The Impact of Interest Rates on Economic Growth

Introduction to Interest Rates and Economic Growth

Interest rates are a critical component of monetary policy and have significant implications for economic growth. This article synthesizes findings from multiple research studies to explore how interest rates influence economic growth across different regions and economic conditions.

Negative Impact of High Interest Rates on Economic Growth

Transitory Economies

Research indicates that high real interest rates negatively impact economic growth in transitory economies. A study covering 38 countries from 1996 to 2015 found that high real interest rates hinder economic growth through various channels, including reduced local and foreign investments, lower human capital development, and increased political instability and corruption. The study suggests that lower interest rates are essential for these economies to sustain their transition and achieve higher growth rates.

ASEAN Countries

In ASEAN-5 countries (Malaysia, Indonesia, Thailand, Singapore, and the Philippines), a long-term analysis from 1995 to 2018 revealed a strong negative relationship between interest rates and economic growth. The study emphasizes that high interest rates increase capital and investment costs, thereby slowing down economic growth.

Romania

In Romania, short-term economic growth is negatively influenced by high interest rates. The study used an autoregressive distributed lag (ARDL) model to show that higher interest rates reduce economic growth, while favorable exchange rates can have a positive impact.

Jordan

A study on Jordan from 1990 to 2019 found that a 1% increase in the real interest rate leads to a 0.97% decrease in real economic growth. This significant negative effect underscores the importance of maintaining lower interest rates to foster economic growth.

Mixed and Context-Dependent Effects

European Business Climate

The impact of interest rates on economic growth can also be influenced by external factors such as the business climate in the Euro area. In Romania, while high interest rates negatively affect growth, the business climate in the Euro area has mixed effects, indicating that external economic conditions can modulate the impact of domestic interest rates.

Interest Rate Spread

The interest rate spread, which is the difference between lending and deposit rates, also plays a crucial role. A study covering 40 countries from 2001 to 2021 found that a higher interest rate spread positively impacts economic growth, highlighting the importance of the banking sector in supporting economic activities. However, in Ghana, a high interest rate spread was found to negatively impact long-term economic growth, suggesting that the effects can vary based on regional economic conditions.

Policy Implications

Expansionary Monetary Policy

Several studies recommend adopting an expansionary monetary policy to stimulate economic growth. Lowering interest rates can increase market liquidity, encourage investments, and create a favorable environment for economic activities. For instance, in Jordan, reducing loan interest rates is suggested to attract investments and revive the economy. Similarly, in Indonesia, lower interest rates are associated with increased investments and economic growth.

Macroeconomic Stability

Ensuring macroeconomic stability is crucial for sustainable economic growth. Policymakers should focus on maintaining stable inflation rates and fostering a conducive business environment to maximize the positive effects of lower interest rates on economic growth.

Conclusion

The relationship between interest rates and economic growth is complex and multifaceted. High interest rates generally have a negative impact on economic growth by increasing the cost of capital and reducing investments. However, the effects can vary based on regional economic conditions and external factors. Policymakers should consider adopting lower interest rates and ensuring macroeconomic stability to foster sustainable economic growth.
