Negative Interest Rate Policy

A Negative Interest Rate Policy (NIRP) is an unconventional tool where a central bank sets a key policy rate below zero. Instead of earning interest on money they leave with the central bank, commercial banks are effectively charged for it. The goal is to discourage banks from hoarding idle cash and nudge them to lend to businesses and households, reviving spending and investment when normal rate cuts have run out of room.

How it works

Under NIRP, the rate applied to banks' surplus reserves turns negative. Because keeping money parked now costs them, banks have an incentive to push it into loans or other assets. The policy is typically deployed during deflation or stubbornly weak growth, when inflation is too low and conventional easing has already brought rates close to zero. Economies such as the euro area and Japan ran negative policy rates for several years; Japan formally ended its negative-rate era only in 2024.

In India

India has never adopted a negative interest rate policy. The RBI's Monetary Policy Committee (MPC) sets the repo rate, and Indian policy rates have always stayed comfortably positive, reflecting an economy whose challenge is usually managing inflation rather than fighting deflation. India's official inflation target, set jointly by the government and RBI, is 4% CPI with a tolerance band, and the MPC's tools are conventional rate moves, the cash reserve ratio and liquidity operations.

Why it matters

Even without a domestic NIRP, the concept matters for Indian savers and investors. When major economies run negative or ultra-low rates, global capital often hunts for higher yields, and a chunk flows into Indian bonds and equities. That can lift Indian markets and strengthen the rupee.

For a mutual-fund investor, NIRP abroad illustrates a key lesson: interest rates and bond prices move inversely, and when global rates are extremely low, debt funds offshore deliver minuscule returns. India's positive-rate environment is one reason its debt and equity markets remain attractive to foreign investors. Understanding NIRP helps explain why foreign flows surge or reverse as global central banks change course.
