Currency exchange rates affect economies, businesses, and individuals across the world. Yet, most people rarely understand how they work. Whether you’re travelling abroad, running an import-export business, or simply shopping online, currency fluctuations impact your expenses. This guide explains why currency exchange rates change, what drives those shifts, and how they connect with global economic factors.
What Are Currency Exchange Rates?
A currency exchange rate is the price of one currency in terms of another. For example, if 1 US dollar equals 83 Indian rupees, that’s the exchange rate. These rates constantly fluctuate, driven by supply and demand in the foreign exchange market.
The foreign exchange market, often called Forex, is the world’s largest financial market. It operates 24 hours a day and facilitates trillions of dollars in daily transactions. Unlike the stock market, there is no central exchange. Instead, banks, financial institutions, corporations, and individual traders buy and sell currencies based on global events.
The Role of Supply and Demand in Currency Value
Currency value increases when demand rises. When demand falls, the currency value drops. The law of supply and demand governs exchange rate behaviour in every country. For instance, if foreign investors rush to buy Indian bonds, they need rupees. That increases demand for the rupee, strengthening its currency value.
Likewise, if more people sell the Indian rupee in favour of the US dollar, the rupee weakens. These fluctuations happen rapidly and affect everything from trade deals to tourism.
How Interest Rates Impact Currency Exchange Rates
Interest rates play a major role in shaping currency exchange rates. When a country raises its interest rates, foreign investors move their money there. They seek higher returns, which requires converting their currency into the local one. This increases demand for that country’s currency and strengthens its exchange rate.
Let’s say the US Federal Reserve raises its interest rates. Investors start buying US dollars to earn better returns. As a result, the dollar becomes stronger in the foreign exchange market.
Alternatively, if India cuts interest rates, foreign investors might withdraw their funds. That creates downward pressure on the rupee’s value and weakens its currency exchange rate.
The Connection Between Economic Performance and Currency Value
Strong economic performance increases confidence in a country’s currency. Investors want to put their money where growth is visible and stable. High employment, GDP growth, rising exports, and increasing business investments indicate a healthy economy.
When a nation experiences economic growth, its currency exchange rate often rises. On the contrary, weak economic data leads to lower investor confidence. That triggers capital outflows and weakens the currency.
For example, if Japan reports high GDP growth and innovation in technology, more investors want to buy yen. They trust that the currency will retain or grow in value. This increase in demand strengthens the yen’s exchange rate.
Political Stability and Market Sentiment Also Influence Currency Exchange Rates
Currency markets are highly sensitive to political changes. Stable governments attract foreign investors, boosting currency value. However, political instability causes panic and capital flight.
In 2016, when the UK voted for Brexit, the British pound crashed overnight. There was no immediate economic downturn, but fear drove investors away. Currency exchange rates dropped because of sentiment, not data.
Similarly, if a country holds elections and a business-unfriendly leader wins, investors might react negatively. This emotional shift can be stronger than any actual policy. Therefore, even rumours or speeches from political leaders can impact currency value.
Inflation Rates and Their Impact on Currency Value
Inflation erodes the purchasing power of money. When a country has high inflation, the value of its currency drops. Nobody wants to hold money that buys less each year.
Countries with low, stable inflation tend to have stronger currencies. Investors feel safer holding those currencies because their value remains more consistent.
For instance, Venezuela and Zimbabwe have experienced extreme inflation. As a result, their currencies lost almost all value in global markets.
On the other hand, countries like Switzerland or Germany, which maintain low inflation, enjoy stronger and more stable currency exchange rates.
Speculation in the Foreign Exchange Market
Currency trading isn’t just about facts. It also involves predictions and speculation. If traders believe the euro will rise, they start buying it. This pushes the currency’s value up—even before any economic change happens.
Speculation is driven by forecasts, technical analysis, and market psychology. Traders read trends, predict interest rate hikes, or follow global events closely. When large numbers act on a belief, their combined actions impact currency exchange rates.
That’s why news related to central banks, global health crises, or trade policies often causes immediate reactions in the currency market.
Trade Balances and Currency Strength
Countries that export more than they import enjoy a trade surplus. This is great for currency value. Foreign buyers must purchase the exporting country’s currency to pay for goods. More demand increases the currency exchange rate.
For instance:
- China exports large volumes of electronics.
- Buyers worldwide need yuan to pay.
- That drives up the demand for yuan.
- Result: stronger currency.
Countries with a trade deficit, like the US, import more than they export. This creates more supply than demand for the domestic currency, weakening its value.
How Central Banks Intervene to Manage Currency Exchange Rates
Central banks sometimes intervene to stabilise their currency. They buy or sell currencies in bulk to prevent extreme volatility.
If the Indian rupee weakens rapidly, the Reserve Bank of India might sell US dollars and buy rupees. This reduces supply and raises the rupee’s value. However, such interventions only offer short-term fixes.
Long-term currency strength depends on deeper factors like interest rates, economic performance, and investor sentiment.
Real-World Events That Shift Currency Exchange Rates
Let’s explore some recent examples:
- During the COVID-19 pandemic, the US dollar strengthened. It became a safe haven as markets crashed.
- In 2022, the US raised interest rates aggressively. That pushed the dollar to multi-decade highs.
- Political tensions between Russia and Ukraine weakened both currencies globally.
These events show that currency exchange rates react to global developments—often faster than any other market.
Why You Should Care About Currency Exchange Rates
Even if you’re not a trader, currency fluctuations affect your life. Here’s how:
- Travellers pay more or less depending on exchange rates.
- Importers and exporters see profits change with currency value.
- Freelancers earning in foreign currency face income variation.
- International students and families see higher or lower tuition costs.
Understanding how currency exchange rates work helps you plan better, spend smarter, and avoid losses.
