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
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.
Inflation in Emerging and Developing Economies: Evolution, Drivers and Policies
(Washington, DC: World Bank, 2019) Ha, Jongrim; Kose, M. Ayhan; Ohnsorge, Franziska; Ha, Jongrim; Kose, M. Ayhan; Ohnsorge, Franziska; Ivanova, Anna; Laborde, David; Lakatos, Csilla; Martin, Will; Matsuoka, Hideaki; Montiel, Peter J.; Panizza, Ugo; Pedroni, Peter; Stocker, Marc; Unsal, Filiz D.; Vorisek, Dana; Yilmazkuday, Hakan
Emerging market and developing economies, like advanced economies, have experienced a remarkable decline in inflation over the past half-century. Yet, research into this development has focused almost exclusively on advanced economies. This book fills that gap, providing the first comprehensive and systematic analysis of inflation in emerging market and developing economies. It examines how inflation has evolved and become synchronized among economies; what drives inflation globally and domestically; where inflation expectations have become better-anchored; and how exchange rate fluctuations can pass through to inflation. To reach its conclusions, the book employs cutting edge empirical approaches. It also offers a rich data set of multiple measures of inflation for a virtually global sample of countries over a half-century to spur further research into this important topic.
What Types of Capital Flows Help Improve International Risk Sharing?
(World Bank, Washington, DC, 2021-11) Islamaj, Ergys; Kose, M. Ayhan
Cross-border capital flows are expected to lead to increased international risk sharing by facilitating borrowing and lending in global financial markets. This paper examines risk-sharing outcomes of various types of capital flows (foreign direct investment, portfolio equity, debt, remittance, and aid flows) in a large sample of emerging market and developing economies. The results suggest that remittances and aid flows are associated with increased international risk sharing. Other types of capital flows are not consistently correlated with better risk-sharing outcomes. These findings are robust to the use of different econometric specifications, country-specific characteristics, and other controls.
Challenges of Fiscal Policy in Emerging and Developing Economies
(Taylor and Francis, 2018) Huidrom, Raju; Kose, M. Ayhan; Ohnsorge, Franziska L.
This article presents a systematic analysis of the availability and use of fiscal space in emerging and developing economies. We report two major results. First, emerging and developing economies built fiscal space in the run-up to the Great Recession of 2008–2009, which was then used for stimulus. Since then, fiscal space has shrunk and remains narrow as these economies have taken advantage of historically low interest rates. Second, fiscal policy in emerging and developing economies has become countercyclical (or less procyclical), i.e., “graduated,” since the 1980s, as most clearly demonstrated during the Great Recession. The move towards graduation is most pronounced for those economies with greater fiscal space, which suggests that fiscal space matters for a government’s ability to implement countercyclical fiscal policy.
Understanding the Global Drivers of Inflation: How Important Are Oil Prices?
(World Bank, Washington, DC, 2023-01) Ha, Jongrim; Kose, M. Ayhan; Ohnsorge, Franziska; Yilmazkuday, Hakan
This paper examines the global drivers of inflation in 55 countries over 1970–2022. The paper estimates a Factor-Augmented Vector Autoregression model for each country and assess the importance of several global (demand, supply, and oil price) and domestic shocks. It reports three main results. First, global shocks have explained about 26 percent of inflation variation in a typical economy. Oil price shocks accounted for only about 4 percent of inflation variation, but they had a statistically significant impact on inflation in three-quarters of the countries. Second, global shocks have become more important in driving inflation variation over time. The share of inflation variance caused by oil price shocks increased from 4 percent prior to 2000 to roughly 9 percent during 2001–22. They also accounted for some of the steep runup in inflation between mid-2021 and mid-2022. Third, oil price shocks tended to contribute significantly more to inflation variation in advanced economies, countries with stronger global trade and financial linkages, commodity importers, net energy importers, countries without inflation-targeting regimes, and countries with pegged exchange rate regimes. The headline results are robust to a wide range of exercises—including alternative measures of global factors and oil prices—and aggregation of countries.
Explaining Recent Investment Weakness: Causes and Implications
(Taylor and Francis, 2019) Islamaj, Ergys; Kose, M. Ayhan; Ohnsorge, Franziska; Ye, Lei Sandy
This article investigates the drivers of investment growth in emerging market and developing economies with a focus on the most recent slowdown over the 2010–2015 period. Using panel regression techniques, we find that the recent investment slowdown in emerging market and developing economies is associated with a range of obstacles: weak economic activity, negative terms-of-trade shocks, declining foreign direct investment inflows, elevated private debt burdens, and heightened political risk. This stands in contrast with advanced economies, where weak economic activity is the most important factor. We briefly discuss policy implications of our findings.
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 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.
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.
