Brent crude oil futures slipped to around $66.5 per barrel on Thursday, on track for a six-day losing streak, as hopes for a diplomatic resolution to the war in Ukraine pressured prices. The Kremlin confirmed that Russian President Vladimir Putin will meet US President Donald Trump in the coming days, marking their first summit since 2021 and raising expectations for de-escalation. This news weighed on prices despite supportive fundamentals, including a larger-than-expected 3 million barrel draw in US crude inventories. Meanwhile, Trump imposed a new 25% tariff on Indian goods over continued Russian oil imports and signaled the possibility of additional tariffs on China. Saudi Arabia also raised its September crude prices for Asian buyers for a second consecutive month, citing tight supply and strong demand. However, global economic uncertainty and shifting geopolitical dynamics capped any potential upside in oil markets.
