Moody's Investors Service has confirmed Bahrain Islamic Bank's (BIsB) supported issuer ratings at Ba3, with a negative outlook, and affirmed its short term ratings at Not Prime. At the same time, Moody's downgraded BIsB's standalone bank financial strength rating (BFSR) by one notch to E from E+, equivalent to a baseline credit assessment (BCA) of caa1 from b3 previously. Moody's downgrade of the standalone credit profile reflects BIsB's still thin and vulnerable capital base, given the continued lack of clarity surrounding the timing, nature and amount of the anticipated capital injection. These weaknesses are partially moderated by BIsB's solid funding and liquidity position.The negative outlook on the supported issuer rating is aligned with negative outlook on the ratings of the Government of Bahrain, the ultimate provider of systemic support to the bank.
