LONDON, April 18 (Reuters) - Oil fell more than $2 a barrel on Friday after a surge to new record highs this week, pressured partly by worries about a possible slowdown in China, the world's second biggest energy consumer.
U.S. light crude <CLc1> fell $2.07 to $112.79 a barrel by 1230 GMT. It set a record high of $115.54 on Thursday.
London Brent crude <LCOc1> was down $1.62 at $110.81. It struck an all-time peak of $113.38 on Thursday.
A sharp fall in China's stock market on Friday could herald the start of a slowdown in the Chinese economy, whose rapid expansion has been one of the main factors driving oil prices to all-time highs this year, analysts said. [
]"The market is a little bit on the defensive. The Chinese stock market is very weak and it looks as if that pressages an economic slowdown in China, which would be bearish for oil," said Christopher Bellew of Bache Financial.
China's stock market fell nearly 4 percent to a 12-month closing low as the biggest stock, PetroChina <601857.SS> dropped for the first time below its price in last October's Shanghai initial public offer.
The Chinese market has been gripped by a downward trend for six months, triggered by high inflation and worries of a threatened economic slowdown later in the year.
Despite these fears, data from China this week showed continued large import volumes of distillates to meet domestic demand.
An unexpected fall in gasoline inventories in the United States, the world's largest energy consumer, was the trigger for this week's price rise ahead of peak summer driving demand.
LONG-TERM DRIVERS
The long-term drivers for investment in the oil market are tight spare production capacity, slow output growth from non-OPEC producers while robust demand from emerging economies is more than compensating for declining demand from industrial nations.
"Market balances continue to look tight, owing to persistent poor non-OPEC production growth and steady demand increases. On the demand side Chinese consumption is improving, more than making up for weak OECD demand," said Barclays Capital.
Bellew noted there were signs of increased speculative funds coming into the oil market.
The premium for U.S. crude, which attracts most speculative investment, over Brent rose to $2.06 on Friday, up from a low of $1.52 in the previous session.
Oil's record run comes as the flow of investment across commodities shows no sign of abating.
U.S. rice futures extended record highs on Friday and corn was nearing its high. [
