Always check the actual figure against the consensus forecast — the gap between the two usually moves markets more than the number alone.","market_impact":"The upside surprise reinforced bets that the Federal Reserve could raise interest rates at its next meeting rather than hold or cut. That typically pushes bond yields and the dollar higher while pressuring stocks, especially rate-sensitive sectors like tech and real estate.","what_it_means":"CPI tracks how much prices consumers pay are rising. In August, prices rose 0.4% from the prior month (up from 0.1% in July) and held at 3.4% year-over-year, above the 3.3% economists forecast. Core inflation (excluding food and energy) eased slightly to 2.4% annually but rose 0.3% for the month, more than expected. Gasoline, up 3.9%, drove over a third of the monthly increase."},"source_url":"https://www.bls.gov/news.release/archives/cpi_09112026.htm","occurred_at":"2026-09-12T16:04:13.433+00:00","published_at":"2026-09-12T16:04:13.433+00:00","brief_url":"https://vectorialdata.com/economia/2026-09-11-us-us-cpi-august-2026/brief.md","page_url":"https://vectorialdata.com/economia/2026-09-11-us-us-cpi-august-2026","json_ld":{"@context":"https://schema.org","@type":"Dataset","name":"US CPI (August 2026) — 2026-09-11","description":"US CPI (August): Inflation holds at 3.4% YoY, hotter than expected","creator":{"@type":"Organization","name":"Vectorial Data","url":"https://vectorialdata.com"},"license":"https://vectorialdata.com/terms","variableMeasured":"US CPI (August 2026) (% YoY)","temporalCoverage":"2026-09-11","isAccessibleForFree":true,"distribution":[{"@type":"DataDownload","encodingFormat":"application/json","contentUrl":"https://vectorialdata.com/api/economic-events/2026-09-11-us-us-cpi-august-2026"},{"@type":"DataDownload","encodingFormat":"text/markdown","contentUrl":"https://vectorialdata.com/economia/2026-09-11-us-us-cpi-august-2026/brief.md"}]},"disclaimer":"Vectorial Economía is descriptive educational information about macro data.
