Greece Must Go

The nation is likely to leave the eurozone sooner or later. Sooner is better.

The Greek euro tragedy is reaching its final act: It is clear that either this year or next, Greece is highly likely to default on its debt and exit the eurozone. Postponing the exit until after the June election with a new government committed to a variant of the same failed policies (recessionary austerity and structural reforms) will not restore growth and competitiveness. Greece is stuck in a vicious cycle of insolvency, lost competitiveness, external deficits, and ever-deepening depression. The only way to stop it is to begin an orderly default and exit, coordinated and financed by the European Central Bank, the European Union, and the International Monetary Fund (the “troika”), that minimizes collateral damage to Greece and the rest of the eurozone.

Greece’s recent financing package, overseen by the troika, gave the country much less debt relief than it needed. But, even with significantly more public-debt relief, Greece could not return to growth without rapidly restoring competitiveness. And, without a return to growth, its debt burden will remain unsustainable. But all of the options that might restore competitiveness require real currency depreciation.

The first option, a sharp weakening of the euro, is unlikely, as Germany is strong and the ECB is not aggressively easing monetary policy. A rapid reduction in unit labor costs, through structural reforms that increased productivity growth in excess of wages, is just as unlikely. It took Germany 10 years to restore its competitiveness this way; Greece cannot remain in a depression for a decade. Likewise, a rapid deflation in prices and wages, known as an “internal devaluation,” would lead to five years of ever-deepening depression.


If none of those three options is feasible, the only path left is to leave the eurozone. A return to a national currency and a sharp depreciation would quickly restore competitiveness and growth.

Of course, the process would be traumatic, and not just for Greece. The most significant problem would be capital losses for core eurozone financial institutions. Overnight, the foreign euro liabilities of Greece’s government, banks, and companies would surge. Yet these problems can be overcome. Argentina did so in 2001, when it “peso-fied” its dollar debts. The United States did something similar in 1933, when it depreciated the dollar by 69 percent and abandoned the gold standard. A similar “drachma-tization” of euro debts would be necessary and unavoidable.

Losses that eurozone banks would suffer would be manageable if the banks were properly and aggressively recapitalized. Avoiding a post-exit implosion of the Greek banking system, however, might require temporary measures, such as bank holidays and capital controls, to prevent a disorderly run on deposits. The European Financial Stability Facility/European Stability Mechanism should carry out the necessary recapitalization of the Greek banks via direct capital injections. European taxpayers would effectively take over the Greek banking system, but this would be partial compensation for the losses imposed on creditors by drachma-tization.

Greece would also have to restructure and reduce its public debt again. The troika’s claims on Greece need not be reduced in face value, but their maturity would have to be lengthened by another decade, and the interest on it reduced. Further haircuts on private claims would also be needed, starting with a moratorium on interest payments.

Some argue that Greece’s real GDP would be much lower in an exit scenario than it would be during the hard slog of deflation. But that is logically flawed: Eeven with deflation, real purchasing power would fall, and the real value of debts would rise (debt deflation), as the real depreciation occurs. More importantly, the exit path would restore growth right away, via nominal and real depreciation, avoiding a decade-long depression. And trade losses imposed on the eurozone by the drachma depreciation would be modest, given that Greece accounts for only 2 percent of eurozone GDP.

Reintroducing the drachma risks exchange-rate depreciation in excess of what is necessary to restore competitiveness, which would be inflationary and impose greater losses on drachmatized external debts. To minimize that risk, the troika reserves currently devoted to the Greek bailout should be used to limit exchange-rate overshooting; capital controls would help, too.

Those who claim that contagion from a Greek exit would drag others into the crisis are also in denial. Other peripheral countries already have Greek-style problems of debt sustainability and eroded competitiveness. Portugal, for example, may eventually have to restructure its debt and exit the euro. Illiquid but potentially solvent economies, such as Italy and Spain, will need support from Europe regardless of whether Greece exits; indeed, without such liquidity support, a self-fulfilling run on Italian and Spanish public debt is likely.
