Hi peacemaker
1. For US holidaymakers coming to the UK, then the exchange rate looks good. Anyone wanting to transfer money from the US to the UK, yep, it's favourable. Reality is that in the big picture, there's really not much traffic in those two elements.
2. The UK is in far worse overall shape than the US.
3. Theoretically, exports will do better - however, demand is substantially reduced overall as credit to finance those new cars is harder to come by now.
As this is a UK/USA focussed site, and the worlds trading currency being the US dollar, many items, financials, trade is linked to the USD. The UK costs more to do business in, so prices will inevitably go up here as the pound weakens. There's a whole lot more to it of course but from a consumer level, that's about the size of it right now.
