About CPI n.s.a — United Kingdom
DEFINITION
The UK’s CPI n.s.a registered at 143.600000 in August, up from July’s 142.900000, indicating a continued rise in consumer prices. This month-over-month increase reflects ongoing inflationary pressures in the UK economy. Market participants will closely watch upcoming data for further inflation trends amid current monetary policy conditions. Updated 9/16/26
WHY THIS INDICATOR MATTERS
Inflation prints feed directly into central-bank policy expectations and real-yield calculations, and are among the most rate-sensitive releases on the calendar. The release is more useful as part of a longer-run signal than as a single-print catalyst. Released monthly.
WHAT CHANGED THIS MONTH
Latest reading (Aug 2026): actual 143.6.
