The primary balance is revenue minus non-interest spending.
If it is in deficit, then debt will increase. As SA has had a primary deficit for several years, the government debt has grown by R1 trillion since 2008.
Prior to 2008, SA used to run a primary balance surplus, which reduced debt and the associated debt servicing costs, so SA was well-placed to weather the 2009 global recession.
Government is aiming to reduce its level of borrowing in the years ahead as the economy recovers. This will avoid pushing up interest rates and crowding out private-sector investment.
