A weighted collection of selected currencies used to measure the value of another currency or to peg an exchange rate. The U.S. Dollar Index (DXY) and IMF Special Drawing Rights (SDR) are examples of currency baskets.
What a Currency Basket Is
A currency basket combines multiple currencies with specific weightings to create a composite benchmark. Central banks use baskets to manage exchange rate policy, economists use them to measure trade-weighted currency values, and the International Monetary Fund (IMF) uses a basket (the SDR) as an international reserve asset.
Common Currency Baskets
The most widely followed basket is the U.S. Dollar Index (DXY), which measures the U.S. Dollar (USD) against six currencies: Euro (EUR) (57.6%), Japanese Yen (JPY) (13.6%), British Pound (GBP) (11.9%), Canadian Dollar (CAD) (9.1%), Swedish Krona (SEK) (4.2%), and Swiss Franc (CHF) (3.6%). The heavy euro weighting means DXY closely mirrors EUR/USD movements.
The IMF's Special Drawing Rights (SDR) basket includes the dollar, euro, Chinese Yuan (CNY/CNH), yen, and pound. Some countries peg their currencies to a trade-weighted basket rather than a single currency, providing more stability against the range of currencies they actually trade in.
Trading Applications
Traders use the DXY as a benchmark for overall dollar strength. A rising DXY suggests broad dollar strength, while a falling DXY indicates broad weakness. Individual pair analysis should supplement DXY monitoring.
