Interactive Brokers Adds 24/7 Stablecoin Funding for Eligible Clients

Interactive Brokers said eligible clients of Interactive Brokers LLC can now fund brokerage accounts with stablecoin, adding a 24/7 deposit option that operates outside normal banking hours. In its January 15 announcement, the broker said clients can send USDC from a crypto wallet, have it converted automatically into U.S. dollars, and begin trading across its platform within minutes.

According to the company, the new funding route is designed to address a familiar problem for global traders: slow and expensive cross-border wires. Interactive Brokers said it will not charge its own fee for stablecoin deposits, although clients still face blockchain-network charges and a 0.30% conversion fee from zerohash, with a $1 minimum.

The broker also said stablecoin funding is available only to eligible clients and that support for RLUSD and PYUSD was expected to follow. That means the feature is best understood as a funding and account-access update, not a broader shift in what products clients can trade.

Why it matters

For traders who move capital frequently, funding speed can matter just as much as spreads. A 24/7 deposit rail can reduce delays before major market events and gives internationally based clients another way to avoid wire cut-off times, weekend gaps, or costly correspondent-bank transfers.

What to watch next

The practical question is how widely the feature rolls out across jurisdictions and whether rival multi-asset brokers answer with similar always-on funding options. Traders should also watch the total cost stack, including wallet fees, conversion charges, and any limits tied to account eligibility.
