The influx of private capital raises the question of whether Africa is on the verge of a China-style breakout phase.

As the Olympic glow fades in China, it is time to shift our attention to Africa, which some analysts are talking up as the next emerging-market hot spot. A continent once shunned by international investors is now attracting interest, as a number of leading African nations begin to spend revenues generated by the recent global commodity price boom to stabilize their economies. Recent increases in the flow of private capital raise the question of whether Africa is on the verge of a China-style breakout, one that has extremely important consequences for global welfare, as it could dramatically change the lives of millions of poor Africans if it spreads. Unfortunately, much of the new progress is still too narrowly focused--on specific sectors like raw-materials extraction, and a limited number of countries led by Ghana and Uganda--to justify a generalized "Africa bet" today.

The macroeconomic numbers are clear: Africa as a whole is on the rise. After decades of subpar performance that undermined social stability and fed poverty, regionwide economic growth hit an annual average of 4 percent from 1997 to 2002 and rose to 6 percent in the following five years. During the same period, inflation declined from more than 13 percent to 8 percent, and the financial balance sheets started to look reasonably healthy for the first time in memory. International reserves have risen from less than four months of imports of goods and services to a comfortable six months. Debt to official creditors, who have long claimed too big a chunk of meager African government revenues, is down from 45 percent of GDP to less than 10 percent.

The improved economic and financial picture now makes Africa relatively attractive at a time of financial turmoil in many industrial countries. Inflows of capital from foreign investors have quadrupled over the course of a decade to $22.5 billion in 2006, according to the IMF, albeit from a low base. The credit ratings of several African countries are on the rise and, most important in my eyes, spending on health, education, housing and other social services is expanding.

Still, it's too early to call Africa the next China. The continent has been turbocharged by spiking prices for various agricultural and energy-related export commodities. A number of countries prudently invested the windfall revenues. Those moves buffered these countries against the recent fall in commodity prices.

Yet there are still major problems. High political risk in Africa ...
