The inflation alarm we kept testing went off for real this morning

The drill is over

For a week we've run fire drills for Tuesday's consumer price report, the government's monthly read on inflation. This morning the alarm was real. CNBC reported Treasury yields jumped after October CPI came in hotter than expected, and its headline also cited a Fed official's talk of a half-point rate hike [c1]. Stocks slid, with tech under pressure again [c2]. Inflation, apparently, does not read newsletters.

Our verdict: lock. The mortgage-bond fund we follow, MBB, read 91.27 at our mid-morning check, down 0.88%, more than three quarters of a dollar a share below Monday's close. Falling bond prices mean rising yields, the wrong direction for borrowers, and drops like this tend to push lenders toward worse pricing, though we have no confirmed reprice yet. The fund is still up 1.99% on the month, so the cushion is thinner, not gone. Our latest 10-year Treasury figure is last Friday's 4.86%, and the weekly survey read 7.18% last Thursday [c4]. Both predate this morning and measure different things on different days. They show where we started, not where anyone's rate is now.

Calls by closing window

Closing within 15 days and in 16-30 days: lock. This is the tripwire we wrote down all last week, and a plan only counts if you follow it. If pricing you can live with is still available, take it before lenders catch up with the bond market.

Closing in 31-45 days: cautious lock. You have some runway, but Friday's producer price report is the next inflation read. We'd rather not bet what's left of the month's cushion on a friendlier sequel.

Closing in more than 45 days: cautious float, down from strong float. One hot report doesn't erase a month of gains, and you have time for this spike to fade partly, if it does. Set a lock point now. If producer prices run warm too, we lock.

Outlook

Base case: Markets spend the week taking a hot inflation number seriously, rate-hike talk keeps yields elevated, and lenders hand back some of the month's improvement.

Competing case: This morning's selloff overshoots, Friday's producer prices come in calm, and bonds recover part of the damage, which is why the longest window still floats.

What would change our call: A clear rebound in mortgage bonds alongside a quiet producer price report could move the 31-45 day window back to float. Another warm inflation read would move everyone beyond 45 days to lock.

For agents

Your buyer's financing just got graded by an inflation report, and CNBC says it came back hot [c1]. Rising yields this morning knocked the mortgage-bond fund we follow down 0.88%, so expect lenders to lean toward worse pricing even before a reprice is confirmed. Floating buyers closing within 45 days should be locking, not watching. The next date that matters is Friday's producer price report. Also, the weekly survey your sellers keep quoting, 7.18% [c4], was taken last Thursday, before any of this.

For buyers

If you've been floating with a lock point, this is the morning it was written for. Closing within 45 days: call us, ask what the market is offering, and lock if it clears the number you'd accept without regret. Waiting for this morning's damage to reverse is a hope, not a plan. Closing later than that, you can keep floating, but reset your lock point today and make Friday's producer price report your deadline for deciding. Already locked? You decided with what you knew and a payment you could live with. That was sound then, and it still is.

For homeowners and sellers

Selling? Your buyer's budget may have tightened before they finished their coffee. The weekly survey's 7.18% from last Thursday [c4] predates this morning's bond selloff, so price for the buyer touring this week, not last week's mood. Refi-curious? Mornings like this are a reminder that a refinance may never pencil out for you, because one inflation report can take back weeks of progress. We keep checking pricing against the market either way, and we'll tell you plainly whether the numbers ever work, including if they don't.

Closing summary

Fire drills are boring right up until the morning the alarm is real. We'll keep an ear on Friday's producer prices so you can go back to ignoring inflation, which is all it deserves.

Continuity

Since last Friday we held cautious lock inside 15 days, cautious float for 16-45 days and strong float beyond. We said a hot inflation report would move the middle windows to lock. CNBC reports it ran hot, so we're doing what we said.
