Monetary policy’s various guises from near-zero short-term interest rates, to massive liquidity injections, to quantitative easing and its relatives have so far had no traction in this crisis. While the global economy is no longer shrinking at quite the speeds seen at the beginning of the year, it is still trapped in a bad recession.

The main reason for its longevity is the state of the banking sector. The European Central Bank has recently pumped €442bn ($620bn, £380bn) in one-year liquidity into the system, but the money is not reaching the real economy. Japanese-style stagnation is no longer possible – it is already here. The only question is how long it will last. Even in an optimistic scenario, global economic growth will be weighed down by a combination of credit squeeze, rising unemployment, rising bankruptcies, rising default rates, and balance sheet adjustment in the household and financial sectors.
