WTI — Flat on the Week, Coiled on Hormuz

WTI ended the week slightly higher, opening Monday at $88.50 and climbing to a weekly high of $97.00 USD/bbl on Wednesday before surrendering most of those gains into Friday's close.

Markets have remained in limbo awaiting a resolution in the Strait of Hormuz. The mid-week spike was tied to fresh Iranian missile launches at several Gulf targets and reciprocal American strikes on Iran's Qeshm Island, before reports of a potential Israel–Lebanon agreement softened prices into the back half of the week. Notably, WTI's moves this week coincided with broader weakness across equity markets, breaking what had been a near-perfect mirrored relationship over the prior month.

Official Hormuz transits remain at roughly 10% of pre-war volumes, and additional analysis suggests an estimated 65% of outbound tankers are running dark. Vortexa estimates Gulf oil-on-water stocks have fallen from 184 million barrels in late March to ~148 million barrels, implying outflows not captured in typical counts. Empty tankers are not returning to the Gulf in volume, preventing producers from restarting shut-in capacity.

China's Import Collapse Anchors the Global Balance

Arguably the most important story for global crude balances is China's import collapse, with May imports falling to a decade-low 6.7 million bpd as Chinese refining margins remain deeply negative — roughly half of pre-war levels, yet domestic mobility indicators show no commensurate demand destruction. The likeliest explanation is a large-scale draw on Chinese strategic reserves buffering domestic consumption. The decline has freed up seaborne barrels for other Asian buyers, with South Korea, Japan, and Taiwan returning imports to March levels absent Chinese competition. Iranian Light for Chinese delivery has slipped below Brent for the first time since April, adding pressure on Iran when exports are already constrained.

U.S. Inventories Draw for an Eighth Straight Week

The EIA confirmed a weekly crude draw of 8.0 million barrels — the eighth consecutive decline — with commercial stockpiles now firmly below the five-year seasonal average. The SPR drew an additional 8.0 million barrels. While refined-product stocks rose week-over-week, a total product draw of ~11.2 million barrels continues a trend in place since the start of the conflict. Record crude exports remain the primary driver, with a draw of 5.6 million bpd this past week as global refiners hunt for non-Hormuz supply. With inventories declining rapidly, reputable sources have begun to sound the alarm: ExxonMobil's Neil Chapman warned dated Brent could reach $150–160 USD/bbl if inventories approach critically low levels, while JPMorgan and Rosenberg Research both pegged the tipping point at end of June absent Hormuz normalization.

Trader
Takeaway

The crude tape is range-bound but asymmetrically tilted to the upside: Hormuz transits stuck near 10%, eight straight U.S. draws, Cushing nearing its operational floor, and China leaning on reserves rather than buying. A flat week masks a balance one headline away from a squeeze — credible voices now flag end-June as the tipping point absent a deal.

Crude Storylines

GEOPOLITICAL

Dark Tankers Mask Hormuz Activity

With official Hormuz transits at ~10% of pre-war volumes, an estimated 65% of outbound tankers are running dark. Empty tankers are steering clear of the Gulf as Tehran's reported tolling-system ambitions reshape the world's most critical chokepoint.

IRAN

Iranian Crude Slips to Discount

Iranian Light slipped to a $0.50–$1.00/bbl discount to Brent for June Chinese delivery — the first since April — as Iranian exports hit a six-year low of 260,000 bpd vs. a 2025 average of 1.67 million bpd. Margin compression is forcing teapots to cut run rates.

SUPPLY

Mixed Upstream Recovery Timeline

Kuwait sees output back to 70% of pre-war within 6–8 weeks of a Hormuz reopening and refining capacity in 2–3 weeks. But ADNOC warns full transit recovery could take until mid-2027, and the IEA estimates a best case of 6–8 months from any deal struck today.

INFRASTRUCTURE

UAE Plans First Multi-Fuel Pipeline

The UAE will build its first multi-fuel pipeline to keep gasoline, diesel and jet exports flowing around Hormuz, with a broader east–west line under early discussion. All planned infrastructure sits within range of Iranian missiles, though rerouted Fujairah flows have held up despite repeated drone strikes.

DEMAND

China Tapping Deeper into Stockpiles

May seaborne crude imports are estimated at a decade-low 6.5 million bpd, down from 8.1 million in April, as refiners cut runs. Commercial stocks are drawing ~1 million bpd, but the 200M+ barrel buffer built since early 2025 can sustain drawdown through mid-September.

U.S. SUPPLY

Cushing Nears Operational Minimum

Record 5.6 million bpd U.S. exports drained Cushing to 22.4 million barrels by May 29, with satellite data confirming a further 500k draw through June 2. Phillips 66 sees the ~20 million barrel operational minimum — untouched since 2015 — within reach in coming weeks.

OPEC+ / SPR

SPR Loans Yield 40M-Barrel Windfall

DOE structured ~133 million barrels of SPR releases as loans repayable with premiums of up to 24%, leaving the reserve ~40 million barrels larger than its pre-release baseline once the conflict ends. The SPR stands at 357.1 million barrels, down from ~415 million at the start of March.

Differentials — A Force-Majeure Shock to the Condensate Complex

A significant disruption hit the week of June 2: a force-majeure declaration from Cenovus tied to electrical and power issues at its Christina Lake and Foster Creek operations after a lightning storm.

Cenovus issued the FM letter Monday, indicating it may need to cut condensate purchases and heavy deliveries. Long condensate, Cenovus was forced to sell excess into an already-oversupplied June market. The effects carried into July, where condensates traded wide and heavies sat around −$12.00 USD/bbl.

June: The Condensate Sell-Off

The most notable move was the sell-off in June condensates. June C5-PCE NAM closed May near −$4.75/bbl, opened Monday around −$10.00/bbl and softened steadily, trading as low as −$11.00/bbl Thursday before a modest Friday recovery to −$10.25/bbl. C5-FSPL followed, opening near −$9.80/bbl and widening to −$10.90/bbl mid-week before settling ~−$10.20/bbl. C5-CRW saw light activity, trading −$10.30/bbl Friday. Sweets reflected the same pressure but less severely — PCE ranged −$3.10 to −$3.90/bbl, PEM weakened to −$4.50/bbl Thursday before closing ~−$4.00/bbl. Medium sours were light (LSB −$5.75, PSO ~−$6.30). Heavies actually traded inside index: WCS opened ~−$16.00/bbl Monday and improved to −$14.50/bbl by Wednesday.

July: Naphtha Weakness Spills North, Heavies Firm

July's trade cycle began Monday with condensates extremely weak on the back of a collapsed European naphtha market and the redirection of U.S. Gulf Coast naphtha north into Canada — the arb to ship to Europe has closed, so sellers are better off moving condensate north. July C5-PCE NAM opened ~−$6.30/bbl, reached −$9.50/bbl Thursday, then recovered to ~−$7.70/bbl Friday; C5-FSPL tracked near-identically. Sweets bounced between −$2.00 and −$1.30/bbl. Among medium sours, MID opened sharply at −$6.90/bbl and tightened to −$3.80/bbl Friday while LSB improved to −$3.90/bbl — the two traded just $0.15/bbl apart versus a typical ~$1.00 gap, with MID supported by strong WCS relative to SW. Heavies outperformed June: WCS oscillated −$11.90 to −$13.00/bbl and settled near −$12.00/bbl Friday.

Trader
Takeaway

The Cenovus FM is a condensate story, not a heavy story — June C5 dislocated ~$5–6/bbl while WCS firmed inside index. With European naphtha collapsed and the trans-Atlantic arb shut, condensate length is being forced north; expect continued C5 weakness into July. The LSB/MID compression to $0.15/bbl flags refiners favouring medium sours on WCS strength — a relative-value setup worth watching.

AECO — Range-Bound, Supported by Another Storage Draw

The AECO daily index traded within a ~$0.20 CAD/GJ range last week, barely topping $2 on Thursday before settling at ~$1.83/GJ Friday.

NGTL field receipts began to recover early in the week, gaining back ~1.4 Bcf/d, but plummeted again on June 1 to ~12.2 Bcf/d. The Westcoast pipeline ran an outage on the Alberta East leg that drove zero flow into Alberta at Gordondale (previously ~0.25 Bcf/d), with the outage expected to end tomorrow. Roughly 0.8 Bcf/d of AB field receipts remain offline for planned turnarounds on NGTL's system. NGTL linepack swung back and forth and ran ~1 Bcf/d short of target Thursday, prompting NGTL to change the line tolerance and spiking daily prices to settle at $2.01 CAD/GJ. Willow Valley deliveries were consistent near ~200 mmcf/d early, jumping to ~600 mmcf/d for one day Thursday; West Gate stayed volatile between 1.6 and 2.3 Bcf/d. Small storage withdrawals continued sporadically as reduced receipts and incremental deliveries balanced the system.

Local temperatures are expected to return to average this week after heavy rain and cooler weather reduced an elevated wildfire risk across central and southern Alberta. On the longer-term demand side, LNG Canada advanced its Phase 2 expansion with Fluor receiving a limited notice to proceed — underscoring continued growth in North American LNG export capacity.

Henry Hub — Steady Near $3.22 on Summer Heat

Henry Hub was quiet, trading within a 17-cent USD/MMBtu range and settling at ~$3.22 after a week of hot weather across most of the U.S.

The EIA reported a 95 Bcf storage injection, lifting inventories to 2,578 Bcf — 138 Bcf above the five-year average but 3 Bcf below last year. U.S. LNG exports declined to 10.2 million tonnes in May on planned maintenance at major facilities including Freeport, Cameron, and Sabine Pass, reducing feedgas demand. Warmer weather is expected to continue across most Central and Eastern U.S. states this week. Despite lower overall LNG exports, shipments to Asia rose to a one-year high as stronger Asian prices pulled cargoes away from Europe; Europe remained the largest destination, though its share slipped from April.

Henry Hub Storylines

U.S. LNG

LNG Maintenance Reduces Exports

U.S. LNG exports fell to 10.2 MT in May as seasonal maintenance cut output at Freeport, Cameron, Sabine Pass and Golden Pass. Asia-bound shipments still rose to a one-year high on premium Asian pricing, while Europe took the largest share.

CHINA

China LNG Imports Rebound

China's LNG imports recovered in May as buyers stocked ahead of summer demand. Reduced Qatari deliveries were offset by Canada, Malaysia, Oman and Russia — and stronger Chinese demand could tighten competition with Europe for cargoes.

STORAGE

Storage Build Leaves Stocks Stable

U.S. working gas rose 95 Bcf for the week ended May 29 to 2,578 Bcf — slightly below last year but above the five-year average and within the historical range.
