This research intends to investigate the connection between interest rates and various economic factors, including inflation, investment, savings, and consumption. It will analyze how these variables are influenced by interest rates, beginning with their effect on inflation; an increase in interest rates is demonstrated to lower inflation by diminishing aggregate demand, while also considering how anticipated inflation influences the correlation between nominal and real interest rates. Moreover, the research emphasizes the link between interest rates and investment, suggesting that elevated interest rates lead to a decrease in both investment volume and economic growth due to higher borrowing expenses, while simultaneously promoting savings and enhancing the resources available for investment. The study also examines the repercussions of interest rates on savings and income, pointing out that the influence of interest rates on savings volume is relatively minor in comparison to income levels. Lastly, it evaluates how interest rates impact consumption, revealing that rising interest rates result in a decline in private consumption by fostering savings and lowering the demand for money. Utilizing a descriptive analytical approach, the study encompasses a review of economic literature, data analysis through technical instruments like statistical software, and the implementation of sophisticated statistical models to derive insights and recommendations from the results obtained. It advocates for the formulation of monetary policies that strike a balance between encouraging investment and managing inflation, as well as the enhancement of savings strategies that promote sustainable economic growth. Additionally, the study emphasizes the importance of employing digital technologies for the collection and analysis of economic data, alongside the adoption of advanced technological solutions to assess the impacts of interest rate changes on various facets of the economy, ensuring overall economic stability.
