HSC Economics — Topic 1
Exchange Rates — Flashcards & Quiz
Exchange rates connect Australia's economy to the rest of the world and recur every year in HSC Economics. You need to explain the factors driving demand and supply for the AUD — interest rate differentials, commodity prices, capital flows, speculation, and relative inflation — and predict how appreciation or depreciation flows through to exports, imports, inflation and the current account. Distinguish the floating regime from fixed and managed alternatives, and use the Trade Weighted Index when discussing competitiveness.
Sample Flashcards
Q1: What is an exchange rate and how is the AUD determined?
An exchange rate is the price of one currency in terms of another currency. Australia operates a floating exchange rate system where the value of the Australian dollar is determined by supply and demand in the foreign exchange market. Demand for AUD comes from exports, foreign investment into Australia, and speculation. Supply of AUD comes from imports, Australian investment abroad, and speculation. The RBA does not set a target exchange rate but may intervene to smooth excessive volatility.
Sample Quiz Questions
Q1: Under a floating exchange rate system, the central bank does not intervene in the foreign exchange market.
Answer: FALSE
While floating exchange rates are primarily determined by market forces (supply and demand), central banks may still intervene to smooth excessive volatility or address disorderly market conditions. This is called a "managed float" or "dirty float". The RBA does not target a specific exchange rate but has intervened occasionally to reduce extreme fluctuations. The key difference from fixed rates is that the central bank does not commit to maintaining a specific value.
Q2: The Australian dollar is often described as a "commodity currency" because its value is closely linked to commodity prices.
Answer: TRUE
The AUD is heavily influenced by commodity prices, particularly iron ore, coal, and LNG, because commodity exports comprise over 60% of Australia's total exports. When commodity prices rise, export earnings increase, raising demand for AUD and causing appreciation. When commodity prices fall, the AUD typically depreciates. This close correlation with commodity prices, especially China's demand for resources, makes the AUD a "commodity currency" alongside currencies like the Canadian dollar and Norwegian krone.
