Iran’s Control of the Strait of Hormuz Likely Keeps Oil Flows Below Pre-War Levels

Core Event: Limited Oil Transit After the Iran-Israel-U.S. Conflict
In February 2026 the United States and Israel launched a war against Iran. In response, Iran’s Revolutionary Guard effectively closed the Strait of Hormuz, the world’s most critical oil chokepoint. Western commercial vessels now face the prospect of violating U.S. sanctions if they coordinate with Iranian authorities, prompting shipowners to reassess the risk of navigating the strait. Analysts expect that even a cease-fire will leave Iran exercising “operational control and influence” over Hormuz, curbing the volume of oil that can pass through the waterway.
Background & Context: Lessons from the Red Sea Crisis
The Red Sea disruption that began in November 2023, when Iran-aligned Houthi militants attacked commercial ships, showed how a relatively modest naval threat can halve traffic through a chokepoint for years. Although Houthi attacks have ceased, traffic through the Bab el-Mandeb Strait remains well below 2023 levels, underscoring the difficulty of restoring normal flows after a maritime crisis.
Key Figures & Groups

- Helima Croft – head of global commodity strategy, RBC Capital Markets.
- Richard Meade – editor-in-chief, Lloyd’s List.
- Tomer Raanan – maritime-risk analyst, Lloyd’s List.
- Jack Kennedy – head of Middle East country risk, S&P Global Market Intelligence.
- Saudi Arabia and United Arab Emirates – operating pipelines that divert millions of barrels per day away from Hormuz.
Data & Statistics
- Prior to the war, roughly 20 % of global oil and liquefied natural gas transited the Strait of Hormuz.
- Analysts project post-conflict traffic to settle at 60 %–70 % of pre-war volumes.
- Saudi and Emirati pipelines now carry “millions of barrels per day” to Red Sea and Gulf of Oman terminals, partially offsetting the shortfall but not fully compensating for lost Hormuz flows.
Why It Matters: Global Energy and Price Risks
The reduced throughput threatens to tighten world oil supplies, a factor already reflected in market pricing that assigns a 6.5 % probability of normal traffic by mid-June. Analysts warn that persistent supply constraints could lift WTI crude prices and heighten volatility in energy markets.
Official Statements & Responses
U.S. and regional officials acknowledge Iran’s de facto control of Hormuz and stress that any lasting resolution will require security guarantees for commercial vessels. Shipping analysts emphasize that a “permanently bifurcated strait” would tie access to political alignment rather than freedom of navigation, raising long-term strategic concerns for global trade.
Criticism & Opposition
Critics highlight the security hazards of a split navigation regime, including the risk of naval mines and the possibility of renewed hostilities if Iran’s nuclear and missile programs remain unresolved. They argue that without a comprehensive diplomatic settlement, shipowners may continue to avoid Hormuz, further depressing traffic.
Conflicting Reports & Gaps
Estimates of future traffic vary: some forecast a gradual return to 60 %–70 % of pre-war levels, while others note the absence of concrete timelines for mine clearance and for a durable U.S.–Iran agreement. No consensus exists on when, if ever, full pre-war volumes will resume.
Verbatim Quotes
- “No matter what happens, the Iranians will control the Strait of Hormuz for the foreseeable future,” — Amos Hochstein, former senior energy adviser to President Joe Biden
- “Any end to the conflict that leaves Iran exercising operational control and influence over the Strait will result in appreciably lower flows through the waterway in our view,” — Helima Croft, RBC Capital Markets
- “This doesn't trigger a recession in the way that some of the doomsday scenarios that we've talked about before might suggest, but it does not allow the prewar rebound,” — Richard Meade, Lloyd’s List
- “you don't need a massive navy in order to create major disruption in a maritime chokepoint,” — Tomer Raanan, Lloyd’s List
- “And there is a severe risk that the war could resume over the next year unless a permanent resolution is found to Iran's nuclear and ballistic missile programs, Kennedy said.” — Jack Kennedy, S&P Global Market Intelligence
What’s Next: Diplomatic and Maritime Monitoring
Stakeholders will watch for U.S. Navy safety announcements, OPEC statements on shipment stability, and diplomatic moves involving Hossein Salami and Lloyd Austin. Changes in maritime insurance rates, International Maritime Organization directives, or new bilateral agreements with Iran could further shape the trajectory of Hormuz traffic.
