This article argues that financial infrastructure is already vulnerable to quantum attacks due to the convergence of advanced AI-driven error correction and accelerated hardware progress. It emphasizes the urgent need for post-quantum cryptography in long-lived settlement systems, noting that "harvest-now, decrypt-later" threats are active regardless of current fault-tolerant timelines.
Guest Post: Why Financial Infrastructure Needs Post-Quantum Security

Guest Post By Ryan Kirkley, Founder & CEO, Global Settlement Holdings. A temporal asymmetry lies at the heart of financial infrastructure. Settlement systems and payment rails are built to run for thirty to fifty years, and most of what moves the dollar today was last built forty years ago. Fedwire settled an average of $4.6 trillion a day in 2025, CHIPS another $2 trillion, and a stablecoin market that did not exist fifteen years ago now holds more than $300 billion of dollar liabilities on public blockchains. All of it authenticates itself with two families of mathematics, RSA and elliptic-curve cryptography, and quantum computers able to run Shor’s algorithm against production key sizes now sit within a decade. Any infrastructure deployed today on classical-only cryptography is born obsolete. Harvest-now, decrypt-later campaigns, in which adversaries record encrypted traffic today to decrypt once the hardware arrives, are…
