Oil fell in Asian trade today on concerns demand from quake-hit Japan would be affected, analysts said.
New York's main contract, light sweet crude for delivery in April, dipped $1.28 to $99.88 per barrel. Brent North Sea crude for April delivery lost $1.39 to $112.45.
"In the short term, there might be some demand disruptions due to the Japanese earthquake, but there will be an increase in fuel oil imports due to the lost nuclear power capacity, which will be supportive of fuel oil prices in the near term," said Chen Xin Yi, commodities analyst for Barclays Capital.
Crude futures fell immediately last week in reaction to Friday's massive 8.9-magnitude earthquake off Japan, unleashing a tsunami that battered the country's northeast coast and stretched across the Pacific.
Traders worry the disaster will affect energy consumption in Japan, the world's third largest economy.
Tokyo shares fell sharply in opening trade today as investors remained jittery over the economic consequences from the biggest earthquake in Japan's history and the devastating tsunami.
Shares fell 5.42% in a post-quake sell-off as the key index sank below 10,000 to its lowest levels since November.
The Nikkei index fell 556.06 points shortly after opening to 9,698.37.
Meanwhile, investors are also keeping a nervous eye on the unrest in Libya where rebels continue to battle forces loyal to leader Moamer Kadhafi.
Qatar's Energy Minister Mohammed Saleh al-Sada had said on Sunday that the world oil output was sufficient despite the unrest in Libya which had slashed the country's crude production.
Libya was producing 1.69 million barrels per day (bpd) before the unrest, according to the International Energy Agency. Of this 1.2 million bpd was exported, mostly to Europe but with China and the United States also major customers.
Oil giant Total said on Friday that the unrest has cut Libya's output by 1.4 million bpd to under 300,000. The price of oil on world markets has soared since the mid-February outbreak of the anti-government uprising.
