If you're diving into the world of market data, you'll quickly find that the forex (FX) market is the biggest of them all, with trillions of dollars traded every day.
Unlike stocks, you don't trade one thing in isolation. You're always trading one currency against another in a "pair." The most important of these are the "Major Pairs."
What makes them "Major"? Simple: every single one includes the United States Dollar (USD) 👑.
These seven pairs account for over 80% of all global forex trading. This massive volume means they have the highest liquidity (you can always buy or sell) and the lowest transaction costs (the "tightest spreads"). They are the "blue-chips" of the currency world.
Let's meet the seven Majors, their unique personalities, and their famous nicknames.
1. EUR/USD (The "Fiber")
- Pair: Euro / US Dollar
- How to Read It:
1 EUR = X USD
This is the king. The EUR/USD is the most traded financial instrument in the world, period. It represents a direct battle between the world's two largest economic blocs: the Eurozone and the United States.
- Key Characteristic: It's a "battle of the central banks." The price is almost entirely driven by the interest rate differential between the European Central Bank (ECB) and the U.S. Federal Reserve (Fed). Traders watch every economic report (like CPI and jobs) from both regions to guess what the central banks will do next.
- Nickname: "Fiber." A modern rival to "Cable," this nickname is said to come from the transatlantic fiber-optic cables that now transmit the pair's price data.
2. USD/JPY (The "Gopher")
- Pair: US Dollar / Japanese Yen
- How to Read It:
1 USD = X JPY
This is a fascinating pair driven by two contradictory forces. The Japanese Yen (JPY) is traditionally a "safe-haven" currency, meaning investors buy it in times of panic.
- Key Characteristic: The "Carry Trade" vs. the "Risk-Off" flow. For decades, the Bank of Japan (BoJ) has kept its interest rates near zero. This makes the
JPYthe ultimate "funding currency" for a carry trade: traders borrowJPYfor free to buy high-yieldingUSD(like U.S. bonds). This creates a constant upward pressure on theUSD/JPY. However, during a market crash, that all reverses as investors dump their risky assets and flee back to the "safety" of theJPY, causing the pair to fall. - Nickname: "Gopher" or "Ninja."
3. GBP/USD (The "Cable")
- Pair: British Pound / US Dollar
- How to Read It:
1 GBP = X USD
This is the original Major Pair, with a rich history. The GBP/USD is known for its high volatility and for being extremely sensitive to political news from both the UK and the US.
- Key Characteristic: The price is a direct reflection of the monetary policies of the Bank of England (BoE) versus the Fed. It's a "political" pair that can swing wildly on elections or major policy announcements.
- Nickname: "Cable." This is the most famous nickname in forex. It dates back to the 1860s, when the
GBP/USDexchange rate was transmitted between London and New York via the first transatlantic telegraph cable.
The "Commodity Currencies" (Comm Dolls)
These three pairs are known as "commodity currencies" because their countries' economies are heavily dependent on the export of raw materials. Their prices are powerfully correlated with global commodity prices.
4. AUD/USD (The "Aussie")
- Pair: Australian Dollar / US Dollar
- How to Read It:
1 AUD = X USD
The Aussie is a pure "risk-on" currency, meaning it does well when the global economy is optimistic and growing.
- Key Characteristic: The
AUDis a proxy for China. Australia is a massive exporter of iron ore and coal, and its #1 customer is China. When Chinese manufacturing data is strong, theAUDoften rises. As such, global traders use the Aussie as a 24/7 liquid way to bet on Chinese economic health. - Nickname: "Aussie."
5. USD/CAD (The "Loonie")
- Pair: US Dollar / Canadian Dollar
- How to Read It:
1 USD = X CAD
The Canadian Dollar is another major commodity currency, but it's linked to a different commodity.
- Key Characteristic: The
CADis a proxy for Crude Oil. Canada is one of the world's largest oil exporters (mostly to the U.S.). When oil prices rise, theCADstrengthens (causing theUSD/CADpair to fall). Forex traders often have an oil chart open right next to theirUSD/CADchart. - Nickname: "Loonie." This comes from the picture of a loon (a Canadian bird) on the Canadian $1 coin.
6. NZD/USD (The "Kiwi")
- Pair: New Zealand Dollar / US Dollar
- How to Read It:
1 NZD = X USD
The Kiwi is the Aussie's smaller sibling and is also a "risk-on" commodity currency.
- Key Characteristic: The
NZDis a proxy for agricultural prices, specifically dairy. New Zealand is the world's largest exporter of whole milk powder. The bi-weekly Global Dairy Trade (GDT) auction is a key event for Kiwi traders. - Nickname: "Kiwi." Named after the kiwi bird, the national symbol of New Zealand, which appears on its $1 coin.
The Other "Safe-Haven"
7. USD/CHF (The "Swissie")
- Pair: US Dollar / Swiss Franc
- How to Read It:
1 USD = X CHF
The Swiss Franc (CHF) is the world's other premier "safe-haven" currency.
- Key Characteristic: In times of extreme global panic, war, or financial crisis (a "risk-off" event), investors flee to the
CHFfor its unmatched history of stability, neutrality, and sound monetary policy. Its value often moves inversely to the rest of the market. The Swiss National Bank (SNB) is also a key driver, as it often intervenes to weaken theCHFwhen it gets too strong and hurts the country's exporters. - Nickname: "Swissie."
Conclusion
The seven Major Pairs are the foundation of the forex market. Each has a unique personality driven by its country's economy, commodity exports, or global risk status.
