Hot inflation, then a government bond sale nobody wanted to shop

How Tuesday finished

The second-worst news for mortgage borrowers on Tuesday was a government bond sale. The worst, of course, was inflation. CNBC reported the hot October consumer price report pushed Treasury yields sharply higher, and a soft auction of new 10-year notes piled on [c1]. Translation: the Treasury put fresh inventory on the shelf and the shoppers mostly browsed. Bloomberg said stocks and bonds fell together [c4]. When nobody wants what's on the shelf, the price drops, and in bonds a lower price means a higher yield, the wrong direction for borrowers.

Our verdict: nothing since the morning talks us out of locking. The mortgage-bond fund we follow, MBB, closed Tuesday at 91.24, down 0.91%, a touch below our morning check and more than eighty-five cents a share under Monday's 92.095. That's dollars per share, not a rate. Mortgage News Daily reported its average mortgage rate posted the biggest one-day jump of a calm stretch [c2]. The fund is still up 1.95% on the month, so the cushion is dented, not gone. Our latest 10-year Treasury figure, Monday's 4.88%, predates the selloff, and the weekly survey's 7.18% is older still; different gauges on different days, and neither shows anyone's rate now.

Calls by closing window

Closing within 15 days and in 16-30 days: strong lock. The tripwire fired this morning and the close confirmed it. Short files don't have time to wait for a rebound that may never show up.

Closing in 31-45 days: cautious lock. Friday morning's producer price report is the next inflation read, and we'd rather not bet the rest of the month's cushion on a friendlier sequel.

Closing in more than 45 days: cautious float. You have time for an overshoot to fade, if it does. Keep a written lock point, and if producer prices run warm too, we lock.

Outlook

Base case: Markets keep taking the inflation report seriously, rate-hike talk holds yields up, and lenders give back more of the month's improvement.

Competing case: Tuesday overshoots, Friday's producer prices come in calm, and bonds claw back part of the damage, which is why the longest window still floats.

What would change our call: A clear rebound in mortgage bonds plus a quiet producer price report could send the 31-45 day window back to float; a warm one locks everyone.

For agents

Even the Treasury couldn't move inventory Tuesday: CNBC said a soft 10-year auction piled onto the hot inflation report [c1]. Your listings aren't the only thing sitting. The fund we follow closed down 0.91%, and Mortgage News Daily reported mortgage rates posted their biggest one-day jump of a calm stretch [c2], so buyers pre-approved last week deserve a fresh payment check before writing. Floating buyers closing within 30 days should be locking. The next date that matters is Friday morning's producer price report. And the 7.18% survey sellers keep quoting was taken last Thursday, before any of this.

For buyers

Closing within 45 days and still floating? This week's decision is simple: call us, see what the market is offering, and lock if it clears the number you'd accept without regret. Waiting for bonds to undo Tuesday's slide is a hope with no deadline. Closing later than that, you can keep floating, but Friday morning's producer price report is your checkpoint, and a warm one turns your lock point into your lock. Already locked before all this? You chose with what you knew and a payment you could live with, and that was sound.

For homeowners and sellers

Selling? Your next buyer may arrive with the same enthusiasm and a slightly smaller budget. The weekly survey's 7.18% was taken before Tuesday's selloff, and Mortgage News Daily reported rates jumped [c2], so price for the buyer walking in this week, not last week's mood. Refi-curious? Tuesday is a fair reminder that a refinance may never pay off for you; one inflation report took a real bite out of a good month. We keep comparing pricing to the market regardless, and we'll tell you straight whether the numbers ever work, including if they never do.

Closing summary

Tuesday the government held a sale and the shoppers walked. We'll be at the front of the line Friday morning when producer prices post, so you can sleep in.

Continuity

Monday we floated the middle windows with a tripwire: a hot inflation report meant lock. It ran hot, and this morning we moved to lock through 45 days. Bonds closed a little lower than at our morning check, so those calls stand.
