US Dollar Index (DXY or USDX) Live

About US Dollar Index: Meaning, Calculation, Importance & Live Market Insights

The US Dollar Index (DXY or USDX) is one of the most widely monitored financial indicators in the global currency markets. Introduced in 1973 by the Intercontinental Exchange (ICE), the US Dollar Index measures the value of the U.S. dollar relative to a basket of six major world currencies. It serves as a benchmark for evaluating the dollar’s strength and is essential for forex traders, commodity traders, multinational companies, and global investors.

Because the U.S. dollar is the world’s primary reserve currency, changes in the US Dollar Index influence global trade flows, commodity prices, stock markets, and international capital movements. Traders closely watch US Dollar Index Live charts to understand global risk sentiment, inflation expectations, and monetary policy outlook.

What Is the US Dollar Index (DXY)?

The US Dollar Index measures the dollar’s performance against a basket of six major currencies:

1. Euro (EUR) – 57.6% weight
2. Japanese Yen (JPY) – 13.6%
3. British Pound (GBP) – 11.9%
4. Canadian Dollar (CAD) – 9.1%
5. Swedish Krona (SEK) – 4.2%
6. Swiss Franc (CHF) – 3.6%

The euro holds the largest weight because it represents several European countries that use a common currency. DXY rises when the dollar gains strength against this basket and falls when the dollar weakens.

How the US Dollar Index Is Calculated

The index calculates the value of the U.S. dollar based on a geometric weighted average of the six currencies in the basket. The formula considers the exchange rates and the assigned weights for each currency.

Mathematically, the US Dollar Index is derived from:

• Real-time forex market prices
• Historical base value of 100 (set in 1973)
• Weighted adjustments for each currency pair

A reading above 100 indicates the dollar is stronger than its 1973 benchmark level, while a reading below 100 indicates weakness.
