Wolfgang Münchau in the Financial Times writes:
Our present situation can give rise to two scenarios – or some combination of the two. The first is that central banks start exiting at some point in 2010, triggering another fall in the prices of risky assets. In the UK, for example, any return to a normal monetary policy will almost inevitably imply another fall in the housing market, which is currently propped up by ultra-cheap mortgages."For all we know," as long as the solution is forbidden.
Alternatively, central banks might prioritise financial stability over price stability and keep the monetary floodgates open for as long as possible. This, I believe, would cause the mother of all financial market crises – a bond market crash – to be followed by depression and deflation.
In other words, there is danger no matter how the central banks react. Successful monetary policy could be like walking along a perilous ridge, on either side of which lies a precipice of instability.
For all we know, there may not be a safe way down.
