Reuters - Asian shares slipped on Monday, weighed down by underperforming Chinese stocks, while oil prices rallied on news the United States is likely to ask all importers of Iranian oil to end their purchases or face sanctions.

Brent and U.S. crude futures surged to nearly six-month highs on news reports that U.S. Secretary of State Mike Pompeo will announce “that as of May 2, the State Department will no longer grant sanctions waivers to any country that is currently importing Iranian crude or condensate.”

The potential disruption to Iranian supplies are expected to add to an already tight oil market.

“The U.S. chief Iran hawks indeed have the President’s ear as (Secretary of State) Pompeo and (National Security Advisor) Bolton are singularly focused on bringing Iran’s economy to its knees,” said Stephen Innes, head of trading at SPI Asset Management.

“Predictably oil prices are rising,” he said.

Following the Good Friday holiday, markets in Britain, Germany and France will remain closed for Easter Monday, while those in the United States will reopen.

The dollar was steady at 111.925 yen.

The Australian dollar, sensitive to shifts in risk sentiment, inched down 0.25 percent to $0.7137.

The U.S. reimposed sanctions in November on exports of Iranian oil after President Donald Trump unilaterally pulled out of a 2015 nuclear accord between Iran and six world powers. Washington is pressuring Iran to curtail its nuclear program and stop backing militant proxies across the Middle East.

Crude extended gains from last week, when a drop in crude exports from OPEC’s de facto leader, Saudi Arabia, and a draw in U.S. drilling rigs and oil inventories supported prices. [O/R]
