OKX to disable trade with USDC on USDT/USD spot pair

Summary

OKX will stop allowing new spot orders on the USDT/USD pair that trade using USDC, starting 20 May 2026 at 17:00 (UTC+8).
Orders on USDT/USD using USD, USDG or RLUSD will still work, and your existing balances in USDT, USDC, USDG, RLUSD and USD are not affected.
Open spot orders placed before the change stay active and can still be amended, cancelled or filled, but untriggered strategy orders and active trading bots that use USDC will be cancelled or stopped by the system at that time.
If you trade USDT and USDC, use the USDC-USDT standalone pair instead, and move any USDC-based strategy orders or bots to USD, USDG, RLUSD or that pair before the deadline; contact OKX Customer Support if you need help.
