April 30 (UPI) -- Oil prices briefly topped $126 a barrel in Asian trade overnight as markets reacted to news the United States might resume its military offensive against Iran and fears the Hormuz Strait might remain closed for much longer than anticipated.

Brent crude, the global benchmark, surged to $126.31, its highest level since Russia invaded Ukraine in 2022, after a report that U.S. military commanders were pitching a campaign of "short and powerful" strikes to U.S. President Donald Trump, to force Iran back to the negotiating table.

The price retreated to around $120 by the time markets in Europe opened on Thursday and continued to fall through the morning. The Brent contract for June delivery was trading at $113.91 a barrel in mid-afternoon trade in London, while American crude for June delivery was changing hands at $104.82.

Oil prices have already elevated since the war began on Feb. 28 and began climbing further on Wednesday after Trump met with executives of U.S. oil companies the previous day about how to deal with supply disruption from the closure of the Strait of Hormuz by Iran, which has vowed it will continue until the United States' blockade of its ports is lifted.
