Oil prices rose on Tuesday as the United States and Europe planned new sanctions to punish Russia over alleged war crimes in Ukraine, raising concerns over tighter global supply, while Iran's nuclear talks with world powers stalled.
Brent crude was up $1.17, or 1.1%, to $108.70 a barrel at 0952 GMT. U.S. West Texas Intermediate was up $1.15, or 1.1%, at $104.43.
"With the European Union working on new sanctions that may target Russia’s oil industry, crude prices could edge up in the near term," said FXTM analyst Lukman Otunuga.
The West is planning new sanctions against Russia over civilian killings in Ukraine, with U.S President Joe Biden's national security adviser saying that new U.S. sanctions against Moscow would be announced this week.
There were mounting expectations that Europe would take action to reduce transactions with Russia's energy sector, further squeezing supplies, said OANDA senior analyst Jeffrey Halley.
To calm oil prices, U.S.-allied countries agreed last week to a coordinated oil release from strategic reserves for the second time in a month. However, Japanese industry minister Koichi Hagiuda on Tuesday said that the International Energy Agency (IEA) was still examining details of the release.
Oil prices jumped by more than $2 after his comments.
Ole Hansen, head of commodity strategy at Saxo Bank, expects oil prices to trade between $90 and $120 a barrel during the second quarter.
"Key events that could trigger additional uncertainty remain the prospect for an Iran nuclear deal, Venezuela being allowed to increase production and, not least, an increase in U.S. shale oil production," he said.
The United States still believes there is an opportunity to overcome the remaining differences with Iran in talks over its nuclear program, State Department spokesman Ned Price said on Monday.
Any signs that the United States and Iran are moving closer to a nuclear deal, which would return up to 1.3 million barrels per day of Iranian oil to global markets, would weigh on oil prices, BCA research said.
The end of the refinery maintenance period in Europe also lent some support to oil prices, analysts said, because it will allow higher crude intake.
