Beware of Greeks Bearing Primary Budget Surpluses

http://blogs.cfr.org/geographics/2013/12/04/greeksurpluses/

A primary budget surplus is a surplus of revenue over expenditure which ignores interest payments due on outstanding debt.  Its relevance is that the government can fund the country’s ongoing expenditure without needing to borrow more money; the need for borrowing arises only from the need to pay interest to holders of existing debt.  But the Greek government (as we have pointed out in previous posts) has far less incentive to pay, and far more negotiating leverage with, its creditors once it no longer needs to borrow from them to keep the country running.
This makes it more likely, rather than less, that Greece will default sometime next year.  As today’s Geo-Graphic shows, countries that have been in similar positions have done precisely this – defaulted just as their primary balance turned positive.
