Oil prices have surged due to intensifying conflict between the US and Iran over the Strait of Hormuz, a crucial shipping lane. Brent crude, the international benchmark, jumped $7.14, or 9.4%, to $83.15 a barrel, while West Texas Intermediate (WTI) climbed $6.68, or 9.35%, to $78.09. Gasoline futures also rose nearly 6%, and heating oil gained more than 8%. This significant increase in oil prices, described as nearly 10% on Monday, has alarmed investors about potential global supply shocks and reignited fears of inflation.

The renewed hostilities, including additional US military actions and a reinstated naval blockade targeting Iranian shipping, have heightened geopolitical uncertainty. Market analysts, such as Fabien Yip from IG and Mukesh Sahdev from XAnalysts, anticipate continued volatility with Brent prices likely remaining in the upper $70s during August and September. However, they believe a repeat of the earlier peak of nearly $120 a barrel is unlikely due to slow demand recovery and an already oversupplied market from OPEC+ output expansion and tanker releases.

This surge in crude prices has had a ripple effect across global financial markets. Wall Street stocks closed lower, and technology shares led the decline, while Treasury yields moved higher. Concerns are rising that higher energy costs could complicate central banks' plans for interest-rate cuts and negatively impact corporate earnings. Money markets are now pricing in approximately a 50% chance of a Federal Reserve rate hike in July, reflecting increased inflation expectations linked to the geopolitical developments. Saudi Aramco's CEO, Amin Nasser, also warned that prolonged disruption in the Strait of Hormuz could delay global oil market stability until 2027.
