Abstract: | Little empirical work examines the extent to which commercial mortgage markets are integrated into broader capital markets. We use time series data on commercial mortgage yields and yields on comparable-maturity Treasury securities to identify a long-run cointegrating relationship between the two yield series. Our empirical evidence suggest that, while the yield on commercial mortgage is cointegrated with that on comparable-maturity Treasury securities, the cointegrating relationship is far less than that found between the yield on residential mortgage rates and that on comparable-maturity Treasury securities during 1980–1990 time period. However, our results also show that the spate of commercial mortgage securitization that began in early 1991 may have been a market-integrating force and caused the commercial mortgage market to become more integrated into broader capital markets. Indeed, our results suggest that changes in capital market rates are now much more rapidly reflected in commercial mortgage rates than in the 1980–1990 time period, although there is a lag. |
