Dvdci

Hello, I have question about CGT on foreign currency received as dividend and held in broker account. Namely, I own some shares which are traded in GBP but dividend is paid in USD. For dividend tax, my understanding is that I have to convert USD amount with FX rate on the date dividend is received to GBP and pay the tax on that amount. However, I don't convert USD dividend back to GBP on the same day I receive it and instead I leave it in USD and then convert to GBP from time to time. My question here is if I am subject to CGT on foreign currency in this case? I have read the rules stating that Foreign Currency Bank Accounts are not subject to CGT, however, it is a bit unclear if that also covers broker account and my case. The broker is Interactive Brokers UK. I don't trade foreign currencies and the sole purpose of FX conversion I do is to convert dividend back to GBP. Thank you
