Credit ratings for national governments - can anyone point to a cite?

I read, earlier this year, that one of the well-respected rating organizations had issued a report predicting the credit ratings of countries in Europe and the USA were expected to go drastically down over the next decade. Now, I cannot find the cite anywhere.

I’m not asking anyone to do my research for me, but if someone has a link or pointer to this information, I’d greatly appreciate them sharing it.

Thanks in advance!
