Providers advertise settlement speed as a feature. It is mostly a function of which rail they reach, and the rail also determines the cost. The figures below assume a provider that itemises, and [a crypto to fiat exchange](https://collectnexchange.cy/services/crypto-offramp) is one.

## Instant regional schemes

Seconds, including weekends and outside business hours. Cost of effectively nothing.

A provider connected, directly or through a partner, can settle on a Sunday evening. One that is not cannot.

The question to ask is whether instant settlement reaches an external bank account or only the provider's internal balance. The marketing frequently blurs this and the difference is total.

## Standard regional transfers

Same or next business day, subject to a cut-off. Cost of one to five units.

Every institution has an afternoon cut-off. A payment submitted after it processes the next business day, which over a weekend means three days.

Cut-offs are rarely published prominently. Asking is worth the email and submitting before noon removes the problem entirely.

## Correspondent banking

One to four business days. Twenty to fifty in fees, taken by intermediary banks along the chain, plus the currency margin where a conversion occurs. Payment companies face a different cost stack, which [a regulated European crypto platform](https://collectnexchange.cy/) addresses.

Any intermediary can decline, and you will usually be told only that the payment was returned with a fee deducted.

## Domestic rails outside the region

Vary enormously, and provider coverage is uneven. For a business settling outside its home region this is the question that determines whether the arrangement works at all.

## The cost implication

The rail choice and the currency choice are the same decision in practice.

Settling in the currency the provider holds, to an account in the same region, uses the cheap fast rail. Anything else reintroduces the expensive slow one.

## The treasury implication

When settlement took days, holding a fiat balance with a provider was necessary.

Where it is instant, a balance is optional, and a balance with a provider is a credit exposure to that provider.

Any process built around slow rails is worth revisiting on that basis.

## The three questions

The cost that only appears on a bad day is the absence of support, and whether [a crypto exchange with published fees](https://collectnexchange.cy/services/crypto-exchange) exists is worth establishing.

Which rails do you reach, for which currencies, to which countries.

What are the cut-off times.

Does instant settlement reach an external bank or only an internal balance.

They determine more than any feature comparison.
