How imbalances led to credit crunch and inflation

Inflation is always and everywhere a monetary phenomenon. Milton Friedman
WHAT explains the combination of a "credit crunch" in the US with soaring commodity prices and rising inflation across the globe? Are these unrelated events or part of a bigger picture? The answer is the latter. So far this is not a return to the 1970s. But action is needed to keep this true.
Inflation is a sustained rise in the price level: the result of too much money (or purchasing power) chasing too few goods and services. A one-off jump in commodity prices is not inflation. Nor need such a jump cause inflation. But a continuous rise in the relative price of commodities is a symptom of an inflationary process.
Whenever excess demand hits, the goods whose prices rise first are ones with flexible prices, of which commodities are the prime example. Commodity prices then are a pressure gauge. If we look at what has been happening in recent years, the gauge is showing red. The Goldman Sachs index of commodity prices has doubled since early 2007. Nominal prices of oil have increased by 150 per cent over the same period. The upward movement in commodity prices has persisted for 6
