considers a new book, Fault Lines by Raghu Rajan of the University of Chicago Booth School of Business. Rajan argues that the global economy is severely unbalanced:
There is a fair amount of consensus that the world economy is in need of rebalancing. Countries like Iceland, Greece, Spain, and the United States overspent prior to the crisis, financing the spending with government or private borrowing, while countries like Germany, Japan, and China supplied those countries goods even while financing their spending habits. Simply put, the consensus now requires U.S. households to save more and Chinese households to spend more in order to achieve the necessary rebalancing.
Martin Wolf identifies these imbalances and discusses various possible solutions. The problem is that what may seem sensible economically is not always feasible politically.

The east African countries of Kenya, Tanzania, Uganda, Burundi and Rwanda have been operating with a common external tariff for some time. The East African Community (EAC), as it is known, came into force in 2000. Initially it had just three members, Kenya, Tanzania and Uganda; the other two countries joined in 2007. As the Community’s site says:
The EAC aims at widening and deepening co-operation among the Partner States in, among others, political, economic and social fields for their mutual benefit. To this extent the EAC countries established a Customs Union in 2005 and are working towards the establishment of a Common Market in 2010, subsequently a Monetary Union by 2012 and ultimately a Political Federation of the East African States.
This Common Market came into force on 1 July 2010, with free movement of labour being instituted between the five countries. The plan is also to do away with all internal barriers to trade, although it may take up to five years before this is completed.
The following articles and videos look at this significant opening up of trade in east Africa and at people’s reactions to it. Will all five countries gain equally? Or will some gain at the others’ expense?
