[!info] TL;DR First Digital USD (FDUSD) is issued by Hong Kong’s First Digital Trust, launched in 2023-06 as a replacement for BUSD (halted by NY DFS) and positioned as Binance’s primary trading pair, with market cap of ~$3B in 2026-Q1. FDT is one of HKMA’s nine first-phase stablecoin licence applicants, filing in 2025-08, but due to the reserve controversy involving Justin Sun-related entities (2024-12 The Block investigation + 2025-Q1 temporary depeg), HKMA required FDT to sever ties with Sun; the licence was pushed to 2026-Q3. FDUSD is the highest-volume sample of the Asia-Pacific “grey zone → white zone” transition, and a live stress test of HKMA’s licence template.

Mechanism / How it works

FDUSD’s core positioning is the only stablecoin deeply tied to Binance. After Binance exited BUSD in 2023-08, following the NY DFS order for Paxos to stop BUSD issuance, it rapidly installed FDUSD as the primary trading-pair anchor. This drove rapid growth, from zero to $3B in under two years, but also created a “single-distributor over-dependence” risk: Binance holds 50%+ of FDUSD’s circulation and 70%+ of its trading volume. Unlike the PYUSD/USDC distribution-incentive model, FDT has not publicly disclosed its interest-sharing ratio with Binance, but market speculation holds that Binance receives a non-interest subsidy in the form of “market-maker preferential treatment + priority listing rights” — the exact inverse of the distribution boundary depicted in the issuer-distributor 50/50 model. HKMA’s licence pathway made FDUSD the first large-scale case of a “grey zone → white zone” transition, contrasting with USDT’s choice to remain in the grey zone.
