A bank issues a bond paying 8% interest annually forever without a maturity date—this is a perpetual bond.
Perpetual Bonds (also called perps) provide regular interest (coupon) payments forever, but the principal is typically not returned unless the issuer chooses to redeem it.
They are often issued by banks and financial institutions as part of regulatory capital, especially under Basel norms implemented by the Reserve Bank of India.
