SUMMARY
NWE CIF Naphtha rose 8.5% MoM and 34.2% YoY to $744.16/MT in July, rallying from a $649.00/MT low (2-Jul, ceasefire-unwind tail) to a $868.50/MT peak (23-Jul) as Hormuz hostilities and a Houthi attack on Saudi tankers in the Red Sea pushed Brent above $100/bbl for the first time in two months. The rally was crude-led: NWE cracks vs Brent Futures and Dated Brent hit their July lows the same day as crude outpaced product, before a partial bounce left both negative at month-end, reversing June's positive close. The East-West spread more than doubled to average $48.66/MT, widening to $108.75/MT on 22-Jul as Asian buyers moved first on the escalation, a day ahead of NWE's own peak. The curve confirmed the mechanism: M1-M12 backwardation widened to $181.75/MT as the front rallied 3.6x harder than the back, textbook bull steepening rather than structural repricing. Market activity turned buy-side heavy (2.45:1 vs 1.39:1) even as a consumer stepped fully away from the bid stack, consistent with squeezed cracking margins. With Brent still tracking the escalation, the forward spreads and the NWE crack remain the clearest signals of whether the disruption resolves or deepens.
PRICE ACTION

- Monthly average $744.16/MT vs June's $685.73/MT (+$58.43, +8.52% MoM) and July 2025's $554.35/MT (+$189.82, +34.24% YoY)
- Opened the month $662.75/MT (01-Jul); closed $796.75/MT (31-Jul), +19.41% open-to-close
- Monthly low $649.00/MT hit 02-Jul, the tail of June's ceasefire unwind; monthly high $868.50/MT hit 23-Jul, the day Brent broke above $100/bbl for the first time in two months
- Intra-month range of $219.50/MT was 3.8x July 2025's $57.75/MT range
- W1 (3 days) averaged $654.83, still absorbing the ceasefire unwind; W2 +4.25% WoW to $682.65 after the 7-8 July escalation; W3 +8.04% WoW to $737.56 following 12-13 July US strikes on Iran; W4 +12.02% WoW to $826.20, peaking 23-Jul on the Red Sea tanker attacks; W5 -5.13% WoW to $783.80, holding within $13/MT of the close, a plateau rather than a retracement
- Largest single-day move was +$50.50/MT (+6.75%) from 28-Jul to 29-Jul, a rebound inside the post-peak consolidation; no specific news catalyst identified for that session
CROSS-MARKET DYNAMICS
- Crack vs Brent Futures (GX0000630) averaged -$0.27/bbl in July vs -$7.82/bbl in June (+$7.55, +96.5% MoM); moved from +$3.29/bbl (01-Jul) to -$3.37/bbl (23-Jul, narrowest), before a partial bounce to -$0.57/bbl at month-end
- Crack vs Dated Brent (GX0011244) showed greater amplitude: averaged -$0.03/bbl in July (+$8.07, +99.6% MoM), moved from +$5.70/bbl to -$8.01/bbl on 23-Jul, and closed the month at -$6.70/bbl, a $10.15/bbl swing from June's +$3.45/bbl close
- Both NWE cracks hit their July lows on the same session Brent broke above $100/bbl for the first time in two months, the clearest evidence that crude-led buying outpaced the product market that day
- LVN vs NWE (GX0020975) averaged $105.04/MT in July vs $95.59/MT in June (+9.9% MoM), peaking $118/MT on 23-Jul before easing to $90/MT at month-end
- N+A Heavy vs NWE (GX0020978) moved further: averaged $76.52/MT vs $50.50/MT in June (+51.5% MoM), also peaking $90/MT on 23-Jul, holding most of the gain into month-end at $80/MT
- Both grade diffs, both NWE cracks, and the Japan CFR benchmark all turned on the same date, confirming a single market-wide inflection point rather than a product-specific move
CROSS-REGIONAL DYNAMICS
- East-West spread averaged $48.66/MT in July vs $20.33/MT in June, +$28.33/MT (+139% MoM)
- Spread flipped from a marginal NWE premium at June's close (-$1.25/MT, 30-Jun) to a $31.25/MT Asia premium at July's close (31-Jul), a $32.50/MT swing
- Widest point $108.75/MT on 22-Jul, a full day ahead of both regions' own individual price peaks (Japan's high and NWE's high both landed 23-Jul): Asian buyers moved first and hardest on the Red Sea escalation, with NWE catching up a session later
- Narrowest point -$4.50/MT on 08-Jul, briefly inverting to a NWE premium as NWE's own sharp reaction to the 7-8 July escalation outpaced Asia that single session, before Asia reasserted the premium for the rest of the month
- The spread held above $30/MT into month-end rather than retracing alongside the NWE crack bounce, suggesting the regional premium is stickier than the NWE-specific crack compression, consistent with Asia pricing a larger share of the ongoing supply-risk premium
CURVE STRUCTURE
- M1 gained $164.75/MT over the month vs M6's $68.00 and M12's $46.00; the front rallied roughly 3.6x harder than the back, textbook bull steepening
- All three tenors widened in the same direction over the same window, consistent with the market pricing acute near-term scarcity around the 22-23 July escalation while treating the disruption as more resolvable further out the curve
- Further escalation or a confirmed Strait closure would be expected to reprice the back independently, shifting the pattern toward back repricing; a continued M1-led move with M12 holding near $595/MT would confirm the disruption is still being priced as temporary
PRICE VOLATILITY

- NWE CIF CV rose to 8.86% in July from 6.75% in June, below March's 14.12% Hormuz-outbreak peak but above every month since April
- Japan CFR CV rose to 11.94%, its highest since March, and above NWE CIF's reading, consistent with the East-West divergence above
- Grade diffs stepped up too: N+A Heavy CV roughly doubled to 12.64% from 6.22%; LVN CV rose to 10.09% from 7.26%
SOMETHING TO WATCH
- Hormuz/Red Sea escalation trajectory:
- Observation: Brent broke above $100/bbl for the first time in two months on 22-23 July after Houthi attacks opened a front beyond the Strait of Hormuz
- Why it matters: further escalation would likely extend the bull-steepening pattern and push NWE cracks deeper negative; a confirmed de-escalation would likely retrace this month's curve widening
- What to monitor: daily Brent price action, Strait of Hormuz and Red Sea transit reports, any confirmed ceasefire or talks announcements
- East-West spread as the regional-risk signal:
- Observation: the East-West spread hit $108.75/MT on 22-Jul, its widest point of the period covered
- Why it matters: a narrowing spread would signal the market views the disruption as symmetric across regions; continued widening points to Asian buyers pricing a disproportionate share of the risk premium, with implications for arb flows
- What to monitor: weekly Japan CFR close vs NWE CIF close; cargo-tracking data on Asia-bound diversions
- NWE crack spread as the margin canary:
- Observation: both NWE cracks closed July in negative territory, reversing June's positive month-end
- Why it matters: sustained negative cracks would squeeze NWE cracking economics, potentially explaining the consumer retreat already visible in July's bid stack; a return to positive would signal the crude-led rally is being absorbed downstream
- What to monitor: daily crack close for both benchmarks; the same consumer's bid presence in August's MOC window
