HMRC exchange rates for March 2021

143 currencies, as HMRC published them for 1 to 31 March 2021. Each figure is the number of units you get for one pound.

Divide, do not multiply

Sterling is the foreign amount divided by the rate in this table. Multiplying instead is wrong by the square of the rate, which on a typical dollar figure is more than half as much again.

HMRC do not prescribe which exchange rate you use. CG78310 expects a reasonable and consistent method, and the monthly rate is the method this calculator applies to every trade. What CG78310 does settle is the date: sterling worth is taken at the date of the acquisition or disposal (Bentley v Pike, Capcount Trading v Evans). A broker's own rate and a market feed are neither published nor consistent, so this site never reads one.

Rates are shown exactly as published and are not rounded, because the calculator divides by the same figure. A currency with no name against it is one this server holds only by code.

Where this month came from

Months from January 2021 onwards come from the Online Trade Tariff, which publishes one CSV per month. This is the file for March 2021:

https://www.trade-tariff.service.gov.uk/api/v2/exchange_rates/files/monthly_csv_2021-3.csv

Ask that service for a month before January 2021 and it answers 404, which is the same answer it gives for a month nobody has published yet. Those months come from HMRC's XML archive instead.

The collection that lists both is Exchange rates for customs and VAT on gov.uk. Nothing here is taken from a mirror. A rate comes from HMRC or it does not come at all.

Upload a broker export and every foreign trade in it is converted at the HMRC rate for its own month, with the month named in the report. The guide explains the matching rules that decide which cost a disposal takes.
