US Distillate Stocks Weigh on Heating Oil as Hormuz Traffic Resumes
Heating oil front-month holds near $3.53 but faces bearish inventory pressure as Middle East crude supplies resume and US product stocks begin to rebuild.
Heating oil futures were quoted at $3.53 as of Friday (2026-07-10) as traders weighed a rare build in US crude inventories against still-declining product stocks, a signal that has left distillate markets in a holding pattern even as the broader crude complex recovers from the Strait of Hormuz disruption.1
The crude build sets the tone. American Petroleum Institute data for the week ending March 22 (2026-03-22) showed crude inventories rising 1.93 million barrels, against analyst expectations of a 1.1-million-barrel draw. A week earlier, for the period ending March 15 (2026-03-15), the API had reported a 2.133-million-barrel draw that the EIA then revised to a 9.6-million-barrel drawdown. The swing reflects how abruptly the supply balance shifted once tanker traffic through Hormuz began to normalize.1
For the distillate market, the read is more complicated. Distillate inventories fell 4.278 million barrels in the March 22 (2026-03-22) reporting week, against an expected draw of only 716,000 barrels. That kind of deficit would normally support the heating oil basis. The bearish consensus on heating oil front-month, currently running at 88% across 32 tracked signals, derives instead from the supply trajectory: crude builds tend to feed product rebuilds in subsequent weeks, and the pace of Hormuz normalization has accelerated since the ceasefire that was in place by early June 2026.1
Wood Mackenzie analysts noted in late May (2026-05-20) that the reopening of Middle East shipping lanes followed President Trump's comments about "massive numbers" of empty tankers heading to load regional crude. That fleet was already carrying cargo back, Wood Mackenzie said, and the physical consequence is now working through the inventory picture. Crude is arriving again. Refineries are returning to fuller utilisation rates. How quickly that feeds into distillate stocks is the heating oil market's central calculation.2
The demand backdrop offers no offset. EIA's June Short-Term Energy Outlook (2026-06-09) projected global oil consumption to fall by more than 1 million barrels per day in 2026 relative to 2025, citing fuel disruption, elevated prices, and demand destruction triggered by the Hormuz closure. Even with a ceasefire in effect, demand had already been damaged in heavy industrial and transport segments, both large distillate consumers.4
Before the conflict, Brent implied volatility had generally run below 30% since early 2024. By March 2026 options markets were pricing it at an average of 78%, reaching 106% on March 12 (2026-03-12). That premium has since compressed sharply as lanes reopen, with ICE Brent crude front-month trading at $76.44 as of Friday (2026-07-10), well above the $67.43 handle seen in mid-May (2026-05-19) when markets were still absorbing the initial supply shock.3,1
NYMEX WTI crude front-month has recovered to $72.28, having touched $59.94 on May 19 (2026-05-19) during the peak uncertainty phase. Heating oil has not matched that recovery. The divergence reflects both the demand destruction and the distillate-specific rebuild dynamic that typically lags crude by several weeks in a reopening cycle, as crude arrives first and product output follows once refinery throughput normalises.1
EIA data showed US crude output had returned to 12.1 million barrels per day as of mid-March (2026-03-15), matching its all-time high. Combined with the tanker fleet returning to Hormuz passage, the tightness that drove outsized distillate draws in the first quarter of 2026 is fading. Across twelve reporting periods year-to-date, the net crude build totalled just 430,000 barrels on API data, showing the crisis-era drawdown has largely unwound.1
The distillate thesis turns on the next two EIA weekly releases. A second consecutive crude build feeding through to product supply would press heating oil prices lower and confirm the bearish consensus. The one risk cuts the other way: the ceasefire is fragile, and any escalation that closes Hormuz again would re-tighten distillate markets faster than any normal refinery cycle would predict. ICE Brent crude front-month is already flashing a contrarian bullish signal on supply grounds, suggesting some traders have not fully priced out that possibility.1,4
