The Brexit vote has caused shockwaves throughout European economies. But there is a potentially larger economic and political problem facing the EU and the eurozone more specifically. And that is the state of the Italian banking system and the Italian economy.

Italy is the third largest economy in the eurozone after Germany and France. Any serious economic weaknesses could have profound consequences for the rest of the eurozone and beyond.

At 135% of GDP, Italy’s public-sector debt is one the highest in the world; its banks are undercapitalised with a high proportion of bad debt; and it is still struggling to recover from the crisis of 2008–9. The Economist article elaborates:

The adult employment rate is lower than in any EU country bar Greece. The economy has been moribund for years, suffocated by over-regulation and feeble productivity. Amid stagnation and deflation, Italy’s banks are in deep trouble, burdened by some €360 billion of souring loans, the equivalent of a fifth of the country’s GDP. Collectively they have provisioned for only 45% of that amount. At best, Italy’s weak banks will throttle the country’s growth; at worst, some will go bust.

Since 2007, the economy has shrunk by 10%. And potential output has fallen too, as firms have closed. Unemployment is over 11%, with youth unemployment around 40%.

Things seem to be coming to a head. As confidence in the Italian banking system plummets, the Italian government would like to bail out the banks to try to restore confidence and encourage deposits and lending. But under new eurozone rules designed to protect taxpayers, it requires that the first line of support should be from bondholders. Such support is known as a ‘bail-in’.

If bondholders were large institutional investors, this might not be such a problem, but a significant proportion of bank bonds in Italy are held by small investors, encouraged to do so by tax relief. Bailing in the banks by requiring bondholders to bear significant losses in the value of their bonds could undermine the savings of many Italians and cause them severe hardship, especially those who had saved for their retirement.

So what is the solution? Italian banks need recapitalising to restore confidence and prevent a more serious crisis. However, there is limited scope for bailing in, unless small investors can be protected. And eurozone rules provide little scope for government funding for the banks. These rules should be relaxed under extreme circumstances. At the same time, policy needs to focus on making Italian banking more efficient.

Meanwhile, the IMF is forecasting that Italian economic growth will be less than 1% this year and little better in 2017. Part of the problem, claims the IMF, is the Brexit vote. This has heightened financial market volatility and increasead the risks for Italy with its fragile banking system. But the problems of the Italian economy run deeper and will require various supply-side policies to tackle low productivity, corruption, public-sector inefficiency and a financial system not fit for purpose. What the mix of these policies should be – whether market based or interventionist – is not just a question of effectiveness, but of political viability and democratic support.

Since the Brexit vote in the referendum, sterling has been falling. It is now at a 31-year low against the US dollar. From 23 June to 6 July it depreciated by 12.9% against the US dollar, 10.7% against the euro and 17.0% against the yen. The trade-weighted sterling exchange rate index depreciated by 11.6%.

Why has this happened? Partly it reflects a decline in confidence in the UK economy by investors; partly it is in response to policy measures, actual and anticipated, by the Bank of England.

As far as investors are concerned, the anticipation is that there will be net direct investment outflows from the UK. This is because some companies in the UK are considering relocating part or all of their business from the UK to elsewhere in Europe. For example, EasyJet is drawing up plans to move its headquarters to continental Europe. It is also because investors believe that foreign direct investment in the UK is likely to fall as companies prefer to invest elsewhere, such as Ireland or Germany.

Thus although the effect of net direct investment outflows (or reductions in net inflows) will be on the long-term investment part of the financial account of the balance of payments, the immediate effect is felt on the short-term financial flows part of the account as investors anticipate such moves and the consequent fall in sterling.

As far as monetary policy is concerned, the fall in sterling is in response to four things announced or signalled by Mark Carney at recent news conferences (see Monetary and fiscal policies – a U-turn or keeping the economy on track?).

First is the anticipated fall in Bank Rate at the next meeting of the Monetary Policy Committee on 13/14 July. Second is the possibility of further quantitative easing (QE). Third is an additional £250bn of liquidity that the Bank is prepared to provide through its normal open-market operations. Fourth is the easing of capital requirements on banks (reducing the countercyclical buffer from 0.5% to 0%), which would allow additional lending by banks of up to £150bn.

Lower interest rates, additional liquidity and further QE would all increase the supply of sterling on the foreign exchange markets. The anticipation of this, plus the anticipation of lower interest rates, would decrease the demand for sterling. The effect of these supply and demand changes is a fall in the exchange rate.

But is a fall in the exchange rate a ‘good thing’? As far as consumers are concerned, the answer is no. Imports will be more expensive, as will foreign holidays. People’s pounds will buy less of things priced in foreign currency and thus people will be poorer.

As far as exporters are concerned, however, the foreign currency they earn will exchange into more pounds than before. Their sterling revenues, therefore, are likely to increase. They might also choose to reduce the foreign currency price of exports, thereby increasing the quantity sold – the amount depending on the price elasticity of demand. The increase in exports and reduction in imports will help to reduce the current account deficit and also boost aggregate demand.

Before the referendum, economists overwhelmingly argued that the economic case for the UK remaining in the EU was much stronger than that for leaving. They warned of serious economic consequences, both short term and long term, of a Brexit vote. And yet, by a majority of 51.9% to 48.1% of the 72.1% of the electorate who voted, the UK voted to leave the EU.

Does this mean that economists failed to communicate to the electorate? Were the arguments presented poorly or in too academic a way?

Or did people simply not believe the economists’ forecasts, being cynical about the ability of economists to forecast? During the campaign, on several occasions I heard people repeating the joke that economists had successfully predicted five out of the last two recessions!

Did they not believe the data that immigrants from other EU countries to the UK contribute more in taxes they draw in benefits and that overall they make a net positive contribution to output per head? Or perhaps they believed the claims that immigrants imposed a net cost on the economy.

Or were there ‘non-economic’ issues that people found more persuasive, such as questions of sovereignty or national identity? Or was the strain on local resources, such as health services, schools and housing, blamed on immigration itself rather than on a lack of spending on additional resources – the funding for which could have come from the extra GDP generated by the immigration?

Or were there so many lies told by politicians and those with vested interests that people simply didn’t know whom to believe?

Economists will, no doubt, do a lot of soul searching over the coming months. One such economist is Paul Johnson, Director of the Institute for Fiscal Studies, whose article is linked below.

What have been, and will be, the monetary and fiscal responses to the Brexit vote in the referendum of 23 June 2016? This question has been addressed in speeches by Mark Carney, Governor of the Bank of England, and by George Osborne, Chancellor the Exchequer. Both recognise that the vote will cause a negative shock to the economy, which will require some stimulus to aggregate demand to avoid a recession, or at least minimise its depth.

Mark Carney stated that:

The Bank of England stands ready to provide more than £250bn of additional funds through its normal facilities. The Bank of England is also able to provide substantial liquidity in foreign currency, if required.

In the coming weeks, the Bank will assess economic conditions and will consider any additional policy responses.

This could mean that at its the next meeting, scheduled for 13/14 July, the Monetary Policy Committee will consider reducing Bank Rate from its current level of 0.5% and introducing further quantitative easing.

In a speech on 30 June, he went further:

I can assure you that in the coming months the Bank can be expected to take whatever action is needed to support growth subject to inflation being projected to return to the target over an appropriate horizon, and inflation expectations remaining well anchored.

Then in a speech on 5 July, introducing the latest Financial Stability Report, he said that the Bank of England’s Financial Policy Committee is lowering the required capital ratio of banks, thereby freeing up capital for lending to customers. The part being lowered is the ‘countercyclical capital buffer’ – the element that can be varied according to the state of the economy. Mark Carney said:

The FPC is today reducing the countercyclical capital buffer on banks’ UK exposures from 0.5% to 0% with immediate effect. This is a major change. It means that three quarters of UK banks, accounting for 90% of the stock of UK lending, will immediately have greater flexibility to supply credit to UK households and firms.

Specifically, the FPC’s action immediately reduces regulatory capital buffers by £5.7 billion and therefore raises banks’ capacity to lend to UK businesses and households by up to £150 billion. For comparison, last year with a fully functioning banking system and one of the fastest growing economies in the G7, total net lending in the UK was £60 billion.

Thus although there may be changes to interest rates and narrow money in response to economic reactions to the Brexit vote, the monetary policy framework remains unchanged. This is to achieve a target rate of CPI inflation of 2% at the 24-month time horizon.

But what of fiscal policy?

In its Charter for Budget Responsibility, updated in the Summer 2015 Budget, the government states its Fiscal Mandate:

3.2 In normal times, once a headline surplus has been achieved, the Treasury’s mandate for fiscal policy is:
   a target for a surplus on public-sector net borrowing in each subsequent year.

3.3 For the period outside normal times from 2015-16, the Treasury’s mandate for fiscal policy is:
   a target for a surplus on public-sector net borrowing by the end of 2019-20.

3.4 For this period until 2019-20, the Treasury’s mandate for fiscal policy is supplemented by:
   a target for public-sector net debt as a percentage of GDP to be falling in each year.

The target of a PSNB surplus by 2019-20 has been the cornerstone of recent fiscal policy. In order to stick to it, the Chancellor warned before the referendum that a slowdown in the economy as a result of a Brexit vote would force him to introduce an emergency Budget, which would involve cuts in government expenditure and increases in taxes.

However, since the vote he is now saying that the slowdown would force him to extend the time for reaching a surplus beyond 2019-20 to avoid dampening the economy further. But does this mean he is abandoning his fiscal target and resorting to discretionary expansionary fiscal policy?

George Osborne’s answer to this question is no. He argues that extending the deadline for a surplus is consistent with paragraph 3.5 of the Charter, which reads:

3.5 These targets apply unless and until the Office for Budget Responsibility (OBR) assess, as part of their economic and fiscal forecast, that there is a significant negative shock to the UK. A significant negative shock is defined as real GDP growth of less than 1% on a rolling 4 quarter-on-4 quarter basis. If the OBR assess that a significant negative shock:

occurred in the most recent 4 quarter period;
is occurring at the time the assessment is being made; or
will occur during the forecast period

then:

  if the normal times surplus rule in 3.2 is in force, the target for a surplus each year is suspended (regardless of future data revisions). The Treasury must set out a plan to return to surplus. This plan must include appropriate fiscal targets, which will be assessed by the OBR. The plan, including fiscal targets, must be presented by the Chancellor of the Exchequer to Parliament at or before the first financial report after the shock. The new fiscal targets must be approved by a vote in the House of Commons.
  if the shock occurs outside normal times, the Treasury will review the appropriateness of its fiscal targets for the period until the public finances return to surplus. Any changes to the targets must be approved by a vote in the House of Commons.
  once the budget is in surplus, the target set out in 3.2 above applies.

In other words, if the OBR forecasts that the Brexit vote will result in GDP growing by less than 1%, the Chancellor can delay reaching the surplus and thus not have to introduce tougher austerity measures. This, in effect, is what he is now saying and maintaining that, because of paragraph 3.5, it does not break the Fiscal Mandate. The nature of the next Budget, probably in the autumn, will depend on OBR forecasts.

A few days later, George Osborne announced that he plans to cut corporation tax from the current 20% to less than 15% – below the rate of 17% previously scheduled for 2019-20. His aim is not just to stimulate the economy, but to attract inward investment, as the rate would below that of any major economy and close the rate of 12.5% in Ireland. His hope would also be to halt the outflow of investment as companies seek to relocate in the EU.

Many of the arguments used by both sides in the referendum debate centre on whether there will be a net economic gain from either remaining in or leaving the EU. This involves forecasting.

Forecasting the economic impact of the decision, however, is difficult, especially in the case of a leave vote, which would involve substantial change and uncertainty.

First, the effects of either remaining or leaving may be very different in the long run from the short run, and long-run forecasts are highly unreliable, as the economy is likely to be affected by so many unpredictable events – few people, for example, predicted the financial crisis of 2007–8.

Second, the effects of leaving depend on the nature of any future trading relationships with the EU. Various possibilities have been suggested, including ‘the Norwegian model’, where Britain leaves the EU, but joins the European Economic Area, giving access to the single market, but removing regulation in some key areas, such as fisheries and home affairs. Another possibility is ‘the Swiss model’, where the UK would negotiate trade deals on an individual basis. Another would be ‘the Turkish model’ where the UK forms a customs union with the EU. At the extreme, the UK could make a complete break from the EU and simply use its membership of the WTO to make trade agreements.

Nevertheless, despite the uncertainty, economists have ventured to predict the effects of remaining or leaving. These are not precise predictions for the reasons given above. Rather they are based on likely assumptions.

In a poll of 100 economists for the Financial Times, ‘almost three-quarters thought leaving the EU would damage the country’s medium-term outlook, nine times more than the 8 per cent who thought the country would benefit from leaving’. Most fear damage to financial markets in the UK and to inward foreign direct investment.

Despite the barrage of pessimistic forecasts by economists about a British exit, there is a group of eight economists in favour of Brexit. They claim that leaving the EU would lead to a stronger economy, with higher GDP, a faster growth in real wages, lower unemployment and a smaller gap between imports and exports. The main argument they use to support their claims is that the UK would be more able to pursue trade creation freed from various EU rules and regulations.

Then, less than four weeks before the vote, a poll of economists who are members of the Royal Economic Society and the Society of Business Economists came out strongly in favour of continued membership of the EU. Of the 639 respondents, 72 per cent thought that the most likely impact of Brexit on UK real GDP would be negative over the next 10 to 20 years; and 88 per cent thought the impact on GDP would be negative in the next five years (see chart: click to enlarge).

Of those stating that a negative impact on GDP in the next 5 years would be most likely, a majority cited loss of access to the single market (67%) and increased uncertainty leading to reduced investment (66%).

The views of the majority of economists accord with those of various organisations. Domestic ones, such as the Bank of England, the Treasury (see the blog Brexit costs), the Institute for Fiscal Studies and the National Institute for Economic and Social Research (NIESR) all warn that Brexit would be likely to result in lower growth – possibly a recession – increased unemployment, a fall in the exchange rate and higher prices and that greater economic uncertainty would damage investment.

International organisations, such as the OECD, the IMF and the WTO, also argue that leaving the EU would create great uncertainty over future trade relations and access to the Single Market and would reduce inward foreign direct investment and the flow of skills.

But the forecasts of all these organisations depend on their assumptions about trade relations and that, in the event of the UK leaving the EU, would depend on the outcome of trade negotiations. The Leave campaign argues that other countries would want to trade with the UK and that therefore leaving would not damage trade. The Remain campaign argues that the EU would not wish to be generous to the UK for fear of encouraging other countries to leave the EU and that, anyway, the process of decoupling from the EU and negotiating new trade deals would take many years and, in the meantime, the uncertainty would be damaging to investment and growth.

The articles linked below looks at the economic arguments about Brexit and reflect the range of views of economists. Several are from ‘The Conversation’ as these are by academic economists. Although some economists are in favour of Brexit, the vast majority support the Remain side in the debate.
