Singapore publishes quantum-safe migration targets

CSA sets out planning by end-2027, a CII migration target in 2031 and encouraged migration by 2035 for other quantum-exposed organisations.

CSA sets out planning by end-2027, a CII migration target in 2031 and encouraged migration by 2035 for other quantum-exposed organisations.

The October 14 advisory adds dated milestones to Singapore’s readiness framework. CII owners should continue consulting the separate June 2026 CII guidance; MAS financial-sector supervisory guidance remains a distinct instrument.

What it means for your migration
  • Use the planning milestone for cryptographic inventory and supplier engagement; distinguish CII targets from encouraged wider-organisation migration.

Guidance is not an identical statutory deadline for every organisation.
