The decision follows the first three-day meeting of the year by the Monetary Policy Committee (MPC).

"The MPC has unanimously decided to keep the repurchase rate unchanged at 5.75% per annum," Kganyago said.

According to the bank, food prices remain a major source of inflation pressure. However, the moderation observed in recent months is expected to continue.

The rand exchange rate against the US dollar remains an upside risk to the inflation outlook.

Additionally wage and salary increases in excess of inflation and productivity growth remain an upside risk to the inflation outlook.

When coming to electricity constraints, the bank said the impact of monetary policy accommodation or growth is likely to be limited in the absence of progress being made in the alleviation of electricity constraints.

The repo rate has remained unchanged since a 25 basis points rate hike in July 2014. Market consensus was for the repo rate to remain unchanged.

Kganyago said the MPC is aware that the moderation in inflation could raise expectations of lower interest rates. The MPC is of the view that the bar for further accommodation remains high and would require a sustained decline in the inflation rate and inflation expectations.

Core inflation is expected to average 5.5% and 5.1% in 2015 and 2016 respectively, from 5.7% and 5.3% previously. The peak is expected at 5.8% in the first quarter of 2015.

The MPC said the domestic economic growth outlook remains subdued.

The bank's forecast for growth in 2015 has been revised down from 2.5% to 2.2%, and that for 2016 from 2.9% to 2.4%.

"This forecast attempts to take account of electricity supply disruptions, which more than offset the positive growth impact of lower oil prices."
