Suppose that the US is home country and the UK is foreign country and UIRP (uncovered interest rate parity) holds.
1, If the US interest rate falls, the current exchange rate between USD/GBP
(increases / decreases / no change). (assuming the UK interest rate and expected exchange rate do not change)
2, If people expect GBP to appreciate, this will lead to actual(depreciation / appreciation / no change)
of the GBP relative to USD. (assuming the UK and US interest rates do not change)
