South African bonds were a few points weaker in late trade on Wednesday, on the back of the softer local currency. A local trader said the National Treasury's auction announcement had also caused a bit of "strain".
Earlier, the National Treasury announced that it would auction 600 million rand worth of R186 bonds and 1.5 billion rand worth of R209 bonds on June 14.
By 15:50, the benchmark R157 bond was trading at 7.410% from its previous close of 7.370%. The R207 was bid at 8.180% and offered at 8.150% from 8.125% and the R186 was trading at 8.360% and offered at 8.385% from 8.355%.
The rand was bid at 6.7409 against the dollar from 6.7041 late on Tuesday.
Earlier, another trader said the auction announcement was causing a bit of a problem.
"The guys are pumping that ultra-long end flat out and hence the curve is a bit weaker," he said.
