The best currency for an independent Scotland would be Norway’s kronor

If Scotland votes for independence, it will create a completely different economic context for the two new countries that emerge.

Scotland’s referendum debate has so far centred mainly on practical issues and medium-term choices like currency, new entities' share of public debt, and membership of the EU.

Far less has been said about how the different players influenced by the outcome will be affected in the longer term. It is well worth considering how independence would eventually affect the Scottish and UK economies, particularly in relation to North Sea oil. The reality is that this constitutional change could alter the macroeconomic foundations of the political map of Europe.

Aside from the UK, Norway and Denmark are the two other countries which now explore the North Sea. In 2013 the total proportions of North Sea oil produced by these three countries were 27%, 66% and 7% of the total respectively. By my estimates, Denmark’s oil sector provided around 5% of the country’s GDP, once you include petroleum production and dependent industries such as petroleum services, pipelines, refineries and so forth. For the UK it was somewhere approaching 20%, while for Norway it was 23%.

Oil and European integration

There is a strong correlation between these oil sector figures and each country’s economic and political choices. Norway stays out of both the EU and European monetary union. It has its own independent currency, whose rate of exchange is determined by the market.

At the other end of the spectrum Denmark is a member of the EU and is part of European Exchange Mechanism II (ERM II). The Danish krone’s exchange rate is tied to the euro, making it practically another form of euro. The UK is in the middle: a member of the EU but not in ERM II or the euro.

If Scotland votes for independence, it will create a completely different economic context for the two new countries that emerge. This new macroeconomic framework will work against the currently declared goals of both countries' governments.

The economy of an independent Scotland would of course be much smaller than the economy of the new UK. This means that with the same absolute oil extraction, you can estimate that the sector would contribute more than one-third of Scotland’s GDP. In the new smaller UK, on the other hand, it would only contribute something like 1% (coming from the mainly gas fields off east England).

Future choices for Scotland and the UK

This suggests that it would suit the two countries to make completely different economic and political choices. If North Sea oil dominates the Scottish economy to an even greater degree than in the case of Norway, it would suggest that it would be even less inclined towards the EU and euro than the latter country.

The logic behind this point is that oil changes the economic cycle of a country. The easiest way to think about this is to reflect on the effect of the oil price. If the oil price is high, a country that heavily relies on oil production does well and non-producers tend to do less well, because they are paying higher prices for their fuel. When oil prices are low, this reverses.

Anyone who had a passing interest in the eurozone crisis will know that the problems between the Mediterranean periphery countries and their northern neighbours were partly caused by the fact that they needed different levels of interest rates to suit their economies. An independent Scotland would suffer a similar fate, albeit for different reasons. The more that oil dominates an economy, the less well suited it is to European integration.

For the same reason, the rest of the UK would be inclined much more towards these European institutions than beforehand. The Danish experience suggests that it might lead not only to membership of ERM II but also even to adoption of the euro.

In turn, this would also lead to changes in the EU. The sheer size of the new UK would enhance the core of EU international member states, greatly increasing GDP for example. At the same time, the relative strength of socialist-inclined France would be reduced, raising the prospect of a more Atlanticist free-market approach to European unification.

On the other hand, Scotland and Norway would be naturally pushed closer to each other. They might be joined by Sweden and Iceland – Iceland and Norway share fishing interests, while Sweden and Norway’s economies are closely aligned. This could lead to much closer political co-operation between these countries, plus a kind of monetary co-ordination, if not monetary union.

Some might dismiss these arguments, pointing out that Scotland has aspirations towards the EU and that England is increasingly eurosceptic. But such people should remember the example of the UK’s brief membership in the first European Exchange Mechanism in 1990-91. The lesson was that no matter the political will, the economics will be fundamental in determining how situation evolves.

In view of these observations, it is hard not to reach several final conclusions. The Scots are not making a choice in September that is fully informed in economic terms. And the UK and EU do not seem to be fully aware of the possible long-term consequences either.

There are risks as well as opportunities ahead for George Osborne

The Chancellor is in a tight spot, but expect his political wiles to be on full display, says Spencer Thompson.

The most significant fiscal event of this parliament will take place in late November, when the Chancellor presents the spending review setting out his plans for funding government departments over the next four years. This week, across Whitehall and up and down the country, ministers, lobbyists, advocacy groups and town halls are busily finalising their pitches ahead of Friday’s deadline for submissions to the review

It is difficult to overstate the challenge faced by the Chancellor. Under his current spending forecast and planned protections for the NHS, schools, defence and international aid spending, other areas of government will need to be cut by 16.4 per cent in real terms between 2015/16 and 2019/20. Focusing on services spending outside of protected areas, the cumulative cut will reach 26.5 per cent. Despite this, the Chancellor nonetheless has significant room for manoeuvre.

Firstly, under plans unveiled at the budget, the government intends to expand capital investment significantly in both 2018-19 and 2019-20. Over the last parliament capital spending was cut by around a quarter, but between now and 2019-20 it will grow by almost 20 per cent. How this growth in spending should be distributed across departments and between investment projects should be at the heart of the spending review.

In a paper published on Monday, we highlighted three urgent priorities for any additional capital spending: re-balancing transport investment away from London and the greater South East towards the North of England, a £2bn per year boost in public spending on housebuilding, and £1bn of extra investment per year in energy efficiency improvements for fuel-poor households.

Secondly, despite the tough fiscal environment, the Chancellor has the scope to fund a range of areas of policy in dire need of extra resources. These include social care, where rising costs at a time of falling resources are set to generate a severe funding squeeze for local government, 16-19 education, where many 6th-form and FE colleges are at risk of great financial difficulty, and funding a guaranteed paid job for young people in long-term unemployment. Our paper suggests a range of options for how to put these and other areas of policy on a sustainable funding footing.

There is a political angle to this as well. The Conservatives are keen to be seen as a party representing all working people, as shown by the "blue-collar Conservatism" agenda. In addition, the spending review offers the Conservative party the opportunity to return to ‘Compassionate Conservatism’ as a going concern.  If they are truly serious about being seen in this light, this should be reflected in a social investment agenda pursued through the spending review that promotes employment and secures a future for public services outside the NHS and schools.

This will come at a cost, however. In our paper, we show how the Chancellor could fund our package of proposed policies without increasing the pain on other areas of government, while remaining consistent with the government’s fiscal rules that require him to reach a surplus on overall government borrowing by 2019-20. We do not agree that the Government needs to reach a surplus in that year. But given this target wont be scrapped ahead of the spending review, we suggest that he should target a slightly lower surplus in 2019/20 of £7bn, with the deficit the year before being £2bn higher. In addition, we propose several revenue-raising measures in line with recent government tax policy that together would unlock an additional £5bn of resource for government departments.

Make no mistake, this will be a tough settlement for government departments and for public services. But the Chancellor does have a range of options open as he plans the upcoming spending review. Expect his reputation as a highly political Chancellor to be on full display.
