Inflation surge due to unfavourable base effect
- The Reserve Bank of India (RBI) has said that the increase in inflation in December 2021 was entirely due to unfavourable base effects despite month-on-month decline in prices.
Base Effect
- The base effect is the effect that choosing a different reference point for a comparison between two data points can have on the result of the comparison.
- It refers to the impact of an increase in the price level (i.e. previous year’s inflation) over the corresponding rise in price levels in the current year (i.e., current inflation).
- For instance, a “3% year-over-year increase in May” after an already elevated price level in May of last year would imply higher price levels than a “3% year-over-year increase” after a depressed price level in May of last year.
