Some public infrastructure can be financed by the private sector. These project loans from banks, pension funds and the like are typically of low, investment-grade quality (e.g. BBB) because of the risks involved in project execution. Again, many are surprised to learn that we increasingly account for these loans as if they were Government debt in disguise. That is, we pretend that the loans are actually of top investment grade quality (e.g. currently AA-rated for the UK) even though they can (and do sometimes) fall into distress, with no hint of a Government bail-out in sight. It seems that when it comes to accounting for investment in infrastructure, we point the binoculars at a map and declare the world to be flat.
