The pressure building on commercial banks today comes from several directions at once. Corporate treasurers are younger, more digitally native, and less tolerant of manual reconciliation. Business structures are more complex: A franchisee group running fifty locations needs fifty entities managed cleanly, not fifty separate bank accounts generating a month's worth of reconciliation work. And the banking core, the ledger system that underpins it all, was never designed to flex at this pace.

The standard prescription for this problem is core replacement. However, banks are increasingly moving toward augmentation. Rather than replacing the core, banks are building around it, layering modern infrastructure above it to deliver capabilities the core was never meant to provide.

Huntington National Bank's connected deposits product, built in partnership with payments infrastructure provider Qolo, is one example of that approach in practice. For Deepak Kapoor, Huntington's H ead of Payment Products, the realization was straightforward: "We quickly realized we don't have all the Lego pieces in place to build the card that we want to build, and the ledger and the virtual account provide us with that missing Lego piece that we needed."

The result is a virtual account structure that sits above the core and behaves, externally, like a real bank account, complete with routing numbers, inbound wires, and automated reconciliation, without requiring banks to touch the underlying system of record.
