Oil prices rose on Tuesday as investors covered short positions, although concerns over tariffs and U.S. monetary policy continue to impact fuel demand. Brent crude futures rose 0.6% to $66.68 a barrel, while the U.S. West Texas Intermediate crude contract for May was up 0.7% at $63.53 a barrel. Progress in U.S.-Iran nuclear talks and a potential nuclear deal could also impact oil prices and reduce supply concerns. However, concerns about a potential recession driven by the tariff war persist.
