The UK is an island-economy. Therefore, trade is a crucial determinant of our economic performance. The competitiveness of our exports, in part, is affected by the exchange rate. Floating exchange rates are notoriously volatile. However, since the autumn of 2007 we have observed a significant depreciation of the UK exchange rate. In other words the number of units of many foreign currencies to the British pound has fallen. A depreciation helps to make our exports more competitive abroad. We detail the extent of this depreciation and any signs of a reversal in this pattern.
Rather than look at the British pound (or any currency) against the many foreign currencies separately we can look at the average exchange rate against a whole bundle of currencies. The average rate is calculated by weighting the individual exchange rates by the amount of trade between Britain and the other countries. This trade-weighted exchange rate is known as the effective exchange rate.
In analysing the competitiveness of the exchange rate, we can go one step further and adjust for the terms of trade. This means that we adjust for the average price of our exports relative to the average price of those goods we import. Therefore, as well as the nominal (actual) effective exchange rate we can calculate a real effective exchange rate. If the average price of our exports rises relative to the average price of imports, the real effective exchange rate rises relative to the nominal rate. It means that we are able to obtain a larger volume of imports from selling a given volume of exports.
The chart shows the nominal (actual) and real effective exchange rate for the British pound since 2002. The chart shows clearly how from the autumn of 2007 the effective exchange rate both in nominal and real terms began to fall sharply. Over the period from September 2007 to January 2009 the nominal effective exchange rate fell by 26 per cent. After adjusting for the relative price of exports to imports, we find the real effective exchange rate fell by 24 per cent. In other words, the British pound depreciated by close to one-quarter in just 16 months.
If we move the clock forward, we observe a mild appreciation of the British pound since July 2011. In nominal terms, the effective exchange rate has appreciated by 6.8 per cent while in real terms it has appreciated by 7.8 per cent. Nonetheless, if we compare September 2007 with October 2012, we find that the nominal effective exchange rate for the British pound is 19 per cent lower while the real effective exchange rate is approximately 13 per cent lower. This still constitutes a major competitive boost for our exporters.

Paul Volcker was Chair of the US Federal Reserve from 1979 to 1987. He was also Chair of the Economic Recovery Advisory Board under President Barack Obama from February 2009 to January 2011. In the webcast and articles below, he reflects on the current state of the world financial system – from regulation, to the euro crisis, to world imbalances, to the system of floating exchange rates.
He argues that global financial systems are vulnerable to breakdowns. What is needed is reform to the system, and for that there needs to be consensus by politicians, regulators and central banks.
But, in the absence of international consensus on some key points, reform will be greatly weakened, if not aborted. The freedom of money, financial markets and people to move – and thus to escape regulation and taxation – might be an acceptable, even constructive, brake on excessive official intervention, but not if a deregulatory race to the bottom prevents adoption of needed ethical and prudential standards.
Perhaps most important is a coherent, consistent approach to dealing with the imminent failure of “systemically important” institutions. Taxpayers and governments alike are tired of bailing out creditors for fear of the destructive contagious effects of failure – even as bailouts encourage excessive risk-taking.
According to Volcker, countries must be prepared to surrender some sovereignty. Policies must be co-ordinated internationally and there must be stronger regulation by international bodies, such as the IMF and stronger concerted action by global organisations, such as the G20.
Left to their own devices, in an era of floating exchange rates, countries may pursue policies that exacerbate global imbalances.
Not so long ago, we were comforted by theorising that floating exchange rates would mediate international adjustments in a timely and orderly way. But, in the real world, many countries, particularly but not limited to small, open economies, simply find it impractical or undesirable to permit their currency to float.
We are left with the certainty, however awkward, that active participation in an open world economy requires some surrender of economic sovereignty. Or, to put the point more positively, it requires a willingness to co-ordinate policies more effectively.

Germany is the world’s fourth largest economy and Europe’s largest. Part of its strength has come from its exports, which last year increased by 11.4% to $1.3 trillion – the first time it had ever exceed the $1 trillion mark. Germany, however, is by no means the country with the largest export sector – that mantle was taken from them by China, whose exports rose 20.3% last year to reach $1.9 trillion.
At the same time as exports have been rising from Germany, imports have also increased, showing a recovery in domestic demand as well. Despite this, Germany’s foreign trade surplus increased slightly to €158.1 billion (from €154.9 billion).
However, in the last month of 2011, its export growth did slow – the fastest drop in nearly 3 years – and that is expected to signal the trend for 2012. As the eurozone debt crisis continues to cause problems, German exports have been forecast to grow by only 2% this year, with economic growth expected to be as low as 0.7%. This is a marked change from last year, where the Germany economy grew by some 3%. Help for the eurozone is unlikely to come form Europe’s second largest economy, France, where growth in the first 3 months of 2012 is expected to be zero and figures have shown a widening trade deficit, with issues of competitiveness at the forefront. The following articles look at Germany’s prowess in the export market and the likely developments over the coming year.

The International Monetary Fund consists of 187 countries and is concerned with its members’ economic health. It promotes co-operation, economic stability and is also there to lend to those countries facing difficulties. The role of the IMF as a lender has come into question, as critics argue that the conditions placed on loans to countries can cause more problems than they solve, as the cause of the problems is not always identified. However, despite the criticisms and the current charges facing the former IMF Chief, the International Monetary Fund continues to play an important role in the global economic environment.
Many countries have used IMF credit and over the past two decades it has predominantly been the transition and the emerging market economies that have demanded the IMF’s resources. Whilst its lending did drop off in the mid 2000s, the global financial crisis of 2008/09 saw an increase in the demand for IMF funds from emerging economies to some $60 billion. In May 2010, we saw the IMF together with the EU put together a rescue package for Greece and it is now the turn of Egypt. The uprisings in Egypt put the stability of the economy in jeopardy, as investment declined, tax revenues decreased and the usually buoyant tourist industry started to struggle. Despite the efforts of the government to stabilise the economy, it remains short of cash and the IMF looks set to agree a loan deal of $3 billion (£1.8 billion). Egypt would have five years to repay the loan at an interest rate of 1.5%, after a three year ‘grace period’.
Other countries to receive loans include Ireland, Belarus, the Ukraine and Iceland, the latter of which owes the IMF $2,828.67 per person of its population. The UK has used the IMF back in 1976 and it may be something to look out for, depending on how our recovery continues. The following articles look at the IMF and its role in promoting global financial stability.

Periodically, the BBC hosts debates on major global topics. The following links are to the January 2011 debate on the state of the world economy and on what policies governments and central banks should pursue.
Should governments be boosting aggregate demand by raising government expenditure and cutting taxes in order to stimulate growth and plan to bring down deficits over the long term once growth is established? Or should they embark on tough fiscal consolidation now by cutting government expenditure and/or raising taxes in order to stimulate confidence by international financiers, thereby keeping long-term interest rates down and creating the foundations for sustainable economic growth? The debate considers these two very different policy approaches.
The participants in the debate are Joseph Stiglitz (Professor of Economics, Columbia University), Christina Romer (Professor of Economics, University of California, Berkeley and Adviser to Barack Obama (2009–10)), George Papaconstantinou (Finance Minister of Greece), Dominique Strauss-Khan (Managing Director, IMF) and Zhou Xiaochuan (Governor, Chinese Central Bank). The debate is in five separate webcasts.
