Treasuries Little Changed as Investors Await Speech by Fed Chief

Treasuries were little changed before a speech by Federal Reserve Chair Janet Yellen amid speculation on whether she’ll refrain from signaling interest rates will rise sooner than the market anticipates, even as growth picks up.

Ten-year bond yields declined earlier as investors sought haven assets amid rising tensions in Ukraine after the nation declared a Russian aid convoy as an invasion. Yellen will speak today at an annual conference of central bankers in Jackson Hole, Wyoming. The extra yield investors demand to hold 10-year Treasuries over their Group-of-Seven peers was near the widest this month as a measure of whether U.S. economic data is beating expectations approached the highest since February.
