Coinbase CEO Says Bitcoin Paradoxically Boosts U.S. Dollar’s Reserve Role
On Dec. 28, 2025 Coinbase CEO Brian Armstrong said Bitcoin is oddly reinforcing the U.S. dollar’s role as the world’s reserve currency by serving as a market-based check on runaway inflation and excessive government deficits. Armstrong framed BTC not as a direct rival to fiat but as a discipline that influences policy and investor behavior, tightening the consequences of devaluation and large-scale fiscal stimulus.
The comment matters because it reframes part of the crypto debate: rather than displacing reserve fiat, Bitcoin might indirectly stabilize it by raising political and market costs for inflationary policy. For investors and policymakers, the assertion highlights evolving narratives around digital assets — from speculative stores of value to macroeconomic signals that could shape regulation, central-bank strategy, and institutional adoption moving into 2026.
