UPDATE 4-Oil slips below $100 on demand worries, firm dollar
* Brent hits lowest in three weeks
* Stronger greenback drags on oil benchmarks
* Doubts over U.S., China demand growth hurt
(Updates, previous dateline SINGAPORE)
LONDON, June 24 (Reuters) - Brent crude dropped below $100 per barrel on Monday, for the first time in three weeks, pressured by a stronger dollar and concerns about demand from top oil consumers the United States and China.
The international benchmark tumbled nearly 5 percent last week in its biggest weekly drop since early April after Federal Reserve Chairman Ben Bernanke laid out a strategy for paring monetary stimulus, broadly sapping demand for commodities.
"Comments on tapering by the Fed along with poor flash PMI figures and tight liquidity in China are driving a steep correction in risky assets globally," according to a Morgan Stanley research note.
"Commodities have faced additional pressure from the resulting rally in the U.S. dollar."
Brent crude was off 6 cents at $100.85 by 0944 GMT, after falling to $99.82 - its weakest since June 3. U.S. oil slipped 13 cents to $92.56 a barrel.
The stronger dollar hurts commodities priced in the greenback, including copper and gold, by making them more expensive for holders of other currencies.
U.S. oil is expected to revisit its April 18 low of $85.61 a barrel over the next three months, with a good chance of dropping through this level towards the June 28, 2012 trough of $77.28, according to Reuters market analyst Wang Tao.
The 3-month outlook on Brent shows a rapid drop to its June 22 low of $88.49 a barrel.
CHINA DEMAND WORRIES
A dimming outlook for oil demand growth in China, the world's second-largest economy, also dragged on prices.
Manufacturing activity dipped to a nine-month low in June, raising fears the country could miss its growth target of 7.5 percent for this year, a preliminary survey showed last week.
"Given the grave concerns about the Chinese economy, oil bulls are running for the exit," oil brokerage PVM said in a note to clients.
"This week has not started in an upbeat mood and the chances of further misery are a real possibility unless the Chinese central bank quickly intervenes."
Earlier this month, the International Energy Agency lowered its 2013 oil demand growth forecast for China to 3.8 percent from 3.9 percent.
