U.S. Growth Decouples From Debt as JPMorgan Sees Lower Yield

The strengthening U.S. economy is proving no deterrent to the biggest rally in Treasuries since 2008, and America’s largest bank says it may get even better for bond investors.

U.S. government debt has returned 8.9 percent this year, including reinvested interest, Bank of America Merrill Lynch indexes show. That compares with the 1.8 percent gain in the Standard & Poor’s 500 index of stocks when dividends are included. The rally in Treasuries accelerated since October even as reports showed improvements in everything from consumer confidence to jobless claims to manufacturing.
