Loan officers at U.S. banks reported largely unchanged lending standards and slightly looser terms for business loans in the last three months of 2016, the Federal Reserve reported on Monday in a quarterly survey. About a third of the 69 institutions surveyed, however, said they had "tightened somewhat" the standards for commercial real estate construction and land development loans, and close to a fifth had tightened standards on loans secured by multifamily properties. The survey results indicate the effect of the Fed's recent interest rate increase may be falling differently across the economy.
