Loan relationships: special types of security: gilt-edged securities: indexed gilts

What are indexed gilts?

Indexed gilts were devised to encourage long-term investors, in particular, individuals, pension schemes and insurance companies with pension business, who wanted to protect the value of their investment against inflation.

Where a gilt is index-linked, the amount payable on redemption is wholly or partly calculated by reference to movements in the retail price index (RPI). So if, for example, a company

  • bought £70,000 of indexed gilts
  • RPI at issue was 140
  • RPI at redemption was 154
  • the amount repayable would reflect the change in RPI.
     
    The RPI has increased by 10%:
(154 -140)/140 x 100 = 10
     

(RPI) is based on January 1987 = 100.

The profit on redemption would be £70,000 x 10% = £7,000.
