Quantum Finance: Securing the Future of LCs & SBLCs 1 Quantum computing threatens to break classical encryption, putting LC messages, guarantee confirmations, and cross-border settlements at risk. 2 Trade finance must migrate to post-quantum cryptography (PQC) to ensure resilience beyond 2030. 3 Quantum-safe algorithms—lattice-based, hash-based, and multivariate cryptography—will safeguard SWIFT messages, digital signatures, and guarantee instructions. 4 LC and SBLC authentication layers will sh
