Deposited stablecoins are automatically converted into U.S. dollars and credited to users’ brokerage accounts, enabling them to begin trading almost immediately. Interactive Brokers also revealed plans to add support for Ripple USD (RLUSD) and PayPal USD (PYUSD) as early as next week.
Stablecoins target cross-border funding bottlenecks
According to Interactive Brokers, the move is aimed at addressing what it describes as a “critical pain point” for international investors: slow, expensive cross-border funding via traditional bank wires.
Unlike fiat transfers that can take days and are limited by banking hours, stablecoin deposits offer near-instant settlement and lower transaction costs.
“Stablecoin funding provides international investors with the speed and flexibility required in today’s markets,”
said Interactive Brokers CEO Milan Galik, noting that clients can transfer funds and start trading within minutes.
The company first introduced USDC funding for retail brokerage accounts in December and had reportedly considered launching its own stablecoin earlier this year.
Growing stablecoin adoption reshapes financial markets
Interactive Brokers entered the crypto space in 2021, initially supporting trading in Bitcoin and Ether. Its digital asset lineup expanded in 2025 to include tokens such as Solana and XRP.
The expansion comes amid rapid growth in the stablecoin sector. Throughout 2025, stablecoins gained traction among governments, financial institutions, and fintech firms exploring blockchain-based payments and settlement.
The stablecoin market surpassed $300 billion in total capitalization for the first time in October, driven largely by USDT, USDC, and Ethena Labs’ USDe. As of Friday, the sector’s total market value stands above $310 billion, according to data from DefiLlama.
