The U.S. Dollar Index (USDX or DXY) is a measure of the value of the U.S. dollar relative to a weighted basket of six major foreign currencies: the euro (57.6% weight), Japanese yen (13.6%), British pound (11.9%), Canadian dollar (9.1%), Swedish krona (4.2%), and Swiss franc (3.6%). Established in 1973 after the Bretton Woods system ended, the index serves as a benchmark for the dollar’s strength in global markets.
How the Dollar Index Drives Trade Directional Bias in Forex
Indicator of Dollar Strength or Weakness
When the USDX rises, it means the U.S. dollar is strengthening against this basket of currencies; when it falls, the dollar is weakening. Since the dollar is the world’s primary reserve and trading currency, its strength heavily influences forex market trends.
Correlation with Major Currency Pairs
Inverse correlation with EUR/USD and GBP/USD: Because the euro and pound have large weights in the index, a rising USDX typically causes EUR/USD and GBP/USD to fall, and vice versa.
Positive correlation with USD/JPY and USD/CAD: For pairs where USD is the base currency, these pairs tend to move in the same direction as the USDX.
Commodity-related pairs like AUD/USD and NZD/USD often move inversely to the USDX due to their sensitivity to global risk sentiment and commodity prices.
Guiding Trade Decisions and Confirming Signals
Traders use the USDX to confirm directional bias in forex trades. For example, if the USDX is rising, it supports taking long positions in USD-based pairs or short positions in pairs where USD is the quote currency. Conversely, a falling USDX suggests caution on USD longs and potential opportunities in other currencies.
Macro and Sentiment Indicator
The USDX reflects broader economic conditions, U.S. monetary policy, and global risk sentiment. For instance, Fed rate hikes often strengthen the USDX, causing shifts in forex markets. It also acts as a proxy for the health of the U.S. economy and influences global trade flows.
