Concerns that high interest rates will weigh on global economic growth appear to be resurging, overshadowing supply and demand trends in the oil market itself, sending oil prices lower. Several policymakers sounded hawkish on interest rates last week, with Lagarde saying on Tuesday that the ECB may not be able to call an end to its historic cycle of rate hikes anytime soon. The key time spread, which helps gauge the strength of the oil market, fell further into a bearish contango structure on Tuesday, pointing to a persistent oversupply. More broadly, futures have struggled to find direction since early May. Ole Hansen, head of commodity strategy at Saxo Bank, said: New York crude oil futures are still on track for the first consecutive quarterly decline since 2019, due in part to headwinds from the Fed's aggressive monetary tightening policy and strong Russian crude oil prices. Exports add to pressure on oil prices.
