In a speech in Edinburgh, Mark Carney, Governor of the Bank of England, considered the implications of Scotland retaining the pound if the Scottish people vote yes for independence. His speech was intended to be non-political. Rather he focused on two main questions: first whether a currency union of Scotland and the rest of the UK (RUK) would be an optimal currency area; second how much economic sovereignty would need to be shared with RUK as a consequence of Scotland keeping the pound.

On the first question, Mark Carney argued that the current UK is close to an optimal currency area as there is a high degree of economic integration and factor mobility. Sharing a currency eliminates exchange costs, improves pricing transparency and hence encourages competition, promotes cross-border investment, improves the flow of technology and ideas, and increases the mobility of labour and capital.

But sharing a currency involves sharing a monetary policy. This would still be determined by the Bank of England and would have to geared to the overall economic situation of the union, not the specific needs of Scotland.

There would also need to be a banking union, whereby banks in difficulties would receive support from the whole currency area. In Scotland’s case, banking accounts for a very large proportion of the economy (12.5% compared with 4.3% for RUK) and could potentially place disproportionate demands on the currency union’s finances.

And then there is the question of fiscal policy. A shared currency also means pooling a considerable amount of sovereignty over taxation, government spending and government debt. This could be a serious problem in the event of asymmetric shocks to Scotland and RUK. For example, if oil prices fell substantially, Scotland may want to pursue a more expansionary fiscal policy just at a time when its tax revenues were falling. This could put a strain on Scotland’s finances. This might then require RUK to provide support from a common pool of funds, such as a ‘regional fund’.

Being in a currency union can amplify fiscal stress, and increase both the risks and consequences of financial instability. In the situation just described [a fall in demand for exports], fiscal policy would ideally help smooth adjustment to the external shock. But its ability to do so could be limited by the budgetary impact of the falls in output, prices and wages. To maintain credibility, fiscal policy may even become pro-cyclical, with the resulting austerity exacerbating the initial fall in demand. In the extreme, adverse fiscal dynamics could call into question a country’s membership of the union, creating the possibility of self-fulfilling ‘runs’ on bank and sovereign debt absent central bank support.6 Such adverse feedback loops turned recessions into depressions in several European countries in recent years.

A separate Scottish currency, by contrast, would, according to Carney, be a valuable shock absorber if domestic wages and prices were sticky.

For example, suppose demand for a country’s exports falls. All else equal, its output will fall, unemployment increase and current account deteriorate. With an independent currency, exchange rate depreciation can dampen these effects by improving competitiveness, and monetary policy can become more accommodative, supporting demand and employment. However, if the country were part of a currency area with its foreign market, its exchange rate would by definition not change, putting the full weight of adjustment on wages and unemployment – a significantly more protracted and painful process. In addition, the responsiveness of monetary policy to weak demand in that country would be diluted by the needs of the broader membership.

But despite the problems of ceding a degree of monetary and fiscal sovereignty, Scotland and RUK are well placed to continue with a successful currency union if Scotland becomes independent. Economic conditions are very similar, as are language, culture and institutions, and there is an effective banking union – assuming such a banking union were to continue post independence.

The existing banking union between Scotland and the rest of the United Kingdom has proved durable and efficient. Its foundations include a single prudential supervisor maintaining consistent standards of resilience, a single deposit guarantee scheme backed by the central government, and a common central bank, able to act as Lender of Last Resort across the union, and also backed by the central government. These arrangements help ensure that Scotland can sustain a banking system whose collective balance sheet is substantially larger than its GDP.

The desirability of Scottish independence is a normative question for the Scottish electorate to decide. Nevertheless, economists have an important part to play in informing the debate. Mark Carney’s economic analysis of currency union if the Scottish electorate votes yes is a good example of this.

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.

From the end of January to the beginning of March, the sterling exchange rate index fell by over 6% – from 81.7 to 76.5. Against the dollar, the fall has been even more dramatic, falling from $1.62 to $1.49 (a fall of 8%). What are the reason for this? And is the depreciation likely to continue? The following clip looks at what has been going on and whether the reasons are political, or whether there are other economic fundamentals that have contributed to sterling’s fall.

The pound has been rising against the US dollar recently. And as the dollar has fallen, so the prices of various commodities, such as gold and silver, have been rising. So what are the reasons for these currency and commodity price movements? The simple answer is that they merely reflect changes in demand and supply. But why have demand and supply been changing? Are there changes in the underlying economic fundamentals, or do they largely reflect speculation in times of uncertainty and resulting market overcorrection? The following articles address these questions.
