CNBC reports that U.S. Treasury yields edged higher, as investors geared up for the Fed’s Jackson Hole symposium.

The yield on the benchmark 10-year Treasury note added less than a basis point, rising to 1.295%. The yield on the 30-year Treasury bond also rose less than a basis point at 1.916%.

The Fed’s annual Jackson Hole symposium, gathering central bankers from around the world, will kick off on Thursday.

Fed Chairman Jerome Powell is scheduled to make a speech at 14:00 GMT Friday, with investors listening for any details as to when the central bank will pare back its $120 billion a month bond-buying program.

Antoine Lesne, head of SPDR ETF strategy & research, EMEA at State Street Global Advisors, said that based on the improved economic data he believed that the Fed could start to talk about tapering, but that this would become more of a discussion at its September policy meeting.
