I am planning a trip to the USA, for which I will need spending money. I have a brokerage account that is denominated in U.S. dollars and I would like, if possible, to use the proceeds from this so that I won't have to pay currency conversion fees. To do that I would have to withdraw the money to an account denominated in dollars. I am a UK citizen permanently resident in the UK and already hold a UK bank account denominated in sterling. Would a British bank allow me to open another account, held in the UK but denominated in U.S. dollars, and if so, which ones?
There are plenty of questions about opening a bank account with a bank in the U.S.. I don't want to do that, as it appears that generally one has to physically present at the bank in question to open an account. I am asking about opening an account with a British bank, but denominated in a currency other than sterling.
