Such changes “come at a huge cost to the economy, paid with an inflation tax, which is levied disproportionately on the poor and vulnerable people in society,” the governor said.

South Africa’s ruling African National Congress has said it wants the central bank’s mandate broadened to shore up the economy and promote employment, in addition to its existing task of targeting inflation. The party is expected to face its toughest election this year since coming into power in 1994. The voting date has not yet been announced but must take place before the end of August.

Kganyago has regularly defended the reserve bank’s mandate to deliver price stability, stressing that it is enshrined in South Africa’s constitution. Last week he said expanding the mandate to include employment and economic growth won’t solve the structural issues in the country.

“If we do not have electricity, you are not going to have that growth,” he said. “If the logistics system is not working and mines are digging stuff out of the ground, but they can’t get their iron ore, or the coal or their manganese to the markets, because our national logistics system is not working, no expansion of the mandate of the central bank will solve those problems. We have got to be acting in sync.”

South Africans endure almost daily power cuts — known locally as load shedding — because years of neglect and mis-management have left state-run electricity utility Eskom Holdings SOC Ltd. unable to keep up with demand. Myriad problems also plague port and freight-rail operator Transnet SOC Ltd and their combined woes have crimped economic activity, stoked inflation and dented consumption.

The central bank’s monetary policy committee voted unanimously at its last meeting to leave the benchmark interest rate at a 2009 high of 8.25% for a fourth consecutive time.

Before pausing in July, the bank had hiked rates at 10 meetings to rein in inflation that remains above the 4.5% midpoint of its target range, where it prefers to anchor expectations. Kganyago has said the MPC won’t cut rates for as long as there isn’t any sustained decline of inflation towards the midpoint of its target band.
