U.S. Treasury yields edged higher, trading in narrow ranges as risk appetite improved a bit but worries over a trade conflict with China kept investors cautious.

The pan-European FTSEurofirst 300 index rose 1.18 percent and MSCI's gauge of stocks across the globe gained 0.65 percent. But the global index registered its biggest weekly drop for three months.
"It's not like stocks are getting a major bounce. It's a little stop of the bleeding. We're taking our breath and focusing on the oil market," said Ryan Detrick, senior market strategist at LPL Financial in Charlotte, North Carolina.
"Oil is the bigger story today with the OPEC news," he said.

U.S. crude rose 4.76 percent to $68.66 per barrel and Brent was last at $75.50, up 3.35 percent on the day.
"The effective increase in output can easily be absorbed by the market," Harry Tchilinguirian, head of oil strategy at French bank BNP Paribas, told the Reuters Global Oil Forum.
However, investors grew more nervous this week about the possibility of a full-blown trade war over increasingly sharp rhetoric between the United States and China, and growing evidence of the wider economic impact of this conflict.
