When is borrowing at a low interest rate a bad thing for governments?

I was pleased to write an article for the Lowy Institute's great blog, The Interpreter, on Indonesia's regulation of toll roads entitled Indonesia's unorthodox toll road debt

From the article:

In 2016 Indonesia’s Ministry of Public Works dramatically underestimated the funds it needed to acquire land for toll road development. To try to keep development on schedule, the government leaned on toll road developers to lend them the difference at well-below-commercial rates. 

In the article, I try to set out how borrowing from the toll road developers at low interest rates may end up costing them more in the long run. To read more, head on over and have a read.
