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.

Martin Wolf:

It is often forgotten, not least in Germany, that the rise of Adolf Hitler to power was preceded not by the great inflation, which occurred a decade before, but by the great depression and the austerity of Heinrich Brüning, in response. Thus, votes for the Nazi party jumped from a relatively insignificant 810,000 in 1928, to 6.4m in 1930, and 13.7m in July 1932. Deep economic collapses are dangerous.
