WTI crude extended gains for a fourth day as geopolitical tensions in the Strait of Hormuz persist, with fighting ongoing, a reported Iranian tanker seizure, and the end of the US-Iran ceasefire. The strait's continued closure and US diesel inventories near 23-year lows heighten supply concerns, while rising inflation fears and borrowing costs add to market unease.

WTI crude oil is extending gains as geopolitical tensions in the Strait of Hormuz escalate, with Iran seizing a tanker, attacking a cargo ship, and threatening to keep the strait closed unless US demands are met. The end of the US-Iran ceasefire and ongoing fighting have heightened supply disruption risks, while US diesel reserves sitting near 23-year lows add to concerns about tightness. These factors are keeping oil prices under upward pressure.
Fighting and shipping disruptions in the Strait of Hormuz have driven WTI crude to a fourth day of gains, with Iran seizing a UAE-linked tanker and attacks on cargo ships.

US diesel reserves near 23-year lows also factor into the market's focus on supply constraints.
