Monetary policy can only hope to address future inflation, not today's: RBI Deputy Governor | Mint – Mint

  • The RBI Deputy Governor said forecasts can be made into the future, but they are based on backward-looking information from one to three months ago

RBI Deputy Governor Michael Debabrata Patra has said monetary policy can only hope to address future inflation, not today’s inflation. Speaking at the 9th SBI Banking and Economics Conclave in Mumbai on Thursday, he said monetary policy is by its nature a technical area of economic policy-making and it has to be forward-looking.
The  RBI Dy Governor said that preparing monetary policy is a challenging task, especially in a volatile market like the current one where there are lagged data that are also reviewed frequently.
RBI’s next monetary policy meeting is scheduled to take place in the first week of December. Patra said the RBI MPC meeting will do deliberation on inflation data for October and growth data for July-September.
“Today, inflation is at levels not seen in four decades, impervious to aggressive and front-loaded monetary policy tightening across the world. The existential question being asked is whether the world is permanently shifting from a low-inflation environment to a high-inflation one. The time has come to review the objectives of monetary policy,” he said.
The RBI Deputy Governor said forecasts can be made into the future, but they are based on backward-looking information from one to three months ago. And they can be thrown off course by unanticipated shocks that hit them in the future, he said, adding that goal variables were moving over time and so monetary policymakers have to take into account not their known positions but their uncertain future trajectory.
“Then they have to shoot forward – getting the angle right is crucial to taking the shot,” Patra added.
In this challenging situation, he said, monetary policymakers sift through an ocean of information – high-frequency indicators; forward-looking surveys; expectations of market participants, professional forecasters, and analysts; econometric models; sentiment analysis based on artificial intelligence and machine learning techniques; all as a part of trying to guess the likely future path of the goal variables.
The Deputy Governor also said there was a growing body of work on the new approach of textual analysis that is challenging economists and providing new insights into monetary policy decision-making.
In the RBI, he said, the central bank was conducting studies on monetary policy communication by text processing the minutes of the MPC at multiple levels using text mining techniques.
“The preliminary findings are that the length of the minutes was higher during 2019 – presumably reflecting deliberations on rate cuts -, in periods following different waves of COVID-19 and after the start of the war in Ukraine,” he said, adding that the minutes were fairly readable and readability levels were consistently maintained. “In the period following the war in Ukraine, sentiment deteriorated among both internal and external members.”
RBI has been increasing the repo rate since May 2022 to tame multi-year high inflation. The  rates has been cumulatively raised by 190 basis points to 5.9% since May this year.
Inflation has stayed above RBI’s upper tolerance limit for the tenth consecutive month. In October, the consumer price index eased to 6.77% but stays above RBI’s limit. Inflation had jumped to a five-month high in September to 7.41%.
