(Updates prices, adds comment)
LONDON, March 1 (Reuters) - Oil trimmed early gains to trade below $80 a barrel on Monday, pressured by a fall in sterling to its lowest in nine months against the dollar on worries over political uncertainty.
U.S. crude for April delivery <CLc1> fell 11 cents to $79.57 by 1224 GMT, after having climbed by as much as 96 cents. On Friday, the contract settled up $1.49 at $79.66 and posted its biggest monthly percentage gain since May 2009.
London Brent crude <LCOc1> rose 1 cent to $77.60.
"We're seeing the pound get absolutely hammered, and it has taken the shine off the oil market," said David Morrison, market strategist at GFT Global in London.
Sterling shed well over one percent against the dollar and the euro after a poll showed a growing risk that no party will win a majority in an election due by June 3.[
][ ]The British currency was on track for its largest one-day fall against the dollar since February 2009, while gold priced in sterling <XAUGBP=R> hit record highs.
"Because these markets are all so correlated ... they have all become traders' markets, and not investors' markets, and it's always with an eye on the dollar," Morrison said.
The dollar rose by almost 1 percent against a basket of major currencies. <.DXY>
COPPER COMMODITY
Oil rallied earlier on a combination of bullish sentiment and a rise in the price of copper futures following a massive earthquake on Saturday in Chile, the top producer of the industrially indispensable metal.[
]Chile's state energy company ENAP said it was boosting diesel imports after two of its oil refineries -- Aconcagua and Bio Bio with a combined capacity of 220,000 barrels, per day -- were damaged in Saturday's quake.
"Although these volumes are not large in a global context, this disruption is just another to add to a series of oil supply disruptions that have occurred recently, again, potentially hastening the tightening in oil fundamentals that has already begun," analysts at Goldman Sachs wrote in its Commodities Update.
FOREX FOCUS
The euro fell against the dollar on Monday, paring earlier gains made on the back of emerging signs that a support deal for Greece may be near. Commodities priced in U.S. dollars tend to become cheaper for holders of other currencies if the dollar declines. [
]Any progress towards an aid plan for Athens could boost the euro, as well as bond prices and banking stocks in Greece and other indebted countries on the euro zone's southern periphery.
But any rally by the euro might be brief, because investors would also worry that a dangerous precedent was being set for Germany and other rich states in the zone to take on the liabilities of poorer ones.
IRANIAN EXPORTS
On Sunday a senior military official from Iran, the world's fourth-largest exporter of crude, said the country could make European nations suffer by cutting off energy supplies and could target any adversary with its missiles.[
]Iran is disputing its nuclear energy programme with the United States and its allies, who say it is aimed at developing weapons. Tehran says it is only interested in power generation and medical research.
Oil traders will look to economic reports this week, with key focus on U.S. jobless data on Friday, that should give more clues on consumer spending.
Other economic indicators due include U.S. manufacturing on Monday and U.S. home loans on Wednesday.
Positive economic data on Friday from the United States, which saw the world's largest economy grow faster in the fourth quarter than initially thought, also helped increase investors' appetite for more risky assets, lending further support to oil.
