A large crude oil block trade surfaced before Iran said the Strait of Hormuz was fully open, adding to scrutiny over whether traders acted on market-moving information ahead of official comments.
The numerical and timing details in the claim are consistently echoed across multiple fetched secondary reports: 'Investors Bet $760 Million on Oil Short Before Strait Reopening | KuCoin', 'Another case of insider trading? A mysterious trader placed a $760 million short position just 20 minutes before the Hormuz opening, precisely targeting crude oil.', and 'CFTC Launches Probe into Suspected Insider Trading Ahead of Iran's Strait of Hormuz Opening Announcement' all state that 7,990 Brent crude futures were sold shortly before Iran's Strait of Hormuz reopening announcement and that oil prices fell by as much as 11% intraday. The KuCoin and Moomoo pages explicitly attribute the information to Reuters and LSEG. However, confidence is reduced because the primary linked X posts and BlockBeats page could not be fetched directly, and the KuCoin page contains an internal inconsistency where one paragraph says '$7.6 billion' while the headline and the other corroborating pages say '$760 million'. That inconsistency appears more likely to be an error in the republished text than evidence against the broader claim.
A large crude oil trade worth about $800 million appeared at 8:24 a.m. ET before Iran announced that the Strait of Hormuz was fully open. The new report says WTI crude briefly fell below $80 per barrel by 9:10 a.m. after comments from Iran and Trump. This adds to earlier reporting that 7,990 Brent crude futures contracts worth about $760 million were sold shortly before the reopening announcement, intensifying scrutiny over pre-announcement energy market trading.
