SAn economy – “South Africa’s external debt now totals $136.6 billion or 38.2 percent of the country’s GDP – the highest level since the mid-1980s – due in large part to the emerging markets bond bubble that boosted foreign demand for the country’s bonds. South Africa’s external debt-to-GDP ratio was 25.1 percent just five years ago. $60.6 billion of South Africa’s external debt is denominated in foreign currencies, which exposes borrowers to the risk of rising debt burdens if the South African rand currency depreciates significantly, such as the currency’s 15 percent decline against the U.S. dollar in the past year. To make matters worse, over 150 percent worth of South Africa’s foreign exchange reserves are required to roll over its external debt that matures in 2014.”
