Flows through the strait have swung between 3.7 million and 6.4 million barrels a day since mid-July, against about 9 million before. The hedge is against variance, not closure.

Compiled by The InvestorSomething wrong?How this is made
Oil moving through the Strait of Hormuz ran at about 9 million barrels per day until the week ending July 13, and has since oscillated between 3.7 million and 6.4 million b/d as attacks on commercial vessels intensified, according to Kpler data published by Semafor in a column by Amena, an analyst at the firm [1][2]. That range, not the tail risk of a full closure, is the operative problem: the strait is functioning at somewhere between 41 and 71 percent of its recent throughput depending on the week, a spread of 2.7 million b/d [3][4].
The mechanism is repetitive. Since the war between the US and Iran began, more than 170 days ago, supply has come in bursts whenever there is a brief lull and contracted sharply when tensions return, per the same Kpler read [5][6]. President Trump has claimed the US controls the waterway; flows remain well below prewar levels and nowhere near consistent [7]. The column's argument is that the lack of transparency matters less than the possibility that this limbo hardens into the base case [8].
On cumulative damage, the column puts lost regional supply at about 2.5 billion barrels so far, with industry executives not expecting full recovery for at least 18 months [9][10]. Note the arithmetic: 2.5 billion barrels across 170-plus days averages roughly 14.7 million b/d, above the 9 million b/d that had been transiting Hormuz, so the figure is measuring regional supply loss broadly rather than the strait alone [11]. From an August 2026 vantage, "at least 18 months" means no clean run before early 2028 [12].
Demand forecasting has broken down in a way that should temper anyone's conviction. The IEA now sees global demand shrinking 1.5 million b/d this year to 103.3 million b/d; OPEC, having revised down, still expects growth of about 600,000 b/d [13][14]. That is a 2.1 million b/d disagreement about the current year [15]. For next year the three views converge: 2.4 million b/d of growth from the IEA, about 2.2 million from OPEC, around 2.1 million from Kpler [16].
The swing factor named in the column is China, which built reserves over the past 18 months, cut imports, drew down stocks, and has not used its leverage with Tehran to push for reopening [17]. Kpler estimates Chinese crude intake rises by almost 1 million b/d to 13.54 million b/d by October [18]. That increment is roughly 1.7 times OPEC's entire projected global demand growth for the year, which is the whole point: Beijing gets to choose the timing of a shock [19].
Two structural questions sit underneath. Most Gulf states reject an Iranian toll on transiting vessels, though the column argues that states without alternative export routes may be pushed to reconsider [20]. And Houthi attacks on Saudi vessels in Bab el-Mandeb have spread the risk beyond Hormuz [21]. Anwar Gargash, diplomatic adviser to the UAE president, posted last week that the region "cannot remain indefinitely in a state of neither war nor peace" [22].
Watch the weekly flow band rather than the headline: a floor that rises off 3.7 million b/d is the only evidence that the pattern is breaking. Watch whether any Gulf exporter without a pipeline alternative softens on the toll question, which would price transit risk explicitly. And watch Chinese import volumes around the US midterms, which the column flags as a deliberate signal if Beijing chooses to send one [23].

Ranked by verification strength, evidence, and original report placement.
Oil flows through Hormuz were running at around 9 million barrels per day until the week ending July 13, according to Kpler data.
Since the week ending July 13, Hormuz flows have fluctuated between 3.7 million and 6.4 million b/d as attacks on commercial vessels have intensified; the Semafor column is authored by Amena, who works at the energy research firm Kpler.
President Donald Trump may claim that the US controls the waterway, but oil flows remain far below prewar levels and even further from anything resembling consistency.
While the lack of transparency about the status of the strait is a concern, the bigger risk is that uncertainty becomes the new reality; the strait is neither fully open nor fully closed.
The International Energy Agency estimates global oil demand will shrink by 1.5 million b/d this year to 103.3 million b/d.
OPEC has revised down its forecast but still expects consumption to grow by about 600,000 b/d this year.
Evidence-backed comparisons of source perspectives and observed adoption signals. Read the methodology
Which Builder, Operator, and Investor concerns the observed source mix emphasized—not a truth score.
Evidence, demonstrated adoption, hype gap, incentives, and confidence are assessed independently, each on its own current evidence. How these are measured.
Specific numbers, one conflicted source, one internal contradiction
The cluster is a single opinion column. Its load-bearing figures — flow ranges, cumulative losses, China's October intake — are proprietary estimates from the author's own employer, with no independent corroboration in the cluster. Third-party figures (IEA, OPEC) are relayed without report citations, the at-least-18-month recovery horizon rests on unnamed 'industry executives', and the 2.5-billion-barrel loss claim fails a check against the column's own ~9 million b/d baseline. Quantitative specificity and disclosed provenance keep this above the floor; single-sourcing and the unreconciled arithmetic cap it well below the midpoint.
No adoption-type evidence in scope
This is a geopolitical and commodity-market analysis; the supplied material contains no releases, deployments, benchmarks, pricing or licensing events, and no disclosed uptake of any product, standard or method. Behavioural indicators that might substitute — cargo counts, hedging volumes, insurance take-up, rerouting decisions — are not reported, so adoption cannot be measured rather than being low.
Framing runs modestly ahead of what is shown
The core observation is well quantified and the column is explicit about its own uncertainty ('it remains to be seen'), which limits overstatement. But 'top risk', 'the worst oil supply disruption in history' and a 2.5-billion-barrel loss figure are asserted rather than demonstrated, and that figure does not survive arithmetic against the column's own baseline. Price effects are predicted without a single price, freight or insurance datapoint. The gap is real but small and mostly a matter of unsupported magnitude, not of a fabricated phenomenon.
Disclosed vendor-analyst conflict throughout
The author is Head of Middle East Energy & OPEC+ research at Kpler, and Kpler data supply the flow ranges, the China intake projection and one of the three next-year demand forecasts. A commodity trade-intelligence firm benefits commercially when opacity and variance in a chokepoint are read as the enduring condition requiring paid visibility. The conflict is clearly disclosed in-line and in the byline, and the analysis includes figures that cut against a maximal-alarm read, so this is a strong but transparent incentive rather than a concealed one.
Direction credible, magnitudes shaky
Confidence is limited by structure more than by content: one publisher, one author, one data provider, and no way inside the cluster to test the numbers. The directional claim — that Hormuz is functioning intermittently well below prewar throughput — is stated with enough specificity and internal consistency to be relied on cautiously. The cumulative-loss magnitude, the recovery timeline and the Gulf-toll and Bab el-Mandeb assertions should not be, until corroborated.
