Through the partnership, TNS users will be able to gain direct access to TFX, allowing both domestic and international firms to make use of trading connectivity in Japan through a single provider.
The move now completes TNS’ full suite of services in Japan, spanning hosting data and connectivity.
“Partnering with TNS opens new doors for TFX by providing exposure to its robust network of global market participants,” said Ryosuke Seo, director of wholesale business department at TFX.
“This collaboration positions TFX to expand its international footprint and deliver greater access and efficiency to traders worldwide.”
The addition of TFX expands the firm’s exchange portfolio, including Japannext and the Japan Exchange Group, the latter which encompasses the Tokyo Stock Exchange (TSE), Osaka Exchange (OSE) and Tokyo Commodity Exchange (TOCOM) under its umbrella.
Jeff Mezger, vice president of product management at TNS, said: “Completing our coverage across all Japanese exchanges is a milestone that strengthens our offering in one of the world’s largest financial centers.”
“This expansion further cements TNS as a one-stop shop for global trading access.”
The partnership highlights TNS’ aim to continue investment into the APAC region. The firm initially expanded into the markets in 2020, providing clients with access to equities, commodities, fixed income and currency markets coverage from Hong Kong Exchanges and Clearing (HKEX).
In addition, the firm has increasingly enhanced its global offering in recent months, and in July 2025, TNS added six Latin American equities and derivatives exchanges to its network.
The offering makes use of the nuam exchange access point in Santiago to connect to markets in Chile, Peru and Colombia.
