On 20 February, the UK Prime Minister, David Cameron, announced the date for the referendum on whether the UK should remain in or leave the EU. It will be on 23 June. The announcement followed a deal with EU leaders over terms of UK membership of the EU. He will argue strongly in favour of staying in the EU, supported by many in his cabinet – but not all.
Two days later, Boris Johnson, the Mayor of London, said that he would be campaigning for the UK to leave the EU.
In the meantime, Mr Johnson’s announcement, the stance of various politicians and predictions of the outcome of the referendum are having effects on markets.
One such effect is on the foreign exchange market. As the Telegraph article below states:
The pound suffered its biggest drop against the dollar in seven years after London Mayor Boris Johnson said he will campaign for Britain to leave the European Union [‘Brexit’].
Sterling fell by as much as 2.12pc to $1.4101 against the dollar on Monday afternoon, putting it on course for the biggest one day drop since February 2009. Experts said the influential Mayor’s decision made a British exit from the bloc more likely.

The pound also fell by as much as 1.2pc to €1.2786 against the euro and hit a two-year low against Japan’s yen.
This follows depreciation that has already taken place this year as predictions of possible Brexit have grown. The chart shows that from the start of the year to 23 February the sterling trade weighted index fell by 5.3% (click here for a PowerPoint).
But why has sterling depreciated so rapidly? How does this reflect people’s concerns about the effect of Brexit on the balance of payments and business more generally? Read the articles and try answering the questions below.

Are emerging markets about to experience a credit crunch? Slowing growth in China and other emerging market economies (EMEs) does not bode well. Nor does the prospect of rising interest rates in the USA and the resulting increase in the costs of servicing the high levels of dollar-denominated debt in many such countries.
According to the Bank for International Settlements (BIS) (see also), the stock of dollar-denominated debt in emerging market economies has doubled since 2009 and this makes them vulnerable to tighter US monetary policy.
Weaker financial market conditions combined with an increased sensitivity to US rates may heighten the risk of negative spillovers to EMEs when US policy is normalised. …
Despite low interest rates, rising debt levels have pushed debt service ratios for households and firms above their long-run averages, particularly since 2013, signalling increased risks of financial crises in EMEs.
But there is another perspective. Many emerging economies are pursuing looser monetary policy and this, combined with tighter US monetary policy, is causing their exchange rates against the dollar to depreciate, thereby increasing their export competitiveness. At the same time, more rapid growth in the USA and some EU countries, should also help to stimulate demand for their exports.
Also, in recent years there has been a large growth in trade between emerging economies – so-called ‘South–South trade’. Exports from developing countries to other developing countries has grown from 38% of developing countries’ exports in 1995 to over 52% in 2015. With technological catch-up taking place in many of these economies and with lower labour and land costs, their prospects look bright for economic growth over the longer term.
These two different perspectives are taken in the following two articles from the Telegraph. The first looks at the BIS’s analysis of growing debt and the possibility of a credit crunch. The second, while acknowledging the current weakness of many emerging economies, looks at the prospects for improving growth over the coming years.

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.

Newspaper headlines this week read that the UK’s balance of trade deficit has widened to £34.8bn, the largest since 2010. And when you exclude services, the trade in goods deficit, at £119.9bn is the largest ever in nominal terms and is also likely to be the largest as a percentage of GDP.
So far so bad. But when you look a little closer, the picture is more mixed. The balance of trade deficit (i.e. on both goods and services) narrowed each quarter of 2014, although the monthly figure did widen in December 2014. In fact the trade in goods deficit increased substantially in December from £9.3bn to £10.2bn.
At first sight the widening of the trade deficit in December might seem surprising, given the dramatic drop in oil prices. Surely, with demand for oil being relatively inelastic, a large cut in oil prices should significantly reduce the expenditure on oil? In fact the reverse happened. The oil deficit in December increased from £598m to £940m. The reason is that oil importing companies have been stockpiling oil while low prices persist. Clearly, this is in anticipation that oil prices will rise again before too long. What we have seen, therefore, is a demand that is elastic in the short run, even though it is relatively inelastic in the medium run.
But the trade deficit is still large. Even when you strip out oil, the deficit in December still rose – from £8.7bn to £9.2bn. There are two main reasons for this deterioration.
The first is a strong pound. The sterling exchange rate index rose by 1.8% in December and a further 0.4% in January. With quantitative easing pushing down the value of the euro and loose monetary policies in China and Australia pushing down the value of their currencies, sterling is set to appreciate further.
The second is continuing weakness in the eurozone and a slowing of growth in some major developing countries, including China. This will continue to dampen the growth in UK exports.
But what of the overall current account? Figures are at present available only up to 2014 Q3, but the picture is bleak (see the chart). As the ONS states:
The current account deficit widened in Q3 2014, to 6.0% of nominal Gross Domestic Product GDP, representing the joint largest deficit since Office for National Statistics (ONS) records began in 1955.
This deterioration in performance can be partly attributed to the recent weakness in the primary income balance [see]. This also reached a record deficit in Q3 2014 of 2.8% of nominal GDP; a figure that can be primarily attributed to a fall in UK residents’ earnings from investment abroad, and broadly stable foreign resident earnings on their investments in the UK
The primary income account captures income flows into and out of the UK economy, as opposed to current transfers (secondary income) from taxes, grants, etc. The large deficit reflects a decline in the holding by UK residents of foreign assets from 92% of GDP in 2008 to 67% by the end of 2014. This, in turn, reflects the poorer rate of return on many of these assets. By contrast, the holdings of UK assets by foreign residents has increased. They have been earning a higher rate of return on these assets than UK residents have on foreign assets. And so, despite UK interest rates having fallen, as the quote above says, foreign residents’ earnings on their holding of UK assets has remained broadly stable.

One effect of an expansionary monetary policy is a depreciation of the exchange rate. Take the case of countries using a combination of a reduction in central bank interest rates and quantitative easing (QE). A fall in interest rates will encourage an outflow of finance; and part of the money created through quantitative easing will be used to purchase foreign assets. Both create an increased demand for foreign currencies and drive down the exchange rate.
The latest case of expansionary monetary policy is that employed by the ECB. After months of promising to ‘do whatever it takes’ and taking various steps towards full QE, the ECB finally announced a large-scale QE programme on 22 January 2015.
With people increasingly predicting QE and with the ECB reducing interest rates, so the euro depreciated. Between March 2014 and 21 January 2015, the euro depreciated by 20.2% against the dollar and the euro exchange rate index depreciated by 9.7%. With the announced programme of QE being somewhat larger than markets expected, in the week following the announcement the euro fell a further 2.3% against the dollar, and the euro exchange rate index also fell by 2.3%. The euro is now at its lowest level against the US dollar since April 2003 (see chart).
The depreciation of the euro will be welcome news for eurozone exporters. It makes their exports cheaper in foreign currency terms and thus makes their exports more competitive.
Similarly Japanese exporters were helped by the depreciation of the yen following the announcement on 31 October 2014 by the Bank of Japan of an increase in its own QE programme. The yen has depreciated by 7.7% against the dollar since then.
But every currency cannot depreciate against other currencies simultaneously. With any bilateral exchange rate, the depreciation of one currency represents an appreciation of the other. So just as the euro and yen have depreciated against the dollar, the dollar has appreciated against the euro and yen. This has made US goods less competitive relative to eurozone and Japanese goods.
The danger is that currency wars will result, with monetary policy being used in various countries to achieve competitive depreciations. Already, the Swiss have been forced, on 15 January, to remove the cap with the euro at SF1 – €0.833. Since then the Swiss franc has appreciated by some 15% to around SF1 – €0.96. Will the Swiss now be forced to relax their monetary policy?
The Danish and Canadian central banks have cut their interest rates, hoping to stem an appreciation of their currencies. On 28 January, the Monetary Authority of Singapore sold Singapore dollars to engineer a depreciation. The Singapore dollar duly fell by the most in over four years.
But are these policies simply beggar-my-neighbour policies? Is it a zero-sum game, where the gains to the countries with depreciating currencies are exactly offset by losses to the those with appreciating ones? Or is there a net gain from overall looser monetary policy at a time of sluggish growth? Or is there a net loss from greater currency volatility, which will create greater uncertainty and dampen cross-border investment? The following article explore the issues.
