Delinquencies on mortgages for hotels, shopping malls and office buildings were sharply higher in the fourth quarter, as the weaker economy hit landlords and threatens to cause losses for investors in the $3.4 trillion market.

Commercial real estate has held up better than the housing market, but began to struggle at the end of last year. New data from Deutsche Bank show that delinquencies on commercial mortgages packaged and sold as bonds, which represent nearly a third of the commercial real-estate debt market, nearly doubled during the past three months, to about 1.2%.
