No Improvement in Illinois’ Ranking / MyRadioLink.com August 04, 2016 10:17 am Illinois still has the worst credit rating in the United States. Moody’s Investors Service recently lowered the state’s rating from a BAA1 rating to BAA2. That’s just two spots above junk status. The change came with a difference of $26-billion in general debt. As a result, taxpayers will likely end up paying more when the state borrows funds. The service lists the state’s future outlook as negative.
