Oil firm as Iran sanctions loom, but US seeks to prevent supply shortfall

By Henning Gloystein

SINGAPORE (Reuters) - Oil was steady on Tuesday, supported by looming U.S. sanctions against Iran's petroleum industry.

But prices were capped by signs that increased supplies by other major producers, including the United States and Saudi Arabia, could make up for the disruptions from Iran.

U.S. West Texas Intermediate (WTI) crude futures were at $67.61 per barrel at 0112 GMT, up 7 cents from their last settlement.

Brent crude futures climbed 11 cents to $77.48 a barrel.

"It was a mixed performance in the crude oil market," said ANZ bank in a note, pointing to Washington's sanctions against Iran's oil exports that will be enforced from November.

Washington is putting pressure on other countries to also cut Iran imports, with close allies like South Korea and Japan, but also India, showing signs of falling in line.

ANZ bank said prices were capped "amid speculation later in the day that Saudi Arabia and Russia will fill any gap."

U.S. Energy Secretary Rick Perry met with Saudi Energy Minister Khalid al-Falih on Monday in Washington, the U.S. Energy Department said, as the Trump administration encourages big oil-producing countries to keep output high ahead of the renewed sanctions.

Perry will also meet with Russian Energy Minister Alexander Novak on Thursday in Moscow.

Russia, the United States and Saudi Arabia are the world's three biggest oil producers by far, meeting around a third of the world's almost 100 million barrels per day (bpd) of daily crude consumption.

Combined output by these three producers has risen by 3.8 million bpd since Sept. 2014, more than the peak 3 million bpd Iran has managed during the last three years.

BIG U.S. DISCOUNT

With Middle East crude markets tightening because of the U.S. sanctions against Iran, many Asian refiners are seeking alternative supplies, with South Korean imports of U.S. crude likely hitting a record in November.

At the same time, American oil producers are seeking new buyers for crude they used to sell to China before orders virtually dried up because of the trade disputes between Washington and Beijing.

Traders said this pulled wide open the discount of U.S. WTI crude versus Brent to almost $10 per barrel, the biggest since June.
