Arthur Hayes, BitMEX co-founder, published an essay arguing that a prolonged U.S.–Iran conflict would likely push the Federal Reserve toward easier policy, which he believes would strengthen Bitcoin’s appeal as a scarce, decentralized asset. His macro thesis is that war-driven fiscal strain can translate into lower rates and renewed liquidity, and crypto tends to benefit when liquidity returns.

He pairs that view with a disciplined near-term posture, telling investors not to front-run the narrative. Hayes’ key guardrail is to wait for observable Fed action—actual rate cuts or clear evidence of money printing—before materially increasing exposure to Bitcoin and select altcoins. In his framing, geopolitics can set the stage, but policy execution is what validates the trade.

How Hayes ties geopolitics to Fed policy

Hayes anchors his argument in what he describes as a repeatable historical playbook, where major U.S. military engagements in the Middle East were followed by accommodative Fed decisions. He points to the 1990 Gulf War period, noting Fed cuts in November–December 1990 and a Fed Funds Rate decline from 7.00% in December 1990 to 3.00% by 1992, despite oil-linked inflation pressures.

He extends the pattern to the post-9/11 era, citing an emergency 50 bps cut under Greenspan and a broader easing cycle that aligned with the Afghanistan and Iraq campaigns. He also references the 2009 Afghanistan troop surge as a case where the policy rate was already at the effective lower bound and quantitative easing was already active, illustrating how military spending and an accommodative stance can coexist.

What to watch in the tape

Hayes frames the mechanism as fiscal pressure creating political cover and technical incentive for lower rates or balance-sheet expansion, which would debase fiat purchasing power and support Bitcoin as a store of value. In his playbook, Bitcoin’s upside is conditional on the timing and magnitude of easing, not on escalation headlines alone.

He contextualizes the setup with market levels and sentiment: at the time of writing, Bitcoin was around $66,200, roughly 30% lower year over year and about 47% below an October 2025 peak of $126,000, with sentiment described as extreme fear. His operational takeaway for traders and allocators is to monitor rate decisions and any balance-sheet expansion signals as the real “go” indicators, and treat geopolitics as a catalyst that still needs policy confirmation.
