The spot rate is USD 1.2500 per GBP. Expected annual inflation is 4% in the United States and 2% in the United Kingdom. Using purchasing power parity, what is the expected spot rate (USD per GBP) in one year?

The expected spot rate is USD 1.2745 per GBP. Under purchasing power parity the currency with higher inflation weakens, so the spot rate is multiplied by the ratio of US to UK inflation factors, 1.04 divided by 1.02.
