Interesting take on that from a budget note by a BNP Paribas economist:
While there’s an increasing risk of populism, which would see the government spend more freely to shore up voter support ahead of elections next year, contingency and unallocated reserves give the state room to maneuver and reach compromises without blowing the fiscal framework
Love how they used the PC approach by stating 'shore up voter support' instead of calling a spade a spade: The ANC will use spending to buy votes ahead of the 2024 elections!
They won't do anything drastic until next year after the elections. There is enough time to carry on borrowing more, since bonds only need to be repaid many years in the future.
