Dated Brent (GX0000968) collapsed from a $107/bbl May average to $85/bbl in June (-21% MoM), closing the month at $72/bbl as the Strait of Hormuz reopening deal unwound the scarcity premium built up since the war's February 28 closure of the strait. The unwind hit the front of every Brent structure hardest: Cash BFOE M1/M3 backwardation flipped from +$5.38/bbl to -$0.61/bbl (last print, 29-Jun), Dated traded to a $2.06/bbl discount to M2 having opened the month at a $5.86/bbl premium, and the CFD curve (W1-W4) flipped from +$1.28/bbl backwardation to -$0.80/bbl contango, a clean front collapse.
Basket diffs to the North Sea Strip compressed across the board, with Forties and Brent Ninian Blend flipping from premiums to discounts by month-end while Johan Sverdrup was the lone grade to hold and widen its average premium. Brent-Dubai EFS narrowed from +$8.04/bbl to +$3.05/bbl, consistent with Gulf-origin barrels re-entering the market as the strait reopened and easing the premium North Sea grades had commanded as substitute supply. Market activity confirmed the regime change: Cash BFOE and weekly CFD flow both ended June net seller-favoured, though the Cash BFOE tilt narrowed to near-balanced by month-end.
Market Activity
- Physical cargo buy/sell ratio was 0.26 in June (56 trades) versus 0.92 in May.
- BP remained the top physical seller (21 trades) versus Glencore Energy UK in May (18).
- Cash BFOE Forward for full June: 151 trades, buy/sell ratio 0.91 (103 buys, 113 sells) - still net seller-favoured.
- Mercuria Energy Trading SA led June selling (37 trades); Glencore Commodities Ltd. led June buying (29 trades); Vitol SA held at 10 buys for the month, consistent with a length-reduction stance rather than fresh buying into month-end.
- Weekly CFD activity for full June: 1,772 transactions, buy/sell ratio 0.80 (927 buys, 1,158 sells).
- Dare Global Limited ran both sides across May and June (buy 208→298, sell 187→193), the clearest financial/market-maker liquidity-provision signature on the desk; DV Trading LLC (159 buys, 117 sells) and Trafigura Pte Ltd (114 sells) were the next-most-active participants.
Price Action
- Dated Brent opened $99.92/bbl (1-Jun), closed $71.52/bbl (30-Jun), monthly average $85.38/bbl vs May's $107.54/bbl (-$22.15, -20.60% MoM).
- YoY the average is still +19.50% vs June 2025's $71.45/bbl, reflecting the residual war premium; the close ($71.52) and June 2025's close ($67.96) are far closer (+5.24%), pointing to a near round-trip in flat price.
- Largest single-day move: -7.11% on 12-Jun ($95.20 to $88.43), ahead of the deal; the only material up-day was 1-Jun (+7.02%), a residual spike on lingering war risk before the de-escalation took hold.
Cross-Market Dynamics
- WTI Midland vs Forties (GX0016422) moved from -$1.355/bbl (1-Jun) to +$0.91/bbl (30-Jun), a $2.27/bbl swing, as Forties' diff to the Strip collapsed harder than Midland's, shifting the marginal-cargo role in the basket back toward Midland.
- Ekofisk vs Johan Sverdrup (GX0016421) flipped from +$1.64/bbl to -$1.12/bbl (-$2.76/bbl), confirming Johan Sverdrup firmed against another basket peer, not just against the Strip average.
Cross-Regional Dynamics
- Brent-Dubai EFS (GX0000585) narrowed from +$8.04/bbl (2-Jun) to +$3.05/bbl (30-Jun), a $4.99/bbl move, against a May-end reading of +$6.65/bbl.
- The narrowing lines up with the approved driver: as the Strait of Hormuz reopening deal took effect from mid-June, Persian Gulf flows began normalising, reducing the relative scarcity value Atlantic Basin and North Sea barrels had commanded.
- This is consistent with the simultaneous compression in Forties' and BNB's diffs to the Strip: the bid for North Sea cargoes as a substitute light-sweet barrel eased as the alternative supply path reopened.
Curve Structure
- Front collapse: every named prompt-tightness gauge in the Brent complex flipped from backwardation to contango within the month; the largest single move was Dated-vs-M2 (-$7.92/bbl), the clearest signal the physical cargo market went from bid-relative-to-paper to discount-to-paper.
- CFD outrights fell hardest at the front (W1 -$24.97/bbl) and least at the back (W4 -$22.89/bbl), the mechanical signature of a front-led unwind rather than a parallel flat-price shift.
- Implication: a sustained contango at the front activates floating-storage cash-and-carry economics; a snap back to backwardation would signal the Hormuz de-escalation is being questioned again.
Price Volatility
- Dated Brent's CV rose to 12.98% in June, second only to March's war-onset spike of 13.60%; a falling average price masked rising day-to-day dispersion, not a calm unwind.
- Forties' diff-to-Strip CV hit 126.16% in June as the differential compressed toward and through zero; a CV above 100% on a near-zero mean confirms the spread itself, not just its level, became unstable.
- Implication: hedging the basket on flat-price vol alone would have understated risk; the exposure this month sat in the diffs and the CFD front, both of which moved through sign changes.
Something to Watch
- CFD front and BFOE M1/M3 re-test of backwardation: Observation: CFD W1-W4 ended the month at -$0.80/bbl contango, down from +$1.28/bbl at the start; BFOE M1/M3 last printed -$0.61/bbl on 29-June.
- Why it matters: a deepening contango activates floating-storage cash-and-carry and builds stocks mechanically; a snap back to backwardation would mark the squeeze re-igniting on a Hormuz relapse.
- What to monitor: weekly CFD W1-W2 close; Cash BFOE M1/M3 close once trading resumes.
- Forties, BNB and WTI Midland diffs holding negative versus Johan Sverdrup's resilience.
- Observation: Forties (-$1.10) and BNB (-$1.01) ended June at a discount to the Strip; Johan Sverdrup held +$2.44.
- Why it matters: a continued discount on the grades that most often set Dated signals ample light-sweet supply has returned to the basket; a reversion to premium would indicate the disruption effect has not fully cleared.
- What to monitor: next month's basket loading programme cargo count; Forties and BNB diff to Strip at month-open.
