Final answer:
If the US has higher inflation than the UK, the GBP/USD exchange rate should see the British pound appreciate against the US dollar.
Step-by-step explanation:
Given that the United States is expected to have higher inflation than the United Kingdom, there are potential implications for the value of the GBP/USD exchange rate. Typically, if a country has higher inflation, its currency tends to depreciate because the purchasing power of the currency declines relative to other currencies. In this scenario, if the U.S. dollar (USD) is facing higher inflation, it should weaken against the British pound (GBP). Consequently, we would expect to see the value of the GBP/USD to appreciate. Therefore, the value of one British pound would increase in terms of how many U.S. dollars it can buy, as an international investor might hope for the pound to go from buying $1.50 in U.S. currency to buying $1.60.
