What Is a Currency?
A currency is the official medium of exchange in a country or group of countries. It’s issued by a central bank or monetary authority and used for trade, debt settlement, and storing value. In the forex market, currencies are bought and sold in pairs, and their relative values shift constantly based on economic data, interest rates, and global events.
Every currency traded in the forex market is identified by an ISO 4217 code. When you see EUR/USD, that means you’re trading the Euro against the US Dollar. Understanding the basics of forex trading starts with knowing the currencies involved.
Major World Currencies

Major currencies are the most heavily traded in the world. They all pair with the USD and have high liquidity, tight spreads, and significant daily volume. These are the eight major currencies:
| Currency | ISO Code | Symbol | Country/Region | Central Bank |
| US Dollar | USD | $ | United States | Federal Reserve (Fed) |
| Euro | EUR | € | Eurozone (21 countries) | European Central Bank (ECB) |

Minor (Cross) Currency Pairs
Minor currencies, also called crosses, are major currencies paired against each other without involving the US Dollar. Common examples include EUR/GBP, AUD/JPY, and GBP/CHF. They have decent liquidity but wider spreads than the majors.
Here are some commonly traded minor currency pairings:
| Pair | Base Currency | Quote Currency | Typical Spread |

| GBP/JPY | British Pound | Japanese Yen | Medium |

How Currencies Are Classified in Forex Trading
- In forex, currencies aren’t just listed alphabetically. They’re categorized by their role in the global economy and how actively they’re traded. Here’s how the classification breaks down:
- Reserve currencies: Held by central banks as foreign exchange reserves. The USD, EUR, JPY, GBP, CHF, AUD, and CAD fall into this category.
- Commodity currencies: AUD, CAD, and NZD tend to move with commodity prices like oil, gold, and iron ore.
- Pegged currencies: Some currencies are fixed to another, like the Bahraini Dinar and Qatari Riyal, which are pegged to the USD.
- Floating currencies: Most major and minor currencies float freely based on supply and demand in the open market.
Understanding how currencies behave is crucial before placing any trade. You can learn more about how to read currency exchange charts to get a practical edge.
The ISO 4217 Standard: Currency Codes Explained
Every currency in global use has a three-letter ISO 4217 code. The first two letters typically represent the country, and the third represents the currency name:
- USD = US (United States) + D (Dollar)
- GBP = GB (Great Britain) + P (Pound)
- JPY = JP (Japan) + Y (Yen)
- EUR = EU (European Union) + R (added for distinction)
There are also X-codes for special purposes. For example, XAU is the ISO code for gold and XAG for silver, which is why you’ll see these listed as tradable instruments on MT5 platforms.
At Defcofx, you can trade currency pairs alongside precious metals, all from a single MetaTrader 5 account.
How Many Currencies Can You Trade in Forex?

| Major Pairs | 7 | EUR/USD, USD/JPY, GBP/USD, USD/CHF, USD/CAD, AUD/USD, NZD/USD |
| Minor/Cross Pairs | 20–25 | EUR/GBP, AUD/JPY, GBP/JPY, EUR/CHF |

Final Thoughts on List of World Currencies
Currencies are the foundation of the global financial system, facilitating trade, investment, tourism, and economic growth across every country and region. While there are around 180 officially recognized currencies worldwide, only a small group dominates global forex trading, international reserves, and cross-border transactions.
For traders, understanding the differences between major, minor, and exotic currencies is essential. Major currencies offer the highest liquidity and tightest spreads, making them ideal for most trading strategies. Minor and exotic currencies can provide unique opportunities, but they also come with higher volatility and wider trading costs.
Beyond trading, understanding currency classifications, ISO codes, central bank influence, and exchange rate dynamics helps build a stronger foundation for navigating financial markets. Whether you are trading EUR/USD, monitoring commodity currencies like AUD and CAD, or exploring emerging market pairs, success starts with knowing how currencies function and what drives their value.
