Oil prices hovered near $86 a barrel today in Asia as traders eyed whether a massive crude spill in the Gulf of Mexico would slow imports to the US.
Benchmark crude for June delivery was down 9 cents to $86.06 a barrel at midday Singapore time in electronic trading on the New York Mercantile Exchange. The contract rose 98 cents to settle at $86.15 on Friday.
Some analysts expect the 30-mile (48-kilometre) oil slick caused by as much as 210,000 gallons (795,000 litres) of crude gushing into the Gulf each day could undermine imports to key Louisiana terminals, helping to lower crude inventories and boost prices.
US authorities have said imports have not yet been affected.
"The potential disruption of oil tanker traffic in the Gulf of Mexico is already having an impact on oil prices". Goldman Sachs said in a report. "Traffic of oil service boats and oil tankers through the Gulf will likely be slowed".
Oil is near an 18-month high of $87, last touched in early April.
Investors are also mulling a recent jump of US crude supplies, a sign demand hasn't rebounded along with the overall economic recovery.
"The past two weeks have brought weak US oil inventory data that puts into question the much stronger macroeconomic data," Goldman said.
Goldman said it expects prices to rise to $94.50 a barrel in three months and to $99 a year from now.
In other Nymex trading in May contracts, heating oil fell 0.27 cent to $2.312 a gallon, and gasoline slipped 0.57 cent to $2.3937 a gallon. Natural gas jumped 2.0 cents to $3.940 per 1,000 cubic feet.
In London, Brent crude was down 8 cents at $87.36 on the ICE futures exchange.
