Interchange origins and future winners
The future of interchange
The financial crisis created demand for a new kind of bank before fintech had the infrastructure to supply it. After 2008, younger consumers were more willing to move paychecks and daily spending away from big banks they no longer trusted, and many were less interested in revolving credit card debt. That combination made debit first products like Chime especially powerful, because a clean app, early paycheck access, and a free card could win primary account status and turn everyday spending into interchange revenue.

The key behavioral shift was not just anger at banks, it was openness to changing the default account where money landed. Once paychecks flowed into a neobank account, groceries, gas, and bill pay followed, which is how consumer distrust translated into a large recurring interchange stream.

The crisis also weakened the appeal of traditional credit for younger users. That left room for debit led neobanks on one side, and BNPL products like Afterpay, Affirm, and Klarna on the other, each serving consumers who still needed to spend but wanted alternatives to classic credit cards.
-
This only became a venture scale business because the post crisis demand met a post crisis supply stack. Sponsor banks, processors, and BaaS platforms let startups launch branded accounts and cards quickly, then keep a meaningful share of interchange while banks and networks took the rest.
Going forward, the same crisis era distrust matters less than product depth. The winners will be the companies that first used debit and interchange to acquire customers, then layered on credit, lending, and software to raise revenue per user. Interchange opened the door, but multi product financial relationships will define the next phase.
