Any sum secured over an interest in land under regulation 40 above shall bear interest from the day on which the standard security over that interest in land is recorded or, as the case may be, registered.

The rate of interest under paragraph (1) above shall be that which would apply (in the absence of any such statement as is provided for in Rule 7.7 of the Act of Sederunt (Rules of the Court of Session 1994) 199427) in the case of a decree pronounced or extracted in an action in the Court of Session on the day on which the sum begins to bear interest, if interest were included in, or exigible under, that decree.
