Key takeaway

The selling that compressed Brent-WTI is spent; the next clean move in the spread is wider.

CFTC Commitments of Traders for the week to 26 May show West Texas Intermediate managed money at net long +79,924, down from +98,219 on 19 May, a cut of 18,295 contracts.⁠1 The CFTC is the US derivatives regulator, and its weekly positioning data is the standard read on where speculative money sits. WTI is the US pipeline-leg benchmark on NYMEX; managed money still holds most of the length it built before the Iran memorandum. Brent Last Day managed money eased to +9,568 from +12,930, so money trimmed both legs rather than rotating out of WTI into Brent.

The book stays long both legs, with most of the length in WTI. Brent-WTI sits around $2 with WTI length still to carry out. The spread can compress on genuine diplomacy or widen if the June sanctions cliff or Hormuz risk reactivates. The re-widening to $3.55 on 29 May showed the path of least resistance.

The spread pays as convexity into the calendar, not as a directional bet on the flat price. From here the spread carries cheap optionality on the three June dates rather than a view on where Brent settles.

Deep Analysis

In plain English

Brent and WTI are the world's two main oil price benchmarks, traded on different exchanges and reflecting different supply routes. Brent is the European and global one, based on oil loaded from ships in the North Sea. WTI (West Texas Intermediate) is the American one, based on oil stored at Cushing, Oklahoma, delivered by pipeline. Investors and trading funds usually bet on both. Last week, funds that had been betting heavily that WTI would rise cut those bets by about 18% after the Iran diplomacy news arrived, and trimmed their smaller Brent bets too. The gap between Brent and WTI prices is now around $2 a barrel, and funds still hold a large WTI bet that could come out if prices keep falling.

Deep Analysis
Root Causes

The 18,295-contract cut in WTI managed-money length in the week to 26 May followed a 78,977-contract fall in WTI open interest the week before. The Iran MOU arrived four sessions after the WTI long was established, meaning funds were already long on a thesis (tightening supply + GL 134C legitimacy) that the MOU invalidated within a trading week.

Managed money did not rotate into Brent: its Brent Last Day net long eased to +9,568 from +12,930. The MOU left the highly enriched uranium stockpile untouched and set a 30-60 day timeline, so the physical supply risk did not resolve , it just deflated enough to invalidate the WTI overland-supply squeeze narrative.

The residual ~$2 Brent-WTI spread carries WTI length that can still come out, so the spread can move on WTI liquidation as well as on Brent risk.

What could happen next?
  • Risk

    With WTI managed money at net short -1,269, any Hormuz reactivation or GL 134C cliff event on 17 June faces no mechanical spread compressor, allowing Brent-WTI to widen toward the pre-MOU $4-5 band within one trading session.

    Immediate · Suggested
  • Consequence

    The Brent net long of +52,000 is exposed to rapid unwind if the Iran MOU reaches a signed deal that credibly re-opens Hormuz, potentially swinging Brent-WTI back to $1 or below.

    Short term · Suggested
  • Meaning

    The 173,849-contract speed of the WTI unwind confirms that the prior long was momentum-driven rather than fundamental: funds entered on the supply-tightness thesis and exited on the first diplomatic signal, with no remaining conviction position in either direction.

The OBR's 28 October forecast assumed $82 oil for 2026 and 2027, from market prices for the ten working days to 19 August, and blamed dearer wholesale energy on the war without naming Iran. It expects CPI inflation close to 4% in early 2027 even at that price.

Hengaw reported the 3 November hangings of Amirhossein Maleki and Amirhossein Ebrahimi in Isfahan, saying Ebrahimi was tortured into confessing and that nine of 12 people sentenced to death in the case have now been hanged. Iran's judiciary holds that the defendants killed members of the security forces.

FINTRAC worked with the US Treasury on the 6 November designation of eight money services businesses in British Columbia, Ontario and Quebec. Treasury says the businesses still operate, some under new names, so closing them falls to Ottawa.

Kuwait condemned the Houthi missile fired towards the Madinah region on 5 November and restated its support for Saudi Arabia, the Qatar News Agency reported. Its state tanker company, Kuwait Oil Tankers Company, is among the Gulf state fleets on Iran's expanded Hormuz list.

Treasury designated an alleged Chandigarh false-flag network on 4 November and eight Canadian exchangers on 6 November, while State sanctioned alleged MANPADS intermediaries. None of the actions touches an oil buyer; they target the paper, cash and procurement around Iran's trade.
