Treasuries are rallying in 2016 and corporate bonds are delivering even more as investors push back bets for when the Federal Reserve will raise interest rates as the central bank waits for the U.S. economy to pick up.
U.S. government securities have returned 3.2 percent this year while investment-grade company debt around the world has surged 5.2 percent, based on Bloomberg World Bond Indexes. High-yield bonds, the riskiest part of the fixed-income market, have gained 4.2 percent.
