Government debt yields fell to multimonth lows Thursday, with the 10-year yield slumping below 2.1 percent as stock prices declined on worries over the global economic outlook.
The yield on the benchmark 10-year Treasury note closed at 2.127 percent, unchanged from Wednesday's close, which was its lowest since May.
The 30-year Treasury bond increased a full point in price, pushing the yield down by about 5 basis points to 2.76 percent. Prices move inversely to yields.

Yields on short-term maturities declined as well, albeit slightly. The yield curve between five-year notes and 30-year bonds narrowed to 127 basis points.
"I think that the Fed minutes have gotten us into questioning the assumption of a September rate hike," said Ian Lyngen, senior Treasury strategist at CRT Capital.
"We've seen that largely priced out of the market. We've seen global equities under pressure as well as domestic equities under pressure. With risk assets coming off, there's been a relative flight to quality."
