Pre-Funding Is a Tax on Working Capital. Here's the Arithmetic.
The short answer
Pre-funding is capital you park in a destination currency before you've made the payment that needs it. It earns little, drifts against you, and has to be repeated for every currency you touch. On ten currencies it's a meaningful slice of working capital tied up in money you haven't spent yet.
The arithmetic
Say you settle across ten currencies and keep two weeks of average volume pre-funded in each. That's ~20% of monthly payment volume locked, permanently, across ten nostro accounts. The cost isn't a fee — it's the return on that capital, plus the FX move against you while it sits, plus the ops time to manage ten balances.
| Cost component | What you pay |
|---|---|
| Stranded capital | Return on the cash parked, forgone |
| FX drift | Movement against you while it sits unfunded |
| Corridors not opened | Pairs you skip because you can't fund them |
| Ops overhead | Ten balances to fund, monitor, reconcile |
Why it's invisible
Pre-funding shows up as "just how payments work," not as a line item. Nobody sends a bill for the capital you can't use. But the capital is gone all the same — and the corridors you don't open because you can't fund them are lost revenue you'll never see on a P&L.
Convert at execution instead of forecasting it. The money stays yours until the payment actually moves.
The alternative
On a stablecoin settlement rail you hold value in the token between legs and convert at the moment of payment. No pre-funding a currency you're waiting to spend. Working capital comes back into the business and stays there until it's needed.
The bottom line
Pre-funding is a tax you pay in opportunity cost, not invoices. The way to stop paying it is to stop funding destinations ahead of time.
What is pre-funding in payments?
Parking cash in a destination currency before you've made the payment that needs it. It earns little, drifts against you, and has to be repeated for every currency you touch.
How much working capital does pre-funding tie up?
If you settle across ten currencies and keep two weeks of volume pre-funded in each, that's roughly 20% of monthly payment volume locked across ten nostro accounts — capital you can't use.
How do you avoid pre-funding?
Hold value in the settlement token between legs and convert at the moment of payment, so the money stays yours until the payment actually moves.
