The delinquency rate of loans in commercial mortgage-backed securities bounced higher in December and remained above 9% all year.

Delinquency rates were mixed across the five commercial property types in December with hotel and multifamily rates declining while office, retail and industrial rose.

Moody’s Investors Service said the rate rose to 9.32% last month from 9.27% in November and from 8.79% a year earlier. (Click on chart to expand.)

The ratings agency said there were $3.7 billion of newly delinquent loans in December, including Bank of America Plaza in Atlanta, while $3.5 billion were resolved or worked out. The $1.4 billion of new CMBS deals was more than offset by $5.5 billion of seasoned loan dispositions and payoffs, pushing the CMBS universe to $582.8 billion, analysts said.

The $363 million loan that went into arrears in Atlanta is the seventh largest delinquent loan overall, according to Moody’s.

The delinquent rate in the hotel sector fell to 12.96% from 13.54% a month earlier, while multifamily declined to 14.44% from 14.88%, which remains the highest rate among the core asset classes, Moody’s said.

Retail delinquencies rose to 7.22% from 6.97% in November; industrial climbed to 12.09% from 11.5%; and office increased to 8.65% from 8.39%.

Moody’s specially serviced loan tracker fell to 11.97% in December from 12.1% the prior month.
