Strait of Hormuz Transit Risk and Global Energy Supply Chain Resilience: Geopolitical Volatility Impact on Oil Market Pricing and Logistics Routes

Executive Summary

The IEA's Executive Director Fatih Birol described the Hormuz disruption as "the largest supply disruption in the history of the global oil market," and Asia-Pacific energy importers have borne the sharpest end of that shock. Shipping traffic through the Strait was largely blocked by Iran from 28 February 2026 following the U.S.-Israeli air campaign against Iran. As of the third week of June, a U.S.-Iran interim agreement has begun to take effect, but the situation remains volatile, and most vessel operators are taking a wait-and-see approach and delaying entry to the Middle East Gulf. The crisis has split supply-chain strategy into three concurrent tracks: emergency reserve drawdown, alternative sourcing from Atlantic and Russian Basin producers, and structural diversification investment that will outlast the immediate conflict. Readers making procurement, hedging, or capital-allocation decisions should understand that even a full Hormuz reopening will encounter a structurally tighter market than existed before February 2026.

The Asymmetric Exposure Map Across Asia-Pacific

The four major Asia-Pacific importers entered the crisis with markedly different vulnerability profiles, and their responses diverged accordingly. Zero Carbon Analytics, drawing on IEA and EIA data, assigned Japan the highest supply-disruption risk score (6.4 out of 10), followed by South Korea (5.3), India (4.9), and China (4.4) — a hierarchy that maps almost exactly onto the crisis-response intensity observed across the region.

China alone accounts for 37.7% of total crude oil and condensate flows through the Strait, with India at 14.7%, South Korea at 12.0%, and Japan at 10.9%; other Asian countries make up a further 13.9%. Japan's exposure is most acute in proportional terms: Japan gets approximately 90% of its oil shipped through the Strait, leaving it with no short-term substitute when Hormuz closed. South Korea responded by allowing its refiners to conduct crude swaps, borrowing crude from the strategic petroleum reserve and committing to refill it later, according to Vortexa's April tracking analysis. South Korea and China were also, per Vortexa, among the first countries to impose oil-product export restrictions, prioritizing domestic consumption over revenue.

China's response differed structurally. China faces the largest reduction in refinery runs in March due to substantial stock building; however, the country is well positioned to weather prolonged disruptions with its large crude storage cover (west of Hormuz, excluding Iran) of 310 days. The EIA confirmed that China had added an average of 1.1 million barrels per day to strategic inventories throughout 2025, reaching nearly 1.4 billion barrels by December of that year, a stock-building posture that now reads as strategic foresight rather than coincidence.

India's position sits between China's relative resilience and Japan's acute exposure. Indian refiners started buying petroleum from Russia as the war disrupted supplies from the Middle East, and the government raised export duties on diesel and aviation fuel to preserve domestic availability. India's top refining operators absorbed significant margin compression as crude acquisition costs surged, prompting HSBC to downgrade Indian equities in response. The interplay between energy import costs and macroeconomic stability is particularly direct for India: a sustained import-price shock widens the current account deficit and weakens the rupee, amplifying domestic fuel costs in a second-order loop.

The Inventory Drawdown Trajectory And Its Ceiling

Stock-flow analysis is essential here: the headline stock figures mask how rapidly the rate of drawdown has depleted safety margins. Global oil supply declined by a further 1.8 mb/d in April to 95.1 mb/d, taking total losses since February to 12.8 mb/d, with output from Gulf countries affected by the closure running 14.4 mb/d below pre-war levels.

Observed global inventories, including oil on water, were drawn down by 250 million barrels over March and April, or 4 mb/d.

The IEA's June data noted that Hormuz flows had partially recovered from a May low of 9.6 MMbpd to approximately 12 MMbpd in early June, but that figure still represents a substantial shortfall against the pre-conflict baseline of nearly 20 million barrels per day confirmed by the IEA's own chokepoint analysis. The IEA explicitly flagged that operational and political constraints, including prolonged demining and unresolved transit arrangements, leave downside risks to the base-case recovery timeline.

IEA member countries hold 1.25 billion barrels in public strategic stocks, representing approximately 30% of total OECD oil inventories; under normal consumption patterns, these reserves could theoretically supply global markets for approximately 60-90 days, though actual deployment would be partial rather than complete to maintain an emergency buffer. The critical distinction is between the stock level and the drawdown rate: at 4 mb/d of inventory depletion observed in March-April, the IEA's emergency stock ceiling, if fully deployed, would sustain market function for roughly 10 months, but no government is willing to drain reserves to zero, meaning the practical ceiling is materially lower. The IEA's June report confirmed OECD government inventories had fallen 163 million barrels since the conflict began and reached their lowest level since December 1990.

These dynamics compound the existing economic uncertainty already facing Asia-Pacific importers from tariff volatility and dollar-denominated commodity pricing. Both the energy security and macroeconomic implications of sustained inventory drawdown are mutually reinforcing: as commercial buyers scramble for non-Gulf barrels, Atlantic Basin and U.S. producers have raised prices to reflect scarcity premium, which in turn widens the cost gap between pre-crisis procurement and current spot terms.

Alternative Routing, Bypass Economics, And The Atlantic Pivot

The Cape of Good Hope routing option has shifted from contingency plan to operating procedure for supertankers serving Asia-Pacific markets. This rerouting adds roughly 3,500 nautical miles per round trip compared with a Hormuz-Suez corridor passage, translating into additional voyage times of 10 to 14 days depending on vessel type and destination port. VLCC rates reached $800,000 per day at peak disruption during the 2026 closure, representing a significant increase from pre-conflict norms. The Aufman Associates mid-year market assessment noted that diverting VLCCs around the Cape, while expensive, "ensures delivery" and has functioned as a vital shock absorber for the global energy market.

The broader consequence is a permanent re-pricing of delivered energy costs for Asia-Pacific buyers. Norway was reportedly pumping near capacity with its spare output buffer essentially depleted, and global oil inventories drifting toward record lows, suggesting that even a full Hormuz reopening would encounter a structurally tighter global supply environment than existed before February 2026.

On the producer side, Saudi Arabia and the UAE successfully redirected some exports to terminals loading outside of the Strait, using the East-West pipeline and the Habshan-Fujairah corridor respectively. Saudi Aramco reported in March 2025 that it had increased East-West pipeline capacity to 7 mb/d, though sustainable flows have not been tested at that level; as of early 2026, approximately 2 mb/d of the pipeline's capacity was in use, leaving between 3 and 5 mb/d of spare capacity depending on operational conditions. This spare capacity became the primary non-maritime route for Gulf crude reaching Asian buyers, but even at maximum utilization it falls far short of replacing Hormuz volumes.

Iraq has an almost 600-mile pipeline to Turkey with a total capacity of around 1.6 mb/d that had been closed but will reportedly reopen with an initial capacity of 250,000 barrels per day due to the Hormuz disruption. Gulf states have also revived IMEC, the India-Middle East-Europe Economic Corridor, as an overland diversification concept, though its timeline remains measured in years rather than months. The interplay between geopolitical emergency and long-shelved infrastructure projects has, paradoxically, given credibility to overland connectivity schemes that were previously judged too expensive to justify.

Chevron's restart of Wheatstone LNG capacity amid the global gas shortage reflects how non-Gulf producers are responding to the demand signal created by the disruption, and Europe has been accelerating Atlantic Basin and African LNG sourcing, reducing structural dependency on Gulf flows. For Asia-Pacific buyers, the practical alternative has been U.S. LNG, with Japan's Japex announcing major upstream expansion and Asian buyers broadening their U.S. LNG terminal infrastructure.

Hedging Architecture Under Structural Uncertainty

The commodity price and freight-rate volatility generated by the Hormuz disruption has forced Asia-Pacific energy buyers to rethink hedging frameworks that were calibrated for normal-market conditions. When gunfire attacks in the Strait of Hormuz targeted container ships in April 2026, Brent crude futures surged $1.59 per barrel (1.6%) to $100.07 within hours of reported incidents, illustrating both the speed and the magnitude of price transmission from security events to financial markets. According to the IEA's May Oil Market Report, North Sea Dated oil traded in a substantial range of almost $50 per barrel in April, with prices briefly reaching $144 per barrel before falling below $100.

Benchmark oil prices posted volatile swings in response to conflicting signals on whether the United States and Iran would reach a deal, with North Sea Dated plunging from a high of $144/bbl to below $100/bbl before rebounding. This degree of intra-month volatility is structurally hostile to fixed-forward hedging: buyers who locked in contracts at $130 found themselves paying above market within weeks; those who left positions open absorbed the upside volatility. Discovery Alert's maritime security analysis noted that portfolio strategies are increasingly incorporating geographic diversification and volatility hedging instruments designed to protect against supply disruption scenarios.

The insurance dimension is equally material. In the days before the conflict, war-risk ship insurance premiums for the strait increased from 0.125% to between 0.2% and 0.4% of ship insurance value per transit. Discovery Alert's analysis of the IEA's inventory data reported that Lloyd's of London and the international marine insurance market had effectively repriced Hormuz transit risk to near-uninsurable levels at peak disruption, and that reversing that designation requires sustained evidence of physical safety, including completion of demining operations. As of 18 June, Seatrade Maritime reported that the Joint Maritime Information Centre (JMIC) had dropped its threat level in the Strait to "moderate," and Bimco's Chief Safety and Security Officer Jakob Larsen stated publicly that the security situation for the shipping industry "remains volatile" and that shipowners should continue doing thorough risk assessments.

Countries with significant energy import bills may experience balance of payments pressures that weaken their currencies, amplifying the domestic impact of higher international energy prices; effective hedging therefore requires coordinating both commodity price and foreign exchange risk management strategies. This dual-axis exposure, commodity price and currency, is particularly pronounced for South Korea, Japan, and India, all of which run dollar-denominated crude import contracts against domestic-currency revenue streams.

The Normalization Gap: Why Reopening Is Not Restoration

The U.S.-Iran interim agreement signed in mid-June 2026, the Islamabad Memorandum of Understanding, has generated market optimism, with Brent declining on the news and tanker traffic beginning to resume. With the Strait of Hormuz remaining mostly closed since the beginning of the conflict, about 17.7 mb/d of mainstream seaborne oil supplies (excluding those from Iran) have been curtailed from the market. Restoring that flow to pre-conflict levels requires more than a political agreement.

Businesses that were managing disruption as a short-term event are now planning for sustained alternative routing through the second half of 2026. The IEA's June assessment was explicit that demining operations, naval mine clearance in and around Hormuz shipping lanes, require coordinated multi-party activity and weeks of dedicated operations before commercial vessels can transit under insurance terms. Vessel traffic management, naval escort arrangements, and insurance underwriting frameworks must all be rebuilt from scratch, according to the IEA's detailed operational assessment.

The broader supply picture underscores why normalization timelines matter. The IEA projects global oil supply will decline by 3.9 mb/d to 102.4 mb/d for full-year 2026, before rebounding by 8 mb/d in 2027 as Gulf exports resume and non-OPEC+ production growth continues. The 2027 rebound is, in effect, what physical normalization looks like at the supply level, meaning the 2026 average will remain significantly depressed regardless of when Hormuz formally reopens. Gulf producers retain market share but face structural dilution of their pricing leverage as diversification matures across multiple buyer markets.

The 2026 State of Logistics report, titled "Forged in Disruption" and released in June, found that the most successful companies in the current environment are those that have accepted persistent disruption as the baseline operating condition rather than treating it as a temporary deviation, a finding that applies directly to Asia-Pacific energy procurement planning. The EFESO Management Consultants analysis, published in mid-June on Consultancy-me.com, noted that freight rates are capable of increasing by more than 120% in disruption scenarios, and that protecting industrial margins increasingly depends on optimizing transportation networks at a structural rather than transactional level.

Securitization Theory Analysis

Securitizing Actor: The United States, framing the Strait of Hormuz crisis as a direct threat to global economic security and allied energy stability. President Trump publicly cited the need to avoid severe economic consequences in defending the interim Iran deal, according to Oil & Gas 360's June reporting. Japan, South Korea, and other IEA member governments have co-securitized the issue through coordinated strategic reserve releases and emergency supply diplomacy.

Referent Object: The global energy supply chain and, by extension, the economic stability of import-dependent allies. The World Economic Forum's Global Risks Report 2026 frames geoeconomic confrontation, including energy chokepoint risk, as a structural threat to economic and industrial policy systems, not merely a tactical market disruption.

Existential Threat Construction: The framing has consistently emphasized severity. The IEA's Fatih Birol called it "the largest supply disruption in the history of the global oil market." Governments invoked emergency legal authorities to release strategic reserves, tools reserved for crisis conditions under IEA treaty obligations. The Food Policy Institute warned of long-term increases in food prices. These speech acts collectively constructed the Hormuz closure as threatening not just energy prices but the foundation of industrial and food systems.

Target Audience: Multiple audiences simultaneously: domestic publics in Japan and South Korea (justifying rationing and reserve releases), international investors and refinery operators (signaling state-backed supply support), and Iran itself (calibrating the cost of continued closure).

Extraordinary Measures: Coordinated IEA emergency stock releases in March 2026; Japan's release of 80 million barrels from strategic reserves; South Korea's authorization of refinery crude swaps from SPR; India's imposition of fuel export duties; export controls on oil products in South Korea and China; and the full U.S. blockade of Iranian ports from 13 April to 29 May 2026.

Classification: SECURITIZED

The issue moved unambiguously from the political to the securitized register. Extraordinary measures have been not only proposed but deployed at scale across multiple sovereign actors, with near-universal acceptance of emergency frameworks as legitimate responses to the threat.

Process Tracing Analysis

Cause and Outcome: Cause, effective closure of the Strait of Hormuz from late February 2026. Outcome, structural reconfiguration of Asia-Pacific energy procurement, routing, inventory, and hedging strategies.

Causal Mechanism Chain:

1. U.S.-Israeli air campaign against Iran triggers IRGC mine-laying and vessel attacks in the Strait, closing commercial transit lanes.
2. Insurance markets withdraw P&I cover for Hormuz transits, making closure commercially complete even without physical barrier.
3. Gulf crude exports fall sharply; IEA data confirm 14.4 mb/d below pre-war levels by April.
4. Asia-Pacific importers face immediate supply gaps; Japan, Korea, and India cut crude imports by 1.9, 1.0, and 0.76 mb/d respectively (IEA May 2026).
5. Governments activate strategic reserve release protocols, buying 60-90 days of buffer.
6. Commercial buyers redirect vessels to Cape of Good Hope routing, absorbing cost increase of $500,000-$2 million per voyage.
7. Spot crude markets tighten; Brent reaches $144 per barrel intra-month in April.
8. Buyers contract with Atlantic Basin, U.S., and Russian suppliers; structural sourcing diversification begins.
9. Shipping economics, insurance frameworks, and procurement contracts are rewritten around new cost baselines.

Evidence Assessment:

• Smoking gun (confirms mechanism): Vortexa vessel-tracking data showing Japan, South Korea, and Taiwan combined Hormuz crude imports falling from 3.9 mb/d to 0.8-1.1 mb/d; IEA confirmed 250 mb global inventory drawdown in March-April.
• Hoop test (must be present): Insurance withdrawal, confirmed by Lloyd's Market Association and the surge in war-risk premiums from 0.125% to 0.2-0.4%.
• Smoking gun (diversification): Japex announcement of quadrupled upstream production plan; South Korea's crude swap mechanism authorization; Indian refiner pivot to Russian crude (Wikipedia fuel crisis article, April 2026).
• Straw-in-the-wind: Long-term infrastructure proposals (IMEC revival, Iraq-Turkey pipeline reopening) — consistent with structural response but insufficient alone to confirm lasting reconfiguration.

CAUSAL_MECHANISM_STRENGTH: STRONG

Multiple smoking-gun evidence items corroborate the mechanism. Vessel-tracking data, inventory statistics, government policy actions, and financial market movements all align with the posited causal chain, and no alternative mechanism credibly explains the simultaneous reconfiguration across multiple independent actors.

Constructivism Lens Analysis

Actor Identities: Japan and South Korea project the identity of "responsible IEA allies" — accepting the legitimacy of coordinated reserve release and bilateral supply diplomacy. India projects a pragmatic "non-aligned sovereign buyer" identity, pivoting to Russian crude without abandoning Western market relationships. China projects the identity of a "self-insulated strategic actor," having pre-positioned reserves and declined to coordinate emergency releases with Western institutions.

Operative Norms: The IEA emergency coordination norm, built around the 1973-74 oil shock experience, was invoked and broadly honored among OECD members. However, the norm of freedom of navigation, which previously constrained all actors from formally blockading commercial shipping, was visibly contested by both Iran's mine-laying and the U.S. port blockade of Iran from 13 April to 29 May.

Intersubjective Meaning: Among Western-aligned importers, the shared frame is "energy security as national security" — a construction that legitimizes extraordinary fiscal and diplomatic responses. Among Gulf producers, as reported by CNBC in April, Iran's behavior has created what Gulf states described as a "huge trust gap," shifting the relational meaning of Hormuz from "shared economic corridor" to "systemic vulnerability." This discursive shift is likely to prove durable regardless of how quickly tanker traffic resumes.

Norm Lifecycle Stage: The norm of treating Hormuz transit as inviolable, underwritten by U.S. naval presence and implicit deterrence, has been materially tested and partially broken. New norms around energy supply chain resilience, strategic stockpiling, and buyer diversification are in rapid cascade among OECD governments and major importers, as evidenced by the coordinated reserve releases and structural procurement pivots documented across IEA, CNBC, and Seatrade Maritime reporting.

Norm Lifecycle: CASCADE

The pre-existing internalized norm of Hormuz-dependent supply chains is eroding; a replacement norm of resilience-by-design is cascading rapidly through buyer-government policy frameworks, corporate procurement contracts, and infrastructure investment decisions.

What-If Analysis

Variable 1: The U.S.-Iran deal fractures within the 60-day window.

Vance confirmed that the 60-day interim period under the Islamabad MOU began on 18 June 2026. If the deal collapses before a full security agreement is reached, vessel traffic that has tentatively resumed would halt. Seatrade Maritime noted on 22 June that even under the current framework, the Strait's threat level remains at "moderate" with the security situation still described as volatile by Bimco. A deal fracture would trigger: immediate reimposition of war-risk insurance exclusions; reversal of the oil price decline that followed the MOU signing; and renewed pressure on OECD strategic reserves that are already at their lowest levels since December 1990. Asia-Pacific importers with limited reserve cover, particularly Japan and South Korea, would face the most acute second shock. This scenario is observable via a specific indicator: tanker transits through the Traffic Separation Scheme resuming at above 10 per day for sustained weeks would indicate stabilization; a reversion to below 5 per day would signal fracture risk.

Variable 2: China deploys its 310-day strategic reserve buffer to corner discounted non-Gulf crude markets.

China's EIA-documented 1.4 billion barrel reserve gives it the structural ability to absorb a prolonged Hormuz closure far longer than any other Asia-Pacific importer, while simultaneously using that buffer to support domestic industrial activity at reduced refinery runs. If China deploys this buffer aggressively and simultaneously outcompetes Japan, South Korea, and India for Atlantic Basin and Russian crude volumes, it would compress the available non-Gulf supply for those less-buffered buyers. The cascading effect would be tighter non-Gulf spot markets and higher prices for the very alternative barrels that Japan and Korea are depending on. The signal to watch is China's crude import data from non-Gulf sources in June and July: if Chinese purchases of Atlantic Basin, U.S., and Russian crude accelerate above the pre-crisis baseline, the competition for replacement barrels is intensifying.

Variable 3: LNG infrastructure investment committed during the crisis proves structurally oversized if Hormuz normalizes faster than expected.

The crisis has triggered major infrastructure commitments, Japex's planned upstream expansion, expanded U.S. LNG terminal contracting by Asian buyers, and accelerated pipeline investment across the Gulf. If Hormuz returns to full operational capacity by mid-2027 and Qatar resumes full LNG exports, the capital committed to alternative supply infrastructure will face lower-than-projected utilization rates. This is not necessarily negative, redundancy has strategic value, but it does create write-down risk for utilities and trading companies that committed to long-term take-or-pay LNG contracts during the crisis at crisis-era pricing. The discriminating indicator here is spot LNG prices: if Asian spot LNG reverts below $12/MMBtu within 18 months of full Hormuz normalization, the premium embedded in crisis-era long-term contracts will become a financial liability for buyers.

Counterarguments

1. The normalization narrative is moving faster than the structural diversification story warrants. The June 2026 oil price decline following the Islamabad MOU has generated market signals of rapid normalization. But Bimco, Lloyd's Market Association, and Intertanko have all explicitly warned that operational reality lags diplomatic reality by months. The argument that "markets have largely priced in reopening" risks confusing the removal of tail-risk premium with the restoration of physical supply chains. A corporate strategist who reduces Hormuz-risk hedging now because of MOU optimism is assuming that demining, escort protocols, and underwriting frameworks will be rebuilt faster than historical precedent supports. The 2016 Red Sea mine-clearing after Yemeni conflict, for reference, took eight months to reach commercial-insurer acceptance.

2. The structural diversification argument underestimates path dependency in crude oil procurement. Asian refinery configurations are purpose-built around specific crude grades, Japanese and Korean refineries are heavily configured for Middle Eastern light and medium sour crude. Replacing those volumes with U.S. light sweet or Atlantic Basin grades requires either refinery configuration changes (costly and slow) or blending workarounds (costly and operationally complex). CNBC's April reporting on Gulf producer vulnerability noted that even Saudi Arabia and UAE, which have alternative export routes, have been unable to fully replace lost volumes via pipelines. The assumption that buyers can seamlessly pivot to non-Gulf crude at scale may be overestimated in both speed and cost terms.

3. The fertilizer and food security second-order effect remains the least-priced risk in Asia-Pacific strategic planning. The energy and shipping analysis dominates headline coverage, but the Arabian Gulf accounts for at least 20% of all seaborne fertilizer exports, and 46% of global urea trade originates from the region; analysts warn that a prolonged disruption will significantly tighten availability in import-dependent regions, potentially driving up global food production costs and inflationary pressures. This translates directly into political risk in India, Bangladesh, Pakistan, Vietnam, and Indonesia, markets where food price inflation has historically correlated with social instability. Corporate risk managers focused purely on energy input costs may be underweighting the indirect exposure their supply chains carry through agricultural input disruption, particularly for consumer goods companies sourcing from South and Southeast Asia.

Indicators To Watch

Decision Relevance

Scenario A (~55%): Gradual Hormuz normalization over 3-6 months with persistent freight-cost premium — The interim MOU holds, demining proceeds, and commercial traffic resumes at 60-70% of pre-conflict volumes by Q4 2026. Insurance frameworks are partially reinstated. Recommended actions: maintain hedged Cape of Good Hope routing contracts through at least Q1 2027 rather than immediately reverting to Hormuz routing; lock in non-Gulf supply agreements at current pricing rather than speculating on a rapid Hormuz discount; accelerate strategic reserve restocking when spot prices dip on reopening optimism; review refinery configuration exposure to Gulf crude grades and model cost of transitioning to blended alternative-grade feedstocks.

Scenario B (~30%): Deal fracture within the 60-day MOU window, renewed closure — IRGC attacks resume, insurance withdrawal is reimposed, and flows revert to near-zero. OECD strategic reserves have already been partially drawn and cannot sustain a second sustained shock at the same drawdown rate. Recommended actions: immediately review remaining strategic reserve cover against refinery run-rate assumptions; trigger contingency contracts with Atlantic Basin and U.S. producers pre-negotiated for rapid activation; hedge FX exposure alongside commodity price exposure as currency pressures will compound import cost increases; prepare demand-side curtailment plans for energy-intensive industrial operations.

Scenario C (~15%): Faster-than-expected full normalization by end of 2026 — Demining proceeds rapidly, full commercial insurance is reinstated, and Hormuz flows recover to 85%+ of pre-conflict baseline by year-end. Oil prices fall sharply from crisis-era levels. Recommended actions: do not unwind structural diversification investments on price-recovery optimism alone; use the price correction window to restock strategic reserves at lower cost; maintain non-Gulf supply contracts as optionality rather than canceling them; stress-test newly contracted long-term LNG agreements against below-$12/MMBtu JKM scenarios to assess mark-to-market exposure.

Analytical Limitations

• Physical mine-clearance data from Hormuz is not publicly available at the granularity needed to independently validate military assessment timelines. If mines are more numerous or more deeply embedded than coalition naval assessments indicate, the normalization timeline in Scenario A is likely too optimistic, and this assessment would require revision toward Scenario B.

• Refinery-level procurement contracts and crude-grade swap arrangements for Japan, South Korea, and India's major refiners are not publicly disclosed. The cost of transitioning to alternative crude grades depends critically on individual refinery configurations, which this assessment cannot verify. Cost estimates for diversification carry material uncertainty on the downside.

• China's actual strategic reserve deployment rate and current inventory level are state-classified. The EIA estimate of nearly 1.4 billion barrels as of December 2025 is the most authoritative publicly available figure, but China's actual pace of reserve drawdown or addition during the crisis period is unknown. If China has drawn reserves more aggressively than estimated, its buffering capacity is overstated, which would heighten competition for non-Gulf spot barrels and tighten alternative supply markets for Japan and Korea.

• The political durability of the Islamabad MOU's nuclear-adjacent provisions remains unresolved. Seatrade Maritime's June 22 analysis noted that the final agreement has yet to be fully negotiated and that Israel's position has not been incorporated, which creates a structural fragility that no current commercial risk model can fully price.

• All inventory and flow data cited from IEA, Vortexa, and EIA sources carry a 4-to-6-week publication lag relative to field conditions. The June 22 operational picture at Hormuz may differ materially from the most recent published figures.
