StoneX Group Inc (NASDAQ:SNEX) has announced that the City Index UK retail brokerage brand will retire on September 12, 2026, with all new account openings moving to the newly branded StoneX Trading.
The rebranding follows StoneX Group's 2020 acquisition of City Index's parent company, Gain Capital, which had previously acquired City Index in 2015. StoneX Trading aims to provide retail traders with enhanced access to market insights and the global expertise of StoneX, a Fortune 50 financial services company with over 80 offices worldwide.
Existing City Index clients will continue trading on the same platforms with unchanged accounts and support teams during and after the transition. The new StoneX Trading website is already live, featuring updated branding and client experience across digital channels and mobile applications.
StoneX Group emphasized that the move aligns the retail brokerage with its broader global financial services franchise, serving commercial, institutional, payments, and self-directed clients. Company executives highlighted the continuity for clients and the expanded capabilities brought by the StoneX brand.
