Stablecoins and the collapse of legacy payment rails

The industry consensus for years was that stablecoins would sit alongside cards and ACH as another payment method. That framing is dying quickly. Stablecoins do not slot into the existing value chain — they collapse it.

A traditional cross-border payment involves at least four intermediaries: the sender's bank, a correspondent, a receiving bank, and a network. Each captures a cut. Each adds latency measured in days. Each requires separate compliance and reconciliation. That entire stack compresses into a single transfer with programmable metadata when the base currency is a dollar-denominated token.

This is not a marginal improvement. It is the same discontinuity we saw when VoIP flattened the long-distance market.

The winners are not the ones who tokenize a fiat currency. They are the ones who own the surface where the tokenized dollar meets the real world: exchange listings, corporate treasury, merchant acceptance, payroll, remittance corridors. Each of those surfaces is worth a public company on its own.

The losers are correspondent banks, card networks that never modernize, and every fintech built on top of the assumption that ACH will remain the settlement layer of last resort.
