HMRC exchange rates 2021
Every HMRC monthly period rate published for 2021 — 12 months, around 140 currencies each. These are the rates to use when converting a 2021 transaction for a VAT return, a customs declaration or a correction: the rate that applies is the one for the period the transaction falls in, not the rate in force when the paperwork is done.
The year in the main currencies
High, low and average of the published monthly rates across 2021. HMRC issues each month on its own and publishes no annual summary, so this comparison is ours.

1.3775 | 5.1% | -0.2% |
The widest swing among these was JPY, ranging 13.0% between its lowest month (January 2021) and its highest (November 2021). For a business invoicing in that currency through 2021, that is the size of the reporting difference between one month and another on an otherwise identical invoice.
