What Is Negative Interest Rate Policy?
A negative interest rate policy (NIRP) is an unconventional monetary policy tool where a central bank sets its benchmark interest rates below zero. This means that commercial banks holding reserves with the central bank are charged a fee for those deposits, rather than earning interest. The primary goal of a negative interest rate policy is to encourage commercial banks to lend excess liquidity into the economy rather than holding it at the central bank, thereby stimulating economic growth and boosting inflation.
History and Origin
While the concept of negative interest rates has been discussed in economic theory for decades, its practical application by major central banks is a relatively recent phenomenon. Several European central banks, including those in Denmark, Sweden, and Switzerland, experimented with negative interest rate policies prior to the European Central Bank (ECB). However, it was the ECB's decision in June 2014 to cut its deposit facility rate to -0.10% that marked a significant milestone, as it was the first major central bank to adopt such a policy10, 11, 12. This move was implemented to counter persistently low inflation and weak economic activity across the eurozone, aiming to compel banks to increase lending to businesses and households8, 9.
Key Takeaways
- A negative interest rate policy (NIRP) involves a central bank charging commercial banks for holding excess reserves.
- The primary objective of NIRP is to stimulate lending, boost inflation, and spur economic activity, especially during periods of low growth or deflationary pressures.
- NIRP aims to de-incentivize hoarding cash and encourage investment and spending.
- Potential side effects include reduced bank profitability and challenges for savers.
Interpreting the Negative Interest Rate Policy
A negative interest rate policy signifies that monetary authorities are employing aggressive measures to combat economic stagnation or the threat of deflation. When the central bank sets a negative rate, it effectively imposes a cost on holding idle funds, signaling a strong desire for capital to flow into productive investments. This encourages banks to deploy their reserves by extending credit, purchasing assets, or reducing their liabilities, rather than incurring charges for holding them at the central bank. The interpretation is that the central bank believes conventional tools are insufficient and that a more forceful push is needed to achieve its mandates, often price stability and maximum employment.
Hypothetical Example
Imagine a country, "Economia," is experiencing prolonged low inflation and sluggish economic growth. The central bank of Economia, after exhausting conventional tools like lowering the benchmark interest rate to near zero, decides to implement a negative interest rate policy. It sets the deposit rate for commercial banks at -0.5%.
Before NIRP, commercial banks might hold significant excess reserves at the central bank, earning a negligible positive or zero interest. With the implementation of the negative interest rate policy, for every €100 million a commercial bank holds in excess reserves at the central bank, it now pays €500,000 annually. This direct cost incentivizes the bank to find more profitable uses for its money. It might decide to offer more favorable loan terms to businesses for expansion projects, extend mortgages to consumers at lower rates, or invest in government bond yields. The goal is to get this money circulating in the real economy, increasing aggregate demand and hopefully pushing inflation towards the central bank's target.
Practical Applications
Negative interest rate policy has been implemented by several central banks globally, particularly in developed economies facing low inflation or the threat of deflation, and slow economic growth. Countries like Switzerland, Denmark, Sweden, Japan, and the Eurozone have adopted NIRP at various times.
For instance, the European Central Bank (ECB) has utilized a negative interest rate policy as part of its toolkit to stimulate the eurozone economy. Over the past year, the ECB made several interest rate cuts to bring down borrowing costs and support growth, with their rates now back at the 2% target after easing inflation.

Central banks also hope that lower interest rates translate into weaker currency exchange rates, which can make exports cheaper and further stimulate the economy.
Limitations and Criticisms
Despite its intended stimulus, a negative interest rate policy faces several limitations and criticisms. One significant concern is the potential impact on bank profitability. While the policy aims to encourage lending, banks often find it difficult to pass negative rates onto retail depositors. This reluctance stems from the fear of alienating customers who might withdraw funds and hold physical cash, effectively disintermediating the banking system. As4, 5 a result, banks' net interest margins—the difference between the interest they earn on loans and the interest they pay on deposits—can shrink, potentially reducing their capacity or willingness to lend, which contradicts the policy's objective.
Criti3cs also point to the potential for distorting financial markets and household behavior. Prolonged periods of negative rates might encourage excessive risk-taking as investors "reach for yield" in a low-return environment. For savers, negative rates can erode the value of their savings, potentially leading to reduced future consumption and impacting long-term financial planning. Some argue that the effectiveness of negative interest rate policy diminishes over time, and that its stimulative effect might be less potent than anticipated, with adverse consequences for bank balance sheets and the overall financial system. Furthe2rmore, while negative interest rates might offer some stimulus, they are not a panacea and may need to be complemented by other measures, such as expansionary fiscal policy, to achieve desired economic outcomes.
Ne1gative Interest Rate Policy vs. Quantitative Easing
Negative interest rate policy (NIRP) and quantitative easing (QE) are both unconventional monetary policy tools employed by central banks to stimulate an economy when conventional interest rate cuts are no longer effective, typically when the nominal interest rate approaches zero. However, their mechanisms differ fundamentally.
NIRP directly targets the interest rate paid on commercial banks' excess reserves held at the central bank, pushing it below zero. The aim is to make it costly for banks to hold idle money, thus incentivizing them to lend these funds into the real economy. It's a direct charge on reserves.
In contrast, quantitative easing involves the central bank buying large quantities of government bonds or other financial assets from commercial banks and other financial institutions. This action injects new money into the financial system, increasing banks' reserves and liquidity. The goal of QE is to lower long-term bond yields, increase the money supply, and encourage lending and investment by making credit more accessible and cheaper. While both policies aim to boost economic activity and inflation, NIRP works by imposing a penalty on holding reserves, whereas QE works by directly increasing the quantity of reserves and lowering long-term rates through asset purchases.
FAQs
Why would a central bank implement a negative interest rate policy?
A central bank typically implements a negative interest rate policy to combat very low inflation or deflation and stimulate a stagnant economy. By charging commercial banks for holding excess reserves, the central bank aims to force them to lend money more freely, encouraging spending and investment across the economy.
How does a negative interest rate policy affect savers?
For savers, a negative interest rate policy can be challenging. While retail banks rarely pass on negative rates directly to small depositors, the overall interest rate environment becomes very low. This means that savings accounts and other low-risk investments may offer little to no return, and in some cases, real returns (after inflation) could be negative. This can incentivize individuals to seek higher-yielding, potentially riskier, investments.
Do negative interest rates mean I have to pay to keep money in my bank account?
Generally, for individual depositors, banks are highly reluctant to apply negative interest rates directly to checking or savings accounts. This is largely because individuals could simply withdraw cash if they were charged. Instead, the costs imposed by a negative interest rate policy are typically absorbed by banks, impacting their profitability, or potentially passed on to corporate clients or through other fees.
What are the main risks associated with a negative interest rate policy?
The main risks include reduced bank profitability, as banks struggle to pass on negative rates to depositors, potentially dampening their incentive to lend. There's also a risk of market distortions, where investors take on excessive risk in search of yield, and concerns about the long-term impact on financial stability and the functioning of money markets.
Has a negative interest rate policy been successful?
The success of a negative interest rate policy is debated among economists. Proponents argue it has provided some stimulus and prevented deeper recession or deflation in certain economies. Critics contend that its benefits are limited, particularly over the long run, and that it can harm bank profitability and distort financial markets without achieving substantial economic growth or inflation targets.
