For most of the last decade, the promise of digital assets was rebuilding financial infrastructure, redefining how money and assets move globally. However, the reality was about price. Bitcoin's swings, Ethereum's roadmap, memcoins. The denominator was always speculation. But underneath the noise, something more durable was being assembled. Stablecoins, digital representations of a currency, often the U.S. Dollar, have crossed a threshold over the last 12 months. They have shifted from a crypto trading instrument to the connective tissue of global commerce.
Since 2021, stablecoin transaction volume has decoupled from crypto market cycles in dramatic fashion. Through the 2022 bear market, asset prices cratered while stablecoin usage accelerated. The divergence means the use cases driving growth are structural.
The Problem That Was Always There
The global payments infrastructure is a $2 trillion-a-year industry built on a foundation of correspondent banking relationships established in the 1970s. When a company in Houston wires funds to a manufacturer in Vietnam, that payment enters a relay system of intermediary banks, each adding fees, compliance layers, and latency. Three to five business days. Visibility gaps. Capital that is simply in motion, doing nothing, but costing something.
This is not a technology problem that went unsolved because it was hard, but instead because the incumbents who controlled the rails had no incentive to rebuild them. SWIFT processes roughly $5 trillion in messages daily – the system works, in the sense that the water reaches the tap, even if the pipes are a century old. Delays in settlement made it easier to manage risk, mostly with manual reviews, and the slower funds moved, the more money banks in the middle made.
By representing the dollar as a token on an open, programmable network, they collapse a multi-day settlement process into a transaction that takes seconds. The payment and its value move as one. No silos, no correspondent fees, no weekend delays. For the first time, money can move at the speed of information.
B2B payment flows now constitute the majority of stablecoin payment transaction volume – businesses paying suppliers, settling invoices, managing treasury across borders, not retail traders cycling between assets. That shift in composition is the most important story in fintech right now, and is setting the stage for a massive shift in global payment infrastructure.
Yield Meets Liquidity
Within B2B payments, corporate treasury has always faced a fundamental tradeoff: liquidity or yield. Money parked in an operating account is accessible but earns almost nothing. Money earning real returns in short-term Treasuries is locked up, requiring manual intervention to deploy. At most major banks, a business checking account yields around 1.5% and comes with constraints on how often funds can move. On top of this, enterprises transacting globally need to hold days worth of funds across accounts to manage settlement delays.
Top-tier stablecoins are starting to restructure this entirely. Because they are backed 1:1 by short-term U.S. Treasuries, the token itself becomes the yield-bearing instrument (depending on the jurisdiction). There is no separation between the money you earn on and the money you spend. A corporate treasurer can hold operating capital in a single account, earn yield continuously, and send a payment to a supplier in a different country at 2 AM on a Sunday – from the same balance, instantly. While this capability varies by jurisdiction and regulatory frameworks, the infrastructure is being built to instantly swap stablecoins for tokenized treasuries, or other tokenized investment assets, which opens up this new era of treasury optimization.
Outside the U.S., where access to dollar-denominated savings vehicles is limited, the differential is even bolder. Stablecoin accounts are already offering 3.6% or higher, multiples above what local banks provide, while maintaining the liquidity of a checking account. For CFOs managing global operations, this is a rethinking of how working capital functions.
The Last Mile Is the Whole Game
The most persistent challenge is the last mile: converting digital dollars into local currency for recipients in Lagos, Manila, or Mexico City. A stablecoin balance is only as useful as the infrastructure that can convert it into naira or pesos at the point of need, instantly and at low cost.
At Oak, we believe that the real value is being created at the infrastructure aggregation layer. Here, a new generation of providers are building the plumbing that connects directly to local payment networks, liquidity hubs, FX markets, and compliance frameworks into a single seamless flow.
To the sender in New York, it looks like a simple payment transfer. In the background, a platform is routing through the most efficient chain of assets, finding the best price across global FX liquidity hubs or connecting to a local counterparty that wants a specific stablecoin and holds local fiat, completing the full transaction lifecycle end-to-end. The business model is not a patchwork of local licenses bolted together over years, but a compliant bridge at the entry and exit points of an otherwise borderless network.
The companies building this layer well are the ones most likely to define the next decade of cross-border finance, serving as the aggregators who make complexity disappear for developers and enterprises.
Programmable Money and the Agentic Economy
The most forward-looking dimension of this shift coming into view is agentic money movement.
AI agents are beginning to take on autonomous economic roles, including managing workflows, procuring services, and settling microtransactions on behalf of enterprises. The challenge is that a software agent cannot open a bank account. It cannot navigate a compliance queue or wait three days for settlement. It needs a payment rail that is natively digital, always available, and programmable.
Stablecoins are that rail. Stablecoin smart contracts and some of the new blockchains being built around stablecoins, allow for the rules of a transaction to be embedded in the transaction itself. An agent can execute micropayments at fractions of a cent to a data provider per API call, or move treasury funds with automated logic. It can enforce conditional logic, releasing funds only when a cryptographically signed delivery event occurs. It can self-regulate spending within hard-coded parameters, operating without human authorization under defined thresholds.
Policy embedded in a payment is a new concept. For enterprises deploying AI agents at scale, it means financial controls that are auditable, automatic, and tamper-resistant. The implications for procurement, logistics, and supply chains are significant and still largely unpriced.
The Regulatory Moment
The path to institutional adoption runs through regulatory clarity. In the United States, proposed legislation like the GENIUS Act and Clarity Act has attracted attention, in part because some of its provisions reflect the lobbying interests of traditional banks who see stablecoins as an existential threat to the deposit model. If a consumer can hold a liquid, dollar-denominated account earning 3.6% as easily as a checking account, the spread that funds traditional banking begins to compress. However, as stablecoins have made global money movement infrastructure global by default, every regulatory jurisdiction now faces its own competitive pressure on innovation.
The broader federal trend is constructive. OCC banking and trust charter frameworks are providing a pathway that serious stablecoin issuers can build toward. Major institutions are not making exploratory bets here. PayPal has launched its own stablecoin with Paxos, Stripe acquired Bridge, and other large payment infrastructure providers like Rapyd and Highnote are integrating stablecoin settlement into their core payment infrastructure.
These trends are also promoting innovation with newer companies like Catena Labs building a regulated financial stack for agentic money movement or emerging FX infrastructure players like XFX, building modern infrastructure to merge fiat and stablecoin FX markets.
The compliance, risk and payment operations layer itself is becoming a massive opportunity. Solving identity, fraud verification and reconciliation on and off chain as money moves faster is a prerequisite for institutional participation at scale. The companies that crack it will unlock a significantly larger addressable market than what exists today.
Where We Are
The last decade of digital assets was, in retrospect, a proof-of-concept phase. The technology and required infrastructure got built. Custody and transaction efficiency got figured out. The on and off-ramps were constructed. Now the question is whether the infrastructure delivers genuine economic utility. We believe that, increasingly, the answer is yes, in ways that are measurable, repeatable, and scaling.
Stablecoins are not a crypto story. They are a story about the efficiency of moving value across a global economy that has never had a truly interoperable financial layer. The fundamental properties – instant settlement, transparent backing, programmability, 24/7 availability – are not speculative features. They are working in production today, for businesses that get tangible value from the outcomes it delivers.
The last mile remains hard. Regulatory arbitrage remains a risk. Building trust with the enterprises that matter takes time. Stablecoins have penetrated only 0.01% of global money movement. As these points of friction get solved the direction of motion and the size of the opportunity is clear. The companies that win this market will be defined by their ability to make the complexity disappear, and to deliver, for the first time, a financial system that works as fast as the businesses depending on it.
