About Inflation Rate YoY — Japan
DEFINITION
The Inflation Rate YoY (Year-over-Year) is a financial indicator that measures the percentage change in the overall price level of goods and services over a 12-month period. It is a key measure of inflation and is used by economists and policymakers to monitor the health of an economy and make informed decisions regarding monetary policy. A higher inflation rate can indicate a growing economy, but if it rises too quickly, it can lead to negative effects such as decreased purchasing power and higher interest rates. Conversely, a lower inflation rate can signal a slowing economy, but if it falls too low, it can lead to deflation and potential economic instability. The Inflation Rate YoY is an important tool for understanding and managing the impact of price changes on the economy.
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. Surprises against consensus typically move rates and currencies on release. Released monthly.
WHAT CHANGED THIS MONTH
Latest reading (Apr 2026): actual 1.4 %, consensus 1.8 %. Prior reading (Mar 2026): 1.5 %. Before that (Feb 2026): 1.3 %.
