Is SWIFT messaging Quantum Proof? Industry Quantum Risk
Verdict
Wholesale messaging networks are not quantum-proof by brand. Institutions must inventory customer-side crypto, HSMs, and provider roadmaps—verify current network guidance from primary sources.
Overview
Correspondent banking depends on authenticated messaging. Quantum risk includes both network-provided security and bank-owned endpoints.
Treat provider PQC timelines as vendor-risk inputs, not automatic coverage.
