Summary
European LPG extended its rally in October 2026, with propane NWE CIF averaging $831.53/mt (+22.4% MoM, +91.6% YoY) and butane $989.33/mt (+28.8% MoM, +114.9% YoY), even as Dated Brent fell from $126.90/bbl to $118.77/bbl open-to-close. Unlike September's crude-led move, the October rally was LPG-specific: the propane crack vs Dated recovered from -$67.84/bbl to -$45.24/bbl. Butane led, closing at $1,144.50/mt, $133.50/mt above naphtha and $89.00/mt above Eurobob, so it priced itself out of both cracker feed and gasoline blending; cracker operator Ineos sold 22 of 32 butane trades. Downstream offered no pull: European cracker run rates averaged about 70%, NWE ethylene spot stood at €1,073/t on 23 Oct (Platts), and polymer buyers pushed for wider 2027 contract rebates, so LPG rallied against weak petrochemical demand rather than on it. Propane's discount to butane widened to -$232.75/mt at close, while its discount to naphtha narrowed to a -$95.35/mt average. Both curves bull-steepened, with butane M1-M2 more than doubling to +$57.50/mt and butane M12 repricing +$183.25/mt. Butane CV reached 9.88%, the highest of the past six months. With butane above both of its outlets, the butane/naphtha ratio and butane M1-M2 are where a demand-led correction shows first.
Market activity
Butane trades rose to 32 from 23; cracker operator Ineos sold 22 as butane priced above naphtha
- Butane NWE: 32 completed trades in October vs 23 in September (+39%).
- Consumer selling: Ineos, a petrochemical cracker operator, sold 22 trades (16 in September). With the butane/naphtha ratio averaging 1.091 vs 0.921, this is length reduction as butane priced out of cracker feed.
- Ineos bought a 28,000 MT naphtha cargo on 6 Oct in the NWE window, the feed it rotates into when butane loses its discount.
- Exxon became the top buyer with 14 trades (2 in September), 12 of them from Ineos. BPOI, September's top buyer, fell to 6 from 11, and TOTSA sold 4 in both months.
Trade data covers completed butane deals only. Propane NWE CIF window activity was not captured (one Europe-tagged propane trade in October).

- Propane CIF NWE (GX0000686) rose from $732.25/mt (1 Oct) to $911.75/mt (30 Oct, monthly high), avg $831.53/mt vs September's $679.53/mt (+22.4% MoM, +91.6% YoY).
- Butane CIF NWE (GX0000687) rose from $802.75/mt to $1,144.50/mt (30 Oct, monthly high), avg $989.33/mt vs $768.41/mt (+28.8% MoM, +114.9% YoY).
- Intra-month range widened to $179.50/mt for propane (September $111.75/mt) and $341.75/mt for butane (September $132.25/mt), 2.6x.
- Propane fell 4.5% WoW in W4, including the month's largest daily loss of -$52.25/mt on 16 Oct ($867.75 to $815.50/mt), while butane gained 5.9% the same week: the reversal was propane-specific, not complex-wide.
- Largest daily gains: propane +$45.00/mt on 8 Oct ($821.50 to $866.50/mt); butane +$55.50/mt on 23 Oct ($1,039.50 to $1,095.00/mt). Naphtha rose $40.00/mt and $41.75/mt on the same two days.
Cross-market dynamics
Butane priced above both naphtha and Eurobob; the propane-butane discount widened to -$232.75/mt
- Propane crack vs Dated Brent (GX0011245) averaged -$57.94/bbl vs -$62.00/bbl in September, recovering from -$67.84/bbl (1 Oct) to -$45.24/bbl (30 Oct) as Dated fell $8.13/bbl; LPG, not crude, carried October's rally.
- Butane/naphtha ratio (GX0000749) rose from 0.975 to 1.163 open-to-close, averaging 1.091 vs 0.921. Butane-naphtha (derived) flipped from -$75.51/mt (September avg) to +$62.44/mt, closing at +$133.50/mt, triggering September's parity watch item: above parity, flexible crackers switch away from butane.
- Eurobob's premium over butane (GX0000739) collapsed from +$443.50/mt to -$89.00/mt open-to-close (avg +$171.27/mt vs +$494.11/mt). With butane above gasoline, blending lost its economics too, so neither outlet was pulling the butane price higher.
- Propane-butane discount (GX0000738) widened from -$88.88/mt (September avg) to -$157.80/mt, widest at -$255.75/mt and closing at -$232.75/mt; propane is now the cheapest LPG feed by a wide margin.
- Propane-naphtha discount (GX0000736) narrowed from -$164.39/mt to -$95.35/mt avg, closing at -$99.25/mt; propane remains the discounted feed, but $69.04/mt less so than in September.
- Physical premium over swaps (GX0000737) averaged +$38.69/mt vs +$24.85/mt, peaking at +$53.50/mt; physical cargoes led paper.
- Coaster premiums over CIF cargoes widened again: propane FOB coasters (GX0011394) averaged +$79.04/mt vs +$31.25/mt in September, closing at +$87.00/mt; butane coasters (GX0011395) averaged +$160.01/mt vs +$30.91/mt, closing at +$109.25/mt, extending the inland restocking premium flagged in September.
- Downstream petrochemicals: European cracker run rates averaged about 70% in October, held down by weak polymer demand and high costs (Chemical Week). With propane up 24.5% and butane 42.6% open-to-close, crackers had little margin to absorb higher LPG, in line with Ineos selling butane length.
- Olefin prices lagging feedstock compressed both naphtha- and LPG-based cracker margins.
Cross-regional dynamics
NWE propane outran Asia and the Middle East; NWE's premium to ME CP reached +$219.50/mt
- NWE propane (+22.4% MoM) outpaced FE CFR (GX0000874, +11.4% to $978.33/mt avg) and ME CP (GX0000878, +5.5% to $725.49/mt avg).
- NWE-FE discount narrowed from -$198.62/mt (September avg) to -$146.80/mt avg, but closed back at -$200.50/mt as FE CFR rose $206.75/mt open-to-close vs NWE's $179.50/mt; the late widening restores the pull on US cargoes eastward.
- NWE-ME CP flipped from -$8.19/mt (September avg) to +$106.04/mt, closing at +$219.50/mt as ME CP fell from $710.00/mt to $692.25/mt; at that premium NWE outbids the Gulf FOB value, incentivising Middle East cargoes west where freight allows.
Curve structure
Bull steepening on both curves; butane M1-M2 doubled and its back end repriced +$183.25/mt
| Propane | Month-Start | Month-End | Change |
|---|---|---|---|
| M1-M2 | +$22.00 | +$34.50 | +$12.50 |
| M1-M6 | +$121.75 | +$199.50 | +$77.75 |
| M1-M12 | +$165.00 | +$265.75 | +$100.75 |

| Butane | Month-Start | Month-End | Change |
|---|---|---|---|
| M1-M2 | +$27.25 | +$57.50 | +$30.25 |
| M1-M6 | +$123.50 | +$202.75 | +$79.25 |
| M1-M12 | +$159.25 | +$243.75 | +$84.50 |

- Bull steepening: propane M1 (Nov-26) +$203.50/mt vs M12 (Oct-27) +$102.75/mt (2.0x); butane M1 +$267.75/mt vs M12 +$183.25/mt (1.5x).
- Butane M12 rose 28.9% ($635.00 to $818.25/mt), adding back repricing to the steepening: the market priced butane tightness beyond the winter prompt, not only in it.
- Butane M1-M2 stepped up from mid-October, peaking at +$58.25/mt (26 Oct); propane M1-M2 ranged from $21.50/mt (22 Oct) to $36.25/mt (29 Oct).
- M1 rolled to Nov-26 from September's Oct-26, so month-start levels differ from September's month-end table.
Price volatility
| CV (%) | May-26 | Jun-26 | Jul-26 | Aug-26 | Sep-26 | Oct-26 |
|---|---|---|---|---|---|---|
| Propane | 5.58 | 11.10 | 4.49 | 5.89 | 4.86 | 5.30 |
| Butane | 9.26 | 8.89 | 5.79 | 6.44 | 4.88 | 9.88 |
Source: GX Go
- Butane CV doubled to 9.88% from 4.88%, the highest of the six months; with no down week, the dispersion measures a one-way climb from $802.75 to $1,144.50/mt rather than two-way risk.
- Propane CV rose to 5.30% from 4.86%, under half June's 11.10%; its W4 reversal (-4.5% WoW) was the two-way move butane did not have.
Something to watch
- Butane priced above both outlets:
- Observation: butane/naphtha ratio at 1.163 and Eurobob-butane at -$89.00/mt at close; Ineos sold 22 butane trades.
- Why it matters: above parity crackers rotate to naphtha and propane, and blenders cut butane; a ratio back below 1.00 would confirm the premium has unwound.
- What to monitor: GX0000749 and GX0000739 weekly closes; Ineos on the butane sell side.
- Butane prompt vs deferred:
- Observation: butane M1-M2 at +$57.50/mt, M12 up $183.25/mt in the month.
- Why it matters: if the tightness is prompt-only, M1-M2 compresses first; if M12 holds, the market has repriced the whole winter.
- What to monitor: weekly butane M1-M2 and M1-M12 closes.
- Propane relative value:
- Observation: propane-butane at -$232.75/mt; NWE propane +$219.50/mt over ME CP.
- Why it matters: propane is the cheapest LPG feed for crackers, and a wide NWE premium over Gulf FOB draws Middle East cargoes west.
- What to monitor: GX0000738 weekly close; Aramco November CP; NWE-FE vs the -$200/mt month-end level.
