Avi Salzman — Oil Is Quietly Slipping Through the Strait of Hormuz. It's Keeping a Lid on Prices. (Barron's, Aug 2026)

One-line take: A macro-only flow piece — no securities are named, and the two firms quoted (Capital Economics, Goldman Sachs) appear as analysts, not as picks. The finding is that the blockade has been routed around rather than lifted. Capital Economics economist Kieran Tompkins estimates Persian Gulf flows — strait plus alternate exits — have "rebounded to about 80% of prewar levels," leaving "a not-so-bad equilibrium" that explains why Brent trades around $89 despite "little progress in negotiations between the U.S. and Iran." Goldman's Daan Struyven puts combined crude-and-product outflows at 15–16 million barrels a day, still 7–8 mb/d below prewar, with strait traffic at 8–10 mb/d — roughly half its prewar level; the gap is being closed by adaptation rather than by new supply: night transits with "tracking devices turned off, aided by the U.S. military," then ship-to-ship transfers onto tankers bound for Asia, plus routes around the strait or out through the Red Sea. "The rise in dark crossings by specialized shippers and in ship-to-ship transfers shows that producers and shippers are adapting to the Mideast conflict." The forward-looking tell is a price, but not the oil price: "elevated shipping rates indicate that oil companies are preparing for the strait to remain at least partially closed into next year" — the freight market pricing the blockade's duration. The investment conclusion follows from the equilibrium: because crude is stuck in this "strange semi-equilibrium," Goldman is advising clients to "turn to other products to hedge against geopolitical disruption," recommending diesel futures — diesel has run hotter than crude because refineries in Russia, the Middle East and China are operating at reduced capacity amid the Iran and Ukraine wars — and expecting LNG prices to remain high on short global supply and Europe's winter stockpiling. For the consumer: rebounding Gulf supply "could keep gasoline prices from jumping in the near term, though consumers shouldn't expect much near-term relief at the pump." (Views are Tompkins' and Struyven's as reported by Salzman, not a Barron's rating.)

1. Stocks & names mentioned

This is a pure oil-flows / commodities piece. Salzman names no public companies or tickers — only the research houses whose analysts are quoted (Capital Economics, Goldman Sachs), countries and waterways (Iran, Russia, China, the Middle East, Ukraine, Europe, Asia, the Strait of Hormuz, the Arabian Sea, the Red Sea), and the instruments Goldman discusses (Brent crude, diesel futures, LNG). There is no stock table for this article; the substance is in the key points below. Goldman's recommendation is a futures hedge rather than an equity, so it is deliberately left untickered — the archive records a row only where the writer names a listed security.

2. Talking points

The headline finding — flows at a one-month high, prices capped

"Oil is flowing out of the Persian Gulf region at its highest levels in more than a month, analysts say, keeping a lid on prices even as the Iran war is far from resolved."
The causal claim is worth stating plainly: what is capping prices is neither diplomacy nor demand destruction — it is logistics. The barrels found a way out.

"Not-so-bad equilibrium" — Capital Economics' framing

Capital Economics economist Kieran Tompkins: the market is in a "not-so-bad equilibrium" six months into the war.
He estimates flows out of the Persian Gulf — "using the strait and alternate exit routes" — have "rebounded to about 80% of prewar levels."
That is offered as the explanation for the price: Brent around $89 per barrel, "despite little progress in negotiations between the U.S. and Iran." The price has decoupled from the diplomatic track because the physical track resolved itself.

The quantities — Goldman's flow accounting

Goldman Sachs analyst Daan Struyven: crude and oil products leaving the Persian Gulf are back to roughly 15–16 million barrels a day, still 7–8 mb/d below prewar.
Strait traffic specifically is back to about 8–10 mb/d, "roughly half its prewar level." The distinction is the whole article: the strait remains badly impaired; the region's exports are not, because the route mix changed.
Prewar, "almost all of the oil in the Persian Gulf moved out of the strait to the Arabian Sea and then to Asia." Now "countries are using several different routes to get their oil out."

How the barrels are actually getting out — dark crossings

"Many of the ships that are making it through are doing so at night with their tracking devices turned off, aided by the U.S. military."
Once through, "they often transfer the oil to other tankers ready to transport it to Asia" — ship-to-ship transfer as the standard second leg.
Struyven: "The rise in dark crossings by specialized shippers and in ship-to-ship transfers shows that producers and shippers are adapting to the Mideast conflict."
A second-order point for anyone leaning on tanker-tracking data: transponders-off traffic means observed strait volumes now understate real ones. The adaptation degraded the measurement as well as the chokepoint.

The alternate routes

"The other way countries are getting their oil out is by taking alternate routes around the strait, or to the Red Sea on the opposite side of the Middle East."
Geography is doing what price could not: substituting for a chokepoint. Those routes are slower and costlier, which is why flows recover to 80% rather than 100%.

The forward indicator — freight rates, not the oil price

"The bad news is that elevated shipping rates indicate that oil companies are preparing for the strait to remain at least partially closed into next year."
The most portable observation in the piece: the freight market is pricing the duration of the blockade while the crude market prices only today's balance. Tanker rates are the closest thing available to a traded forecast of how long the disruption lasts.

The equilibrium is uneasy in both directions

"Until the war is fully resolved, the market may be in this uneasy equilibrium — enough oil is moving now to keep prices from spiking, but not enough is moving for prices to come down significantly."
A range-bound crude market with a fat tail on each side is the worst environment for a directional crude bet — and the reason the trade migrates somewhere else.

The consumer read — no relief at the pump

"Rebounding supplies from the Persian Gulf could keep gasoline prices from jumping in the near term."
But "consumers shouldn't expect much near-term relief at the pump" — consistent with the archive's Aug 18 and Aug 21 pages, where the binding constraint on pump prices is refining capacity, not crude supply.

The tactical conclusion — hedge geopolitics with diesel, not crude

"For investors, it may also be time to change tactics. Because crude oil is now in this strange semi-equilibrium, Goldman analysts have been advising investors to turn to other products to hedge against geopolitical disruption."
The specific recommendation: "buying diesel futures as one hedge."
The reason is a capacity constraint, not a barrel constraint: "Diesel prices have been more elevated than crude oil, because refineries making it in Russia, the Middle East and China are operating at reduced capacity amid the wars in Iran and Ukraine."
Read against the Aug 18 page (a first-ever triple-digit WTI-to-diesel crack, refiners at all-time highs) and the Aug 26 page (Goehring & Rozencwajg on diesel stockpiles "near tank bottom"), this makes three independent desks pointing at the same bottleneck within eleven days.

The second constrained product — LNG

"Goldman also expects liquefied natural gas prices to remain high, because LNG is in short supply around the world and Europe needs to stockpile more to prepare for winter heating season."
Same structure as the diesel call: a product whose supply is capacity-limited and whose demand carries a calendar deadline (the winter refill) that the buyer cannot defer.
