Why Does Gold Rise When the Dollar Falls?
Gold tends to rise when the dollar falls because gold is priced in dollars, pays no interest and competes with bonds. A weaker dollar makes an ounce cheaper for everyone who earns another currency, and falling real interest rates make a non-yielding asset cheaper to hold.
The link is real but loose: since 2006 the correlation between monthly changes in gold and in the broad dollar index is -0.29, and it has not been constant. Gold is $4,044 an ounce as of October 28, 2026.
Why does a weaker dollar lift the price of gold?
There are three reasons, and they overlap.
- Pricing. Gold's global price (XAU/USD) is quoted in dollars. When the dollar falls against other currencies, a buyer paid in euros or yen needs fewer of them per dollar's worth of gold, so demand for the same ounce can rise.
- Opportunity cost. Gold pays nothing. With the 3-month Treasury bill at 4.06% in October 2026, holding one $4,044 ounce means giving up about $164 a year in interest (an illustration that ignores tax and storage).
- Safe-haven demand. Investors sometimes buy gold when they lose trust in a currency or expect trouble. That demand is real but hard to measure, so this post gives no number for it.
The second reason is why real interest rates matter more to gold than nominal ones. The 10-year real yield was 2.82% in October 2026, and monthly changes in gold and in that yield had a correlation of -0.30 since 2003 (-0.22 over the past three years).
What does the data say about gold and the dollar?
Using the Federal Reserve's broad dollar index (January 2006 = 100, 119.2 in September 2026) and month-end gold prices, here is how they moved over non-overlapping windows, the same method as the dollar vs gold page:
| Window | Observations | Correlation with the dollar index |
|---|---|---|
| Monthly changes, since 2006 | 248 | -0.29 |
| Monthly changes, past three years | 36 | -0.42 |
| Quarterly changes, since 2006 | 82 | -0.39 |
| December-to-December changes, 2007 to 2025 | 19 | -0.64 |
Longer windows show a stronger link because the noise averages out. But a correlation only says they usually move opposite ways, not by how much.
41 quarters each, March 2006 to September 2026, quarter-end values. Gold rose in 33 of 41 and 20 of 41.
Is the link between gold and the dollar constant?
No. The same monthly correlation, measured over rolling three-year windows, ranged from -0.45 (the window ending August 2026) to +0.09 (ending September 2015), and it was positive in only 5 of 213 windows. By period:
| Period | Months | Correlation |
|---|---|---|
| 2006 to 2009 | 47 | -0.30 |
| 2010 to 2014 | 60 | -0.27 |
| 2015 to 2019 | 60 | -0.23 |
| 2020 to 2022 | 36 | -0.26 |
| 2023 to September 2026 | 45 | -0.40 |
The sign held in every period, but the strength changed. The calendar years show the exceptions: in the 9 years the dollar index fell, gold rose in all 9 (an average +25.5%). In the 10 years it rose, gold averaged just +0.3%, but the range ran from -25.4% to +28.0%. In 2024 the index rose 6.5% and gold still gained 28.0%.
What else moves gold besides the dollar?
Real yields, inflation expectations, central-bank buying and investor fear all matter. Gold is also 23.4% below its February 2026 month-end high of $5,278, while the dollar index is down only 0.7% over the year to September 2026, so the dollar alone does not explain the recent path. Gold is down 1.6% over one year and up 125.6% over five (October 28, 2026).

Gold and dollar FAQ
Does gold always go up when the dollar falls?
No. In the 41 quarters since 2006 when the broad dollar index fell, gold rose in 33 (80%). In the 41 quarters when the dollar rose, gold still rose in 20 (49%).
Why is gold priced in dollars?
The global benchmark price, XAU/USD, is quoted in US dollars, so a dollar that loses value against other currencies makes an ounce cheaper for foreign buyers and tends to raise the dollar price.
What is the opportunity cost of holding gold?
Gold pays no interest or dividend. With the 3-month Treasury bill at 4.06% in October 2026, an ounce worth $4,044 gives up about $164 a year in interest, an illustrative figure that ignores tax and storage.
How do real yields affect gold?
A higher real yield raises the return on safe bonds and so the cost of holding gold. Monthly changes in gold and in the 10-year real yield had a correlation of -0.30 since 2003, with the real yield at 2.82% in October 2026.
Can gold rise while the dollar rises?
Yes. In 2024 the broad dollar index rose 6.5% from December to December while gold rose 28.0%. The link between the two is a tendency, not a rule.
