U.S. crude oil price fell on Monday as the dollar strengthened and European weak data caused recession worry.
Industrial production in the euro zone fell 2.0 percent in September, the most since early 2009, according to data from the European Union's statistics office. This added to recession fears in the 17-country bloc, intending to hurt oil demand.
And the debt crisis, which had driven crude prices ups and downs for months, continued to weigh on markets. Italy's five-year government bond yield surged to euro-era high on Monday even though Mario Monti, the former European Commissioner became the new leader for the debt-burdened country. This indicated lack of confidence in Italy's creditability.
In Greece, new Prime Minister Lucas Papademos will face confidence vote in his cabinet on Wednesday. Uncertainties about Athens' future continued.
