In 2005, the UK prime RMBS market took one step further forward with the introduction of the first de- linked master trust in the United Kingdom (Granite Master Issuer), backed by the same pool of mortgages as the original structure, but requiring a second ‘funding’ (see Figure 3). ‘De-linked’ refers to the fact that it is possible to issue individual tranches rather than the full capital structure as long as following the issuance of each tranche – according to the rating agencies’ requirements – there remains sufficient credit enhancement for each class of bonds. The term ‘master issuer’ refers to a shelf issuance programme, which is familiar to many investors from medium-term notes programmes and is both time and cost effective. In theory, both the ability to issue advance issuance of subordinated bonds followed by subsequent independent issuance of senior notes and the advantage of using a shelf issuance programme enable a quicker response to reverse enquiries. This has yet to materialise in a way that has been common in US credit card asset-backed securities de-linked trusts, however.
