US senators are demanding the SEC and FINRA investigate trading linked to Venezuela's military action that ousted President Maduro. The probe targets potential market manipulation or insider trading around the US-backed operation that removed the authoritarian leader. This follows reports of unusual bond market activity during the February 2019 coup attempt.

The senators' letter underscores concerns about regulatory oversight gaps in volatile geopolitical events. Market impact remains unclear, but the investigation could force greater transparency in cross-border bond trading. Investors are watching for potential regulatory crackdowns on speculative positions tied to regime changes.
