HSFO 3.5% FOB ARA Barges rallied 21% open-to-close in July ($402.50 to $488.50/mt), driven by Brent's Middle East-conflict-driven surge to $96.22/bbl rather than any HSFO-specific mechanism; VLSFO was the only NWE grade to gain on a monthly-average basis, and the HSFO discount to Brent deepened to -$19.29/bbl as the product lagged crude. The curve structure steepened (M1-M12 backwardation widening to $61.00/mt) while the Hi-Lo spread held above the $100/mt threshold all month, and East-of-Suez bunker tightness pulled ARA's discount to Singapore back out to -$65.71/mt by month-end. Trading activity nearly doubled to 300+ trades on a 1.5:1 buy-side skew, with TOTSA TotalEnergies jumping from single digit sell-side trades in June to over 120 trades in July, a producer offloading into strength rather than routine hedging. None of this month's moves are HSFO-specific: continued Hormuz/Red Sea escalation should keep the crack deep, the curve steepening, and the lighter grades in the lead.
MARKET ACTIVITY
- The window ran 554 bids against 378 offers, and 320 trades cleared against June's 167, so the rally pulled participants in rather than driving them out
- Oil-major buying led the bid stack, with BP Netherlands, ExxonMobil Asia Pacific and Shell Trading Rotterdam together accounting for the bulk of named buy-side activity; as refiners and bunker suppliers that is demand coverage, restocking into a rising price, and it is consistent with East-of-Suez tightness spilling into European coverage buying
- Bunker resellers United Bunkers and Northstar sat behind them, adding delivered-stem replenishment rather than discretionary length
- Trade houses bought too but in materially smaller size, so the bid was built on physical coverage rather than intermediary appetite
- The sell side was led by trade house Vitol and oil major TOTSA TotalEnergies in near-equal size, with producer/NOC Aramco Trading third
- The regime change is TOTSA, which sold in two trades in June and 123 in July to become the window's second-largest seller; a major refiner ramping offer pace that hard into a Brent-driven rally reads as producer offloading into strength, not the routine hedging flow of a quieter month
- Glencore traded both sides, which is intermediary positioning rather than directional flow

CROSS-MARKET DYNAMICS
- HSFO crack vs Dated Brent opened -$5.38/bbl, closed -$19.29/bbl; monthly avg -$10.07/bbl vs June's -$9.12/bbl (-10.4% MoM, deeper). This sits mid-range within the trailing 13 months (shallowest Oct-25 at -$2.76/bbl, deepest Apr-26 at -$28.11/bbl)
- The deepening reflects the driver, not a heavy/sour-specific squeeze: Brent's Middle East-conflict rally (open $68.77/bbl to close $96.22/bbl, +39.9%) outpaced HSFO's own gain, so the crack compressed rather than expanded
- VLSFO was the only grade with a positive MoM average and the only one to outright rank first on both price level and MoM change; the quality ladder held (0.5% > 1% > 3.5% throughout)
- 1% sulfur fuel oil (LSFO) fell hardest on a MoM basis (-5.01%) despite rallying intramonth from $443.75/MT (open) to $523/MT (close, +17.9%); a weak first week dragged its average down more than either of the other two grades, so the ranking by MoM average understates how strongly all three grades finished the month
- Hi-Lo spread (VLSFO minus HSFO) opened $133.00/mt, closed $148.50/mt, avg $125.54/mt; narrowest print $108.50/mt (20-Jul), widest $148.50/mt (31-Jul, also the monthly high). The spread never traded below the ~$100/mt watch level in July; a sustained hold above that level reinforces scrubber-fitted vessel demand for HSFO, a demand-side factor layered on top of the crude story
- June's spread told a different story: it opened at $59.75/mt before widening to $131.75/mt by month-end as HSFO sold off harder than VLSFO into the June close
CROSS-REGIONAL DYNAMICS
- ARA held at a discount to Singapore all month; the discount narrowed on average from -$40.26/mt (June) to -$32.89/mt (July), but the intramonth path reversed sharply: it nearly closed to +$2.27/mt on 7-Jul before widening back to -$65.71/mt by 30-Jul and -$47.42/mt at the close
- Mechanism: East-of-Suez HSFO and VLSFO availability tightened through July (Fujairah HSFO lead times extended to 12-15 days from 9-13; Singapore VLSFO lead times to 16-20 days from 14-19) as Gulf disruption cut regional supply; Singapore absorbed extra fuel oil arrivals from Brazil and Russia to offset the shortfall, bidding Singapore cargoes up relative to ARA in the back half of the month
- ARA-USGC flipped from a -$52.79/mt discount in June to a +$4.43/mt premium in July (open -$18.70/mt, close +$21.52/mt, widest premium +$43.30/mt on 30-Jul); no verified driver identified for this reversal, flagged rather than attributed

SOMETHING TO WATCH
- Hi-Lo spread and the scrubber-demand feedback loop:
- Observation: Hi-Lo closed July at $148.50/mt, holding above the ~$100/mt reinforcing threshold every session
- Why it matters: a sustained Hi-Lo above $100/mt keeps scrubber-fitted vessel demand tilted toward HSFO, a second demand-side prop on top of the Middle East supply story; a drop back toward $80-100/mt would remove that support
- What to monitor: weekly Hi-Lo close; East-of-Suez HSFO lead times; scrubber-fitted vessel bunkering volumes
- Strait of Hormuz / Red Sea transit status as the binary catalyst for the whole complex:
- Observation: Brent closed July at $96.22/bbl, up from $68.77/bbl at the open, on renewed US-Iran strikes and an expanding Houthi Red Sea blockade
- Why it matters: the HSFO rally, the crack compression, the curve's bull steepening, and VLSFO's outperformance are all riding the same crude-linked risk premium rather than a European fuel-oil-specific mechanism; de-escalation would unwind them together
- What to monitor: Strait of Hormuz tanker transit counts; any US-Iran diplomatic signal; Houthi Red Sea blockade status
- M1-M2 spread as the front-led unwind signal:
- Observation: M1-M2 widened from +$2.00/mt to +$9.00/mt in July, while M1-M12 widened over 4x to +$61.00/mt
- Why it matters: a collapse in M1-M2 back toward flat would signal the prompt physical squeeze easing even if the back-end stays elevated on a structural risk premium; continued widening would confirm physical tightness is still building at the front
- What to monitor: weekly M1-M2 close on ICE 3.5% Barges; ARA barge loadings; confirmed resumption of full Gulf-origin flows
