Diesel, Not
Crude

The fuel-price bottleneck before the midterms

In September, New York Harbor diesel spot prices were up 107% from a year earlier—roughly twice the 52% rise in crude. Crude prices alone no longer tell the fuel-cost story. We examine how the measures announced before the November 3 U.S. midterm elections could work, and what the numbers mean for inflation and Korean industries.

THE BRIEF

To understand fuel costs, look beyond crude to refined products

  1. Diesel has risen far more than crudeA barrel of New York Harbor diesel cost $107.8 more than a year ago. Of that increase, $74.4—69%—came from a wider price spread over WTI (Snowshagal calculation). This is an arithmetic decomposition of two prices, not a measure of refiners' actual profits or a causal breakdown.
  2. Constraints on refined-product supply and tradeDisruptions around Hormuz and the Red Sea, strikes on Russian refineries and China's export controls have coincided. U.S. refineries entered their seasonal maintenance period, while distillate inventories were about 12% below their five-year average in the week ended September 18 (as cited by the EPA).
  3. Each policy operates through a different channelThe G7 agreed to draw on stockpiles and coordinate refinery operations; Russia partially eased its export ban, initially allowing 500,000 tonnes; and the U.S. directed relief on red-dyed diesel restrictions and a deferral of tax payments. On October 2, President Trump said the U.S. would not impose a diesel export ban. The test of these measures is actual shipments, inventories and product prices.
  4. The counterargument—and what remains unresolvedRetail diesel is 5.1% below its September 21 weekly peak, and the decline began before the policy announcements. Daishin Securities expects diesel crack spreads to narrow in the fourth quarter. But the European diesel premium widened between the October 2 and October 9 weekly closes (Snowshagal calculation), and Russian contracts and shipments remain unverified.
  5. Gasoline drives the CPI; export prices drive Korea's figuresIn July, CPI categories that include diesel carried a combined 0.22% weight (0.24% in August), far below gasoline's 3.77% (3.85% in August). September CPI rose 3.7% year on year, above the 3.6% consensus, capturing price pressure that preceded the October measures. In Korea, September petroleum-product export volumes fell 6.9% while unit prices rose 84.7%.

Why Diesel Outran Crude

Fuel prices across the U.S. have risen this year, but not at the same pace. While crude climbed by roughly half, wholesale diesel doubled. The divergence opened up in the spread between the refined product and its underlying crude benchmark.

SAME MONTHSame month, very different price gains

Using September monthly averages for both years makes the disparity clear. WTI spot crude rose 52.1% year on year; New York Harbor ultra-low-sulfur diesel (ULSD) spot prices climbed 107.4%.1, 2 At the pump, diesel rose 67.8% and regular gasoline 37.6%.3, 4 Retail prices rose less because the per-gallon total includes taxes and distribution costs that do not move proportionately with the wholesale fuel price.

The direction is consistent across sources. Eugene Investment & Securities, citing AAA, puts the year-on-year rise in U.S. diesel at 71%, compared with 56% for crude.5 Europe saw an even steeper increase: at the October 9 close, ARA diesel futures were up 117.1% from a year earlier, versus 60.6% for Brent crude.6

In September, wholesale diesel rose about twice as fast as crude

ONE BARRELBreaking down the price of a barrel of diesel

The price of diesel can be expressed as the crude benchmark plus the spread between the two. A barrel of New York Harbor diesel rose from an average of $100.4 in September 2025 to $208.2 in September 2026, a $107.8 increase. WTI accounts for $33.4 of the difference; the remaining $74.4 reflects a wider spread over WTI(Snowshagal calculation).

Of the $108 increase, $74 came from the wider spread over WTI

This is an identity: diesel price = WTI + the price spread. We can establish that the spread widened; we cannot infer that the entire widening came from refinery shortages or accrued as profit to refiners. The comparison also pairs a New York Harbor product price with WTI at Cushing, so transportation disruptions and regional supply-demand conditions matter. EIA uses crack spreads as an indicator of short-term refining profitability, but notes that they exclude other variable and fixed costs.7 Treat the figure as evidence consistent with a tighter refined-product market—potentially reflecting constraints on refining capacity, trade and logistics.

The monthly crack spread reached $110.8/bbl in September, above October 2022's $94.9 and the highest since 2021 on our EIA-based series. Daily prices, however, have reacted to policy news. The front-month NYMEX ULSD crack spread fell $6.45 intraday to $96.80 on October 9, as news of additional Russian diesel supplies emerged (S&P Global; 19:33 GMT).8 That daily futures measure is not directly comparable with the monthly spot series.

THE PUMPTwo numbers on the fuel-price sign

Gasoline is the number motorists and voters see every day. Diesel powers the trucks, farm equipment and heating systems behind the economy. EIA's weekly U.S. diesel average passed its June 2022 record of $5.810/gal in the week of September 7 ($5.967), peaked at $6.529 in the week of September 21, and eased to $6.199 by the week of October 5.3, 9 Regular gasoline averaged $4.354 that same week. The $1.845 gap is more than three times its year-earlier level of $0.587.

The gasoline–diesel gap has more than tripled in a year

Refineries and Trade Routes Under Strain

Distillation-column schematic · Crude separates by boiling point into LPG, naphtha (gasoline feedstock), kerosene/jet fuel, diesel and residue, from top to bottom · Segment heights are illustrative, not actual product yields

The widening spread suggests that refined-product supply is tighter than the underlying crude market. This year, diesel-making capacity and the routes used to move it have come under pressure at the same time. Ready-to-use diesel reserves are finite, and crude must pass through a refinery before it can become diesel.

MIDDLE DISTILLATESThe middle of the barrel

Fractional distillation yields diesel, heating oil and jet fuel/kerosene among the middle cuts—known collectively as middle distillates. That is why a diesel shortage can put pressure on jet fuel and heating oil as well. In Asian spot markets on October 9, kerosene (in the same distillate family as jet fuel) traded at $174.9/bbl, above gasoil's $162.5 (Petronet data).5

THREE ROUTESThree supply routes under pressure

MIDDLE EAST

Hormuz and the Red Sea

110,000b/d

Barrels per day of Middle East diesel exports to Europe through September 21, down from 191,000 b/d in August and the lowest since February 2020.10 Before the war, about 900,000 b/d of diesel—roughly 10% of global diesel trade—passed through Hormuz (Hana Securities).11

RUSSIA

Refineries hit by drones

140,000b/d

Barrels per day of Russian diesel shipments in Q3, down 500,000 b/d year on year. Nearly half of refining capacity was offline by late September (S&P Global CERA). Diesel exports had been banned since July, with the ban extended to end-October.8 On October 10, Russia partially eased the ban, initially allowing 500,000 tonnes of overseas supply.12

CHINA

Export permits, issued month by month

3.7mtonnes · Three fuels combined

China's approved October exports of diesel, gasoline and jet fuel combined (re-authorized October 9). This is not a diesel-only figure. Analysts estimate jet fuel will account for about 60% of October exports, with gasoil at roughly 900,000 tonnes (S&P Global).13, 14 Hana Securities describes the amount as 20% below August, apparently comparing approved October volumes with August customs exports of 4.58m tonnes—a potentially inconsistent basis. China is approving shipments monthly rather than through an annual quota. Hana also notes that commercial diesel inventories are 20m barrels below pre-war levels, which could constrain November exports.11

MAINTENANCE SEASONU.S. refineries enter maintenance season

U.S. refiners are the obvious candidates to help fill the shortfall, but spare operating capacity is limited. Refinery utilization reached 98% in late August, the highest since 2018 (Hana Securities, Sept. 7), before falling toward 92% as autumn maintenance began.11, 15 Utilization can recover as maintenance ends. The question is how quickly—and whether G7 efforts to coordinate maintenance actually add production. U.S. distillate inventories totaled 105.14m barrels in the week ended October 2. A September 18 figure cited by the EPA in its October 5 Texas fuel waiver was about 12% below the five-year average; the agency's letter judged recovery unlikely before early 2027.16 East Coast stocks (PADD 1) were 32% below the 2021–25 September seasonal average, and EIA expects them to remain 20–30% below normal through winter.17

Over the past six weeks, the U.S. exported 1.33m–1.76m b/d of distillates. The four-week average of 1.56m b/d was equivalent to about 40% of domestic distillate product supplied (Snowshagal calculation). Reports in late September said export restrictions were under consideration, but18 on October 2, following the G7 agreement, President Trump said the U.S. would not impose an export ban.19 As long as exports continue, U.S. buyers compete with Europe and Latin America for the same supply.

SEASONAL CONTEXTA seasonal pattern, not a forecast

Hana Securities, using Petronet data, finds that average diesel refining margins over 2011–25 (region unspecified) bottom around week 34 in late August and rise through week 46 in mid-November. Seasonal refinery maintenance, harvest demand and winter heating-oil stockbuilding are offered as explanations.11 The average excludes the crisis years 2022–23 and is not a U.S. benchmark. With war, sanctions and physical refinery damage at play this year, it is context—not a timetable to trade on.

Four Policy Moves Before the Vote

Over two weeks from late September, Washington, the G7 and Russia put forward four sets of measures. New refinery output, barrels drawn from stocks, supply diverted between destinations, and changes to fuel-use rules or tax payments work in different ways—and call for different tests of success. We judge them not by the barrels announced but by whether shipments, inventories and like-for-like product prices actually change.

Five channels through which policy can affect fuel pricesSome measures can move prices without adding production · Channel definitions and monitoring indicators: Snowshagal
ChannelWhat changesPolicy measureWhat to check
New productionActual output of refined productsG7 coordination of refinery maintenance and temporary utilization increases; DOE Strategic Petroleum Reserve crude exchange (to keep crude inputs flowing)Refinery utilization; distillate production
Reserve releasesAdditional stockpiled barrels reaching the marketG7/IEA release of up to 100m barrels of oil and products, prioritizing dieselActual releases by member countries; European diesel premium
Trade diversionSupply available in particular regionsPartial easing of Russian export ban; OFAC GL135; U.S. export ban (on hold)Russian contracts, shipments and arrivals; U.S. distillate exports
Looser fuel-use and distribution rulesBroader permissible uses of existing fuel stocksRelaxed road-use penalties for dyed diesel; EPA Texas sulfur-specification waiverRegional retail prices and inventories
Taxes and cash flowAmount due now and timing of paymentDeferral of the 24.4-cent-per-gallon federal diesel excise tax, subject to Treasury determinations and implementing guidanceTax-inclusive retail prices

These are proposed channels, not proof of an impact · European stock releases could reduce the pull on U.S. exports without reaching U.S. ports · Conversely, a U.S. export ban would not redirect every restricted barrel into the domestic market

The U.S. authorized the sale, transport and import of Russian diesel through April 7, 2027, under OFAC General License 13520 · Russia partially lifted its own diesel export ban on October 10, initially permitting 500,000 tonnes of overseas supply12
Volume
Deputy Prime Minister Novak's plan: 300,000 tonnes in October, 500,000 in November, 1m in December, and potentially up to 3m tonnes per month thereafter12 · The same broad figures as President Trump's October 9 announcement8 · On October 12, Novak projected monthly exports could recover to 3m–3.5m tonnes, roughly pre-crisis levels, by year-end21
Before Nov. 3
Only the October tranche has much chance of reaching the market before the vote. Permits, plans, contracts, loadings and arrivals are different figures; the share destined for the U.S. is unknown
Limitations
Russian refining capacity has been damaged. If the measures merely redirect existing exports, net additions to world supply may be limited (Eugene Investment & Securities)5
Legal / political
The G7's October 2 statement explicitly maintained sanctions on Russia,22while Washington granted a Russian-diesel exemption on October 9. On October 11, seven senators—four Republicans and three Democrats, including Senate Foreign Relations ranking member Jeanne Shaheen—called for its withdrawal, arguing it conflicted with the 2022 ban on Russian energy imports23. On October 13, 12 senators, including Richard Blumenthal (six Republicans, six Democrats), wrote to the president seeking to rescind the agreement and OFAC GL135. Five signed both appeals, leaving 14 distinct senators24. Representative Brian Fitzpatrick (R) had said on October 10 that he would propose import-blocking legislation and seek a procedure to force a vote25. Legal and policy uncertainty hangs over contracts, shipments and customs clearance for U.S.-bound cargoes
CHANNEL · Trade diversion
G7OCT. 02 · LEADERS' STATEMENT

Up to 100m barrels from reserves, plus refinery coordination

What changes
A G7/IEA release over four months of up to 100m barrels of crude and refined products, with a “substantial” quantity of diesel in the first 20 days. Members would coordinate maintenance to avoid simultaneous refinery shutdowns, temporarily raise utilization where possible and cooperate with major refining nations. The G7 also agreed to avoid energy export restrictions among members22
Volume
The crude/diesel mix was not disclosed. JPMorgan and a European diplomat said much of the volume may be unfulfilled commitments from March's IEA release26, 27 · Even previously pledged stocks are new market supply if they have not yet been released
Before Nov. 3
The initial 20-day diesel priority window runs to around October 22. The releases would largely serve Europe, but could reduce European demand for U.S. products
Limitations

EOSIGNED OCT. 05 · EXECUTIVE ORDER

Dyed-diesel restrictions and tax-payment relief

What changes
Executive Order 14435 directed measures to defer federal diesel excise-tax payments and relax penalties for using tax-exempt, red-dyed off-road diesel on public roads from October 5 through December 31. Eligibility, scope and feasibility depend on Treasury determinations under the law and subsequent IRS guidance28, 29 · Separately, an EPA Texas waiver allowed use of diesel containing up to 500 ppm sulfur through October 24, subject to restrictions including engine compatibility16
Volume
No new fuel is produced. The measures expand which existing fuels can be used within the refining and distribution system
Before Nov. 3
The federal 24.4-cent levy is equivalent to about 4% of the $6.199 retail diesel price (Snowshagal calculation). That is the tax amount as a share of the pump price—not a forecast price cut. This is deferral, not exemption (which Treasury was asked to consider separately), so actual savings and pass-through to consumers are uncertain. State rules on dyed diesel also vary29
Limitations
The measures do not create new refining capacity (Tom Kloza, cited by CBS)29 · They may change the usable fuel pool and when buyers pay
CHANNEL · Use restrictions + tax deferral
BANSEPT. 28 REVIEW · OCT. 02 SHELVED

Diesel export restrictions

What changes
Limits on overseas sales of U.S.-produced diesel. Reports said the idea was being considered on September 28,18 and Hana Securities interpreted it as leverage to press Europe to release reserves11. On October 2, President Trump said the U.S. would not pursue an export ban19
Volume
U.S. distillate exports averaged 1.56m b/d over four weeks, equivalent to roughly 40% of domestic distillate product supplied (EIA; Snowshagal calculation)15 · A ban would not divert the entire volume to U.S. consumers
Before Nov. 3
The proposal is on hold. The G7 statement also discourages export restrictions among members22 · Revival of the proposal remains a separate risk
Limitations
If imposed, a ban could disrupt European and Latin American supply. In one Eugene Investment & Securities scenario, U.S. inventories rise, refinery utilization falls and lower gasoline output drives gasoline refining margins higher5
ON HOLD · Risk of revival

One measure lies outside the four cards. On October 10, the Department of Energy authorized an exchange of up to 4m barrels of crude from the Strategic Petroleum Reserve with ExxonMobil and BP to address Gulf of Mexico hurricane disruptions. Energy Secretary Chris Wright said the move was intended to maintain refinery operations and limit fuel-supply interruptions.30 This would not add 4m barrels of diesel. Its role is to prevent crude feedstock shortages from shutting down refineries.

HOW MANY DAYSHow many days of U.S. demand could Russian diesel cover?

The Russian figures first need a common unit. Announcements are in tonnes, and Deputy Prime Minister Novak's October–December plan totals 1.8m tonnes, broadly matching the figures announced by President Trump.8, 12 Brokerage conversions differ. Eugene Investment & Securities calls 36m barrels “10 days of U.S. consumption”; Hana Securities puts 1.8m tonnes (13m–14m barrels) at “three to four days.”5, 11 Eugene's 36m-barrel figure is close to 4.8m tonnes—the three-month plan of 1.8m tonnes plus a further month at the later maximum of 3m tonnes. Neither firm specifies its demand denominator, so we recalculated using EIA's four-week average of distillate product supplied, a proxy for U.S. demand.

The October–December plan of 1.8m tonnes equals about 3.6 days of U.S. distillate demand

CALCULATION Tonnes × 7.5 barrels/tonne (the same conversion factor used by Eugene Investment & Securities) ÷ four-week average U.S. distillate product supplied (3.77m b/d, weeks ended Sept. 11–Oct. 2) · Announced plans as of Oct. 10, not contracted, loaded or landed volumes · U.S.-bound allocation unknown · Distillates include heating oil; EIA product supplied is used as a demand proxy · A 30-day distribution is illustrative · Snowshagal calculation

The October–December plan of 1.8m tonnes represents roughly 3.6 days of estimated U.S. distillate demand. Adding one month at the later 3m-tonne maximum raises the comparison to 9.6 days. This indicates scale, not a price effect. For illustration, spreading 13.5m barrels over 30 days gives 450,000 b/d—about 29% of U.S. distillate exports of 1.56m b/d (Snowshagal calculation). The actual impact depends on arrival rates, destinations and how much of the volume displaces existing supply. On October 12, Novak additionally projected that Russian monthly exports might recover to 3m–3.5m tonnes by year-end.21 That is a forecast of monthly export recovery, not contracted or shipped volumes. The chart therefore uses the October 10 plan.

04 · THE COUNTERCASE

The Case That Prices Have Peaked

Risks still in play before the election · Gulf of Mexico hurricane · Strait of Hormuz · Attacks on refineries · Illustration

There is a substantial case against assuming the squeeze lasts through Election Day. Pump prices have fallen for two consecutive weeks, and crack spreads initially eased following the announcements. Some policies also target refinery operations. The question is whether falling prices are accompanied by actual implementation and a recovery in output.

COUNTERARGUMENT 1 · Prices are already falling

EIA's weekly diesel price fell 5.1%, from $6.529 on September 21 to $6.199 on October 5. The decline from the peak was 3.8% using AAA's daily series (cited by Eugene Investment & Securities).3, 5 Weekly pump prices began falling in the week of September 28, before the G7 agreement (Oct. 2), dyed-diesel order (Oct. 5) and Russia measures (Oct. 9–10). On the day of the G7 announcement, Europe's diesel premium to crude briefly fell to $69/bbl, from $76.77 the previous day. The NYMEX crack spread fell $6.45 intraday on the Russian-diesel news.8, 26

But weekly closing prices tell a different story by region. Converting European diesel from tonnes to barrels at 7.45 barrels/tonne, its premium over Brent rose from roughly $80 at the October 2 close to $94 at the October 9 close (Snowshagal calculation; not the same basis as the intraday quotation above).6 Asian gasoil spot prices fell 2.6% over the same week (Petronet data).5 With Russia's measures announced October 9–10, it is too early to judge them using those weekly closing prices. U.S. diesel futures also rebounded by about 5% on October 13.32 It is premature to say Russian supply authorization has stabilized product prices. The futures move is in the outright diesel price, however; it does not imply a comparable increase in the crack spread.

COUNTERARGUMENT 2 · Fourth-quarter cracks may narrow

Daishin Securities expects additional diesel supply to compress fourth-quarter gasoil crack spreads. From the perspective of Korean refiners, it anticipates better-than-expected Q3 results but contrasting inventory and crack-spread effects between Q3 and Q4.27 EIA also expects crack spreads to ease but remain historically elevated, with retail diesel staying above $6/gal in October. Its baseline was prepared using information through October 1, before the G7 and Russian measures. EIA forecasts annual average diesel pump prices of $5.19/gal in 2026 and $4.49 in 2027.17

COUNTERARGUMENT 3 · Policy does reach the refining stage

The G7 statement goes beyond reserve releases: it calls for coordinating refinery maintenance and temporarily increasing utilization,22while the DOE's SPR exchange aims to keep crude inputs flowing and refineries running.30 Russia, meanwhile, partly lifted its diesel export ban on October 10.12 It is not that refining has been ignored. The scale and timing of any additional production and cargo arrivals are simply unverified.

Hana Securities views the measures as stopgaps and expects replenishment demand to keep refining margins firm. Eugene Investment & Securities argues that high diesel-led margins will persist until war-damaged refining capacity is restored.5, 11 Retail prices have fallen, but product futures rebounded on October 13 and there is not yet a confirmed turn in inventories or capacity data.

05 · INFLATION

Gasoline in CPI,
Diesel in the Supply Chain

Diesel's direct weight in U.S. consumer inflation is far smaller than gasoline's. The bigger route into prices runs through freight costs. September CPI, released October 14, showed inflation pressures that predated the policy announcements; any effect of the October measures must be assessed from subsequent product prices and inventories.

DIRECT WEIGHTA small direct weight

In the August CPI detailed tables, gasoline represented 3.770% of the index on a July 2026 relative-importance basis. Motor diesel falls under “other motor fuels” (0.112%), while heating oil appears under “fuel oil” (0.107%).41, 42 “Other motor fuels” is broader than diesel: it also covers ethanol blends, biodiesel, natural gas and electricity for vehicles. The two CPI categories together carried 0.219%—about one-seventeenth of gasoline's weight. Because relative importance shifts with prices, their combined weight increased from 0.169% in December 2025 (when gasoline was 2.895%).43

INDIRECTThe indirect route: freight and airfares

In August's Producer Price Index, diesel rose 24.1% month on month; truck transportation rose 2.0%, and transportation and warehousing services 2.3%.45 Higher freight rates may feed through to food and goods prices with a lag. September PPI is due October 15.46

Airfares are another services category exposed to fuel costs. Jet fuel comes from the same middle-distillate family as diesel. CPI airfares rose 23.4% year on year in August.47 But demand and seat capacity also affect fares, so the full increase cannot be attributed to fuel.

OCT 14 · 21:30 KSTOctober 14: Expectations versus the release

Daishin Securities' Bloomberg consensus figures called for September headline CPI of 3.6% YoY and core CPI of 2.5%, up from August's 3.4% and 2.4%. The firm cited September diesel prices as part of the pressure (EIA average retail diesel: $6.29/gal).17, 46 Month-on-month expectations were 0.6% for headline and 0.2% for core (as compiled by FinancialJuice; survey provider unspecified).48

The actual September headline reading was 3.7% YoY, 0.1 percentage point above consensus. Monthly inflation was 0.6%, in line with expectations. Gasoline did most of the work on headline inflation. Gasoline rose 9.1% during the month, accounting for more than half of the overall monthly gain, and was up 34.2% YoY. Other motor fuels (which include diesel) rose 60.9% YoY and fuel oil 74.2%, versus 44.0% and 52.0% in August. Their smaller weights meant less impact on the headline number than gasoline.44

Core CPI also beat expectations, rising 2.6% YoY and 0.3% month on month—each 0.1 percentage point above consensus. Shelter costs rose 0.4% on the month, and airfares also increased.44 With core inflation above expectations as well, this was not solely an energy-price story. The release does not, however, isolate how much diesel-driven freight costs contributed to core CPI.

September CPI is not a report card on October's measures. Its 3.7% YoY reading comes from September prices, before the policies announced from October 2 onward. That is separate from its political significance as the last CPI release before the midterms.

The Diesel Story, Seen from Ulsan

Illustration of a petroleum-products tanker leaving a refinery port at sunset, with its dotted route extending toward the horizon
From Ulsan to Europe · About 670,000 barrels of Korean diesel were being exported to Europe in September (roughly 20,000 km, a four-to-five-week journey; Hana Securities, Sept. 7) · Illustration

The U.S. diesel squeeze reaches Korean markets through three channels. For refiners, it is the gap between realized product sales prices and crude acquisition costs. For airlines, it is the cost of jet fuel translated into won. For interest rates, the path runs through U.S. inflation. A lower crack spread does not automatically hurt refiners and help airlines.

EXPORTSExport growth driven by prices, not volume

According to the Ministry of Trade, Industry and Resources' September trade report, Korea exported $7.22bn of petroleum products, up 72.0% year on year. Volumes fell 6.9% to 5.7m tonnes, while the unit price jumped 84.7% to $1,267/tonne. Dubai crude averaged $113.71/bbl that month, up 62.4%.50, 51 This was a price-led increase, not a volume boom: Korea shipped similar or smaller quantities at far higher unit values. Exports to the EU rose 241.8% during September 1–25. Media reports linked this to local jet-fuel inventory shortages, but that was not an official explanation from the ministry.51 Higher export prices do not translate directly into refiner profits. Crude acquisition costs, freight and operating expenses also matter.

How to read the gauges

  1. If only pump prices fallFalling retail diesel with an unchanged crack spread and inventory shortfall may mostly reflect lower crude prices. That is not enough to establish relief in the product bottleneck
  2. Signs that the bottleneck is easingOn a consistent basis, the New York Harbor monthly spot crack falls from September's $110.8, while inventories close their gap to the five-year average for the same week · The post-war March–August average crack of $73.9 is context, not a threshold
  3. The biggest supply-side swing factorActual Russian diesel shipments under the authorization and confirmation of an “energy truce” by Moscow. Repairs to damaged refinery capacity could still take months

DistillatesAn EIA statistical grouping encompassing diesel and heating oil, used to report inventories, consumption proxies and exports.
ULSDUltra-low-sulfur diesel with a sulfur content no higher than 15 ppm; the standard specification for U.S. on-road diesel.
Dyed dieselTax-exempt diesel for off-road applications, such as farm and construction equipment; dyed red to distinguish it.
Product suppliedEIA's proxy for consumption, calculated as production + imports − exports − increase in inventories.
Complex refining marginA refining margin based on the mix of products produced by a refinery. Hana Securities cites an Asian benchmark.
