Global government debt on course to hit 100% of GDP by 2029, IMF warns1 day ago7 min read1 comments

The International Monetary Fund has issued a stark warning that global government debt is on a trajectory to reach 100% of worldwide gross domestic product by 2029, a level not witnessed since the immediate aftermath of the Second World War. This sobering projection, detailed in the IMF's latest Fiscal Monitor report, underscores a rapid and largely unanticipated escalation in sovereign borrowing, a trend supercharged by the massive fiscal interventions deployed by governments to shield their citizens and prop up businesses during the Covid-19 pandemic.The numbers paint a troubling macroeconomic picture: the aggregate debt-to-GDP ratio, which had been climbing steadily in the preceding decade, experienced a dramatic surge as treasuries opened their coffers for unprecedented stimulus packages, wage support schemes, and corporate bailouts. This has created a precarious fiscal environment where the delicate balance between stimulating growth and maintaining debt sustainability has become exceedingly difficult to manage.For market watchers, this is reminiscent of the post-2008 financial crisis era, but on a significantly larger and more systemic scale. The implications are profound; elevated debt levels constrain a government's ability to respond to future economic shocks, whether they be another public health emergency, a climate-related disaster, or a geopolitical conflict that disrupts supply chains.Furthermore, servicing this mountain of debt requires substantial interest payments, which in turn divert public funds away from critical long-term investments in infrastructure, education, and healthcare, effectively mortgaging the future for present-day stability. Central banks, including the Federal Reserve and the European Central Bank, now find themselves in a policy bind—while they may need to keep interest rates higher for longer to combat persistent inflation, doing so directly increases the cost of servicing this vast public debt, potentially triggering a vicious cycle.The situation is particularly acute for the United Kingdom, which the IMF identifies as one of the G20 nations forecast to see its debt peak at an especially concerning level, raising questions about the fiscal room available for any incoming government. Analysts drawing parallels to historical precedents, such as the debt-laden 1970s, warn that without a credible medium-term consolidation plan combining measured fiscal tightening with pro-growth structural reforms, many advanced economies risk entering a period of secular stagnation. The looming specter of 100% debt-to-GDP is not just a symbolic red line but a tangible threshold beyond which economic flexibility diminishes and vulnerability to market sentiment intensifies, a reality that finance ministers and investors will be grappling with for the remainder of the decade.
