Uneventful Day; MBS Underperform

It’s not uncommon to see MBS outperform their Treasury benchmarks in the run up to a round of weekly Treasury auctions only to underperform when the auction cycle wraps up. That underperformance (or rather, Treasury outperformance) was on full display today with MBS losing about a quarter point while 5yr notes lost about half as much. While bonds are slightly closer to the weaker end of the recent range, they’re still very much inside it.

Market Movement Recap

09:25 AM Moderately weaker so far with 5.0 coupons down 6 ticks (.19) and 10yr yields up 2.6bps at 4.143

11:45 AM flat since last update.  MBS down 6 ticks (.19) and 10yr up 1.9bps at 4.136

01:04 PM Slightly weaker bond auction = slightly weaker response.  MBS down 7 ticks (.22) and 10yr up 2.9bps at 4.146

It’s getting pretty tough to weave an interesting narrative on mortgage rates over the past 3 weeks. During that time, they just haven’t changed that much for the average lender. Today was just another day in that regard. Bonds (which dictate day to day movement in rates) were slightly weaker than yesterday. This implies slightly higher mortgage rates and, indeed, today was no exception. But the important points are as follows:
bond market movement has been relatively small on any given day
winning and losing days have been in relatively equal supply
Bottom line: today’s losses leave the average rate easily inside the narrow prevailing range.
