The Future of Money: Understanding Payment Systems in a Digital Age

The Weight of History on Modern Banking

The way we handle money today isn’t just a product of modern innovation—it’s deeply rooted in decisions made centuries ago. Dan Awrey, a law professor at Cornell and author of “Beyond Banks: Technology, Regulation, and the Future of Money,” explains that we’ve essentially “put all our eggs in one basket” when it comes to payment systems. This wasn’t necessarily a bad choice at the time, but it’s created significant challenges as technology has evolved. Think of it like building a city around horse-drawn carriages and then trying to retrofit it for cars and highways. The basic infrastructure was designed for a completely different world, and now we’re feeling the strain. These historical decisions created what economists call “path dependency”—essentially, we’re stuck on a particular road because of choices made long ago, and switching lanes becomes increasingly difficult as time goes on. Understanding this history isn’t just academic curiosity; it’s essential for figuring out how to move forward. The banking frameworks established in previous centuries continue to shape how money moves through our economy today, even as consumer expectations and technological capabilities have transformed dramatically. This creates tension between what’s possible with modern technology and what’s practical within our existing systems. The challenge facing policymakers and financial institutions isn’t just about adopting new technology—it’s about managing the transition from systems built for a completely different era.

What Actually Makes Money “Good”?

When most people think about what makes money valuable, they imagine it’s all the same question—but Awrey points out a crucial distinction that often gets overlooked. Good money and good payments are actually two different things, defined by different criteria. Good money, at its core, is defined by law and institutions. It’s about the legal framework that gives currency its value and stability, the government backing that ensures a dollar today will be recognized as a dollar tomorrow. This is the realm of central banks, treasury departments, and legal systems. On the other hand, good payments are defined by technology and the governance frameworks around that technology. This is about how quickly money can move, how securely it can be transferred, how easily people can access it, and how smoothly different systems can talk to each other. A society could theoretically have good money but terrible payment systems, or vice versa. Understanding this distinction is foundational for anyone thinking about financial systems. Policymakers and economists need to recognize that improving one doesn’t automatically improve the other. You can’t just throw better technology at a legal framework problem, and you can’t regulate your way to faster payment processing. The governance frameworks that enable good payment technology need to be developed thoughtfully, considering user experience, security, accessibility, and interoperability. This distinction becomes especially important as we navigate the shift toward digital currencies and new payment technologies, where the lines between money itself and the systems for moving it can become blurred.

The Limits of Central Banking Power

Central banks hold tremendous power in our financial systems, but Awrey raises an important question about the limits of that authority. Just because central banks can do something doesn’t necessarily mean they should, especially when it comes to acting as central planners in response to technological changes and shifting consumer preferences. As Awrey puts it, “If central bankers want to be central planners then that’s something that’s up for societal debate but it’s not something that we currently give them the ability to do outside of the payment system.” This is a crucial point in an era where central bank digital currencies are being seriously discussed. Central banks are designed to manage monetary policy—controlling inflation, maintaining employment, ensuring financial stability. They’re not necessarily designed to make decisions about which payment technologies consumers should use or how the retail payment market should be structured. These are fundamentally different questions that require different types of expertise and democratic input. The challenge is that technological advancement doesn’t wait for regulatory clarity, and consumer behavior is already shifting rapidly toward digital payments. Central banks face a difficult balancing act: they need to ensure financial stability and protect consumers, but they also need to avoid stifling innovation or making choices that should properly be left to markets and democratic processes. The financial system requires adaptability, and rigid central planning could actually undermine the innovation that consumers are demanding. This raises broader questions about governance in the digital age—who gets to decide how money works, and through what processes should those decisions be made?

A Cart With No Apples: The Legacy System Under Pressure

The traditional banking system is facing a crisis of relevance, and the longer policymakers delay in addressing it, the worse the situation becomes. Awrey uses a vivid metaphor: “The longer policymakers spend thinking well why upset the apple cart the more they’re gonna find that there’s no apples left in the cart and they’re left to clean up a mess instead of building a new and better cart.” Consumer preferences have already shifted dramatically toward digital payments. People want instant transfers, seamless international payments, integration with their digital lives, and lower fees. The legacy banking system, built on infrastructure from another era, struggles to deliver these features. Meanwhile, new players—fintech companies, tech giants, cryptocurrency platforms—are stepping in to meet consumer demand. The result is a fragmentation of the payment system and a gradual erosion of traditional banking’s central role. Policymakers face a genuine dilemma here. On one hand, the existing system represents enormous investment, provides important stability, and connects to deep regulatory frameworks designed to protect consumers and ensure financial stability. Disrupting it carries real risks. On the other hand, trying to preserve a system that no longer meets consumer needs is ultimately futile and potentially more dangerous. The financial system doesn’t exist in a vacuum—it exists to serve the economy and the people within it. If it’s not doing that effectively, change is inevitable, whether planned or chaotic. The smarter approach is to actively design and build new systems that preserve the valuable aspects of the legacy system while embracing the capabilities of modern technology. This requires policymakers to shift from a defensive posture—protecting what exists—to a constructive one—building what should exist.

The Two Faces of Money: Short-Term Flow and Long-Term Stability

Money serves different functions depending on your time horizon, and this creates some interesting tensions in how we should think about monetary innovation. In the short term—day to day, week to week—what matters most about money is its payment qualities. Can you use it easily? Does it transfer quickly? Is it accepted where you need to spend it? This is where technology shines and where many innovations are focused. But zoom out to the long term, and different features become critical. Over months, years, and decades, what matters is whether money maintains a stable nominal value, especially during times of stress. Will the money you saved today be worth roughly the same amount when you need it later? Can you count on it during economic turbulence? This is where legal frameworks, institutional backing, and conservative asset management become crucial. This dual nature of money creates challenges for new monetary proposals. Something might work brilliantly as a payment system but fail as a store of value, or vice versa. Consider equity-based money proposals, where the value of your money fluctuates with market performance. For someone with substantial wealth who can absorb volatility, this might be acceptable or even attractive—you get payment convenience with potential upside. But as Awrey notes, “It’s not that this proposal doesn’t work it just doesn’t work for a certain subset of the population namely the population living from paycheck to paycheck.” If your money might be worth 15% less when rent is due because the market had a bad week, that’s not a functional payment system for your life, even if it works fine for wealthier individuals. Any serious monetary innovation needs to grapple with both timeframes and serve people across different economic circumstances. The challenge is that the features that optimize for short-term payment efficiency sometimes work against long-term stability, and vice versa.

Bankruptcy: The Kryptonite of New Payment Systems

One of the most significant threats to innovative payment systems and digital currencies isn’t hacking or technological failure—it’s the boring old legal process of bankruptcy. Awrey identifies this as a fundamental vulnerability: “Almost all of them do for the same reason which is that they’re subject to conventional bankruptcy processes… bankruptcy as the kryptonite for credit based money you can’t use the money when you wanna use it and when you get some of that money back it’s very likely gonna be the case that it is not the same nominal value as it was when you put it in.” This might seem abstract until you consider what it means in practice. If a stablecoin issuer or payment platform goes bankrupt, your “money” held in that system becomes locked up in legal proceedings. You can’t access it when you need it, and when you eventually get something back, it might be fifty cents on the dollar or less. This completely undermines the fundamental requirement that money maintain a stable nominal value. The bankruptcy threat is directly related to asset volatility—the riskier the assets held by the issuer, the higher the chance of bankruptcy. This is why asset management becomes absolutely critical for digital currency stability. Traditional banks hold relatively conservative assets and are subject to extensive regulation precisely to minimize bankruptcy risk. Many new payment systems and digital currencies, in their quest for efficiency and returns, take on more risk. Furthermore, current regulatory frameworks for “skinny master accounts” at the Federal Reserve—which could potentially provide a safer foundation for new payment systems—are limited by existing legislation. Section thirteen one of the Federal Reserve Act constrains who can access these accounts and under what terms. Without legislative change, this limits the options for creating truly bankruptcy-remote digital payment systems. The financial system must somehow balance innovation and accessibility with the fundamental requirement that people’s money remains available and stable in value. Solving the bankruptcy vulnerability isn’t just a technical or financial challenge—it’s a legal and regulatory one that requires thoughtful policy development and possibly new legislative frameworks. The future of money depends on finding solutions that deliver modern payment capabilities while maintaining the stability and reliability that make money functional in the first place.
