India Sees Natural Rate of Interest Rise to 1.4-1.9% in Q4FY24: RBI Study

India's natural rate of interest rose to 1.4-1.9% in the quarter ending March 2024, up from 0.8-1.0% in Q3 of 2021-22, according to an RBI article released on Thursday. The natural rate is influenced by factors affecting long-term saving and investment behaviours. Specifically, elements that decrease saving or boost investment elevate the natural rate.

Monetary policy differences across regions have sparked renewed discussions about the natural rate of interest. Updating India's natural rate estimates with post-pandemic data reveals an upward shift due to potential output growth. For Q4:2023-24, the lower bound estimate is 1.4%, within a broader range extending to 1.9%, compared to 0.8-1.0% for Q3:2021-22.

Impact of Demographics on Natural Rate

India's demographic structure, featuring a large youth population and an expanding working-age group, positively impacts the natural rate of interest. This demographic trend encourages higher saving and investment, as well as financial commitments for education, housing, marriage, and retirement.

The article titled "Updating Estimates of the Natural Rate of Interest for India with Post-Pandemic Evidence" was authored by Harendra Kumar Behera, a senior official in the RBI's Department of Economic and Policy Research (DEPR). It emphasised the necessity of understanding and accurately measuring the natural rate with regular updates.

Long-Term Effects of Monetary Policy

Although traditional macroeconomic theory suggests that monetary policy is neutral in the long run and only affects real variables temporarily, recent studies indicate that monetary policy can have enduring effects on real variables. The natural rate could also fluctuate due to long-term influences of monetary policy.

Policymakers and financial market participants must continually refine their methods for estimating the natural rate to ensure it remains a dependable guide for policies aimed at sustainable economic growth and stability. "Abstracting from the wider credible bands around our current estimates in the aftermath of the pandemic, the importance of understanding the natural rate and measuring it accurately with regular updates cannot be overemphasised," stated the article.

The central bank clarified that the views expressed in the article are those of the authors and do not represent RBI's official stance.
