Opening of the Strait of Hormuz after a US‑Iran agreement could lower gasoline prices within weeks
Executive summary: A US‑Iran diplomatic agreement scheduled for 19 June aims to reopen the Strait of Hormuz, a vital oil waterway. Reopening the strait could increase crude oil supply and gradually reduce gasoline prices, impacting consumer costs and inflation.
Who is involved: US and Iranian governments, oil traders, European energy markets, and policymakers.
Likely next: Gradual reopening of the strait over the coming weeks, with market monitoring of price responses and further diplomatic follow‑up.
The United States and Iran are set to sign an agreement on 19 June that would reopen the Strait of Hormuz, a key oil transit chokepoint. A reopened passage could increase crude supply and eventually depress gasoline prices, though effects are expected to be gradual. The development is being monitored by energy markets and policymakers. No immediate price change is guaranteed, but the prospect influences short‑term energy outlooks.
What's next — scenarios
Diplomatic Breakthrough (Base Case) (50%)
Energy markets stabilize as the risk premium on crude oil pricing diminishes, leading to moderate downward pressure on gasoline retail prices.

- Increased vessel traffic through the Strait of Hormuz
Geopolitical Stalemate (Downside) (30%)
Gasoline prices remain volatile and high due to continued maritime security concerns and lack of actual flow increases.
- Failure to sign agreement on 19 June
- Reported naval skirmishes in the Strait
Supply Glut Acceleration (Upside) (20%)
Rapid drop in gasoline margins for retailers as sudden crude availability outstrips refinery throughput capacity.
- Significant increase in Iranian crude export volumes
- OPEC+ decision to maintain production levels despite increased supply
