Treasury yields hold near one-month lows

US Treasury yields edged higher on Thursday but held near one-month lows as fears about trade wars harming global growth kept up demand for safe haven bonds, while month- and quarter-end rebalancing added to bond buying.
Trade war fears have sent US stocks lower this week while sliding Chinese stocks and a weakening yuan has also raised concerns that there could be global contagion from the region. Stocks gained on Thursday, reducing some demand for Treasuries, however portfolio managers were seen as hesitant to take on much risk heading into the quarter-end.
"We're seeing a cautious conclusion to the quarter from the point of view of risk aversion," said John Herrmann, a director in rates strategies at MUFG Securities Americas in New York.
Benchmark 10-year notes fell 6/32 in price on the day to yield 2.849 percent. Yields earlier had dropped to 2.822 percent, the lowest since May 31.
The yield curve between two-year and 10-year notes traded at 32 basis points, the flattest level since 2007.
Chinese shares slumped to fresh two-year lows as trade tensions with the United States and worries about debt dimmed the outlook for China's economy.
Data showed that the US economy slowed more than previously estimated in the first quarter and the weakest performance in consumer spending in nearly five years, which economists blamed on escalating tensions between the United States and its trade partners.
A row over migration policy in Germany's coalition government has added to risk aversion.
Under severe pressure from conservative allies at home, German Chancellor Angela Merkel called on European leaders on Thursday to forge a common approach to migration, calling it a "make or break" issue for Europe.
The Treasury Department sold $30 billion in seven-year notes to fair demand, the final sale of $100 billion in short- and intermediate-dated supply this week.
The notes sold at a high yield of 2.809 percent, just below where the debt had traded before the auction. The Treasury saw solid demand for $34 billion in two-year notes on Tuesday and strong demand for $36 billion in five-year notes on Wednesday.
