One-Third of the Heating-Oil Reserve Is on Loan: Refiners Now Own the $106 Distillate Crack, and December's Hike Is Priced In

On October 21, 2026, the Department of Energy offered to loan up to 315,000 barrels of heating oil out of the Northeast Home Heating Oil Reserve, the federal store of ultra-low-sulfur diesel that sits in South Portland, Maine, Boston, Groton and New Haven, Connecticut, and New York Harbor. Deliveries have to be finished by November 13, and the oil goes to fuel retailers and terminal operators through the agency's email-auction process so it can be pulled into the tightest corners of the Northeast. Energy Secretary Chris Wright called it a commitment to doing everything in the power of the government to lower energy costs. Diesel is cut from the same refining stream as heating oil, which is why record pump prices above $6.50 a gallon got Washington's attention in the first place.

Washington's stock of barrels has always been crude, and that is now the problem. The Strategic Petroleum Reserve has been leased out in successive tranches through 2026 — 53.3 million barrels in May, a request for proposals covering up to 92.5 million barrels, and 40 million more in late September — but none of that adds a gallon of diesel. A barrel of SPR crude still has to be distilled, and the refineries that feed the East Coast are already running at the ceiling: US utilisation averaged 95% in the third quarter of 2026, the highest for a third quarter since 2019, and stood at 93.5% in the week ending October 9. The reserve is also emptying. The one product reserve the government owns is the one it just spent a third of, in the middle of a heating season.

The crack spread is what a refinery earns converting a barrel of crude into a barrel of product, and the distillate crack is the price of the middle of the barrel: diesel, jet fuel and heating oil. The New York Harbor ultra-low-sulfur diesel crack averaged $106.51 a barrel in the week to October 2, 2026, after $114.54 the week before and $115.83 the week to September 18. It was $102.19 in early September and $48.66 before the year turned. Brent settled at $109.49 on the same day the heating-oil loan was announced, so the refining margin on a barrel of diesel is now worth as much as the crude in it.

The scale of the transfer is visible in the filings. In the same quarter a year earlier, Valero Energy earned $2.28 a share and Phillips 66 earned $2.15; eighteen months earlier Valero lost $1.90. Marathon Petroleum, Phillips 66 and Valero Energy together booked $12.6 billion of profit in the second quarter, the most since Russia invaded Ukraine, against $2.9 billion a year earlier. The ownership of the bottleneck has moved to the firms that own distillation capacity, and the profit is landing in their income statements before it reaches anybody's gas tank.

The upstream looks comparatively small. EOG Resources earned $6.9 billion of net income and $12.92 a share in the trailing twelve months to June 2026 on $26.7 billion of revenue, against a Brent that has averaged above $109 this month. The barrel pays less than the crack does: the same window delivered $24.12 a share at Valero and $29.05 at Marathon Petroleum, and the difference is a spread, not a commodity.

A windfall only matters once it is converted. Over the twelve months to June 30, 2026, the three biggest US refiners generated $37.0 billion of operating cash flow and spent $15.5 billion of it on buybacks and dividends — about $10.9 billion of stock and $4.6 billion of cash. Valero Energy alone repurchased $4.8 billion of stock in that window, roughly 3.9% of the $124.8 billion it is worth today, and still ended the period holding $8.1 billion of cash. Capital intensity is the reason the crack is so convertible: refining spent $788 million over the same window.

Jet fuel is distilled alongside diesel and priced off the same market, and the crack spread is therefore an airline cost. Delta Air Lines set out the arithmetic in its third-quarter filing: aircraft fuel and related taxes rose to $4,351 million from $2,570 million a year earlier, on fuel consumption that was essentially flat at 1,146 million gallons against 1,138 million. The average price per gallon rose 68% to $3.80, a hedging programme built for a quieter market produced $416 million of losses against $21 million a year earlier, and the operating margin fell to 7.2% from 10.1%.

The Northeast shortage is the local end of three foreign supply shocks, and each one drained the same global pool. Strikes on Russian refineries took out diesel-heavy capacity and Russia banned diesel exports in July 2026, tightening the market for buyers from the US to Europe. China halted gasoline, diesel and jet fuel exports in early October. Disrupted Middle Eastern refining closed off another tranche of supply at the same time. What is left is a market where the marginal barrel of middle distillate is set by whoever has a refinery still running, and the US East Coast, with no refinery of its own to call, is the buyer at the end of the queue.

The Federal Reserve raised its target range to 3.75%–4.00% on September 16, 2026, in a unanimous 12-0 vote, and the next move is already being priced. Interest-rate futures put a 27% chance on an increase at the October 27–28 meeting and an 89.5% probability on a move in December. Twelve of the thirteen major houses Reuters canvassed expect 25 basis points in December to 4.00%–4.25%, with BofA alone expecting two hikes this year to 4.25%–4.50%. The argument is no longer about whether the Fed tightens; it is about how the energy print lands in the inflation data the committee will read in November.

That forward curve is the December base case in one line. A crack of $106.03 in October falling to $97.43 by December and $95.21 by January is precisely the profile a hiking committee needs: the level stays high enough to keep headline inflation uncomfortably positive, but the month-on-month impulse fades before the vote. The EIA's own October outlook is more bearish still, with Brent averaging $105 in the fourth quarter, $84 in 2027 as flows recover and inventories rebuild, and retail diesel averaging about $4.50 a gallon next year. The reserve loan does not change any of that. It is a note from a government that has run out of barrels, written in the same week the market decided the crack would ease on its own.
