Delivered Crude Hits Spring Highs as JPMorgan Flags Tanker Crunch

Delivered crude prices have climbed back to their spring peaks and European refining margins have slipped below zero again, JPMorgan said in a research note dated October 9. The bank attributes the strain to shipping capacity rather than a shortage of crude, a reversal from April, when the squeeze came from the barrel itself. Middle East flows through the Strait of Hormuz rose from roughly 7.5 million barrels per day across July and August to about 12 million in September. By that month, more than four in five of the world's very large crude carriers were in active service.

Context — Why Delivered Crude Is Repricing Now

The April precedent matters because it shows how quickly a freight-led squeeze can feed into what refiners actually pay. JPMorgan's note draws the distinction directly: this episode is about the cost and difficulty of moving oil, not about crude being unavailable. That changes who absorbs the pain and where the marginal price is set.

A VLCC, the largest tanker class, carries around 2 million barrels. When more than four in five of them are working, spare capacity is thin enough that small disruptions to voyage length translate into large swings in effective supply. The bank's framing is that the market has moved from a regional VLCC shortage to a broad tightening across the global tanker fleet.

The macro backdrop compounds it. European refining margins have turned negative again, which raises the risk that refiners cut runs. Run cuts would trim crude demand and could cap benchmark futures even while delivered costs stay elevated. That divergence is the core tension in the note.

Sanctions add a structural layer. Around 125 Iranian VLCCs, equal to roughly 13% of the global fleet, are effectively shut out of the mainstream market by US measures, with many anchored or drifting in the Gulf or off Sri Lanka and Malaysia. Those vessels exist but do not clear cargoes for mainstream buyers.

The catalyst chain runs from September export volumes through Hormuz, into fleet utilisation, then into voyage economics. JPMorgan's conclusion is that more crude alone would not ease the strain: additional exports without additional ships could deepen it.

Data — What the Tanker Numbers Show

The scale of the reallocation is the story. JPMorgan estimates that moving Middle Eastern crude, excluding Iran, now requires an extra 35 VLCCs, 13 mid-sized Suezmaxes and 10 smaller Aframaxes compared with the 2025 average. As the region absorbs more of the fleet, VLCC employment elsewhere has fallen by 16 vessels.

Atlantic Basin producers are adapting by switching to smaller ships. One VLCC cargo is roughly equivalent to two Suezmaxes or three Aframaxes. Outside the Middle East, Aframax employment is up by about 140 vessels, or 23%, on the 2025 average, while Suezmax employment has risen by around 50 ships, or 11%.

Tanker class	Change vs 2025 average	Where
VLCC	+35 vessels required	Middle East ex-Iran
VLCC	-16 vessels	Outside Middle East
Suezmax	+13 vessels required	Middle East ex-Iran
Suezmax	+50 vessels, +11%	Outside Middle East
Aframax	+10 vessels required	Middle East ex-Iran
Aframax	+140 vessels, +23%	Outside Middle East

The productivity drag is separate from the ship count. Ship-to-ship transfers, where cargo moves between tankers at sea, can occupy a vessel for up to 10 days. Longer risk-avoiding routes extend voyages further. Both reduce the number of cargoes each tanker can complete, so more ships are needed to move the same volume.

Analysis — Who Pays for the Freight Squeeze

The second-order effect runs through the crack spread. When freight sets the marginal price, the gap between benchmark futures and what refiners pay at the gate can widen. Refiners with access to cheaper logistics, or with the ability to source from nearby Atlantic Basin grades on smaller ships, are relatively better placed than those dependent on long-haul VLCC economics.

Atlantic Basin grades moved on smaller ships carry higher per-barrel freight. That is a possible headwind for their competitiveness in distant markets, even as it pulls Aframax and Suezmax tonnage into service. Shipowners with exposure to those classes see the tightness first; the crude futures curve sees it later, if at all.

The counter-argument sits in demand. Negative European refining margins raise the risk of run cuts, which would trim crude demand. If runs fall, benchmark prices could soften even as delivered costs stay high, because the two are being set by different constraints. That is the mechanism that could make this second April shorter than the first.

Positioning follows the same logic. Freight exposure is rewarded more directly than outright crude in this configuration, which is the note's central implication. The flow is toward the vessels and the delivered price, not the benchmark.

Outlook — What to Watch Next

Three things decide whether this lasts. First, the pace of Hormuz flows: September's roughly 12 million barrels per day was well above the July-August run rate of about 7.5 million, and a sustained step-up would keep pulling fleet capacity into the region. Second, rates for smaller tanker classes, which signal how far the VLCC shortage has spread into Suezmax and Aframax markets.

Third, any shift in US pressure on Iranian shipping. Around 125 Iranian VLCCs are currently shut out of the mainstream market; a change in enforcement would alter the effective fleet size in either direction. JPMorgan does not forecast which way that breaks.

Watch VLCC utilisation as the headline gauge. Above four in five vessels in active service, the buffer is thin, and voyage-length shocks pass straight into delivered costs. Below that, the squeeze has room to ease.

Frequently Asked Questions

What does the tanker crunch mean for retail investors?

It means freight, not crude, is the binding constraint. For investors, the read-through is that tanker operators and freight-linked exposure capture the move more directly than outright crude futures. JPMorgan's note frames delivered crude prices as the signal to watch, since that is where the marginal cost is being set. Retail investors holding broad energy exposure see it indirectly, through refining margins and crack spreads rather than headline crude.

Why did European refining margins turn negative again?

The report links it to the same shipping strain. Delivered crude costs have climbed back to spring highs, which raises the input cost for refiners while product prices have not kept pace. Negative margins raise the risk of run cuts. JPMorgan does not specify the exact margin level, only that European refining margins have slipped below zero again, matching the pattern seen in April.

How many tankers are tied up by US measures on Iran?

Around 125 Iranian VLCCs, roughly 13% of the global fleet, are effectively unavailable to the mainstream market under US measures. Many are anchored or drifting in the Gulf or off Sri Lanka and Malaysia. JPMorgan treats these vessels as removed from commercial service. Their absence tightens the pool available for non-Iranian Middle East crude, which the bank estimates now needs 35 extra VLCCs.

Bottom Line

The marginal barrel is now priced by the ship that carries it, not the crude itself.
