The company also reported a small mark-to-market loss on its U.S. government securities portfolio for the quarter. Its internal currency basket, known as the GLOBAL, declined slightly during both the month and the quarter.

Execution data showed the average U.S. stock trade size remained elevated in March. The firm said the “total cost of executing and clearing U.S. Reg.-NMS stocks” for its professional clients was low, measured against a VWAP benchmark, with a similarly modest cost over the longer term.

Broker Integrates Digital Assets Multi-Platform

Beyond traditional securities, Interactive Brokers has also been expanding its platform to include digital assets. The broker has made crypto-asset trading available to eligible individual investors in the European Economic Area through Interactive Brokers Ireland Limited, an authorised crypto-asset provider.

The platform supports 11 crypto-assets alongside stocks, options, futures, currencies, bonds, and mutual funds. The firm said the launch is intended to simplify trading and improve transparency.

Clients can now transfer existing cryptocurrency holdings into accounts linked to the platform, allowing trading of digital assets without prior liquidation. The broker has gradually expanded its crypto offering over recent years, including launches via Paxos and in the UK, integrating digital assets into its broader multi-asset platform.
