Big Shift Toward 5.0 Coupons Continues

Big Shift Toward 5.0 Coupons Continues

Mortgage rates have lurched rapidly lower in September as 5.0 UMBS have stolen the show from 5.5 UMBS. As a reminder, there is only a certain range of rates allowed in either bucket. 5.5s go all the way up to 6.625% and investors buying MBS would prefer not to get stuck holding a burning bag of 6.625% loans in a market where those borrowers are already on the edge of being in the money on a refi. Bottom line, it's the fastest/biggest shift in 5.0 outperformance since late 2023, and today's installment brought the spread between the two coupons to the tightest levels since early October 2024.  Lo and behold, that's the last time rates were in this territory. Spreads spiked back to wider levels on October 4th owing to a strong jobs report. This October's jobs report will be in focus for similar reasons, but before that, near-term volatility risks surround Wednesday's Fed dot plot.

Big Shift Toward 5.0 MBS Continues

The only downside of this morning's post-data recovery was that it set a higher level for MBS during some lenders' rate sheet print times. From those highs around 9:45am, MBS are now down 5 ticks (.16) despite being down only 1 tick on the day.  The jumpier lenders who released rates at or shortly after 9:45am could technically justify a negative reprice assuming they passed along the gains that were present at the time.  In other words, if the lender in question...   READ MORE

Mortgage rates dropped sharply lower today relative to the amount of movement in the underlying bond market with the average lender right in line with the lowest levels since late 2022. Because rates are directly tied to the prices of those bonds, the correlation tends to be almost perfect over time. [thirtyyearmortgagerates] But there are always scattered examples of one leap-frogging the other. These inconsistencies can arise for several reasons. In today's case, it hap...   READ MORE

Markets have settled into a cycle that favors the jobs report as the only critical economic data as far as rates are concerned. This week's inflation data had a chance to claim/preserve a role as a strong supporting actor, but instead, it basically stood aside and left focus on the labor market and the Fed's interpretation of recent labor market weakness. A majority of the notion of "recent lab... READ MORE
