Martin Wolf, in the Financial Times, will scare you today. He says that by the numbers, we are in a “contained depression” — but that forces are building that threaten to breach the containment walls, and lead to total meltdown. Excerpts:

It is often forgotten that the failure of Austria’s Creditanstalt in 1931 led to a wave of bank failures across the continent. That turned out to be the beginning of the end of the gold standard and caused a second downward leg of the Great Depression itself. The fear must now be that a wave of banking and sovereign failures might cause a similar meltdown inside the eurozone, the closest thing the world now has to the old gold standard. The failure of the eurozone would, in turn, generate further massive disruption in the European and even global financial systems, possibly even knocking over the walls now containing the depression.

How realistic is this fear? Quite realistic.

Before now, I had never really understood how the 1930s could happen. Now I do. All one needs are fragile economies, a rigid monetary regime, intense debate over what must be done, widespread belief that suffering is good, myopic politicians, an inability to co-operate and failure to stay ahead of events. Perhaps the panic will vanish. But investors who are buying bonds at current rates are indicating a deep aversion to the downside risks. Policy makers must eliminate this panic, not stoke it.
