The Post-Quantum Banking Resilience Index in 2026: EO 14409, Global Deadlines, and Fiduciary Cryptographic Agility

Executive Order 14409, ANSSI's hard 2030 deadline and DORA Article 5 have moved post-quantum cryptography from a long-range technical goal to an active regulatory mandate. This index converts securing registries, high-frequency ledgers and SWIFT channels into a board-ready 0–5 scorecard that aligns ML-KEM, ML-DSA and SLH-DSA primitives with fiduciary liability and balance-sheet risk.

Quantum Dawn for CIB: From KyberLib to a Quantum-Resilient Payments Stack

BIS Quantum Dawn and the G7 January 2026 PQC roadmap have moved post-quantum cryptography from research to board agenda. This piece extends KyberLib from a toolkit into an enterprise CIB transition programme — covering high-value rails, trade finance, custody, and the disclosures regulators are now asking for.

Post-Quantum Payments Infrastructure: Why Banks May Replace Rather Than Retrofit Legacy Rails

Harvest-now-decrypt-later turns today's TLS-protected payment messages into tomorrow's decrypted exposure. ML-KEM and ML-DSA are an order of magnitude larger than the RSA and ECC keys legacy rails were sized for — retrofit triggers fragmentation, latency, and HSM exhaustion. The 2026 architectural decision is whether to patch or replace before the regulatory clock runs out.
