Oil prices edged higher on Wednesday on supply concerns with the U.S. stepping up efforts to limit Venezuelan and Iranian oil exports, while a bigger-than-expected drop in U.S. crude inventories also lent support. Brent crude futures gained 20 cents, or 0.3%, to $73.22 a barrel by 0404 GMT, while U.S. West Texas Intermediate crude futures rose 20 cents, or 0.3%, to $69.20 a barrel. Both contracts hit their highest in three weeks in the previous session. “Crude oil prices maintain their bullish bias after Trump’s sanctions on Venezuelan oil, raising supply-side concerns,” Priyanka Sachdeva, a senior market analyst at Phillip Nova, wrote in a market commentary on Wednesday. On Monday Trump signed an executive order authorizing his administration to impose blanket 25% tariffs under the 1977 International Emergency Economic Powers Act on imports from any country that buys Venezuelan crude oil and liquid fuels. Oil is Venezuela’s main export. China, already a target of U.S. import tariffs, is its largest buyer. Trade of Venezuelan oil to top buyer China stalled on Tuesday, as Chinese traders and refiners said they were waiting to see how the order would be implemented and whether Beijing would direct them to stop buying. Oil rises for fifth day on supply concerns Washington last week also imposed a new round of sanctions on Iran’s oil sales targeting entities including Shouguang Luqing Petrochemical, a “teapot,” or independent refinery in east China’s Shandong province, and vessels that supplied oil to such plants in China, the top buyers of Iranian crude. The market was also buoyed by American Petroleum Institute data that showed U.S. crude inventories fell by 4.6 million barrels last week, a sign of healthy demand for fuel in the world’s largest economy. Analysts polled by Reuters were expecting a decline of 1 million barrels. Official U.S. government data on crude inventories is due on Wednesday. The upswing in oil prices is a temporary phenomenon, with the potential economic slowdown due to Trump’s tariffs keeping a lid on price gains, Phillip Nova’s Sachdeva said. Further capping oil prices, the U.S. reached deals with Ukraine and Russia to pause attacks at sea and against energy targets, with Washington agreeing to push to lift some sanctions against Moscow. Kyiv and Moscow both said they would rely on Washington to enforce the deals, while expressing scepticism that the other side would abide by them.
