Client Connect 2025: takeaways from connecting the world's largest merchants. CMSPI's second annual Client Connect conference provided two days of high-impact insights focused on one thing: connecting the dots across the merchant payments landscape. From macroeconomic trends and data challenges to innovations like PINless routing and agentic commerce, the event emphasized the power of collaboration, unified data, and policy for merchants. Four data points to take into 2026. CMSPI's Client Connect 2025 brought together leading merchants, payments experts, and policy stakeholders at The Whitley Hotel in Atlanta for two days of collaborative discussion and strategic insight. With a focus on payments optimization, the event highlighted the rising complexity of the payments industry and the critical role of data, innovation, and policy in driving merchant outcomes. Amidst all the insights from speakers, panelists, and attendees, four statistics stood out that are shaping merchants' payments strategies into 2026. 1. $236 billion in estimated card fees: why fragmented data is costing merchants record-highs. Sitting in a room with the world's most sophisticated merchants, one theme was unmistakable: data isn't just a tool - it's the foundation. From macroeconomic trends to transaction-level analytics, the message was clear. CMSPI's Callum Godwin and James Schaefer unpacked how high-rewards card usage, rising network fees, and increased card-not-present (CNP) spend are driving higher card fees - now totaling $236 billion in the U.S. (Figure 1). But the real challenge lies in fragmented data. As speakers showcased in "Mind the Data Gap," merchants need unified models to unlock insights across the transaction lifecycle - from authorizations to approvals to chargebacks. Without it, optimization is guesswork. 2. $3 billion in estimated CNP PINless savings[2]: why merchant collaboration is essential. One of the most powerful themes to emerge from Client Connect 2025 was the transformative impact of collaboration across the payments industry. Sitting alongside some of the world's most sophisticated merchants, it became clear that no single stakeholder - be it issuer, acquirer, or merchant - can optimize in isolation. In the "Turning Up the Heat on PINless" and "Routing Realities" sessions, CMS Payments Intelligence Inc. saw how strategic debit routing and PINless enablement (Figure 2) can unlock over $3 billion in estimated annual savings. But the real driver of savings isn't just technical - it's relational. Case studies showed that when merchants work closely with networks and processors, they improve not just cost efficiency but also network availability and transaction performance. Collaboration isn't a nice-to-have; it's a competitive advantage. This was echoed in "Breaking Down Silos: Approval Strategies," where CMS Payments Intelligence Inc. tackled the challenge of authorization rate optimization. The takeaway? Transparency and shared data between issuers, merchants, and acquirers are essential. Everyone wants to approve legitimate transactions - but without a shared strategy, friction persists. Figure 2.

From agentic commerce to stablecoins and open banking, the future of payments is being shaped by rapid innovation. But sitting in sessions like "The Future of Payments" and its breakout on agent-led commerce, one thing became clear: innovation must be approached with precision, not hype. Merchants are eager to explore new tools - but they're also wary. Despite advancements in fraud prevention, ecommerce losses are estimated to exceed $200 billion globally in 2024 (Figure 3), with over 3% of ecommerce revenue lost to fraud.[4] That's a sobering reminder that despite significant improvements in innovation, there's still a long road ahead to 'optimal'. The promise of agentic shoppers or stablecoin-based payments is real, but so are the risks around governance, liability, and consumer protection. 4. Up to $12 billion in estimated debit savings[6]: how policy can reshape payments. Policy certainly doesn't move as fast as solutions in stablecoin or agentic commerce, but it does set the rules of the game and the foundations of innovation. At Client Connect 2025, the "Making Sense of Policy Change" panel made clear that regulatory shifts can unlock billions in merchant savings, but only if merchants are engaged and understand their data. CMS Payments Intelligence Inc. explored the implications of Regulation II, the Credit Card Competition Act, and state-level advocacy. CMSPI's data showed that merchants could save nearly $4 billion annually if the regulated debit interchange cap were lowered to the proposed rate - and over $12 billion if it were aligned with the transaction-weighted average authorization, clearing, and settlement (ACS) cost (Figure 4). But policy doesn't operate in a vacuum. In "Policy in Payment Modernization," CMS Payments Intelligence Inc. discussed how regulation must evolve alongside technology. Whether it's stablecoins, agentic commerce, or open banking, the challenge is ensuring that innovation is shaped by principles of safety, fairness, and consumer protection. For merchants, the takeaway is simple: policy is not just a backdrop - it's a lever to deliver optimal outcomes. Figure 4. Estimated Annual Costs for U.S. Merchants of Various Debit Interchange Caps (data as of 2021)[7] Client Connect 2025 made one thing clear: payments optimization is a journey that requires precision, partnership, and data.

Martha Southall, Global Director of Client Insights at CMSPI, discusses the main drivers behind the new generation of domestic card payment schemes. Laser in Ireland, pankkikortti in Finland, PIN in the Netherlands, and Bancomat in Luxembourg have two things in common. They were all domestic card schemes, and they were all abandoned between 2011 and 2015. In their absence, the processing of domestic card payments often shifted further towards the major international card brands. However, the last decade has seen countries – including Russia, Turkey, and Nigeria – introduce their own schemes, while others are now exploring the option. But who are these new schemes, and what is driving their development?
