Background of the Global Increase in National Debt Post-Pandemic Since the pandemic, the global economy has faced unprecedented challenges. As governments worldwide injected massive fiscal resources to combat COVID-19, national debt soared to historic levels, and the burden is now becoming a stark reality. Professor Carmen Reinhart, former Chief Economist of the World Bank and a renowned economist, recently issued a strong warning about this situation in an article for Project Syndicate. She pointed out that the national debt and fiscal deficits faced by countries post-pandemic pose a severe threat to global economic stability, and that policy options for restoring fiscal soundness are extremely limited amidst the dual challenges of high inflation and high interest rates. According to Professor Reinhart's analysis, most countries, both developed and developing, undertook unprecedented levels of fiscal spending during the pandemic response. While this was an unavoidable choice to prevent economic collapse and protect livelihoods, the accumulated debt is now hindering governments worldwide. A particular concern is the sharp rise in the interest burden on national debt, as the low-interest rate environment during the pandemic has ended and central banks globally have rapidly increased interest rates to curb inflation. This significantly raises the proportion of interest payments in government budgets, eroding resources that could be allocated to essential public services such as education, healthcare, and infrastructure. Professor Reinhart argues that to restore fiscal soundness, governments must consider increasing revenue, cutting spending, and, in some cases, even debt restructuring. However, all these options entail substantial political costs. Increasing revenue implies tax hikes, which can provoke strong public backlash. Spending cuts, too, are likely to lead to social conflict by reducing welfare benefits or public services. Debt restructuring can result in a downgrade of national credit ratings and financial market turmoil. Therefore, policymakers face a dilemma in finding a balance among these difficult choices. Professor Reinhart particularly emphasizes historical lessons. She analyzes past fiscal crises, demonstrating how complex and unpredictable the fiscal stabilization process can be after a pandemic. History is replete with examples showing how quickly fiscal imbalances can escalate into full-blown economic crises, such as the Latin American debt crisis in the 1980s, the Asian financial crisis in the 1990s, and the European fiscal crisis after the 2008 global financial crisis. These historical experiences offer crucial insights into the current situation. A fiscal crisis is not merely a government problem; it can heighten financial market instability, dampen private sector investment and consumption, and ultimately lead to a vicious cycle that undermines overall economic growth. Professor Reinhart also warns that the potential for fiscal crises exists in both developed and developing countries. Developed nations face large absolute debt levels and persistent pressure from increasing welfare spending due to aging populations, while developing countries are burdened by growing external debt with limited fiscal capacity. Developing countries, in particular, are exposed to the risk of default as a strong dollar and rising interest rates sharply increase their external debt repayment burden. If these risks materialize, global financial market volatility could expand, triggering a chain reaction that negatively impacts even developed economies. Korea's Economy and the Global Fiscal Crisis Link So, how safe is South Korea from the current global fiscal crisis? While Professor Reinhart's article does not directly mention Korea, applying her analytical framework to the Korean context reveals several concerning implications. South Korea also injected a significant amount of fiscal resources during the pandemic response, and its national debt-to-GDP ratio is rapidly rising. Of course, Korea's national debt ratio is relatively lower compared to other major developed countries. However, what matters more than the absolute figure is the speed and direction of change. Considering the structural challenges facing the Korean economy, concerns about fiscal soundness are growing. Rapid aging and the world's lowest birth rate foreshadow a dual pressure of a shrinking working-age population and a surge in welfare expenditures. Aging-related expenditures, such as pensions, healthcare, and long-term care, are structurally bound to increase, placing continuous strain on public finances. Simultaneously, the decline in the working-age population is expected to weaken the tax base, exacerbating difficulties on the revenue side. These demographic changes are not short-term issues, making long-term fiscal planning imperative. Furthermore, Korea has an export-oriented open economic structure, making it highly sensitive to ch
