UMB Institutional Custody Reaches $239 Billion as Client Base Diversifies

UMB Bank’s institutional custody business reached $239 billion in assets under custody at December 31, 2025, according to a leadership profile published on April 15, 2026. Amy Small, executive vice president and executive director of institutional custody, described growth from a $60 billion base and a broader client mix.

Small said custody had operated as an add-on to UMB Fund Services before 2018, when the opportunity to develop a standalone business emerged. Mutual funds now represented 30% of the custody business described in the profile, with alternative investments, government, insurance and corporate clients making up the remainder.

She identified increasingly complex government portfolios as one source of demand. Services discussed include risk and performance reporting, compliance monitoring, collateral management and support for treasury and liquidity. For insurers, she highlighted alternative-asset servicing, foreign exchange and regulatory reporting.
