The major Vietnamese banks' ratings, already among the lowest in Asia, reflect difficult operating conditions and other structural issues typically found in low-income emerging markets.

Downside rating risks could arise if the operating environment becomes even more challenging than expected at this stage and significantly threatens banks'solvency, and/or due to negative rating action on the sovereign.
