Zero Interest Rate Policy

What Is Zero Interest Rate Policy (ZIRP)?

Zero interest rate policy (ZIRP) is a macroeconomic approach in which a country's central bank sets very low nominal interest rates, often at zero percent for its short-term benchmark. When using this unconventional monetary policy tool, there are often prevailing economic conditions like deflation and sluggish economic development.

The zero-interest rate policy (ZIRP) represents a shift in monetary policy. ZIRP's main goal is to promote borrowing and investment to bolster economic expansion. It aims to boost economic activity by promoting low-cost borrowing and increased availability of low-cost credit for businesses and consumers. It promotes lending and addresses liquidity issues in the financial markets.

• Zero interest rate policy (ZIRP) is a monetary policy technique in which the central bank sets extremely low nominal interest rates, frequently at 0 percent, for its short-term benchmark.
• ZIRP promotes investment and increases the availability of credit. In the long run, low-interest rates can help stimulate and strengthen an economy facing challenges.
• While ZIRP boosts central bank commitment, promotes risky asset investment, and stimulates economic growth, it requires significant changes to the financial system, can be expensive and inconvenient, and may negatively impact retirees and pension schemes.

Zero Interest Rate Policy Explained 

Zero Interest Rate Policy (ZIRP) is a monetary policy strategy in which a nation's central bank sets the benchmark interest rate at or close to 0 percent. ZIRP seeks to promote investment, borrowing, and economic growth by discouraging saving and promoting spending through exceptionally low borrowing costs. ZIRP is used to boost economic activity when there are deflationary pressures or times of economic downturn. It encourages companies and people to spend, invest, and borrow by lowering borrowing costs, which can increase investment, consumption, and total economic growth. It also supports lending and helps to alleviate liquidity issues in the financial markets.

The economy is impacted by central bank interest rates, which offer investors a benchmark risk-free rate of return. In addition to providing an opportunity for possible investments, low-interest rates enable borrowing larger amounts of money for the same cost. A zero interest rate stimulates more investment and frees up credit by encouraging investors to pursue riskier investments. Low-interest rates have the potential to stimulate and revive an economy that is experiencing difficulties in the long run. Thus, ZIRP aims to stimulate economic expansion and boost inflation by disincentivizing cash hoarding and incentivizing lending, spending, and investment.

The Zero Lower Bound Problem (ZLB) is a situation in which rates cannot be lowered any further because it is a crucial turning point in monetary policy. It describes a scenario with a liquidity trap, and the short-term nominal interest rate is either 0 or slightly above zero. This liquidity trap limits the central bank's ability to promote economic expansion. When ZIRP was implemented, it is believed that central bankers had exhausted all other avenues of monetary policy control.

Examples 

Let us look into a few examples to understand the concept better

Example #1

Suppose XYZ country is experiencing a deep recession marked by slow growth and low inflation. The central bank chooses to put ZIRP into effect to boost economic activity. The benchmark interest rate setting aims to stimulate consumer spending, promote borrowing and investment, and bring the economy back to life. The central bank hopes to ease some financial pressure and provide these companies some breathing room by enacting ZIRP. This may allow them to carry on with business as usual, keep employees and staff, and stimulate the economy, all of which will eventually aid in stabilizing the economy.

Example #2

The Bank of Japan (BOJ) instituted a policy of negative interest rates to incentivize banks to remove surplus reserves from the central bank and enhance lending to consumers and corporations. However, despite the vertical IS(Investment-Saving) curve, loans to the business sector did not rise.

The BOJ set a 2% inflation target in April 2013 to combat deflation and achieve long-term economic growth. However, because of the decline in global oil prices, it was unable to meet this goal and had to take further action. As a result, the BOJ decided to implement a negative interest rate policy in February 2016 and greatly expanded the money supply by buying long-term Japanese government bonds (JGB).

Before this, the BOJ had mostly bought short-term government bonds, which caused the yield curve of JGBs (Japanese Government Bonds) to flatten. On the one hand, the negative yields on short-term bonds and even the negative interest rates on long-term government bonds for up to 15 years caused banks to lower their holdings of government bonds.

Several factors contribute to this, including an aging population, a declining labor force, low female employment participation, a conservative financial system, less effective local governments, a lack of technical advancement, slow growth in small and medium-sized entrepreneurs, and the emergence of startup companies. However, the IS curve is vertical because of the low marginal productivity of capital and the declining interest in investment by the corporate sector.

According to the paper, Japan's current monetary policy—particularly its negative interest rate policy—is insufficient to address the country's persistent deflation issue and enable it to emerge sustainably from its protracted recession.

Pros And Cons 

Some of the pros and cons of the zero rate policy are the following:

Pros

• The unveiling of a fresh stimulus program would strengthen the central bank's dedication to the inflation objective.
• In a perfect world, it would promote investment in riskier and higher-yielding assets like real estate, commodities, junk bonds, and stocks, raising asset values and creating a "wealth effect" to enhance consumption and economic growth.

Cons

• There are difficulties in putting such a system into place. Significant changes to the financial and legal systems would be necessary.
• Large sums of cash are expensive (storage and insurance fees, for example) and inconvenient.
• Although these policies increase demand, they are insufficient to compensate for the lost policy space (space for making better economic decisions) in low-interest rates.
• Current retirees who depend on interest income to support themselves are forced to cut back on their spending due to the extremely low interest rate environment. The low-interest rate environment severely impacts pension schemes and individual retirement planning.
• A temporary zero-interest rate policy might be effective soon, but shifting public opinion may cause counterproductive actions.

The approach's advantages and disadvantages vary depending on the nation. It should be weighed against alternative ideas, such as raising inflation targets to expand monetary policy options during a low-interest rate period. For example, the Fed's zero-interest rate policy will depend on U.S. economic conditions, and Japan's zero-interest rate policy depends on Japan’s economic conditions.
