Crude oil prices fall

Crude oil prices fell on Tuesday as fears about the global economy resurfaced following reports that European banks may have more risky government debt on their books than previously thought.

Benchmark crude for October delivery fell 51 US cents to settle at $US74.09 a barrel on the New York Mercantile Exchange.

The Wall Street Journal reported that EU stress tests of 91 banks in July understated some lenders' holdings of potentially risky debt. The Financial Times said Germany's top 10 banks will have to raise as much as $US135 billion to meet new capital requirements.

In addition, abundant supplies of oil were expected to pull prices down over the next two months, with fewer US drivers on the road and the winter heating season still to come.

The US dollar's surge against the euro also was a factor in pushing down oil prices by making crude more expensive for investors trading in the weakening currencies.
