The global economy grew strongly in the first half of 2007, although turbulence in financial markets has clouded prospects. While the 2007 forecast has been little affected, the baseline projection for 2008 global growth has been reduced by almost 1⁄2 percentage point relative to the July 2007 World Economic Outlook Update. This would still leave global growth at a solid 43⁄4 percent, supported by generally sound fundamentals and strong momentum in emerging market economies. Risks to the outlook, however, are firmly on the downside, centered around the concern that financial market strains could deepen and trigger a more pronounced global slowdown. Thus, the immediate focus of policymakers is to restore more normal financial market conditions and safeguard the expansion. Additional risks to the outlook include potential inflation pressures, volatile oil markets, and the impact on emerging markets of strong foreign exchange inflows. At the same time, longer-term issues such as population aging, increasing resistance to globalization, and global warming are a source of concern.

The global expansion is losing speed in the face of a major financial crisis. The slowdown has been greatest in the advanced economies, particularly in the United States, where the housing market correction continues to exacerbate financial stress. The emerging and developing economies have so far been less affected by fi nancial market developments and have continued to grow at a rapid pace, led by China and India, although activity is beginning to slow in some countries. At the same time, headline infl ation has increased around the world, boosted by the continuing buoyancy of food and energy prices. Policymakers around the world are facing a diverse and fast-moving set of challenges, and although each country's circumstances differ, in an increasingly multipolar world it will be essential to meet these challenges broadly, taking full account of cross-border interactions. The World Economic Outlook (WEO) presents the IMF staff's analysis and projections of economic developments at the global level, in major country groups (classified by region, stage of development, etc.), and in many individual countries. It focuses on major economic policy issues as well as on the analysis of economic developments and prospects. It is usually prepared twice a year, as documentation for meetings of the International Monetary and Financial Committee, and forms the main instrument of the IMF's global surveillance activities.

The April 2012 issue of the World Economic Outlook assesses the prospects for the global economy, which has gradually strengthened after a major setback during 2011. The threat of a sharp global slowdown eased with improved activity in the United States and better policies in the euro area. Weak recovery will likely resume in the major advanced economies, and activity will remain relatively solid in most emerging and developing economies. However, recent improvements are very fragile. Policymakers must calibrate policies to support growth in the near term and must implement fundamental changes to achieve healthy growth in the medium term. Chapter 3 examines how policies directed at real estate markets can accelerate the improvement of household balance sheets and thus support otherwise anemic consumption. Chapter 4 examines how swings in commodity prices affect commodity-exporting economies, many of which have experienced a decade of good growth. With commodity prices unlikely to continue growing at the recent elevated pace, however, these economies may have to adapt their fiscal and other policies to lower potential output growth in the future.

Global economic activity is picking up with a long-awaited cyclical recovery in investment, manufacturing, and trade, according to Chapter 1 of this World Economic Outlook. World growth is expected to rise from 3.1 percent in 2016 to 3.5 percent in 2017 and 3.6 percent in 2018. Stronger activity, expectations of more robust global demand, reduced deflationary pressures, and optimistic financial markets are all upside developments. But structural impediments to a stronger recovery and a balance of risks that remains tilted to the downside, especially over the medium term, remain important challenges. Chapter 2 examines how changes in external conditions may affect the pace of income convergence between advanced and emerging market and developing economies. Chapter 3 looks at the declining share of income that goes to labor, including the root causes and how the trend affects inequality. Overall, this report stresses the need for credible strategies in advanced economies and in those whose markets are emerging and developing to tackle a number of common challenges in an integrated global economy.

After strong growth in 2017 and early 2018, global economic activity slowed notably in the second half of last year, reflecting a confluence of factors affecting major economies. China’s growth declined following a combination of needed regulatory tightening to rein in shadow banking and an increase in trade tensions with the United States. The euro area economy lost more momentum than expected as consumer and business confidence weakened and car production in Germany was disrupted by the introduction of new emission standards; investment dropped in Italy as sovereign spreads widened; and external demand, especially from emerging Asia, softened. Elsewhere, natural disasters hurt activity in Japan. Trade tensions increasingly took a toll on business confidence and, so, financial market sentiment worsened, with financial conditions tightening for vulnerable emerging markets in the spring of 2018 and then in advanced economies later in the year, weighing on global demand. Conditions have eased in 2019 as the US Federal Reserve signaled a more accommodative monetary policy stance and markets became more optimistic about a US–China trade deal, but they remain slightly more restrictive than in the fall.

This report describes the world economic outlook as of April 2018, projecting that advanced economies will continue to expand above their potential growth rates before decelerating, while growth in emerging markets in developing economies will rise before leveling off. It details global prospects and policies, including risks to the forecast, and essential determinants of long-term economic growth: labor force participation in advanced economies, the declining share of manufacturing jobs globally and in advanced economies, and the process through which innovative activity and technological knowledge spread across national borders.

The past year has been one of strong economic performance for the Western Hemisphere, notwithstanding somewhat slower growth in the United States in recent quarters. Can this performance be sustained, and what challenges does the region face? Reviewing macroeconomic prospects and risks, this report pays particular attention to the influence of the external environment on Latin America, and addresses the question of whether Latin America has now succeeded in breaking with its history of periodic growth reversals.

The recent economic and financial developments and trends in Asia and the Pacific are examined in this latest REO, including issues related to Asia’s trade performance, notably in the high-tech sector, and the February-March bout of turbulence in the region’s financial markets. The near-term outlook, key risks, and their related policy challenges are analyzed throughout, as well as in special chapters that look more closely at the evolving nature of capital inflows, housing market developments, and the impact of commodity price booms on lower-income economies.

The April 2011 edition of the World Economic Outlook assesses the global prospects for economic growth in the face of policy challenges that remain unaddressed and new challenges now coming to the fore.The recovery is gaining strength, but unemployment remains high in advanced economies, and new macroeconomic risks are building in emerging market economies. In advanced economies, the handoff from public to private demand is advancing, reducing concerns that diminishing fiscal policy support might cause a “double-dip” recession. Financial conditions continue to improve, although they remain unusually fragile. In many emerging market economies, demand is robust and overheating is a growing policy concern. Rising food and commodities prices present new risks to the global economy. Two chapters directly explore these new challenges. Chapter 3 reviews the potential impact of oil scarcity on global growth, and Chapter 4 explores the potential response of international capital flows to changes in the global macroeconomic environment.

This edition of the World Economic Outlook explores how a dramatic escalation of the financial crisis in September 2008 provoked an unprecedented contraction of activity and trade, despite active policy responses. It presents economic projections for 2009 and 2010, and also looks beyond the current crisis, considering factors that will shape the landscape of the global economy over the medium term, as businesses and households seek to repair the damage. The analysis also outlines the difficult policy challenges presented by the overwhelming imperative to take all steps necessary to restore financial stability and revive the global economy, and the longer-run need for national actions to be mutually supporting. The first of two analytical chapters, "What Kind of Economic Recovery?" explores the shape of the eventual recovery. The second, "The Transmission of Financial Stress from Advanced to Emerging and Developing Economies," focuses on the role of external financial linkages and financial stress in transmitting economic shocks.
