CG53440 | Debt on security: other debts deemed to be securities

From HM Revenue & Customs · Capital Gains Manual

Certain debts are specifically included in the definition of security for capital gains purposes. This treatment ensures that the exemption of gains under TCGA92/S251 (1), see CG53471, will not apply in these cases.

The circumstances where this applies are set out in CG53441-CG53444.
