US economic data release calendar

When does the next CPI come out? When does the debt number move? The official release rhythm of the data this platform serves — and the moment the API picks each release up.

CPI releases — remaining 2026 dates

The Bureau of Labor Statistics pre-announces every CPI release for the year. All releases at 8:30 AM ET. The reference month is always the month before the release date.

Dates per the official BLS CPI release schedule (the BLS occasionally reschedules — the official page is always authoritative). The December 2026 CPI is released in January 2027, on the 2027 schedule.

National debt — every business day

The publication pattern

  • The Treasury publishes each business day's Debt to the Penny figure one business day later, around 3:00 PM ET.
  • No annual calendar needed — it's daily, weekends and federal holidays excluded.
  • The source never froze during federal shutdowns (verified through Oct–Nov 2025).

Interest rates & annual series

  • Average interest rates: monthly, published with the Treasury's month-end data.
  • Historical Debt Outstanding (1790+): one new record per fiscal year end (September 30).

What this means for your integration

Ingestion is automatic on every release. CPI and famous prices refresh on release day; the debt refreshes every business day after publication. Your code never has to know the calendar — but if you poll, these dates are when polling pays.

Poll cheaply: every response ships ETag — send If-None-Match and unchanged data costs you a 304. On release days, the new month simply appears in /inflation/latest.

Missing months stay missing. If the government doesn't publish (e.g. October 2025, federal shutdown), the API serves the hole as null — never an estimate.
