Acton’s director of research Samuel Gregg is up at Public Discourse, with a piece titled “Monetary Possibilities for a Post-Euro Europe.” With his usual mix of sophisticated economic analysis and reference to deep principles, Gregg considers European countries’ options should the eurozone fail. If that happens, he says, “European governments will have a once-in-a-lifetime opportunity to rethink the type of monetary order they wish to embrace.”

One such scenario is a three-way monetary division within the EU that reflects the differing mitments and economic priorities of different nations. Germany and the more fiscally responsible eurozone members such as Austria, Finland, and the Netherlands could, for instance, decide to reconcile themselves to being the only ones with the necessary fiscal and monetary discipline to maintain mon currency.

Alongside this bloc would be two other groups. One would consist of those EU countries such as Britain, Sweden, and Denmark that have maintained their own monetary systems because of reservations about the euro’s implications for national sovereignty. Another group would include EU nations such as Greece, Portugal, and Italy that are simply unable or unwilling to embrace the disciplined monetary and fiscal policies required by mon currency; these nations would consequently find themselves outside the eurozone and reverting to their national currencies.

A more radical monetary opportunity for a post-euro EU would be petition.This was once proposed by Britain’s Margaret Thatcher as an alternative to the mon currency. Contemporary proposals for petition, such as thatadvancedby Philip Booth and Alberto Mingardi, involve the monetary authorities of different countries authorizing the use of currencies alongside the euro in domestic settings other than their own. Consumer choice rather than state sovereignty would thus ultimately determine which currencies were used.

Yet another option would be the embrace of what might be called a European gold standard. In the 1950s and 1960s, the German economist Wilhelm Röpke argued that European monetary integration could occur via a nucleus of countries agreeing to adhere to a gold standard, much as had happened somewhat spontaneously in the nineteenth century through a process of unilateral decision-making by individual countries. Once this had occurred, adherents of such a gold standard would have to insist upon all members maintaining monetary discipline as well as freedom and stability in foreign exchange markets.

The stability of the European currency would be assured not by EU bureaucrats, but by the gold standard itself, and by allowance for the expulsion of countries that abuse their big-boy privileges.

Britain just rejected an EU treaty because the Conservative Party decided Brussels was trying to capitalize on the Mediterranean crisis by grabbing more power. The three proposed currency models, Gregg argues, would maintain countries’ freedom by yanking monetary power from central bureaucrats who exercise political power. He reflects further on position and history of the eurozone, on the countries’ political and economic freedom, and on what Röpke would have to say in the rest of the piece.
