According to market sources, the U.S. Department of Justice (DOJ) is investigating a series of suspicious crude oil transactions that occurred before the release of announcements related to U.S. President Donald Trump, involving approximately $2.6 billion. These transactions reportedly attracted regulatory attention due to their unusually precise timing, and the investigation focuses on whether insider trading or preemptive market manipulation based on policy information was involved. The DOJ has not yet released further details.
