Hit by the shocks of hurricane Sandy and recession in much of Europe, the International Energy Agency has reduced its world oil demand forecasts for 2012 and 2013, it said on Tuesday. In its monthly report on the world oil market, the Paris-based IEA now believes global demand will increase by 670,000 barrels a day in 2012 to 89.6 million bpd. This is 60,000 bpd less than assumed a month ago. For 2013, the IEA slashed its demand forecast by 100,000 bpd to a rise of 830,000 bpd to reach 90.4 million bpd. The downward revisions are due mainly to sluggish economies in developed OECD countries and the knock-on effects of Hurricane Sandy which wrought havoc on the US eastern seabord three weeks ago. Sandy is expected to have slashed US demand by 230,000 barrels per day in October, as people curtailed travel and product deliveries were impeded. For 2012, US demand will dip by 310,000 bpd to 18.7 million bpd, the same 12-month total forecast for 2013, the IEA said. The other drag on demand was Europe, where the effects of the eurozone debt crisis have pushed much of the region into recession. Overall, European demand in the third quarter is 150,00 bpd lower than the previous estimate, the IEA said, \"as the already bleak outlook was with hindsight too optimistic.\" In Europe, the IEA envisages a 500,000 bpd contraction in demand this year to 13.8 million bpd followed by another contraction of 200,000 bpd in 2013 to 13.6 million bpd. Demand in powerhouse China, the world\'s biggest energy consumer, was on the otherhand revised slightly upwards for 2012 to 9.5 million bpd up by 260,000 bpd from the precious forecast. Chinese demand in 2013 will be 9.8 million bpd, a moderate increase.
