The US dollar index (USDX) calculates how much the US dollar is worth in comparison to a basket of world currencies. It is a geometric weighted average of the value of the dollar in relation to six important currencies: the euro, the Japanese yen, the British pound, the Canadian dollar, the Swedish krona, and the Swiss franc.
The Bretton Woods system of fixed exchange rates failed in 1973, leading to the creation of the USDX. The index's starting value was 100, and since then, it has changed based on how strong or weak the dollar is perceived to be on the international market.
The performance of the dollar and the state of the US economy are both commonly measured using the USDX. A high USDX reflects the strength of the dollar and the ability to purchase more goods and services abroad. If USDX is low, the dollar is weak and can only purchase a smaller amount of goods and services abroad.
Together with commodities, bonds, and stocks, the USDX has an impact on other financial markets. For instance, a strong dollar tends to drive down the cost of goods denominated in dollars, such as gold and oil, as overseas buyers must pay more for them. Because they become more expensive for overseas customers when the dollar is weak, goods with a dollar price tend to cost more.
Similar to this, a strong dollar often entices overseas investors to purchase US bonds and stocks because they can earn higher returns on their investments. Due to the possibility of receiving lower returns on their investment, a weaker dollar tends to deter international investors from purchasing US bonds and stocks.
The USDX is a fluid and dynamic metric. During trading hours, it is updated every 15 seconds to reflect changes in the exchange rates between the dollar and its currency basket. Periodically changing the USDX can also reflect changes in the content or weight of its currency basket.
The USDX is not the only indicator of the dollar's worth. There are other indices that employ various currency baskets or computation techniques. The trade-weighted US dollar index, for instance, makes use of a currency basket to represent the US's trade patterns with other nations. Inflation and other variables that affect the purchasing power of currencies are taken into account by the real effective exchange rate (REER), which is another option.
The USDX is a helpful tool for traders, investors, and decision-makers who want to keep track of the patterns and movements of the dollar in comparison to other important currencies. But it's crucial to keep in mind that it's not an exhaustive or conclusive assessment of the dollar's worth. It is merely one of many indicators that might assist us in comprehending the intricate dynamics of the world currency market.
