The building blocks of your rate

  • The reference rate — the official NAFEM window level the bank starts from.
  • A margin (spread) — the bank adds a cut for providing the FX and taking the risk.
  • Fees — card, transfer or processing charges on top.

Why card and cash rates differ

International card spend is usually converted at a rate close to the official window plus a margin, within monthly limits. Cash and parallel transactions follow the street rate, which sits higher. So the “rate” depends entirely on the channel.

How to judge a fair rate

Compare any quote against the live USD to Naira rate and the street level, and read what a good dollar-to-naira rate is so you know what “good” looks like before you commit.
