Oil prices slumped this morning after the US mounted its first attack of the war in Iraq. US crude prices have tumbled by USD1.88 a barrel to a three month low of USD28, as traders bet on a swift war that does not disrupt oil supplies from neighbouring countries. Markets have also been reassured by a renewed pledge from the OPEC oil cartel to fill any supply gap caused by a lack of supplies from Iraq. OPEC said it was ready to add 5-6m barrels a day to the market if Iraqi oil was lost. //www.fxcentre.com
