The user is asking me to assess whether the Strait of Hormuz will reopen to all international maritime LNG traffic before May 1, 2026.
Today’s date is April 30, 2026, 1:34 PM UTC. That means we’re essentially at the resolution deadline – May 1, 2026 is tomorrow.
Let me analyze what the search results say:
- [1] – Gulf News article: Reports that the LNG tanker Mubaraz became the first loaded vessel to transit the Strait of Hormuz in weeks (dated Tuesday, which appears to be recent – the article seems to be recent based on context). However, it says “tentative thaw” suggesting it’s not fully reopened. Iran has offered to reopen if US lifts blockade.
- [2] – Crypto Briefing: Notes “first LNG shipment exits Strait of Hormuz since 2026 Iran war began” and mentions a “shift from blockade to controlled passage” – suggests some opening but not unrestricted.
- [3] – Oil Price (appears to be April 2026 data): This is very detailed and crucial. It says:
- “Even after repeated announcements by Iran and the USA that Hormuz was ‘open,’ real-time, actual maritime traffic only shows evidence of a near collapse.”
- Vessel traffic is “sometimes as low as three vessels per day, compared to well over 120–140 in normal conditions”
- “Maritime traffic through Hormuz has at times fallen by 90% or more”
- “No reversal of this dynamic has been witnessed even during brief reopenings”
- “In some cases, none of the world’s top shipping companies are willing to take cargo through the Strait”
- Even insurance and shipping lines refuse to transit
- [4] – Discovery Alert: Mentions a Japan-linked tanker crossing but doesn’t provide details about full reopening status.
Key finding: The resolution criteria states ‘Reopened to all international maritime LNG traffic’ means “international maritime LNG traffic through the strait is no longer halted or severely restricted.”
The definition of “severely restricted” is the crux here. With only 3 vessels daily versus the normal 120-140, and major shipping companies actively avoiding the route, the strait remains heavily constrained. The most recent April 2026 data shows no meaningful improvement despite official reopening claims, and with May 1 arriving in hours, the evidence points to the strait not meeting the resolution threshold.
Summary of Key Sources

|---|---|---|---|
| 1 | First LNG tanker crosses Hormuz chokepoint after weeks of disruption | Recent (April 2026) | LNG tanker Mubaraz became first loaded vessel to transit the Strait of Hormuz in weeks, signaling a “tentative thaw” but not unrestricted passage. Iran offered to reopen if US lifts blockade and hostilities end. |
| 2 | First LNG shipment exits Strait of Hormuz since 2026 Iran war began | April 2026 | First LNG shipment to exit since conflict began indicates shift from blockade to “controlled passage,” suggesting selective rather than open traffic. |
| 3 | The Strait of Hormuz May Reopen, But the System Has Already Broken | April 2026 | Despite announcements that Hormuz was “open,” real maritime traffic data shows vessel traffic as low as 3 per day versus normal 120–140. Major shipping companies refuse bookings; insurance remains restrictive. No full reversal of closure dynamics observed. |
| 4 | Japan-Linked Tanker Crosses Strait of Hormuz Amid 2026 Crisis | April 2026 | Confirms some tanker movement but does not indicate full reopening to international maritime traffic. |
Assessment
No, the Strait of Hormuz has not reopened to all international maritime LNG traffic as of April 30, 2026. While isolated LNG vessels have transited the strait in recent weeks, traffic remains severely restricted—disqualifying it under the resolution criteria.
Critical Evidence of Continued Severe Restriction
Vessel traffic collapsed dramatically: According to April 2026 data, maritime traffic through the Strait has fallen to as low as 3 vessels per day, compared to normal conditions of 120–140 vessels daily—representing a 90% or greater reduction.[3] This is definitively “severely restricted” under the resolution criteria.
Major shipping companies refuse transit: Despite announcements of reopening, “in some cases, none of the world’s top shipping companies are willing to take cargo through the Strait.”[3] Insurance markets remain restrictive, and shipping lines are refusing bookings. This systemic refusal by major operators contradicts “all international maritime LNG traffic.”[3]
No reversal of closure dynamics: The most recent April 2026 analysis explicitly states: “No reversal of this dynamic has been witnessed even during brief reopenings. Tankers turn back.”[3] Individual transits of vessels like Mubaraz represent controlled, exceptional passages rather than reopening to unrestricted traffic.
Structural system damage: The war-risk insurance withdrawal in early March “effectively shut down commercial navigation, regardless of whether the Strait was technically open.”[3] Even partial reopenings have not restored confidence or normal operations.
Current Status
The situation represents “controlled passage” rather than reopening—a carefully managed flow of select vessels, not restoration of normal international maritime LNG traffic. With fewer than 24 hours remaining until the May 1 deadline, the trajectory shows no indication of reaching the threshold required by the resolution criteria.

Current Status and Recent Developments
As of April 30, 2026, the Strait of Hormuz remains severely restricted to international maritime traffic, including LNG carriers, due to mutual blockades by Iran and the US amid the ongoing war that began February 28, 2026.[11] Normal daily transits of 125-140 vessels (including ~3 laden LNG tankers) have plummeted to 5-21 sporadically, with ~90-95% reduction; live trackers report 0-3 vessels active and “CLOSED” status.[6][12] This traps ~13 million bpd oil and 300 million cubic meters/day LNG inside the Gulf, primarily Qatar’s exports (42% of some importers’ LNG), forcing shutdowns and reroutes.[13]
Isolated LNG breakthroughs occurred April 27-28: one ADNOC (UAE) tanker crossed outbound to India (first since war), and another reported, but Qatar vessels U-turned amid warnings.[2][3] These are exceptions via Iranian “safe lanes” with permissions, not indicative of unrestricted access; most tankers reverse or anchor outside.[9]
Pattern of Temporary Openings and Reversals
Iran announced “complete openness” April 17 (tied to 10-day ceasefire), prompting brief ~12-20 transits, but revoked April 18 after US blockade refusal, firing on vessels (e.g., Indian ships, tankers).[8][14] Similar April 21 reopening collapsed by April 22; traffic hit post-war highs (77 vessels Mar 30-Apr 5) but fell below 10/day by April 6.[15] No major outlet (Reuters, NYT, BBC, AP) reports sustained reopening to all international LNG traffic—claims are contradicted by data showing “muted,” “trickle,” or “halted.”[1]
Diplomatic Stalemate and Expert Views
Talks via Pakistan/Moscow stalled; Iran proposes reopening tied to US ending blockade/war (April 26-27 offers rejected by Trump).[16] US maintains naval presence, seizing tankers; Iran deploys mines (6-month US clearance estimate).[5] Experts (Brookings, shipping analysts) warn normalization could take weeks-months post-ceasefire due to insurance (20x hike), mine risks, and trust issues; no full LNG resumption expected soon.[5][17]
Impacts and Market Data
Oil (Brent ~$109, WTI ~$105 as of April 30) reflects prolonged disruption; LNG markets repricing higher (UK nat gas 117.6p/therm high).[7] Pre-war: 20% global oil/LNG via strait; now ~70% tanker drop, 150+ anchored outside.[18] With <24 hours to May 1 and no breaking reports of full LNG access from major outlets, criteria unmet; traffic data confirms severe restrictions persist.[19]

Rationale:
This is now almost entirely a “default outcome” question. With less than a day left, the Strait would need to shift from “isolated, exceptional LNG passages” to a condition that major outlets would describe as reopened to all international maritime LNG traffic, meaning no longer halted or severely restricted.
The current evidence points strongly the other way:
- Reuters, NYT, BBC-style reporting describes traffic as muted, sparse, trickling, or still effectively blocked.
- The few LNG transits reported are notable precisely because they are rare exceptions, not normalization.
- Qatar-linked LNG vessels reportedly turned around, which is especially damaging for a “reopened to all LNG traffic” interpretation.
- Structural frictions — mines, war-risk insurance, operator caution, naval blockades, permissions-based safe lanes — make a genuine full reopening much harder than a one-off transit.
The resolution criteria are also fairly demanding. It is not enough that one or two LNG tankers get through, or that Iran says the Strait is “open.” Major news outlets must report that it has reopened to all international maritime LNG traffic, and the fine-grained definition says traffic must no longer be halted or severely restricted. On present evidence, it remains severely restricted.
Time horizon analysis:
- If the question were “in the next 12–24 hours,” I’d put the chance very close to zero but not literally zero because wars can produce sudden diplomatic announcements.
- If the horizon were one week, the odds would still be low but meaningfully higher, because a ceasefire or temporary deal could emerge.
- If the horizon were one month, higher still. But this market is not about one week or one month; it is about the remaining sliver of time before May 1.
Why not exactly 1?
Because there is still a small tail risk of:
- a sudden US-Iran de-escalation deal,
- immediate coordinated insurer/shipping guidance,
- and major outlets treating that as a reopening before the deadline.
But that tail is extremely thin because even a political announcement tonight would likely not instantly erase “severely restricted” conditions in time for reporters to characterize the Strait as reopened to all LNG traffic.
Most important assumptions and their failure risk:
Assumption: The current state remains “severely restricted” through the deadline.
- Failure risk: low.
- Why it matters: if this is wrong, the market could flip quickly.
- My estimate of failure: about 10.
Assumption: One-off or controlled transits will not be interpreted by major outlets as reopening to all LNG traffic.
- Failure risk: modest.
- Why it matters: wording/interpretation risk is one of the only meaningful paths to a surprise Yes.
- My estimate of failure: about 15.
Assumption: No sudden diplomatic breakthrough will occur and be operationalized fast enough before May 1.
- Failure risk: low.
- Why it matters: geopolitics can move abruptly.
- My estimate of failure: about 8.
Putting it together, the base case is overwhelmingly No, and with such little time left I should lean hard against last-minute trend extrapolation. My calibrated estimate is very low, but not negligible.

Timeline Assessment: Today is April 30, 2026, and the resolution deadline is May 1, 2026—leaving fewer than 24 hours for the Strait of Hormuz to reopen to all international maritime LNG traffic.
Current Status (as of April 30):
- Live trackers report the strait as CLOSED to commercial traffic
- Daily vessel transits: 3-21 vessels vs. normal 120-140 (90-95% reduction)
- Only one laden LNG tanker (ADNOC) has crossed since the war began on Feb 28
- Qatar LNG carriers—the dominant Gulf LNG exporters—are actively turning back
- Major shipping companies refuse bookings through the strait
Structural Barriers to Reopening Within Hours:
- Mines: Iran has deployed mines; US estimates 6 months to clear them
- Insurance: War-risk premiums surged 20x, effectively blocking commercial navigation regardless of physical access
- Diplomatic stalemate: Iran’s April 26-27 reopening proposals were rejected by Trump; no new talks reported
- Pattern of failed openings: April 17 and April 21 “reopenings” each collapsed within 24-48 hours
Critical Assumptions to Test:
| Assumption | Probability of Failure | Impact |
|---|---|---|
| No surprise ceasefire/deal in next hours | ~2% chance of surprise deal | Even if deal announced, physical/insurance barriers prevent immediate “all traffic” resumption |
| Resolution requires “all international maritime LNG traffic” not just isolated transits | Very high confidence in this reading | Even one ADNOC tanker crossing doesn’t meet threshold |
| Live tracker “CLOSED” status is accurate | ~1% chance of error | All major outlets (Reuters, NYT, BBC, CNN) corroborate severe restrictions |
Even in the most optimistic scenario—a surprise ceasefire announced tonight—experts estimate weeks to months before normal LNG traffic could resume due to mine clearance, insurance normalization, and rebuilding shipping confidence. The resolution criteria demands traffic be “no longer halted or severely restricted,” which cannot physically occur in hours.
Base rate consideration: Of the multiple attempted reopenings (April 17, 21), none lasted more than 48 hours, and none achieved anything close to normal LNG traffic levels. The structural conditions have not changed since those failures.

Reasoning
Current Status (April 30, 2026):
The Strait of Hormuz is effectively CLOSED to commercial LNG traffic. Live trackers confirm this status as of today. The ongoing Iran war (started February 28, 2026) has created mutual blockades by Iran and the US.
Key Evidence Against Resolution:
- Traffic collapse: Only 3-21 vessels per day vs. normal 120-140 (~90-95% reduction). Only ONE laden LNG tanker (ADNOC) has crossed since the war began, on April 27-28.
- Qatar LNG vessels actively turning back: Qatar carriers made U-turns amid warnings as recently as April 29.
- Live tracker status: “CLOSED” as of April 30, 2026.
- Diplomatic deadlock: Trump rejected Iran’s reopening proposal on April 26-27. No new talks scheduled.
- Physical impediments: Iranian mines require estimated 6 months to clear per US military assessment.
- Insurance/commercial barriers: War-risk insurance surged 20x; major shipping companies refuse bookings.
- Pattern of false openings: Every brief reopening (April 17, April 21) collapsed within 24 hours.
What would need to happen in <24 hours:
- Full ceasefire agreement
- Mine clearance (physically impossible in hours)
- Insurance markets normalize (takes weeks minimum)
- Major shipping companies resume bookings
- Major news outlets report unrestricted LNG traffic
Critical assumptions that could change this:
| Assumption | Probability of Failure | Impact |
|---|---|---|
| No surprise ceasefire deal in next 18 hours | ~2% chance of surprise deal, but even a deal wouldn’t restore “all” LNG traffic immediately | Low impact even if wrong – physical/insurance barriers remain |
| Physical mine threat prevents normalization | <1% chance mines are cleared overnight | High impact if wrong, but physically impossible |
| Insurance markets can’t normalize in hours | <0.5% | High impact but institutionally impossible |
Even in the most optimistic scenario where a surprise ceasefire is announced tonight, the resolution requires traffic to be “no longer halted or severely restricted.” Physical mine risks, insurance costs, and shipping company policies cannot normalize in hours. The ADNOC tanker crossing was explicitly described as an exception, not a reopening.
Timeline analysis:
- By May 1 (tomorrow): ~1%
- By June 1: ~5%
- By September 1: ~15-25%
- By end of 2026: ~30-40%
The probability is essentially negligible given the less-than-24-hour window and the massive structural barriers to full reopening.

Current Status (April 30, 2026):
The Strait of Hormuz is currently CLOSED to commercial traffic per live tracking data, with vessel traffic 90-95% below normal levels (3-21 vessels/day vs. 120-140 normal). The live monitor shows “CLOSED” status as of today.
LNG-Specific Evidence:
- Only one laden LNG tanker (ADNOC) has transited since the war began February 28 — on April 27-28
- Qatar LNG carriers U-turned amid warnings as recently as April 29
- Normal LNG traffic was ~3 laden tankers/day; current rate is essentially zero sustained flow
- No major outlet (Reuters, NYT, BBC, AP) reports reopening to “all” international LNG traffic
Structural Barriers to Immediate Reopening:
- Iranian mines require estimated 6 months to clear (US assessment)
- War-risk insurance costs surged 20x, effectively blocking commercial navigation
- Major shipping companies refuse to book cargo through the strait
- Pattern of brief openings (April 17, April 21) collapsed within hours
Diplomatic Situation:
- Talks stalled; Iran’s April 26-27 proposals rejected by Trump
- No breakthrough negotiations reported in the last 48 hours
- Mutual US-Iran blockades persist
Time Remaining: Less than 24 hours until May 1, 2026.
Critical Assumptions and Failure Probabilities:
| Assumption | Failure Probability | Impact |
|---|---|---|
| No surprise peace deal in next ~12 hours | ~1-2% chance of surprise deal | Even if deal announced, wouldn’t restore “all” traffic instantly |
| Physical/structural barriers prevent instant normalization | ~0.1% these could be overcome in hours | Mines, insurance, shipping company reluctance |
| Resolution requires “all international maritime LNG traffic” not just isolated transits | N/A – clear from criteria | Current single-tanker transits definitively don’t qualify |
Even in the extraordinarily unlikely scenario of a surprise peace announcement tonight, the resolution requires traffic to be “no longer halted or severely restricted” — which is physically impossible given mines, insurance barriers, and shipping company reluctance. The combined probability of all necessary conditions being met in <24 hours is vanishingly small.

GPT Binary response:
The decisive factor here is not whether some LNG tankers can transit, but whether the strait is reported by major outlets as reopened to all international maritime LNG traffic, meaning traffic is no longer halted or severely restricted.
Right now, the best and most recent reporting points the other way:
- Reuters, NYT, BBC, and others describe only isolated LNG transits, not normalization.
- Reuters reporting from April 27-29 says traffic remains muted, with the first loaded LNG transit since the war being notable precisely because it was exceptional.
- Other reporting says Qatar LNG vessels have turned back, traffic remains far below normal, and the strait is still under effective blockade / controlled passage conditions.
- Even where Iran has claimed the strait was “open,” shipping data and subsequent reporting indicate that commercial traffic remained sparse and highly constrained.
- Structural frictions like mines, war-risk insurance, operator reluctance, and dual blockade behavior make “reopened to all international maritime LNG traffic” much harder than a single diplomatic announcement.
Time matters enormously here. We are on April 30 with less than a day left. For this to resolve Yes, several things would need to happen almost immediately:
- a real and credible political/security breakthrough,
- enough practical change that LNG traffic is no longer “halted or severely restricted,” and
- major news outlets actually characterize the situation as reopened to all international maritime LNG traffic before May 1.
That is a very high bar in a very short window.
A useful way to frame it:
- If the question were “within 1 week,” I’d still only put the odds in the high single digits.
- “Within 1 month” might be materially higher, but still limited by mines, insurance, and trust.
- “Before May 1” compresses the probability dramatically.
Key assumptions that could be wrong and would most move the forecast:
- Assumption: Major outlets will not treat isolated or permission-based transits as “reopened to all LNG traffic.”
Chance this assumption is wrong: about 7%.
If wrong, the Yes probability rises some, but not massively because most current reporting is explicit that restrictions remain severe. - Assumption: No sudden diplomatic breakthrough occurs in the remaining hours.
Chance this assumption is wrong: about 4%.
Even if wrong, practical implementation before the deadline is still difficult. - Assumption: Operational constraints (insurance, mines, operator reluctance, military risk) prevent any immediate shift from “controlled passage” to “no longer severely restricted.”
Chance this assumption is wrong: about 8%.
This is the assumption that matters most substantively, and current reporting supports it strongly.
My base case is overwhelmingly that the strait does not meet the resolution standard before the deadline. I leave a sliver for a late-breaking news reclassification or an abrupt diplomatic move, but only a sliver.

An analysis of the current situation in the Strait of Hormuz indicates that the conditions for a “Yes” resolution are extraordinarily unlikely to be met before the May 1, 2026 deadline. The forecast is based on the severe discrepancy between the resolution criteria and the facts on the ground, compounded by an extremely short timeframe.
Reasoning for the Forecast
- Current State is “Severely Restricted”: The resolution criteria’s core condition is that LNG traffic must no longer be “halted or severely restricted.” As of April 30, 2026, all available evidence points to traffic being severely restricted. Multiple sources confirm that vessel traffic has plummeted by 90-95% from its pre-war normal of 120-140 vessels per day. Real-time trackers have even reported the strait as “CLOSED” to commercial traffic. While there has been an isolated transit of a single loaded LNG tanker, an event so rare it was newsworthy, it stands in stark contrast to the pre-war average of three per day and does not constitute a reopening. Critically, LNG vessels from Qatar, a primary exporter, have recently been observed reversing course, demonstrating that consistent access is not available.
- Insurmountable Time Constraint: The question resolves in less than 24 hours. For a “Yes” resolution, not only would a complete diplomatic and military reversal have to occur, but major news outlets would also need to verify and report that traffic is no longer severely restricted. Given the current stalemate in negotiations and the entrenched military positions, a sudden breakthrough is highly improbable.
- Structural Barriers to Reopening: Even in the highly unlikely event of an immediate ceasefire agreement today, the operational reality on the water would not change instantly.
- Insurance and Risk: Major shipping and insurance companies have deemed the strait too high-risk, a policy that would not be reversed in mere hours. Confidence would need to be rebuilt over days or weeks, not moments.
- Physical Dangers: The US military estimates a six-month timeline would be required to clear the strait of Iranian mines after hostilities cease. This physical danger would keep traffic severely restricted regardless of any political declarations.
- Assumptions and Confidence:
- Assumption 1: The provided high-quality intelligence from sources like Reuters, NYT, BBC, and data firms like Kpler is accurate. The probability of this assumption being incorrect is extremely low (<1%), as the sources are numerous and corroborating.
- Assumption 2: A “black swan” diplomatic event will not materialize and be fully implemented in the next 18 hours. The probability of this assumption failing is exceptionally low. Even if a deal were announced, the resolution criteria hinge on the de facto state of traffic (“no longer severely restricted”), which would lag far behind any political announcement.
Given these factors, the path to a “Yes” resolution is virtually non-existent. The current state is the polar opposite of the resolution criteria, and there is no time for this to change.
Probability: 1%
The extracted probability is: 1%
GPT Binary response:
The base case is overwhelmingly No.
Why:
- The resolution bar is not “some LNG got through.” It is “reopened to all international maritime LNG traffic,” defined as no longer halted or severely restricted.
- The freshest reporting says the opposite: isolated LNG passages, Qatar LNG vessels still turning back, overall traffic still a fraction of normal, and major outlets describing the strait as “muted,” “largely closed,” or only under “controlled passage.”
- We are now at April 30 with less than a day left. For this to resolve Yes, there would need to be a very rapid, clearly reportable regime change that major outlets characterize as a reopening to all international LNG traffic, not just another temporary or selective easing.
- Even if a last-minute diplomatic breakthrough occurred, there is a second hurdle: journalists would need enough evidence to say the strait is no longer severely restricted. Given mines, insurance constraints, naval blockades, and the pattern of brief openings followed by reversals, that is hard to establish within hours.
A useful decomposition:
- Chance of a major diplomatic/military breakthrough in the remaining window: low.
- Chance that such a breakthrough actually changes conditions for LNG traffic immediately, rather than in principle: lower.
- Chance major news outlets describe that change as reopened to all international maritime LNG traffic before the deadline: lower still.
So while a single surprise headline is always possible, the combination required for a Yes is extremely demanding.
Short-horizon calibration:
- Before May 1: very low.
- Within a week: still low, but meaningfully higher than before May 1.
- Within a month: higher again, though still far from certain because insurance, clearance, and trust restoration lag any ceasefire.
Key assumptions that could most change this forecast:
- Current reporting is accurately describing the strait as still severely restricted.
Chance this is materially wrong or overtaken in the next hours: about 8%. - The market will interpret “reopened to all international maritime LNG traffic” strictly, not count a few escorted or permitted LNG sailings as sufficient.
Chance this assumption is wrong: about 10%. - No sudden late-breaking agreement is reached and reported fast enough to satisfy the criteria.
Chance this assumption is wrong: about 6%.
Those failure probabilities are not additive, and even if one fails, resolution is not automatic. After accounting for overlap and the very short remaining time, the positive resolution probability still lands near the floor.

- Current State is “Severely Restricted”: The resolution criteria’s core condition is that LNG traffic must no longer be “halted or severely restricted.” As of April 30, 2026, all available evidence points to traffic being severely restricted. Multiple sources confirm that vessel traffic has plummeted by 90-95% from its pre-war normal of 120-140 vessels per day. Real-time trackers have even reported the strait as “CLOSED” to commercial traffic. While there has been an isolated transit of a single loaded LNG tanker, an event so rare it was newsworthy, it stands in stark contrast to the pre-war average of three per day and does not constitute a reopening. Critically, LNG vessels from Qatar, a primary exporter, have recently been observed reversing course, demonstrating that consistent access is not available.
- Insurmountable Time Constraint: The question resolves in less than 24 hours. For a “Yes” resolution, not only would a complete diplomatic and military reversal have to occur, but major news outlets would also need to verify and report that traffic is no longer severely restricted. Given the current stalemate in negotiations and the entrenched military positions, a sudden breakthrough is highly improbable.
- Structural Barriers to Reopening: Even in the highly unlikely event of an immediate ceasefire agreement today, the operational reality on the water would not change instantly.
- Insurance and Risk: Major shipping and insurance companies have deemed the strait too high-risk, a policy that would not be reversed in mere hours. Confidence would need to be rebuilt over days or weeks, not moments.
- Physical Dangers: The US military estimates a six-month timeline would be required to clear the strait of Iranian mines after hostilities cease. This physical danger would keep traffic severely restricted regardless of any political declarations.
- Assumptions and Confidence:
- Assumption 1: The provided high-quality intelligence from sources like Reuters, NYT, BBC, and data firms like Kpler is accurate. The probability of this assumption being incorrect is extremely low (<1%), as the sources are numerous and corroborating.
- Assumption 2: A “black swan” diplomatic event will not materialize and be fully implemented in the next 18 hours. The probability of this assumption failing is exceptionally low. Even if a deal were announced, the resolution criteria hinge on the de facto state of traffic (“no longer severely restricted”), which would lag far behind any political announcement.
Given these factors, the path to a “Yes” resolution is virtually non-existent. The current state is the polar opposite of the resolution criteria, and there is no time for this to change.
Probability: 1%
