International Fisher Effect
According to the Relative Version of Purchasing Power Parity Theory (PPP) one of the factors leading to change in exchange rate between currencies is inflation in the respective countries. As long as the inflation rate in the two countries remains equal, the exchange rate between the currencies would not be affected. When a difference or deviation arises in the inflation levels of the two countries, the exchange rate would be adjusted to reflect the inflation rate differential between the countries. The International Fisher Effect (IFE) theory is an important concept in the fields of economics and finance that links interest rates, inflation and exchange rates. Similar to the Purchasing Power Parity (PPP) theory, IFE attributes changes in exchange rate to interest rate differentials, rather than inflation rate differentials among countries. Nominal interest rates would automatically reflect differences in inflation by a purchasing power parity or no-arbitrage system. The two theories Continue reading
