The European Union lost its top credit rating from Standard & Poor's, which cited the deteriorating creditworthiness of the bloc's 28 member nations.
S&P cut its long-term rating on the EU to AA+, with a stable outlook, from AAA and maintained its short-term rating at A-1+. The downgrade came after S&P last month lowered its AAA rating on the Netherlands.
The list of countries that still have a AAA rating are shrinking:

but as the article says, these rating downgrades seem to have less of an impact these days.
