Fiserv has completed its acquisition of StoneCastle Cash Management, strengthening its portfolio of insured deposit, liquidity, and digital asset solutions for financial institutions while introducing new FDIC-insured liquidity options for merchants. By integrating StoneCastle’s institutional deposit network with the broader Fiserv ecosystem—including core account processing, digital banking, and payments platforms—the company is creating a differentiated, technology-driven offering to help banks optimize liquidity, strengthen balance sheets, and access diversified funding sources, including reserves linked to digital assets and FIUSD stablecoin issuance.

Merchants gain enhanced cash management and investment alternatives designed to improve financial flexibility, offset acquiring costs, and support growth, while existing StoneCastle clients such as wealth managers benefit from expanded access through Fiserv’s extensive banking relationships. “This acquisition highlights Fiserv’s unique position at the intersection of banking and commerce: for banks, it provides a new, stable deposit source; for Merchant clients, including our Clover merchants, it provides a safe, high-yielding alternative to manage their operating cash,” said Takis Georgakopoulos, Co-President at Fiserv. The transaction closed after regulatory approvals, with financial terms undisclosed.
