In the second interest rate hike for 2015, the South African Reserve Bank hiked the repo rate to 6.25%.
This follows a 25 basis point increase in July.
This brings the prime lending rate to 9.75%.
Jacques Du Toit, senior economist at Absa said the announcement came against the background of expected inflationary pressures due to the lagged effect of the severe drought on food prices, a weakening rand exchange rate and the prospect of rising interest rates in the United States before year-end and during next year.
Further hikes in lending rates are forecast for 2016, which will cause debt repayments to increase, contributing to additional financial strain on consumers.
Banks will continue to monitor economic and consumer-related trends, possibly impacting their risk appetite and lending criteria.
The rand, which was trading at R14.15/dollar shortly before the announcement, quickly weakened to R 14.20, but by 15:29 was trading back at R 14.15.
