Capital loss c/f revaluation

Hello there, I made an investment in USD and upon its disposal in 21/22 incurred a capital loss - given forex change am I allowed to revalue non-GBP capital losses b/f using a current tax year exchange rates (and going forward until the loss is fully utilised)? Thank you.

clarification let's say, I converted GBP into 30,000 USD in order to make an investment into an asset. During 21/22 tax year I disposed this investment at a capital loss of 10,000 USD (say, 7500£ at the time). Do I a) carry forward 7500 GBP of capital loss only or b) revalue capital loss of 10,000 USD using current tax period GBP/USD rate or c) revalue capital loss of 10,000 USD into GBP at a time when this loss is set off against capital gains? I would appreciate some guidance. Thank you.

Hi MP2,
No, the loss is based on the figure reported in the year it occurred.
Thank you.
