Bitcoin BTC$73,288.76 fell below $73,000 to the lowest level since April 13 on Thursday as renewed fighting between the U.S. and Iran rattled global markets, pushing oil higher and dimming hopes for a permanent ceasefire.

The selloff followed U.S. strikes in southern Iran. Iran's Revolutionary Guards said they retaliated by targeting the American base used to launch the attacks, warning future responses would be "more decisive," the New York Times reported. Kuwait, which hosts five U.S. bases, said it intercepted hostile drones and missiles.

The escalation dimmed expectations that Washington and Tehran are close to an agreement that could stabilize the Strait of Hormuz, a key global oil shipping route.

Odds of a permanent ceasefire being reached by the end of the month are now just 8% on Polymarket, down from a 70% peak over the weekend. Perceived odds of it being reached by the end of next month slid to 42% from 76%.

On Kalshi, traders are betting traffic in the strait will remain subdued. Brent crude jumped nearly 4% to around $96 per barrel, fueling concerns that higher energy prices could add to inflation pressures worldwide.

Crypto markets reacted alongside broader risk assets. According to Mercado Bitcoin’s head of research, Rony Szuster, investors remain focused on geopolitical risks and upcoming U.S. inflation data, particularly Thursday’s PCE report, the Federal Reserve’s preferred inflation gauge.

“The crypto market remains structurally resilient, supported by long-term accumulation and the strength of AI and blockchain infrastructure narratives,” Szuster said in a note shared with CoinDesk.

“In the short term, the market remains more sensitive to geopolitical developments and the return of institutional flows after the U.S. holiday, keeping bitcoin in consolidation while altcoins trade in a more selective environment,” he added. Stay alert!
