The Iran war premium is back, and crypto is paying for it.

Bitcoin slid 2.1% over the past 24 hours to $75,633 in Asian hours Thursday, down 3% on the week, as Brent crude jumped 7.1% to $126.41 a barrel - the highest intraday level in four years - on a report that President Donald Trump is set to receive a briefing on new military options against Iran. The report added U.S. Central Command has asked for hypersonic missiles to be deployed to the Middle East. The Strait of Hormuz has been effectively shut since the war began in late February, choking flows of crude, natural gas, and oil products. Brent has been carrying a heavy war premium all year, with prices up over 100% year-to-date.

Ether dropped 3.4% to $2,244 and is down 4.4% on the week. XRP fell 2.1% to $1.37. Solana lost 2.6% to $82.62. BNB shed 1.9% to $615. The only green print in the top 10 outside stablecoins is dogecoin, up 3.8% on the day.

Risk assets are giving back gains across the board. Nasdaq 100 futures erased an earlier 1.1% rally, MSCI's Asia Pacific share index fell 1.4%, and European equities were primed to drop 1% at the open.

Bitcoin's resilience through the early stages of the war is being tested. The asset has held a tight band between $74,000 and $78,000 through April even as oil ran from $98 to $126. BTC is now $50,000 below its October 2025 all-time high of $126,000.

Fernando Lillo, director at exchange Zoomex, said any break above $80,000 requires the war premium to unwind. He flagged a possible scenario where the Trump administration lifts the blockade in coming days, framing it as a response to positive steps by Iran, to engineer a relief rally. A potential lifting of restrictions and lower oil prices could trigger an accelerated influx of capital into risk assets, paving the way for Bitcoin to consolidate above $80,000 and move toward $85,000.
