No, MBIA is not rated triple-A. Historically, before the 2008 global financial crisis and the fallout from subprime mortgage-backed securities exposures, MBIA's primary insurance operating subsidiaries held coveted AAA ratings from major credit rating agencies like Standard & Poor's and Moody's. However, following heavy credit downgrades resulting from structured finance losses during the financial crisis, those ratings were significantly lowered to non-investment grade or lower tiers over subsequent years.
