Summary
Dated Brent averaged $125.00/bbl (+7.0% MoM, +93.3% YoY), but the story is the physical premium unwinding under a firm flat price: Dated went from $15.95/bbl over the North Sea Prompt Strip to $0.085/bbl. Hormuz attacks drove the $135.66/bbl peak on 8 Oct; emergency stock releases then split physical from paper, Dated falling $9.80/bbl on 16 Oct while Cash BFOE M1 eased $0.66/bbl. CFD W1-W2 flipped from +$6.95 to -$0.95/bbl while Cash BFOE M1/M3 widened to $7.42/bbl, so the easing sat in in-window cargoes, not the forward curve. Johan Sverdrup led the slide, its diff to the Strip averaging $4.35/bbl vs $13.48/bbl in September as restarted Saudi East-West flows and discounted Aramco cargoes refilled European sour supply. With Saudi November allocations restored and Hormuz decisions pushed past the 3 November US midterms, watch the CFD front and Johan Sverdrup's diff.
Price trends
Dated averaged a 13-month high of $125.00/bbl but closed $8.13/bbl below its open as the in-window premium bled out
- Opened $126.895/bbl (1 Oct), closed $118.77/bbl (30 Oct); average $125.00/bbl vs $116.80/bbl in September and $64.65/bbl in October 2025; high $135.66/bbl (8 Oct), low $114.905/bbl (29 Oct)
- The Strip rose from $110.945 to $118.685/bbl, so Dated's fall was the physical premium compressing, not the forward market selling off
- Largest session: -$9.80/bbl on 16 Oct ($126.405 to $116.605) against -$0.66/bbl on Cash BFOE M1 (December, $106.43 to $105.77) and an unchanged EFP at +$0.07/bbl, so paper and implied ICE Brent futures barely moved; accelerated IEA emergency releases (15 Oct) and a US SPR exchange offer of up to 17 million barrels (16 Oct) added prompt Atlantic supply, hitting in-window cargoes rather than the forward market
| Week | Avg ($/bbl) | WoW | Driver |
|---|---|---|---|
| 1-2 Oct | 126.76 | n/a | September's physical premium carried in |
| 5-9 Oct | 130.25 | +3.49 | Iranian attacks in Hormuz cut Gulf crude flows (Kpler) |
| 12-16 Oct | 126.91 | -3.35 | Emergency stock releases; -$9.80 on 16 Oct |
| 19-23 Oct | 121.41 | -5.50 | CFD W1-W2 first negative (19 Oct) |
| 26-30 Oct | 120.73 | -0.68 | Discounted Saudi barrels into Europe |

Cross-commodity dynamics
Sweet grades held $15.34-16.23/bbl over the Strip while Johan Sverdrup collapsed; the sweet-sour gap widened from $0.09 to $11.80/bbl
| Grade (diff to Strip, $/bbl) | Sep avg | Oct avg | Change |
|---|---|---|---|
| Troll | 13.49 | 16.23 | +2.74 |
| Oseberg | 13.57 | 16.15 | +2.58 |
| Ekofisk | 12.60 | 15.34 | +2.74 |
| Forties | 10.72 | 13.65 | +2.93 |
| WTI Midland FOB North Sea | 9.57 | 11.71 | +2.14 |
| Johan Sverdrup | 13.48 | 4.35 | -9.13 |
Source: GX Go
- Johan Sverdrup's average fell $9.13/bbl while every other grade rose $2.14-2.93/bbl: the 11 Sep East-West pipeline shutdown made it Europe's substitute for Saudi medium sour; the restart around 22 Sep (Yanbu loading about 2 mb/d, Kpler) and discounted Aramco spot offers removed that premium
Market activity
Window trades rose 12% to 546 as offers grew 25%; the bid-heavy book thinned from 1.58:1 to 1.37:1
- 546 executed trades vs 489, led by Brent CFD vs 1st month (366, +45%); offers rose 24.7% vs bids 8.0% as the premium unwound
- Intermediaries led buying (Trafigura 143, from 78; Mercuria 70; Vitol 63); top sellers DV Trading (93), Dare Global (73) and Onyx (70) traded both sides in both months, so this volume is positioning and liquidity, not directional flow
Cross-market dynamics
Freight absorbed the war premium; Brent-Dubai EFS halved to $4.95/bbl
- The implied cost of moving crude to Asia (delivered price minus loading-point price) rose from $10 to $38/bbl between April and October, vs $5 to $13/bbl into Europe (J.P. Morgan)
- EFS averaged $4.95/bbl vs $9.85/bbl in September; with Asia freight near 3x the Europe leg, a narrower EFS alone does not open the east arb, so eastbound Atlantic barrels must clear at deeper FOB discounts
Curve structure
Front collapse in the CFD layer; W1-W2 flipped from +$6.95 to -$0.95/bbl while Cash BFOE M1/M3 widened
| Spread ($/bbl) | Month-Start (1 Oct) | Month-End (30 Oct) | Change |
|---|---|---|---|
| CFD W1-W2 | +6.95 | -0.95 | -7.90 |
| CFD W1-W4 | +15.26 | -1.30 | -16.56 |
| Dated vs Cash BFOE M2 | +28.87 | +5.09 | -23.78 |
| Cash BFOE M1-M2 | +3.78 | +3.80* | +0.02 |
| Cash BFOE M1-M3 | +6.69 | +7.42* | +0.73 |
Source: GX Go
*29 Oct: no December Cash BFOE M1 print on 30 Oct.
- Front collapse: W1-W2 went negative on 19 Oct and W1-W4 on 28 Oct; the prompt cargo week now prices below forward weeks
- Paper did not follow: Cash BFOE M1 rose $12.27 to $114.08/bbl (1-29 Oct), confining the easing to in-window cargoes, where emergency and returning Saudi barrels land first
Price volatility
Flat-price CV halved to 4.68% while Midland and Forties diff swings held at $6.72-7.01/bbl, 3x their summer levels
| May | Jun | Jul | Aug | Sep | Oct | |
|---|---|---|---|---|---|---|
| Dated Brent (CV %) | 6.18 | 12.98 | 12.67 | 2.94 | 9.14 | 4.68 |
| North Sea Prompt Strip (CV %) | 6.07 | 12.40 | 11.32 | 4.09 | 5.76 | 3.70 |
| WTI Midland FOB diff (sd $/bbl) | 0.96 | 0.48 | 2.22 | 1.83 | 5.93 | 7.01 |
| Forties diff (sd $/bbl) | 1.52 | 0.94 | 1.95 | 2.13 | 6.98 | 6.72 |
| Johan Sverdrup diff (sd $/bbl) | 0.89 | 0.64 | 1.73 | 1.58 | 10.09 | 3.94 |

Diff rows show standard deviation in $/bbl; CV is not meaningful where averages sit near zero.
- Dated CV fell from 9.14% to 4.68%, but the $15.87/bbl collapse in its premium to the Strip sat in the diffs and CFDs, which a flat-price hedge does not cover
- Midland and Forties diff sd held at $7.01 and $6.72/bbl vs $0.48-2.22/bbl in May-August; Johan Sverdrup's fell to $3.94/bbl from $10.09/bbl in September as its Saudi-substitute premium drained out
Something to watch
- Saudi medium sour back in Europe:
- Observation: Aramco restored full November term allocations to European refiners; Johan Sverdrup ended at -$0.12/bbl to the Strip (30 Oct)
- Why it matters: a full Saudi programme removes the substitute bid behind Johan Sverdrup's September premium; East-West throughput still below its 5.5 mb/d pre-attack rate (Kpler) is the upside risk for sour diffs
- What to monitor: Johan Sverdrup vs Strip holding below zero; the Forties-Johan Sverdrup gap (October average $9.30/bbl)
- US midterms (3 November) as the Hormuz decision point:
- Observation: US-Iran diplomacy is reportedly paused until after 3 November; Iran says Hormuz could reopen within 4-5 days if the US lifts its naval blockade
- Why it matters: reopening releases Gulf barrels and removes the remaining Atlantic physical premium; escalation rebuilds it, first in the CFD front
- What to monitor: CFD W1-W2 back above zero (-$0.95/bbl on 30 Oct) and Dated vs Strip moving off $0.085/bbl
