Understanding Inflation Rate MoM — a simple guide
What it measures
The change in the consumer price index compared with the previous month.
How it is calculated
(CPI this month ÷ CPI last month − 1) × 100.
If the CPI index rose from 200.0 to 200.6, monthly inflation is 0.3%.
A high monthly reading shows prices are rising quickly right now.
A negative reading means prices fell compared with last month.
Why it matters for the economy and markets
Monthly changes show the latest momentum in prices, months before it fully shows up in the year-on-year rate.
How to read it
Monthly numbers are small: 0.2% a month is about 2.4% a year. Some months are always higher (festivals, harvest effects), so compare the same month across years.
What to look at alongside it
Year-on-year inflation and core inflation.
Key terms
- MoM
- Month-on-month: compared with the previous month.
