• Hard call protection or absolute call protection is a condition of a callable bond, according to which the issuer cannot exercise the call and redeem the bond before a specified date, usually three to five years from the date of issue.

  • Hard call protection serves as a sweetener, as it ensures that investors receive the reported return within a protected period before the bond becomes “free” for call.
  • Callable bonds with strong call protection should be valued using the yield before call method.
