How do exchange rate changes affect the economy?

Exchange rate changes affect an economy through their influence on trade, inflation, investment, and overall competitiveness. When a currency appreciates, it becomes stronger relative to other currencies. This makes imports cheaper, which can reduce inflation by lowering the cost of foreign goods and raw materials. However, a stronger currency also makes exports more expensive for foreign buyers, reducing demand for domestically produced goods abroad. Exporting firms may face falling revenues, and industries dependent on international sales can lose competitiveness.

Conversely, when a currency depreciates, exports become cheaper and more attractive to foreign markets. This can boost production, increase employment in export-oriented sectors, and strengthen economic growth. However, depreciation also makes imports more expensive, which can increase inflation. Higher import prices especially affect countries reliant on foreign food, fuel, or manufactured goods. If inflation rises too quickly, households’ purchasing power declines, creating economic instability.

Exchange rate movements also influence investment flows. A strong and stable currency attracts foreign investors who want to protect the value of their returns. Depreciation, however, may cause investors to withdraw funds if they expect further losses, increasing financial volatility. Exchange rate uncertainty can discourage long-term investment, as firms face unpredictable costs and revenues.

Finally, exchange rate changes shape government policy decisions. Central banks may adjust interest rates to stabilise the currency, especially if rapid depreciation threatens inflation. In open economies, exchange rate management becomes an important part of maintaining macroeconomic stability.

FAQs

How does a stronger currency affect consumers?

A stronger currency makes imported goods cheaper, allowing households to buy foreign products at lower prices. This reduces inflation and increases purchasing power. Travelling abroad also becomes more affordable. However, if domestic industries struggle due to reduced export competitiveness, job losses may occur. Consumers benefit in the short term but may face long-term consequences if the economy becomes less competitive globally.

Why can depreciation boost economic growth?

Depreciation makes exports cheaper and more competitive in global markets. As foreign buyers purchase more domestic goods, firms expand production and hire more workers. This can stimulate broader economic growth, especially in export-heavy economies. However, the benefits depend on the structure of the economy and whether firms can increase output without facing higher production costs.

Can exchange rate changes cause inflation?

Yes. A depreciating currency makes imports more expensive, raising production costs for firms and increasing consumer prices. This is known as imported inflation. If depreciation is rapid or persistent, inflation can rise quickly, forcing central banks to intervene. Conversely, currency appreciation lowers import prices and can help reduce inflation.
