The economic consequences of the Arab revolt

Indeed, should stagflation emerge, there is a serious risk of a double-dip recession for a global economy that has barely emerged from its worst crisis in decades.

Severe unrest in the Middle East has historically been a source of oil-price spikes, which in turn have triggered three of the last five global recessions. The Yom Kippur War in 1973 caused a sharp increase in oil prices, leading to the global stagflation of 1974-1975. The Iranian revolution in 1979 led to a similar stagflationary increase in oil prices, which culminated in the recession of 1980-1981. And Iraq's invasion of Kuwait in August 1990 led to a spike in oil prices at a time when a US banking crisis was already tipping America into recession.
