The White House has restricted employee trading after a set of unusual oil-market transactions raised concerns about potential use of non-public information.

Scope of the advisory

The administration warned staff not to use official information for trading in futures and related positions while inquiries proceed, citing market integrity concerns.

Details of the suspicious trade

Authorities flagged a case where an unidentified trader opened positions totaling $500 mln within a minute before a public decision regarding Iran.

Shortly after that decision, global oil prices fell by 15%, which prompted immediate reviews of transaction timing and market impact.

Investigation and status

Investigators have not publicly identified the participant involved in the trading sequence and continue to gather records and communications for review.

The White House restriction is presented as a precautionary step to prevent the misuse of privileged information while the inquiry remains active.

Market implications

Officials emphasize that the measure aims to preserve confidence in government-market boundaries and to support ongoing probes by relevant authorities.

Further statements and procedural details are expected as investigators analyze transaction data and determine whether regulatory or legal actions are warranted.
