I have $40,000 US in a bank in Canada (part of my Dad's estate) and I want to open a dollar account in the UK, where I live, banking on the dollar's recovery against the pound. The exchange has already moved from $2.00 to $1.76 per £1 in just the short time since I decided to let it ride. Which is the best UK dollar account for UK investors? I would want to be able to convert it to £££s quickly at the oportune moment.
