Santander Private Banking International, a division of Banco Santander, is now offering cryptocurrency trading and investment services to its affluent clients in Switzerland. The bank will expand its crypto offerings based on a stringent screening process and provide a regulated custody model for asset security. This move is a departure from the typical stance of large banks on cryptocurrencies. Santander's private banking sector manages assets for approximately 210,000 high-net-worth individuals, with total assets and deposits around $315 billion.
