A surge in trading activity suggests possible insider knowledge ahead of Iran’s decision to allow shipping through the Strait of Hormuz, prompting the US CFTC to investigate potential market abuse amid fears of sensitive information leaks.
A fresh row over market fairness has emerged in the crude market after a Reuters report said traders placed about $760 million in bets on falling oil prices just before Iran announced it would allow commercial shipping through the Strait of Hormuz.
According to Reuters, 7,990 Brent crude futures contracts were sold in a one-minute burst beginning at 12:24 GMT on 17 June, shortly before Iranian foreign minister Abbas Araghchi said on social media that all commercial vessels could pass through the waterway during the ceasefire. Oil prices then dropped sharply, with Brent falling as much as 11% intraday.
The timing has intensified questions over whether some investors may have had advance knowledge of a policy move with obvious market consequences. Reuters also reported that the episode followed two other sizeable and well-timed crude bets: a $950 million short position ahead of a two-week ceasefire announcement between the US and Iran on 7 June, and sales worth about $500 million placed minutes before Donald Trump said he would delay strikes on Iran’s energy infrastructure on 23 May.
The US Commodity Futures Trading Commission has now opened an inquiry into possible unfair trading, according to Reuters, and is seeking data from the Chicago Mercantile Exchange and Intercontinental Exchange as part of its review. The regulator is examining trading just before major policy announcements and looking for signs that information may have leaked to select investors.
The Strait of Hormuz remains one of the world’s most sensitive energy chokepoints, carrying a large share of global crude shipments. Any suggestion that traders are profiting from privileged access to geopolitical decisions risks rattling confidence in a market already prone to violent swings when tensions in the Middle East escalate.
For now, the key question is whether the trades reflected sharp but legitimate speculation, or something more serious. If investigators find evidence of advance disclosure, the episode could deepen scrutiny of how geopolitical information moves through the oil market and who gets to act on it first.
