Circle launches StableFX for sub-second, 24/7 on-chain FX settlement
Circle launched StableFX in November 2025 on its Arc blockchain to enable sub-second, 24/7 on-chain foreign exchange settlement using stablecoin pairs such as USDC/EURC, aiming to eliminate prefunding and T+1 delays. StableFX uses Request-for-Quote (RFQ) execution from multiple liquidity providers and atomic payment‑versus‑payment (PvP) settlement to compress traditional T+1/T+2 cycles into sub-second finality, requiring no prefunding or bilateral agreements and promising greater capital efficiency for treasuries, payments and commerce.
The initiative integrates with Circle’s Cross‑Chain Transfer Protocol (CCTP), Gateway APIs and wallet interfaces so FX flows can be embedded directly into applications. Circle also launched a Partner Stablecoins program to support regional issuers from Japan, Brazil, South Korea, the Philippines, Australia and South Africa; CEO Jeremy Allaire said the firm is "leaning in hard on helping quality stablecoins launch" to build foundations for global commerce and finance.
Early adoption signals include Japan’s approval of USDC in March 2025 via a joint venture with SBI Holdings and integration of Japanese stablecoin JPYC for low‑cost yen‑USDC swaps. The report notes emerging‑market interest in using stablecoins for trade tokenization and FX hedging, and cites regulatory moves such as the US GENIUS Act and Circle’s IPO as supportive factors for uptake.
