LONDON, April 28 (Reuters) - Oil fell for the third straight session on Wednesday, taking losses this week to 4 percent on excess crude supplies in the United States and widespread fears a possible debt default in Greece could derail the recovery.
A day after ratings agency Standard & Poor's cut Greece's credit rating to junk status and downgraded Portugal, investors continued to pull cash out of risky investments such as energy.
The severity of the sovereign debt crisis saw one of the most common measurements of market volatility, the Chicago Board Options Exchange Volatility Index <.VIX> or 'fear index', jump to its highest level since the immediate aftermath of the Lehman Brother's collapse in late 2008.
"Market sentiment remains fragile and there is a possibility that if we have more adverse economic news, we could see prices decline further," said David Moore, an analyst at the Commonwealth Bank of Australia.
"U.S. oil demand is weak. Over the course of this year we may see inventories decrease a bit, but overall they will probably remain relatively high."
U.S. crude for June delivery <CLc1> fell to a low of $81.29, before paring losses to trade down 20 cents at $82.24 by 1126 GMT. Prices are down about $3 since Friday's close.
European shares slumped to a seven-week low on Wednesday while the euro hit a one year-low against the dollar, further pressuring commodity prices, before bouncing to trade slightly higher on the day.
Oil and other dollar-denominated commodities tend to move in the opposite direction to the greenback as a weaker dollar makes them cheaper for other currency holders and vice versa.
RISING U.S. CRUDE STOCKS
Crude inventories in the United States rose 5.3 million barrels in the week ended April 23, the American Petroleum Institute (API) said on Tuesday. [
]The gain was more than five times the number forecast by a Reuters poll of oil analysts, aided by soaring stockpiles at the delivery point of the main U.S. crude futures contract.
Stocks at Cushing, Oklahoma rose by 401,000 barrels last week to 34.6 million barrels, close to the record high 35.4 million barrels reported by the industry-funded API on Jan. 1.
The oil glut in the U.S. Midwest is creating distortions in oil futures markets. The front-month U.S. crude contract, which usually trades at a premium to European benchmark ICE Brent futures, was almost $3.60 lower, its biggest discount in eight months. June Brent was down 31 cents at $85.47 a barrel. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ For a graphic of Brent futures against U.S. crude, click on: http://link.reuters.com/hyf69j and for story click: [

]U.S. retail gasoline demand dropped 2.7 percent in the week to April 23 from the previous week, according to a MasterCard SpendingPulse report on Tuesday. Year-on-year, U.S. gasoline demand fell 1.9 percent, the report said. [
]Demand in developed economies is expected to barely grow or even fall in 2010, but rapid growth in emerging markets should still see global consumption rise by around 1.7 milllion barrels next year, according to the International Energy Agency. [
]Rising global demand has supported oil prices, benefiting oil majors like Royal Dutch Shell Plc <RDSa.L> and BP <BP.L>. <BP.N>, which have both posted better-than-expected first-quarter results in the last two days. [
