欧州の独立系シンクタンク、ブリューゲル社:フランスのEU(欧州連合)離脱は困難かつデメリットが大きいと主張


Default: Change to:


‘Frexit’ supporters promise that the benefits of leaving the euro would be substantial for the French economy,and that the exit process would be a piece of cake. This blog post shows that these claims are greatly exaggerated if not outright lies.


Myth 1: Frexit would unambiguously boost French competitiveness

Advocates of leaving the Euro claim that Frexit would provide a competitiveness boost to French exports and essentially solve two alleged problems: the persistent trade deficit and the decline in market share for French goods, especially compared to Germany. [...]

First of all, these two problems are largely exaggerated. The decline in export market share since 2000 is not specific to France and is actually the norm across industrialised countries. It is the result of China and other emerging countries joining the global economy. Germany’s stable share is actually an outlier in comparison to other advanced countries. As for the French trade deficit, it has in fact slowly decreased over the last 5 years and its current level (-1.3%) is not a concern.

In addition, the Euro has weakened over the last two years due to the accommodative monetary policy of the ECB. And this has already provided a significant boost in terms of price competiveness. Since mid-2014, the Euro has depreciated by 25% against the US dollar and it cannot be considered overvalued for the euro area as a whole.

In fact, the main issue comes from imbalances within the Eurozone. According to a recent estimation, France is, in real terms, overvalued by 7% with respect to the Eurozone average and by 20% with respect to Germany. A new French currency (let’s called it the Franc for simplicity) would thus probably depreciate against the Euro after its introduction. [...]

So, overall, it is true that a flexible exchange rate is a helpful adjustment mechanism to absorb temporary shocks and to reduce external imbalances, if combined with a credible monetary policy framework. However, France does not really have an overvaluation problem relative to the rest of the world and within the euro area the country is not very far from the average. Supposed gains in terms of price competitiveness would thus be much less significant than what Frexit supporters suggest.

 

Myth 2: Frexit would lead to a more appropriate monetary policy

Another major benefit promised by Frexit advocates is an independent monetary policy tailored to the domestic economy and not to the Eurozone average. This argument is valid in theory, but in practice it is once again not relevant for France. France is generally well represented by the Eurozone average because its economy behaves like the average of the euro area. For instance, the interest rate prescriptions provided by simple Taylor rules (see graph below) for France and the euro area are very similar. This suggest that monetary policy decisions made by an independent Banque de France following a mandate similar to the ECB’s would not be so different than the ones taken by the ECB governing council.

An exit from the monetary union could actually make French monetary policy more difficult, especially in the short term, as it might lead to an increase of inflation to undesired levels. Not only would the Franc depreciate, but the experiences of countries abruptly changing exchange rate regimes suggest that some overshooting would take place beyond what fundamentals require.

Depreciations make imports more expensive, and past episodes of rapid currency depreciation (see table below) suggest an immediate surge in inflation. Given the importance of imports in some key sectors in France (energy in particular), a strong depreciation of the Franc would have a negative effect on the economy in the short term and would (at least) lead to a temporary spike in inflation.

To ensure that the spike is only temporary, a credible monetary framework would need to be established quickly. This is, however, incompatible with other policies advocated by the partisans of Frexit, who also want to deprive the Banque de France of its independence and authorise direct financing of the government by the central bank. This appears especially incoherent with the promise by Frexit advocates to keep inflation low after leaving the Euro.

Frexit advocates want to get rid of the Euro to boost French exports, but paradoxically they are also sceptical towards a fully flexible exchange rate regime because they fear excessive volatility in the foreign exchange market. In fact, general public support for flexible rates has always been relatively weak in France. That’s why some Frexit partisans are pleading for the return to the ECU and to the European system of fixed exchange rates that was in place before Maastricht. It is strange to want to leave a common currency only to bind yourself to another currency in a fixed exchange rate system.

Even putting aside this paradox, pegging oneself to a foreign currency requires policy credibility to achieve exchange rate stability. Monetary sovereignty under such a system is in practice illusory because the Banque de France would have to adjust its policies to defend its parity and thus adapt its interest rates in reaction to its neighbour’s cyclical situation (be it the Eurozone or Germany). In this case, the current shared sovereignty in the Governing Council of the ECB appears preferable in terms of macroeconomic policy performance, as well as sovereignty.

 

Myth 3: Frexit would relax constraints on fiscal policy

Frexit partisans suggest that leaving the Euro could free the country from the constraints of European fiscal rules and allow the French government to pursue a more countercyclical fiscal policy. But countercyclical fiscal policy doesn’t seem to be a French speciality anyway, and leaving the Euro could damage France’s credibility, making it difficult to borrow the money needed for counter-cyclical spending.

[...] Conversion of public debt from Euros to Francs might be possible from a legal perspective but such a drastic change in the conditions of debt instruments could be technically considered as a default by rating agencies. This would make it more costly for the French government to borrow from financial markets, and could even result in France losing access to international markets for a few years.

In any case, it would be logical for international investors to require higher interest rates in new bond issuances to compensate for the depreciation of the currency and to hedge against inflation risk.  The French government would also be under much more market scrutiny. In addition, in the long run, franc-denominated debts would lose the benefits of being issued in a reserve currency, a status reserved to countries with a long history of credible and stable monetary policy.

For all these reasons, borrowing from international markets to support the economy when needed could become much more difficult and expensive. And trying to circumvent that by using the central bank to finance budget deficits will not be a good idea at a time where it needs to establish its credibility to anchor inflation at a low level or to defend a stable exchange rate.

 

Myth 4: Frexit would be painless for French companies

[...] The biggest risk would therefore come from other debt instruments such as cross-border loans from foreign banks and bonds issued under foreign law by French banks and big non-financial corporations. In aggregate, the situation could ex ante appear to be manageable, but many companies would be affected by currency mismatches. In practice, at the micro-level, the transition would be chaotic and lead to thousands of endless legal disputes that would hurt economic activity. These mismatches would lead to many instances of debt restructuring, possible bankruptcies or bailouts of systemic actors, and the subsequent negative impact on creditors, shareholders and taxpayers. Frexit would end up looking like a lottery for all companies in France: having more assets or more liabilities converted into Francs would determine whether they are bankrupt or richer after Frexit.

 

Myth 5: Frexit would be smooth and orderly

[...] In fact, the very idea of quietly organising a referendum in France followed by a calm negotiation with European partners is illusory. The main issue is that a ‘preventative’ bank run and capital flight would take place as soon as people consider Frexit a credible possibility and expect their deposits to be converted into a weakening currency. Depositors participating in a bank run would be perfectly rational in that case. 

In France, a euro exit is still considered as a tail risk by markets and depositors for the moment, but sovereign bond markets have already reacted to changing probabilities of Frexit. If Frexit was becoming more probable, deposit withdrawals and the sovereign risk premium could increase quickly.

Another risk is that Frexit could happen by accident, before it could be properly organised or even before a referendum. Imagine, for instance, a scenario in which the Front National wins the elections and the French government’s rating were downgraded by all major ratings agencies below BBB- (following Fitch and Standard & Poor’s rating system). This would make it difficult for French banks – who could also be facing a bank run at that time – to access the main refinancing operations of the ECB, as they would not be able to use French government bonds as collateral in the Eurosystem monetary operations. In turn, they could be forced to use the – more expansive but also more flexible in terms of collateral – Emergency Liquidity Assistance (ELA) at the Banque de France under limits set by the ECB’s Governing Council.

The situation would then be pretty similar to one in Greece in February 2015. And as in 2015, the ECB would be caught in extremely political discussions about whether it should continue providing liquidity to the French banking sector to face the run or not. The decision would be even more complex for the ECB this time because the ECB would face a government openly favourable to an exit from the monetary union. And if its decision were to stop providing liquidity, the Banque de France and the French government would have no other choice but to decide whether to impose very strict capital controls or to launch a new currency to provide the needed liquidity to the banking sector. The risk of Frexit could thus become a self-fulfilling prophecy.

The probability of such a scenario is today extremely low and the sequence of events to arrive at that point unlikely. But this thought experiment shows how quickly such a situation could spin out of control and lead to a disorderly exit from the monetary union, which could have devastating consequences for the French economy.

Overall, it is important to realize that the French financial system is at the core of the euro area financial system and is tightly interwoven with the global financial system. Frexit would lead to a freezing of financial flows and bring the global financial system to a cardiac arrest. The failure of Lehman brothers could look like a small shock in comparison, and even that had major real economic implications. [...]
