South Africa’s Reserve Bank doesn’t anticipate a sudden stop of capital inflows as central banks in the U.S., European Union and Japan scale back bond-buying programs, deputy governor Lesetja Kganyago said.

Africa’s biggest economy relies on foreign capital to fund its current-account deficit, which widened to 6.5 percent of gross domestic product in the second quarter. The country also runs a budget deficit, which the National Treasury estimates at 4.2 percent of gross domestic product in the year through March 2014.

“South Africa is not a fragile country,” Bloomberg quoted Kganyago saying in a copy of a speech posted on the Pretoria-based bank’s website. “It is equipped to handle a shock like the end of quantitative easing. A flexible currency and rand-denominated debt protect South Africa.”

The twin deficits pose the biggest risk to the economy, which urgently needs to improve its export performance, Kganyago said.

Kganyago said South Africa’s policy wasn’ a responce to a weakening currency by defending its value, rather to target the pass-through to inflation. The rand has plummeted 17 percent against the dollar this year, the most among 16 major currencies monitored by Bloomberg.

“We see little evidence that a more activist and experimental approach would have changed the rand’s direction in a meaningful way,” Kganyago said.
