(Recasts with news of larger Greece rescue package)
By David Sheppard
LONDON, April 28 (Reuters) - Oil reversed early losses on Wednesday to climb towards $83 a barrel on news Greece will soon receive extra help in servicing its debts, the day after Athens credit rating was cut to junk.
At one stage on Wednesday, crude oil losses for the week totalled almost 5 percent on the back of mounting crude supplies in the United States and fears a possible debt default in Greece could derail the recovery.
But news a larger joint eurozone and International Monetary Fund aid package for Greece was imminent saw prices reverse. [
]U.S. crude for June delivery <CLc1> fell to a low of $81.29, before paring losses to trade up 29 cents at $82.73 by 1336 GMT. Prices are down by more than $2 so far this week.
London Brent for June delivery <LCOc1> was down 16 cents at $85.62 a barrel.
"It's likely that the only thing that will be easy to predict in the oil market today will be volatility," said MF Global analyst Tom Pawlicki.
"The negative side (is) focusing on yesterday's break of the 50-day moving average, ongoing worries about Greek debt, and an increased likelihood of position limits and financial regulation. The positive side will cling to the belief that investment can be maintained and save the market from falling."
In the past two days, oil prices have twice fallen below the 50-day moving average, a key technical indicator that often proves a battleground for optimists and pessimists in the market. The 50-day moving average is currently at $82.10.
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 on Tuesday to its highest level since the immediate aftermath of the Lehman Brother's collapse in late 2008.
European shares fell to a seven-week low on Wednesday while the euro hit a one year-low against the dollar before bouncing to trade 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.
The euro rose to the day high against the dollar on optimism Greece will soon receive assistance with servicing its debts.
RISING U.S. CRUDE STOCKS
"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."
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 amount 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 lower. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ For a graphic of Brent futures against U.S. crude, click on: http://link.reuters.com/hyf69j and for story click: [
