- Full faith and credit: Moody’s Investors Service warns that a failure by the U.S. Congress to come to an agreement on raising the debt limit could imperil the country’s AAA credit rating: “The heightened polarization over the debt limit has increased the odds of a short-lived default. If this situation remains unchanged in coming weeks, Moody’s will place the rating under review.” You may remember a similar warning from Standard and Poor’s last April — it’s becoming increasingly clear that the debt limit struggle, in addition to the gaping chasm between what Democrats and Republicans would care to do on spending and deficit issues (such a chasm usually means gridlock), is causing angst for financial agencies. source
