Why Are Banks Adopting Stablecoins for Commercial Payments?

Why are banks adopting stablecoins for commercial payments?

Banks are adopting stablecoins because their commercial clients are asking for faster settlement, lower cost, and money that moves 24/7, and because US regulation now defines the perimeter a bank can operate in. Fifth Third, a top-10 US bank with almost $300 billion in assets, describes the shift as driven by operational efficiency rather than crypto exposure.

“The demand isn't coming from crypto companies; it's coming from commercial clients outside of the crypto space, looking for faster payments, lower cost, and better cash management.”

Igor Istratov leads digital assets products at Fifth Third, with a focus on Newline, the bank's API-first embedded finance platform. The episode is part of the Stablecoin Stories spinoff, which tells the story behind individual issuers and users of stablecoins.

What did Fifth Third change its mind about, and when?

Istratov places the turn in client demand: treasurers began asking why payments take days to settle, why they hold cash in several currencies, and why money cannot move on weekends. He adds a scale argument. With total stablecoin supply at roughly $300 billion by his reading of recent reports, Fifth Third's commercial payments volume alone is many multiples of that, so any stablecoin product must fit the bank's existing risk, compliance, and operational framework.

“Our commercial payments volume alone is many multiples of the entire stablecoin economy.”

Ran Goldi cited Fifth Third as processing more than $18 trillion in payments, which is why the bank treats the rail as production infrastructure rather than a side experiment.

Why now: client pain and regulatory clarity

Asked why this technology wins when faster domestic options exist, Istratov names two forces that converged: a real pain point on the client side and regulatory clarity. On the client side he points to cross-border settlement delays and valuation uncertainty between initiation and landing of a payment.

“banks don't move on ambiguity.”

On the regulatory side he cites OCC interpretive letters confirming national banks can provide crypto-asset custody and related services, and the GENIUS Act as the federal framework for payment stablecoins. Simon Taylor notes that the Clarity Act did not pass, but that for stablecoins the perimeter is clear enough to act.

What does a bank actually offer a stablecoin company?

Newline gives a digital asset company four account types on a top-10 bank balance sheet: an operating account for the company's own cash, settlement accounts for fiat settlement with exchanges and liquidity providers, reserve accounts holding the fiat behind issuance and redemption, and an FBO or custodial account that keeps eligible customers' fiat separate from company cash.

“It's just plumbing that has to be done right before anything interesting happens on top of it,”

— Igor Istratov, Digital assets products lead, Fifth Third Bank (Newline)

Istratov frames this as ordinary banking done carefully. The same structure gives issuers a path to reconcile high volumes, and it is why reserves become, in his words, a capital markets question as much as an operational one.

Cross-border: the Ohio manufacturer paying Thailand

Taylor asked whether a mid-sized Ohio manufacturer would use stablecoins or whether the business is mostly digital asset firms. Istratov answered both. A manufacturer paying suppliers in Thailand sends a wire through correspondent banks, hits cutoff times or a weekend, and receives confirmation days later with FX and fee uncertainty on top.

“a lot of our clients they really don't care that it's a stablecoin. They care that the money arrives today, and they want to know the cost of it in real time.”

— Igor Istratov, Digital assets products lead, Fifth Third Bank (Newline)

A stablecoin settlement leg gives near real-time movement, a known value at the time of the transaction, and traceability. The client does not need to care which technology sits underneath.

Do stablecoins compete with FedNow and real-time payments?

Istratov calls the tension between rails overstated. Domestically, real-time payments and FedNow are final, instant, and well understood. Stablecoins differentiate in cross-border payments and multi-currency accounts, where correspondent banking still dominates.

“I don't think that we will ever have too many rails in payments.”

— Igor Istratov, Digital assets products lead, Fifth Third Bank (Newline)

His preferred end state is rail-agnostic: the bank routes each payment to the rail that fits and handles orchestration, so the treasury team does not choose.

Deposit flight, partnerships, and the hard parts

On deposit flight, Istratov calls stablecoins a risk and an opportunity. Reserves have to sit somewhere and redemptions have to clear somewhere, which makes issuer banking a fee and deposit business. The larger risk is banks staying outside the market while deposits migrate.

“If stablecoins grow and banks are not a part of it, deposits migrate and banks lose the relationship.”

— Igor Istratov, Digital assets products lead, Fifth Third Bank (Newline)

He says the technology is not the hardest part. Banks must handle sanctions screening of on-chain counterparties, liquidity management for a rail that runs 24/7 while funding windows do not, reconciliation, client readiness, and the same risk, legal, compliance, and audit reviews as any other product. Taylor also cited a Capgemini World Payments Report finding that 60% of corporate treasury leaders would be open to stablecoin solutions from non-banks.

• Start from client pain. Istratov's test for a skeptical banker is whether clients complain about settlement times, park idle cash, or want payments to clear on a weekend (Stablecoin Stories, Oct 2026).
• Treat it as a commercial banking book. Most stablecoin flows today are business-to-business, covering service fees, payroll, and supplier payments, written somewhere other than a bank.
• Scale sets the bar. With about $300 billion of stablecoin supply against Fifth Third's $18 trillion-plus in payments, the product must meet existing risk and compliance standards.
• Route, don't replace. Stablecoins are another rail alongside RTP, FedNow, and same-day ACH, with the bank orchestrating which rail each payment uses.
• Hire bilingual teams. Product people who understand both protocol and regulatory layers, and will sit in risk committee meetings, get programs approved.
