What Are Exchange Rates?
Exchange rates represent the value relationship between two currencies, determined by supply and demand dynamics in the forex market. As the most liquid financial market globally, forex trading involves analyzing currency fluctuations for informed financial decisions. This guide explores exchange rate mechanisms, key influencing factors, and practical analysis techniques.
Definition of Exchange Rates
An exchange rate is the conversion ratio between two currencies. For example, if USD/TWD is 1:32.41, one US Dollar equals 32.41 New Taiwan Dollars.
How Exchange Rates Are Determined
Exchange rates aren't set by a single entity but emerge from collective market participation:
- Market-driven pricing: Banks, corporations, and investors influence rates through trading activities.
- Central bank interventions: Occasionally, monetary authorities stabilize extreme fluctuations.
Core Principles of Exchange Rate Formation
- Supply-demand balance: Increased currency demand raises its value; excess supply decreases it.
- Relative valuation: Currency strength depends on comparative economic health (e.g., EUR/GBP during Brexit).
Key Factors Influencing Currency Values
Economic Growth
- Strong GDP growth attracts foreign investment, boosting currency demand.
- Higher productivity enhances export competitiveness (e.g., USD's global dominance).
Inflation Rates
- High inflation erodes purchasing power, triggering capital outflows.
- Low inflation maintains export advantages (e.g., JPY's historical stability).
Political/Economic Stability
- Geopolitical crises cause volatility (e.g., wartime currency collapses).
- Stable governance fosters investor confidence (e.g., CHF's safe-haven status).
