Physical Markets Weekly: Diplomacy Repriced Crude While Freight Stayed Extreme

Physical commodity markets ended the week with a widening gap between benchmark-price volatility and the cost of physically executing the trade.

Middle East crude moved sharply in both directions as the market repriced the chance of a diplomatic opening around the Strait of Hormuz. The Dubai prompt premium fell to $17.92/b by September 22, about $12/b lower on the week. November Dubai then surged above $117/b on September 24 and fell back to about $113.29/b the next session. Freight did not follow either move. Persian Gulf-to-China VLCC freight held near w1145, roughly $80/mt above a Gulf of Oman loading.

The rest of the chain moved at three speeds. VLCC earnings paused near $1 million a day. Clean long-range freight and Aframax rates kept rising. European diesel flat prices swung with crude, while ARA diesel and gasoil stocks ended near 1.636 million mt, about 25% below a year earlier, and Middle East diesel into Europe ran at the lowest rate since early 2020. Rhine water at Kaub fell to about 5 cm. Asian gasoil became cheap enough versus Europe to pull barrels west, and Fujairah rebuilt the stock buffer outside the strait.

Agricultural markets were less disrupted by logistics. The strongest weekly move was US soymeal, up roughly $14–20/mt.

Market at a Glance

Benchmark crude swung both ways. Freight did not. The Dubai prompt premium was $17.92/b on September 22. November Dubai was above $117/b on September 24 and about $113.29/b on September 25.
The Persian Gulf location premium is about $80/mt. PG-to-China VLCC freight stayed near w1145, about $238/mt, against roughly w800, or $159/mt, for Gulf of Oman positions.
VLCC freight is near a ceiling, not a normal market. Earnings peaked near $1.019 million/day on September 21 and remained above $1 million. Aframax freight from the US Gulf to the UK Continent reached w625.
Clean tanker pressure intensified while VLCCs paused. Arab Gulf-to-UK Continent LR2 freight reached $156.11/mt. Arab Gulf-to-Japan LR freight rose from w775 to w875.
Yanbu is still not a confirmed loading program. No crude has lifted since September 12. At least 24 million barrels were reported for lifting off the Omani coast in September and October.
European diesel stocks are the constraint. ARA diesel and gasoil inventories were about 1.636 million mt, roughly a quarter below last year. Middle East flows into Europe averaged about 110,000 b/d, the lowest since February 2020.
Export permission is now part of the diesel barrel. Russia's producer ban runs through October. A US blanket export ban was publicly set aside within two days, and the option remains open.
The Rhine is close to stopping barge supply. Kaub fell from about 22 cm on September 18 to about 5 cm, with forecasts near 1 cm around September 29.
Asian gasoil has opened a westbound arbitrage on paper. The East-West spread widened to −$199.82/mt on September 23, the lowest since the marker began in 2009.
Asian jet returned to a premium after a week at a discount. Singapore jet cash was about +$1.48/b by September 24. ARA jet stocks fell back to 510,000 mt.
Fujairah rebuilt the buffer outside the strait. Total product stocks rose 59% in the week to September 21. Freight still decides who can use them.
Soymeal was the strongest agricultural move. US values rose about $14–20/mt as crushers struggled to secure nearby soybeans.

Crude Oil: The Benchmark Moved Faster Than the Route

The headline crude market changed direction several times.

The Dubai cash premium was assessed at $24.95/b on September 18, $21.44/b on September 21 and $17.92/b on September 22. ICE November Brent settled at $99.25 on September 22, the first front-month close below $100 since September 8. The selling followed reports that US and Iranian officials were talking, including a phased framework for reopening Hormuz that Reuters described on September 24. No agreement had been reached.

Prompt Middle East benchmarks then surged. On September 24, November Dubai and Oman were assessed above $117/b, up more than $7 on the day, and Dated Brent was assessed near $125.52/b. ICE November Brent settled at $106.60. The next session gave part of that spike back: November Dubai fell to about $113.29/b.

The physical signal is the split between those two moves and the freight market.

The week repriced two different risks:

the probability of a political opening, which can move a benchmark within hours;
the availability and cost of a ship on a specific route, which changes much more slowly.

A softer flat price on a headline is a different event from a cheaper delivered barrel.

Hormuz: More Oil Is Moving Through a Narrower Corridor

Visible ship traffic stayed far below a normal pattern, and a large volume of crude still left the region.

In the September 18–21 tracking window, reported crude exits from the Strait of Hormuz were 7.64 million b/d, up more than 40% from 5.4 million b/d in August, as Saudi exports pivoted back toward the strait after Red Sea loadings stopped. Ship-to-ship transfers averaged about 8 million b/d in September to date, also up from 5.4 million b/d in August. US officials described Hormuz crude flows at roughly 60–70% of pre-conflict levels, increasing through an Oman-side corridor.

Crossings did not recover with that volume. Daily transits were reported at 13 ships on September 17 and 14 on September 21, against more than 130 a day before the conflict. A tanker outbound through the strait was struck on September 18. The crew was reported safe. War-risk premiums were described as up more than forty-fold since the end of February, and published freight assessments still exclude that premium.

A diplomatic proposal shows up in crude the same day. A physical normalization requires owners to accept the route, insurers to cut premiums, vessels to reposition, charterers to rebuild programs, and traffic to become repeatable. Government reinsurance and regional cargo pools can keep a hull insurable. They do not add ships.

More oil is leaving the Gulf than in August. It is leaving through fewer transits, more transfers, and a corridor that still carries a crisis premium.

Persian Gulf vs Gulf of Oman: Loading Location Is Part of the Barrel

The clearest measure of that stress is the gap between a cargo loaded inside the Persian Gulf and a cargo loaded from the Gulf of Oman.

Late in the week, the Persian Gulf-to-China 270,000 mt VLCC route remained around w1145, about $238/mt. The Gulf of Oman-to-Far East route was around w800, about $159/mt. The gap is close to $80/mt before war-risk premium and the other costs that sit outside the assessment. The Persian Gulf assessment itself did not move off w1145 during the week. On a delivered basis, freight at that level was described as roughly 40% of the FOB value of several Arab Gulf grades, and about 22–29% of their delivered cost.

A lower FOB differential inside the Gulf can therefore leave a more expensive delivered barrel than a higher-priced cargo already outside the strait.

The comparison that matters is:

FOB differential + loading location + freight + insurance + timing + refinery yield

Dirty Tankers: The Large Ship Paused. The Next Ship Did Not

Dirty freight stopped accelerating uniformly in the second half of the week. It did not become a normal market.

VLCC earnings hit a record near $1.014 million a day on September 18, peaked near $1.019 million on September 21, and eased to about $1.002 million on September 23. The global non-eco VLCC index stayed above $1 million a day. Late-week Persian Gulf-to-China freight was still about 76% higher than a month earlier. West of Suez, fresh VLCC cargoes dried up. West Africa-to-East freight, which had firmed to w535, was assessed at w500 by September 23 as charterers preferred Suezmaxes. Brazil-to-China eased from a record w525 on September 21 to w500 on September 24. The US Gulf Coast-to-China VLCC route fell $1.5 million on September 24, back to $51 million.

The stems that did not go on a VLCC showed up in smaller ships.

Ceyhan-to-Mediterranean Aframax freight jumped about w120 in one session, to w630, on September 21. Route costs on Med-UK Continent, Ceyhan-Med and Sidi Kerir-Med were up about 40% on the week. Black Sea-origin route costs were up about 20%. On September 24, US Gulf Coast-to-UK Continent Aframax freight was assessed at w625, up w95 on the day and the highest since April 8. A Vancouver-to-China Aframax voyage set a new high at $7.7 million on September 18. The Black Sea war-risk area was widened on September 16 to cover almost the whole sea outside third-country territorial waters. Additional war-risk premium on crude shipments was $2.9/b, and it is not inside the freight quote.

The largest ship stopped getting more expensive. The ship that can lift the next stem did not.

Saudi Arabia: Yanbu Is the Swing Factor. Oman Is the Program Already in the Market

The East-West pipeline remained shut after attacks around September 10. No crude has been lifted from Yanbu since September 12. Visible VLCC presence off the port rose to three ships on September 23 and fell to one ship waiting on September 24. A restart has been described as possibly close. It was not confirmed.

The commercial program has already been rewritten around that uncertainty. Aramco was reported to have committed at least 24 million barrels for lifting off the Omani coast across September and October, with most of that volume heard destined for China. ADNOC kept October official prices for several Murban-linked grades at parity and offered an alternative loading at Fujairah. Work on further export routes and overseas storage is the longer version of the same fact: an extra way out of the Gulf now has a measurable value in the crude price.

Europe should not treat a Yanbu restart as an automatic refill. Almost 500,000 b/d of Saudi crude moved to Europe in August, the highest since June 2023. October barrels into Europe were not expected, and restored pipeline volume is more likely to be kept for Asia. If Yanbu does resume, Atlantic replacement demand can ease. Until liftings are confirmed, buyers are competing for other sour barrels.

A cargo off Oman, a cargo inside the Gulf, and a cargo that used to load at Yanbu are three different delivered trades.

Atlantic Basin: Europe Is Short Sour Crude, Not Every Barrel

Replacement demand did not tighten the Atlantic as one pool.

North Sea sour crude carried the security bid. Johan Sverdrup was assessed at $24.21/b over Dated Brent on September 22, above the September 16 high of $23.77/b and above the previous peak of this conflict, $16.75/b in mid-April. Ekofisk was at an $18.15/b premium. Third-decade October Sverdrup was still heard at $22–25/b late in the week, with traders describing the level as close to a peak. The grade's refining margin had already fallen from $46.31/b on September 1 to $20.91/b on September 15. Scarcity and profitability are no longer the same number.

WTI Midland into Rotterdam stayed bid and the premium eased, from Dated plus $18.30 and plus $17.30 early in the week to plus $15.50 for a late-October arrival on September 23.

West African October crude told the other story. A Europe-based trader put unsold volume near 30 million barrels, even while offers for some Nigerian grades were still heard in the mid-teens over Dated. Canadian heavy discounts widened to the weakest levels since late 2023, with WCS Hardisty at $22/b under WTI CMA and Pacific heavy grades at record lows. In the Mediterranean, freight and a steep forward structure erased the arbitrage. A mid-October CPC Blend Suezmax into Augusta was offered down from Dated plus $5.85 to plus $3.55 and was still outstanding.

Europe is short the sour barrel it can run. It is long other Atlantic crude that freight or quality keeps from being a substitute.

China: Lower Runs Can Tighten Products

China is where the expensive delivered barrel is already changing refinery behavior.

Middle East crude imports, including Iranian volumes, were about 4.23 million b/d in January–August, down roughly 33% year on year. Total crude imports fell about 14.6% to 9.68 million b/d. Russia supplied about 30% of August arrivals, and ESPO premiums reached a record of ICE Brent plus $30/b delivered into Shandong.

Independent plants in Shandong have been cutting rates since mid-September. One 800,000 b/d private refinery in East China was reported planning to run at about 50–60% in September after more than 80% in August. State refiners were preparing early-October cuts because cargoes are late. A reduction in China's tariff on US crude was widely expected around a Washington visit on September 23–25. No change had been confirmed in the week's market reports.

The barrels that do arrive from outside the Gulf are clearing as security, not as cheap alternatives. WTI Midland delivered to Yeosu reached a record premium of $34.6/b to front-month Dubai on September 18 and was last assessed near $34/b on September 23. Brazilian Tupi delivered to Qingdao averaged about $27/b over Dubai in September, against about $17/b in August. South Korea extended crude-freight rebates to 100% for September–December, with a stated aim of cutting the Middle East share of crude imports.

The feedback loop runs downstream:

higher replacement cost → weaker refinery margins → lower runs → fewer clean-product exports → tighter supply for the buyer who was counting on those exports

September Chinese clean-product exports were unusually strong. October availability is expected to fall. Lower Chinese crude demand does not automatically loosen the product market.

Clean Tankers: The Product Ship Is Still Getting More Expensive

Clean freight moved the other way from VLCCs.

Arab Gulf-to-Japan LR1 and LR2 freight were assessed at w775 at the start of the week and at w875 on September 24. Loadings inside the Persian Gulf were still indicated well above Gulf of Oman positions, with LR1 inside the Gulf heard near w950. Arab Gulf-to-UK Continent LR2 freight on a 90,000 mt basis reached an all-time high of $156.11/mt. Long-range clean earnings rose to about $218,000 a day on September 23, while VLCC earnings were easing. Medium-range freight rose across the Mediterranean, the Black Sea, the UK Continent and the Americas. In East Asia the MR list was tight enough that charterers were comparing one LR stem with several MR cargoes.

A diesel, jet or naphtha cargo can look workable on the product spread and fail once this freight is inserted.

Clean freight is now doing the job dirty freight did earlier in the disruption: it separates a barrel that exists from a barrel that can be delivered.

Europe Diesel: The Flat Price Swung. The Stock Did Not Recover

CIF Northwest Europe 10 ppm diesel fell from about $1,559/mt on September 18 to about $1,480/mt on September 21, the first assessment below $1,500 since September 9. The Mediterranean cargo fell faster. By September 22 the Med-to-Northwest Europe spread was zero. On September 24 the FOB ARA barge was back at $1,507.25/mt, and the barge crack was near $98.48/b. EU retail diesel averaged 222.64 euro cents a liter in the week to September 21, the highest Commission reading on record.

The inventory picture explains why the flat-price drop did not loosen the physical market.

In the week to September 24, ARA diesel and gasoil stocks were about 1.636 million mt, roughly 25% below a year earlier. Middle East diesel exports to Europe are averaging about 110,000 b/d in September, the lowest since February 2020, against 191,000 b/d in August. US diesel and gasoil arrivals were reported near 1.9 million mt for September, against 2.2 million mt in August and 1.1 million mt in September 2025. That US figure is a mid-month running total. About 660,000 b/d of European refining capacity was offline, and runs are expected to fall by roughly 700,000 b/d from August to October on planned work.

Europe can print an $80/mt drop with crude and still need a long-haul cargo, a clean ship, and an export rule that has not been settled.

Diesel Policy: Two Export Valves Are Under Pressure

Russia tightened the diesel balance from the plant and from the rule.

Strikes were reported at the Moscow refinery and then at Kuybyshev and Ufa. By September 24, market sources described the Moscow, Kuybyshev, Syzran, Ryazan, Saratov and Kirishi plants as fully offline. Officials have said supply can be restored this year. Restart timing that had been discussed for early October is now uncertain. A producer export ban decided on September 14 runs through the end of October. Exports by companies that are not producers are restricted through January 2027. Seaborne diesel and gasoil shipments still rebounded in the week to September 17, so the ban is not a total stop. It closes the normal export valve while capacity is down.

The United States added a second uncertainty.

On September 22 the administration said export restrictions were under consideration. A reported plan for a 90-day ban was then called inaccurate. On September 24 the energy secretary said a complete halt to diesel exports was not the proposal under discussion, and left open a later announcement. US plants are producing about 5.3 million b/d of distillate against domestic demand near 3.6 million b/d. That gap is part of Europe's marginal supply. One analysis of a full ban concluded that Gulf Coast storage could not absorb the surplus for long, and that plants would be more likely to cut runs than to fill tanks. That is a boundary case, not a rule.

The rule did not change this week. The uncertainty is already in forward sales, inventory plans and the willingness to commit a long-haul cargo.

A visible US distillate barrel and a deliverable European barrel are separated by a decision that is still being written.

Rhine: Arrival at Rotterdam Is Not Inland Supply

Water at Kaub was about 22 cm on September 18, about 15 cm on September 21 and about 5 cm late in the week. Forecasts pointed toward roughly 1 cm around September 29.

At these levels the constraint is payload. Barges cannot move a normal volume, the cost per ton rises, and more demand is pushed onto rail and pipeline that are already heavily used. Diesel, heating oil, gasoline components and naphtha into Germany share the same water.

A cargo that has reached ARA has not reached the inland buyer.

Asian Gasoil: The Spread Now Pays for a Westbound Voyage

Asian gasoil structure eased while Europe's diesel crack stayed extreme.

The October-November Singapore gasoil spread, above $11/b in mid-September, was indicated between about $5.30/b and $7.50/b through this week. The FOB Singapore 10 ppm cash differential fell from $3.99/b on September 18 to $3.05/b on September 22, then recovered to $3.51/b on September 23. Onshore Singapore middle-distillate stocks rose 5.39% to 8.68 million barrels in the week to September 16. Into the close of this week those inventories were reported lower.

The spread that sets the trade is the gasoil East-West.

It widened to −$199.82/mt on September 23, from −$162.69/mt the day before. That is the lowest reading since the marker was introduced in 2009. At that level a westbound arbitrage can open even after the clean-freight rally. Cargoes were already reported moving toward Turkey. China's gasoil exports reached 1.33 million mt in the latest monthly data, the highest in 29 months, and October clean exports are expected to fall sharply from September's pace above 4 million mt.

Europe's diesel bid is now wide enough, on a spread basis, to pull Asian barrels west if a clean ship can be fixed at these rates.

Jet Fuel: Stocks Fell Back, and the Regrade Still Favors Diesel

European jet inventories recovered, and then the recovery stalled.

ARA jet and kerosene stocks reached about 543,000 mt around September 18, up almost 20% on the week and still about 49% below a year earlier. By the week to September 24 they were back at roughly 510,000 mt. Imports in the week beginning September 21 dropped to about 643,000 mt, from more than 1.15 million mt the week before. Asia supplied almost all of the reported volume. No Arab Gulf cargoes appeared in the cited flows.

Asia's prompt price reversed inside the same week. The Singapore jet cash differential weakened to a discount of about $2/b, the weakest since May 2020, and by September 24 had flipped to about +$1.48/b, the first premium after eight negative sessions. The jet-versus-gasoil regrade stayed negative, around $4.5–4.9/b in favor of gasoil, wider than the July and August averages. India's August aviation-fuel exports were a six-month low. China's August jet exports were very large, and October clean exports are expected to fall.

The premium returned in Asia. The refinery is still being paid more to make diesel, and the import flow that rebuilt European stocks has already slowed.

Naphtha and Gasoline: Spare Barrels Are in the Wrong Place

European naphtha stayed structurally low without a simple bullish price signal.

ARA stocks recovered to roughly 302,000 mt late in the week and were still more than 40% below a year earlier. Petrochemical demand remained weak. The Rhine, not the cracker, decides how much of the ARA barrel is useful inland. South Korea, Asia's largest naphtha importer, continued to diversify away from Middle East supply: January–August imports were down 24% year on year, US arrivals rose more than threefold, and buyers were looking at Latin America.

Gasoline split by location.

Northwest European barges firmed on September 22 even while crude was still falling. West African premiums weakened late in the week. Dangote ran at about 105% of capacity in August, up from 71% in July, and gasoline output rose more than 50% on the month. In September the refinery loaded no coastal gasoline cargoes and concentrated on truck supply. Nigeria issued fourth-quarter import licenses on September 18. The coast is not yet an export source for the region. It is a plant that ran hard in August and did not load seaborne gasoline in September, while import demand was licensed again. Indonesia was heard seeking 13.8 million barrels of 90 RON, plus at least 1 million barrels of 92 RON, for November–December. China's October gasoline exports were discussed in a range of 300,000–600,000 mt.

Length in one hub is not a spare barrel for the coast, the specification, or the inland plant that cannot be reached.

Fuel Oil: The Europe-to-Asia Window Reopened

Fuel oil stayed split by basin.

Singapore 380 CST HSFO cash premiums eased to about $39/mt by September 21, roughly a quarter below the prior week's level. The crack against prompt Brent firmed from about −$4.44/b on September 18 to a small positive by September 24. The prompt swap spread stayed steep, near $35–38/mt. Traders pointed to missing Russian inflows. No Saudi fuel-oil shipments were reported into the Asian market. Singapore heavy-distillate stocks had drawn 1% to a three-week low of 20.1 million barrels in the week to September 16.

Low-sulfur fuel oil moved the other way. The Singapore-versus-Rotterdam 0.5% spread widened to $142/mt on September 22, the widest since March 31, and the Europe-to-Asia arbitrage was described as open. In Northwest Europe, high-sulfur looked balanced and very-low-sulfur tighter, because distillate cracks keep pulling blendstocks out of the bunker pool.

European residue can cross when the spread pays the ship. Asian high-sulfur, short of Russian and Saudi inflows, cannot wait for that crossing.

Fujairah: The Buffer Outside the Strait Was Rebuilt

Fujairah inventories reversed the prior week's draw, and the rebuild was not a fuel-oil story alone.

In the week to September 21, total product stocks rose 59% to a five-month high. Heavy distillates and residues rose 97% to 5.6 million barrels. Middle distillates rose 23% to 2.60 million barrels, a six-month high. Light distillates also increased.

Fujairah sits outside the strait. It is one of the few loading points that avoids the full inside-Gulf freight premium. A larger stock there is a real buffer. VLCC and long-range freight from the Gulf of Oman is still historically expensive, and ship-to-ship delays at the anchorage have been holding ships for days.

Volume at Fujairah becomes supply for another region only after freight, insurance and a free ship are added back in.

Libya: A Nearby Crude Source Slowed Before the Price Did

Libyan exports added a separate supply risk late in the week.

Crude exports were heading toward roughly 600,000 b/d for the week beginning September 21, compared with about 1.48 million b/d the previous week. Sharara exports dropped to zero as disruptions hit the field and the infrastructure around it.

The Mediterranean price in the supplied reports had not yet matched that volume loss. The timing still matters. Europe is already short flexible Middle East sour supply, paying extreme freight, and running into refinery maintenance. A sustained Libyan outage would remove another nearby barrel from that system.

Grains and Protein: Soymeal Tightness Is the Agricultural Exception

Oil this week was a transport story. The grain complex was not.

US soymeal rose about $14–20/mt as crushers struggled to source spot and nearby soybeans against strong demand. US soybeans increased around $5/mt. Corn was broadly unchanged. US winter wheat weakened by about $5–8/mt, and spring wheat was little changed.

Russian export taxation shifted for the period effective September 30. The wheat duty fell to RUB 640.3/mt. Barley remained at zero. The corn duty increased to RUB 220.6/mt, up roughly 39%.

Dry-bulk freight was comparatively stable. The Baltic Dry Index rose modestly to 3,426. The Panamax Index increased by 156 points to 2,407. Changes on most major grain routes were limited.

The protein signal this week is nearby US soybean availability, not a freight shortage.

Key Physical Market Signals

Crude: the Dubai prompt premium fell about $12/b into September 22, November Dubai jumped above $117 on September 24, and the next session gave part of that back, to about $113.29.
Hormuz: crude exits and ship-to-ship transfers are well above August, while visible crossings remain a small fraction of pre-conflict traffic.
Persian Gulf freight: w1145 against about w800 for Gulf of Oman is a location premium near $80/mt, before war-risk costs.
VLCC: earnings peaked near $1.019 million a day and paused above $1 million. Absolute freight is still high enough to split stems.
Aframax: Mediterranean, UK Continent and US Gulf freight absorbed the barrels VLCCs did not lift. US Gulf-UK Continent reached w625.
Yanbu: liftings are unconfirmed since September 12. The working alternative is the Omani coast, including at least 24 million barrels already reported.
North Sea sour: Johan Sverdrup at $24.21/b over Dated is a security premium. The refining margin on the grade is already much lower than at the start of the month.
Atlantic length: October West African crude is long, and Canadian heavy discounts are the widest since late 2023.
China: Middle East arrivals are down sharply, runs are being cut, and replacement crude is clearing at record delivered premiums.
Clean freight: Arab Gulf-UK Continent LR2 freight set a high at $156.11/mt. Arab Gulf-Japan LR freight rose to w875.
Diesel: ARA stocks near 1.636 million mt are about 25% below last year. Middle East inflows are the lowest since February 2020.
Policy: Russia's producer export ban runs through October. The US ban was set aside as a blanket measure and remains an open option.
Rhine: about 5 cm at Kaub, with forecasts near 1 cm around September 29.
Asian gasoil: the East-West spread at −$199.82/mt is wide enough to pull barrels toward Europe and the Mediterranean.
Jet: ARA stocks fell back to 510,000 mt. Singapore cash returned to a premium, and the regrade still favors gasoil.
Fujairah: a 59% weekly build restores a buffer outside the strait. Freight still decides who can use it.
Fuel oil: Asian high-sulfur tightened on missing Russian and Saudi flows. The Europe-to-Asia low-sulfur window reopened at $142/mt.
Libya: exports slowed sharply, led by Sharara, before the Mediterranean price fully reflected it.
Gasoline: Dangote loaded no coastal cargoes in September, and Nigeria reissued import licenses.
Soymeal: nearby US soybean availability pushed values up $14–20/mt. Grain freight was comparatively stable.

What to Watch Next

1. Hormuz negotiations and actual vessel traffic

Diplomatic headlines will keep moving crude the same day. The physical test is whether commercial crossings rise from roughly 14 ships a day, or whether volume stays in the Oman-side corridor and in ship-to-ship transfer.

2. Persian Gulf versus Gulf of Oman freight

A gap near $80/mt is the live measure of route risk. A sustained narrowing would be the first sign that loading inside the Gulf is becoming a normal trade again.

3. Yanbu loadings against the Oman program

Three VLCCs off the port, then one, is not a restart. Confirmed liftings would change Saudi flexibility. Until then, the Omani-coast barrels already reported are the working program, and they are pointed mainly at Asia.

4. Whether the VLCC ceiling spreads or fades

Freight can slip on VLCCs and stay extreme on Suezmax and Aframax if charterers keep splitting stems. US Gulf-UK Continent Aframax at w625 is the level that has to give way before the pause becomes a correction.

5. Chinese refinery runs and October product exports

Lower crude availability is already in the run rate. October gasoil, jet and gasoline exports are the swing supply for Asia, and for any westbound arbitrage.

6. The gasoil East-West spread against clean freight

At about −$200/mt, Asian gasoil can move west on paper. The test is whether LR freight near $156/mt to the UK Continent still leaves the cargo workable, and whether Europe receives those barrels before ARA stocks need them.

7. The wording of any US diesel decision

A blanket ban has been publicly set aside. A narrower restriction, a timing signal, or another quiet week will each change how Europe counts US barrels for the fourth quarter.

8. Russian refinery restarts against the diesel ban

The producer export ban runs to the end of October. A restart before then still leaves the export valve closed. A longer outage would tighten Mediterranean and European replacement further.

9. Rhine water at Kaub

Forecasts point toward about 1 cm around September 29. A recovery would reopen barge economics. Several more days at a few centimeters would keep inland premiums disconnected from ARA.

10. Libya

A sustained reduction in Sharara and the associated export flows would remove nearby sour supply from a Mediterranean market that is already paying up for freight and for North Sea replacements.

11. Asian jet and the next Singapore stock reading

The return to a jet premium, and the reported late-week draw in Singapore middle distillates, need to be set against October Chinese exports. The week-to-September 16 build, to 8.68 million barrels, is the baseline.

12. US soymeal availability

The rally is coming from crusher access to spot and nearby soybeans. That access, not dry-bulk freight, decides whether the move holds.

The Bottom Line

The week separated a fast financial repricing from a slow physical one.

Talks were enough to take Brent through $100, cut the Dubai prompt premium by about $12/b, put it back above $117, and then give part of that spike back on September 25. Ships did not make the same round trip. Persian Gulf freight stayed about $80/mt above Gulf of Oman freight. Clean long-range rates and Aframax rates rose through the VLCC pause. European diesel stocks remained about a quarter below last year. The Rhine fell toward a level that stops a normal barge. China cut runs because the delivered barrel was late and expensive.

The useful stack is:

physical availability + loading location + vessel class + route access + insurance + ocean freight + inland logistics + export permission = delivered value

That is why the week's contradictions can all be true at once.

Crude prices can fall while freight stays high. Fujairah stocks can rise while replacement costs stay elevated. Chinese crude demand can weaken while Asian product supply risk increases. European diesel flat prices can drop $80/mt while the stock is still tight and the crack is near a record. An Asian gasoil barrel can be cheap enough, at −$200/mt on the East-West spread, and still need a ship at $156/mt. A Russian or US distillate barrel can exist and still fail the export rule.

The question is which cargo can be loaded, insured, shipped and moved inland — and is still allowed to leave the country that produced it.
