What is the HMRC monthly average rate?
HMRC publishes official monthly average exchange rates for use in UK tax calculations. For June 2021, the HNL/GBP rate is 33.9100 — meaning £1 sterling buys 33.9100 Lempira.
These rates are published on the penultimate Thursday of each month and apply to the following month. They are the standard reference for HMRC-compliant tax reporting, including capital gains tax on the disposal of foreign assets.
To convert a HNL amount to GBP using this rate: divide the HNL amount by 33.9100.
Using this rate for capital gains tax
If you acquired or disposed of a foreign asset in June 2021, this HMRC monthly average rate is one of two acceptable rate sources for your capital gains tax calculation.
The other is the Bank of England daily spot rate on the transaction date. HMRC permits either — but you must apply the same source consistently across acquisition and disposal within a single asset calculation.
The choice of rate source can make a meaningful difference to your CGT liability. We calculate both automatically and show the sterling gain under each.
Step-by-step: HNL to GBP CGT calculation using the June 2021 rate
Convert acquisition cost
Take your original purchase price in HNL. Divide by the HMRC rate for the month of acquisition to get the sterling cost.
Convert disposal proceeds
Take your sale price in HNL. Divide by the HMRC rate for the month of disposal — which may be this rate if you sold in June 2021.
Calculate the gain
Subtract the sterling acquisition cost from the sterling disposal proceeds. The difference is your capital gain in GBP — reportable to HMRC.
Note on rate consistency: HMRC requires you to use the same rate source (monthly average or daily spot) for both acquisition and disposal within a single calculation. You cannot mix sources. We enforce this automatically and show the result under both sources side by side.

Frequently asked questions
What was the HNL exchange rate in June 2021?
The HMRC official monthly average exchange rate for Lempira (HNL) in June 2021 was 33.9100 HNL per £1 GBP. To convert a HNL amount to sterling, divide by 33.9100. For example, HNL 100,000 ÷ 33.9100 = £2,949.
What exchange rate do I use to report foreign income or capital gains to HMRC?
HMRC allows two approved rate sources: the HMRC monthly average exchange rate or the Bank of England daily spot rate (the 4pm fixing on the transaction date). Both are valid. For capital gains tax, using the more favourable rate can make a significant difference on large disposals. TealFX calculates your gain under both rates automatically.
Can I use the June 2021 HMRC monthly average rate for capital gains tax?
Yes. HMRC accepts the monthly average exchange rate as a valid method for converting foreign currency amounts to sterling for CGT purposes. You may use either the monthly average rate or the Bank of England daily spot rate — but must apply one source consistently across acquisition and disposal.
