Using a diagram(s), explain how the exchange rate will be determined in a free-floating exchange rate system.
In a free-floating exchange rate system, the exchange rate is primarily determined by market forces of supply and demand in the foreign exchange market. Here's an explanation of how the exchange rate is determined in such a system:
Supply and Demand for Currency: The exchange rate is influenced by the supply and demand for different currencies. When a country's currency is in high demand, its value tends to appreciate, and when the demand for a currency is low, its value tends to depreciate. The supply and demand for currencies are driven by various factors, including trade flows, capital flows, interest rate differentials, economic indicators, geopolitical events, and market sentiment.
Relative Interest Rates: Differences in interest rates between countries can affect the exchange rate. Higher interest rates in a country can attract foreign investors seeking better returns on their investments. This increased demand for the country's currency can lead to its appreciation. Conversely, lower interest rates can lead to a decrease in demand for the currency and potential depreciation.
Trade Balance and Capital Flows: The balance of trade, which includes exports and imports, influences the demand for a country's currency. If a country has a trade surplus (exports exceed imports), there is typically a higher demand for its currency to pay for those exports. This increased demand can lead to currency appreciation. Conversely, a trade deficit (imports exceed exports) may lead to currency depreciation. Capital flows, such as foreign direct investment (FDI) and portfolio investments, also affect the exchange rate as they involve the conversion of one currency into another.
Market Speculation: Market participants, including investors, speculators, and financial institutions, play a role in determining exchange rates through their expectations and actions. If they anticipate currency appreciation, they may buy the currency in advance, leading to an increase in demand and potential appreciation. On the other hand, if there is an expectation of currency depreciation, market participants may sell the currency, increasing its supply and potentially causing depreciation.
Central Bank Intervention: While exchange rates in a free-floating system are mainly market-driven, central banks may intervene in the foreign exchange market to influence their currency's value. Central bank interventions can take the form of buying or selling currencies to stabilize or manage excessive fluctuations. However, the impact of central bank intervention on the exchange rate is often limited and temporary in a free-floating system.
It's important to note that exchange rates in a free-floating system can be volatile and subject to short-term fluctuations based on market dynamics. The exchange rate determination process reflects the continuous interaction of market participants, economic fundamentals, and expectations.
