Brent and WTI crude oil prices rose 3.95–4.17 USD/barrel on August 10 due to uncertainty over the Strait of Hormuz reopening. Iran's Foreign Minister confirmed no direct talks with the US until demands (sanctions relief, military threat cessation, interim agreement compliance) are met. Oil supply concerns intensified as Houthi militants attacked Saudi Aramco's Jazan refinery for the second time (August 9), and Ukrainian forces continue targeting Russian energy infrastructure, including the Taneco refinery. These geopolitical tensions are driving near-term crude volatility and supply-chain risk.
