Will the US officially declare war on Venezuela by 2025?

Market context

A formal declaration of war by the United States Congress against Venezuela remains an extraordinarily remote prospect. The US has not issued a formal declaration of war since 1942, and the constitutional threshold—requiring passage through both chambers and presidential signature—represents a far higher bar than military intervention, sanctions, or authorisation for use of military force. Current US-Venezuela relations involve diplomatic tensions, sanctions regimes, and rhetorical hostility, but no active military engagement or imminent trigger for congressional war powers activation.

Historical precedent suggests the 1% probability reflects appropriate scepticism. The last formal declaration came against Bulgaria during the Second World War; since then, American military actions—Korea, Vietnam, Iraq, Afghanistan—proceeded under executive authority or congressional authorisations short of formal war declarations. Venezuela's strategic position, lack of direct military threat to US territory, and the domestic political cost of a formal declaration make congressional passage extraordinarily unlikely absent a dramatic escalation such as a direct armed attack on American soil or forces. Even hawkish policymakers have historically preferred AUMF mechanisms that preserve executive flexibility.

Traders should monitor statements from the Trump administration following its January 2025 transition, as rhetoric around Venezuela has periodically intensified. Congressional composition and any significant military incidents involving US personnel or allies would represent the primary catalysts for shifting probabilities. The settlement window's December 2025 timing means any movement would require rapid congressional action within a compressed timeframe, further constraining realistic scenarios for formal war declaration.
