Singapore - World crude oil prices inched lower in Asian trade on Wednesday after soaring overnight amid tensions between oil-producing Iran and the United States, analysts said.
New York's main contract, West Texas Intermediate (WTI) for delivery in February, dipped 36 cents to $102.60 after surging $4.13 in US trade.
Brent North Sea crude for February shed 32 cents to $111.81 after rallying $4.75 in London the day before.
"There has been a little bit of slowing across commodities after the rise yesterday. But the situation with Iran remains worrisome," said Nick Trevethan, senior commodities strategist at ANZ Research.
"The consequences of any military action in the Middle East will be enormous. A spike in crude prices will kill off any recovery in the US," he added.
Iran has threatened to choke off shipping or go after American naval ships if Western governments implement the latest round of punitive sanctions over its nuclear programme.
Its military warned on Tuesday that it would not allow a US aircraft carrier to return through the Strait of Hormuz.
But the United States has insisted that it has no plans to pull warships from the region and has dismissed Tehran's threats as those of a weakened, isolated regime.
A military confrontation between the United States and Iran could see crude oil prices hit the $200 mark, Trevathan said.
The Strait of Hormuz is a vital waterway in the Middle East through which 20% of the world's oil is transported.
