Mortgage Rates May Be Low, But They’re Tough To Pin Down — Especially This Week

Mortgage rates are low right now but pinning them down this week could be a challenge. As Labor Day Weekend nears and Wall Streeters take their head-start on the holiday, trading volume will fall, which will cause mortgage rates to get jumpy.

As mortgage rates change, so does the long-term cost of owning a home. Every 1/8 percent adjustment changes a household budget.

Meanwhile, the relationship between “vacation days” and mortgage rate volatility is an interesting one; based more in scarcity than market fundamentals.

Rates tend to get volatile near holidays because of two inter-related facts:

1. Conforming mortgage rates are based on the price of mortgage-backed bonds
   
2. Mortgage-backed bonds can’t trade without a buyer and a seller at a specific price
   

So, as the week progresses and more traders leave for their respective “extended” 3-day weekends, there’s fewer buyers and sellers left on Wall Street to connect for a trade. As a result, mortgage bond prices move across larger gaps than on a “normal” day which, in turn, translates into faster, larger changes in rates.


This phenomenon can be exaggerated during periods of economic uncertainty — like what we’re in now — and, furthermore, there’s a bevy of important data set for release this week including the FOMC Minutes, inflation data, and August jobs figures.

In other words, rates would have been volatile without the vacation week. The presence of Labor Day just piles on.

Mortgage rates may rise this week, or they may fall. Either way, if you have a chance to lock something favorable and within your budget, consider doing it. Rates are at all-time lows and likely won’t last
