Congratulations! You get a phone call from one of your company's clients. The client wants to know, assuming that PPP holds, what should the Malawian Kwacha (MKD) versus South African Rand (SAR) exchange rate (quoted as the number of MKD per SAR) be in two years time (i.e., on April 24th 2024)? You have the following information: The expected inflation rates for Malawi and South Africa for each of the next 2 yoars will be as follows: Malawirs annual inflation rate for each of the next 2 years is expected to be 15% por annum. South Africa's annual inflation rate for each of the next 2 years is expected to be 5% per annum. The current spot exchange rate is 55.0 MKD = SAR1 (ie, 55.0 MKD per SAR).
