At last month's Seoul summit of the G20 — or the G19 +1, as one senior
Asian central bank official recently dubbed it — the US was isolated from the other world economic powers by the Federal Reserve's decision to print hundreds of billions of dollars to boost the struggling US economy.
Among the explanations that have been put forward are the increased credibility of
central banks in controlling inflation (inflation rates remain below 3 per cent across the developed world), the low level of
official interest rates in the major economies reflecting low inflation and the continuing weakness in some economies, a glut of savings on world markets particularly sourced from the
Asian region, and changes to pension fund rules in some countries which are seen as biasing investments away from equities towards bonds.
