The slow death of interchange as a standalone growth engine

    Interchange gets your foot in the door, but software, services, and recurring relationships keep it open.


    Interchange – the small fee collected on every card transaction – has been payments-first fintech’s easiest and most dependable source of revenue. Invisible to users, scalable at high volume, and seemingly recession‑resistant, it was the low‑hanging fruit of payments economics. It gave even a brand-new card startup a revenue stream from day one.

    But the narrative has evolved today. Interchange still matters, but less as a growth driver. It’s becoming infrastructure: a cost of entry that enables transaction flow, but not the sole source of meaningful value creation. This transition is most evident in the financial filings, quarterly segment reporting, and investor focus of leading payments players such as Block, PayPal, and Shopify.

    These firms generate significant revenue from payments, but are increasingly emphasizing monetization beyond interchange. The message to the market is clear: Interchange gets your foot in the door, but what you do with the customer afterward matters more to the business.

    Block: Stacking revenue above the interchange tollbooth

    Payment volume and the expansion of its Bitcoin ecosystem matter to Block, but its future economics are increasingly driven by the subscription and services built on top of transaction flows.

    Broader Wall Street reactions this earnings season show investor focus on non‑transaction drivers.

    Why Payoneer wants fewer – but much larger – customers

      The end of the volume era in cross-border fintech?


      For much of its history, Payoneer was synonymous with volume: millions of accounts, tens of billions of dollars in cross‑border flows, and a global reach that connected small businesses and sellers in over 190 countries. But in the company’s latest investor presentations and financial performance commentary, especially at the March 2026 Wolfe FinTech Forum, there’s a different emphasis slipping into the language and the numbers. The story is now about value per customer and lasting economic returns.

      Last week, we discussed that analysts observed a similar theme in Block and Chime’s Q4 2025 results: both companies’ narratives emphasized prioritizing engagement over raw user counts.

      This is, in many ways, fintech’s next act: moving past the early‑stage race for signups toward a model that looks more like enterprise SaaS economics than traditional payments volume.

      More than Metrics: What’s changing at Payoneer

      At the Wolfe FinTech Forum in New York this week, Payoneer’s leadership laid out a vision that read more like a guide to sustainable, profitable fintech than ‘growth at any cost’. The company outlined:

      Q4 2025 in Consumer Finance: Fintechs move from user counts to dollars per engaged customer

        As engagement becomes currency, AI and disciplined growth are setting a new standard of what winning looks like.


        Late February 2026, Block and Chime reported their Q4 2025 results.

        The numbers illustrate that Block is leveraging AI and a leaner workforce to drive efficiency and monetize its most engaged users, while Chime is doubling down on multi-product adoption and responsible credit growth to strengthen its platform.

        Block: A pivot toward AI, efficiency, and high-value engagement

        Block’s Q4 2025 earnings drew attention for the metrics but also for the signals woven within them.

        The company reported: 

        • $2.87 billion in gross profit, up 24% year-over-year, alongside adjusted operating income of $588 million, a 46% increase, and adjusted EPS growth of 38%. 
        • Cash App, the consumer-facing engine, ended the year with 59 million monthly active users, with primary banking actives growing 22%, a cohort that company executives framed as the real driver of profitability. 
        • Square, the merchant services arm, saw its gross payment volume rise 10.3% year-over-year in Q4 2025.

        But the quarter’s more defining news was the nearly 40% workforce reduction, cutting headcount from over 10,000 to under 6,000 employees. Co-founder and CEO Jack Dorsey characterized the move as “functionalizing the company.” 

        “Intelligence tools have changed what it means to build and run a company… a significantly smaller team using these tools can do more and do it better,” he said in a letter he published on X (formerly Twitter) announcing Block’s workforce reduction. 

        The layoffs were tightly linked to AI integration, designed to create leaner teams capable of faster product delivery, personalized customer experiences, and higher engagement-driven profitability.

        Yet some industry observers believe that Block’s reliance on AI as the primary efficiency narrative may oversimplify the story. The firm’s prior ambitious hiring and the expensive Afterpay acquisition continue to weigh on the balance sheet, suggesting that AI-driven efficiency may only be one piece of a broader puzzle that includes past overextension and capital intensity.

        Coinbase rides the waves of stress and opportunity with its ‘Everything Exchange’ vision

          Coinbase is trying to bridge two financial worlds: crypto and traditional finance, while navigating the challenges of public policy.


          Coinbase [NASDAQ: COIN] is outgrowing its early role as a simple crypto exchange.

          Recent moves suggest that the firm is evolving into a unified platform for multiple financial assets and services, positioning itself as a bridge between traditional finance and the digital asset economy. This transformation is guided by what the company calls its “Everything Exchange” strategy – a term it began emphasizing in late 2025 – aimed at removing boundaries between asset classes and offering trading, financial services, and developer infrastructure within a single integrated platform.

          “Our Everything Exchange vision is about removing artificial boundaries between asset classes and building for the next generation of markets,” the company noted in its recent press release.

          But broadening that scope also exposes Coinbase to new regulatory, competitive, and market pressures: the balancing acts that come with trying to be more than a crypto exchange.

          Banking: AI, automation, and the rise of digital-first scale

            The new battleground in banking is intelligent operations and scalable execution.


            In 2026, banking is about moving money smarter, faster, and with fewer humans in the middle. Across corporate finance and global retail operations, banks are experimenting with technology and operational design in ways that challenge long-held assumptions about scale, speed, and control. 

            Three recent developments exemplify what’s happening in money movement: Goldman Sachs deploying AI agents, Truist automating corporate receivables, and Nubank expanding abroad with a lean digital model. All demonstrate how the modern banking playbook is evolving.

            Case Analysis 1: Goldman Sachs’ AI agents as “digital colleagues”

            Goldman Sachs is testing a new frontier in operational finance: it’s deploying autonomous AI agents built on Anthropic’s Claude mode to enhance internal productivity and streamline workflows. These agents are undergoing trials for rule-based tasks such as transaction reconciliation, trade accounting, and client onboarding; roles that have resisted automation for decades because of high regulatory and operational complexity.

            Why some major banks are bringing embedded finance in-house

              Inside incumbent banks’ push to own the embedded finance stack

              Capital One has spent the past two years doing something unusual for many US banks: rebuilding itself in plain view.

              First came the Discover acquisition in 2024, a move widely read as a scale play that gave Capital One greater reach across credit cards, payment rails, and consumer financial infrastructure. Then came the Brex acquisition announcement in January 2026, a very different kind of asset on paper, but one that fits a similar underlying logic. 

              These deals signal that Capital One is collapsing the distance between product and distribution, software and balance sheet, embedded finance and the bank itself. This isn’t about cards. And it’s not really just about M&A. It’s about ownership.

              UBS’s US Charter: From a global wealth powerhouse into a full-service US bank

                How UBS is strengthening its operations, tech, and competitiveness in the world’s largest retail banking market.
                When you think of UBS, the Zurich-headquartered firm and one of the world’s largest wealth managers operating in over 50 countries, the first things that come to mind are exclusive clients, Swiss banking discretion, and global investment services. In January 2026, UBS Group AG, already publicly traded on the SIX and NYSE, signaled a broader ambition after receiving conditional approval from the U.S. Office of the Comptroller of the Currency (OCC) for a national bank charter. 
                The bank charter gives UBS the regulatory authority to accept deposits, expand checking accounts, and offer traditional lending products directly – a significant step beyond its historical US footprint focused on wealth and investment clients. For decades, UBS in the US operated largely as a wealth-centric entity, relying on brokerage and investment management platforms, rather than core banking relationships. With this bank charter, UBS moves into a domain where operational infrastructure, risk engines, and customer-facing technology are now mission-critical at scale.

                How a Brazilian digital bank is restructuring the fintech playbook – and why Wall Street is listening

                  From São Paulo to Wall Street…


                  When a challenger bank born in São Paulo opts for Wall Street for its IPO filing over its home turf, it raises a question no growth investor can ignore: What does it take for a digital bank from an emerging market to play on the world’s biggest stage – and what does that tell us about the future of public fintechs?
                  Agibank is the second Brazilian fintech in recent weeks to take this route, just days after PicPay, also in São Paulo, announced similar plans. These moves point to a renewed appetite among Latin American digital lenders to tap global capital markets after years of dormant IPO activity in the region.
                  But beneath the headlines, the ticker symbol AGBK, and a reported target of raising up to roughly $1 billion in proceeds, lies a deeper story about scaling fintech infrastructure, navigating risk, and building a technology platform that can serve millions without collapsing.

                  A backstory of growth and reinvention

                  Agibank didn’t start life as a fintech powerhouse. Its roots trace back to 1999, when founder Marciano Testa, then a college student, launched Agiplan as a credit distributor serving financially underserved segments – eventually evolving into Agibank and becoming fully digital in 2018.

                  When Midwest roots meet Sun Belt growth: Fifth Third’s big bet on scale and relevance

                    For Fifth Third, relevance and reach matter as much as scale.


                    In today’s age, where finance is measured by margins, scale, and digital reach, strategic positioning matters as much as legacy positioning. For Cincinnati-based Fifth Third Bank [FITB], a storied regional bank with roots extending more than a century and a half, this reality has translated into decisive action. 

                    In October 2025, the bank agreed to acquire Dallas-based Comerica Incorporated in a $10.9 billion all-stock transaction that materially expands Fifth Third’s scale, geography, and competitive posture as it enters 2026.

                    It is one of the biggest regional bank acquisitions of 2025 and carries deeper significance.

                    The deal highlights

                    At its core, the Fifth Third–Comerica transaction is simple in structure but significant in impact:

                    The Financial Evolution of 2025: AI, Crypto, and Regional Banking

                      Brains, Blockchain, and Backbone: How finance evolved in 2025


                      2025 was anything but ordinary. AI evolved from tools to agentic decision-makers. Crypto roared back and shrugged off skepticism to reclaim a seat at the table. And regional banks, long content to play it safe and lurk in the shadows, began experimenting, innovating, and proving they can move differently yet fast.

                      As the year wraps up, we zoom in on the standout trends across publicly traded companies I covered this year — and what they signal for 2026.

                      Trend 1: AI — How AI found its place in banking, from a back-office helper to a decision-making partner

                      2025 began with a mix of fascination and unease around AI in the financial sector. There was a cloud of uncertainty: could AI take over jobs, reshape banking as we know it, or disrupt entire business models? At industry gatherings like the World Economic Forum 2025 at Davos, AI wasn’t just a topic – it was the topic. Panel after panel debated whether AI would be a villain, a tool, or a teammate.
