[!info] TL;DR The reserve provisions of HKMA’s 2025-08 stablecoin legislation constitute Asia’s first stablecoin reserve framework aligned with the Basel III FRTB (Fundamental Review of the Trading Book) standard. Core requirements: 100% 1: 1 fiat reserve + Tier 1 assets (HKD/USD short-term government bonds + HKMA deposits) + third-party custody + monthly audit + paid-up capital HKD 100M+. Together with GENIUS §501 (≤93 -day T-bills) + MiCA EMT (≥30% bank deposits), these form the third differentiating coordinate in the three-circle architecture.

Key facts

  • HKMA stablecoin legislation: Stablecoin Ordinance adopted 2025-08
  • Capital threshold: HKD 100M+ (materially higher than MAS S$5M / MiCA EMT minimum capital €350K)
  • Reserve bond maturity: ≤1 years (intermediate between GENIUS 93 days and MiCA’s no restriction)
  • Tier 1 stringency: aligned with Basel III FRTB Standardised Approach · first in Asia
  • 100% 1: 1 fiat reserve (HKD-pegged or USD-pegged)
  • Independent third-party custody (licensed TCSP/Trust) + monthly audit + quarterly public disclosure
  • Bankruptcy-remote segregation
  • e-CNY boundary demarcation: mainland China retail customers not accepted · hard political-balance clause

Mechanism / How it works

Core of the HKMA stablecoin reserve: 100% 1: 1 fiat reserve (HKD / USD pegged) + Tier 1 asset composition (HKD cash + HKMA central-bank deposits + HKD/USD short-term government bonds ≤1 years + limited proportion of commercial paper) + independent third-party custody (licensed TCSP/Trust) + monthly audit + quarterly public disclosure + bankruptcy-remote segregation + HKD 100M+ paid-up capital.

FRTB connection: HKMA treats stablecoin reserves as analogous to bank trading-book assets → applies Basel III FRTB Standardised Approach (SA). Market-risk capital calculation covers: interest rate risk + currency risk + credit spread risk. This is the world’s first regulatory design explicitly incorporating stablecoin reserves into the Basel capital framework. The implied USDC-vs-USDT premium logic arising from capital calculation flowing through to the bank end is addressed in Basel III FRTB Strategic Implications · USDC's Implicit Capital Premium + BUIDL's Bank Channel.

Origin & evolution

HKMA initiated stablecoin consultation in 2022-12 ; the second consultation paper in 2023-12 established a sandbox (ZA Bank / Standard Chartered / HSBC / Animoca × HKT consortium); the Stablecoin Ordinance was adopted in 2025-08 . In 2026-04 , HKMA’s Consultation Paper “Capital treatment for licensed stablecoins” directly cited BCBS SCO60 as the parent standard. First licence decision 2026-05-21: of 9 社 applications, only 2 件 were in fact approved (HSBC + StanChart Anchorpoint); for strategic implications see HKMA License Strategic Implications · Tether HK Asymmetric Bet + Mainland China SC Channel.
