Currencies are always traded in pairs, because the price of one currency must be measured against another.
Reading a currency pair price
Example: EUR/USD = 1.1000
- The first currency (EUR) is called the Base Currency
- The second currency (USD) is called the Quote Currency
- This means 1 euro can be exchanged for 1.10 dollars
- If the price rises to 1.1100, it means the euro has strengthened or the dollar has weakened
Major pairs (Majors)
| Pair | Nickname | Notes |
|---|---|---|
| EUR/USD | Fiber | Most traded pair in the world |
| USD/JPY | Gopher | Sensitive to the US–Japan interest rate differential |
| GBP/USD | Cable | Relatively high volatility |
| USD/CHF | Swissie | The Swiss franc is a safe-haven currency |
| AUD/USD | Aussie | Linked to commodity prices and the Chinese economy |
| USD/CAD | Loonie | Linked to oil prices |
| NZD/USD | Kiwi | Linked to agricultural products |
Pairs that do not include the dollar, such as EUR/JPY or GBP/JPY, are called Cross pairs. Pairs that include an emerging-market currency, such as USD/THB, are called Exotic pairs, which have lower liquidity and wider spreads.
What is a pip?
A pip is the smallest conventional unit of price change.
- For most currency pairs, 1 pip = the 4th decimal place (0.0001). For example, EUR/USD moving from 1.1000 to 1.1025 = 25 pips
- For pairs involving the yen, 1 pip = the 2nd decimal place (0.01)
The Dollar Index (DXY)
The U.S. Dollar Index (DXY) measures the value of the dollar against a basket of 6 currencies. It started at 100 points in 1973.
| Currency | Weight |
|---|---|
| Euro (EUR) | 57.6% |
| Yen (JPY) | 13.6% |
| Pound (GBP) | 11.9% |
| Canadian dollar (CAD) | 9.1% |
| Swedish krona (SEK) | 4.2% |
| Swiss franc (CHF) | 3.6% |
DXY rising = the dollar strengthening overall, which often puts pressure on gold, commodities and emerging-market currencies. Because the euro has the largest weight, DXY tends to move in the opposite direction of EUR/USD.
DXY does not include the yuan or any Asian currency other than the yen, so it does not reflect the dollar's value against all of the United States' trading partners.
