StoneX Completes RJ O’Brien Acquisition

StoneX has completed the acquisition of US clearing broker RJ O’Brien & Associates (RJO) according to a story in The Trade news. The firm initially announced the acquisition in April 2025, which is set to make StoneX the largest non-bank futures commission merchant (FCM) in the US and support the firm in its goal to provide greater access to liquidity in fixed income markets. Through the acquisition, RJO’s clients will gain access to a wide range of markets, products and services such as StoneX’s over the counter (OTC) hedging platform and liquidity across fixed income products. “This transaction significantly expands our scale and increases our capabilities in several critical areas, including through a materially expanded client network and the addition of the leading introducing broker business,” said Philip Smith, chief executive of StoneX.
