Those who say this is nothing like the Great Depression are complacent. Household debt is higher today, and UK banks are in worse shape. (No bank of size failed in the British Empire during the slump). Britain's economy contracted by 5.6pc from peak to trough in the early 1930s (Eichengreen). Some put the figure at nearer 8pc. We may surpass that this time.
America suffered worse. Real GDP fell 28pc. But the worst occurred in the second leg, after the heinous policy blunders of late 1931. Reading contemporary accounts, it is clear that hardly anybody – not even Keynes or Fisher – realised that the world was slipping into a depression during the first 18 months.
Nobel laureate Paul Krugman says the Fed has been as far behind the curve today as it was then, given the faster pace of collapse. It is bizarre that Ben Bernanke has not started to buy US Treasuries a full three months after he floated the idea, despite a yield rise of 80 basis points.
