HMRC exchange rates for January 2018

145 currencies, as HMRC published them for 1 to 31 January 2018. 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 before January 2021 come from HMRC's own XML archive, which is what the gov.uk collection links to for monthly rates up to December 2020. This is the file for January 2018:

http://www.hmrc.gov.uk/softwaredevelopers/rates/exrates-monthly-0118.XML

The same file is also served with a lower case extension, at http://www.hmrc.gov.uk/softwaredevelopers/rates/exrates-monthly-0118.xml, and HMRC's own index is inconsistent about which. The host is case sensitive, so both spellings are tried. The file carries a Period attribute and a rate is kept only when that attribute names the month asked for, because a wrong month URL still answers 200 with a complete and valid looking file.

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.
