What we’re seeing in Europe — in rising Italian borrowing costs and the felling of two prime ministers — is the growing impatience of the markets for a resolution to the euro zone crisis. To put a finer point on it, the hive mind of the markets has decided it is not going to give Europe enough time to get its act together. The big institutions that drive the world’s economies are sitting on huge amounts of cash — enough to solve many of these problems overnight. But they have lost confidence in the ability of the European political system to deliver solutions that will work.

In a G-Zero world, where there is no strong global leader to direct the course of events, no one is interested in taking a flier on helping the Europeans get out of their mess. As the abortive G-20 conference showed last week, there is no backstop for any country or institution that makes an error in today’s environment, whether it’s tiny MF Global or the Chinese sovereign debt fund. In the postwar era, the Marshall Plan was the very definition of global security — it was a huge commitment by the U.S. to rebuild Europe into the economic force (and not incidentally, trading partner) that the world needed. Today, there is no Marshall plan for Europe, from within or without.

That’s the high-level view of the Europe situation. The question everyone wants answered is this: what happens next? Start with Greece: the best possible outcome for that country has happened with Papandreou’s resignation and the selection of economist Lucas Papademos as Prime Minister of an emergency government. Papademos is committed to remaining in the euro and accepting the terms of the Greek bailout package. Despite the roller coaster ride Papandreou took his country and the euro zone on, Greece has now moved closer to the Spanish and Portuguese models for avoiding the debt crisis drama. In Greece, a resolution is starting to be reached. It’s not the beginning of the end, but maybe this is the end of the beginning.

The same can’t be said for Italy as the situation changes by the day. The decisive Senate approval of a package of austerity measures (by a margin of 156 to 12) was one small step for Italy in the eyes of the markets— and a big step toward Silvio Berlusconi resigning his mandate.  It’s a wonder that Berlusconi held on to power for so long; he burned up his political capital years ago with scandals of all stripes. His stepping down is good news for Italy in the long run, but the handover of power to likely frontrunner Mario Monti is a delicate process that will have to be handled with tremendous care.  Unfortunately for Italy, political drama has insured it will face a higher and longer level of scrutiny.

Markets will continue to demand extensive and enforceable changes in spending levels throughout the peripheral states. When Italy and Greece look more like Spain and Portugal, the bond markets will treat them more like Spain and Portugal.  But that alone won’t solve the problem: investors are going to demand to know what happens next time any euro zone periphery country is on the brink of collapse. Euro zone institutions and politics have to be reshaped to prevent this type of crisis from ever happening again. Until this risk is mitigated, lending costs will stay high for a long time to come.
