According to Bloomberg’s report today (12), the large US online broker Interactive Brokers (IBKR) has officially launched a stablecoin deposit feature, allowing retail investors worldwide to fund their securities accounts directly from cryptocurrency wallets with stablecoins. Funds can arrive in seconds, enabling 24/7 real-time deposits and significantly reducing the time and fees associated with traditional bank wire transfers.

The report further states that a IBKR spokesperson confirmed via email that this service will be rolled out in phases, initially opening to some qualified US clients (mainly retail investors who have completed KYC verification); later, it will gradually expand to more countries and user groups. IBKR said that as the service goes live, detailed procedures and tutorials will be announced on the official website, app, and customer portal.

Initially supporting stablecoin USDC

It is worth noting that, in fact, stabledash reported as early as December 10 that cryptocurrency infrastructure provider Zero Hash demonstrated IBKR’s stablecoin deposit interface via the X platform. According to their demo, IBKR already supports Circle’s USD stablecoin USDC, and transfers can be made through the Ethereum, Base, and Solana main blockchains.

The technical support behind this feature is entirely provided by Zero Hash, ensuring rapid settlement of funds.

In fact, this service has been in planning for some time. In July 2025, IBKR founder and chairman Thomas Peterffy publicly stated that the company was actively evaluating the feasibility of using stablecoins as a funding channel for accounts. Now, only five months later, it is officially launched, indicating that traditional brokers’ adoption of crypto assets is advancing much faster than market expectations.
