What is the DXY index?

The DXY index (US Dollar Index) measures the value of the US dollar against a basket of six major currencies: Euro (57.6%), Japanese Yen (13.6%), British Pound (11.9%), Canadian Dollar (9.1%), Swedish Krona (4.2%), and Swiss Franc (3.6%). It was established in 1973 with a base value of 100.

No. DXY is a currency index, not a stock, so you cannot buy shares of it directly. The 'DXY stock price' people search for is really the index quote, which is what the live chart on this page shows. Traders get exposure through ICE dollar index futures, options, or dollar-tracking ETFs rather than by owning DXY itself.

Why does gold go up when the dollar goes down?

Gold is priced in US dollars globally. When the dollar weakens, gold becomes cheaper for holders of other currencies, increasing demand. Additionally, a falling dollar often reflects inflation concerns or monetary easing, both of which drive investors toward gold as a safe haven.

What DXY level is bullish for gold?

There’s no fixed level, but gold tends to rally when DXY drops below key support levels or enters a sustained downtrend. Historically, gold bull markets have coincided with periods of DXY weakness below 90 to 95. The correlation isn’t perfect though: both can rise simultaneously during global uncertainty.

How often is the DXY updated?

The DXY trades nearly 24 hours a day on ICE Futures exchange, from Sunday evening to Friday afternoon (US Eastern time). Our charts update in real-time during trading hours with data sourced from major exchanges.

Does the DXY affect silver and platinum too?

Yes, the inverse dollar relationship applies to all precious metals, not just gold. Silver, platinum, and palladium are all priced in USD and tend to benefit from dollar weakness. However, these metals also have significant industrial demand components that can override the dollar correlation.

DXY Chart (US Dollar Index)

The DXY chart above plots the US Dollar Index in real time, with historical ranges available from intraday moves out to multi-year trends. Because the index is a weighted average of six exchange rates rather than a single pair, the chart smooths out one-currency noise and shows the dollar's broad direction, which is exactly what precious metals traders care about.

When reading the DXY chart alongside gold or silver, watch for trend breaks rather than day-to-day wiggles. A sustained move through a prior support or resistance level on the dollar index has historically preceded multi-week moves in dollar-priced metals.

DXY Today: Live Dollar Index

The DXY today updates nearly 24 hours a day, five days a week, as ICE futures and the underlying currency pairs trade from the Sydney open on Sunday evening through the New York close on Friday. The live quote at the top of this page reflects the latest traded level of the DXY dollar index, along with its change on the session.

Context matters more than the raw number: a DXY reading near 100 sits at the index's original 1973 parity level, well above the 2008 all-time low of 70.70 and far below the 1985 record of 164.72. Comparing today's level against those benchmarks, and against the 90 and 110 zones traders watch, tells you whether the dollar is historically strong or weak right now.

Understanding the US Dollar Index (DXY)

The US Dollar Index (DXY) measures the value of the US dollar against a basket of six major currencies: the Euro (EUR), Japanese Yen (JPY), British Pound (GBP), Canadian Dollar (CAD), Swedish Krona (SEK), and Swiss Franc (CHF). The Euro carries the largest weight at approximately 57.6%.

Gold and the US Dollar Index historically share a strong inverse correlation. When the dollar strengthens (DXY rises), gold prices tend to fall because gold becomes more expensive for holders of other currencies, reducing demand. Conversely, when the dollar weakens (DXY falls), gold prices tend to rise as it becomes cheaper in non-USD terms and investors seek alternative stores of value.

Tracking the DXY alongside precious metals gives traders and investors context for price movements. A sharp decline in DXY often signals potential upside for gold, silver, and other commodities priced in US dollars.

DXY Currency Basket Breakdown

The DXY is heavily weighted toward the Euro (57.6%), making EUR/USD the dominant driver of the index. This means European Central Bank (ECB) policy decisions can move the DXY significantly, which in turn affects gold and other precious metals pricing globally.

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

For precious metals traders, understanding this composition is critical. Because the Euro dominates the basket, a strong move in EUR/USD can shift the DXY even if other currency pairs remain stable. This Euro-centric weighting means ECB rate decisions, Eurozone inflation data, and European political events can all indirectly impact gold prices through their effect on the dollar index.

How to Use DXY for Precious Metals Trading

The DXY provides practical trading signals for precious metals investors. When the DXY breaks below key support levels, metals often rally as the weaker dollar increases foreign buying power. Conversely, a DXY breakout above resistance can signal headwinds for gold and silver.

One of the most powerful signals is divergence: when gold rises alongside a rising DXY, it indicates extreme safe-haven demand that's overriding the normal inverse relationship. This scenario has historically preceded major gold bull runs, as it suggests systemic concerns are driving capital into both the dollar and gold simultaneously.

For a more complete picture, combine DXY analysis with real yields (inflation-adjusted Treasury yields). When the DXY is falling and real yields are negative, conditions are highly favorable for precious metals. When DXY is rising but real yields are falling, metals may still find support despite dollar strength.

DXY Historical Context and Key Levels

The DXY reached its all-time high of 164.72 in February 1985, during the Plaza Accord era when the strong dollar was crushing U.S. exports. The subsequent coordinated intervention to weaken the dollar sent gold prices higher over the following years. The all-time low was 70.70 in March 2008, during the global financial crisis, which coincided with gold's explosive rally toward its then-record highs.

Key psychological levels traders watch include 100 (the original parity baseline), 90 (historically a major support zone that, when broken, has signaled dollar weakness and metals strength), and 110 (a resistance level that has capped several dollar rallies).

Major macro events have consistently demonstrated the DXY-gold relationship. The Plaza Accord (1985) drove the DXY from 164 to below 90, fueling gold. The 2008 financial crisis pushed the DXY to its all-time low while gold surged. During COVID-19, the initial dollar spike gave way to a slide toward 90 through 2020, and gold reached then-record highs above $2,000 per ounce that August. Understanding this historical context helps traders identify where current DXY levels sit relative to past cycles.
