Phil: Will the Strait of Hormuz reopen to all LNG traffic before May 2026?

This is its condensed report. Full version here.

Perplexity response:

{think}
Let me analyze this question carefully. The user is asking whether the Strait of Hormuz will reopen to all international maritime LNG traffic before May 1, 2026.

Current date: April 23, 2026, 1:32:45 PM UTC
Resolution date: May 1, 2026
Time remaining: ~8 days

Pattern Observed: The past week demonstrates rapid reversals between announced openings and actual closures. Iran’s foreign minister announced passage was “fully open” on April 17[1], yet by April 20-21, international maritime traffic had been reduced to Iran-linked vessels only, representing a return to severe restriction rather than genuine reopening.

Time Constraint: With 8 days remaining until May 1, 2026, a sustained reopening would require immediate stabilization and reversal of the current restrictive trajectory.

Published: April 14, 2026
Summary: Traffic drops post-US blockade; first non-Iranian LPG since March but LNG halted. Ships avoid due to mines/warnings. Data shows persistent low volumes into late April.[10]

The Strait of Hormuz, vital for ~20% of global LNG (primarily Qatari exports to Asia/Europe), has been severely restricted since Iran closed it on February 28, 2026, at the war’s outset, with traffic dropping to near zero initially.[3][11] Brief exceptions allowed select non-Western ships (e.g., Chinese, Indian LPG in March), but no unrestricted international LNG transits occurred, and attacks/mines deterred most.[3] A ceasefire around April 8 led to Iran’s April 17 “full opening” announcement, enabling ~12-20 ships briefly, but it was revoked April 18 after US blockade refusal, with shots fired and U-turns by LNG tankers.[4][2]

As of April 23, traffic remains halted: 5 ships/24h (vs. normal 60-140), no LNG transits reported in trackers; 280+ vessels stranded (85 tankers), war risk insurance at 1% premiums (6.7x normal).[1][4] Recent seizures (Iran: 11 ships, US/UK:4) and attacks (e.g., April 22-23 videos of IRGC actions) confirm severe restrictions; UKMTO rates risk “critical” with navigation interference/mines.[12] No major outlet (Reuters, NYT, Bloomberg) reports full reopening to all international LNG; Iran blames US “breaches,” stating impossible now.[6]

Shipping experts (BRS, Kpler) note tankers trapped with millions of barrels; UN/IMO urge caution for 20,000 seafarers; execs tell CNBC no plans to risk LNG runs amid uncertainty.[4][13] Prediction markets (Polymarket) price ~12-28% for April 30 normalization, dropping post-reimposition; EIA forecasts prolonged shut-ins (9.1M b/d oil equivalent impacts).[8][14] Recent updates (April 21-23) show no movement toward unrestricted LNG; volatility high with failed talks, mine-clearing (6 months Pentagon est.), toll demands.[15]

=== Forecast Result ===

=== Reasoning ===
This is a binary outcome question with a very short timeline. My analysis must focus on the immediate barriers to reopening and the likelihood of those barriers being removed in the next seven days.

Reasoning Rationale

Current Status is Far from Resolution: As of April 23, 2026, the Strait of Hormuz is “severely restricted.” Traffic is approximately 5-10% of its normal volume, with reports indicating that no international LNG carriers are transiting. Recent updates confirm continued military activity, including ship seizures and attacks, with the UK’s maritime authority rating the risk as “critical.” The current situation is the opposite of the resolution criteria, which requires the strait to be “no longer halted or severely restricted” for “all international maritime LNG traffic.”
Extremely Short Timeline: The resolution deadline is May 1, 2026, leaving only seven full days for a complete reversal of the current military and political situation. Such a rapid de-escalation during an active war is highly improbable. The base rate for resolving major geopolitical conflicts and restoring full commercial operations in a contested strait within one week is exceedingly low.
Failed Reopening and Lack of Trust: A critical event was the failed reopening attempt around April 17-18. Iran announced a “full opening,” but this was revoked within 24-48 hours amid reports of gunfire and a refusal by the US to lift its blockade. This “head fake” has destroyed trust. Even if a new political agreement were announced, shipping companies and their insurers would likely wait for a period of demonstrated, sustained safety before resuming transit, a process that would almost certainly take longer than the seven days remaining.
Hardening Political Stances: The primary driver of the closure is the ongoing war. Recent diplomatic signals are negative. An Iranian negotiator was quoted on April 23 stating that a reopening is “not possible” due to alleged US ceasefire breaches. This indicates that the political will for a swift reopening is absent and that the strait is being used as a point of leverage in the conflict.
Logistical and Physical Barriers: Beyond any political agreement, significant logistical hurdles remain. These include the high cost of war risk insurance (reportedly 6.7 times normal levels), the physical danger from potential naval mines (which the Pentagon estimated could take six months to clear), and active interference with vessel navigation. It is implausible that these risks could be neutralized and certified as safe for all traffic, particularly high-value LNG carriers, before May 1.

Key Assumptions & Probabilities of Failure:

Assumption 1: There will be no sudden, durable ceasefire and security agreement between Iran and the US/allies that is implemented in the next seven days.
- Probability of this assumption being incorrect: Very low, estimated at <5%. The current trajectory is one of continued conflict, not imminent resolution.
Assumption 2: Even if a political deal were announced, shipping and insurance companies would not immediately resume full LNG traffic due to the “trust deficit” from the April 18 reversal and ongoing physical risks.
- Probability of this assumption being incorrect: Extremely low, estimated at <2%. Standard risk management practices would prevent an immediate return to normal operations in a volatile war zone.

Conclusion:

Given the active conflict, the failed reopening attempt, the hardening political rhetoric, and the significant logistical barriers, the probability of the Strait of Hormuz reopening to all international LNG traffic in a “not severely restricted” manner within the next seven days is extremely low. The event would require an extraordinary and improbable sequence of positive political, military, and commercial developments.
