The Monetary Authority of Singapore proposed allowing some permissionless-blockchain crypto assets to receive lower-risk Group 1 treatment, while capping Singapore-incorporated banks' exposure at 2% of Tier 1 capital. The consultation paper would move away from treating public-chain assets as uniformly high-risk Group 2 assets if they meet principle-based requirements. If the issuance is also a bank liability, the issuance size would be capped at 5% of Tier 1 capital.
