US-Iran Talks Progress Sends Oil Prices Lower on Hormuz Optimism

US and Iran concluded a round of high-level talks in Switzerland on June 22, with both sides reporting "encouraging progress" toward a broader ceasefire and agreement to keep the Strait of Hormuz open.

Vice President JD Vance said the talks created a "good foundation for a successful final deal" and that a communication line for safe passage through the Strait was established. Mediators Qatar and Pakistan announced a 60-day roadmap toward a final deal, including a mechanism to keep the waterway open.

The diplomatic breakthrough reversed the war-driven oil price spike. Brent crude fell 1.5% to below $80 a barrel on June 22, and WTI crude, the US benchmark, traded well below the $75.99 threshold.

Oil prices had surged when Tehran blockaded the Strait of Hormuz earlier in the conflict, but an interim deal last week already pulled prices down. The next move for oil markets hinges on whether the 60-day roadmap holds and whether a final deal is reached. Any sign of a breakdown in talks or renewed tension could reverse the decline.
