The local currency was trading at R7.71 to the dollar at 17:44 GMT, 0.9% stronger than its previous close in New York, after see-sawing between R7.6775 and R7.82 during the session.
Government bonds tracked the rand's move in relatively light trade, pulling back some of their sizable losses sparked by investor concern over an expected easing in economic growth.
Dealers said trade was largely flow-driven with dollar buying out of London early in the day paring gains before it drifted back on higher stocks and broader emerging market gains as those flows waned.
"Emerging markets are stronger, the dollar is weaker against the euro and local stocks are up on the Dow (Jones index) and we are just picking up that on the currency," ABN AMRO trader Paul Peter said.
Gold fell as much as 1% as the dollar gained ground versus the euro after Warren Buffett told CNBC television that he had offered to take over the liabilities of monoline bond insurers. But the metal later pared losses.
Platinum rose to a high of $1 965 an ounce before falling to $1 943/1 950 by 17:50, against $1 933/1 941 in New York late on Monday.
"You know that platinum demand is increasing on the back of emission controls and you know that supplies are going to be squeezed. So it just makes sense to be long in this market," said Johannesburg-based Walter De Wet, analyst at Standard Bank.
"There might be slight over-reaction as everybody is on the bandwagon because of the recent price rise, but there is also some realisation that things are going to get tighter. We believe that the bias is on the upside."
Platinum's rally, which has sent prices up 30% in just three weeks, gained pace after Anglo Platinum, the world's biggest producer, said on Monday the power problem alone would cut output by as much as 120 000 ounces in 2008. It had already cost 30 000 ounces in lost output this year.
Northam Platinum said on Tuesday its production fell 16.5% to 150 755 ounces the July-December period of 2007 from a year earlier and saw its output at the same level in the next six months, provided mines got 90% power.
The market nervously awaits financial results of Impala Platinum, the world's second-biggest producer of the metal, on Thursday for more cues on total production losses.
"It's a chronic problem. It has been a deficit market for many years and it looks like it has returned to a significant deficit market again," said David Holmes, director of metals sales at Dresdner Kleinwort Investment Bank.
Mines across South Africa, which accounts for four-fifths of the world's supply of the metal, ground to a halt for five days at the height of the power crisis last month. Platinum is used in jewellery and auto catalysts to clean exhaust fumes.
Negotiations were under way for South African state-owned power utility Eskom to buy surplus electricity from local producers as part of its bid to solve the nation's energy crisis, Public Enterprises Minister Alec Erwin said on Monday.
Citigroup Inc., Bank of America Corp. and JPMorgan Chase & Co., the three largest U.S. banks, climbed after Buffett said he's willing to take on $800 billion in municipal bond obligations in an interview with CNBC.

The Nasdaq Composite Index climbed 15.24, or 0.7 percent, to 2,335.3. More than three stocks rose for every one that fell on the New York Stock Exchange. Shares in Europe and Asia also gained.
``It's another potential solution to some of the credit problems,'' Mark Bronzo, who helps manage $11 billion at Security Global Investors in Irvington, New York, said of Buffett's offer. ``That's why the markets are responding well.''
Concern that bond insurers don't have enough money to pay claims on the $2.4 trillion in assets they guarantee has contributed to a 7.4 percent drop in S&P 500 financial shares in 2008. MBIA Inc., the largest bond insurer, lost 80 percent of its value in the last year before today, and smaller rival Ambac Financial Group Inc. slumped 88 percent, on concern that the companies will lose their AAA credit ratings.
Buffett's Offer
Citigroup added 73 cents to $26.54. Bank of America rallied 66 cents to $42.80. JPMorgan climbed 46 cents to $43.81. Bear Stearns Cos., the fifth-biggest U.S. securities firm, increased 49 cents to $80.25.
Buffett said he offered to take on the municipal-bond liabilities of MBIA, Ambac Financial and FGIC Corp. Buffett's Berkshire Hathaway Inc. would provide so-called reinsurance for the debt, he said in an interview with CNBC television.
One company turned down the offer and the two others haven't responded, Buffett, chairman of Berkshire Hathaway Inc., told CNBC.
MBIA slipped 79 cents to $12.79. Ambac lost 29 cents to $10.19. Buffett's offer doesn't include the insurers' subprime- related obligations.
'Project Lifeline'
Financial shares also climbed on plans to help delinquent homeowners avoid foreclosure. Bank of America, Citigroup and four other U.S. lenders announced a plan to offer a 30-day freeze on home foreclosures while loan modifications are considered. Treasury Secretary Henry Paulson and U.S. Housing and Urban Development Secretary Alphonso Jackson said today at a news conference in Washington that ``Project Lifeline'' would help stabilize communities disrupted by mortgage defaults.

Schlumberger Ltd. advanced $2.57 to $83.06 after Bear Stearns raised its recommendation on the world's largest oilfield-services provider to ``outperform'' from ``peer perform,'' saying the company's offshore drilling and exploration make it ``well positioned for the next phase of the oilfield service business cycle.''
Schering-Plough
Schering-Plough Corp. gained $1.16 to $21.78. The maker of Vytorin and Zetia cholesterol pills reported fourth-quarter profit, excluding some items, of 52 cents a share, beating the 27-cent average estimate of 17 analysts surveyed by Bloomberg.
General Motors Corp., the world's largest automaker, gained after reporting an adjusted fourth-quarter profit, not counting costs and gains the company considers one-time items, of 8 cents a share. On that basis, analysts estimated a loss of 64 cents. GM's net loss in the quarter was $722 million.

NxStage Medical Inc. fell the most since its 2005 initial public offering, dropping $3.30, or 26 percent, to $9.45. The maker of portable dialysis systems said it expects a loss of as much as $1.52 a share in 2008, wider than the $1.06 loss estimated by analysts in a Bloomberg survey.
