Asia refuses to lock in 2027 oil, pushing supply security into spot

Noise in the price, signal in the contract

On 20 October the market was talking about diplomacy. CNBC reports that December Brent touched $111.99 intraday before closing 0.7% lower at $108.79. The trigger was the arrival in Tehran that evening of Pakistan's army chief, Asim Munir, on his fifth visit. Yet according to a Reuters report carried by The National, Iranian officials say they are deliberately dragging out talks until the 3 November midterms and expect no breakthrough before the vote. The previous four mediation visits also knocked the price down without producing progress, which is why the day's headline is noise.

The signal arrived quietly on the same day. OilPrice.com, citing Bloomberg sources on 20 October, reported that Asian refiners and Saudi Arabia cannot agree on 2027 term crude contracts. A term contract commits a buyer to lift a set volume at a formula price over 12 months, and in Asia such deals are usually settled at the end of October. Our thesis is that the constraint on Gulf supply is migrating from the strait to the contract as it rolls into 2027. When the buyer will not commit 2027 volumes, the producer must sell its barrels on the spot market month by month and absorb the freight itself.

1 · The logistical constraint and its threshold

As of 21 October the physical constraint still sits in the strait. IMF PortWatch data relayed by Straits.live show only 4 ships transited Hormuz on 18 October, against a pre-crisis average of 85 a day. Vitol's head of Asia told Reuters that roughly 80 VLCCs are now tied to shuttle runs through the strait and ship-to-ship transfers in the Gulf of Oman. According to Cyprus Shipping News, the Gulf–China VLCC route earned 1,356,523 dollars a day on 15 October; the US Gulf–China route rose 108.2% in a month to 603,486 dollars.

The threshold shows up in hull numbers, and the 80 tied-up VLCCs define it. A VLCC carries 2 million barrels and an Aframax about 600,000; Taiwan's CPC last week took 6 Aframax cargoes instead of its usual 2–3 VLCCs a month. As 80 ships from the supertanker pool stay locked into the strait, the cost of moving crude from the Atlantic to Asia has risen to 40 dollars a barrel and the arbitrage has effectively shut. Asia is left with 2 options: pay more to ship on smaller vessels, or buy delivered cargoes from Gulf producers. The second option moves risk out of the 12-month term contract and onto the producer's monthly spot sales.

2 · Supply security and critical thresholds

Gulf supply tightened again in the first 15 days of October. Kpler data cited by the Saudi Gazette put Saudi exports at 5.55 million barrels a day on 1–15 October, down from 7.16 million in September. The loss comes from the Gulf coast: Ras Tanura fell from 4.16 million to 2.98 million barrels a day, while Yanbu held at 2.34 million. The threshold to watch for supply security is an October average below 6 million barrels a day. A close below that line would show September's recovery as temporary and vindicate Asian buyers' caution over 2027 volumes.

The other buffers have also thinned this autumn. OilPrice.com reports that Russia's seaborne crude exports fell to 3.13 million barrels a day in the week to 18 October, the lowest since March; Primorsk did not load for about 3 days. OPEC estimates put Russian output at 8.64 million barrels a day in September, the tenth consecutive monthly decline. On the gas side, Reuters reports that Norway's September output of 298.4 million cubic metres a day was 6.7% below forecast. The Ormen Lange outage will cut deliveries by 7.9 million cubic metres a day until 1 February 2027.

3 · Second-round effects

With 2027 contracts unsigned, the cost first shows up in price differentials. Reuters reports that the Dated Brent premium hit a record above 20 dollars last week, while some West African grades fell to minus 20 dollars. The same source says ADNOC sold delivered cargoes to Asia for the next 2 months, and Aramco for November, with the producers bearing the freight. With the Gulf–China VLCC rate at 1.36 million dollars a day, freight is eating into the producer's net revenue per barrel. Formosa Petrochemical says net refining margins on Middle East crude stayed above 10 dollars after freight and insurance; the buyer can pay, but will not lock in volume.

Türkiye's link in the chain runs through the Mediterranean this winter. OilPrice.com reports that European refiners are turning to nearby crude because of high freight, and North Sea Johan Sverdrup traded at a 24-dollar premium to Brent. As competition for cargoes arriving in the Mediterranean intensifies, Turkish refiners' crude costs will be set not by the futures price but by these record premiums of 20–24 dollars. This is an inference; Turkish refiners' October purchase costs were not given in the sources as of 21 October and could not be verified.

4 · What would refute this reading

The thesis rests on two conditions: Asian buyers declining to commit 2027 volumes, and 80 VLCCs remaining locked into the strait. If Aramco announces a compromise by the end of October that counts 2026 spot purchases towards term volumes, and Asian buyers keep their 2027 volumes, the constraint unwinds at the contract level. If daily Hormuz transits on IMF PortWatch rise above 20, the VLCC pool is freed and the arbitrage reopens. If either development appears by 15 November, we will abandon this reading. Our calibrated probabilities: a spot-heavy year continues 55%, a term-contract compromise 30%, the strait reopens 15%.
