Developing countries should prepare for a long period of volatility in the global economy by re-emphasizing medium-term development strategies, while preparing for tougher times, says the World Bank in the newly-released Global Economic Prospects (GEP), June 2012.

A resurgence of tensions in high-income Europe has eroded the gains made during the first four months of this year, which saw a rebound in economic activity in both developing and advanced countries and an easing of risk aversion among investors. Since May 1st, increased market jitters have spread. Developing and high-income country stock markets have lost some 7 percent, giving up two-thirds of the gains generated over the preceding four months. Most industrial commodity prices are down, with crude and copper prices down by 19 and 14 percent, respectively, while developing country currencies have lost value against the US dollar, as international capital fled to safe-haven assets, such as German and U.S. government bonds.

So far, conditions in most developing countries have not deteriorated as much as in the fourth quarter of 2011. Outside of Europe and Central Asia and the Middle-East and North Africa, developing country credit default swap (CDS) rates, a key indicator of market sentiment, remain well below their maximums from the fall of 2011.

"Global capital market and investor sentiment are likely to remain volatile over the medium term - making economic policy setting difficult.

In this environment, developing countries should focus on productivity-enhancing reforms and infrastructure investment instead of reacting to day-to-day changes in the international environment," said Hans Timmer, Director of Development Prospects at the World Bank.
