Gerd Haeusler, director of the International Department of the IMF, was speaking in London at the launch of the IMF's latest report on global financial stability. He said that judging from the spike in oil prices before the Gulf War in 1991 'the most realistic scenario' for how war with Iraq would play out would include another 'oil price spike'. Given other uncertainties 'this might put the financial system under additional stress', he said.
