Nouriel Roubini: The last three global recessions (prior to 2008) were each caused by a geopolitical shock in the Middle East that led to a sharp spike in oil prices. The 1973 Yom Kippur War between Israel and the Arab states led to global stagflation (recession and inflation) in 1974-1975. The Iranian revolution in 1979 led to global stagflation in 1980-1982. And Iraq’s invasion of Kuwait in the summer of 1990 led to the global recession of 1990-1991.
Even the recent global recession, though triggered by a financial crisis, was exacerbated by spiking oil prices in 2008. With the barrel price reaching $145 in July of that year, oil-importing advanced economies and emerging markets alike faced a recessionary tipping point.
……..Oil is already well above $100/barrel, despite weak economic growth in advanced countries and many emerging markets. The fear premium might push prices significantly higher, even if no military conflict ultimately takes place, and could trigger a global recession if one does.
