In a speech in Dublin on 28 January 2015, titled ‘Fortune favours the bold‘, Mark Carney, the Governor of the Bank of England, compared the UK economy to that of the 19-nation eurozone. While he welcomed the ECB’s recently announced quantitative easing programme, he argued that the current construction of the eurozone is unfinished and still has two fundamental weaknesses that have not been addressed.
The first is the fragmented nature of banking:
With limited cross-border banking in the euro area, savings don’t flow to potential investments. Euro-area corporates’ cash balances have risen to the tune of €420 billion, or 3% of GDP, since the crisis, for example. Modest cross-border equity flows mean inadequate risk sharing.
The second is the lack of an integrated fiscal policy.
For complete solutions to both current and potential future problems, the sharing of fiscal risks is required.
It is no coincidence that effective currency unions tend to have centralised fiscal authorities whose spending is a sizeable share of GDP – averaging over a quarter of GDP for advanced countries outside the euro area.
… If the eurozone were a country, fiscal policy would be substantially more supportive. However, it is tighter than in the UK, even though Europe still lacks other effective risk sharing mechanisms
and is relatively inflexible. A more constructive fiscal policy would help recycle surplus private savings and mitigate the tail risk of stagnation. It would also bridge the drag from structural reforms on nominal spending and would be consistent with the longer term direction of travel towards greater integration.
But fiscal integration requires a political will to transfer fiscal surpluses from the stronger countries, such as Germany, to the weaker countries, such as those in southern Europe.
Overall, the financial and fiscal position in the eurozone is strong:
Gross general government debt in the euro area is roughly the same as in the UK and below the average of advanced economies. The weighted average yield on 10-year euro area sovereign debt is around 1%, compared to 1½% in the UK. And yet, the euro area’s fiscal deficit is half that in the UK. Its structural deficit, according to the IMF, is less than one third as large.
But, unlike the UK, where, despite the rhetoric of austerity, automatic fiscal stabilisers have been allowed to work and the government has accepted a much slower than planned reduction in the deficit, in the eurozone fiscal policy remains tight. Yet unemployment, at 11½%, is twice the rate in the UK and economic growth, at around 0.7% is only one-quarter of that in the UK.
Without a eurozone-wide fiscal policy the problem of slow growth is likely to persist for some time. Monetary policy in the form of QE will help and structural reforms will help to stimulate potential output and long-term growth, but these policies could be much more effective if backed up by fiscal policy.
Whether they will be any time soon is a political question.

Questions
- Compare the financial and fiscal positions of the UK and the eurozone.
- In what way is there a ‘debt trap’ in the eurozone?
- What did Mark Carney mean when he said, ‘Cross-border risk-sharing through the financial system has slid backwards.’?
- What options are there for the eurozone sharing fiscal risks?
- What would a ‘more constructive’ fiscal policy, as advocated by Mark Carney, look like?
- How do the fiscal policies of other currency unions, such as the UK (union of the four nations of the UK) or the USA (union of the 50 states) or Canada (union of the 10 provinces and three territories), differ from that of the eurozone?
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.
