Moody’s has placed the credit ratings of four regional banking companies on review for downgrade, based their portfolio of energy loans, which are under pressure due to low oil prices. ‘We see energy companies defaulting, credit quality slipping, and so as that credit quality deteriorates, that increases probability of default,’ explained Joseph Pucella, VP-Sr. Credit Officer at Moody’s. Moody’s is now reviewing credit at BOK Financial (BOKF), Cullen/Frost Bankers (CFR), Hancock Holding (HBHC), and Texas Capital (TCBI). The outlook for the ratings of two other banks, Comerica (CMA) and Associated (ASBC) was changed to negative. Several of the banks have increased reserves for loan losses.
