Trade groups lobby for their members. The letter was ordinary behavior, and it carries little weight with the Fed. The National Association of Realtors represents real estate agents, the Mortgage Bankers Association represents mortgage lenders, and both memberships get hurt when higher rates freeze transaction volume. Their argument was the standard one: the Fed has tightened enough and can pause while the existing hikes work through an economy that responds with a lag of many months. We are sympathetic to the human side. When rates jump, a whole cohort of would-be buyers in their late twenties and thirties either cannot qualify or will not take on the payment, and that is a real cost. The Fed still weighs its own mandates first, maximum employment and stable prices, and if it believes more tightening is needed to control inflation, it will do it even with housing standing in the way. One mechanic worth knowing: policy can keep getting more restrictive without a single new hike. As inflation cools while the nominal rate holds steady, the real, inflation-adjusted rate rises, so the tightening keeps working on its own. That dynamic will do more to set your mortgage rate than any letter.
