Former SEC chair Jay Clayton says regulators would scrutinize trading ahead of Trump post

• Volume surged around 6:50 a.m. ET on Monday, roughly 15 minutes before Trump's social media post that lifted equity markets and pushed oil prices lower
• Regulators will 'go back and track every single thing, everyone' to reconstruct the activity and identify participants, though surveillance is easier in cash equities than in futures and commodities markets
• Clayton stated 'the law is not as clear as it should be' regarding such trading and suggested Congress should act to clarify regulations across all markets

Summary

Key Development:

Trading volume in S&P 500 and oil futures surged unusually on Monday around 6:50 a.m. ET, approximately 15 minutes before President Donald Trump posted on social media that the U.S. and Iran had held talks and planned strikes on Iranian infrastructure would be halted. Trump's announcement subsequently lifted equity markets and pushed oil prices lower.

Regulatory Response:

Former SEC Chair Jay Clayton, now U.S. Attorney for the Southern District of New York, confirmed Wednesday on CNBC that regulators would scrutinize the suspicious trading activity. "Any move like that in advance of any announcement, the regulators are going to look at," Clayton stated. Authorities plan to reconstruct the trading activity and identify all market participants involved across various markets.

Surveillance Challenges:

Clayton highlighted that regulatory oversight varies by market type. Cash equities markets offer the most comprehensive surveillance capabilities, allowing detailed tracking of participants and timing. However, futures and commodities markets present greater monitoring difficulties and less transparency.

Legislative Concerns:

Clayton emphasized that current laws regarding such trading activities lack clarity. "The law is not as clear as it should be," he said, calling for Congressional action to establish clearer standards across all markets. He noted disagreement exists about whether such trading is permissible, adding, "There are a lot of people who say this is okay. I don't feel like it's okay."

Market Implications:

The incident raises concerns about potential information leaks ahead of market-moving presidential announcements and highlights vulnerabilities in market surveillance systems, particularly in derivatives markets. The SEC declined to comment on any ongoing investigation.
