Strait of Hormuz Maritime Disruption: Seafarer Stranding and Strategic Chokepoint Vulnerability

Executive Summary

Tankers and cargo ships have been stuck in the Persian Gulf since the US and Israel attacked Iran on February 28, collapsing tanker traffic through a strait that previously carried about 20 percent of global oil supplies and triggering what the IEA characterized as the largest supply disruption in the history of the global oil market.

Around 11,000 seafarers are now being evacuated in a large-scale IMO operation launched after a peace agreement between the United States and Iran, a deal that Dominguez welcomed as "a decisive step towards restoring maritime security."

Volatility surrounding the waterway persists, however: Tehran announced a fresh closure following renewed clashes between Israel and Hezbollah in Lebanon, and uncertainty regarding the future management of the strategic channel remains prevalent even as maritime traffic shows early signs of recovery. For corporate strategists and risk managers, the episode is not an aberration but a stress test of a known structural fragility, one that international governance frameworks, market insurance systems, and energy supply chains all failed to adequately hedge.

The Chokepoint Problem International Frameworks Failed To Solve

The Strait of Hormuz, through which an average of 20 million barrels per day of crude oil and oil products were shipped in 2025, is one of the world's most critical oil transit chokepoints; with around 25 percent of the world's seaborne oil trade transiting the Strait and options to bypass it being limited, any disruption to flows would have substantial consequences for world oil markets. That assessment has appeared in IEA documentation for years. The gap this crisis exposed is not one of knowledge, every energy security planner knew the strait was the world's most critical chokepoint, but of governance readiness for the scenario where a state actor with physical control over the strait chooses to exercise that control.

Only Saudi Arabia and the UAE have operational crude pipelines that could potentially re-route flows to bypass the Strait, with an estimated 3.5 to 5.5 million barrels per day of available capacity; the logistics and supply chains needed to re-route and export substantial flows have not been robustly tested. The IEA's Strait of Hormuz contingency documentation, which identified this bypass constraint before the conflict, was accurate in diagnosis but insufficient in prescribing an operational response. Saudi Arabia and the UAE successfully redirected some exports to terminals loading outside the Strait, while producers outside the Middle East pushed output higher and lifted exports to record levels in response to the crisis. These partial mitigations bought time but could not substitute for the volume of the closure, cumulative supply losses from Gulf producers already exceeded one billion barrels with more than 14 million barrels per day of oil shut in, a significant supply shock.

The interplay between physical bypass constraints and geopolitical coercion reveals a structural asymmetry that analysts had consistently underweighted: the effort required to close the strait is vastly smaller than the effort required to replace its throughput. Iran's ability to mine the waterway, achievable in hours or days, imposed costs on the global economy that will take months or years to fully unwind. At the conservative confirmed threshold, the 2026 closure represents a supply withdrawal roughly two to three times larger than any previous oil shock on record, meaning the historical models that policymakers, traders, and analysts have relied upon to forecast resolution timelines are only partially applicable.

Both the economic and operational dimensions of this failure demand attention from any organization that depends on Gulf energy supply or Gulf transit routing. For Kuwait, the disruption exposed a near-total dependence on a single maritime passage for the export of a resource that generates the overwhelming majority of the country's national revenue , a dynamic that applies with varying intensity to Iraq, Qatar, Bahrain, and portions of Saudi and UAE exports as well.

How Seafarer Stranding Became A Geopolitical Lever

The humanitarian dimension of the closure, 14 deaths and months of psychological distress for more than 11,000 seafarers, did not produce immediate international intervention. The IMO's hot topics page noted it was closely monitoring developments to protect more than 20,000 seafarers in the region, including those stranded on vessels unable to exit the Strait of Hormuz , a figure that encompasses port workers and offshore crews beyond the stranded vessel population. Despite this visibility, the IMO lacked the authority to compel safe passage from a belligerent state.

Tehran subsequently announced a fresh closure of the strait following renewed clashes between Israel and the Iran-backed Hezbollah movement in Lebanon even after an initial accord was reached; diplomatic engagements between Washington and Tehran proceeded following talks in Switzerland that initiated a 60-day window focused on achieving a permanent resolution. The sequential pattern, ceasefire, breakdown, renewed negotiations, illustrates why the seafarers remained stranded for months even after the political intent to resolve the crisis was expressed. The operational pathway to resolution proved far more complex than the diplomatic pathway.

Jacob Shapiro of the Bespoke Group, speaking at Marine Money in New York in June 2026 and covered by Seatrade Maritime News, framed this within a structural shift toward competing supply chains driven by great-power competition. On this reading, civilian seafarers absorbed costs that neither belligerent bears directly, a form of externalization that existing maritime law does not adequately prevent. The UN News coverage in March 2026 noted the absence of a post-World War II precedent for the scale of seafarer exposure in a conflict zone, and the IMO Council's resolution of May 22, requesting support for evacuation of ships and seafarers trapped in the Persian Gulf, illustrates how long it took international bodies to move from monitoring to action.

This dynamic spills into the labor market dimension of maritime risk. Shipping companies and crewing agencies that place seafarers on Gulf-transiting vessels now face new duty-of-care obligations that existing contracts were not designed to address. Hapag-Lloyd's Managing Director of Fleet, Silke Lehmköster, noted at the SMM 2026 conference in June that resilience has become a key competitive factor for global supply chains, a formulation that implicitly acknowledges seafarer welfare as part of operational resilience calculus, not merely a humanitarian afterthought.

The Commodity Cascade Beyond Oil

The IEA's June 2026 energy crisis page stated its Executive Director described the combined impacts as "the greatest threat to global energy security in history." Regional gas production was also affected by the shutting in of oil fields, reducing the output of associated gas; natural gas prices in Asian markets rose sharply as buyers competed for a smaller pool of LNG cargoes; and higher prices and supply constraints prompted demand-side adjustments including gas rationing in some countries.

The fertilizer dimension has received less analytical attention but carries comparable downstream severity. Wikipedia's 2026 Iran war fuel crisis article documented that the crisis caused severe disruption to the distribution of urea used for fertilizer alongside petroleum products and LNG, with much of the world affected by disruption to those commodity flows. Fertilizer supply disruptions translate into higher agricultural input costs with a 6-18 month lag before they reach retail food prices, meaning the food-security transmission of the Hormuz closure is moderate-to-high confidence not yet fully visible in price data as of late June 2026. The FAO's response tracker, cited on the IMO's Middle East hot topics page, was already monitoring global agrifood implications of the conflict as of March 2026.

Global oil demand contracted by 2.4 million barrels per day year-on-year in the second quarter of 2026, with the steepest losses in the petrochemical sector where feedstock availability became increasingly constrained; aviation activity ran well below normal levels; and jet fuel prices rose sharply after Middle Eastern exports were cut off. These demand-side contractions represent a second-order economic effect: the supply disruption created its own demand destruction, which in turn slowed the economic engines, particularly in Asia, that drive long-term energy demand. The broader systemic implications include a compression of corporate revenue, tax receipts, and fiscal headroom in import-dependent economies precisely when those governments faced the highest energy subsidy burden.

The Post-Conflict Transit Regime Taking Shape

Iran's Ambassador Ali Bahreini announced on June 23 that the Strait of Hormuz is fully open to commercial vessels without tolls. That statement closes one uncertainty, whether tolls would be imposed immediately, while opening another: the announcement's framing as a 60-day arrangement, reflected in community commentary, implies that the post-moratorium regime has not been settled. Secretary Rubio's statement in the UAE, that no country is allowed to charge tolls on an international waterway under existing international law, was a proactive legal claim made in anticipation of potential future Iranian action, not a response to an already-resolved dispute.

GPS interference, which grew notably more intense as US-Iranian tensions peaked, has also subsided in recent days, but the IMO noted it would issue daily reports on the number of ships leaving the region safely, a monitoring cadence that signals the corridor remains fragile rather than normalized. The shipping industry is confronting a new challenge to restoring the critical trade route: for months, ships waiting to cross the strait have accumulated substantial amounts of debris on their hulls, which now needs to be removed , a mundane but real operational bottleneck that will slow the pace of vessel departure regardless of diplomatic progress.

The Maritime Executive's analysis in June 2026 noted that the IRGC's drone and missile sites were built in expectation of attack, well dispersed, and that the speed of some site repairs suggested pre-positioned recovery resources. The broader systemic implication is that Iran's coercive capability, the capability that enabled the closure, has not been permanently degraded. This asymmetry between diplomatic normalization and capability reconstitution is the central unresolved variable for long-term Hormuz risk assessment. Taken together, the mine clearance timeline, the 60-day toll moratorium, and the IRGC capability question define a risk environment that warrants sustained monitoring well into 2027.

Counterarguments

1. The rapid post-agreement response challenges the "governance failure" framing, the system may have worked within its design limits. One substantive critique is that the IMO was never designed to operate as a belligerent-negotiation agency. The organization's rapid deployment of an evacuation plan within eight days of the June 15 MOU suggests it was ready and waiting for the political green light. Framing the four-month delay as a governance failure may misattribute the constraint: the bottleneck was diplomatic, not institutional. The stronger version of this argument holds that demanding the IMO negotiate with belligerents would require a legal rewrite of the organization's mandate, a precedent that could be exploited to pressure the IMO into political roles it is structurally unfit to perform. The countercase is real: if the IMO cannot act until belligerents sign an MOU, and if MOU negotiations take four months, then 14 people died in a gap that institutional design perpetuates.

2. The commodity cascade severity assessment may be overstated if demand destruction acted as a partial self-correction. The IEA reported in its May Oil Market Report that global oil demand was projected to decline by 420,000 barrels per day for 2026 as a whole, a significant contraction that implies the supply shock was partly offset by reduced consumption. Global oil demand was expected to contract by 2.4 million barrels per day year-on-year in the second quarter of 2026. If demand destruction is large enough and fast enough, the inventory draw rate slows and the physical shortage becomes less acute than the headline supply loss implies. An analyst who concludes the cascade is still propagating into 2027 should stress-test whether demand-side adjustment has already absorbed a larger share of the shock than the supply-side framing suggests.

3. The precedent value of the IMO-Oman evacuation corridor may be lower than assessed because its conditions were unique. The corridor was made possible by the convergence of Iranian financial desperation, US diplomatic pressure in the Gulf, and Oman's established role as a trusted intermediary, a specific conjunction of factors low confidence to replicate in future chokepoint crises involving different actors. If the next closure occurs in the Malacca Strait, the Bab el-Mandeb, or the Turkish Straits, the intermediary architecture that made the Hormuz corridor possible does not automatically transfer. Risk managers who draw comfort from the June 2026 response as evidence that the international community can manage chokepoint crises should be cautious about generalizing from a case with unusually favorable enabling conditions.

Indicators To Watch

Decision Relevance

Scenario A (~50%): Phased normalization with 60-day toll moratorium expiring into diplomatic ambiguity, Mine clearance proceeds within IEA's 6-8 month base case, oil flow recovery reaches 60-70 percent of pre-conflict levels by Q4 2026, but the post-moratorium toll question remains unresolved and IRGC capability reconstitution proceeds quietly. Recommended action: energy importers should maintain diversified crude procurement with non-Hormuz alternatives at contract-ready status and not assume pre-conflict insurance premium levels in 2027 renewals; shipping operators should build mine-clearance delay buffers into voyage scheduling; corporate strategists should model a $10-20/bbl structural risk premium on Gulf-origin crude through mid-2027 and avoid locking in long-term energy contracts priced on a full normalization assumption.

Scenario B (~35%): Delayed normalization driven by IRGC capability reconstitution or Houthi activation, Physical recovery in the strait proceeds slower than the IEA base case due to mine density, renewed pressure from IRGC factions, or Houthi decision to activate Red Sea leverage. The IEA's cumulative 900-million-barrel inventory deficit cited in the May report is not replenished on schedule. Recommended action: energy-intensive manufacturers and power generators dependent on Gulf LNG or crude should initiate strategic reserve drawdown contingency protocols now; port operators and logistics planners in Asia should accelerate contracts for non-Hormuz-dependent supply routes including West African crude and Atlantic Basin LNG; asset managers with energy sector exposure should maintain overweight positions in non-Gulf producers and hedge LNG price exposure through 2027.

Scenario C (~15%): Accelerated normalization with Iran accepting full free transit under sanctions-relief conditionality, Iran's fiscal emergency, Seatrade Maritime News reported an over-90-percent collapse in oil exports during the blockade, produces a negotiated settlement that trades full transit normalization for meaningful sanctions relief, removing the toll ambiguity and accelerating mine clearance under international supervision. Recommended action: energy traders should prepare for a supply-overhang correction as stranded cargoes simultaneously reach markets; tanker operators can begin repricing Gulf transit rates toward pre-conflict benchmarks; strategic reserve re-stocking programs would accelerate, temporarily supporting VLCC demand; corporate energy buyers should consider opportunistic contract renegotiation during the normalization window before the market reprices to reflect rebuilt inventory.

Analytical Limitations

• The physical density and extent of Iranian mine deployment in the strait is not publicly documented. Mine clearance timelines are derived from IEA modeling, Omani official statements, and Rubio's June 2 congressional testimony, not direct hydrographic survey data available in open sources. If mine density is materially higher than implied by current reporting, all transit normalization and supply recovery timelines require downward revision.

• Iran's post-60-day toll intentions are not observable from current open sources. The June 23 ambassador statement is a formal denial, but its temporary framing and the Maritime Executive's independent assessment of permanent regime change signal genuine ambiguity. The toll assessment is provisional and the picture remains mixed.

• The full demand-side economic impact of the four-month closure on GDP, industrial output, and food security in Asian import-dependent economies will not be visible in published data until late Q3 or Q4 2026 at the earliest, given statistical reporting lags. The food-security transmission through fertilizer supply disruption is subject to a further 6-18 month lag.

• Renewed hostilities risk is present but opaque. The ANI News report that Tehran announced a fresh closure following Israeli-Hezbollah clashes signals that the MOU's durability is event-dependent, not self-executing. The conditions under which Iran would re-close, and how quickly the IMO corridor could be reinstated, are not documented in available sources.

Securitization Theory Analysis

Securitizing Actor: The primary securitizing actors were the United States and Israel, whose joint air strikes on Iran beginning February 28 initiated the conflict, and Iran, which securitized the Strait of Hormuz itself as a legitimate sovereign response mechanism. The IMO and the UN acted as secondary securitizing actors, framing the seafarer crisis as a global humanitarian emergency requiring exceptional multilateral action beyond normal maritime governance. The FAO's parallel framing of global agrifood implications extended the securitization into food-security domains.

Referent Object: Multiple referent objects operated simultaneously. Iran framed its nuclear program and regime survival as the existential objects under threat, justifying extraordinary measures. The United States and allied shipping nations framed freedom of navigation as a foundational norm whose violation threatened the international rules-based order. The IMO and seafarer unions framed civilian maritime workers as a protected class under international humanitarian principles. The IMO's own framing acknowledged that around 20,000 seafarers, port workers, and offshore crews were impacted, while stating that IMO's primary concern remained the humanitarian and safety implications for seafarers.

Existential Threat Construction: Iran's closure of the strait was framed domestically as a proportional response to existential military attack, deploying the "international waterway" as a lever precisely because its use imposed globally distributed costs that no single actor could absorb unilaterally. IMO Secretary-General Dominguez's language, "unacceptable attacks against civilian shipping" and "months of hardship and distress", was calibrated to invoke humanitarian emergency norms and build the political audience for an evacuation framework. Rubio's invocation of UNCLOS in the UAE on June 23 was simultaneously a legal claim and a securitizing speech act constructing toll-charging as a violation of international order rather than merely a commercial dispute.

Target Audience: Iran's securitization was directed at domestic constituencies and regional states capable of providing sanctions relief or diplomatic recognition. US securitization targeted Gulf allies and energy-dependent Asian states whose support was needed to maintain the coalition pressure that produced the MOU. The IMO's framing targeted all member states and the shipping industry, seeking to mobilize the political will to act for seafarer welfare in the absence of coercive authority.

Extraordinary Measures: The extraordinary measures already in motion include the multinational evacuation corridor with no peacetime precedent; the IEA's coordinated emergency stock release of 400 million barrels agreed March 11 by all 32 member countries; the US-Iran Memorandum of Understanding, an executive agreement outside the normal treaty framework; and the US State Department's explicit extraterritorial legal claim against Iranian toll practices announced in a third-country capital.

Classification: SECURITIZED

The transit passage norm has been securitized, extraordinary measures are legitimized and operational, but the securitization is contested rather than consensual. Iran, the US, the IMO, and Asian importers operate with different primary referent objects, producing a multi-party securitization landscape rather than a unified emergency frame.

Process Tracing Analysis

Cause and Outcome: Cause: the US-Israel joint military campaign against Iran beginning February 28, 2026. Outcome: the stranding of more than 11,000 civilian seafarers on approximately 600 vessels, 14 deaths, the largest oil supply shock in recorded history, and a four-month governance vacuum before a multinational evacuation framework was established.

Causal Mechanism Chain:

Step 1, Tankers and cargo ships became stuck in the Persian Gulf when the US and Israel attacked Iran on February 28.

Step 2, Iran responded by closing the strait and conducting attacks on commercial shipping; 46 incidents involving ships were confirmed between late February and June 11, resulting in 14 fatalities.

Step 3, Commercial shipping, operating under peacetime insurance and routing assumptions, had no standing protocol for active conflict stranding; the IMO lacked authority to negotiate passage with belligerents.

Step 4, The IMO Council called for a safe maritime framework in March as an urgent measure; IMO proposed an evacuation plan but its implementation required political conditions that did not yet exist.

Step 5, The US-Iran MOU, signed around June 15, created the political precondition; the evacuation plan was activated after the MOU signing, with Dominguez noting on June 15 that implementation would require additional time to ensure safety guarantees were in place.

Step 6, The large-scale evacuation operation was launched June 23 in close cooperation with Iran, Oman, all coastal states, the US, and the maritime industry, with safety guarantees secured and navigation conditions verified.

Evidence Assessment:

• Iran's closure as a direct response to the US-Israeli attack: smoking gun, multiple sources directly link the closure to the February 28 attacks.
• No pre-existing evacuation protocol: hoop test passed, IMO's explicit "no precedent" framing and the three-month gap between first Council resolution and actual evacuation launch confirm absence of standing mechanism.
• MOU as necessary precondition: hoop test, evacuation launch was explicitly conditioned on peace agreement per all reporting; no corridor was established before the MOU.
• Mine contamination as physical barrier independent of diplomacy: straw in the wind, Rubio testimony and Oman Navy bulletin are consistent with mine contamination as a physical constraint, but public hydrographic data is unavailable.

CAUSAL_MECHANISM_STRENGTH: MODERATE

The core causal chain is well-supported across government, UN agency, and trade press references. The weaker links are the precise decision calculus within Iran on when to close and when to negotiate (agency is not fully observable from open sources) and the forward-looking link between mine clearance pace and supply normalization timelines, where physical data is unavailable.

Constructivism Lens Analysis

Actor Identities: Iran projected the identity of a sovereign victim of aggression, constructing its nuclear program and territorial integrity as legitimate referent objects deserving of extraordinary defensive measures. The United States projected the identity of rules-based order enforcer, with Rubio's UAE remarks positioning Washington as the guarantor of UNCLOS norms. The IMO projected a technocratic neutral identity, politically non-aligned, focused exclusively on seafarer welfare and navigation safety, a positioning that gave it legitimacy to negotiate simultaneously with belligerents. Oman projected an established intermediary identity: trusted by both parties, geographically adjacent to the strait, and historically a channel for US-Iran back-channel communication.

Operative Norms: Two norms were in direct tension. The norm of freedom of transit passage through international straits, embedded in UNCLOS Part III and reinforced by decades of US Naval operations, treats Hormuz as a global commons through which all states have the right of unimpeded transit. The norm of sovereign self-defense, Articles 51 of the UN Charter, holds that states under armed attack may take proportionate defensive measures. Iran's closure was simultaneously a claimed exercise of the second norm and a violation of the first. The international community's inability to resolve this tension quickly explains the four-month governance paralysis.

Intersubjective Meaning: Iran framed the closure as legitimate wartime response and resisted framing it as economic coercion, even as global oil markets priced it as exactly that. The US and its allies framed Iran as a rogue actor violating international waterway norms. Asian importing nations, China, India, Japan, South Korea, occupied an ambiguous shared understanding: dependent on US-maintained freedom-of-navigation norms but also dependent on Iranian cooperation for reopening, producing hedged diplomatic postures that complicated coalition pressure on Tehran. Natural gas prices in Asian markets rose sharply as buyers competed for a smaller pool of LNG cargoes, reflecting the region's greater exposure to supply disruptions via the Strait , a material pressure that shaped Asian governments' intersubjective framing of the crisis as an emergency requiring resolution, not a principled stand on navigation rights.

Norm Lifecycle Stage: The freedom-of-transit norm for the Strait of Hormuz has moved from near-internalization (the pre-2026 assumption that the norm was self-enforcing) into active contestation. Iran's toll ambitions, even if temporarily suspended, represent a challenge not only to free passage but to the underlying premise that no state can extract economic rent from a chokepoint it physically controls. The UNCLOS framework has no enforcement mechanism against a determined coastal state; the normative architecture is entirely dependent on great-power willingness to enforce it. Secretary Rubio's speech act in the UAE was an attempt to restabilize the norm through reaffirmation, the classic response at the contestation stage, but whether it succeeds depends on whether Asian importers join the enforcement coalition or quietly accept dues as a commercial reality.

Norm Lifecycle: EROSION

The transit passage norm is not yet in cascade collapse, but the combination of demonstrated physical capability (mining), demonstrated willingness to close (execution), and ongoing toll-ambition signals represent a qualitative shift from internalization to erosion.

What-If Analysis

Variable 1: What if the Houthis had activated Bab el-Mandeb closure simultaneously?

The Maritime Executive's June 2026 analysis noted that Houthis did not disrupt Red Sea traffic despite IRGC pressure, focused instead on a life-saving financial deal with Saudi Arabia. What if that calculus had been different? Simultaneous closure of Hormuz and Bab el-Mandeb would have eliminated both export routes for Gulf energy without any viable alternative routing sufficient to replace the volume. With crude and oil product flows through the Strait of Hormuz plunging from around 20 million barrels per day to a trickle, and limited capacity available to bypass the waterway, Gulf countries cut total oil production by at least 10 million barrels per day. A simultaneous Bab el-Mandeb closure would have amplified this by blocking the Red Sea pipeline alternative and the Cape-routed tanker workaround simultaneously. First-order effect: oil prices would moderate-to-high confidence have approached or exceeded $150-160/bbl rather than the $144 peak recorded in late April. Second-order effect: demand destruction would have been more acute and faster-arriving, with airline insolvencies, industrial shutdowns, and food security crises materializing within weeks rather than months. Third-order effect: the political coalition holding US-Iran negotiations together would have faced existential strain, with Asian importers experiencing near-crisis pressure to negotiate bilateral deals with Tehran outside the US framework. The assessment's reliance on Houthi restraint is therefore a genuine vulnerability in the scenario analysis.

Variable 2: What if the 60-day toll moratorium expires without a permanent free-transit settlement?

Diplomatic engagements between Washington and Tehran are proceeding following talks in Switzerland that initiated a 60-day window focused on achieving a permanent resolution. What if those negotiations stall? Iran's ambassador stated the strait is open "without tolls", but the time-bounded framing noted in community reporting on the NewKerala coverage implies a post-moratorium cliff. If Iran moves to formalize navigation dues at moratorium expiration, the US faces a choice: contest the dues through legal challenge (slow, uncertain) or accept them as a fait accompli. Asian importers would face a parallel choice between principle and supply security. If dues are normalized commercially before a legal framework challenge succeeds, the UNCLOS transit passage norm is effectively suspended at the world's most strategically important chokepoint. This would then provide a template that other coastal states, at the Turkish Straits, the Malacca Strait, the Bab el-Mandeb, could invoke. The assessment that the toll dispute is resolved should be treated as provisional until the 60-day window closes without an incident.

Variable 3: What if IRGC capability reconstitutes faster than assumed?

The Maritime Executive noted that Iranian drone and missile sites were pre-positioned for rapid recovery and that some sites were already being rebuilt. The IEA's May 2026 report explicitly noted that removal of Iranian sea mines is a prerequisite for supply normalization , mines that Iran retains the capability to replace if political conditions change. What if the MOU breaks down, as it briefly did when fresh closures were announced following Israeli-Hezbollah hostilities per ANI News, and Iran re-mines cleared sections of the strait? The mine clearance timeline, which the IEA estimated at 6-8 months in the best case, would reset. The operational and financial implications are severe: shipping operators who had begun normal voyage planning would face sudden route cancellation; energy prices would reprice sharply upward; war-risk premiums would immediately return to peak-conflict levels. This variable is not very low confidence, Tehran has already demonstrated willingness to announce a fresh closure following renewed hostilities , and risk managers should treat the current corridor as fragile rather than stable.
