Gavyn Davies: How big is the 2011 oil price shock?

Gavyn Davies: How big is the 2011 oil price shock? Each of the last five major downturns in global economic activity has been immediately preceded by a major spike in oil prices. Sometimes (e.g. in the 1970s and in 1990), the surge in oil prices has been due to supply restrictions, triggered by Opec or by war in the Middle East. Other times (e.g. in 2008), it has been due to rapid growth in the demand for oil.

But in both cases the contractionary effects of higher energy prices have eventually proven too much for the world economy to shrug off. With the global average price of oil having moved above $100 per barrel in recent days – about 33 per cent higher than the price last summer – it is natural to fear that this latest oil shock may be enough to kill the global economic recovery. But oil prices would have to rise much further, and persist for much longer, for these fears to be justified.
