Shipping through the Strait has been largely blocked by Iran since February 28, 2026, following U.S.-Israeli strikes. Brief Iranian announcements of reopening (e.g., April 17) were quickly reversed, with traffic remaining minimal. The page details ongoing disruptions to ~20% of global LNG and oil flows.[1] - CNN: “94 days of paralysis: The Strait of Hormuz remains choked off” (cnn.com, published ~June 2, 2026)
President Trump has claimed reopening is imminent, but shipping executives refuse to risk vessels without a definitive U.S.-Iran peace deal. Commercial traffic stays near standstill levels after 94 days, with ~2,000 ships stranded. Renewed fighting undermines any progress.[2] - Reuters: “Three oil, LNG tankers exit Hormuz with transponders off” (reuters.com, published May 28, 2026)
A small number of vessels (including one LNG tanker) have exited “dark” (transponders off) in late May, heading to India/China, but overall oil and LNG traffic remains severely limited. The U.S.-Israeli war since Feb. 28 has curtailed normal flows (~125–140 daily passages pre-war). ~20,000 seafarers remain stranded.[3] - MobilityEnergy.com: “In all the darkness, traffic pulls Strait of Hormuz again” (mobilityenergy.com, published June 3, 2026)
Some oil and LNG ships are attempting passage by turning off transponders to evade Iranian surveillance, marking a gradual trickle after months of near-zero traffic. This follows the Feb. 28 conflict start and persistent Iranian restrictions. Full normal operations remain absent.[4] - Investopedia: “Iran Says the Strait of Hormuz Will Stay Closed…” (investopedia.com, published ~June 1, 2026 / “3 days ago”)
Iranian officials recently withdrew from peace talks and vowed to “completely block” the strait. Analyses differ on U.S. economic impacts, but the closure of this route for ~20% of global oil/LNG supply continues. No resolution to full reopening reported.[5] - Fortune: “The Strait of Hormuz is splitting into U.S. and Iranian lanes…” (fortune.com, published ~June 1, 2026 / “3 days ago”)
Limited “dark” traffic is emerging amid intensified fighting, but the strait has been effectively shut for three months. ~2,000 ships remain trapped; insurance and risks deter normal LNG/oil transits. Diplomatic stalls persist.[6] - CSIS: “The Strait of Hormuz in 8 Charts” (csis.org, published April 22, 2026; data through early June referenced)
Traffic has stayed at a fraction of pre-war levels since the March 2 effective closure (following Feb. 28 strikes). A brief April 17 reopening saw minimal successful transits before reversal. AIS data shows most vessels remain stuck in the Gulf.[7] - WTO Data Lab: Strait of Hormuz Trade Tracker (datalab.wto.org, published May 1, 2026)
LNG shipments hit a near-complete halt (99% drop) since Feb. 28, with zero AIS-traceable passages in key periods. Crude oil saw 95% decline; even brief ceasefires/reopenings yielded no meaningful recovery. Outbound trade in energy remains paralyzed.[8] - Polymarket: “Strait of Hormuz traffic returns to normal by end of June?” (polymarket.com, market active as of June 4, 2026)
Current market implies ~84.5% probability of “No” (traffic not normalizing by June 30), based on Kpler/IMF PortWatch data showing only 5–10 daily transits vs. pre-crisis 100+. Geopolitical tensions and insurance issues sustain the low volumes.[9] - New York Times: “Reopening of Strait of Hormuz Still a Question Mark” (nytimes.com, published May 24, 2026)
A U.S.-Iran “deal in principle” was announced, but details are absent and normal shipping resumption timing is unknown. Oil prices remain elevated amid uncertainty; experts note it could take significant time even with an agreement.[10]
Current Context Summary (as of June 4, 2026):
The Strait remains effectively closed or severely restricted to international LNG traffic due to the ongoing Iran conflict that began February 28, 2026. Iran declared/ enforced closure around March 4; brief April reopening attempts failed quickly. Only sporadic “dark” (AIS-off) passages occur, with no reports of full reopening to all maritime LNG traffic. Negotiations continue but are stalled, with recent Iranian statements reaffirming closure. No major news outlets have reported a full reopening. Historical pre-conflict LNG flows through the strait were ~20% of global seaborne trade (~10.5–11.4 Bcf/d in early 2025 data).[11]
Recent updates (late May–early June 2026) show slight increases in risky dark transits but no normalization. Expert views (shipping firms, analysts) emphasize that sustained peace/insurance clarity is needed for full LNG resumption; Polymarket and data trackers indicate low near-term odds. No authoritative resolution source (e.g., specific port or maritime authority) shows normalized all-traffic LNG flows yet.

Analysis: Strait of Hormuz Reopening to All International Maritime LNG Traffic
Current Situation Assessment (as of June 4, 2026)
The Strait of Hormuz has been effectively closed since late February 2026 following the start of the U.S.-Israeli war with Iran. Key facts:
- Traffic levels: Currently at 5-10% of pre-war levels (~15 vessels daily vs. 100+ pre-war)
- LNG specifically: Near-complete halt (~99% drop according to WTO data)
- Current transits: Only sporadic “dark” (AIS-off) passages with U.S. Navy guidance or IRGC permission
- Ships stranded: ~2,000 commercial vessels, ~20,000 seafarers
- Diplomatic status: Iran recently withdrew from peace talks and reaffirmed intent to “completely block” the strait
- Polymarket: ~84.5% probability that traffic won’t normalize by end of June
Timeline Analysis
Time remaining: ~57 days (approximately 8 weeks)
For resolution to YES, we would need:
- A comprehensive U.S.-Iran peace deal or ceasefire (estimated 3-4 weeks minimum to negotiate)
- Mine clearance operations (experts cite weeks to months)
- Establishment of interim transit systems
- Shipowner/insurer confidence restoration
- Major news outlets reporting the strait is “reopened to ALL international LNG traffic”
Critical Assumptions and Failure Probabilities
Assumption 1: Diplomatic negotiations will remain stalled or progress slowly
- Failure probability: ~15%
- Impact if wrong: Could accelerate timeline significantly, but still leaves operational hurdles
Assumption 2: Even with a deal, operational reopening requires weeks-to-months
- Failure probability: ~10%
- Impact if wrong: Could make July 31 deadline achievable
Assumption 3: The resolution requires truly open traffic, not just increased flows
- Failure probability: ~5%
- Impact if wrong: Current gradual loosening trajectory might eventually suffice
Base Rate Considerations
- Maritime chokepoint closures historically take months to years to fully resolve
- The question requires “ALL international maritime LNG traffic” – a high bar
- Expert analysis (Energy Aspects, Crisis Group) explicitly warns recovery will be “slow, uneven, possibly incomplete”
- Brief April 17 reopening attempt reversed quickly, demonstrating fragility
Probability Calculation
Path 1: Diplomatic breakthrough + rapid implementation
- P(significant breakthrough by ~June 30): ~15%
- P(rapid operational implementation in July | breakthrough): ~25%
- P(major outlets declare “reopened to all LNG” | above): ~50%
- Combined: ~2%
Path 2: Gradual de-escalation reaches threshold
- Given recent Iranian statements and current trajectory
- P(gradual reopening reaches “all traffic” threshold by July 31): ~3%
Path 3: Unexpected events accelerating reopening
- ~3%
Factors Against Resolution
- Recent Iranian withdrawal from talks and closure reaffirmation
- Only 5-10% of normal traffic currently flowing
- Physical constraints (mines, military presence)
- Insurance/risk barriers for LNG carriers (high-value cargo)
- Expert consensus on slow recovery timeline
- Limited time (8 weeks) for all necessary steps
Factors For Resolution
- Some gradual loosening trend observed in late May
- U.S. Navy providing guidance for some transits
- Economic pressure on both sides to resolve
- Unpredictable nature of diplomatic breakthroughs
Adjusting for historical overconfidence and the very high bar set by “all international maritime LNG traffic,” combined with the severely restricted current state and limited remaining time:
Probability: 8%
