“The acquisition of StoneCastle is a key advancement in our strategy to assist financial institutions in optimizing their balance sheets. This will allow them to do more for the communities they serve.”

In addition to conventional deposit management, StoneCastle’s platform fits into Fiserv’s growing emphasis on digital assets. One of the Great examples of this is the FIUSD stablecoin. Through the combination of insured deposit solutions with stablecoin issuance infrastructure. Fiserv seeks to enable financial institutions to efficiently manage cash reserves collateralizing digital currencies.
Takis Georgakopoulos, Fiserv’s Chief Operating Officer, said:
“We are convinced this again positions Fiserv as a leader in core banking by allowing institutions to custody cash backing FIUSD stablecoins, while creating new value and driving innovation through the financial ecosystem.”
