PERTH, April 19 (Reuters) - Oil prices sank to a three-week low of below $82 a barrel on Monday, extending the previous session's 2.7-percent decline, as risk appetite soured across the board after investment bank Goldman Sachs <GS.N> was charged with fraud.
Goldman, which has large positions across many markets including commodities, was charged with fraud by the U.S. Securities and Exchange Commission (SEC) over its marketing of a subprime mortgage product. The news dragged down broad U.S. equity indexes. [
]The banking powerhouse also saw pressure building on both sides of the Atlantic on Sunday, with Germany and the U.K. saying that they will seek details from the SEC about Goldman's activities as a prelude to potential legal steps following a U.S.-led fraud investigation. [
]U.S. crude for May delivery <CLc1> fell $1.44 to $81.80 by 0146 GMT, after having dropped as low as $81.73 -- the lowest since March 29. The contract already fell 2.65 percent on Friday, the largest one-day percentage loss since Feb. 5.
London Brent crude fell $1.21 to $84.78.
"We are seeing a spillover reaction to news of Goldman being charged," said David Moore, an analyst at the Commonwealth Bank of Australia in Sydney.
"It's mainly a sentiment issue; oil prices have risen very strongly in recent weeks on bullish sentiments and anticipation of a demand recovery later this year. So it is naturally very vulnerable to a correction when market sentiments change."
Goldman has vowed to defend itself.
