Bitcoin and ether slid after the Fed held rates but struck a hawkish tone under new Chair Kevin Warsh, signaling greater concern about inflation than growth. The divergence — risk equities lifted by a Trump-Iran deal while crypto sold off — highlights crypto's growing sensitivity to real-rate signals over broad risk appetite.
If the Iran deal signals a broader de-escalation in geopolitical risk and oil prices fall, inflation expectations could drop quickly, undermining the hawkish Fed narrative and giving crypto a sharp relief rally.
Warsh has a well-documented hawkish track record and his first meeting tone suggests the Fed's reaction function has shifted toward prioritizing inflation credibility, which historically prolongs the period of restrictive real rates that weigh on BTC and ETH most heavily.
