Key points
- The US Consumer Price Index (CPI) tracks price changes paid by households and is published monthly by the US Bureau of Labor Statistics.
- Core CPI leaves out food and energy costs to reveal underlying price trends.
- Inflation above market expectations keeps the Federal Reserve cautious, which usually supports the dollar and pressures gold.
- Gold volatility spikes upon release, ranking #2 by gold’s first-hour range among the 15 events Fundora tracks.
- Gold’s first-hour price range after recent releases was typically 3.6 times the same hour on ordinary days.
What is US CPI inflation?
The Consumer Price Index (CPI) measures the average change over time in prices paid by US households for consumer goods and services. Published monthly by the US Bureau of Labor Statistics, it serves as the main benchmark for US consumer inflation. The report details both month-over-month and year-over-year price shifts across categories such as housing, transportation, medical care, and recreation.
Market participants watch two main versions: headline CPI and core CPI. Headline CPI reflects the total cost of all consumer items. Core CPI leaves out food and energy. Food and energy prices often swing sharply due to weather or geopolitical shocks, so core CPI provides policymakers with a clearer view of persistent price pressures. The Federal Reserve defines its 2% inflation target using Personal Consumption Expenditures (PCE) inflation, but CPI arrives earlier each month and serves as a key leading indicator for interest rate decisions.
When is it released?
The US Bureau of Labor Statistics publishes the CPI report monthly, usually around the middle of each month for the prior month’s data. The official release occurs at 08:30 local time in New York. For international traders tracking GMT, this corresponds to 12:30 GMT while New York is on summer time and 13:30 GMT during the rest of the year.
| Date | Time | Period |
|---|---|---|
| 10 November 2026 | 13:30 GMT | October 2026 |
| 10 December 2026 | 13:30 GMT | November 2026 |

Why it matters for gold and the dollar
CPI data directly influences expectations for Federal Reserve interest rates. When inflation numbers deviate from consensus forecasts, the shift in rate expectations triggers rapid adjustments across currency and precious metals markets.
The economic mechanism works through bond yields and currency valuations. If inflation prints higher than markets expect, the Fed faces pressure to keep interest rates elevated or tighten policy further. Higher interest rates push US Treasury yields up and attract capital to the dollar. Because gold yields no interest and is priced in dollars, higher yields raise the opportunity cost of holding the metal, while a stronger dollar makes gold more expensive for foreign buyers. Under these conditions, the dollar tends to rise while gold usually falls.
Conversely, if inflation comes in lower than anticipated, traders expect potential rate cuts or an end to monetary tightening. Treasury yields tend to soften, and the dollar often loses ground against major currencies. A weaker dollar makes gold cheaper for international buyers, and falling bond yields decrease the opportunity cost of holding non-yielding bullion, creating favorable conditions for gold to rise.
How gold usually reacts
Gold experiences sharp price volatility immediately after the CPI release. Among the 15 events Fundora tracks, CPI ranks #2 by gold’s first-hour range. Across the 5 releases since 10 June 2026, the first-hour range after the release was typically 3.6 times the same hour on ordinary days, reflecting the heavy surge in orders hitting the market.
| Release | After 15 min | After 1 hour | First-hour range |
|---|---|---|---|
| 14 October 2026 | −$59.9 | −$63.0 | $75.0 |
| 11 September 2026 | +$12.7 | +$48.8 | $106.6 |
| 12 August 2026 | +$0.9 | −$9.0 | $58.8 |
| 14 July 2026 | — | +$51.5 | $74.7 |
| 10 June 2026 | — | +$7.6 | $40.9 |
Gold (XAU/USD, US dollars per ounce) from the price at the release minute; Fundora's calculation from delayed market data. A dash: no 15-minute candles for that day.
Recent data highlights this volatility. Over these 5 releases, gold recorded a median first-hour range of $74.7 and a median one-hour move of $48.8. The directional move saw gold rise 3 times and fall 2 times in the first hour. Its biggest one-hour move was −$63.0.
Gold does not automatically rise or fall simply because inflation is positive. Directional movement depends on how the reported figures compare to market forecasts. A high print that falls short of expectations can cause the dollar to weaken and lift gold, whereas an upside surprise can trigger an immediate drop in gold prices.
Recent figures
Recent inflation readings show shifting price pressures across the US economy. Headline annual inflation peaked in May 2026 at 4.2%, alongside a month-over-month increase of 0.5%. Price pressures then moderated over the summer, with headline annual CPI declining to 3.5% in June 2026 and holding at 3.4% across July and August 2026.
| Period | CPI y/y | CPI m/m | Core y/y | Core m/m |
|---|---|---|---|---|
| September 2026 | 3.7% | 0.6% | 2.6% | 0.3% |
| August 2026 | 3.4% | 0.4% | 2.4% | 0.3% |
| July 2026 | 3.4% | 0.1% | 2.5% | 0.2% |
| June 2026 | 3.5% | −0.4% | 2.6% | 0.0% |
| May 2026 | 4.2% | 0.5% | 2.9% | 0.2% |
| April 2026 | 3.8% | 0.6% | 2.8% | 0.4% |

Core inflation also softened during this period, declining from 2.9% year-over-year in May 2026 to 2.4% in August 2026. However, price pressures reaccelerated in September 2026, when headline annual CPI rose to 3.7% alongside a 0.6% monthly gain. With the Federal Reserve maintaining an official inflation target of 2% on PCE inflation, headline and core readings well above that level continue to shape interest rate expectations.
How to prepare for the release
Trading the CPI release requires disciplined risk management and realistic execution expectations. The surge in market activity around 08:30 New York time quickly alters standard trading conditions.
