Perpetual bond

Perpetual bond, which is also known as a perpetual or just a perp, is a bond with no maturity date. Therefore, it may be treated as equity, not as debt. Issuers pay coupons on perpetual bonds forever, and they do not have to redeem the principal. Perpetual bond cash flows are, therefore, those of a perpetuity.

Examples

Examples of perpetual bonds are consols issued by the UK Government. Most perpetual bonds issued nowadays are deeply subordinated bonds issued by banks. The bonds are counted as Tier 1 capital and help the banks fulfill their capital requirements. Most of these bonds are callable, but the first call date is never less than five years from the date of issue—a call protection period.

One of the oldest examples of a perpetual bond was issued in 1648 by the Dutch water board of Lekdijk Bovendams. It is currently in the possession of Yale university and interest was most recently paid in 2015.
