Will Diesel Price on October 31, 2026 be above $6.30?

- [2026-09-29] EIA's official weekly Gasoline and Diesel Fuel Update reported the U.S. average on-highway diesel price was $6.382 per gallon, down $0.147 week-over-week, for the week ending September 28, 2026. Next EIA release scheduled October 6, 2026. (https://www.indexbox.io/blog/eia-weekly-fuel-update-national-gasoline-slips-to-4465-as-diesel-falls-to-6382/) - [2026-09-28] A data aggregator tracking the same EIA series confirmed US on-highway diesel averaged $6.382/gal in EIA's latest Monday release, moving -14.7 cents on the week (down) , and noted it is 70% above its 5-yr median for the week . (https://mondaydiesel.com/stats) - [2026-09-07] EIA's weekly survey had shown diesel at a then-record weekly record at $5.967 per gallon , which subsequently rose further before the late-September pullback. (https://shalemag.com/us-diesel-prices-2026-record/) - [2026-09-04] Kalshi itself publicly flagged that US diesel prices just hit an all-time high of $5.82 per gallon in early September, underscoring the sharp run-up through the month. (https://x.com/Kalshi/status/2095788958475309114) - [2026-10-06] CNBC reported that the U.S. national average price of diesel topped $6 a gallon in September for the first time ever , attributing the spike to tight global supply. (https://www.cnbc.com/2026/10/06/us-diesel-fuel-prices-iran-ukraine-energy-crisis-.html) - [2026-10-06] Crypto Briefing, citing AAA, said US retail on-highway diesel peaked at approximately $6.53 per gallon that month, after pushing past the $6.50 mark in September. (https://cryptobriefing.com/kalshi-traders-us-diesel-prices-620/) - [2026-10-05] President Trump signed an executive order that directs the Secretary of the Treasury... to defer payment of the Federal excise tax imposed for on-road use of dyed diesel fuel for the remainder of the year without interest or penalties, and to explore pathways to eliminate the obligation to pay the deferred taxes . (https://www.whitehouse.gov/fact-sheets/2026/10/fact-sheet-president-donald-j-trump-promotes-diesel-affordability/) - [2026-10-06] Reporting on the order noted the policy context: diesel averaged $6.32 a gallon nationwide at time of signing, and that a trucker filling an 18-wheeler could save roughly $150 using untaxed dyed diesel instead. (https://time.com/article/2026/10/06/us-dyed-diesel-federal-highway-tax-fuel-costs-trump-farmers/, https://edition.cnn.com/2026/10/05/business/trump-diesel-prices-executive-order) - [2026-10-06] Euronews cautioned the order is narrower than advertised: it does not abolish the levy but postpones payment on dyed diesel used on roads between 5 October and 31 December, free of interest and penalties , meaning retail pump prices for ordinary (clear) taxed diesel are not directly cut by federal fiat — only substitution toward dyed diesel by those willing to use it could lower observed averages. (https://www.euronews.com/2026/10/06/trump-defers-diesel-tax-for-truckers-as-fuel-costs-bite-weeks-before-us-midterms) - [2026-10-05] CNN quoted an analyst skeptical of fast effects: "Washington is great at making something sound easy that is not. Just because you're allowing something to happen, doesn't mean it will," De Haan said. "This won't fix the problem overnight, but it can allow politicians to take a bit of a victory lap." (https://edition.cnn.com/2026/10/05/business/trump-diesel-prices-executive-order) - [2026-09-03] EIA's September Short-Term Energy Outlook forecast diesel to stay elevated, noting U.S. distillate fuel oil inventories will drop below 100 million barrels in September and will remain below the five-year low through much of 2027, as tightness in the global distillate market has raised domestic prices, with global distillate production expected to remain below last year's levels, contributing to low U.S. diesel inventories and high diesel prices ; the STEO's monthly retail diesel forecast for 2026 was raised to $5.07/gal (annual average), up from $4.85 previously. (https://www.eia.gov/outlooks/steo/) - [2026-10-06] State-level action preceding the federal order: between September 23 and October 2, ten states — including Texas, Oklahoma and Alabama — took steps to boost access to dyed diesel for use in highway vehicles, states that make up about a third of diesel sales , suggesting some regional downward pressure may already be underway before the EIA's October 6 reading. BOTTOM LINE: The most recent official EIA reading (week of Sept. 28, 2026) put national on-highway diesel at $6.382/gal, already down 14.7¢ from its late-September peak above $6.50-6.53 (AAA); a new Trump executive order deferring (not eliminating) the federal 24.4¢ excise tax on dyed diesel for highway use, signed Oct. 5, 2026, could exert further modest downward pressure on measured pump prices by late October, but experts caution the effect may be gradual and incomplete, leaving the $6.30 threshold a close call heading into the Oct. 31 close. NOT FOUND: The EIA's October 6, 2026 weekly release (due same day as this report) was not yet captured in search results, nor was any diesel reading for the week of October 5 or later; no official confirmation yet of how much the dyed-diesel order has moved EIA's measured retail average.

- [2026-10-05] AAA's national average retail diesel price stood at $6.32–$6.34/gal, down slightly from a week earlier, continuing a pullback from the recent peak. US - AAA Daily National Average Gasoline Prices Diesel 2026-10-05 6.32 https://en.macromicro.me/series/23010/aaa-daily-national-average-gasoline-prices-diesel - [2026-09-28] EIA's official weekly on-highway diesel survey (the standard reference series) showed the U.S. average at $6.382/gal, down 14.7 cents from the prior week's $6.529, after a week-over-week run of 6.285 → 6.529 → 6.382. https://www.eia.gov/petroleum/gasdiesel/ - [2026-09-07] Diesel hit a nominal weekly record of $5.967/gal, surpassing the prior all-time weekly high of $5.810 set in June 2022, before continuing to climb into the $6.3–6.5 range by late September. U.S. diesel prices hit a weekly record at $5.967 per gallon. Robert Rapier examines whether 2026 could set a new annual average. https://shalemag.com/us-diesel-prices-2026-record/ - [2026-09-10] Historical base rate: diesel's nominal annual-average record was set in 2022 at $4.989/gal, and the author's extrapolation showed diesel would need to average about $5.20/gal in the remaining weeks of 2026 to beat that record — a bar 2026 prices are now running well above. Using EIA's 36 weekly price observations through September 7, I calculate a 2026 year-to-date average of about $4.895 per gallon for diesel and $3.772 for regular gasoline. That leaves 16 weekly observations for the rest of the year. https://shalemag.com/us-diesel-prices-2026-record/ - [2026-09-09] EIA's Short-Term Energy Outlook (STEO), the most authoritative institutional forecast, raised its 2026 annual diesel price forecast sharply to $5.07/gal (from $4.85 previously), reflecting persistently tight distillate markets. Release Date: September 9, 2026 Forecast Completed: September 3, 2026... Retail diesel price (dollars per gallon) | $5.07 | $4.40 | Previous forecast | $4.85 | $4.07 https://www.eia.gov/outlooks/steo/ - [2026-09-09] EIA's STEO framed the drivers as structural/geopolitical rather than transient: We forecast U.S. distillate fuel oil inventories will drop below 100 million barrels in September and will remain below the five-year (2021–2025) low through much of 2027. Tightness in the global distillate market has raised domestic prices and incentivized U.S. exporters to increase distillate exports. We assume global production of distillate fuel will remain below last year's levels in the coming months, contributing to low U.S. diesel inventories and high diesel prices. https://www.eia.gov/outlooks/steo/ - [2026-09-10] Comparable historical episode: the 2022 diesel price spike (Russia's invasion of Ukraine, tight refining capacity, low inventories) drove diesel to roughly $5.80–5.97/gal at peak and ~$4.99/gal annual average; that spike eventually subsided over many months, illustrating that diesel shocks of this magnitude have historically persisted for multiple quarters rather than reversing within weeks. https://shalemag.com/us-diesel-prices-2026-record/ - [2026-10-04] Independent daily tracking (AAA via MacroMicro) confirms diesel near $6.34–$6.36/gal in early October, i.e. still roughly $1.30–1.40 above EIA's own full-year 2026 average forecast, underscoring how far above "normal" base-rate levels current prices are. Diesel 2026-10-04 6.34 USD/Gallon 6.36 USD/Gallon https://en.macromicro.me/collections/27425/oil-spread/80621/aaa-daily-national-average-gasoline-prices - [2026-10-05] AAA/Gasolytics state-level tracker shows the week-over-week trend is modestly downward (national average down $0.13 week-over-week as of 10/5), consistent with diesel having peaked in late September. Today's average diesel price for all 50 states and DC, updated 10/5/26 from AAA — the national average is $6.32/gal... National diesel average$6.32▼ −$0.13 wk https://www.gasolytics.com/diesel-prices-by-state - [2026-09-10] Seasonal base rate favors diesel staying elevated into October/November: EIA has found that U.S. distillate consumption increased by an average of about 4% from September to October over the five years from 2019 through 2023 (per the article's citation of EIA data on harvest/heating-season demand), reinforcing that diesel typically firms, not weakens, in this period. https://shalemag.com/us-diesel-prices-2026-record/ BOTTOM LINE: There is no established historical precedent for diesel trading this high before 2026 (prior record ~$5.81–5.97/gal in 2022 vs. current ~$6.3–6.4/gal), so there's no long "base rate" track record for prices sustaining above $6.30 — but the current level is already above the $6.30 threshold and recent weekly readings (EIA $6.382 on 9/28, AAA ~$6.32-6.36 through 10/5) sit right around or above that line with only a modest recent pullback from a higher peak (~$6.53 the prior week), while the fall/winter seasonal pattern and EIA's own upgraded STEO forecast both point toward continued elevated (not sharply falling) diesel prices through late October. NOT FOUND: No historical Kalshi/prediction-market track record for diesel-price contracts could be found (this appears to be a relatively new contract type with no visible prior resolution history); no explicit day-by-day EIA/AAA diesel price data for the period October 6–31, 2026 (future dates) was available, since those readings have not yet occurred.

YES means: the national (EIA on-highway) diesel price reading for/around October 31, 2026 comes in above $6.30 per gallon. - [2026-10-04] Independent daily tracking shows diesel still above the threshold even after the recent pullback: AAA's national average stood at AAA's national diesel average set a record of $6.5276 a gallon on 22 September and had eased to $6.343 on 4 October after the G7 release , i.e. 1.3¢ above $6.30 even after a coordinated strategic-reserve release. - [2026-10-06] The underlying supply shock has not resolved: a tracker citing Windward/UKMTO data reports On Day 219 the strait remains CRITICAL: President Trump rejected Iran's seven-day reopening plan on 26 September and a renewed proposal around 1 October, at least four tankers were struck there between 1 and 4 October, and Windward counted 119 transits in the week of 23–30 September against about 130 a day before the war. - [2026-10-04] Even the G7's emergency action was product-specific and only partially effective: the week saw the G7 agreed to release 100 million barrels of diesel and crude from strategic reserves , yet diesel barely dipped below its record and remains above $6.30 nationally. - [2026-10-04] Fundamental mechanism favoring persistence: US commercial crude stocks built 0.9 million barrels to 427.3 million in the week to 25 September, about 2% above the five-year average, while distillate drew again to 105.2 million, about 13% below it (EIA). Crude can be rerouted around a closed strait; refinery yield and distillate inventory cannot. - [2026-09-21] Expert commentary from the week diesel first broke records projected further gains, not a reversal: U.S. diesel fuel has reached a record national average of $6.29 per gallon... Muenster expects prices to continue rising through at least mid-November. - [2026-09-21] The most bullish professional voice, Tom Kloza of Gulf Oil (as carried in Overdrive), argued the market was "untethered" and that the U.S., Europe and Asia "could see diesel prices of $8-$10/gallon before this is all over." - [2026-09] Analysts at Barclays framed the U.S. as now the marginal global diesel supplier amid lost Gulf/Russian refining capacity, reinforcing structural (not transient) tightness: "Global diesel markets are under immense pressure. The Iran and the Ukraine wars have resulted in cutting the supply from refineries in the Gulf and Russia, making the US the crucial supplier of distilled petroleum products," analysts at UK bank Barclays said. - [2026-09] EIA's own institutional modeling embeds a seasonal upside case through exactly the contract window: crack spreads were modeled to stay above $2 per gallon through November 2026, then decline steadily into mid-2027. The key assumption is a return of more normal tanker traffic through the Strait of Hormuz — an assumption the Oct 1–4 Hormuz strikes and Iran's rejected reopening proposals directly undercut. - [2026-09] Global demand for U.S. barrels remains elevated, crowding out domestic supply: October bookings for leasable diesel storage across North America and the Caribbean Islands reached 13 million barrels — a four-year peak — compared with just 11 million barrels available back in June... leases are going unsigned because there is little diesel available to store . - [2026-09] A global supply-and-demand outlook from Reuters-sourced reporting sees no near-term resolution: a worldwide shortage fueled by conflicts in Iran and Ukraine shows little sign of easing before next year , and the same piece notes a flare-up risk could still send prices "sharply higher" before October 31. - [2026-09-21] Seasonal demand is set to reinforce prices into the contract's late-October window, as fall/winter brings both harvest and early heating-oil draws on the same distillate pool while refinery maintenance reduces output (EIA STEO), a dynamic already cited by colleagues but whose timing lines up precisely with the Oct 31 close. - [2026-10-05] Politically, the only countermeasure so far (Trump's dyed-diesel tax deferral) is narrow, voluntary, and was itself signed when the national average was still measured at $6.32 — i.e., already above the $6.30 strike at signing — undercutting the case that policy alone pushes the reading below threshold by month's end. BOTTOM LINE: Every independent, more-recent-than-Sept.-28 data point (AAA daily series through Oct 4-5, the Oct 5 executive-order coverage, and the Oct 4 global tracker) still shows the U.S. diesel average sitting at $6.32–$6.38, only a few cents above the $6.30 strike, while the structural drivers (Hormuz still contested, distillate stocks ~13% below five-year average, elevated crack spreads modeled through November, and seasonal fall/winter demand) all point toward prices holding near or above $6.30 rather than falling meaningfully by October 31. NOT FOUND: No EIA weekly reading for the week of October 5 or later (the Oct 6, 2026 release content itself) was retrievable in search results; no diesel-specific data yet reflecting any measurable pump-level effect of the Oct 5 dyed-diesel executive order.

YES means: the measured U.S. diesel price reference series (EIA on-highway diesel, the de facto benchmark these Kalshi diesel contracts track) printing above $6.30/gallon for October 31, 2026. - [2026-10-04] A former oil-and-gas analyst interviewed by CTV/BNN Bloomberg said flatly "it's more downside than upside," he said. "We've peaked, I think, on the diesel side." , and separately argued oil could fall "$5 minimum, maybe even $10" if Iran-U.S. tensions ease, which would pull diesel crack economics down further (https://bnnbloomberg.ca/business/economics/2026/10/04/diesel-prices-could-fall-below-2-a-litre-in-coming-months-expert). - [2026-10-02] G7 nations agreed to release 100 million barrels of diesel and crude through the IEA, starting immediately and spread over four months, with a "substantial" share of diesel in the first 20 days , directly targeting the distillate shortage that drove the spike (https://globaloilshock.com/en/diesel-shortage-winter-2026-27/). - [2026-10-02] Immediately after that G7 announcement, the European diesel future then fell 8 per cent , a sharp, same-day repricing showing the market treats the reserve release as materially bearish for distillate prices (https://globaloilshock.com/en/diesel-shortage-winter-2026-27/). - [2026-10-02] The move followed a dispute in which Trump had demanded at least 100 million barrels of diesel from Europe, and the European Commission rejected a ban on US diesel exports — i.e., the supply-release outcome was the compromise that emerged, adding a second (international) policy lever besides the Oct. 5 U.S. tax-deferral order working to cool prices into late October (https://globaloilshock.com/en/diesel-shortage-winter-2026-27/). - [2026-09-28] EIA's own weekly diesel reading has already turned down two straight prints from its $6.529 peak (week of Sept. 21) to $6.382 (week of Sept. 28), confirming the US on-highway diesel series history table 5.652→5.599→5.967→6.285→6.529→6.382 (https://www.eia.gov/dnav/pet/pet_pri_gnd_dcus_nus_w.htm). - [2026-10-05] Independent state-level tracking (AAA via Gasolytics) shows the national average already trending down week-over-week by mid-week, i.e. the decline that began in late September had not reversed as of Oct. 5 — a run of three consecutive weekly declines would put the EIA print materially under $6.30 by the Oct. 26/Nov. 2 reporting dates bracketing Oct. 31 (https://www.gasolytics.com/diesel-prices-by-state). - [2026-10-01] EIA's own crack-spread framework shows diesel's historic premium is a refining-margin phenomenon, not a crude-supply phenomenon: crack spreads, which represent the price difference between products and crude oil, can be used to determine the relative value of various petroleum products for refineries to produce... and can rise or fall depending on the time of year and on market conditions — meaning a crack-spread collapse (now underway per the G7 release and European futures drop) flows through to retail with only a short lag (https://www.eia.gov/finance/markets/products/prices.php). - [2026-10-05] South Africa's independently-calculated wholesale diesel benchmark (set from the same underlying international product prices that feed U.S. import/export parity) showed global prices pulled below $100 a barrel on Friday (2 October) as France proposed that developed nations release strategic reserves to ease surging prices at the pump , corroborating that the international price shock — the root cause of the U.S. spike — was already reversing into October (https://businesstech.co.za/news/energy/878108/south-africa-bracing-for-disaster-next-week/). - [2026-10-06] No EIA weekly release for Oct. 6, 2026 (due today) was yet indexed in search results, meaning the most recent *confirmed* official reading remains the Sept. 28 print of $6.382 — already only 8 cents above the strike and on a clear two-week downtrend, a status-quo trajectory that, if it merely continues at the same roughly 10–15¢/week pace seen the last two weeks, crosses below $6.30 within one more weekly print. BOTTOM LINE: The most recent confirmed weekly trend (two consecutive EIA declines from $6.529 to $6.382, AAA near $6.32 and still falling as of Oct. 5), combined with two converging bearish catalysts — the Oct. 5 federal dyed-diesel tax deferral and the Oct. 2 G7/IEA 100-million-barrel diesel-and-crude reserve release (which triggered an 8% one-day drop in European diesel futures) — gives the NO case a concrete, dated mechanism for diesel to drift from ~$6.38 down through $6.30 by Oct. 31, consistent with analyst commentary that diesel has already peaked. NOT FOUND: The EIA's October 6, 2026 weekly diesel print (due the same day as this report) had not yet appeared in indexed sources; no diesel reading for the week of October 5 or later was available, so the actual pace of the post-G7/post-tax-order decline through month-end cannot yet be confirmed directly.
