Santander has produced a rare combination in global private banking for high-net-worth (HNW) clients: rapid growth, seamless cross-border services and outstanding efficiency. What is more, the Madrid-based bank has transformed a dense regional footprint into a coordinated global platform suited to internationally minded clientele.
It helps that Santander has the numbers to prove this narrative. Client assets and liabilities reached a record $397 billion as of June 2025, up 17% year-on-year, reinforced by the strength of its net new money and one of the most efficient cost-to-income ratios in the entire private banking industry.
