Botswana vs. Zambia

Until the beginning of the global recession in 2008, Botswana maintained one of the world's highest economic growth rates since its independence in 1966. Botswana recovered from the global recession in 2010, but only grew modestly until 2017, primarily due to a downturn in the global diamond market, though water and power shortages also played a role. Through fiscal discipline and sound management, Botswana has transformed itself from one of the poorest countries in the world five decades ago into a middle-income country with a per capita GDP of approximately $18,100 in 2017. Botswana also ranks as one of the least corrupt and best places to do business in Sub-Saharan Africa.

Because of its heavy reliance on diamond exports, Botswana's economy closely follows global price trends for that one commodity. Diamond mining fueled much of Botswana's past economic expansion and currently accounts for one-quarter of GDP, approximately 85% of export earnings, and about one-third of the government's revenues. In 2017, Diamond exports increased to the highest levels since 2013 at about 22 million carats of output, driving Botswana's economic growth to about 4.5% and increasing foreign exchange reserves to about 45% of GDP. De Beers, a major international diamond company, signed a 10-year deal with Botswana in 2012 and moved its rough stone sorting and trading division from London to Gaborone in 2013. The move was geared to support the development of Botswana's nascent downstream diamond industry.

Tourism is a secondary earner of foreign exchange and many Batswana engage in tourism-related services, subsistence farming, and cattle rearing. According to official government statistics, unemployment is around 20%, but unofficial estimates run much higher. The prevalence of HIV/AIDS is second highest in the world and threatens the country's impressive economic gains.

Zambia had one of the world's fastest growing economies for the ten years up to 2014, with real GDP growth averaging roughly 6.7% per annum, though growth slowed during the period 2015 to 2017, due to falling copper prices, reduced power generation, and depreciation of the kwacha. Zambia's lack of economic diversification and dependency on copper as its sole major export makes it vulnerable to fluctuations in the world commodities market and prices turned downward in 2015 due to declining demand from China; Zambia was overtaken by the Democratic Republic of Congo as Africa's largest copper producer. GDP growth picked up in 2017 as mineral prices rose.

Despite recent strong economic growth and its status as a lower middle-income country, widespread and extreme rural poverty and high unemployment levels remain significant problems, made worse by a high birth rate, a relatively high HIV/AIDS burden, by market-distorting agricultural and energy policies, and growing government debt. Zambia raised $7 billion from international investors by issuing separate sovereign bonds in 2012, 2014, and 2015. Concurrently, it issued over $4 billion in domestic debt and agreed to Chinese-financed infrastructure projects, significantly increasing the country's public debt burden to more than 60% of GDP. The government has considered refinancing $3 billion worth of Eurobonds and significant Chinese loans to cut debt servicing costs.
