Moody's Investor Services expects
default rates
on junk bonds to increase to 4 percent this year, up from the 3.5
percent default rate in 2015. The default rate for all bonds is expected
to be 2.1 percent for 2015. Low commodity prices, widening yield
spreads, and potential interest rate increases by the Federal Reserve
are reasons given by Moody's. During 2015, there were 109 corporate
defaults, totaling $97.9 billion.
