Singapore’s Monetary Authority of Singapore (MAS) is making synthetic data the default for regulatory technology (RegTech) sandbox pilots. Banks now have a hard migration deadline—Q2 2026—to move existing sandbox testing environments off real customer data.
MAS mandates synthetic data for RegTech sandbox pilots, with a Q2 2026 migration deadline
Singapore’s Monetary Authority of Singapore (MAS) has announced that financial institutions participating in RegTech pilot programs under its Regulatory Sandbox initiative must use synthetic data for testing. The requirement applies to banks’ sandbox testing environments and is positioned as part of the MAS Regulatory Sandbox 3.0 approach to enabling experimentation while maintaining compliance expectations.
MAS is also setting an implementation timeline: institutions are required to migrate existing sandbox testing environments to synthetic data by Q2 2026. The policy is framed as a privacy and compliance measure that reduces exposure of customer data during testing and pilot work, while still allowing institutions to validate RegTech concepts in a controlled setting. The framework is also described as a potential model for other Asian financial regulators, given Singapore’s role as a regional regulatory bellwether.
- Data engineering: Banks will need production-grade synthetic data pipelines (generation, refresh cadence, lineage, access controls) that can support iterative sandbox testing without quietly reintroducing real data “exceptions.”
- Privacy & assurance: “Synthetic” won’t be enough on its own—teams will need a repeatable way to validate re-identification risk and document governance so the sandbox remains demonstrably lower-risk than customer-data replicas.
- Model risk meets compliance: RegTech pilots often test detection and reporting logic; maintaining utility (edge cases, rare events, correlations) while meeting MAS expectations will push teams toward measurable utility and privacy acceptance criteria.
- Regional signal: If MAS’s approach becomes a reference point, multi-jurisdiction banks may want to standardize synthetic-data controls now to avoid rework when similar sandbox rules appear elsewhere in Asia.
