The exchange rate is the backbone of global trade and international finance. It defines the value of one currency in relation to another, shaping how nations, businesses, and individuals interact economically. Every import, export, or investment involves an exchange rate decision.
In the forex market, exchange rates form the foundation of all trading activity. Traders speculate on fluctuations, while governments and central banks monitor and influence them to protect national interests. Understanding exchange rates is therefore essential for anyone involved in forex trading, economics, or international business.
An exchange rate is the price of one currency expressed in another currency.
Exchange rates constantly move due to supply and demand. According to Investopedia, they are among the most important drivers of global finance, influencing trade, tourism, investment, and central bank policy.
A fixed exchange rate is when a government or central bank ties its currency’s value to another major currency, such as the U.S. dollar or gold.
A floating exchange rate is determined entirely by supply and demand in the market, without a government-set peg.
A pegged exchange rate is a hybrid model where a currency is tied to another but allowed to move within a narrow band.
A managed float system combines floating rates with periodic intervention. Central banks step in to stabilize extreme volatility.
The formula is simple:
Exchange Rate = Value of Currency A ÷ Value of Currency B
Example
If 1 EUR = 1.10 USD → Exchange Rate (EUR/USD) = 1.10
When no direct quote exists:
EUR/JPY = EUR/USD ÷ USD/JPY
Table Example
| Currency Pair | Quote Example | Meaning |
| EUR/USD | 1.10 | €1 = $1.10 |
| GBP/JPY | 185.50 | £1 = ¥185.50 |
| USD/CHF | 0.92 | $1 = CHF 0.92 |
After World War II, nations built a system to stabilize global finance. Under the Bretton Woods system, most currencies were pegged to the U.S. dollar, and the dollar was linked to gold at $35 per ounce.
By the late 1960s, rising deficits and war spending undermined confidence. In 1971, President Nixon ended gold convertibility, leading to the system’s collapse.

After Bretton Woods, currencies began to float. Rates now adjust based on supply and demand, with central banks occasionally intervening.
According to the Bank for International Settlements, daily forex turnover exceeded $7 trillion in 2024.
Exchange rates are central to forex trading strategies and economic policy. Platforms like Fastpip emphasize that traders must follow both technical charts and macroeconomic drivers such as interest rates, inflation, and trade balances.
Currency values are not just market figures; they mirror a nation’s economic strength, competitiveness, and the level of trust held by global investors. From rigid pegs to flexible floating regimes, the evolution of foreign exchange systems has shaped international trade and capital flows for decades.
For traders, businesses, and policymakers, it is essential to grasp how currency valuation works, what factors drive it, and how these movements impact the broader economy. A solid understanding of these dynamics enables better decision-making in today’s interconnected financial markets.
Always combine technical analysis with fundamental factors when trading currencies. Exchange rates can react sharply to central bank announcements, inflation data, or geopolitical tensions. Following experienced traders on Fastpip helps you stay aligned with professional strategies.
