Sub-Saharan Africa has been hit hard by the global recession, but signs of resilience remain. While South Africa and some other middle-income countries were caught in the turbulence of international financial markets, and oil exporters saw government revenues plunge, some countries with wider commodity bases have so far escaped the worst of the crisis. Also, and reassuringly, with stronger initial fiscal and external positions than in past downturns, most countries in the region have been able to partially absorb external shocks by allowing fiscal deficits to rise and reducing interest rates. Exchange rates have generally been allowed to adjust. With many families affected by the crisis, however, progress toward the Millennium Development Goals has receded. Looking ahead, fiscal policy must balance support for the recovery with enhancing future growth prospects, debt sustainability, and poverty reduction. Published biannually in May and October.

Global growth is in low gear, and the drivers of activity are changing. These dynamics raise new policy challenges. Advanced economies are growing again but must continue financial sector repair, pursue fiscal consolidation, and spur job growth. Emerging market economies face the dual challenges of slowing growth and tighter global financial conditions. This issue of the World Economic Outlook examines the potential spillovers from these transitions and the appropriate policy responses. Chapter 3 explores how output comovements are influenced by policy and financial shocks, growth surprises, and other linkages. Chapter 4 assesses why certain emerging market economies were able to avoid the classical boom-and-bust cycle in the face of volatile capital flows during the global financial crisis.

The world economy is experiencing a very strong but uneven recovery, with many emerging market and developing economies facing obstacles to vaccination. The global outlook remains uncertain, with major risks around the path of the pandemic and the possibility of financial stress amid large debt loads. Policy makers face a difficult balancing act as they seek to nurture the recovery while safeguarding price stability and fiscal sustainability. A comprehensive set of policies will be required to promote a strong recovery that mitigates inequality and enhances environmental sustainability, ultimately putting economies on a path of green, resilient, and inclusive development. Prominent among the necessary policies are efforts to lower trade costs so that trade can once again become a robust engine of growth. This year marks the 30th anniversary of the Global Economic Prospects. The Global Economic Prospects is a World Bank Group Flagship Report that examines global economic developments and prospects, with a special focus on emerging market and developing economies, on a semiannual basis (in January and June). Each edition includes analytical pieces on topical policy challenges faced by these economies.

The October 2010 Regional Economic Outlook features: (i) an overview of economic developments and prospects in sub-Saharan Africa; (ii) an analytical assessment of how monetary policy changes are transmitted through the region's economies; and (iii) a study of why growth rates in the West African Economic and Monetary Union (WAEMU) have lagged behind other parts of sub-Saharan Africa. The overview highlights the broad-based economic recovery that is now under way in sub-Saharan Africa and projects growth of 5 percent in 2010 and 51⁄2 percent in 2011. It explores the resilience of most economies in the region to the global financial crises of 2007-09 and explains why sound economic policy implementation and a growing orientation of trade toward Emerging Asia are expected to continue to underpin growth. The second chapter provides evidence suggesting that monetary policy may have more power to influence monetary conditions than previously assumed. Main messages from the WAEMU study are the importance of strong policy environments and political stability for achieving sustained growth; and of robust fiscal frameworks for directing resources towards priority spending needs.

The sharp decline in oil and other commodity prices have adversely impacted sub-Saharan Africa. Nevertheless, the region is projected to register another year of solid economic performance. In South Africa, however, growth is expected to remain lackluster, while in Guinea, Liberia, and Sierra Leone the Ebola outbreak continues to exact a heavy economic and social toll. This report also considers how sub-Saharan Africa can harness the demographic dividend from an unprecedented increase in the working age population, as well as the strength of the region's integration into global value chains.

This year looks set to be another encouraging one for most sub-Saharan African economies. Reflecting mainly strong demand but also elevated commodity prices, the region's economy is set to expand by more than 51⁄4 percent in 2011. For 2012, the IMF staff's baseline projection is for growth to be higher at 53⁄4 percent, owing to one-off boosts to production in a number of countries. There are, however, specters at the feast: the increase in global food and fuel prices, amplified by drought affecting parts of the region, has hit the budgets of the poor and sparked rising inflation, and hesitations in the global recovery threaten to weaken export and growth prospects. The projection for 2012 for the region is highly contingent on global economic growth being sustained at about 4 percent. A further slowing of growth in advanced economies, curtailing global demand, would generate significant headwinds for the region's ongoing expansion, with more globally integrated countries likely to be most affected. Policies in the coming months need to tread a fine line between addressing the challenges that strong growth and recent exogenous shocks have engendered and warding off the adverse effects of another global downturn. In some slower-growing, mostly middle-income countries without binding financial constraints, policies should clearly remain supportive of output growth, even more so if global growth sputters. Provided the global economy experiences the currently predicted slow and steady growth, most of the region's low-income countries should focus squarely on medium-term considerations in setting fiscal policy while tightening monetary policy wherever nonfood inflation has climbed above single digits. In the event of a global downturn, subject to financing constraints, policies in these countries should focus on maintaining planned spending initiatives, while allowing automatic stabilizers to operate on the revenue side. For the region's oil exporters, better terms of trade provide a good opportunity to build up policy buffers against further price volatility.

Sub-Saharan Africa's prospects have deteriorated somewhat and the risks have increased, according to this report. Growth in the region is projected to dip to 6 percent in 2008 and 2009. The fall is due mainly to the global food and fuel price shock, which has weighed particularly on growth in oil-importing countries, and to the global financial market turmoil, which has slowed global growth and demand for Africa's exports. Inflation is expected to rise to 12 percent in 2008, mainly on account of the food and fuel price shock. As a result of rising prices, particularly of food, poverty may well be on the increase in 2008. In 2009, inflation should ease to 10 percent, helped by recent commodity price declines. There are significant risks to the outlook related to a potentially deeper and longer period of global financial turmoil and resulting slowdown in global activity, and substantial uncertainty concerning commodity prices.
