The article is an energy/geopolitics explainer (matching an Al Jazeera piece published 22 February 2026, https://www.aljazeera.com/news/2026/2/22/iran-us-tensions-what-would-blocking-strait-of-hormuz-mean-for-oil-lng) about the Strait of Hormuz amid a US–Iran escalation. Its core quantitative claims are strongly corroborated by primary energy-agency data: the ~20 million barrels per day 2024 transit figure, the 84% crude / 83% LNG Asia destination split, the 69% combined China–India–Japan–South Korea share, the ~20% global LNG share dominated by Qatar, Saudi Arabia's ~5.5 million bpd, the ~33km narrowest width, and the ~3,000 vessels per month figure all match EIA, IEA, IMO/Lloyd's List-derived reporting. Contextual claims are also verified: Iran's announced temporary closure of parts of the strait during IRGC live-fire drills (16–17 February 2026), the USS Gerald R Ford's deployment towards the region alongside the USS Abraham Lincoln, the characterisation of the US posture as the largest regional build-up since the 2003 invasion of Iraq, Trump's public statement that he was 'considering' limited strikes, and the Houthi rally slogan. Deductions arise from three areas: (1) attribution slippage – the Iranian export figure of ~1.7 million bpd for H1 2025 traces to IEA-sourced reporting rather than clearly to the EIA, and the '90% to China' share is corroborated by tanker-tracking analysts rather than the EIA; (2) a contested constitutional detail – Iranian officials stated after the June 2025 parliamentary vote that the final decision on closure rests with the Supreme National Security Council, whereas the article attributes it solely to Supreme Leader Ali Khamenei; and (3) unsourced national dependency percentages for India, Japan and South Korea, which are directionally plausible but not matched precisely by available public data. Presentational bias is limited but present, chiefly the unattributed editorial descriptor 'genocidal war on Gaza' and framing language such as 'in Washington's crosshairs'. No claim met the evidentiary threshold to be adjudicated False.

✕ Disputed claims 2 claims ⌄

DISPUTED (not adjudicated false): 'Any final decision rests with Supreme Leader Ali Khamenei.' Following the June 2025 parliamentary vote, IRGC commander and parliamentary security committee member Ismail Kowsari stated that the final decision lies with Iran's Supreme National Security Council (Newsweek, 22 June 2025, https://www.newsweek.com/iran-parliament-vote-close-straits-hormuz-us-attacks-2088968; Anadolu Agency, https://www.aa.com.tr/en/middle-east/iran-s-parliament-approves-closure-of-hormuz-strait-after-us-strikes-on-nuclear-sites/3608665). Other outlets state Khamenei must approve the action (The National Interest, https://nationalinterest.org/blog/buzz/irans-parliament-just-voted-to-close-the-strait-of-hormuz). Because the Supreme Leader sits above the SNSC in Iran's decision chain, the article's formulation is an oversimplification rather than a demonstrable falsehood; graded Disputed under the false-claim evidentiary guardrail.
DISPUTED (contested characterisation, not a verifiable fact): the descriptor 'Israel's genocidal war on Gaza' is presented in the outlet's own voice without attribution. The genocide characterisation is legally and politically contested and is an editorial judgement rather than an adjudicated factual finding; it is treated here as a presentational/bias issue rather than a false factual claim.

? Unverified claims 10 claims ⌄

The claim that Hormuz transit 'equates to nearly $500bn in annual energy trade' – this valuation appears only in the article itself and syndications of it; no independent primary dataset located in this research window. Unverified (attribution and methodology unclear).
The claim that Iran's oil exports averaged roughly 1.7 million bpd in H1 2025 'according to the EIA' – the 1.7 million bpd H1 2025 figure is attributed in available reporting to the IEA (https://www.tradeimex.in/blogs/iran-oil-export-data-by-country-and-production-stats), while Kpler-based reporting gives ~1.4 million bpd of Iranian crude/condensate to China in H1 2025 (https://www.iranintl.com/en/202506272976). The magnitude is plausible; the EIA attribution is Unverified.
The claim that about 90% of Iran's oil exports go to China – directionally supported by FDD tanker-tracking analysis putting China at 90.6% of exports in October 2025 (https://www.fdd.org/analysis/2025/11/05/irans-october-oil-exports-hit-2025-peak-reflecting-failure-of-u-s-sanctions-enforcement/), but not confirmed as an EIA figure for the stated period. Unverified attribution.
The quoted assertion that around 70% of OPEC+ spare production capacity sits in the Gulf – this is an attributed expert statement; available breakdowns concentrate spare capacity in Saudi Arabia, the UAE, Kuwait and Iraq (https://saudienergyconsulting.com/insights/articles/saudi-arabias-opec-spare-capacity-in-2026-the-high-stakes-balance-between-cuts-and-market-share), which is broadly consistent but does not confirm the exact 70% figure. Unverified as a precise statistic; correctly framed as a quotation.
The claim that almost half of India's crude oil imports and about 60% of its natural gas supplies move through the Strait of Hormuz – Indian policy analysis gives different framings (e.g., India imports ~88% of crude and ~51% of natural gas overall, with ~60% of LPG consumption imported and ~90% of that via Hormuz: https://www.impriindia.com/insights/policy-update/india-strait-of-hormuz-crisis/ and https://www.india-briefing.com/news/indias-oil-supply-hormuz-diversification-strategy-43381.html/). Directionally plausible, precise figures Unverified.
The claims that South Korea sources roughly 60% of its crude and Japan close to three-quarters of its oil via the strait – destination-share data (South Korea 12.0%, Japan 10.9% of Hormuz crude flows: https://www.visualcapitalist.com/charted-oil-trade-through-the-strait-of-hormuz-by-country/) does not directly confirm national import-dependency percentages. Unverified.
The claim that the strait is 'roughly 50km (31 miles) wide at its entrance and exit' – widely repeated in general reference material but not confirmed against a hydrographic primary source in this research window; note the IEA describes the narrowest point as 29 nautical miles (54km), reflecting differing measurement conventions (https://www.iea.org/about/oil-security-and-emergency-response/strait-of-hormuz). Unverified/definitional ambiguity.
The description of Samuel Ramani as an associate fellow at the Royal United Services Institute – not independently confirmed in this research window; treat as Unverified pending a check of RUSI's staff directory.
The implicit currency of the framing ('this month', 'heading to the Gulf') – the article is time-stamped to late February 2026 and has since been overtaken by events, including subsequent hostilities and a sharp collapse in Hormuz transit volumes reported by the EIA for Q1–Q2 2026 (https://www.eia.gov/outlooks/steo/report/global_oil.php). The claims were accurate at publication but are now time-lapsed rather than false.
The characterisation of the USS Gerald R Ford as 'the world's largest warship' – a standard descriptor for the Ford class in defence reporting, but not verified here against an authoritative naval registry. Unverified (low materiality).

⌕ Sources & how we checked Search journal, source grades, confidence ⌄

Confidence

High (0.84) — Confidence is high because the article's load-bearing quantitative claims were verified against primary energy-agency publications (EIA Today in Energy, EIA Short-Term Energy Outlook, IEA chokepoint factsheet) and its principal news claims were confirmed by three or more independent, dated outlets across differing editorial traditions (CGTN, Times of Israel/AP, The National, ABC News, Stars and Stripes, USNI News, CNBC, Scripps News). Twenty distinct queries across five research iterations produced consistent corroboration with no contradictions on the central facts. Confidence is held below 0.90 rather than higher for four reasons: several trade-data sources (Lloyd's List Intelligence, Kpler, Energy Intelligence) were reachable only through secondary reporting rather than direct retrieval; the article's own hyperlinks were stripped, preventing verification of what it actually cited; a cluster of national dependency percentages and the $500bn valuation could not be traced to any dataset, leaving roughly a third of the numerical claims Unverified; and the subject matter is fast-moving, with the situation materially transformed since the article's February 2026 date, which raises the risk that any residual live claim is time-lapsed. The two Disputed items were deliberately not adjudicated False under the stated evidentiary guardrail, which slightly widens the uncertainty band around the final score.

Whenever tensions rise between Iran and the United States, one narrow waterway moves to the centre of global attention – the Strait of Hormuz.

The world’s largest warship, the nuclear-powered aircraft carrier USS Gerald R Ford, is heading to the Gulf, joining one of the largest US military [build-ups]( in the region since the 2003 invasion of Iraq. This time, Iran is in Washington’s crosshairs.

This month, Tehran signalled how it might respond to an attack when it announced the temporary closure of sections of the Strait of Hormuz, the narrow gateway linking the Gulf to open seas.

Iranian authorities carried out live-fire military drills in the corridor, through which about 20 percent of global oil supplies are shipped.

The move marked a rare suspension of activity in parts of the strait. It served as a pointed warning about the economic consequences if Washington proceeds with its threats to strike Iran, highlighting how quickly a regional confrontation could spill into global markets.

## Where is the Strait of Hormuz?

The Strait of Hormuz is the world’s most critical oil chokepoint.

The curved waterway lies between Iran to the north and Oman and the United Arab Emirates to the south. It is roughly 50km (31 miles) wide at its entrance and exit and narrows to about 33km (20 miles) at its tightest point. It forms the only maritime link between the Gulf and the Arabian Sea.

Despite its narrow width, the channel accommodates the world’s largest crude carriers. Major Middle Eastern oil and gas exporters rely on it to move supplies to international markets while importing nations depend on its uninterrupted operation.

## How much oil and gas pass through the strait?

According to the US [Energy Information Administration]( (EIA), about 20 million barrels of oil transited through the Strait of Hormuz each day in 2024. That equates to nearly $500bn in annual energy trade, underlining the waterway’s central role in the global economy.

The crude passing through the strait originates from Iran, Iraq, Kuwait, Qatar, Saudi Arabia and the UAE.

Any prolonged disruption would rattle producers and the economies that depend on their exports.

The strait also plays a critical role in the liquefied natural gas (LNG) trade. In 2024, roughly a fifth of global LNG shipments moved through the corridor with Qatar accounting for the vast majority of those volumes, according to EIA [data](

## Where does it all go?

The strait handles LNG flows in both directions. Kuwait and the UAE import supplies sourced outside the Gulf, including shipments from the US and West Africa.

The EIA estimated that in 2024, 84 percent of crude oil and condensate shipments transiting the strait headed to Asian markets. A similar pattern appears in the gas trade with 83 percent of LNG volumes moving through the Strait of Hormuz destined for Asia.

China, India, Japan and South Korea accounted for a combined 69 percent intake of all crude oil and condensate flows through the strait last year. Their factories, transport networks and power grids depend on uninterrupted Gulf energy.

## What are Iran’s options?

Under international law, states may exercise sovereignty up to 12 nautical miles (22km) from their coastlines. At its narrowest stretch, the Strait of Hormuz and its designated shipping lanes fall entirely within the territorial waters of Iran and Oman.

That legal reality gives Tehran geographic leverage. About 3,000 vessels transit the strait each month. If Iran tried to obstruct traffic, one of the most effective tactics would involve deploying naval mines using fast attack boats and submarines.

Tehran’s fleet includes fast boats equipped with antiship missiles, alongside surface vessels, semisubmersible craft and submarines designed for asymmetric warfare.

Iran’s [parliament]( last year approved a motion to close the Strait of Hormuz. Any final decision rests with Supreme Leader Ali Khamenei.

Regional dynamics could further complicate the situation.

In Yemen, the Houthi group, which maintains close ties with Iran, could again try to disrupt traffic through the Bab al-Mandab Strait, another vital maritime chokepoint linking the Red Sea to global trade routes. Shipping through that corridor suffered significant disruptions after Israel’s genocidal war on Gaza began in October 2023.

The Houthis, who control northwestern Yemen, including the capital, Sanaa, recently [organised]( a mass rally under the slogan Steadfast and Ready for the Next Round, signalling readiness for a potential confrontation with domestic or foreign adversaries.

Any coordinated pressure on the Strait of Hormuz and Bab al-Mandab Strait would amplify risks for global shipping, energy markets and international trade.

## Impact on global oil prices

Colby Connelly, head of Middle East content at Energy Intelligence, told Al Jazeera from the UAE that a full or partial closure of the Strait of Hormuz would have a “major impact on oil prices in the near term”, depending on how long the strait remains contested.

“There are no other major sources of supply that can make up for what comes from the Gulf, especially given the consideration that around 70 percent of OPEC+ spare production capacity sits in the Gulf,” Connelly said, referring to the group of oil-producing countries that collectively sets production volumes.

Saudi Arabia relies heavily on the strait to export its crude, shipping roughly 5.5 million barrels per day through the corridor – more than any other country in the region, according to EIA data.

Iran’s oil exports, about 90 percent of which go to China, averaged roughly 1.7 million barrels per day in the first half of 2025, according to the EIA.

“Saudi Arabia and the UAE both have limited pipeline capacity that can allow exports to continue via the Red Sea coast and Fujairah,” a UAE port on the Gulf of Oman, Connelly warned.

While some Gulf producers hold substantial volumes in overseas storage that could cushion supply shocks, Connelly noted that buffers may prove limited in the face of serious disruptions. He cautioned: “Oil prices have been highly reactive to geopolitical tensions in recent weeks, and as a result, prices could spike to well over $100 per barrel if there were to be a major disruption.”

## Impact on global economy

Any disruption to energy flows through Hormuz would drive up fuel and factory costs, especially as China leans on manufacturing and exports to sustain its economic growth.

Higher energy prices would raise production expenses with companies likely passing those costs along supply chains and to consumers.

“That’s going to have severe inflationary effects for the global economy,” warned Samuel Ramani, an associate fellow at the Royal United Services Institute in the United Kingdom.

The consequences would extend beyond China. Several major Asian economies depend heavily on shipments transiting through the strait.

Almost half of India’s crude oil imports and about 60 percent of its natural gas supplies move through the Strait of Hormuz. South Korea sources roughly 60 percent of its crude via the same route while Japan relies on it for close to three-quarters of its oil imports.

“For the Gulf countries in particular, it’s going to cause a lot of disruption,” Ramani told Al Jazeera. “I was in the UAE recently, and investors in Dubai are concerned about what that would mean for the tourism and finance sector. This may cause some investment hiccups in some of the Vision 2030 projects in Saudi Arabia.”

“There’s many, many layers of concern here, not just exports and prices but also broader macroeconomic and microeconomic consequences. So we should be looking at this as a very serious adverse financial development,” Ramani added.
