  • Post-quantum cryptography — 76 articles

    NIST PQ standards, harvest-now-decrypt-later threat, hybrid handshakes, and the migration of banking cryptography to lattice-based primitives.

  • Quantum computing — 25 articles

    Hardware progress, quantum algorithms, the timeline-to-threat, and where quantum compute crosses paths with banking workloads.

  • Cloud-native banking — 23 articles

    Kubernetes, service mesh, multi-region resilience, and the cloud-native architecture patterns banks are adopting under DORA.

  • Platform engineering — 15 articles

    Internal developer platforms, golden paths, paved roads — how banking technology orgs ship engineering productivity.

  • Sovereign cloud — 13 articles

    Data-residency, regulatory-region cloud, and the architectural trade-offs of running banking workloads inside sovereign boundaries.

  • Blockchain — 10 articles

    Distributed ledger technology in financial infrastructure — consensus, validators, smart-contract execution, and where the primitive shows up in banking.

  • Crypto-agility — 10 articles

    Inventorying cryptographic assets, defining a migration path, and shipping replaceable crypto boundaries in production code.

  • Cryptography — 9 articles

    Applied cryptography in banking — hashes, signatures, KEMs, key management, and the cryptographic primitives that secure the rails.

  • Operational resilience — 9 articles

    Important business services, impact tolerances, severe-but- plausible scenarios, and the operational-resilience programme banks must run.

  • ML-KEM — 8 articles

    FIPS 203 — the standardised post-quantum key encapsulation mechanism (formerly CRYSTALS-Kyber).

  • Cybersecurity — 8 articles

    Operational security in banking — threats, controls, incident response, and the regulatory expectations around resilience.

  • Harvest now, decrypt later — 6 articles

    The HNDL threat model — adversaries capturing encrypted traffic today to decrypt once quantum hardware is available.

  • ML-DSA — 5 articles

    FIPS 204 — the standardised post-quantum digital signature algorithm (formerly CRYSTALS-Dilithium).

Reading the Emerging-Technology Risk Horizon for Banks in 2026

Regulators have started scanning the horizon out loud. Reading the 2026 emerging-technology landscape for banks across three converging vectors — personalised AI intelligence, synthetic financial crime, and programmable finance — and a framework for turning weak signals into supervisory action before harm scales.

The Agentic AI Index for Banks in 2026: Measuring Autonomy

Agentic AI is operational infrastructure in 2026. This index measures it the way banks measure capital and credit: a six-dimension readiness score across autonomy tiers, the control plane, regulatory evidence, unit economics, organisational readiness, and global regulatory alignment.

持续在线的 CIB：网络恢复、回退轨道与抗量子司库

企业与投资银行已将网络恢复、跨 RTGS、即时与代币化网络的 ISO 20022 回退轨道，以及抗量子司库控制视为同一个持续在线的运营模型——这是面对 DORA 第 5 条与第 6 条、FHE、QKD 与 PQC 原语，以及 ICT 第三方集中度风险的董事会级别答卷。

2026 年后量子银行韧性指数：EO 14409、全球期限与受托密码敏捷性

行政命令 EO 14409、ANSSI 的 2030 年硬性期限与 DORA 第 5 条，已将后量子密码学从一项远期技术目标推向一项现行的监管强制要求。本指数把保护登记系统、高频账本与 SWIFT 通道的工作，转化为面向董事会的 0–5 级记分卡，使 ML-KEM、ML-DSA 和 SLH-DSA 原语与受托责任及资产负债表风险对齐。
