Treasuries gained for a fourth straight day amid concern about the U.S. debt ceiling and a reduction in the World Bank’s growth forecasts.
The rate on 10-year Treasuries declined one basis point to 1.82 percent, near the lowest level in two weeks.
Thirty-year yields also decreased for a fourth day, slipping one basis point to 3.02%.
U.S. government debt remained higher after a report showed inflation remains at bay, allowing the Federal Reserve to add monetary stimulus without triggering a surge in prices.
