Economic Growth Under Pressure: The Role of Inflation, Interest Rate, and Tax in Pakistan

Abstract

Background of the Study

Economic growth is one of the most significant measures of a country's growth and prosperity. It is a measure of the growth of goods and services, the improvement in the standard of living and the overall economic stability. Many macro-economic variables, such as inflation, interest rates, taxes, etc., play an important role in economic growth in developing countries like Pakistan.

Inflation impacts the buying power of consumers and generates uncertainty in the economy while interest rates have an impact on things like borrowing, investment and consumer purchase. Likewise, taxes are a key component of government income and influence of business activity and investment opportunities. These factors can interact in such a way as to affect economic performance and long-term growth.

Over the years, Pakistan has witnessed significant changes in policy rates, inflation rates, and tax rates, which have caused difficulties for policy makers, businesses and investors. The understanding of the impact of these on economic growth is crucial for developing sound fiscal and monetary policies. Hence, the present study aims to investigate the impact of inflation, interest rate and tax on the economic growth of Pakistan and the combined effect of all these three factors with respect to economic stability and development.

The long-term growth and success of modern economies depend on macroeconomic parameters including taxation, interest rates and inflation. These have been very volatile in Pakistan in the past, creating issues for investors and government. Therefore, interest rates influence borrowing and saving choices, taxes determine the amount of tax revenues and the allocation of resources and inflation influences purchasing power and overall economic well-being.

A study published in PLOS One, by Stylianou et al. (2024), found that inflation in Pakistan is tightly coupled with monetary variables such as money supply, which highlights the occurrence of structural and policy-driven issues that often result in macroeconomic instability. The study also highlights the dynamic interplay of these dimensions and the influence on growth patterns over time rather than their independence.

Tax, interest rates and inflation plays an important role in the dynamics of the investment and growth of the economy. Stylianou et al. (2024) argue that inflation has an intricate relationship with economic growth, with high inflation rates inhibiting investment and instilling uncertainty, while economy-friendly inflation rates can stimulate economic growth.

Likewise, interest rates are directly related to the cost of borrowing. A business has to pay more when interest rates are high, thereby reducing investment and slowing the economy. According to Rana et al. (2025) Interest rate and inflation are interrelated and both affect economic growth and stability of developing countries such as Pakistan.

Another important factor is taxation. Even in the cases of Pakistan, studies reveal that high tax rates will deter economic activity and will reduce growth potential if taxes are required to generate government revenue (Shafiq et al., 2022). Also, direct and indirect taxes have different impacts on the economy: indirect taxes can often have a larger effect on GDP.

It is important to understand the relationship between monetary policy (inflation and interest rate management) and fiscal policy (taxation and government spending) for economic stability. The fiscal policies such as tax income and fiscal deficit are found to influence the inflation and overall economic performance, especially in emerging countries by Junejo et al. (2021).

Furthermore, monetary policy tools like interest rates are used to control the economy and bring down the inflation rate. Inflation and interest rates are short-termly related with economic growth, so there is a need for policy coordination for stability (Hayat et al., 2021). The interaction points out the importance of combining both fiscal and monetary strategies to achieve economic stability. A composite score of the two impacts on investment and economic activity.

The impact of a combination of taxation, interest rates and inflation can have an impact on investment decisions and economic returns. The implication of the reverse is that higher interest rates mean that capital would be more expensive, which may limit the growth of companies; and inflation would mean that the real returns on investments would decline. At the same time taxation policies also influence profitability and incentives for investment.

Research in Pakistan shows that there is an overall long-term relationship between capital formation, saving and inflation. Ibrar et al. (2024), suggests that these factors operate together to affect the investment pattern of the economy. Moreover, analysis shows that mismanagement of tax revenue and inflation can be negative to economic development, which is the reason for the need of a balanced tax and inflation policy. These challenges need to be met, to sustain the economic stability and steady progress forward.
