AS the European economic crisis continues to intensify, policy makers are faced with the need to take ever more extreme measures to prevent a financial cataclysm. Tomorrow, European Union leaders will meet in Brussels to discuss the latest proposals: centralizing banking regulation and putting limits on national spending and borrowing.

A better, bolder and, until now, almost inconceivable solution is for Germany to reintroduce the mark, which would cause the euro to immediately decline in value. Such a devaluation would give troubled economies, especially those of Greece, Italy and Spain, the financial flexibility they need to stabilize themselves.

Although repeated currency devaluations are not the path to prosperity, a weaker euro would give a boost in competitiveness to all members of the monetary union, including France and the Netherlands, which is why they might very well choose to remain in it even if Germany were to gradually leave. A resurgence of manufacturing would also allow the vast unemployment rolls of Spain, Portugal, Greece and other countries to begin to decline. The tremendous loss of human capital and human dignity we are witnessing would ease.

Reintroducing the mark would not solve the debt burdens of southern European countries, but it would give them needed breathing room to restructure their economies, reform labor markets, collect more taxes and reassure investors. The ability of the southern European countries to service their sovereign debt would immediately improve, helping to end the slow-burning debt and banking crises that have engulfed the Continent since 2008.
