The US Senate voted down a second war powers resolution on Iran this week, rejecting a measure that would have restricted the president's ability to launch military action without congressional approval. The decision comes as Bitcoin posted a notable price dip and as the Treasury Department continues to tighten sanctions on crypto-related entities tied to sanctioned nations.
Senate votes down war powers resolution
The resolution, the second such attempt this year, failed to secure the necessary votes in the Senate. Proponents argued it was needed to reassert congressional authority over war-making, while opponents said it would tie the president's hands during ongoing tensions with Iran. The first resolution was rejected earlier in 2026.
Bitcoin slides amid geopolitical jitters
Bitcoin's price dropped sharply in the hours following the vote, though the exact trigger remains unclear. Traders pointed to a combination of the Senate news and broader risk-off sentiment. The dip erased gains from earlier in the week and pushed the asset below a key psychological level.
Crypto sanctions regime expands
Separately, the US Treasury Department has been quietly broadening its sanctions framework targeting digital assets. New designations this month hit several crypto addresses and platforms allegedly used to move funds for Iran's Islamic Revolutionary Guard Corps. The moves signal that Washington is treating crypto as a central piece of its financial pressure campaign, even as Congress debates the limits of executive war powers.
The rejection of the war powers resolution doesn't change the sanctions trajectory. The Treasury is expected to issue additional guidance on crypto compliance for financial institutions in the coming weeks.
