South African economy 5% bigger after rebasing, moving further ahead of Nigeria

South Africa’s economy is estimated to be ‌about 5% larger than previously reported after a benchmarking and rebasing exercise, its statistics agency said on Thursday, moving it further ahead of ​Nigeria as Sub-Saharan Africa’s biggest economy.

Statistics South Africa said ​last year’s nominal gross domestic product (GDP) was now estimated ⁠at 8.04 trillion rand (about $483 billion), up from 7.64 trillion ​rand.

Statistics agencies worldwide rebase and benchmark their GDP estimates to take ​into account changes in the composition of the economy and other factors.

Nigeria, Sub-Saharan Africa’s second-largest economy, recorded nominal GDP of 441.5 trillion naira ($328 billion) ​last year.

Nigeria used to have a bigger economy in dollar ​terms, but devaluations of its currency the naira meant South Africa overtook ‌it.

South ⁠Africa’s latest rebasing exercise changed the base year for its GDP calculations to 2022 from 2015.

It also incorporated previously non-observed parts of the economy like self-generation of electricity, illicit and illegal ​mining and manufacturing ​activity and ⁠e-hailing services.

The 10 sectors it tracks were all shown to have higher output, with mining, finance ​and trade registering the largest increases.

Johann Els, chief ​economist ⁠at financial services firm PSG, said the revisions to the size of the economy would make South Africa’s debt numbers look ⁠better, in ​particular its closely-watched debt-to-GDP ratio, which ​the government is trying to bring down.
