QUESTION 1 [15 MARKS]
Foreign Exchange Market and Tariffs
The foreign exchange market (FOREX) determines the price of one currency in terms
of another through supply and demand (Mankiw, 2021). Here, the South African Rand
(ZAR) is exchanged for the Chinese Yuan (CNY). An increase in Chinese tariffs on
South African exports raises the price of South African goods, reducing Chinese
demand for imports (Krugman & Obstfeld, 2022). Since Chinese importers must
exchange CNY for ZAR to pay exporters, reduced import demand lowers demand for
ZAR in the FOREX market.
Under a flexible exchange rate, this decline shifts the demand curve for ZAR leftward
while supply remains constant. The new equilibrium exchange rate (R₂) is below the
initial rate (R₁), leading to depreciation of the ZAR and appreciation of the CNY (World
Bank, 2023). Protectionist policies like tariffs thus weaken exporters’ competitiveness
and reduce currency demand.0717513144
