Stablecoin Compliance for MSBs
Stablecoins represent a specific subset of virtual currency that raises distinct regulatory questions. While most virtual currency compliance discussions focus on Bitcoin and other volatile digital assets, stablecoins occupy an unusual position: they're virtual currencies, but they're designed to maintain a stable value relative to something else—usually the US dollar. This stability changes everything about how they're regulated and how MSBs must approach compliance with them.
The regulatory question always starts with what a stablecoin is. From a technical perspective, a stablecoin is a token on a blockchain that maintains a relatively stable value through mechanisms like collateralization, algorithmic rebalancing, or a commitment by an issuer to redeem the token at a stated price. From a regulatory perspective, what matters is what the stablecoin is used for and how it's structured.
FinCEN's guidance applies different rules depending on whether you're issuing a stablecoin or transmitting it. If you're an issuer—meaning you create the stablecoin and put it into circulation—you're engaged in a different activity than if you're a transmitter who accepts stablecoins from customers and pays them out to other customers. FinCEN has indicated that stablecoin issuers may be money transmitters themselves, particularly if they allow customers to convert fiat currency into the stablecoin and back. But the nature of the obligation differs from a traditional transmission business.
Let me ground this in a concrete scenario. In 2021, I advised a financial technology company that wanted to launch a USD-backed stablecoin. The team had already raised venture capital and had engineering talent. What they didn't have was clarity on the regulatory requirements. We mapped out the compliance framework across multiple dimensions.
First, the issuance itself. The company would create tokens backed one-to-one by US dollars held in reserve. Customers would send the company dollars, receive tokens, and could later send tokens back and receive dollars. This is money transmission in the classic sense—the company is accepting money for transmission and paying it out. FinCEN treats stablecoin issuers this way. So the company needed to register with FinCEN as a money transmitter.
Second, state licensing. We determined that the company needed money transmitter licenses in virtually every state because it was accepting fiat currency and transmitting the value of that currency in the form of stablecoin tokens. The analysis was the same in every state: you're receiving funds from customers and paying out value to other parties. That's money transmission regardless of whether the value is transmitted as dollars, checks, or stablecoin tokens.
Third, reserve requirements. This is where stablecoin issuance becomes more complex than traditional money transmission. States increasingly expect stablecoin issuers to hold actual reserves backing the stablecoins in circulation. Some states have begun requiring that these reserves be held with state-licensed banks or trust companies. Some require regular audits of the reserves. Some require that reserves exceed the value of stablecoins outstanding—essentially a capital requirement on top of the net worth requirements already imposed on money transmitters.
A practical example makes this clear. If a stablecoin issuer has one million tokens outstanding and each token is backed by one dollar, the issuer needs to have one million dollars in reserve. But many states go further and require that the issuer also maintain additional capital to cover operating losses, fraud, system failures, or other contingencies. This transforms the business model. If you need to maintain a two-to-one reserve ratio plus net worth requirements of $500,000 or $1 million, the minimum capital needed to launch a stablecoin business becomes substantial.
Some states have specifically addressed stablecoin reserves. Texas, for instance, clarified in guidance that stablecoin issuers must maintain reserves equal to the outstanding value of the stablecoins. New York's BitLicense requirements include extensive reserve and margin rules. Wyoming's new stablecoin chartering framework requires specific reserve structures. These aren't casual requirements—they're central to the regulatory framework.
The auditing requirement compounds this. If you're issuing stablecoins and the state requires reserves, the state often also requires independent audits proving that the reserves actually exist. This means hiring a certified public accountant or audit firm to regularly verify your reserve holdings. The cost isn't trivial, and the audit requirements can be very specific. Some states want monthly audits. Some want quarterly. Some want annual audits plus periodic spot checks. The auditor needs access to your banking records, your reserve accounts, your reconciliation processes.
From an operations perspective, I've seen this create a straightforward but expensive requirement: stablecoin issuers end up maintaining accounts at banks or trust companies that allow the auditors to directly verify reserve holdings. This often means using institutional banking relationships rather than standard business accounts. It also means accepting that your banking relationship is part of the regulatory structure itself—the bank is the custodian of the reserves that back your stablecoins.
Now, how does stablecoin transmission work differently from issuance? If you're not issuing a stablecoin but instead facilitating exchanges of stablecoins between customers, you're a transmitter of that stablecoin, and you face traditional money transmitter licensing requirements. But you don't necessarily face the same reserve and auditing requirements as an issuer, because the stablecoin itself is backed by the issuer's reserves. You're just facilitating transmission.
However, if you take custody of stablecoins on behalf of customers, FinCEN's guidance suggests you may be a money transmitter even if you're not issuing the stablecoin. This is the custody question: if a customer gives you stablecoins and you hold them on the customer's behalf, you're likely a money transmitter. The line becomes fuzzier if you're a non-custodial exchange where customers never give you control of their assets—they just use your platform to find counterparties and execute trades.
The intersection of securities law and stablecoin regulation adds another layer. Some stablecoin projects have structured themselves as something between a currency and an investment. For instance, a stablecoin that pays interest to holders or includes governance rights to token holders may trigger securities law. The SEC has increasingly looked at stablecoins that have investment characteristics and treated them as securities. This can make the licensing problem exponentially more complex because now you're not just a money transmitter—you're also potentially a broker-dealer or investment adviser.
State-specific stablecoin rules have begun to emerge. New York's approach is to treat stablecoins as virtual currency and apply the BitLicense framework. Wyoming's approach is to create a specialized stablecoin charter that gives issuers a path to operate without necessarily becoming money transmitters, provided they meet specific requirements around reserves and governance. Texas, Florida, and other states have treated stablecoins as falling within existing money transmitter definitions.
Building a compliant stablecoin operation means addressing several components in parallel. You need to determine your licensing requirements across all relevant states. You need to establish reserve arrangements with banking partners who understand the stablecoin business. You need to set up your auditing process and select your auditor. You need to build out your compliance program with AML/KYC requirements, transaction monitoring, and customer due diligence. You need to address banking relationships, which are often challenging because banks remain cautious about cryptocurrency and stablecoin-related activities.
One team I worked with spent eighteen months launching a stablecoin operation. The first six months were spent mapping the regulatory landscape and obtaining necessary licenses. The next four months were spent setting up banking relationships and reserve arrangements. The following three months were devoted to building the compliance program and implementing transaction monitoring. The final three months were testing and validation before launch. The total cost, including legal, compliance, auditing, and banking setup, exceeded $2 million.
The business economics of stablecoins make this investment challenging. Many stablecoin platforms operate on razor-thin margins. If you're taking deposits, issuing stablecoins, and allowing redemptions, you're not generating revenue from the stablecoin issuance itself—you're generating revenue only from fees on deposits, redemptions, or transactions. Some stablecoin platforms have attempted to generate returns on reserves by investing them or lending them out, but this introduces risk and complexity that regulators scrutinize heavily.
The question of what happens with reserve assets creates a secondary compliance issue. If your stablecoins are backed by reserves earning returns, are you conducting securities activities? Are you a registered investment adviser? Some states have specific rules about what you can do with reserves. If you're required to keep them in a non-interest-bearing account, that's one thing. If you can deploy them, that creates new questions.
The future of stablecoin regulation is still in flux. Congress has held hearings on stablecoin regulation. The Federal Reserve and Treasury Department have issued statements indicating that stablecoins should be regulated like bank deposits or demand accounts. The current trajectory suggests that stablecoin regulation will become more stringent, with higher reserve requirements, more extensive auditing, and potentially a federal framework overlaying state requirements.
Recent enforcement actions have also signaled how regulators view stablecoin compliance. When regulatory agencies have taken action against stablecoin issuers or platforms, the complaints have focused on inadequate reserves, failure to conduct AML/KYC, fraud, inadequate disclosures, and operating without required licenses. These enforcement actions confirm that the basic requirements—licensing, reserves, auditing, AML/KYC—are not optional.
For MSBs considering stablecoin operations, the practical reality is straightforward: you can do it, but you need to commit serious resources to compliance and be prepared to operate on thin margins while maintaining robust operational infrastructure. The licensing is achievable. The auditing is achievable. The banking is harder but possible. The profitability is the real question.
Practitioner's Bottom Line: Stablecoin compliance requires addressing issuance versus transmission distinctions, maintaining reserves audited by independent third parties, obtaining money transmitter licenses in relevant states, and building robust AML/KYC programs. The regulatory framework is becoming more stringent across states, with higher reserve requirements and more frequent auditing expectations. A stablecoin operation is achievable but expensive—plan for minimum capital of $1-5 million depending on your state footprint and assume 12-24 months to full operational launch including licensing, banking setup, and compliance implementation.
