Now that the dust has (almost!) settled on issues relating to LIBOR cessation in fund financing transactions (and the lending markets more generally), we are increasingly seeing market participants turning their attention to the rates now being used for financing transactions involving currencies which were previously funded on the basis of LIBOR.

One of the key differences between term reference rates (such as LIBOR) and the risk-free reference rates (whether on a "simple, daily" or a "compounded" basis) is that lending which is based on a term reference rate gives the involved parties certainty as to the amount of interest which will be payable for an interest period from the outset of that interest period (or very shortly thereafter). Conversely, in a transaction funded on the basis of a risk-free reference rate, the interest bill for an interest period can only be calculated shortly before the end of that interest period.
