Bonds in Default

When a municipal bond issuer stops making payments, the bond enters default and trades differently from normal bonds. This pricing distinction is frequently tested.


How Defaulted Bonds Trade

When a municipal bond is in default (the issuer has failed to make interest or principal payments):

  • The bond does not accrue interest - interest stops accumulating
  • The bond trades flat (without accrued interest) - the buyer does NOT pay accrued interest to the seller
  • The price reflects the market's estimate of recovery value (what investors expect to recover)

Other bonds that trade flat:

  • Income bonds (also called adjustment bonds): corporate bonds that pay interest only if the issuer earns sufficient income
  • Zero-coupon bonds: no coupon payments are made, so there is no accrued interest to add

Exam Tip: Gotchas

  • A bond in default does NOT accrue interest. No exceptions.
  • "Trades flat" means the buyer pays NO accrued interest. The price is all the buyer pays.
  • Income bonds also trade flat. These are corporate bonds, not municipal bonds. A common mix-up is confusing the two.
