(Updates comment and prices)
LONDON, March 20 (Reuters) - Brent crude oil eased on Thursday after the Federal Reserve indicated the U.S. central bank could end its stimulus programme and raise interest rates sooner than expected.
In comments that sent stocks and bonds tumbling, Fed Chair Janet Yellen on Wednesday said the bank would probably end its massive bond-buying programme this autumn, and could start raising interest rates around six months later.
While the announcement suggested policymakers are becoming more confident that the world's largest economy and top oil consumer can stand on its own feet, such a shift would drain the cheap liquidity that has boosted commodities.
"A general lack of monetary stimulation of growth may be seen as a negative fundamental for oil in the long-term, grand scheme of things," said Tony Machacek, a broker at Jefferies Bache.
Machacek added that a strong dollar, boosted by the Fed announcement, as well as ample global supplies of oil contributed to the bearish sentiment.
Brent was down 11 cents at $105.74 a barrel by 1357 GMT, after settling 94 cents lower on Wednesday.
U.S. crude traded 42 cents lower at $99.95 a barrel. The April contract, which expires on Friday, had closed 67 cents higher on Wednesday after data showed a drop in crude inventories at the Cushing, Oklahoma hub.
Stocks at Cushing fell 989,000 barrels last week, down for a seventh straight week as a TransCanada Corp pipeline continued to drain oil to the Gulf Coast, where stocks rose 4.7 million barrels to the highest level yet this year, data from the U.S. Energy Information Administration showed.
But total U.S. oil stocks rose for a ninth week, soaring nearly 6 million barrels or more than double forecasts as refinery utilisation rates fell to the lowest in nearly a year.
"We believe that the previously-ample stocks at Cushing are predominantly being moved to - rather than being consumed on - the Gulf Coast, with consequently limited impact on overall crude stocks," BNP Paribas analysts said in a note.
Oil prices drew some support from tensions between Ukraine and Russia, the world's biggest oil producer.
The United States warned that Moscow was on a "dark path" to isolation on Wednesday as Russian troops seized two Ukrainian naval bases, including a headquarters in the Crimean port of Sevastopol.
The dramatic seizure came as Russia and the West dug in for a long confrontation over Moscow's annexation of Crimea, with the United States and Europe groping for ways to increase pressure on a defiant Russian President Vladimir Putin.
Societe Generale cut its 2014 price forecast for crude oil on Wednesday, saying prices have underperformed despite strong fundamentals.
Societe Generale reduced price targets for Brent to $106 per barrel from $108 and for U.S. crude to $96 per barrel from $99.
