Central banks may soon resort to their most powerful weapons against deflation: the printing press and the “helicopter drop” of money. It is a time for which Ben Bernanke, chairman of the Federal Reserve, has long prepared. Will this weaponry work? Unquestionably, yes: used ruthlessly, it will eliminate deflation. But returning to normality thereafter will prove far more elusive.
Mr Bernanke delivered a celebrated speech on the topic in November 2002, when still a governor. He spoke quite soon after the US stock market bubble burst in 2000. Policymakers then feared the US might soon follow Japan into deflation – sustained declines in the general price level.
Yet Mr Bernanke then insisted “that the chance of significant deflation in the US in the foreseeable future is extremely small”. He pointed to “the strength of our financial system: despite the adverse shocks of the past year, our banking system remains healthy and well-regulated, and firm and household balance sheets are for the most part in good shape”. The words “pride” and “fall” come to mind. Six years and a housing-cum-credit bubble later, chairman Bernanke must be sadder and wiser.
