# Why Nikkei 225 (JP225) fell 1.16% on October 21, 2026

Nikkei 225 (JP225) fell 1.16% on October 21, 2026 — UK inflation fears sour global risk appetite.

## What happened

The Nikkei 225 slipped 1.2% after UK inflation jumped to 3.5%, its highest in nearly a year.

## Why it moved

A hotter UK print raises the odds that central banks keep rates higher for longer, which lifts global yields and pressures rate-sensitive equities.

## Why it matters

No specific theme attaches here; this is a macro-driven move across risk assets. The transmission runs through global yields rather than Japan-specific fundamentals.

## What would break the thesis

If markets treat the print as transitory and yields fail to rise, the pressure on equities should fade quickly.
