CFTC adviser ordered staff to retract oil-trade referral

What happened
Bloomberg reported that Mel Gunewardena, a senior adviser to Commodity Futures Trading Commission Chair Michael Selig, told a Market Oversight supervisor to retract a referral to the Division of Enforcement on unusually timed oil and equity futures trades. Career analysts had flagged the trades for possible insider trading after identifying participants, people familiar with the matter told Bloomberg. The CFTC declined to comment, saying it cannot confirm or deny investigations. Gunewardena did not respond through the agency press office, Bloomberg said.
Why it matters
The episode tests whether the CFTC's forensic staff can move a potential insider-trading case when a political appointee's adviser steps in. Enforcement actions at the agency have fallen sharply (13 in fiscal 2025 and a similar pace in 2026, versus 58 in 2024 and 96 in 2023, Bloomberg cited agency data). Large, well-timed bets around Iran-war headlines have also drawn Senate pressure for a public accounting.
What’s next
Watch for any public CFTC or DOJ update on the March 23 oil trades, House or Senate Agriculture/Banking follow-up with Selig, and whether Enforcement files charges or closes the matter without action.
More context
March 23 timeline: In a two-minute window starting about 6:49 a.m. ET, traders sold contracts equal to at least 6 million barrels of Brent and West Texas Intermediate crude — more than 8.5 times the volume that had changed hands at that hour over the prior week, according to Bloomberg's account of market data. S&P 500 futures worth more than $2 billion in notional value also traded in the same burst. About 15 minutes later, President Trump posted on Truth Social that he was reversing threats to strike Iranian energy infrastructure unless Iran reopened the Strait of Hormuz. Brent then fell as much as 14%; U.S. crude dropped in the double digits; U.S. and European equities jumped about 4% from session lows to intraday highs.
Agency response: An unnamed CFTC official told Bloomberg that the original findings were U.S.-focused and that leadership decided the agency needed a broader international review of futures, swaps, over-the-counter activity, options and ETFs. The official said Gunewardena, a former Goldman Sachs and State Street executive who rejoined the agency weeks earlier as head of International Affairs and senior markets adviser, was best placed to lead that review. The official also said the Division of Enforcement is still examining March and April trading, with a particular focus on March 23.
Strongest argument each side: Critics say ordering Market Oversight to retract a referral broke the usual path from forensic data to enforcement lawyers. Former CFTC Enforcement Director Aitan Goelman told Bloomberg that in every previous administration he knew, such an intervention "would not just have been unusual — but never done." Defenders of the agency's handling say a U.S.-only referral was too narrow for trades tied to a global oil shock and that a senior markets adviser should run a wider data pull. Sen. Elizabeth Warren (D-Mass.) called the reported intervention "disturbing" and said Selig and Gunewardena should answer Congress on the status of probes.
What remains unknown: The traders flagged by Market Oversight have not been named publicly. Public data alone cannot show whether the March 23 burst was luck or advance knowledge — Tim Skirrow of Energy Aspects told Bloomberg it was one or the other. A person familiar with the matter told Bloomberg earlier this year that the Justice Department opened a parallel probe; a department spokesperson last week declined to comment on its status. By July, the supervisor told to retract the referral had left the agency; other team members resigned or were reassigned. Bloomberg reported it is not clear whether those moves were related.
