Binance plans to stop supporting the world's second biggest stablecoin USDC and convert users' USDC, USDP, and TUSD into its own stablecoin BUSD on September 29

Context & Ripple Effects
Binance's conversion policy concentrated several stablecoin balances into BUSD at the exchange level. That concentration later proved dependent on BUSD's issuer: Binance wound down BUSD support after Paxos stopped minting it following an NYDFS order.
The subsequent arc reversed the original positioning. Binance later partnered with Circle to expand USDC trading pairs and add USDC to its treasury, making the earlier conversion policy a useful marker of how quickly exchange stablecoin preferences can change.
First-order effects
- Binance users holding USDC, USDP, or TUSD face conversion of those balances into BUSD, while BUSD becomes the exchange's default stablecoin balance for those assets.
- Circle, Paxos, and TrustToken lose direct stablecoin balances on Binance as the exchange redirects their users' holdings toward BUSD.
Second-order effects
- BUSD gains concentrated on-exchange liquidity and usage, while USDC, USDP, and TUSD must rely on other venues to preserve exchange-based demand.
- The move gives Binance greater control over which stablecoin pairs and balances its customers use, increasing the value of issuer alignment with the exchange.
Third-order effects
- The later BUSD wind-down after Paxos ceased minting shows that an exchange-led stablecoin distribution strategy is constrained by the issuer's regulatory position, not just trading liquidity.
- Binance's later partnership with Circle to promote USDC points to a market where stablecoin access is increasingly organized through exchange–issuer partnerships rather than permanent exchange preference for one token.
The trend: Stablecoin distribution is becoming more dependent on exchange–issuer partnerships and the regulatory durability of the issuer behind each token.
