US-Iran fighting enters second night, rattling crypto markets and Republican unity

The US and Iran are trading blows for a second consecutive night, and the fallout is spreading well beyond the Persian Gulf. Bitcoin dropped below $62K, oil remains elevated, and a growing number of Republican lawmakers are publicly questioning whether President Trump’s Iran policy has veered off the rails.

What’s actually happening in the Gulf

US Central Command struck over 80 Iranian military targets on July 7-8, following the collapse of a ceasefire that had been negotiated just weeks earlier in June. President Trump publicly declared that ceasefire “over.”

Iran responded by targeting US military installations in Kuwait and Bahrain.

The conflict traces back to February 2026, when hostilities first escalated around the Strait of Hormuz. Iran had been conducting assaults on commercial shipping through the strait, a chokepoint that handles roughly a fifth of the world’s oil supply. The US initially responded with limited strikes, but the situation has steadily deteriorated.

Crypto catches the shrapnel

Bitcoin was trading in the range of $62,657 to $62,907 as of July 9, reflecting declines of approximately 1-5% depending on the timeframe.

Ethereum has experienced similar downward pressure. Oil prices surged above $100 per barrel earlier in 2026 as Strait of Hormuz disruptions threatened global supply chains.

The Republican problem

Some GOP members have begun publicly opposing Trump’s approach to Iran, raising pointed questions about war powers and the legal authority under which these strikes are being conducted.

There’s also the sanctions angle. Iran conflicts inevitably reignite debates about crypto’s role in sanctions evasion, which hands ammunition to lawmakers who want tighter controls on digital asset flows.

What crypto investors should be watching

Oil prices are the clearest leading indicator. If Strait of Hormuz disruptions continue pushing crude higher, expect continued pressure on risk assets across the board.

Market participants appear to be adopting a wait-and-see posture. The diplomatic mechanisms that would normally cool things down have already failed once.
