At a glance
Stablecoins are not a remittance rail. They are not built to move fiat across major currency corridors; for most G20 payments a token does not remove the correspondent, it swaps a credit-rated bank for a crypto exchange and adds two conversions.
Key distinction: a stablecoin changes the messaging in the middle of a payment, not who holds the funds at the start and the end. That custody chain, not the rail, determines cost and settlement timing.
The Money2020 narrative is that stablecoins are quietly becoming the world's settlement layer. The volumes tell a more specific story: the genuine traction sits in a handful of use cases, while the "stablecoins replace cross-border" claim runs into the same structural reality every time. The funds still have to leave the token and arrive in a bank account.
What a stablecoin actually replaces
Consider a euro-to-Singapore-dollar payment routed through stablecoins. The path is rarely euro to token to Singapore dollar. It is euro to US dollar, dollar to USDC, USDC back to dollar, and only then dollar to Singapore dollar, often with the receiving exchange waiting for the US dollar leg to settle before it buys local currency.
That is two conversions and two spreads wrapped around the same dollar leg a correspondent payment would use anyway. The stablecoin has not removed an intermediary. It has substituted a AAA-rated correspondent for a crypto exchange in the destination market, and asked the platform to pay for the round trip.
For markets where correspondent banking already reaches, this is more expensive than the system it claims to improve. The hidden cost is not in the headline fee. It is in the conversion layer, the same place embedded FX markup hides in conventional cross-border flows.
Swift is not the bottleneck
The instinct is to blame the rail. But the messaging layer is not where cross-border payments stall. As we have argued in settlement chain, a Swift message crosses the world in seconds; the delay lives in how each correspondent manages its nostro and vostro balances, liquidity, and compliance checks.
Stablecoins do not fix that. They still sit on top of banking, and they still settle into central-bank money at the edges. You cannot pay a beneficiary's payroll in a token they cannot bank. The correspondent banking decline of more than 20% since 2011, documented by the BIS, is a problem of bank incentives and balance-sheet economics, not a problem a faster message solves.
Swapping the rail without changing who holds and releases the funds leaves the actual friction in place. It simply moves it inside a different intermediary.
Where stablecoins genuinely move value
There are two places the remittance framing does hold, and they are narrower than the hype suggests:
- Dollar-illiquid markets. Where local participants cannot buy dollars at all, a dollar-reflective token is genuinely useful. But this is a short-term workaround. At scale, that liquidity runs out, and regulators eventually cap the very access the token was exploiting.
- Markets without trust in the local currency. Where merchants do not want to hold local currency, collecting in stablecoins and banking outside the home country is a durable pattern. Here the value is not speed. It is avoiding a currency the holder never wants to touch.
In both cases the stablecoin is an exit, not a rail. It is the way value leaves the digital world and lands in a bank somewhere it is trusted. That is a real job. It is not the same job as clearing a G20 corridor.
The infrastructure underneath, either way
Whichever use case applies, the funds resolve into a bank deposit. Someone holds the dollars backing the token, and someone provides the fiat on the other side. That someone is a correspondent institution. The token is the easy part; the custody, settlement, and compliance around it are the hard part, and they do not disappear because the middle hop went on-chain.
This is why the durable infrastructure question is not "which token" but "who clears and holds the funds." Platforms that need to move money across borders are better served by multi-currency clearing with predictable settlement and named custody accounts than by a rail that adds a conversion to dodge a correspondent they still depend on.
Lorum is a globally licensed specialist correspondent institution holding six regulatory licences across multiple jurisdictions. It operates a non-lending, 100% reserve model focused on three functions: multi-currency clearing across 30+ markets, named custody accounts, and cash management including wholesale FX. For fintech and PSP platforms, the strategic advantage is not in chasing the rail. It is in owning the custody and clearing the rail was always going to settle into.
Frequently asked questions
Are stablecoins good for cross-border payments?
Only in specific cases. For markets where correspondent banking already reaches, stablecoins usually add conversions rather than remove intermediaries. Their genuine value is in dollar-illiquid markets and markets without trust in the local currency, where the token is an exit into a trusted bank rather than a general-purpose remittance rail.
What is the "stablecoin sandwich"?
It is the round trip a stablecoin payment often takes: for example, euro to dollar to USDC to dollar to the destination currency. The token sits in the middle of two fiat conversions, each with its own spread, which is why it can cost more than a direct correspondent payment.
Do stablecoins replace Swift?
No. Swift moves messages, not money, and it is not the bottleneck in cross-border settlement. Stablecoins change the messaging layer but still settle into bank deposits and central-bank money at the edges, so the underlying custody and settlement work remains.
If not remittance, what are stablecoins actually for?
Their durable role is moving value out of the digital world and into the physical one, settling agentic or on-chain activity and then resolving into a bank account. That is a real function, but it is an off-ramp, not a replacement for clearing major currency corridors.
