The Budget Review indicates that government's net debt is expected to increase from R690 billion in 2009-10 to R1,3 trillion in 2012-13, and as a result, debt service costs are budgeted to increase from R57,6 billion to R104 billion over this period. The net debt and debt service costs as a percentage of gross domestic product, GDP, will increase to 40% and 3,2%, respectively, over the next three years. The national government debt is projected to peak at about 44% of GDP in 2015-16, before stabilising.
