Despite stablecoins reaching $5T in transaction volumes in 2025, their promise of cheaper cross-border payments is hampered by persistent foreign exchange costs
Even as stablecoins enter a period of peak expectations, veterans in wider fintech circles see limitations to the tokens as an emerging payments tool.
Context & Ripple Effects
The payments case for stablecoins has drawn growing institutional interest: Stripe, Revolut and other fintechs moved toward stablecoin launches, while banks were already exploring their own payment tokens amid Tether's rapid profitability.
This report tests that expansion narrative against the costly point stablecoins do not automatically remove: converting between currencies. High on-chain activity therefore does not by itself establish a cheaper end-to-end remittance or business-payment rail.
First-order effects
- Cross-border users and payment providers still bear foreign-exchange costs even when settlement occurs in stablecoins, limiting the immediate savings available from the token layer.
- The result separates transaction volume from payments utility: stablecoins can move value efficiently within a currency while the conversion into and out of local money remains a material cost.
Second-order effects
- Fintechs and banks pursuing stablecoin payment products will need to compete on FX execution, liquidity and local payout access—not solely on faster blockchain settlement.
- Issuers and payment platforms may concentrate first on corridors or flows that can remain in one currency, while multi-currency use cases retain the economics of conventional FX intermediaries.
Third-order effects
- If FX remains the binding constraint, stablecoins are more likely to become a settlement component inside existing cross-border payments stacks than a wholesale replacement for them.
- The gap between crypto transaction activity and end-user payment economics reinforces the regulatory concern around stablecoins' wider financial-market role: scale can grow before the consumer-cost proposition is proven.
The trend: Stablecoin adoption is shifting from a question of token issuance and on-chain volume to whether providers can solve the off-chain liquidity and FX infrastructure of real payments.
