US MBA 30-Year Mortgage Rate (Jul/17) 6.69%

The established pattern is that the rate itself tracks the long end of the Treasury curve with a lag, so the informational content for fixed income desks is minimal; the signal sits in whether application volumes respond to moves in the rate, which is the live test of housing elasticity at prevailing levels. Prints in the upper part of the recent range have tended to suppress refi activity sharply while purchase volumes prove stickier, a distinction worth drawing between the two components. Follow-ons are the builders' sentiment, starts, and existing home sales data later in the housing calendar, which confirm or contradict what the applications data imply. As a standalone number without the survey detail, there is little to act on here.
