Compliance departments run a quiet metric: how often a new term shows up in official filings before the institution has a policy for it. By that measure, stablecoins crossed a line in 2025. Mentions of stablecoins in SEC filings rose 64 percent in the months after federal legislation passed in July, according to the State of Crypto 2025 report from a16z crypto, and the banks, insurers, and asset managers doing the mentioning were not describing a curiosity. They were describing a competitor, a customer request, and in several cases a product roadmap. That is why financial institutions are paying closer attention to stablecoins: dollar tokens now move real volume through markets those institutions considered their own.
From dismissal to due diligence
The institutional posture toward stablecoins has moved through three phases. In the first, roughly 2019 through 2022, dollar tokens were treated as plumbing for crypto exchanges, relevant to bank risk teams only when a client touched an exchange. The collapse of several crypto firms in 2022 hardened that distance. Most institutions concluded the sensible policy was no policy at all.
The second phase arrived when the usage data stopped fitting the trading story. Chainalysis reported in its Stablecoins 101 research that stablecoins came to represent more than two thirds of the trillions of dollars in cryptocurrency transaction volume recorded in recent months, and that growth in transfers was strongest in regions where the use case was payments and savings rather than speculation. An instrument doing that work looks less like a casino chip and more like a deposit substitute.
The third phase is legal. The GENIUS Act, passed in July 2025, gave the United States its first federal law dedicated to stablecoin issuance, with reserve and disclosure requirements that let a regulated institution engage without inventing its own rulebook. Circle’s public listing in the same year put an issuer’s financials on display with audited disclosures. Due diligence became possible, so due diligence began.
The numbers that changed the conversation
Scale is the first thing a bank strategy team checks, and the scale is no longer dismissible. Stablecoins processed $46 trillion in total transaction volume over the past year, up 106 percent from the year before, per a16z crypto. Filtered for bots and other artificial activity, the adjusted figure is $9 trillion, up 87 percent, which places tokenized dollars in the same conversation as major card networks.
The stock matters as much as the flow. Total stablecoin supply now exceeds $300 billion, with Tether and USDC accounting for 87 percent of it and more than 99 percent of all stablecoins denominated in US dollars, according to a16z crypto. Monthly adjusted transaction volume reached roughly $1.25 trillion in September 2025. For comparison, that supply figure already exceeds the deposits of most mid-sized American banks by an order of magnitude.
The pattern of the growth matters to analysts as much as its size. Stablecoin transaction activity has become largely uncorrelated with crypto trading volume, per a16z crypto, which is the statistical signature of payments rather than speculation. A flow that persists through crypto drawdowns cannot be filed under market froth. Institutional research teams noticed the decoupling before most product teams did, and it changed the internal classification of the asset from trading exposure to payments competition.
Growth of that shape forces a classification question. A product with a fixed dollar value, instant transfer, and hundreds of billions in balances is functionally close to a checking account without the bank. Institutions that classify it honestly end up studying it, which is precisely what the filing mentions suggest they are doing.
Why institutions are paying closer attention to stablecoins
The first reason is deposit competition. Every dollar that sits in a stablecoin wallet is a dollar that is not sitting in a transaction account, and payment balances are among the cheapest funding a bank has. The threat is still small relative to the US deposit base, but it is growing at a pace no internal product line matches, and it is concentrated in exactly the cross-border and corporate niches where fees are richest.
The second reason is client demand. Corporate treasurers have discovered that a dollar token settles in less than one second for less than one cent, almost anywhere in the world, per a16z crypto, and they have started asking their banks why a Friday afternoon wire cannot do the same. Institutions that ignore the question watch the flow migrate to fintechs built on top of banking-as-a-service APIs, which can wrap token settlement in a familiar interface.
The third reason is strategic positioning. The infrastructure connecting tokens to accounts is being built now, and the institutions that build it will set its terms. TechBullion has tracked how quickly adjacent plumbing matured in its reporting on digital transformation in American finance. Settlement rails tend to be winner-take-most markets. Sitting out the build phase means renting someone else’s rail later.
The Treasury market connection
Stablecoins also matter to institutions as a fixed income phenomenon. A Bank for International Settlements working paper found that stablecoin issuers held more than $270 billion in assets under management as of December 2025, surpassing the short-term US securities holdings of major foreign investors. During 2025 the issuers purchased nearly $35 billion in US Treasury bills, a pace the BIS compares to the largest US government money market funds.
The same paper measures the market footprint. Inflows into stablecoins compress three-month Treasury bill yields by about 4 basis points within ten days, with the effect deepening to roughly 5 basis points before fading. The impact concentrates at the short end of the curve and gets stronger during periods of Treasury market stress. Any institution running a money market desk now has a new flow variable to model.
That footprint cuts both ways. A growing, price-insensitive buyer of bills is helpful to a government issuing heavily. A holder that could face redemption waves is a transmission channel for stress. The BIS frames stablecoins as a monetary policy and financial stability question, not merely a payments one, and bank treasurers read the same papers central bankers do.
The customer flows behind the strategy decks
Institutional interest tracks customer geography, and the geography is specific. Chainalysis found that Latin America and Sub-Saharan Africa are the fastest growing regions for retail and professional stablecoin transfers, each expanding more than 40 percent year over year, with Eastern Asia at 32 percent and Eastern Europe at 29 percent. Those are the same corridors where correspondent banking is most expensive and where global banks earn their richest cross-border margins.
The remittance math explains the pull. Sending a $200 remittance from Sub-Saharan Africa costs about 60 percent less using stablecoins than through traditional fiat channels, according to Chainalysis. A cost gap that wide does not stay unexploited. Money transfer operators, payroll providers, and trade finance desks all sit on flows that reprice the moment a customer discovers the cheaper rail.
For banks serving emerging markets, the defensive logic is stronger still. Customers in weak-currency economies use dollar tokens to protect purchasing power, per Chainalysis, which means the deposit outflow happens whether or not the local bank participates. Institutions in those markets face a choice between distributing tokenized dollars themselves or watching balances migrate to offshore wallets, and several are concluding that distribution is the safer seat.
What banks are actually building
The response has moved from memos to products. Citigroup, Fidelity, and JPMorgan have all announced stablecoin or tokenized cash initiatives, per a16z crypto, and payment companies moved even earlier, with Stripe acquiring the stablecoin infrastructure firm Bridge to own settlement rails outright. The pattern is consistent: regulated institutions want the deposit-like balances and the settlement revenue inside their own perimeter.
Distribution strategies differ by institution type. Universal banks are building tokenized deposit systems for corporate clients, where the compliance perimeter is easiest to control. Custodians are extending existing asset servicing to reserves. Retail-facing firms are watching how neobanks expand through embedded finance partnerships, since the same partnership logic applies to wallet features. Wall Street’s growing comfort with public networks, visible in Ethereum sentiment improving on institutional expansion, lowers the reputational cost of shipping.
The build-versus-partner decision usually lands on partnership first. Issuing a token requires reserves, redemption operations, and a licensing path. Integrating one requires an API and a risk framework. Most institutions will start by holding, moving, and servicing existing tokens, and only a handful will issue their own.

The risks compliance teams flag
Attention is not endorsement, and the internal memos list real hazards. Concentration leads the list. Two issuers control 87 percent of supply, so a reserve problem at either would be a category-wide event, not a single-name one. Reserve transparency has improved under the GENIUS Act’s disclosure rules, but disclosure standards are newer than the balances they cover.
Financial crime exposure is the second entry. Chainalysis estimates that less than 1 percent of on-chain transaction volume is illicit, yet stablecoins have appeared in laundering, fraud, and sanctions evasion cases, and banks carry the compliance burden when tokenized flows touch their accounts. The mitigating factor is technical: centralized issuers can freeze tokens in specific wallets, per Chainalysis, a control traditional cash never offered.
The third entry is run dynamics. A token redeemable on demand against a portfolio of bills behaves like a money market fund in stress, and the BIS finding that flows move bill yields within days shows the transmission channel is already live. Institutions remember 2008 well enough to model what happens when a cash-like instrument breaks its promise.
The regulatory map institutions now navigate
Regulation is what converted curiosity into permitted activity. In the United States, the GENIUS Act set federal rules for issuance while the House passed the CLARITY Act on broader market structure, per a16z crypto. The combination gives compliance officers something they can cite in an approval memo, which is the practical unit of institutional progress.
Other jurisdictions supply the comparison set. The European Union’s MiCA framework brought stablecoins under a unified regime, and markets such as Singapore and Japan have issued their own guidelines, according to Chainalysis. For a global bank, the emerging picture is workable: the major markets are converging on reserve quality, redemption rights, and disclosure as the core tests.
The open question is supervision of the seams. A token issued in one jurisdiction, held in a second, and redeemed in a third crosses supervisory borders faster than the supervisors share information. Institutions that operate in all three jurisdictions may end up as the de facto integration layer, which is a business opportunity dressed as a compliance problem.
What it means for fintech founders and partners
For founders, institutional attention changes the buyer. Products that made sense as consumer wallets now have a second market as bank infrastructure: reserve reporting tools, wallet screening, redemption management, and treasury dashboards all map to line items in an institutional budget. Selling picks and shovels to regulated miners is slower than launching a token, but the contracts renew.
For banks evaluating partners, the diligence template already exists. The questions asked of any fintech vendor, uptime, data handling, regulatory posture, apply directly, with reserve mechanics added. Institutions that already learned to integrate outside technology through API partnerships will move fastest, because the organizational muscle transfers even when the asset class is new.
Timing is the strategic variable. Moving early means building against rules that may still shift. Waiting means conceding the corporate settlement niche to whoever moved first. Most institutions are resolving that tension with small, revocable commitments: a custody pilot here, a tokenized deposit trial there, each one designed to be expanded if the volume arrives.
The last time banks watched a cash-like instrument grow this quickly outside their walls, it was the money market fund in the late 1970s, and the eventual answer was absorption rather than resistance. Stablecoins are tracing the same arc with better technology and a federal statute already in place. The institutions reading the filings most closely are not asking whether tokenized dollars will matter to their business. They are deciding which quarter to put the answer in production.
