Fitch Ratings said it has affirmed the ‘AAA’ long-term issuer default rating and support floors of the Federal Home Loan Bank of Atlanta.Fitch noted that as a GSE, the Atlanta Bank’s IDRs are linked to the U.S. sovereign rating. “FHLBank Atlanta has historically benefited from its affiliation with the U.S. government and its current IDRs and outlook benefit from the implicit support that it receives,” said the rating agency. “Fitch believes that implicit sovereign support for the FHLBank system would be forthcoming due to its important mission as it pertains to homeownership, serving as a source of liquidity to its members and the wide global distribution of FHLBanks debt.”
