The relationship between budget deficits and interest rates
Year: 2025
Type: article
Abstract: The relationship between budget deficits and interest rates has been a central theme in macroeconomic discourse, influencing fiscal and monetary policy decisions worldwide. Classical economic theories suggest that rising budget deficits exert upward pressure on interest rates through the mechanism of crowding out private investment. However, empirical evidence on this relationship remains mixed and often context-dependent. Some studies suggest that deficits drive interest rates higher, while others emphasize mitigating factors such as global capital flows and accommodative monetary policy. This paper explores multiple theoretical perspectives, including the crowding-out hypothesis, Ricardian equivalence, the portfolio balance model, and the interaction between fiscal expectations and monetary policy. Empirical evidence from cross-country studies, time-series analyses, and recent fiscal expansions during the COVID-19 pandemic is synthesized to present a nuanced view. Special attention is given to emerging markets, where the relationship tends to be more pronounced due to higher risk premia. Additionally, the role of debt sustainability and investor confidence is emphasized. By integrating theoretical insights with empirical findings, the study offers a comprehensive understanding of the conditions under which budget deficits affect interest rates and outlines policy recommendations for managing fiscal deficits effectively without destabilizing financial markets.
