NYMEX WTI Crude Retreats From $104 as U.S. Diesel Breaks $6 for the First Time

NYMEX WTI Crude Retreats From $104 as U.S. Diesel Breaks $6 for the First Time After a four-standard-deviation spike above $104, NYMEX WTI crude front-month pulled back toward $100; retail diesel crossed $6 a gallon nationwide, a U.S. record. Diesel broke $6 a gallon nationwide in the United States for the first time on record, and crude was close behind it. NYMEX WTI crude front-month topped $104 a barrel before retreating, a spike Bloomberg Surveillance described as a four-standard-deviation event. With markets closed for the weekend, the contract was at $99.99 on September 12 (2026-09-12), while ICE Brent crude front-month stood at $104.32, more than four dollars above NYMEX WTI.^6,7 Jeff Currie, founder and CEO of Real Macro and formerly head of Goldman Sachs' commodities research desk, told Bloomberg Television on Friday (2026-09-11) that $5 gasoline is likely before the midterm elections. Diesel's record reflects a supply shock that crude benchmarks have been slower to capture. CNBC reported that gasoline prices were running about 30% above year-ago levels and diesel up 46% as of mid-August (2026-08-18), figures pointing to tighter refined product markets beyond what the crude strip suggested.^6,2 Currie had made this point publicly before. With ICE Brent crude front-month near $90.94 as of mid-August (2026-08-18), he argued that fuel prices were already registering a more severe supply shock than the crude benchmark acknowledged.² The pressure originates in the Strait of Hormuz. Escalating confrontations between the United States and Iran have progressively restricted oil transit since late August. ICE Brent crude front-month topped $101 for the first time since July on Wednesday (2026-09-09), settling more than 3% higher that session, while NYMEX WTI crude front-month traded near $96. Rigzone reported the global crude benchmark was up around 65% on the year.⁵ Vessel traffic through the strait collapsed to just four ships during the week of August 31 (2026-08-31), Blockonomi data showed, as military confrontations spread to Kuwait, Bahrain, and Jordan. NYMEX WTI crude front-month was poised for a 10% weekly surge in that period, with ICE Brent crude front-month approaching 7% gains and reaching six-week highs.³ Roughly 100 million to 120 million barrels of crude sat trapped inside the strait following a supply surge in late June and early July, Oilprice.com reported. That volume has buffered global inventories for now. But if transits stay this thin, those barrels convert from a potential release valve into an unreachable stockpile.² The pace of the move is clear from the settlement record. ICE Brent October 2026 settled at $89.57 on August 27 (2026-08-27), while NYMEX WTI October 2026 closed at $83.53 the same day. By September 4 (2026-09-04), ICE Brent had surged more than 7% to above $95.52 and NYMEX WTI had risen more than 10% to near $92, its strongest seven-day run since mid-July.⁴ Trend-following commodity trading advisers were sitting at 91% long in Brent and NYMEX WTI crude front-month as of Wednesday (2026-09-09), up from 45% and 36% respectively in late August, Rigzone reported. A clean de-escalation in the Strait, whether through Iran-Oman diplomacy or a ceasefire, could trigger a significant unwind in a crowded book.⁵ In the products market, companies appear to be drawing inventories toward minimum operating levels rather than restocking at current prices, according to Macro Voices analysis. That leaves little cushion if a further supply disruption follows.¹ Currie's $5 gasoline call requires crude to hold its recent range. NYMEX WTI crude front-month retreated roughly four dollars from its peak to end the September 12 (2026-09-12) session below $100. The next concrete signal is vessel traffic data from the strait — with transits near zero, even a modest re-opening shifts the calculus for a speculative book that has gone from one-third long to nearly fully long in two weeks.^6,7,3,5
