Rating agency Moody's on Tuesday placed Yes Bank under review for downgrade, owing to the private-sector lender's exposure to weak companies in the financial sector. The ongoing liquidity pressure on the country's finance companies is likely to impact credit profile, the rating agency also said in a note. The private sector lender has 'sizeable exposure' to weaker non banking financial companies (NBFCs), it added. "The review for downgrade takes into account Moody's expectation that the ongoing liquidity pressure on Indian finance companies will negatively impact the credit profile of Yes Bank, given the bank's sizeable exposure to weaker companies in the sector," the rating agency added. The global rating agency also said that it may downgrade rating if bank's capital ratio declines on its inability to raise capital.
