What Is The US Dollar Index?

The US Dollar Index is used to give an average value for the relative performance of the US Dollar against other currencies. The value is calculated by comparing the dollar to a basket of currencies from major nations, including the UK, Canada and Switzerland.

The index is available as a spot and futures index, tracking the current and predicted values of the US Dollar against other currencies. The index has two common symbols: USDX and DXY.

There are several ways to start trading the US Dollar Index, including CFDs, ETFs, and options. Due to its ability to track the performance of the US Dollar independently of a single currency pair, the USDX is also used to hedge trades dependent on the value of the US Dollar.

How Does The US Dollar Index Work?

The current USDX components are made up of the Euro, Japanese Yen, Great British Pound, Canadian Dollar, Swedish Krona and Swiss Franc.

The USDX value calculation follows the formula:

  • 57.6% Euro
  • 13.6% Japanese Yen
  • 11.9% British Pound
  • 9.1% Canadian Dollar
  • 4.2% Swedish Krona
  • 3.6% Swiss Franc

However, a common criticism of the US Dollar Index is that its basket of currencies does not reflect all of the current major currencies and global trading powers.

Furthermore, the USD/EUR pair makes up almost 60% of the index composition, making it vulnerable to Euro-based fluctuations rather than USD-based determinants.

History

The US Dollar Index has a long history spanning half a century.

From 1944, major global currencies were pegged to the US Dollar, which was in turn pegged to the price of gold. The dollar was used as the global reserve currency and was exchangeable for gold at a fixed rate of $25 per ounce. This was known as the “Bretton Woods Agreement”.

However, the fixed value of the dollar caused issues when, in 1973, many considered the dollar overvalued. After mounting economic and global political pressure, then-president Richard Nixon ended the relationship between the US Dollar and gold. As a result of this news, many of the nations tied into the Bretton Woods agreement let their currencies float unpegged to the US Dollar.

In order for these newly unpegged global currencies to be tracked versus USD, the US Dollar Index was created in 1973. The index has been running since, allowing traders to access half a century of charts and historical data.

Today

The most recent news was in 1999, when the Euro replaced the various European currencies it previously followed. The US Dollar Index continues to track the USD in relation to several global currencies (EUR, JPY, GBP, CAD, SEK, CHF).

The USDX’s all-time high was in February 1985 when the index price reached close to 164.72 – almost 65 points above the base level of 100 that the index began at in 1973.

The all-time low of the USDX was during the 2008 financial crisis when the price fell to 70.698.

Price Determinants Explained

When making US Dollar Index performance predictions, it is important to understand the trading economics of the index. In addition to technical analysis, a good trader considers fundamentals.

So, want to know why the dollar index is rising or falling? Here are some of the main reasons for price movements:

Exposure To The Euro

The high weighting of the Euro within the US Dollar Index composition means that the price is highly susceptible to changes in the value of the Euro. This is because the index still uses a fixed weighting based on 1973 exchange rates, when currencies like the German Deutschemark and French Franc were in use.

A weaker Euro will usually lead to an increase in the price of the US Dollar Index, while a stronger Euro makes for a decreased DXY value. In addition, issues within a country that uses the Euro can lead to a loss of value in the currency, such as the recent struggles within Greece. Conversely, the Euro can be bolstered by positive announcements from the European Central Bank (ECB).

US Economic Health

As one would expect, central to the USDX trading economics is the financial health of the US nation. This is a multifaceted price determinant, encompassing factors such as employment rates, government debt data and stock market performance (such as the Dow Jones and Nasdaq).

US Dollar Inflation

Interest rates and inflation are integral to the US Dollar Index’s value. Adjusted inflation measures the increase in the price of a range of items and metrics, including food, wages, raw materials and commodity prices. This performance data has a significant impact on the strength and volatility of a currency.

When trading the US Dollar Index, investors can profit from predictions of upcoming interest rates and inflation announcements– especially on the futures markets. An interest or inflation rate above the market’s predicted value may increase the value of the USDX. The inverse is also true, with the US Dollar Index futures price potentially rising following a high interest rate or inflation announcement.

How To Trade The US Dollar Index

The US Dollar Index is a popular global asset, and investing can take many forms. Those that wish to trade the US Dollar Index can do so via ETFs, CFDs, mutual funds, options, and other instruments.

Traders can choose between spot and futures speculation on the USDX. The former trades on the current values of the basket of currencies, while the latter uses dated contracts for the future delivery of these assets. Futures are often more volatile than spot prices, which is important to acknowledge when building a trading strategy.

Here are some of the use cases for different instruments. Investors could:

  • Short the DXY using ETFs with 2x or 3x leverage
  • Use CFDs to access leverage of up to 1:500 long or short
  • Buy USD Dollar Index shares using a bullish mutual fund

Pros Of Trading The US Dollar Index

  • Diversification – Due to the basket of currencies used in the US Dollar Index calculator, the price is more reflective of the value of the USD than the other currencies.
  • Long and short options – It is easy to figure out how to short the USDX with many ready-made short ETFs in addition to ample CFD products.
  • Simple to understand – The price determinants of the US Dollar Index are relatively straightforward, with simple trading economics often behind why the dollar index is rising or falling.
  • Long-standing asset – The USDX has 50 years of historical prices and daily, monthly and real-time chart data to analyze.
  • Trading vehicles – Investors can trade the US Dollar Index via CFDs, ETFs, options and many more instruments.

Cons Of Trading The US Dollar Index

  • High EUR exposure – The USDX basket of currencies is made up heavily of the EUR/USD pair with almost 60% weighting. This means that changes vs the Euro can move the index significantly despite no changes in the dollar’s value.
  • Outdated composition – As its last update was in 1999, the USDX is missing some of the most significant and traded currencies now. For this reason, many investors favour the Trade Weighted Dollar Index.
