Stablecoins Won't Replace SWIFT

FX & Float: Operator Note

In 2008, Satoshi Nakamoto published a nine-page paper titled “Bitcoin: A Peer-to-Peer Electronic Cash System.” The vision, as the name states, was a new way to send payments directly between two parties without going through a financial institution. Bitcoin was designed to be money that moves freely.

It did not turn out that way. Bitcoin is now digital gold - a store of value, rather than a medium of exchange. The volatility that makes it attractive as a speculative asset makes it useless for payments. You cannot price a cross-border invoice in something that can move 15% in a day.

Stablecoins now claim to finish what Satoshi started. They are price-stable, blockchain-native, and fast. Their promise is compelling enough that serious people have begun arguing that SWIFT’s days are numbered. Yet stablecoins have inherited Bitcoin’s original problem in a different form - hype.

The hype around stablecoins is based on a misdiagnosis. The misdiagnosis is that the bottleneck in cross-border payments lies in the messaging layer. SWIFT is a messaging network, and yes, a very old one. But upgrading the messaging layer solves roughly 10% of the problems. The other 90% is everything else: compliance screening, FX conversion into local currency, last-mile delivery to the recipient’s account, and regulatory reporting in both jurisdictions. All of these remain even after you change the rail.

Let’s say someone sends a $50,000 payment from the US to Vietnam. Stablecoins can move USDC between two wallets in seconds. But the recipient in Vietnam does not want USDC. They want VND in their bank account, with legally compliant documentation. This requires a licensed entity in Vietnam with banking relationships, local FX liquidity, and the compliance infrastructure to process the transaction legally. All of this is identical to what traditional cross-border payments require. While stablecoins skip the middle correspondent banking chain, they do not eliminate the hard parts at either end.

Compounding this is a liquidity problem the hype consistently ignores. Stablecoins need deep liquidity across every corridor they serve. This liquidity exists for major currencies but not for emerging ones. Who provides deep USDC-to-NGN liquidity at 2 AM in Lagos? Either a centralised market maker who will charge for the service, or nobody. Thin liquidity erodes the cost advantage that stablecoins promise. And unlike SWIFT, where a failed transaction has established legal frameworks and dispute resolution mechanisms behind it, a stablecoin transaction that gets stuck leaves you with no counterparty to call. The absence of intermediaries is a defining feature of crypto. In cross-border payments, it increases the risk manifold.

As regulation catches up, compliance requirements will increasingly mirror those of established payments companies. The cost advantage will narrow. A licensed, compliant stablecoin provider will need much the same infrastructure as everyone else.

This does not mean stablecoins have no role. There are two use cases where the case for stablecoins is genuinely strong. The first is wholesale settlement between institutions that both natively hold stablecoins. Crypto exchanges settling with each other is the clearest example. They have no conversion at either end and no last-mile problem. The second is in corridors where traditional infrastructure is broken or absent. In parts of Africa, Southeast Asia, and Latin America, a stablecoin rail with a functioning local off-ramp can outperform the alternatives. Stablecoins help leapfrog the existing infrastructure with something much better.

Outside these two cases, stablecoins will compete on the same dimensions as everyone else – cost, speed and reliability. This is the honest version of the stablecoin payments thesis. It won’t become a SWIFT killer, but a specialised rail for specific corridors and counterparty types where conditions are right.

Satoshi wanted to reinvent money. Stablecoins want to finish the job. They will find their place. It will just be narrower than the hype suggests, and more durable than the sceptics admit.
