A permanent interest bearing share is a non-redeemable interest-paying security often issued by building societies or similar institutions.
Permanent Interest Bearing Shares (PIBS) are a specialized financial instrument primarily issued by building societies. This article delves into their historical context, types, key events, characteristics, risks, applicability, and market considerations.
The market size for PIBS is relatively small, estimated at around £800 million. This can lead to volatility and difficulties in price determination.
The yield on a PIBS can be calculated using the formula for fixed-income securities:
PIBS are essential for investors seeking stable and high-yield income. They are particularly relevant for pensioners and income-focused investors.
For finance readers, Permanent Interest Bearing Share is useful when reviewing cash-flow timing, risk transfer, pricing, reporting, and decision impact across the finance workflow.

Ask whether Permanent Interest Bearing Share changes amount, timing, probability, liquidity, rights, reporting, or control evidence. If it does not, keep Permanent Interest Bearing Share as context; if it does, tie it to the recommendation, valuation input, control step, disclosure, or risk decision.
