Brent tops $100 as Iran-US tanker strikes escalate diesel crunch

Geopolitics just did what OPEC+ couldn't: send Brent back over $100 for the first time since July, and the fuels market is feeling it unevenly β€” diesel is sprinting, gasoline is losing its grip.

Middle East escalation between the US and Iran, plus strikes on Russian and Saudi energy infrastructure, pushed Brent above $100 and sent ULSD futures up another 15 cents/gal, while RBOB's steep backwardation is unwinding as driving season ends. Diesel is on pace for a record annual average price and retail diesel is holding above $5.97/gal nationally, squeezing truckers and consumers even as refining bottlenecks and looming maintenance season threaten to tighten US fuel supply further. On the policy side, SAF and renewable diesel activity continues apace globally β€” from IRS 45Z guidance to new SAF certification schemes and coprocessing lines β€” while Casey's earnings show fuel retail margins remain a mixed bag for operators.

# CVR Energy (CVI) β€” Refined Fuels Takeaways from Sept 2026 Investor Presentation - **Throughput/utilization**: Total nameplate crude capacity 206,500 bpd (Coffeyville 132,000 bpd + Wynnewood 74,500 bpd, complexity 10.8); TTM throughputs ~215,000 bpd with 97% liquid volume yield and 92% gasoline/distillate yield. Five-year average utilization is 90% (incl. turnarounds); **no planned Petroleum Segment turnarounds in 2026** (next ones: Wynnewood 2027, Coffeyville 2028), implying sustained high run rates through year-end. - **Crack spreads improved sharply but capture rates fell**: Group 3 2-1-1 crack averaged **$33.34/bbl in 1H26 vs. $20.89/bbl in 1H25**, yet CVR's adjusted margin capture dropped to **26% in 1H26 from 46% in FY25**, driven by higher RIN prices, realized derivative losses, and steeper crude backwardation β€” margin capture, not crack spreads, is the bottleneck. - **RIN/SRE exposure remains material**: Company is "diligently pursuing" Small Refinery Exemptions at Wynnewood; SREs granted in Aug 2025 and Aug 2026 would have added ~6% to average margin capture over 2021–2025, underscoring how RFS compliance costs are a persistent drag on realized margins. - **RDU reversion signals hydrocarbon-first stance for now**: Wynnewood's Renewable Diesel Unit has been converted back to hydrocarb

## Casey's General Stores (CASY) β€” Q1 FY2027 10-Q: Refined Fuels Takeaways - **Fuel volume/throughput:** Gallons sold rose 2.5% YoY to 934.2M (from 911.8M), though same-store gallons *declined* 0.3% β€” growth came entirely from net new stores (64 more locations, incl. 12 acquisitions), not underlying demand strength. - **Margin capture β€” historically elevated:** Fuel margin (revenue less COGS ex-D&A) was 47.8 cents/gallon vs. 41.0 cents/gallon a year ago, despite the *percentage* margin compressing to 12.0% of fuel revenue (from 13.7%) as retail price/gallon jumped 33.0%. Management explicitly flags this as "historically higher than average" for the company and industry, cautioning it can swing unpredictably. - **RIN exposure quantified:** Recognized $25.7M from 10.9M RINs monetized in Q1 FY27 vs. $6.7M from 6.1M RINs a year earlier β€” RIN volume/value nearly doubled/quadrupled, but net impact to fuel margin was described as "minimal" since higher RIN revenue was offset by higher RIN-related costs. Company early-adopted ASU 2026-02 (environmental credits), now marking RINs to fair value (Level 1) as noncompliance environmental credits; balances remain immaterial to the balance sheet. - **Wholesale/logistics footprint:** Wholesale fuel activity comprises ~3% of total revenue; Casey's self-distributes the majority of its fuel via its own Waco, TX terminal and continues hedging bulk inventoried fuel (pipeline/terminal) with futures β€” derivative positions remain immaterial as of quarter-end. - **EV build-out still marginal:** Only 294 charging ports across 68 of 2,959 stores (14 of 19 states) β€” company reiterates Midwest EV demand lags coastal markets, signaling no near-term cannibalization risk to gasoline/diesel volumes. - **Capital allocation tilts toward fuel infrastructure/growth:** Capex jumped to $194.4M (from $110.0M) and acquisition spend to $43.9M (from $9.5M) alongside a share buyback program expansion from $400M to $1.0B (Board authorized June 2026), signaling confidence in continued fuel-retail footprint growth even amid normalizing margins. **Signal for fuels markets:** Casey's results reflect a retail fuel margin environment that remains unusually rich (47.8Β’/gal) even as percentage spreads compress with rising pump prices, while RIN monetization is scaling in volume

## Key Takeaways β€” Casey's General Stores Q1 FY2027 (Fuel-Relevant Metrics) - **Fuel margin expansion drove profit growth**: Fuel margin (excluding credit card fees) rose to **47.8Β’/gallon** from **41.0Β’/gallon** YoY (+16.6%), pushing total fuel gross profit up **19.6%** to **$446.9 million** despite roughly flat volumes β€” indicating retail fuel capture/spread strength outpaced volume growth this quarter. - **Same-store fuel demand softened**: Same-store gallons sold declined **0.3%** YoY (vs. +1.7% in the prior-year quarter), though positive on a two-year stack (+1.4%). Total fuel gallons sold still grew **2.5%** to **934.2 million gallons**, driven entirely by net store count growth (64 more stores YoY, including the Fikes acquisition), not underlying demand. - **No renewable diesel/SAF or RIN/LCFS exposure disclosed**: As a fuel retailer (not a refiner or producer), Casey's has no stated renewable fuel production capacity, RIN generation/obligation, or LCFS credit exposure in this release β€” fuel economics here reflect retail marketing spread only, not refining/blending economics. - **Guidance unchanged**: FY2027 outlook reaffirmed β€” same-store fuel gallons expected in a **-1% to +1%** range, consistent with the current quarter's softness; management flagged no shift due to macro fuel demand trends. - **Capital allocation favors expansion over fuel infrastructure specifics**: Store count grew to **2,959** (net +15 in-quarter, including 12 acquired sites), with capex guidance of **~$800 million** for FY2027 and continued M&A-driven growth (target **120+ new stores**), suggesting continued investment in fuel-dispensing retail footprint amid integration of the Fikes acquisition (ahead of schedule per CEO commentary). - **Liquidity/returns steady**: $1.4B available liquidity ($524M cash), $45.6M in buybacks this quarter, $973M remaining authorization, and a raised-looking but flat $0.65/share dividend β€” signaling no acute capital strain tied to fuel margin volatility. **Market signal**: Casey's results show retail fuel marketing margins remain historically elevated even as underlying same-store gasoline demand is flat-to-slightly-negative, reinforcing that convenience-fuel retailers are capturing wider spreads in a volatile wholesale fuel environment rather than benefiting from volume growth β€” a dynamic more reflective of retail margin resilience than refined product demand strength.
