The Reserve Bank of India (RBI) is under scrutiny because its model for predicting inflation has been consistently wrong this year. Economists are pointing out that the central bank keeps overestimating how high prices will rise.
The biggest mistake was in the first three months of the year, where the RBI’s forecast was off by a huge 0.7 percentage points. This was the largest gap in almost six years. Even in later quarters, the estimates have been higher than the actual inflation.
This forecasting error has led the RBI to take a “hawkish” (tougher) stance on policy, meaning it has been hesitant to lower interest rates. Economists argue that this might have been unnecessary, making the policy unintentionally restrictive at a time when the economy needed a boost. The RBI’s mandate is to keep inflation at 4%. However, the current inflation for the fiscal year through March is expected to be as low as 2% to 2.2%.
The main reason for the incorrect forecasts is a sharp and unexpected drop in food prices. Strong harvests and better supply chain management have lowered the cost of food, which makes up almost half of the consumer price index. For example, food prices dropped by a record 5.02% in October compared to the previous year.
Experts suggest that central banks sometimes make conservative forecasts that “embed policy intentions” rather than just pure predictions. But when inflation repeatedly comes in lower than expected, it can hurt the central bank’s credibility.
The RBI has acknowledged the volatility in food prices and is working on refining its forecasting model.It is also noted that the index used to measure consumer prices hasn’t been updated in over a decade, which also adds to the difficulty of making accurate predictions.
