Monex Group Acquires 20% Stake in Westfield Capital Management

Japan’s Monex Group, a financial services conglomerate with operations spanning online brokerage, cryptocurrency exchange, and asset management, has expanded its portfolio with a strategic investment in U.S.-based Westfield Capital Management. The Tokyo-listed firm will acquire a 20% stake in the Boston boutique asset manager through a special purpose vehicle, marking its latest move to diversify its investment capabilities.

Westfield, founded in 1989, brings three decades of growth equity expertise to Monex’s global financial ecosystem. The deal signals Japanese financial institutions’ growing appetite for international partnerships amid increasing institutional adoption of alternative assets—including cryptocurrency ventures where Monex has been actively expanding through its crypto exchange operations.
