South Street Securities has completed its merger with GX2 Spread Markets, after receiving regulatory approval from the Financial Industry Regulatory Authority (FINRA) and the National Futures Association (NFA).
The two broker-dealers are now consolidated under the South Street Securities entity, as GX2 Spread Markets transitions the operation of its interest rate algorithmic trading platform for outright, spread, and basis strategies into South Street Securities.
James Tabacchi, president and CEO of South Street Securities Holdings, comments: “Bringing GX2 Spread Markets into South Street Securities represents the next chapter in our mission to scale strategically while honouring our standard of quality, relationship-driven service.”
This follows an announcement from January 2024 of South Street Securities Holdings acquiring GX2 Spread Markets, the broker-dealer, as well as GX2 Systems, a fintech firm that engineers electronic trading solutions for the fixed income and futures markets.
GX2 Systems continues to design, develop, and deploy new execution algorithms and strategies, while aiming to improve customer access to execution through web application and API.
The experienced team at GX2 Systems will help expand South Street Securities’ footprint in the primary dealer, large international dealer, and hedge fund ecosystem, according to the firm.
David Jaberg, president and CEO of GX2 Systems, says: “Joining forces under one broker-dealer unlocks new opportunities for our team and clients.
“It allows us to emphasise the growth of our voice execution desk and client coverage by utilising the latest technology developments and improvements within our global, algorithmic execution platform.”
