The 1980s are calling. According to Bloomberg:

Zambia’s kwacha fell the most on record after Moody’s Investors Service cut the credit rating of Africa’s second-biggest copper producer, a move the government rejected and told investors to ignore…..

Zambia’s economy faces “a perfect storm” of plunging prices for the copper it relies on for 70 percent of export earnings at the same time as its worst power shortage, Ronak Gopaldas, a credit risk analyst at Rand Merchant Bank in Johannesburg, said by phone. Growth will slow to 3.4 percent in 2015, missing the government’s revised target of 5 percent, Barclays Plc said in a note last week. That would be the most sluggish pace since 2001.

The looming debt crisis will hit Zambia and other commodity exporters hard. As I noted two years ago, the vast majority of the African countries that have floated dollar-denominated bonds are heavily dependent on commodity exports. Many of them are already experiencing fiscal blues on account of the global commodity slump (see for example Angola, Zambia and Ghana). This will probably get worse. And the double whammy of plummeting currencies and reduced commodity exports will increase the real cost of external debt (on top of fueling domestic inflation). I do not envy African central bankers.

Making sure that the looming debt crises do not result in a disastrous retrenchment of the state in Africa, like happened in the 1980s and 1990s, is perhaps the biggest development challenge of our time. Too bad all the attention within the development community is focused elsewhere.
