Only rates this site has observed. It is not a complete market history, and a period with no entry means no change was recorded, not that the rate held steady.
The figure above is a mid-market reference rate: the midpoint between buying and selling, and the rate almost nobody is actually offered. A bank, wallet or remittance service adds a margin to it, and usually charges a fee on top. The margin is frequently the larger of the two and is rarely stated as a number.
UnifyPay tracks the published fees on each rail, not each provider’s FX margin, so this page cannot tell you which service gives the best rate. What it can tell you is what the transfer itself costs.
1 USD is 21.9468 STN, and 1 STN is 0.045565 USD, at the mid-market reference rate last refreshed on 8 Nov 2026.
Usually not. Banks, card issuers and transfer services add a margin to the mid-market rate and often charge a fee as well. The exchange-rate markup calculator shows how much of a quote is margin.
USD/STN is recorded directly against the US dollar. Indicative only, not a dealable quote, and not financial advice.
