Physical Markets Weekly: Atlantic Freight Shock, Strategic Stock Releases and Product Supply Risk

Physical commodity markets ended the week with a major change in the geography of the logistics shock.

For much of September, the central constraint was the cost of moving crude and products from inside the Persian Gulf. That problem remains unresolved. Persian Gulf-to-Asia freight still carries a large premium over Gulf of Oman loading positions, vessel traffic through the Strait of Hormuz remains severely disrupted, and further attacks on commercial shipping have prevented owners and charterers from treating the route as normalized.

But the freight shock is no longer confined to the Gulf.

During the week, tanker tightness spread aggressively into West Africa, the Black Sea and the broader Atlantic Basin. West Africa-to-Europe Suezmax freight approximately doubled in only a few sessions, Black Sea-to-Mediterranean Suezmax rates surged, and Brazil-to-China VLCC freight reached a record. The result was a direct repricing of physical crude: African FOB differentials weakened sharply because higher freight absorbed the value of the barrel before it reached the refinery.

At the same time, governments began using strategic inventories to attack the product-price problem from another direction. The G7 agreed to a coordinated release of 100 million barrels of oil and diesel reserves, while the US Department of Energy offered up to 40 million barrels of SPR crude for November-December delivery.

That immediately hit European middle-distillate prices.

But it did not resolve the underlying physical constraints.

ARA jet inventories fell to their lowest level since 2020, naphtha stocks reached a 34-month low, Russian diesel exports remained restricted, Chinese October product exports became uncertain, and Rhine water around Kaub fell effectively to zero.

The market therefore ended the week with a new distinction:

strategic inventory can reduce the price of the prompt barrel, but it cannot immediately create tanker capacity, restore export flows or move product through a blocked inland logistics system.

Agricultural markets moved in the opposite direction. US corn, soybean, soymeal and winter wheat prices all fell as harvest pressure, larger corn inventories and improved soymeal availability outweighed supply concerns.

Market at a Glance

• The tanker shock has spread west. West Africa-to-Europe and Black Sea-to-Mediterranean Suezmax freight almost doubled during the week.
• Persian Gulf route risk remains embedded in crude freight. PG-to-China VLCC freight ended around w1135 compared with roughly w750–800 for Gulf of Oman positions.
• Yanbu provided meaningful route diversification. Saudi Red Sea loadings rebounded to roughly 2.8 million b/d after the earlier East-West Pipeline disruption.
• Strategic stock releases changed product pricing faster than physical supply. The G7 reserve announcement triggered a sharp selloff in European gasoil and jet.
• European jet remains physically tight. ARA stocks fell 14.3% week on week to 437,000 mt, the lowest level since 2020.
• ARA diesel stocks rose for the wrong reason. Inventories increased 11% to 1.816 million mt, but the build was attributed partly to Rhine disruption preventing product from moving inland.
• Rhine logistics reached an extreme. Kaub printed around zero late in the week, sharply limiting barge economics.
• China has become the largest near-term product-supply uncertainty. Golden Week customs timing, delayed quotas and reported cargo cancellations reduced visibility for October gasoline, gasoil and jet exports.
• Clean tanker freight remains historically strong, but the East-of-Suez LR market may be approaching a peak.
• Russia continues to remove diesel from the export market. The producer export ban was extended through October.
• Urea weakened despite continuing Gulf logistics constraints. Additional Chinese export allocations shifted the balance toward greater supply.
• Agricultural markets were broadly softer. Soymeal recorded the largest decline, falling roughly $24–30/mt during the week.

Crude Oil: Physical Supply Is Improving Faster Than Route Security

The Middle East crude system showed two very different developments this week.

Physical export availability improved.

Saudi Arabia resumed substantial Red Sea loadings from Yanbu after the disruption to the East-West Pipeline. The supplied market data showed loadings increasing to approximately 2.8 million b/d for the week beginning September 28, compared with only 77,000 b/d the previous week.

UAE sellers also shifted substantial volumes through STS locations around Fujairah and Sohar. A reported UAE tender placed at least 11 million barrels, including Upper Zakum and Das Blend, with buyers across China, India, Singapore, Japan and South Korea.

Those flows show that producers and buyers are adapting.

But adaptation is not normalization.

Middle East crude exports through Hormuz, Fujairah and the Red Sea averaged roughly 13 million b/d during September 1–28. That was significantly above August's 10.7 million b/d but still around 36% below the prewar February level of 20.2 million b/d.

The physical system is therefore restoring capacity through alternative routing rather than returning to its previous structure.

That difference matters.

The market has recovered some volume, but not the original flexibility of the supply chain.

Hormuz: Volume Recovery Has Not Removed Route Risk

Strait of Hormuz traffic remained unstable throughout the week.

Transits fell to 13 vessels on September 27, increased modestly afterward, and then collapsed to only 11 vessels on October 1, the lowest level in around six weeks. Multiple incidents involving projectiles striking commercial ships were also reported during the period.

The critical point is that crude can move through a constrained system without that system becoming normal.

Cargoes can use:

• STS transfers;
• reduced AIS visibility;
• alternative ports;
• Gulf of Oman loading;
• Red Sea routing;
• and higher-risk conventional transits.

Those mechanisms increase effective supply.

They do not restore normal vessel willingness, insurance economics or chartering flexibility.

This is why the physical market continues to assign a substantial premium to crude loading inside the Persian Gulf.

Persian Gulf vs Gulf of Oman: The Location Premium Survived the Week

The most persistent East-of-Suez freight signal was the gap between Persian Gulf and Gulf of Oman loadings.

At the start of the week, PG-to-China VLCC freight was around w1150, while Gulf of Oman-to-Far East was around w795.

By October 2:

• PG-to-China 270,000 mt VLCC freight was approximately w1135;
• Gulf of Oman-to-Far East was approximately w750, or $148.80/mt;
• inside-Gulf indications remained around w1100–1145.

The headline PG freight assessment therefore barely corrected despite the improvement in Saudi Red Sea exports and greater use of Fujairah/Sohar STS.

That is commercially important.

The market is distinguishing between:

Middle East crude availability

and

Middle East crude availability from a commercially acceptable loading location.

The second remains much scarcer.

Dirty Tankers: The Freight Shock Migrated Into the Atlantic

The largest change of the week occurred outside the Persian Gulf.

On September 28, benchmark West Africa-to-UK Continent Suezmax freight was around w440.

By October 1 it had reached w745.

One day later it was assessed around w875.

In dollar terms, West Africa-to-Europe Suezmax freight increased from approximately $75.72/mt on September 28 to $150.59/mt on October 2.

This is no longer a marginal logistics adjustment.

It directly changes the market value of African crude.

The same effect appeared elsewhere:

• WAF-to-East VLCC freight rose to w650;
• Brazil-to-China reached a record w625;
• Black Sea-to-Mediterranean 135,000 mt Suezmax freight reached w967.5.

The freight crisis has therefore entered a second stage.

In September, the problem was primarily:

how expensive is it to leave the Gulf?

The question now is increasingly:

where can a replacement vessel be found anywhere in the system?

West African Crude: Freight Is Destroying FOB Value

The effect on West African crude was immediate.

As freight increased, sellers had to reduce crude differentials to preserve delivered competitiveness.

By October 2:

• Congolese Djeno was offered at around a $15.35/b discount to Dated Brent;
• Angolan Hungo was offered at around a $9.90/b discount.

This is an important example of the difference between FOB weakness and genuine supply abundance.

The barrel itself has not necessarily become intrinsically less valuable.

The transport cost between origin and refinery has increased so sharply that the FOB price must absorb the difference.

The physical equation becomes:

delivered refinery value – freight – route cost = acceptable FOB crude value

When freight doubles, the crude differential has to move unless refinery margins expand by the same amount.

That is why extreme freight can produce apparently bearish FOB crude signals inside an otherwise tight global supply system.

Black Sea and Mediterranean: Tonnage Scarcity Is Now Regional

The same mechanism appeared in the Black Sea.

Black Sea-to-Mediterranean Suezmax freight was around w500 at the beginning of the week. By October 2 it had reached approximately w967.5.

Part of the move reflects cargo demand.

But another part reflects vessel positioning.

When Atlantic Suezmax earnings rise sharply, owners have less reason to commit vessels cheaply into competing basins. The stronger Atlantic market effectively pulls available capacity away from Black Sea and Mediterranean charterers.

This is the same transmission mechanism previously seen when VLCC scarcity pushed stems into Suezmaxes.

The freight shock moves through vessel classes and regions because the fleets compete for the same marginal tonnage.

Clean Tankers: Extremely Strong, but the First Signs of Supply Response Are Appearing

Clean freight strengthened further during most of the week.

The global clean tanker index reached a record above $122,000/day on October 1, while North Asian MR rates climbed toward w560–570. Round-trip Singapore-to-Australia MR earnings were estimated around $75,000/day, compared with roughly $32,000/day four months earlier.

Arab Gulf clean freight also remained high.

By October 2, Arab Gulf-to-Japan LR1 and LR2 assessments were both around w910, with inside-Persian-Gulf loadings indicated near w950.

But the clean market finally showed evidence of a possible supply response.

Expected LR1 availability over the following three weeks increased to around 38 vessels, up from roughly 30 one week earlier.

That does not make freight cheap.

It means extreme earnings are beginning to attract tonnage.

The market may therefore be approaching the point where repositioning starts correcting scarcity, at least on the larger clean segments.

MR markets remain more fragmented and regional.

Europe Diesel: Strategic Stocks Hit Price, Not the Physical Constraint

European diesel experienced an extraordinary end to the week.

The G7 announcement of a coordinated 100 million barrel emergency stock release, including an accelerated release of diesel, immediately changed front-end positioning. Reuters reported that oil prices began falling following the decision.

On October 2, front-month ICE LSGO fell $95.75/mt to $1,355.50/mt, its lowest level since August 28.

Jet CIF Northwest Europe fell more than $100/mt on the same day.

But the physical data do not show a loose European middle-distillate system.

ARA diesel and gasoil inventories increased by around 180,000 mt to 1.816 million mt, an 11% weekly build.

Yet stocks were still approximately 18% below the previous year. More importantly, market participants attributed part of the build to the inability to move product inland because of extremely low Rhine water.

That changes the interpretation completely.

An inventory increase caused by a logistics blockage is not equivalent to an inventory increase caused by weak consumption or surplus supply.

The barrels exist in ARA.

Their ability to reach inland demand has deteriorated.

Stocks rose because distribution weakened.

Rhine Logistics: ARA Inventory Is No Longer the Same as Inland Supply

The Rhine moved from a severe constraint to an extreme constraint.

Kaub was already around 2 cm on September 28.

By October 1 readings were around or below zero, and on October 2 Kaub printed approximately 0 cm in the supplied market data.

Traders reported that normal loading in ARA and Germany had become extremely difficult and inland inventories were being depleted.

This creates a physical segmentation inside Europe.

ARA may show more diesel.

Germany can simultaneously experience less accessible diesel.

The same problem affects:

• naphtha;
• heating oil;
• gasoline components;
• petrochemical feedstocks;
• and fertilizers.

This is why regional inventory data require a logistics adjustment.

A barrel in Rotterdam is not necessarily a barrel available in inland Germany.

Jet Fuel: Europe and Asia Tightened at the Same Time

Jet produced one of the clearest physical signals of the week.

ARA jet and kerosene inventories fell 14.3% week on week to 437,000 mt, the lowest level since 2020.

That decline occurred while Asian replacement supply became less predictable.

China entered the week with expectations for substantial October clean-product exports, but the late issuance of export quotas immediately before the National Day holiday disrupted customs clearance. Market sources subsequently reported that some October-loading jet cargoes had been canceled or suspended.

Asian jet pricing reacted rapidly.

The FOB Singapore jet/kero cash differential reached approximately +$5.41/b to MOPS by the October 1 Asian close, a five-month high.

The significance goes beyond the Asian market.

Europe has increasingly relied on long-haul replacement jet from Asia.

If Asian exporters become less reliable at the same time European stocks are falling and clean tanker freight is elevated, Europe must increase its delivered premium to attract the next marginal cargo.

China: Export Optionality Has Become More Important Than Refinery Capacity

China's role in the product market changed noticeably during the week.

Earlier expectations centered on how much gasoil, gasoline and jet Chinese refineries would export in October.

By the end of the week, the larger question was whether scheduled cargoes could load at all.

The third product-export quota batch was released late on September 30, leaving only a very short customs window before the October 1–7 Golden Week closure. One source characterized the subsequent slowdown primarily as a customs bottleneck, while another reported a broader halt on exports outside Hong Kong and Macau. The supplied reports explicitly note the differing characterizations.

The distinction should not be ignored.

There is not yet one clean explanation for the disruption.

But the physical consequence is similar in the near term:

fewer reliably deliverable October cargoes.

That is what the market is pricing.

Russia: Another Major Diesel Supply Pool Remains Restricted

Russian product availability remains another constraint on global replacement supply.

Russia extended its diesel export restrictions through the end of October, with Reuters confirming the continuation of the producer export ban.

The supplied market reports also described continuing refinery disruptions and restrictions on other fuels.

That matters most for Europe because the replacement chain is already stretched.

Europe is simultaneously exposed to:

• restricted Russian supply;
• uncertain Chinese exports;
• expensive clean freight;
• low jet inventories;
• Rhine constraints;
• and dependence on strategic inventories to suppress immediate price pressure.

The G7 release adds supply.

It does not remove the structural dependence on replacement flows.

Naphtha: Inland Constraints Meet Low Inventory

European naphtha inventories deteriorated further.

ARA stocks fell 12.9% week on week to approximately 263,000 mt, the lowest level since January 2024.

That would already be a tight inventory signal.

The Rhine makes it more important.

Petrochemical demand may be weak enough to limit outright price pressure, but the logistics system has less physical buffer if consumption unexpectedly increases or replacement arrivals are delayed.

Naphtha therefore illustrates the broader theme of the week:

weak end-use economics do not eliminate supply-chain vulnerability when inventories and transport capacity are both low.

Fuel Oil: Regional Separation Remains Wide

Fuel oil markets remained fragmented.

Asian HSFO continued to show strong prompt structure, while Singapore low-sulfur fuel oil retained a substantial premium over Northwest Europe.

The Singapore 0.5% sulfur fuel oil spread versus Rotterdam reached around $152/mt late in September, approximately 17% wider than in mid-September.

At the same time, Singapore heavy-distillate inventories fell 5.3% week on week to a six-week low of approximately 18.7 million barrels, while Fujairah heavy distillate and residue stocks also registered a large weekly decline.

That keeps the Europe-to-Asia arbitrage relevant.

But again, an open paper spread only matters if freight leaves enough margin for the physical cargo to move.

Urea: Chinese Supply Is Finally Outweighing Part of the Freight Shock

The fertilizer market moved differently from oil.

At the beginning of the week, activity was limited as buyers waited for the next Indian tender. Chinese prilled urea values were firm and Egypt granular business was still around the mid-$530s/mt FOB.

The balance changed after China issued another round of export allocations.

Market expectations placed additional availability around 1.5–2.0 million mt, on top of earlier allocations. By the second half of the week, prices had weakened across several regions:

• Egypt granular urea: approximately $510–525/mt FOB;
• Middle East: $440–450/mt FOB;
• Nigeria: $460–470/mt FOB;
• Brazil: $465–485/mt CFR;
• Chinese granular: around $435–440/mt FOB.

This is a genuine supply-side change.

But the Gulf logistics problem remains.

The supplied fertilizer data indicate that only eight apparently urea-loaded vessels exited the Middle East Gulf during September, six carrying Saudi material. That represented only a fraction of the region's normal prewar export pace.

The fertilizer market is therefore balancing two opposite forces:

more Chinese export supply versus constrained Middle East route capacity.

At present, Chinese supply is winning the price argument.

India Urea: The October 7 Tender Is the Next Global Allocation Event

India now becomes the main test.

IPL is seeking approximately 1.7 million mt of urea, with the tender scheduled to close October 7.

This matters because India can rapidly absorb a large part of newly available Chinese tonnage.

If Chinese product dominates the tender, it validates the assumption that the latest export allocations represent genuine global supply relief.

If the tender clears at higher prices or requires larger participation from other origins, the market will have evidence that nominal Chinese availability is less accessible than current prices imply.

The key issue is therefore no longer:

how much urea can China export?

It is:

how much Chinese urea can actually clear into the largest import programs at current freight-adjusted prices?

Grains and Oilseeds: Harvest Pressure Returned as the Dominant Driver

Agricultural markets were broadly weaker.

The October 3 weekly grain report showed:

• US corn down approximately $12/mt;
• US soybeans down $12–15/mt;
• US soymeal down $24–30/mt;
• US winter wheat down $8–10/mt;
• US spring wheat unchanged.

Corn weakened after USDA ending stocks were reported sharply higher, while harvest pressure added to selling as storage filled and growers moved inventory.

Soybeans also came under harvest pressure, with the absence of large new Chinese orders adding to weakness.

Soymeal recorded the largest move.

The report indicates that supply had finally caught up with demand after the previous period of nearby tightness, removing the scarcity premium that had supported the market.

This is a very different mechanism from the energy complex.

Energy remains dominated by constrained transportation and replacement supply.

US agriculture is being repriced by seasonal physical availability.

Wheat: Black Sea Supply Is Still Pressuring the Global Market

US winter wheat weakened even though Black Sea logistics remain difficult.

The important point is that enough Black Sea wheat is still reaching the export market to keep international competition intense.

The report notes that Romanian and Bulgarian wheat captured significant tender business while US wheat remained comparatively uncompetitive.

Russian export duties effective September 30 were:

• wheat: RUB 640.3/mt;
• barley: zero;
• corn: RUB 220.6/mt.

This creates an unusual contrast with oil.

Black Sea tanker freight is exploding.

Bulk grain freight remains comparatively manageable, particularly for non-Russian origins.

The same geography can therefore have very different logistics economics depending on vessel segment and cargo type.

Dry Bulk: Grain Freight Is Moving in the Opposite Direction to Tankers

Dry-bulk freight softened during the week.

The Baltic Dry Index fell 278 points to 3,148, while:

• the Capesize Index fell 742 points to 5,042;
• the Panamax Index declined 35 points to 2,372;
• the Supramax Index was essentially stable.

Most major grain routes were steady or only modestly lower.

Brazil-to-China grain freight fell around $2/mt, while several US Pacific Northwest routes declined around $1/mt.

This divergence is commercially important.

There is no single "freight market."

Crude tankers, clean tankers and dry bulk currently show completely different scarcity structures.

For agricultural traders, ocean freight remains an important delivered-cost component.

For oil traders, freight has become one of the primary price-setting mechanisms.

Key Physical Market Signals

• Hormuz: traffic remains severely disrupted despite improving Middle East export volumes.
• Saudi Arabia: resumed Yanbu loadings restore part of the system's route redundancy.
• Persian Gulf: inside-Gulf crude freight remains substantially above Gulf of Oman loading economics.
• Atlantic dirty freight: the strongest tightening of the week, with West African and Black Sea Suezmax rates surging.
• West African crude: FOB differentials are being forced lower by freight rather than simple oversupply.
• Brazil: Brazil-to-China VLCC freight reached a record.
• Clean tankers: earnings remain exceptionally high, although growing LR availability suggests the first potential easing.
• Europe diesel: strategic stock releases caused a large front-end price correction, but physical supply remains structurally constrained.
• Europe jet: inventories fell to their lowest level since 2020.
• Rhine: near-zero water levels are preventing ARA stocks from functioning normally as inland supply.
• Naphtha: ARA inventories reached a 34-month low.
• China products: export timing and cargo cancellations have become major swing factors for Asian jet and gasoil.
• Russia: diesel export restrictions continue to remove a major replacement source.
• Fuel oil: East-West price separation remains large and Asian heavy-product inventories are tightening.
• Urea: additional Chinese export allocation is pressuring international prices despite weak Gulf logistics.
• Corn: larger inventories and harvest selling are weighing heavily on prices.
• Soymeal: supply has caught up with demand, producing the largest weekly agricultural decline.
• Wheat: Romanian, Bulgarian and continuing Black Sea supply are keeping pressure on international prices.
• Dry bulk: weaker, in sharp contrast with tanker freight.

What to Watch Next

1. Actual Hormuz vessel traffic

Headlines are less important than repeatable commercial transit. A sustained rise in normal VLCC, product tanker and gas-carrier traffic would be the strongest sign that route risk is genuinely falling.

2. Persian Gulf versus Gulf of Oman freight

The spread remains one of the cleanest indicators of Middle East execution risk. A persistent narrowing would signal normalization more clearly than crude flat price.

3. West African Suezmax freight

The market needs to determine whether this week's surge represents a temporary tonnage squeeze or a new Atlantic freight regime.

4. Black Sea vessel availability

If Atlantic earnings continue attracting tonnage away, Black Sea and Mediterranean crude freight could remain structurally elevated even without additional regional disruption.

5. G7 strategic inventory flows

The announcement has already affected prices. The next issue is how quickly physical diesel and crude actually reach the market and which regions receive the barrels.

6. ARA diesel versus inland German availability

An ARA stock build should not be interpreted as bearish while Rhine logistics remain severely impaired.

7. Rhine water levels

Even a modest recovery could materially increase barge payloads. Continued near-zero conditions would preserve the disconnect between coastal and inland supply.

8. Chinese product exports after Golden Week

The market needs confirmation of which delayed or canceled gasoline, gasoil and jet cargoes actually return to the loading program.

9. Asian jet pricing

The Singapore jet cash premium has repriced sharply. Sustained strength would confirm that the export disruption is becoming a real regional supply constraint rather than a short holiday distortion.

10. Russian refinery and export policy

Any extension of refinery outages or export restrictions increases the replacement burden on the US, Middle East and Asia.

11. India IPL urea tender — October 7

The 1.7 million mt tender will test whether new Chinese export allocation is sufficient to keep global urea prices under pressure.

12. US harvest progress

Corn and soybean harvest pressure is currently dominating agricultural markets. The speed of harvest, storage pressure and new Chinese soybean demand will determine whether the decline continues.

13. Black Sea wheat competitiveness

US wheat remains uncompetitive in several tenders. Romanian, Bulgarian, Russian and Ukrainian export availability will determine whether international wheat values can stabilize.

The Bottom Line

The physical commodity system is becoming more fragmented, not less.

Middle East export volumes are recovering.

Saudi Arabia has restarted substantial Red Sea loadings.

UAE barrels are moving through alternative STS structures.

Strategic inventories are entering the market.

Chinese fertilizer exports are increasing.

Those are all signs of supply adaptation.

But the logistics system is simultaneously becoming more stressed.

Persian Gulf freight remains extreme.

West African and Black Sea tanker rates have surged.

European inland transport is severely constrained by the Rhine.

Chinese product-export availability has become uncertain.

Russian diesel remains restricted.

Jet inventories are falling.

That is why the central market equation is changing again.

In September, the dominant equation was:

commodity availability + route access + freight = delivered value

This week added another layer:

commodity availability + route access + vessel scarcity + policy-driven inventory + regional distribution capacity = usable supply

The distinction between available supply and usable supply is increasingly important.

The G7 can release diesel.

But that diesel must still be in the correct geography.

ARA can build inventories.

But those inventories must still move inland.

West Africa can offer crude.

But the crude must still survive a $150/mt Suezmax freight bill.

China can issue export quotas.

But the cargo must still clear customs and load.

Middle East producers can have urea ready.

But the vessel still has to leave the Gulf.

That is the physical-market signal of the week:

the world is finding additional commodity supply faster than it is restoring the logistics capacity required to move that supply efficiently.

Until that changes, headline commodity prices can fall sharply without producing an equivalent decline in delivered replacement costs.
