WTI — Deal Optimism Overrides an Intact Blockade
WTI settled the week at $84.38 USD/bbl on Friday, its lowest since April 17 — a weekly decline of $8.62 — as a sharp late-week reversal reflected confidence that an imminent U.S.–Iran memorandum would end the war and reopen the Strait of Hormuz.
Jun 15
WTI is trading lower at ~$80.32 Monday after the U.S. and Iran reached an initial agreement to end hostilities and reopen Hormuz — a 14-article MOU to be signed Friday in Switzerland (naval blockade lifted within 30 days, Iranian-oil sanctions suspended, Strait reopened within 30 days under Iranian arrangements). Caveats: the nuclear dispute is unresolved, Tehran keeps leverage over the Strait, Netanyahu rejects the Lebanon clause, and full tanker normalization could take 60–90 days.
Pricing continues to track U.S.–Iran developments closely: selling off Tuesday on a reported pause in strikes, reversing Wednesday after fresh strikes near Hormuz and a far-larger-than-expected U.S. inventory draw pointed to physical tightness, then accelerating lower Friday on deal optimism after Washington called off planned strikes late Thursday — even as the naval blockade of the Strait of Hormuz remains intact.
Supply: OPEC at a Multi-Decade Low, Iran Blockaded
OPEC output fell 1.06 million bpd month-on-month in May to 16.13 million bpd, the lowest since at least 2000 and below the COVID-era trough. Iran represented a significant portion of the shortfall, as the Hormuz blockade cut crude and condensate exports to a six-year low. A number of vessels have attempted to bypass the blockade through ‘dark transits’ under disabled tracking, with reported volumes varying widely; while these free previously trapped supply, they do little to restart shut-in Gulf production.
Buyers have continued to source replacement barrels from outside the Gulf, doing so at discounts to Brent as the extreme near-term tightness seen at the start of the conflict relaxed. Russian Urals flipped to a $2–3/bbl discount to dated Brent at Asian ports from a $7–8 premium in April and May, and Saudi Arabia cut its Arab Light selling price to Asia for a second straight month. Term structures have flattened even as inventories fall, with prompt spreads across the major benchmarks easing from ~$2–3 to ~$1–1.50/bbl.
Domestic: A Seventh Straight Draw, Record Exports
U.S. commercial crude inventories fell 7.2 million barrels in the week ended June 5 — a seventh straight weekly draw that left stocks at their lowest since mid-February and ran well beyond the ~4 million-barrel pull expected. Including strategic reserves, U.S. crude stocks have fallen ~79 million barrels since the conflict began in late February, leaving the SPR at its lowest since August 2023. These draws continue to translate into high exports, averaging 10.5 million bpd in May and positioning the U.S. as the world’s largest exporter for a third straight month. The product side remains structurally tight, sustaining elevated diesel and gasoline spreads that keep Gulf refiners running at seasonally high utilization.
Takeaway
The tape is leaning on a deal that isn’t signed. Flat price fell hard on optimism while the blockade, a multi-decade-low OPEC print, and a seventh straight U.S. draw all argue physical tightness — ING flags $120–130 by late July if Gulf flows don’t resume. The relief valve is real, though: eased term structure, a Urals flip to discount, and rebounding Gulf product exports show the acute squeeze is loosening. Watch Geneva and Hormuz transit counts for the next leg.

Canadian Differentials — Oil-Sands Crunch Splits the Complex
Oil-sands disruptions and water issues defined the week — splitting the condensate complex while tightening heavies and synthetic crude.
Heavy rainfall in northern Alberta and a power outage at Cenovus’s Foster Creek and Christina Lake operations curtailed oil-sands output — the outage alone took roughly 10% of Cenovus’s production offline. Reduced throughput cut diluent demand and returned accumulated volumes to market, loosening diluent-grade C5s (PCE NAM, FSPL, CRW), while C5-PEM tightened as a blend substitute for constrained synthetic supply and was lifted alongside SYN. The same event reduced heavy production, tightening WCS through the week; Western Canadian inventories fell to their lowest since 2020, narrowing the WCS–WTI differential.
| Grade | July diff | Note |
|---|---|---|
| SYN (synthetic) | +$4.30 | standout; upgrader supply constrained |
| C5-PEM (sweet) | −$1.30 | tightened as SYN blend substitute |
| C5-PCE (sweet) | −$1.40 | recovered into Friday |
| PSO / CAL (med sour) | −$3.50 / −$3.80 | tightened on the week |
| C5-PCE NAM (diluent) | −$7.70 | diluent demand soft |
| WCS / CHV (heavy) | −$11.40 / −$11.60 | tighter than ~−$11.70 index |

Fort Saskatchewan Fractionation Build-Out
A wave of fractionation expansion is set to add 145 Mb/d of new capacity at Fort Saskatchewan by 2029 — lifting installed capacity from 391 to ~536 Mb/d.
CSV Midstream Solutions plans a 35 Mb/d plant (FID targeted early 2027, startup 2029), joining Pembina’s Redwater 4 (+55 Mb/d) and a Keyera Fort Saskatchewan II debottleneck (+8 Mb/d) online this month, with Keyera Fort Saskatchewan III (+47 Mb/d) targeting mid-2028. The buildout reflects growing confidence in Alberta NGL supply growth and the downstream capacity needed for rising condensate and liquids volumes.
| Project | Start-up | Mb/d |
|---|---|---|
| Pembina — Redwater 4 (RFS4) | Q2 2026 | 55 |
| Keyera — Fort Saskatchewan II debottleneck | Jun 2026 | 8 |
| Keyera — Fort Saskatchewan III | Mid-2028 | 47 |
| CSV — Fort Saskatchewan | 2029 | 35 |

AECO Steadies as NGTL Recovers
AECO ended the week at $1.7327 CAD/GJ (−$0.10 wk) in a tight $0.07 range as NGTL field receipts recovered and linepack finally moved above target.
NGTL field receipts gained ~1 BCF/d through the week and linepack is above target after weeks of shortfalls. The Westcoast Alberta-East outage ended, restoring ~0.2 BCF/d into Alberta at Gordondale; ~0.7 BCF/d of AB receipts remained off for turnarounds but are set to return this week. Storage withdrawals ceased and injections ran ~0.5 BCF/d, while West Gate volumes rose ~0.6 BCF/d. Western Canada sees heat building this week as Eastern Canada turns cooler.
NGTL maintenance: a cut to 62% FT-R capacity (no IT) on Segments 2, 5 and partial 9 runs Jun 16–20 — one of the largest on the system; operators may see higher-than-normal pressures.

Henry Hub Steady at $3.12 as Storage Builds
Henry Hub held in a ~10-cent range and settled near $3.12 USD/MMBtu as a +108 Bcf injection lifted working gas to 2,686 Bcf.
U.S. working gas rose 108 Bcf for the week ended June 5 to 2,686 Bcf — 151 Bcf (6.0%) above the five-year average but 5 Bcf below last year. Injections were led by the Midwest (+37), East (+34) and South Central (+28). Lower-48 production eased in June and LNG feedgas slipped on spring maintenance, while a developing El Niño — with some risk of “Super El Niño” strength — is a wildcard for cooling demand and global commodity volatility.
