Stablecoins are moving from crypto curiosity to a practical finance tool. Here's an operator-level look at what they are, where they save real money today, and what to ask before bringing them into your stack.
This piece is adapted from an Operators Guild Focus Session on stablecoins for finance teams, led by Garrett from Altitude, and shaped by a live discussion among operators who are actively moving money across borders, paying global teams, and managing treasury inside real companies. Focus Sessions are small-group, member-only conversations where operators compare notes on decisions in flight, pressure-test tradeoffs, and surface the operational realities that rarely show up in vendor decks or category overviews.

Stablecoins have spent most of the last decade filed under crypto, somewhere between speculative and irrelevant for most finance teams. That filing is now out of date. The stablecoin market has grown from around $5 billion in circulation in 2020 to roughly $315 billion today, moving more than $10 trillion in annual payment volume. Stripe and Mastercard have each made billion-dollar acquisitions in the space, Visa is settling billions a year, and Circle, the issuer behind USDC, is a public company.
For an operator, the takeaway is simple. This will come across your desk. The useful goal is to be able to talk about stablecoins clearly and to know the handful of places where they genuinely save time and money.
Start with what a stablecoin actually is
A stablecoin is a digital dollar. Each one is backed one-to-one by a reserve of cash and short-term US Treasuries. Deposit a dollar with an issuer, that dollar goes into the reserve, and you receive one stablecoin in return. You can redeem it for a dollar at any time, which is what keeps it stable. The $315 billion in circulation maps to roughly $315 billion sitting in reserves.
It helps to separate stablecoins from crypto assets like Bitcoin. Bitcoin is an investment asset whose price floats with the market and whose supply is capped at an arbitrary number. A stablecoin like USDC is engineered to hold at one dollar, because real dollars and Treasuries sit behind every coin. Both happen to run on the same blockchain rails, and they represent very different things. One analogy from the session: a gold ETF and an S&P 500 ETF trade through the same plumbing while holding completely different assets.
Think of it as another payment rail
The most practical way to hold stablecoins in your head is as a payment rail, sitting alongside ACH, wire, SEPA, and SWIFT. When you log into your bank to move money, you pick one of those options. A stablecoin is one more option, with a different cost and speed profile.
A traditional wire often costs $10 to $15 and can take up to three days. A stablecoin transfer settles in seconds, runs 24-7, and costs less than a cent, often sponsored by the platform you are using. The dollar itself stays the same. The network it travels on is what changes how far and how fast it can move.
The session framed the progression this way: money started as cash, became a digitized balance sitting in a local bank, then became instantly sendable inside private networks like Venmo. Stablecoins extend that same path onto a global, open network that anyone can access and build on.
Know which stablecoin you are holding, and why
Stablecoin is a category, and the options inside it are not interchangeable. Two dominate today: USDT, with around $186 billion in circulation and heavy adoption in emerging markets and on exchanges, and USDC, which has become the default for many US companies and fintechs, with names like Shopify, Stripe, and BlackRock leaning toward it.
When you evaluate a stablecoin, a few things matter:
- The reserves, and what actually backs each coin
- Transparency, including how often the issuer reports and attests to that backing
- Regulation and compliance
- On-chain liquidity
USDC is issued by Circle, a publicly traded company that publishes weekly reserve disclosures and monthly third-party attestations, and it operates under the GENIUS Act, the US law that gives stablecoin issuers a regulatory roadmap. The main risk to understand is issuer risk, the question of whether the reserves are truly there. A fully backed stablecoin holds a dollar in reserve for every dollar issued, so the funds are not lent out the way bank deposits are under a fractional reserve model.
Where stablecoins create real value today
The value shows up in specific places, mostly in global and fragmented financial operations. Much of it runs through stablecoin payment service providers, or PSPs. These sit in the middle, accept a stablecoin like USDC, convert it into local currency, and deliver it into a local bank account. They connect a stablecoin balance to local banking systems around the world, which is what makes cross-border payouts fast and cheap. Three use cases came up as the ones CFOs are running today.
Cross-border payments. Take a $1 million payment from a US company to an EU vendor. Over SWIFT, you might absorb a roughly 1% FX markup you cannot always see in advance, around $30 in intermediary fees as the payment hops through correspondent banks, and a three to five day wait with little visibility along the way. All in, that can run close to $10,000. Routed through stablecoins, the same payment follows what people call the stablecoin sandwich: dollars convert to a stablecoin, move in seconds, and pay out in local currency on the other side through a rail like SEPA. Fees are transparent, settlement is near-instant, and the savings can reach $7,000 on that single payment.
Intercompany treasury. Companies with multiple entities and accounts across countries traditionally have to open banking relationships in each market, pre-fund every account, eat fees on each transfer, and untangle reconciliation at month end. Reconciliation is the complaint operators raise most. With stablecoins, that collapses into one global account, instant transfers between entities, no transfer fees, and far simpler reporting.
Paying global teams and contractors. Monthly pay runs often span 25 to 100 payments, sometimes more, across many countries and rails. Pairing stablecoins with PSPs lets a finance team run the whole batch from one platform. A single pay run might cover 50 recipients across 15 countries and five payment rails, without juggling five separate logins.
There is a related benefit worth naming: access to dollars. Around 90% of stablecoins in circulation are denominated in US dollars, a sign of how much companies and people outside the US want to hold dollars and how hard that can be through local banking alone.
Where the value is heading
A few uses came up as the next wave rather than today's default:
- Programmable payments and AI agents that transact within set controls, since stablecoins are a fully programmable form of money. Think escrow that executes on its own terms, or finance workflows triggered through software rather than manual logins.
- Programmatic spend replacing cards for things like API usage, where a card charges a minimum fee on every transaction and a stablecoin payment carries none.
- Uncollateralized business credit, early today and plausible as instant, programmable settlement matures.
- More local businesses accepting stablecoins directly, which compounds through network effects as volume grows.
There is also a treasury angle. Companies sitting on idle cash, sometimes tens of millions, often earn nothing on it. Stablecoin earn products can route that balance into US Treasuries through providers like BlackRock and return north of 3%, with rewards accruing daily, and without the DeFi or smart-contract risk that earlier crypto products carried.
Questions worth asking before you adopt
The live Q&A surfaced the practical diligence most finance teams will want to do. A starting list:
- Custody. Does the provider hold your funds, or do you keep control through an on-chain account with your own approvers? Custodial setups are simpler, and they trade away some of the efficiency of operating in stablecoins directly.
- Security and redundancy. How are funds protected, and what happens if one service provider goes down?
- Reserves and transparency. Who is the issuer, how often do they disclose and attest, and who custodies the reserves?
- Redemption. Can you move between the stablecoin and cash one-to-one, same day, with no fee?
- Fees and minimums. Are there subscriptions, balance minimums, or locked features?
- Onboarding across PSPs. Who handles the KYB work with each payment partner, you or the platform?
- Reporting and reconciliation. How easily does activity flow into your close?
- Controls. Can you set multi-approver rules, permissions, and sub-accounts by function?
