In exploring the intricate dynamics of public debt and its implications for economic growth, the study adeptly recognizes the universal significance of debt within fiscal accounts across diverse nations. The notion of a tipping point, where excessive debt becomes detrimental to economic well-being, adds a crucial layer to the understanding of this complex relationship. The Philippines serves as a compelling case study, offering insights into the pressing concerns surrounding escalating debt and its potential ramifications on the nation's economic landscape. The meticulous identification of four macroeconomic indicators and their subsequent regression analysis, yielding a substantial coefficient of determination at 91.42%, underscores the profound impact of these variables on public debt. Notably, the discernment that Gross Capital Formation (GCF) and Foreign Direct Investment (FDI) hold significant correlations with public debt, leading to the rejection of null hypotheses, provides a nuanced perspective. The positive relationship between GCF and public debt introduces a paradox, contrasted by FDI's negative coefficient, positioning it as a promising avenue for debt reduction. The study's emphasis on the substantial decrease in public debt with an increase in FDI, along with the insignificance of inflation rate and trade balance in this context, underscores the potential policy implications. The study not only uncovers intricate relationships but also subtly advocates for strategic reliance on FDI as a measure to alleviate the burden of public debt, offering a valuable contribution to the ongoing discourse on economic management and fiscal policy.
