At 0645 GMT the rand was 0.23% firmer at 15.2800 per dollar, recovering from a slide to a 5-week low of 15.3525 overnight as the greenback raced to new highs against most currencies as U.S Treasury yields rose again.
Rising U.S. bonds yields and the possibility of the Federal Reserve retreating from its massive bond buying programme has fuelled fears of another "taper tantrum" like in 2013 when emerging markets were hit hard.
But on Thursday Federal Reserve Chair Jerome Powell reiterated a commitment to maintain ultra-easy monetary policy.
Low lending rates in the United States and other developed markets typically benefit high-yielding emerging market currencies like the rand that offer higher returns for the perceived higher risk.
But Powell's remarks on inflation, a likely trigger for rate hikes, and still rising yields on U.S. bonds, kept risk appetite subdued.
"Make no mistake, if U.S. rates continue to rise and we see the offshoots of inflation, emerging markets are going to Pain City," chief trader at Standard Bank, Warrick Butler, said in a note.
Bonds continued their diversion from the currency. The yield on the benchmark 2030 government issue added 10 basis overnight to 9.240%, it highest level since early November.
