Global public debt is elevated. It is projected to exceed US$100 trillion in 2024 and will rise over the medium term. This chapter shows that risks to the debt outlook are heavily tilted to the upside. In a severely adverse scenario, global debt is estimated to be nearly 20 percentage points of GDP higher three years ahead than the baseline projection, reaching 115 percent of GDP. Much larger fiscal adjustments than currently planned are required to stabilize (or reduce) debt with high probability. Now is an opportune time for rebuilding fiscal buffers and delaying is costly. Rebuilding fiscal buffers in a growth-friendly manner and strengthening fiscal governance is essential to ensure sustainable public finances and financial stability.
This paper describes the compilation of the Global Debt Database (GDD), a cutting-edge dataset covering private and public debt for virtually the entire world (190 countries) dating back to the 1950s. The GDD is the result of a multiyear investigative process that started with the October 2016 Fiscal Monitor, which pioneered the expansion of private debt series to a global sample. It differs from existing datasets in three major ways. First, it takes a fundamentally new approach to compiling historical data. Where most debt datasets either provide long series with a narrow and changing definition of debt or comprehensive debt concepts over a short period, the GDD adopts a multidimensional approach by offering multiple debt series with different coverages, thus ensuring consistency across time. Second, it more than doubles the cross-sectional dimension of existing private debt datasets. Finally, the integrity of the data has been checked through bilateral consultations with officials and IMF country desks of all countries in the sample, setting a higher data quality standard.
The report explores how fiscal policy can foster resilience by protecting households against large income and employment losses. Governments face increasingly difficult trade-offs in tackling the spikes in food and energy prices when policy buffers are largely exhausted after two years of pandemic. They should prioritize protecting vulnerable groups through targeted support while keeping a tight fiscal stance to help reduce inflation. Building fiscal buffers in normal times would allow governments to respond swiftly and flexibly during adversities. Several fiscal tools, such as job-retention schemes, have proven useful to preserve jobs and income for workers. Social safety nets should be made more readily scalable and better targeted, leveraging digital technologies. Exceptional support to firms should be reserved for severe situations and requires sound fiscal risk management.
Persistently high debt ratios in advanced economies and emerging fragilities in the developing world cast clouds on the global fiscal landscape. In advanced economies, with narrowing budget deficits, the average public debt ratio is expected to stabilize in 2013–14—but it will be at a historic peak. At the same time, fiscal vulnerabilities are on the rise in emerging market economies and low-income countries—on the back, in emerging market economies, of heightened financial volatility and downward revisions to potential growth, and in low-income countries, of possible shortfalls in commodity prices and aid. Strengthening fiscal balances and buttressing confidence thus remain at the top of the policy agenda. Against that backdrop, this issue explores whether and how tax reform can help strengthen public finances. Taxation is always a sensitive topic and is now more than ever at the center of policy debates around the world. Can countries tax more, better, more fairly? Results reported in this issue show that the scope to raise more revenue is limited in many advanced economies and, where tax ratios are already high, the bulk of the necessary adjustment will have to fall on spending. In emerging market economies and low-income countries, where the potential for raising revenue is often substantial, improving compliance remains a central challenge.
This report emphasizes the environmental, fiscal, economic, and administrative case for using carbon taxes, or similar pricing schemes such as emission trading systems, to implement climate mitigation strategies. It provides a quantitative framework for understanding their effects and trade-offs with other instruments and applies it to the largest advanced and emerging economies. Alternative approaches, like “feebates” to impose fees on high polluters and give rebates to cleaner energy users, can play an important role when higher energy prices are difficult politically. At the international level, the report calls for a carbon price floor arrangement among large emitters, designed flexibly to accommodate equity considerations and constraints on national policies. The report estimates the consequences of carbon pricing and redistribution of its revenues for inequality across households. Strategies for enhancing the political acceptability of carbon pricing are discussed, along with supporting measures to promote clean technology investments.
Public sector balance sheets provide the most comprehensive picture of public wealth. They bring together all the accumulated assets and liabilities that the government controls, including public corporations, natural resources, and pension liabilities. They thus account for the entirety of what the state owns and owes, offering a broader fiscal picture beyond debt and deficits. Most governments do not provide such transparency, thereby avoiding the additional scrutiny it brings. Better balance sheet management enables countries to increase revenues, reduce risks, and improve fiscal policymaking. There is some empirical evidence that financial markets are increasingly paying attention to the entire government balance sheet and that strong balance sheets enhance economic resilience. This issue of the Fiscal Monitor presents a new database that shows comprehensive estimates of public sector assets and liabilities for a broad sample of 31 countries, covering 61 percent of the global economy, and provides tools to analyze and manage public wealth. Estimates of public wealth reveal the full scale of public assets and liabilities. Assets are worth US$101 trillion or 219 percent of GDP in the sample. This includes 120 percent of GDP in public corporation assets. Also included are natural resources that average 110 percent of GDP among the large natural-resource-producing countries. Recognizing these assets does not negate the vulnerabilities associated with the standard measure of general government public debt, comprising 94 percent of GDP for these countries. This is only half of total public sector liabilities of 198 percent of GDP, which also includes 46 percent of GDP in already accrued pension liabilities. Once governments understand the size and nature of public assets, they can start managing them more effectively. Potential gains from better asset management are considerable. Revenue gains from nonfinancial public corporations and government financial assets alone could be as high as 3 percent of GDP a year, equivalent to annual corporate tax collections across advanced economies. In addition, considerable gains could be realized from government nonfinancial assets. Public assets are a significant resource, and how governments use and report on them matters, not just for financial reasons, but also in terms of improving service delivery and preventing the misuse of resources that often results from a lack of transparency.
Even as the global economic outlook is stabilizing, fiscal policy continues to struggle with legacies of high debt and deficits, while facing new challenges. Public finances risks are acute this year as over 80 economies and economic areas are holding elections, amid increased support for high government spending. Financing conditions remain challenging, while spending pressures to address structural challenges are becoming more pressing. Countries should boost long-term growth with a well-designed fiscal policy mix to promote innovation more broadly, including fundamental research, and facilitate technology diffusion. Durable fiscal consolidation efforts are needed to safeguard sustainable public finances and rebuild buffers.
Two main themes of the book are that (1) politics can distort optimal fiscal policy through elections and through political fragmentation, and (2) rules and institutions can attenuate the negative effects of this dynamic. The book has three parts: part 1 (9 chapters) outlines the problems; part 2 (6 chapters) outlines how institutions and fiscal rules can offer solutions; and part 3 (4 chapters) discusses how multilevel governance frameworks can help.
Addressing climate change will entail major challenges for economic growth, employment, inflation, and public finances. Mitigating the impact of global warming will yield benefits and costs that are yet to be quantified and defined for the global economy and for nations, workers, households, and companies. The Green Frontier: Assessing the Economic Implications of Climate Action offers research originally presented at a major conference at the Peterson Institute for International Economics in June 2023 in Washington, DC, organized to shed light on this still unexplored field of study and recommend policies for the future.
