Debit Network Control: The Battleground Is No Longer Just Rates

Debit networks are being reshaped by a combination of regulation, shifting transaction mix, and intensifying competition in digital payments. While traditional debit economics have been anchored in regulated interchange and PIN-based, in-person transactions, growth in e-commerce and digital wallets is accelerating the importance of card-not-present (CNP) debit. At the same time, routing reforms have expanded competition into CNP environments, allowing networks historically focused on single-message debit to compete more directly with global networks. This has shifted competition away from pure interchange economics toward capabilities like routing optimization, fraud detection, tokenization, and merchant acceptance performance.

Key questions discussed in this report: 

• What debit networks are competing in the U.S. and what are their differentiators?
• How are debit networks competing differently now in light of changes to the Durbin Amendment?
• What will matter most for debit networks as more payments move to e-commerce and digital wallets?
