trading sanctions

Venezuela has been under U.S. oil trading sanctions since 2019, but in November the U.S.

The United States imposed oil trading sanctions on Venezuela in 2019 after calling Maduro's re-election the previous year a sham.

Since the United States first imposed oil trading sanctions on Venezuela, many firms removed equipment and staff and wrote off hundreds of millions dollars of their assets there.

Russia is one of the world's major oil exporters and it is being targeted by economic and trading sanctions.

While it remains uncertain who, if anyone, specifically had advance knowledge of the attack or "whether they may have made any securities or commodities trades based on that information," Warren urged the SEC to look into whether any of the trades violated the Insider Trading Sanctions Act of 1984, which prohibits individuals from purchasing or selling a security while in possession of material, nonpublic information.
