Is Finance sector PQC Quantum Proof? Cyber Program & PQC

Risk: high · Confidence: high · Reviewed: 2026-07-19

Verdict

Financial institutions should treat PQC as multi-year operational risk: inventory, third parties, market infrastructure dependencies, and board reporting. Not quantum-proof until classical public-key dependencies are migrated or accepted with residual risk.

Overview

Banks and fintechs already run strong control frameworks; add crypto inventory and HNDL for customer and market data.

Program inventory focus: High-value transactions and long-lived customer confidentiality. Typical classical surfaces: Payments, market data TLS, customer auth. Cross-read /security/program and /assessment. Educational only—not compliance advice.
