The link between microeconomic variables and infrastructure development is central in determining the pace and sustainability of national growth and development, especially in times of economic volatility. This study examines the impact of key microeconomic variables, such as interest rates, inflation, exchange rates, and employment levels, on infrastructure development in Nigeria. A sample size of 150 respondents, comprising experts in the financial sector, policymakers, professionals in the construction industry, and economists, were selected to provide a comprehensive view on the subject. Methods used for data collection included a mix of surveys, interviews, and analysis of basic economic indicators. The study employs multiple regression analysis to assess the relationship between these variables and infrastructure outcomes, while qualitative data, on the other hand, was analyzed using thematic analysis methods. This involves identifying, analyzing, and reporting patterns (themes) within the data. Findings reveals a significant correlation between microeconomic instability, such as high inflation and fluctuating exchange rates, and delays or cost overruns in infrastructure project development. Conclusively, the study highlights the need for adaptive economic policies that consider microeconomic uncertainties to foster sustainable infrastructure development. The results provide a practicable insights for policymakers and investors aiming to mitigate the adverse effects of economic uncertainty on infrastructure development initiatives.
