The South African rand rallied on Monday after the country's embattled president, Jacob Zuma, bowed to market and political pressure and appointed his third finance minister in five days.
The benchmark Johannesburg All Shares Index traded as much as 2 percent higher on Monday, before paring gains, and shares in South Africa's banking index soared up to 16 percent on the news that Zuma had replaced his new finance minister with the more experienced Pravin Gordhan late on Sunday.
Zuma's U-turn came after the president , Nhlanhla Nene, last week and replaced him with outsider David van Rooyen. He then changed his mind following a wave of criticism and turmoil in currency, credit and equity markets at the end of the week.
"On the 9th of December 2015, I announced the appointment of a new Minister of Finance, Mr David van Rooyen. I have received many representations to reconsider my decision. As a democratic government, we emphasize the importance of listening to the people and to respond to their views," Zuma said in a statement on the South African government news agency late on Sunday.
"In this regard, I have, after serious consideration and reflection, taken the following decision; I have appointed Mr Pravin Gordhan, the current Minister of Cooperative Governance and Traditional Affairs as the new Minister of Finance."
Gordhan previously held the role of finance minister between 2009 and 2014, before becoming minister of cooperative governance and traditional affairs in May last year.
The rand is seen posting its strongest daily percentage gain on Monday since 2008, according to Reuters, due to relief at Gordhan's appointment.
London-listed shares of Investec and Old Mutual — two international banks that were founded in South Africa — traded as much as 10 percent higher on Monday, putting them among the top-performing stocks across Europe.
However, the revolving door at South Africa's finance ministry highlights doubts about Zuma's judgment.
Both Fitch Ratings and Standard & Poor's (S&P) have cut their ratings and outlooks on South Africa's sovereign debt earlier this month. Both Fitch Ratings and Standard & Poor's (S&P) cut their ratings and outlooks on South Africa's sovereign debt earlier this month.
"Zuma knows the investment grade rating is in serious trouble. So what does he do? He fires the one guy that's been trying to protect that rating. Nene's removal suggests that there was a clash with President Zuma about how deep the fiscal cuts should be," Brown Brothers Harriman (BBH) currency strategists said in a report on Friday.
Moody's Investors Service rates South Africa's debt one notch higher than S&P and Fitch, at Baa2 on its scale.
However, BBH rates the country at a lower BB/Ba2/BB, suggesting that South Africa's credit worthiness has already fallen into speculative or "junk" territory.
"We reiterate our long-standing call that the nation gets cut to sub-investment grade, and now it's likely sooner rather than later… We think a downgrade is a done deal," BBH said.
Nigeria overtook South Africa as Africa's biggest economy after the latter country rebased its gross domestic product (GDP) calculations in 2014. South Africa's economy is seen growing by 1.4 percent in 2015 and 1.3 percent in 2016, according to the International Monetary Fund.
