Hormuz Scenario Revision and Long Nuclear Timelines Keep ULSD Bids Firm
Rystad's upgraded Iran risk framework and the decade-long wait for U.S. small modular reactors both support near-term distillate demand.
Rystad Energy flagged "renewed deterioration in security conditions around the Strait of Hormuz" in a market update sent late Thursday (2026-07-16), revising its four-scenario U.S.-Iran framework and broadening the range of geopolitical risk premiums it considers plausible in oil prices. NYMEX ULSD heating oil front-month was holding at $4.17 per gallon as of early Monday (2026-07-20), with ICE Brent crude front-month at $90.21 per barrel, down a fraction on the session.4
The revision carries direct implications for distillate markets. ULSD prices track crude with a lag, and any escalation at the strait would disrupt not just Persian Gulf crude flows but the middle-distillate cargo routes that supply Asian and European refiners in the fourth quarter. Rystad assigned just a five percent probability to a full resolution, which it said would "largely eliminate" the geopolitical risk premium embedded in oil. Everything else — the remaining 95% of its probability mass — involves some degree of maritime disruption.4
Rystad's base case remains a narrow deal and a "managed strait," described as the most politically workable outcome for both sides. Under that scenario, the consultancy projected strait traffic recovering to roughly 10 million barrels per day by mid-August and approximately 14 million barrels per day by October. That gap, stretching across summer into early autumn, is where heating oil traders face the sharpest uncertainty heading into the demand season.4
The four scenarios imply, in Rystad's own framing, "a wide range of geopolitical risk premiums." Before any deal date, the key variables include the intensity of military and maritime attacks, the degree of U.S. blockade enforcement, Iranian export volumes, and the pace of initial crude recovery — none of which are stable. The VIX climbed 12.33% to 18.77 as of early Monday (2026-07-20), a sign that broader markets are pricing more tail risk than a week ago.4
The nuclear policy angle supplies a slower-moving but complementary argument. New Jersey moved last week (week of 2026-07-17) to commit to small modular reactors as a route to its 2050 capacity targets, drawing immediate pushback from a Wall Street Journal op-ed arguing the administration was "chasing unproven technology" when large-scale conventional reactors remained the available alternative. Whether SMRs or conventional plants win that debate is secondary to the timeline: neither arrives this decade in material volume.6
The IEA projects more than 70 gigawatts of new nuclear capacity online by the mid-2030s, one of the strongest pipelines in 30 years. BNEF puts global nuclear capacity at 535 gigawatts by 2036, a 44% increase from 2025's 372 gigawatts installed. But those figures are aggregated across China, where 60 already-operating reactors carry 125 million kilowatts of installed capacity, and Japan, where rebuilding 14 reactors by 2050 would add 16 gigawatts to a grid that still draws 60% to 70% of its electricity from imported hydrocarbons.5,2,1
New Jersey's bet, in other words, describes a structural ambition that leaves oil-fired peaking and distillate heating demand largely intact through the current decade. The World Nuclear Association projects uranium demand climbing 28% by 2030 to nearly 87,000 tonnes annually, which confirms real momentum — but momentum measured in years, not quarters.3
The U.S. data-center power demand case reinforces the same point. IEA projections show U.S. data-center electricity consumption more than tripling over the next decade, from 34.7 gigawatts in 2024 to 106 gigawatts by 2035. That load cannot be served by reactors that have not yet received permits. Oil and gas fill the gap in the interim.1
The two stories land on the same distillate read from opposite directions. Hormuz disruption risk pulls ULSD higher through the crude channel — tighter Iran sanctions lift the Brent risk premium, and ULSD follows. The nuclear policy push, paradoxically, reinforces that same bid by confirming how distant the structural demand replacement actually is. The European Commission's March 2026 pledge of €200 million for next-generation SMRs sits in the same category.1,6
The number to watch before autumn is Rystad's managed-strait traffic estimate for October: 14 million barrels per day. At that level, crude flows normalize and the risk premium compresses. Short of it, the Hormuz premium holds, and ULSD carries its bid into the heating season with nuclear timelines too long to argue otherwise.4
