The Currency of Capital As The Functional Currency or Not

Hello everyone.

There is a company that has their capital in USD while their sales and expenses are in the local currency. So I have been thinking for a while about the whether is best to use the currency of the company’s capital account as the functional currency even if the currency of the capital account is a foreign currency or the local currency should be used instead?

I have been searching for the Prons and Cons of using a foreign currency as the main currency of the company, but I couldn’t find any useful information.

I hope that I was able to explain the matter clearly and I also hope that there are some experienced accountants who can help.

Best regards
