Uiteenvallen eurozone onvermijdelijk

The muddle-through approach to the eurozone crisis has failed to resolve the fundamental problems of economic and competitiveness divergence within the union. If this continues the euro will move towards disorderly debt workouts, and eventually a break-up of the monetary union itself, as some of the weaker members crash out.

The reality turned out to be different. Paradoxically the halo effect of early interest rate convergence allowed a greater divergence in fiscal policies. A reckless lack of discipline in countries such as Greece and Portugal was matched only by the build-up of asset bubbles in others like Spain and Ireland. Structural reforms were delayed, while wage growth relative to productivity growth diverged. The result was a loss of competitiveness on the periphery.

Eurozone debt reduction or “reprofiling” will help to resolve the issue of excessive debt in some insolvent economies. But it will do nothing to restore economic convergence, which requires the restoration of competitiveness convergence. Without this the periphery will simply stagnate.

there is really only one other way to restore competitiveness and growth on the periphery: leave the euro, go back to national currencies and achieve a massive nominal and real depreciation. After all, in all those emerging market financial crises that restored growth a move to flexible exchange rates was necessary and unavoidable on top of official liquidity, austerity and reform and, in some cases, debt restructuring and reduction.

The eurozone was glued together by the convergence of low real interest rates sustaining growth, the hope that reforms could maintain convergence; and the prospect of eventual fiscal and political union. But now convergence is gone, reform is stalled, while fiscal and political union is a distant dream.

Debt restructuring will happen. The question is when (sooner or later) and how (orderly or disorderly). But even debt reduction will not be sufficient to restore competitiveness and growth. Yet if this cannot be achieved, the option of exiting the monetary union will become dominant: the benefits of staying in will be lower than the benefits of exiting, however bumpy or disorderly that exit may end up being.
