What Does a Negative Interest Rate Mean?

A negative interest rate means that a central bank charges commercial banks for holding excess reserves, and in theory, lenders pay borrowers for the privilege of taking their money. It is an unconventional monetary policy tool used to stimulate a sluggish economy by encouraging lending and spending rather than hoarding cash.

How Negative Interest Rates Work

When a central bank sets a negative rate, it inverts the normal flow of money. Instead of earning interest on deposits, banks may face a fee for parking funds at the central bank. To avoid that cost, banks are incentivized to lend more aggressively to businesses and consumers. The goal is to boost economic activity by making borrowing cheaper and saving less attractive.

Why Central Banks Use Negative Rates

Central banks turn to negative rates when traditional tools, like lowering rates to zero, have been exhausted. The policy aims to:

• Stimulate inflation when it is running persistently below target.
• Encourage banks to lend rather than sit on excess capital.
• Weaken the national currency to support exports.
• Drive investors into riskier assets like stocks and corporate bonds.

Impact on Savers and Investors

Negative rates can erode returns for ordinary savers. Bank deposit rates may fall below zero in theory, though most banks absorb the cost to avoid passing charges to retail customers. For investors, negative rates push bond yields down and can compress yields across the spectrum, forcing a search for positive returns in equities or alternative assets. The policy also raises the risk of asset bubbles by pushing capital into overvalued markets.

Real-World Examples

Several major economies have experimented with negative rates. The European Central Bank and the Bank of Japan both adopted negative policy rates during periods of prolonged low inflation and slow growth. These experiences showed mixed results: lending did increase in some cases, but the transmission mechanism proved imperfect, and the policy created headaches for bank profitability.
