While this week's rates were substantially higher than most of last week's, if we remove a few flashes of volatility,  the average lender stayed very close to Monday morning's levels.  Wednesday afternoon and Thursday mid-day definitely saw multiple negative reprices, but in each case, the bond market recovered enough to limit the volatility.  Compared to last week, it may as well have been a flat line.

The following chart shows the mortgage backed securities (MBS) prices that directly dictate mortgage rate movement.  Higher prices = lower rates and vice versa.

Today's economic data included a wholesale inflation report that has occasionally caused some volatility, but today's installment was not one of them.  The bond market improved a bit heading into the afternoon and traded calmly from there.  As such, mortgage lenders were not compelled to make any negative mid-day changes after setting this morning's rates very close to yesterday's latest levels. 

The next time lenders have a chance to set mortgage rates for the day will be Tuesday due to the market closure on Monday for Indigenous Peoples' Day.
