LONDON, July 3 (Reuters) - Oil jumped to record highs above $145 a barrel on Thursday as traders rushed to buy ahead of the long holiday weekend in the world's top consumer to mark U.S. Independence Day.
Expectation was high that a combination of a weak U.S. dollar, lower U.S. crude stocks and tension between Israel and major oil producer Iran would push prices to $150 before the close of trade, in line with a prediction made last month.
Investment bank Morgan Stanley, one of Wall Street's biggest energy traders, said on June 6 that crude could reach $150 by July 4.
U.S. crude <CLc1> rose to a high of $145.85 a barrel. It was trading $1.88 higher at $145.45 by 1042 GMT.
London Brent crude <LCOc1> hit an even higher peak of $146.69. It was trading $1.97 higher at $146.23.
Saudi Oil Minister Ali al-Naimi was more reluctant to make predictions.
Asked at a conference in Madrid whether oil would hit $150, he replied: "If I knew that, I'd be in Las Vegas."
He also said Saudi Arabia would pump more oil if there were demand for it, but that his customers were satisfied and that the market was driven by a range of factors, but not by any lack of supply.
One of those factors is the weakening U.S. dollar.
The currency was forecast to fall further when the European Central Bank announces what is expected to be its first rate rise in more than a year at 1145 GMT, potentially strengthening the euro against the dollar.
A weak U.S. dollar has helped to fuel this year's rally across dollar-denominated commodities as investors seek to hedge against inflation and falls in other asset classes.
Oil prices, which have been edging higher since the start of the week, gained momentum on Wednesday after U.S. government data showed a sharp fall in oil inventories.
Bullishness has been tempered slightly by evidence high oil prices have started to erode demand as U.S. gasoline prices have leapt to more than $4 a gallon.
But traders were reluctant to sell ahead of the U.S. Independence Day holiday, which marks the peak of the U.S. driving season, particularly in view of heightened tension between Israel and Iran.
Speculation has mounted Israel could launch an attack on Iran's nuclear plans, which Tehran has insisted are purely for peaceful purposes.
The market is concerned any conflict could disrupt oil shipments from the Gulf through the vital shipping route, the Strait of Hormuz.
Roughly 40 percent of the world's seaborne oil passes through the Strait. (Additional reporting by Chua Baizhen in Singapore)
