SEOUL: South Korean bonds rallied on Wednesday, with the yield on the benchmark 10-year government debt falling the most in 1-1/2 months, as weak US jobs data spurred expectations that the Federal Reserve will delay tapering its bond-buying stimulus.

The yield on the 10-year treasury bonds fell 9.0 basis points, marking the biggest daily fall since Sept. 9, while lead December futures on three-year treasury bonds ended up 0.17 point at 106.07.
