The last decade has been punctuated by a series of broad-based economic crises and negative shocks, starting with the global financial crisis of 2008–2009, followed by the European sovereign debt crisis of 2010–2012 and the global commodity price realignments of 2014–2016. As these crises and the persistent headwinds that accompanied them subside, the world economy has strengthened, offering greater scope to reorient policy towards longer-term issues that hold back progress along the economic, social and environmental dimensions of sustainable development.
In 2017, global economic growth is estimated to have reached 3.0 per cent, a significant acceleration compared to growth of just 2.4 per cent in 2016, and the highest rate of global growth recorded since 2011. Labour market indicators continue to improve in a broad spectrum of countries, and roughly two-thirds of countries worldwide experienced stronger growth in 2017 than in the previous year. At the global level, growth is expected to remain steady at 3.0 per cent in 2018 and 2019.
The recent acceleration in world gross product growth stems predominantly from firmer growth in several developed economies, although East and South Asia remain the world’s most dynamic regions. Cyclical improvements in Argentina, Brazil, Nigeria and the Russian Federation, as these economies emerge from recession, also explain roughly a third of the rise in the rate of global growth between 2016 and 2017. But recent economic gains remain unevenly distributed across countries and regions, and many parts of the world have yet to regain a healthy rate of growth. Economic prospects for many commodity exporters remain challenging, underscoring the vulnerability to boom and bust cycles in countries that are overly reliant on a small number of natural resources. Moreover, the longer-term potential of the global economy carries a scar from the extended period of weak investment and low productivity growth that followed the global financial crisis.
Conditions for investment have generally improved, amid low financial volatility, reduced banking sector fragilities, recovery in some commodity sectors and a more solid global macroeconomic outlook. Financing costs generally remain low, and spreads have narrowed in many emerging markets, reflecting a decline in risk premia. This has supported rising capital flows to emerging markets, including a rise in cross-border lending, and stronger credit growth in both developed and developing economies.
Improved conditions have supported a modest revival in productive investment in some large economies. Gross fixed capital formation accounted for roughly 60 per cent of the acceleration in global economic activity in 2017. This improvement is relative to a very low starting point, following two years of exceptionally weak investment growth, and a prolonged episode of lacklustre global investment overall. A firmer and more broad-based rebound in investment activity, which is needed to support stronger productivity growth and accelerate progress towards the Sustainable Development Goals, may be deterred by elevated levels of trade policy uncertainty, considerable uncertainties regarding the impact of balance sheet adjustment in major central banks, as well as rising debt and a build-up of longer-term financial fragilities.
Global trade rebounded in 2017. In the first eight months of the year, world merchandise trade grew at its fastest pace in the post-crisis period. The rebound springs predominantly from stronger import demand in East Asia, as domestic demand picked up in the region, supported by accommodative policy measures. In several major developed economies, imports of capital goods have rebounded, as firms respond to improving conditions for investment. Recent course adjustments in major trade relationships, such as the United Kingdom of Great Britain and Northern Ireland’s decision to withdraw from the European Union and the United States of America’s decisions to renegotiate the North American Free Trade Agreement and to reassess the terms of its other existing trade agreements, have raised concerns over a potential escalation in trade barriers and disputes. These could be amplified if met by retaliatory measures by other countries. An increasingly restrictive trade environment may hinder medium-term growth prospects, given the mutually reinforcing linkages
between trade, investment and productivity growth. In this regard, policies should focus on upholding and revitalizing multilateral trade cooperation, emphasizing the possible benefits from trade in services.
