Commercial real estate loans outstanding have grown slightly over 100% in a decade. CRE borrowers took advantage of the incredibly low interest rates, an economy recovering from the Global Financial Crisis, and banks that in too many cases were less than diligent in underwriting loans. Presently, the amount of commercial real estate loans, as a percent of banks’ total loans, has grown to being slightly higher than it was in the last quarter of 2007. This worries me.
