    What Has Been the Impact of COVID-19 on Debt? Turning a Wave into a Tsunami
    (World Bank, Washington, DC, 2021-11) Kose, M. Ayhan ; Nagle, Peter ; Ohnsorge, Franziska ; Sugawara, Naotaka
    This paper presents a comprehensive analysis of the impact of COVID-19 on debt, puts recent debt developments and prospects in historical context, and analyzes new policy challenges associated with debt resolution. The paper reports three main results. First, even before the pandemic, a rapid buildup of debt in emerging market and developing economies—dubbed the “fourth wave” of debt—had been underway. Because of the sharp increase in debt during the pandemic-induced global recession of 2020, the fourth wave of debt has turned into a tsunami and become even more dangerous. Second, five years after past global recessions, global government debt continued to increase. In light of this historical record, and given large financing gaps and significant investment needs in many countries, debt levels will likely continue to rise in the near future. Third, debt resolution has become more complicated because of a highly fragmented creditor base, a lack of transparency in debt reporting, and a legacy stock of government debt without collective action clauses. National policy makers and the global community need to act rapidly and forcefully ensure that the fourth wave does not end with a string of debt crises in emerging market and developing economies as earlier debt waves did.

    Debt and Financial Crises
    (World Bank, Washington, DC, 2020-01) Koh, Wee Chian ; Kose, M. Ayhan ; Nagle, Peter S. ; Ohnsorge, Franziska L. ; Sugawara, Naotaka
    Emerging market and developing economies have experienced recurrent episodes of rapid debt accumulation over the past fifty years. This paper examines the consequences of debt accumulation using a three-pronged approach: an event study of debt accumulation episodes in 100 emerging market and developing economies since 1970; a series of econometric models examining the linkages between debt and the probability of financial crises; and a set of case studies of rapid debt buildup that ended in crises. The paper reports four main results. First, episodes of debt accumulation are common, with more than 500 episodes occurring since 1970. Second, around half of these episodes were associated with financial crises which typically had worse economic outcomes than those without crises -- after 8 years output per capita was typically 6-10 percent lower and investment 15-22 percent weaker in crisis episodes. Third, a rapid buildup of debt, whether public or private, increased the likelihood of a financial crisis, as did a larger share of short-term external debt, higher debt service cover, and lower reserves cover. Fourth, countries that experienced financial crises frequently employed combinations of unsustainable fiscal, monetary and financial sector policies, and often suffered from structural and institutional weaknesses.

    Can This Time Be Different? Policy Options in Times of Rising Debt
    (World Bank, Washington, DC, 2020-03) Kose, M. Ayhan ; Nagle, Peter S.O ; Ohnsorge, Franziska L. ; Sugawara, Naotaka
    Episodes of debt accumulation have been a recurrent feature of the global economy over the past fifty years. Since 2010, emerging and developing economies have experienced another wave of historically large and rapid debt accumulation. Similar past debt buildups have often ended in widespread financial crises in these economies. This paper examines the factors that are likely to determine the outcome of the most recent debt wave, and considers policy options to help reduce the likelihood that it ends again in widespread crises. It reports two main results. First, the rapid increase in debt has made emerging and developing economies more vulnerable to shifts in market sentiment, notwithstanding historically low global interest rates. Second, policy options are available to lower the likelihood of financial crises, and to help manage the adverse impacts of crises when they do occur. These include sound debt management, strong monetary and fiscal frameworks, and robust bank supervision and regulation. The post-crisis debt buildup has coincided with a period of subdued growth as well as the emergence of non-traditional creditors. As a result, policy priorities also need to ensure that debt is spent on productive purposes to improve growth prospects and that all debt-related transactions are transparently reported.

    A Decade After the Global Recession: Lessons and Challenges for Emerging and Developing Economies
    (Washington, DC: World Bank, 2021-03-18) Kose, M. Ayhan ; Ohnsorge, Franziska ; Kose, M. Ayhan ; Ohnsorge, Franziska ; Arteta, Carlos ; Celik, Sinem Kilic ; Ha, Jongrim ; Kasyanenko, Sergiy ; Koh, Wee Chian ; Lakatos, Csilla ; Ruch, Franz Ulrich ; Sugawara, Naotaka ; Taskin, Temel ; Terrones, Marco E. ; Ye, Lei Sandy ; Yu, Shu
    This year marks the tenth anniversary of the 2009 global recession. Most emerging market and developing economies weathered the global recession relatively well. However, following a short-lived initial rebound in activity in 2010, the global economy and, especially, emerging market and developing economies, have suffered a decade of weak growth despite unprecedented monetary policy accommodation and several rounds of fiscal stimulus in major economies. A Decade After the Global Recession provides the first comprehensive stock-taking of the decade since the global recession for emerging market and developing economies. It reviews the experience of emerging market and developing economies during and after the recession. Many of these economies have now become more vulnerable to economic shocks. The study discusses lessons from the global recession and policy options for these economies to strengthen growth and be prepared should another global downturn occur.

    Global Waves of Debt: Causes and Consequences
    (Washington, DC: World Bank, 2021-03-02) Kose, M. Ayhan ; Nagle, Peter ; Ohnsorge, Franziska ; Sugawara, Naotaka
    The global economy has experienced four waves of rapid debt accumulation over the past 50 years. The first three debt waves ended with financial crises in many emerging market and developing economies. During the current wave, which started in 2010, the increase in debt in these economies has already been larger, faster, and broader-based than in the previous three waves. Current low interest rates mitigate some of the risks associated with high debt. However, emerging market and developing economies are also confronted by weak growth prospects, mounting vulnerabilities, and elevated global risks. A menu of policy options is available to reduce the likelihood that the current debt wave will end in crisis and, if crises do take place, will alleviate their impact.

    A Mountain of Debt: Navigating the Legacy of the Pandemic
    (World Bank, Washington, DC, 2021-10) Kose, M. Ayhan ; Ohnsorge, Franziska ; Sugawara, Naotaka
    The COVID-19 pandemic has triggered a massive increase in global debt levels and exacerbated the trade-offs between the benefits and costs of accumulating government debt. This paper examines these trade-offs by putting the recent debt boom into a historical context. It reports three major findings. First, during the 2020 global recession, both global government and private debt levels rose to record highs, and at their fastest single-year pace, in five decades. Second, the debt-financed, massive fiscal support programs implemented during the pandemic supported activity and illustrated the benefits of accumulating debt. However, as the recovery gains traction, the balance of benefits and costs of debt accumulation could increasingly tilt toward costs. Third, more than two-thirds of emerging market and developing economies are currently in government debt booms. On average, the current booms have already lasted three years longer, and are accompanied by a considerably larger fiscal deterioration, than earlier booms. About half of the earlier debt booms were associated with financial crises in emerging market and developing economies.

    The Aftermath of Debt Surges
    (World Bank, Washington, DC, 2021-09) Kose, M. Ayhan ; Ohnsorge, Franziska ; Reinhart, Carmen ; Rogoff, Kenneth
    Debt in emerging market and developing economies (EMDEs) is at its highest level in half a century. In about nine out of 10 EMDEs, debt is higher now than it was in 2010 and, in half of the EMDEs, debt is more than 30 percentage points of gross domestic product higher. Historically, elevated debt levels increased the incidence of debt distress, particularly in EMDEs and particularly when financial market conditions turned less benign. This paper reviews an encompassing menu of options that have, in the past, helped lower debt burdens. Specifically, it examines orthodox options (enhancing growth, fiscal consolidation, privatization, and wealth taxation) and heterodox options (inflation, financial repression, debt default and restructuring). The mix of feasible options depends on country characteristics and the type of debt. However, none of these options comes without political, economic, and social costs. Some options may ultimately be ineffective unless vigorously implemented. Policy reversals in difficult times have been common. The challenges associated with debt reduction raise questions of global governance, including to what extent advanced economies can cast their net wider to cushion prospective shocks to EMDEs.

    Benefits and Costs of Debt: The Dose Makes the Poison
    (World Bank, Washington, DC, 2020-02) Kose, M. Ayhan ; Ohnsorge, Franziska ; Sugawara, Naotaka
    Government debt has risen substantially in emerging market and developing economies (EMDEs) since the global financial crisis. The current environment of low global interest rates and weak growth may appear to mitigate concerns about elevated debt levels. Considering currently subdued investment, additional government borrowing might also appear to be an attractive option for financing growth-enhancing initiatives such as investment in human and physical capital. However, history suggests caution. Despite low interest rates, debt was on a rising trajectory in half of EMDEs in 2018. In addition, the cost of rolling over debt can increase sharply during periods of financial stress and result in financial crises; elevated debt levels can limit the ability of governments to provide fiscal stimulus during downturns; and high debt can weigh on investment and long-term growth. Hence, EMDEs need to strike a careful balance between taking advantage of low interest rates and avoiding the potentially adverse consequences of excessive debt accumulation.

    One-Stop Source: A Global Database of Inflation
    (World Bank, Washington, DC, 2021-07) Ha, Jongrim ; Kose, M. Ayhan ; Ohnsorge, Franziska
    This paper introduces a global database that contains inflation series: (i) for a wide range of inflation measures (headline, food, energy, and core consumer price inflation; producer price inflation; and gross domestic product deflator changes); (ii) at multiple frequencies (monthly, quarterly and annual) for an extended period (1970–2021); and (iii) for a large number (up to 196) of countries. As it doubles the number of observations over the next-largest publicly available sources, the database constitutes a comprehensive, single source for inflation series. The paper illustrates the potential use of the database with three applications. First, it studies the evolution of inflation since 1970 and document the broad-based disinflation around the world over the past half-century, with global consumer price inflation down from a peak of roughly 17 percent in 1974 to 2.5 percent in 2020. Second, it examines the behavior of inflation during global recessions. Global inflation fell sharply (on average by 0.9 percentage points) in the year to the trough of global recessions and continued to decline even as recoveries got underway. In 2020, inflation declined less, and more briefly, than in any of the previous four global recessions over the past 50 years. Third, the paper analyzes the role of common factors in explaining movements in different measures of inflation. While, across all inflation measures, inflation synchronization has risen since the early 2000s, it has been much higher for inflation measures that involve a larger share of tradable goods.

    Global Recessions
    (World Bank, Washington, DC, 2020-03) Kose, M. Ayhan ; Sugawara, Naotaka ; Terrones, Marco E.
    The world economy has experienced four global recessions over the past seven decades: in 1975, 1982, 1991, and 2009. During each of these episodes, annual real per capita global gross domestic product contracted, and this contraction was accompanied by weakening of other key indicators of global economic activity. The global recessions were highly synchronized internationally, with severe economic and financial disruptions in many countries around the world. The 2009 global recession, set off by the global financial crisis, was by far the deepest and most synchronized of the four recessions. As the epicenter of the crisis, advanced economies felt the brunt of the recession. The subsequent expansion has been the weakest in the post-war period in advanced economies, as many of them have struggled to overcome the legacies of the crisis. In contrast, most emerging market and developing economies weathered the 2009 global recession relatively well and delivered a stronger recovery than after previous global recessions.
