NYMEX WTI (West Texas Intermediate, the US crude benchmark traded on the New York Mercantile Exchange) managed-money net long held at +82,872 contracts in the week to 23 June, released by the US Commodity Futures Trading Commission (CFTC) on 27 June, with 209,683 longs against 126,811 shorts 1. WTI net length has swung roughly 110,000 contracts over three weeks from the -26,694 net short of early June , a path that peaked in mid-June before easing back to +82,872. Brent speculative length stayed thin over the same week, holding near the compressed level managers reached when they flushed the book a fortnight earlier . Against WTI's length, that hollow Brent book leaves the widest speculative divergence of the window.
Brent absorbs the discount from the Iranian supply now reaching Asian buyers under General License X (GL X), OFAC's 22 June authorisation to lift Iranian crude through 21 August. EU Regulation 833/2014 bars European refiners from those barrels, so the two speculative books price two different supply worlds: one carrying the Iranian discount, one insulated from it.
A thin Brent long book carries a second-order risk for any trader pricing the global benchmark. With few longs left to absorb a move, a catalyst reversal such as a Doha breakdown or an OPEC+ surprise would be self-amplifying rather than cushioned.
