Hi BPS WONG,
We have limited information in the question, which makes it difficult to reply to.
Please see Capital Gains (CG) mauual 78320 and CG78321 which gives information on this and states that whilst the currency held in there is treated as an asset, these accounts are now
dealt with like a simple debt and so in themselves give rise to no gain or loss.
CG78315 also advises that where a individuals is simply buying currency for personal use there will also be no chargeable gain.
However, where a individuals is using his foreign currency account to buy and sell non-sterling currency (in this case HKD) in order to make gains, then as currency is
lassed as an asset as per CG78300.
Any disposals made could give rise to a chargeable gain for CGT purposes.
