Mortgage rates rose somewhat sharply yesterday to match the highest level since March 27th. They're just a hair higher today, thus officially at 6-week highs.  Whereas yesterday's Consumer Price Index (CPI) didn't have an obviously negative impact on rates, today's Producer Price Index (PPI) did. Both are big inflation reports. CPI is typically much more likely to cause a reaction in rates, but PPI showed a much bigger surge in inflation this morning. Even then, the underlying bond market wasn't too much worse by the end of the day and the mortgage-specific bond market actually made a full recovery. But that recovery was too gradual and shallow for the average lender to adjust their rates today. That left our rate index 0.01% higher day over day at 6.57% for a top tier 30yr fixed.

When the Iran war was in its initial escalation phase, the initial surge in markets took the top-tier 30yr fixed rate to 6.64% for the average lender by March 27th. Rates moved more than 0.30% lower by mid April as peace prospect improved.  The third phase of rate movement began in late April and has generally involved a jump back up toward 6.5% with the first 2 days of the present week accounting for a move from 6.42% to 6.56%. That matches the highest level seen since March 27th. Bonds yields (which underlie rates) have followed longer-term oil prices to their highest recent levels as Trump said the U.S. is not in a hurry to end the war.  [thirtyyearmortgagerates]

Last week was decidedly stronger for mortgage rates as they either held steady or moved lower on 5 out of 5 days. All told, it was a 0.14% drop from the previous week in terms of the average top-tier 30yr fixed rate.  The new week is starting out in opposite fashion with rates moving up 0.07% today alone. This follows news over the weekend that Trump rejected Iran's counterproposal to end the war. In general, the longer the war continues, the higher oil prices will remain.  Oil price don't dictate rates, but there's currently a lot of correlation due to inflation implications. Oil naturally impacts the cost to ship goods, so a rapid spike in oil prices increases inflation. Rates are based on bonds, and bonds hate inflation. In fact, inflation is technically a component of bond yields (aka "rates"). Despite the rocky start to the week, we're not necessarily destined to move in one direction or the other. Everything depends on progress toward peace, or lack thereof. To a lesser extent, this week's incoming economic data can also have an impact. Coincidentally, much of that data focuses on inflation for the month of April.

It ended up being a decent round trip for rates this week. Monday kicked things off with a jump to the highest level in more than a month, and the third highest since August 2025. But that ended up being the only day where rates went higher.  Wednesday brough the biggest chunk of the recovery with MND's daily rate index dropping 0.10%.  Tuesday and Friday (today) each added a 0.02% drop, taking the index to 6.42% after ending last week at 6.44%. War-related headlines were less of a factor today and volatility was unsurprisingly lighter as a result. This is an adjustment for seasoned rate watchers who are used to monthly jobs report being a distinct source of volatility. It's especially notable that the job count came in significantly higher with no ill effect on bonds/rates. Over the past 6 months, markets have shifted their jobs report focus from the payroll count to the unemployment rate, reversing decades of precedent. Today's outcome is more logical in that context as the unemployment rate was right in line with expectations at 4.3%.

The day began on a fairly hopeful note for the mortgage market. During overnight trading hours, the bond market improved following a report regarding a peace framework sent to Iran by The U.S.  When bonds improve, rates fall, all else equal. The gains were modest, but they allowed the average lender to set their first rates of the day at slightly lower levels compared to yesterday. Lenders prefer a "one and done" strategy when it comes to setting mortgage rates for the day, but they will make mid-day changes if the underlying market moves enough. The underlying market began moving more than enough just before the noon hour. Most lenders were forced to recall their initial rate offerings and make upward adjustments. The net effect at the time of printing is that the average lender is back in line with yesterday's levels.
