The upgrade of Krungsri's ratings reflects improvements in the Bank's solvency metrics, particularly in terms of capitalization and profitability, as well as Moody's Investors Service's expectation that the Bank's asset quality will remain largely stable over the next 12-18 months.
Moreover, the credit rating outlook reflects Moody's assumption of a very high likelihood of support from Krungsri's parent, MUFG. Also, Moody's considers the Bank to be a major subsidiary of MUFG in terms of profit contribution and strategic importance.
