The exchange rate for sterling is determined in much the same way as the price of goods – by the interaction of demand and supply.
When factors change that cause residents abroad to want to hold more or fewer pounds, the demand curve for sterling will shift. If, instead, factors change that cause UK residents to want to buy more or less foreign currency, then the supply curve of sterling will shift. It is these two curves that determine the equilibrium exchange rate of sterling.
There are concerns at the moment that sterling is about to reach a peak, with expectations that the pound will weaken throughout 2013. But is a weakening exchange rate good or bad for the UK?
With lower exchange rates, exports become relatively more competitive. This should lead to an increase in the demand for UK products from abroad. As exports are a component of aggregate demand, any increase in exports will lead to the AD curve shifting to the right and thus help to stimulate a growth in national output. Indeed, throughout the financial crisis, the value of the pound did fall (see chart above: click here for a PowerPoint) and this led to the total value of UK exports increasing significantly. However, the volume of UK exports actually fell. This suggests that whilst UK exporters gained in terms of profitability, they have not seen much of an increase in their overall sales and hence their market share.
Therefore, while UK exporters may gain from a low exchange rate, what does it mean for UK consumers? If a low exchange rate cuts the prices of UK goods abroad, it will do the opposite for the prices of imported goods in the UK. Many goods that UK consumers buy are from abroad and, with a weak pound, foreign prices become relatively higher. This means that the living standards of UK consumers will be adversely affected by a weak pound, as any imported goods buy will now cost more.
It’s not just the UK that is facing questions over its exchange rate. Jean-Claude Junker described the euro as being ‘dangerously high’ and suggested that the strength or over-valuation of the exchange rate was holding the eurozone back from economic recovery. So far the ECB hasn’t done anything to steer its currency, despite many other countries, including Japan and Norway having already taken action to bring their currencies down. Mario Draghi, the ECB’s president, however, said that ‘both the real and the effective exchange rate of the euro are at their long-term average’ and thus the current value of the euro is not a major cause for concern.
So, whatever your view about intervening in the market to steer your currency, there will be winners and losers. Now that countries are so interdependent, any changes in the exchange rate will have huge implications for countries across the world. Perhaps this is why forecasting currency fluctuations can be so challenging. The following articles consider changes in the exchange rate and the impact this might have.

Trade is generally argued to be good for economic growth, as it allows countries to specialise in those goods in which they have a comparative advantage and thus produce and consume more of all goods in total. However, trade inevitably leads to winners and losers, especially as countries impose tariffs on imports in order to protect domestic industries. This has been the case in the banana industry.
Banana growers in the former European colonies have long been protected by EU tariffs, helping to prevent competition from their Latin American banana growers. But, now things could be about to change. In December 2009, most of the nations concerned reached an agreement in Geneva for tariffs imposed by the EU to be gradually reduced.
The European Union had imposed no duty on bananas from their former colonies, but had imposed tariffs on banana imports from other countries. This meant that those countries now benefiting from zero import duty could sell their bananas for a much lower price, therefore restricting the other nations (who did have to pay an import duty) from competing effectively.
With the World Trade Organisation in attendance, an agreement was signed that puts an end to this trade dispute dating back over 2 decades. The Director General of the WTO, Pascal Lamy said:
‘This is a truly historic moment … After so many twists and turns, these complicated and politically contentious disputes can finally be put to bed. It has taken so long that quite a few people who worked on the cases, both in the Secretariat and in member governments have retired long ago.’
This trade war has been ongoing for many years and this agreement represents a big step in the right direction. With a fairer playing field in this banana market, countries in Latin America will now be much more able to compete with other nations. As economists argue that trade is good, a reduction in protectionist measures should be seen as a good thing and will benefit the countries concerned. The following articles consider this trade resolution.

China has been one of the success stories of the past 20 years, with rapid growth in domestic and export demand. This has created the second largest economy in the world. From 1992 to 2007 annual GDP growth averaged 10.7% and annual export growth averaged 18.9% (see chart).
However, with the credit crunch and ensuing recession, growth rates in China have fallen somewhat. Annual GDP growth has averaged 9.6% and annual export growth has averaged 7.4%. Such growth rates may not seem bad, given that many Western economies have been struggling to achieve any growth, but they have been causing concern for this booming economy.
In its May Outlook, the World Bank forecast China’s growth for the year at 8.2%, but it has since been reduced to 7.8%. A key part of China’s success story has been its export market, but it has been this market that has caused concerns for the mainland economy. In August of this year, its year-on-year export growth was at only 2.7%, but exports last month grew by more than expected, at approximately 7.4%. China has had a consistent trade surplus and according to government figures, this has widened to $27.67 billion in September from $26.66 billion in the previous month.
Recovery in this market will be crucial for the continued success of the economy, as a means of alleviating the fears of a slowdown. This higher growth of exports may be a misleading indicator, perhaps influenced by seasonal factors and thus may not be a sign of what’s to come. Indeed, many analysts have said that they are not convinced that these healthier trade figures will remain. Alistair Thornton, from IHS Global Economics said:
“It’s safe to say we are overshooting the trend here and we expect (the data) to come back in line in the months ahead.”
Citigroup economist, Ding Shaung also confirmed these sentiments:
”The trade data is a positive sign for the Chinese economy … But it remains to be seen whether import and export growth can remain at these levels.”
Part of this pessimism is due to the uncertainty surrounding the growth prospects of its biggest two trading partners – the US and the European Union. Exports to the former have remained relatively high, but exports to the European Union have suffered, falling by over 5.6%. It is likely that weaknesses in the global economy have held back China’s growth prospects in both exports and national output. The Chinese government was aiming for growth of 7.6% in 2012. Not a bad rate you may say, but when compared with growth rates for 2011 (9.3%) and 2010 (10.4%), it does represent a significant fall. The future of the Chinese economy is crucial for the recovery of the world economy, in part as it represents a big demand for imports from other countries, such as the US and Europe. The following articles consider the trade and growth prospects of the world’s second largest economy.

International economists have long advocated the advantages of free trade. By boosting competition, increasing choice and market size, trade has long been seen as an engine of growth and efficiency.
For many years, tariffs and other restrictive trade practices have been removed on trade between both developed and developing countries and many rounds of negotiations have taken place, with mixed results.
The World Trade Organisation (WTO) plays a key role in trade negotiations and has the main aim of liberalising trade. The organisation requires its members to operate according to a variety of rules, including the prohibition of quotas and the inability of countries to raise existing tariffs without negotiating with their trading partners.
If any country breaks a trade agreement, the WTO can impose sanctions. A current case that has been referred to the WTO for ‘consultation’ concerns Argentina. Argentina has imposed various import restrictions on trade, such as import licensing and a requirement for countries to balance its exports and imports.
A number of WTO members recently expressed their concerns about these restrictive trade practices. The EU trade commissioner Karel de Gucht said:
Argentina’s import restrictions violate international trade rules and must be removed. These measures are causing very real damage to EU companies – hurting jobs and our economy as a whole. … Argentina’s trade policy has become rooted in unfair trade practices.
Argentina has said that it was expecting the move from the EU, but claims that its protectionist measures are there to support and re-industrialise the country. This case is unlikely to be resolved any time soon and while the ‘restrictive trade practices’ remain in place, EU companies trying to export to Argentina will find barriers, such as a requirement for all imports to receive pre-approval.
The effects of these restrictions have already been felt, with EU exports to Argentina down by 4% in April this year, compared with the same month last year. The following articles consider this issue.

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.
