Most of this has to do with the timing and intensity of yesterday’s market movement.  MBS weakened at a gentle pace throughout the day.  The losses were sufficient for several lenders to adjust rates higher, but most lenders kept rates unchanged from the morning.  Therein lies the problem.  While it’s true that bond markets are in stronger territory versus yesterday’s latest levels, they’re still not quite back to the levels in effect yesterday morning when lenders put out mortgage rate sheets.  Long story short, most lenders didn’t adjust rates to account for yesterday’s weakness and are simply getting caught up today.

3.625% is once again the most prevalent conventional 30yr fixed rate for top tier scenarios, although 3.5% is by no means extinct.  Tomorrow brings the much-anticipated vote on membership in the European union for the U.K. (aka “Brexit”).  As far as we know right now, the biggest risks from an interest rate standpoint won’t materialize until Friday morning, but we could see the effects as early as tomorrow afternoon.
