I don't get the impression that this headline and metric is useful. My understanding is that there are various ways of calculating the National Government's long term and short term financial obligations.

The proportion of debt to GDP is also only marginally useful and it is unknown if there is a level where market confidence is shaken. Isn't that the direction all threads on this topic go?
