US Dollar Index (DXY) — Dollar Strength Chart

The dollar is the world's reserve currency. When it rises fast, emerging markets and commodities come under pressure. When it falls, that pressure eases. This chart shows the dollar against six major currencies.

US Dollar Index (DXY)

Measures the value of the US dollar against a basket of major currencies. For growth analysis, lower DXY change indicates better conditions for market growth.

Why this can crash the market

A fast-rising dollar tightens conditions everywhere at once. Much of the world borrows in dollars, so a stronger dollar raises the cost of every foreign loan. At home, a large share of S&P 500 revenue is earned abroad and converts back into fewer dollars, so earnings get marked down even when business is fine.

What Is the US Dollar Index?

The DXY measures the US dollar against six major trading-partner currencies. It started in 1973 and is the main benchmark for dollar strength.

Currency Weights

  • Euro (EUR): 57.6%
  • Japanese Yen (JPY): 13.6%
  • British Pound (GBP): 11.9%
  • Canadian Dollar (CAD): 9.1%
  • Swedish Krona (SEK): 4.2%
  • Swiss Franc (CHF): 3.6%

Key Levels

  • Below 90: Weak dollar — commodity boom territory
  • 90-100: Neutral range
  • 100-110: Strong dollar. Pressure on emerging markets.
  • Above 110: Very strong. Risk of global stress.

How Dollar Strength Impacts Markets

Strong Dollar (Rising DXY)

  • US multinational earnings hurt by currency conversion
  • Commodity prices fall (priced in dollars)
  • Emerging market debt stress increases
  • US imports become cheaper, exports more expensive

Weak Dollar (Falling DXY)

  • Boosts US corporate earnings abroad
  • Commodity prices typically rise
  • Emerging markets and international stocks rally
  • Can signal inflation concerns if sustained

What Drives Dollar Strength?

The main driver is the rate difference between the Fed and other central banks. When the Fed raises rates faster than the ECB or the Bank of Japan, money moves into dollar assets for the higher yield. Political uncertainty also pushes safe-haven money into the dollar. Large trade deficits weigh on it over the long term.
