July 16 (Reuters) - Oil prices ‌rose over 1% ​on Thursday ​as concerns over Middle East energy supplies increased after Iran asked Yemen's Houthis to stand ready to close the Red Sea oil route.

Brent crude futures were up 88 cents, ‌or 1.04%, to $85.83 a barrel at 1237 GMT, while U.S. West Texas Intermediate futures ⁠were up 94 cents, or 1.18%, to $80.54 a barrel.

"Simultaneous disruptions affecting Hormuz and Bab el-Mandeb would significantly amplify supply chain stress, ‌increase tanker availability constraints, and raise ‌insurance premiums," said Wael Makarem, financial markets strategist lead at Exness.

Iran has asked Yemen’s Houthi movement to stand ready to close the Red Sea oil route if the United States strikes Iranian power ​infrastructure, three sources told Reuters on Thursday, posing a potent new threat to global energy supplies.

Closure of the Bab el-Mandeb strait — gateway to the Red Sea — would open a new front in the ⁠energy crisis and Iran's overarching conflict with the U.S.

Total volumes of petroleum transiting Bab el-Mandeb amounted to 7.4 million barrels per day in ​June, or about 7% of global oil output, according to Kpler data, up from 4.2 million bpd last year.

The U.S. struck Iran's coastal defences and missile sites ​on Wednesday after reimposing a naval blockade of its ‌ports, while Tehran threatened to shut off more regional energy exports, saying it was engaged in an "existential war" with America.

The escalation comes after a fragile truce reached ⁠in June collapsed, reviving fears of a return to full-scale conflict and disrupting energy flows through the Strait of Hormuz, which handled about a fifth of daily global oil and LNG trade before the war began.

Fewer vessels passed through ⁠the strait on Wednesday, the first day after the U.S. reimposed its naval blockade on Iran. Seven crossed on Wednesday, ​down from 13 the previous day.

"It seems reasonable that prices could continue to climb towards $90-$95 and maybe even touch the $100 mark again and that is because the Strait of Hormuz is repeatedly being disrupted, creating uncertainty over oil flows from ‌the Gulf," said Ole Hvalbye, market analyst at SEB Research.

Oxford Economics said the likeliest scenario was that low, fluctuating levels of traffic through the strait spark ‌intermittent oil price rallies that keep average prices above $80 per barrel for several quarters.

Elsewhere, Ukraine's Security Service said on ⁠Thursday that together with Ukraine's navy it ‌has struck two Russian "shadow fleet" ​tankers with naval drones in the Black Sea.
