Johannesburg - South African government bonds weakened on Wednesday and the rand held steady against the dollar with investors wary of the uncertainty over Greece's debt negotiations with its creditors.
The yield on the 2026 benchmark instrument rose 8 basis point to 7.695% at 15:10 GMT, its highest in six weeks.
"There is a lot of fluctuation in the euro zone, Greece bonds due to the uncertainty," said Marten Banninga, head of bond trading at WWC Securities.
