 NEW YORK, Oct 19 (Reuters) - Oil fell more than 4 percent
to below $80 a barrel  on Tuesday, the biggest drop in more
than eight months, as China hiked interest rates to cool its
booming economy.
                                
 China's rate rise, its first since 2007, is aimed at
curbing inflation and raised concerns about demand growth for
commodities and strengthened the dollar.
                                
 "This dollar-driven move has pulled down prices across the
board in the oil markets," said Tom Knight, a trader at Truman
Arnold in Texarkana, Texas.
                                
 U.S. crude for November <CLc1> delivery fell $3.59, or 4.32
percent, to settle at $79.49 per barrel, the biggest one-day
percentage dive since early February.
                                
 A day ahead of the U.S. November contract's expiration and
before release of U.S. oil inventory data that is  expected to
show stockpiles rose last week, U.S. December crude <CLc2> also
dropped more than 4 percent, settling at $80.16 a barrel.
                                
 Trading volume was near 790,000 lots on Tuesday afternoon,
just above the 30-day average of 768,063 lots, according to
Reuters data.
                                
 In London, ICE Brent December crude <LCOc1> fell $3.27, or
3.88 percent, to settle at $81.10 a barrel.
                                
 The specter of China's dynamic economic growth slowing
pressured oil and other commodity prices and sent investors to
the safe-haven dollar to cut risk exposure. The inverse
correlation of the dollar index <.DXY> and oil prices rose to
the highest in about a month.
                                
 The dollar had already received lift late  on Monday from
comments by U.S. Treasury Secretary Tim Geithner that the
United States would not engage in competitive currency
devaluation. [ID:nN18291636]
                                
 A stronger dollar can pressure oil prices by making
dollar-denominated oil more expensive to users of other
currencies and by pulling investment into foreign exchange
markets from commodities that are viewed as riskier bets.
                                
 "(The Chinese rate move) could imply a little bit of softer
growth in commodities demand," said UniCredit's Jochen
Hitzfeld.
                                
 Copper retreated from 27-month highs on top metals consumer
China's interest rate hike. [MET/L] Gold also fell as investors
reacted to the stronger dollar. [GOL/]
                                
 Economic concerns sent U.S. equities lower on Tuesday, as
consumer-sensitive Apple <AAPL.O> and IBM <IBM.N> fell after
their results disappointed investors. [.N]
                                
 "(Crude) could rebound and make this up tomorrow for no
apparent reason. The fact that the market looks elsewhere and
not fundamentals shows that the premium associated with
exogenous elements will wax and wane and volatility will stay
with us," said Mike Fitzpatrick, vice president at MF Global in
New York.

 U.S. crude stockpiles were expected to have risen last

a.m. EDT (1430 GMT) on Wednesday.
                                
 Another measure of fundamentals was mixed  on Tuesday, as
MasterCard reported U.S. retail gasoline demand rose 2.7
percent last week from the prior week, but dipped 0.9 percent
from the year-ago period and was lower on a four-week average
than the same period in 2009. [ID:nNLLJLE6KS]
