Middle East Supply Disruptions Drive Heating Oil Futures to Multi-Year Highs

Heating oil futures on NYMEX (HO) have advanced 51.3% in the past three months, reflecting the sharpest rally in refined products since the 2022 market shock. The move is primarily driven by sustained supply disruptions in the Middle East following the closure of the Strait of Hormuz, compounded by widespread refinery outages, depleted inventories, and record-high refining margins across key global markets.

Historic Supply Shock and Refinery Outages

The immediate catalyst for the rally in heating oil has been the closure of the Strait of Hormuz in late February 2026, following US-Israeli military action and Iranian retaliation. As the world’s most important energy chokepoint, the blockage removed around 20% of global oil supply from the market and sharply reduced both crude and refined product flows. The disruption was quickly compounded by drone and missile attacks on Saudi and Russian refineries, which together pushed global refinery outages to 7.8 million barrels per day in September, with projections as high as 8.5 million barrels per day for October.

This supply shock hit distillates hardest, as Russian and Middle Eastern outages curtailed exports of diesel and heating oil to Europe and the US. Russia, previously a major supplier, halted all diesel exports, exacerbating shortages in the Atlantic Basin. Simultaneously, China reduced its product exports and global maintenance and unplanned shutdowns further strained supply chains.

Inventories and Margins Signal Market Tightness

Heating oil futures’ gain is also underpinned by historically low inventories and record refining margins. US distillate inventories fell below 100 million barrels in September—13% below the five-year average—and are expected to remain at multi-year lows through 2027. OECD and European product buffers have also been drawn down rapidly, with Europe’s jet and distillate reserves slipping under the IEA’s comfort threshold.

These shortages have been reflected in crack spreads, which reached $87.02 per barrel for diesel and over $62 per barrel for heating oil, well above historical norms. US refineries have operated at 97–98% utilization through the period, near physical limits, but have not been able to offset the loss of imported barrels. The combination of high utilization, low stocks, and robust export demand for US distillates has kept domestic supply tight and sustained the rally in heating oil futures.

Broader Market Positioning and Structural Factors

The market’s response has been amplified by the absence of new refining capacity and the structural limits on product supply. No new US refinery has been built since 1976, and several facilities are scheduled for closure or conversion, particularly in California. As a result, the sector’s ability to respond to price signals is limited, and crack spreads have behaved as if crude oil were priced well above actual benchmarks. The product market has shifted from being set by marginal refinery costs to being determined by inventory drawdowns and demand destruction.

At the same time, government releases from the US Strategic Petroleum Reserve (SPR) and international emergency stocks have mitigated crude price escalation but provided only partial relief for distillate markets. The US SPR has fallen to 243 million barrels, its lowest since 1983, reducing the government’s flexibility to respond to further supply shocks. High US exports—averaging 1.2 million barrels per day for distillates in the first half—have supported European supply but contributed to tightness at home.

Risks and Catalysts for the Forward Outlook

The outlook for heating oil remains highly sensitive to geopolitical developments, refinery outage resolution, and inventory trends. A normalization of flows through the Strait of Hormuz, recovery in Middle Eastern and Russian refining capacity, or a mild winter could alleviate some pressure and prompt a correction in futures. Conversely, renewed supply disruptions, unexpected refinery outages, or a cold snap in the US Northeast could sustain or accelerate the rally, especially given low inventories and limited policy headroom. The next scheduled inventory reports, OPEC+ supply decisions, and progress toward reopening critical shipping lanes will be closely watched by market participants.

For now, the market continues to price in ongoing tightness in distillate supply, with risk premia elevated and volatility likely to remain high until physical flows normalize and inventory buffers are rebuilt.
