Standard and Poors Rating Services has corrected its long-term issuer credit rating on the Federal Home Loan Bank of Seattle by lowering it from AA+ to AA, S&P announced last week. The rating reflects FHLB Seattles unchanged stand-alone credit profile of A+, plus two notches of uplift to reflect expected extraordinary government support if needed, according to our government-related entity criteria, said the rating agency. The S&P outlook on the bank remains negative and this correction did not affect the Seattle banks short-term A-1+ rating or the ratings on the consolidated obligations of the Federal Home Loan Bank System.
