Singapore stablecoin rules tighten: 100% backing, no interest

Singapore's Monetary Authority of Singapore (MAS) has finalized tighter rules for stablecoins under its regulatory framework. The two core requirements: issuers must hold 100% asset backing at all times, and they are banned from paying interest to stablecoin holders. Separately, MAS is now weighing whether to recognize certain foreign-issued or jointly issued cross-border stablecoins within the same framework, a reversal from its earlier position that restricted recognition to domestically issued coins only.

The interest ban is the sharper edge here. Several APAC crypto platforms had been designing or piloting yield-bearing stablecoin products, where the issuer deploys reserve assets into low-risk instruments and passes some return to holders. That model is now closed for any MAS-regulated issuer.

The 100% backing requirement eliminates fractional reserve approaches and rules out reserve structures that rely on riskier or less liquid assets to generate returns. Issuers must hold high-quality, liquid assets equal to the full value of coins in circulation.

For the broader APAC stablecoin market, Singapore's rules set a compliance floor that will influence how counterparties across the region structure their products. Singapore is the dominant crypto hub in Southeast Asia. When MAS moves, other regulators and institutional players take note.
