The ten-year ended where it started.
Your mortgage rose, and Massachusetts sellers are absorbing the difference.
Last month we argued that the bond market, more than the Fed, sets your mortgage rate. October tested that from the other direction. Measured over the same weeks, the ten-year Treasury is back where it was when our September issue went out, after an AI-led stock selloff on October 22 cut it 17 basis points in a day. The thirty-year mortgage is 21 basis points higher, all of it from the premium lenders charge over the ten-year, which widened in every weekly reading. Oil pushed inflation up the whole time. In Massachusetts the multifamily seller kept giving ground, and the oil-heated building got a fuel bill to match.
- The AI trade cracked in debt, then in stocks. Data-center borrowers paid junk-level yields in mid-October, and on October 22 Meta's funding plan set off a tech selloff that sent money into Treasuries.
- The mortgage rose while the Treasury went nowhere. The gap between the two widened in every weekly reading since our September issue, and about 8 basis points of the October 22 rally reached borrowers.
- Oil and the Fed still point up. Inflation rose again in September, two officials voted to hike in October, and futures price a December hike.
- Massachusetts is where it lands. Multifamily sellers are conceding in most active towns, heating oil costs far more than a year ago, and rents are holding.
One chain, from the AI selloff to your heating bill
In July we wrote that the AI boom helping to hold your rate up was also the piece most likely to break it. In October it cracked, first in the debt market and then in stocks, and only a sliver of the relief reached borrowers. Read the chain top to bottom: most of the relief stops at the Treasury, and the costs keep going down to the closing table and the operating statement.
| The link | What is actually happening | Where it hands off |
|---|---|---|
| The AI trade cracks | Data-center debt trades at junk-level yields, then Meta's funding plan sets off a tech selloff on October 22 | Money moves into Treasuries |
| Treasuries rally | The ten-year falls 17 basis points on October 22, then partly rebounds | Most of the relief stops at the Treasury |
| The mortgage premium widens | Mortgage bonds trade wide of their ten-year average, with agency and bank demand weak | The mortgage stays above 7% |
| Oil keeps inflation rising | Ship attacks in Hormuz run at a wartime high | Futures price a December hike |
| Massachusetts absorbs it | Most active multifamily towns close below ask, and oil heat costs far more | Leverage moves to buyers while operating costs move against owners |
The AI trade cracked
The AI trade cracked in debt, then in stocks
The data centers behind the AI boom are built with borrowed money, and by 24/7 Wall St.'s count nearly half of the data-center bonds sold this year carry junk ratings, a junk total more than four times last year's. In October the pressure reached the borrowers themselves. CoreWeave, which rents out AI computing capacity, saw its unsecured bonds trade near a 15% yield and its shares fall about 36% between September 30 and October 22; Bernstein estimates it must raise roughly $76 billion beyond its current facilities to deliver on signed contracts. Oracle's five-year default insurance reached a record 288 basis points on October 15. Then stocks broke. On October 22 Meta fell 7% after announcing a new class of non-voting stock it can use to raise capital while it spends heavily on AI, a plan that, in Reuters' words, "revived concern over its mounting capital commitments." The chip index fell 6.7% and the Nasdaq 2.6%. "They are rotating out of techs, out of the AIs, and into the more safety trades," Themis Trading's Joe Saluzzi told Reuters. That day the ten-year fell 17 basis points, from 5.13% to 4.96%, about half of its slide from the October 5 peak to the October 29 close. When the AI trade cracked, the money ran to Treasuries, and that lowered the ten-year for a reason that does nothing for a borrower.
Government debt repricing reached France
France's ten-year yield rose above 5% on October 21, its highest level since June 2002, as a minority government struggled to pass a budget through a divided parliament amid street protests, and its spread over German debt reached about 170 basis points, the widest since the euro debt crisis. It eased back below 5% after Moody's affirmed France's Aa3 rating on October 23, keeping a negative outlook. In September the multi-decade highs came from Japan and Germany. The repricing of government debt has moved from the largest balance sheets to the most politically fragile ones, and each of them competes with the U.S. Treasury for the same pool of global savings.
The full-year interest bill came in larger
CBO's tally for the fiscal year that ended in September puts net interest at $1,143 billion, up 11% from $1,028 billion, still larger than Medicare net of premiums at $1,069 billion and defense at $916 billion. The deficit reached $1,993 billion against $1,775 billion the year before, and customs revenue fell 11% as about $130 billion of tariffs struck down by the Supreme Court was refunded. CBO attributes the interest increase to a larger debt and higher long-term rates. October's biggest rally came from a stock selloff while the government's borrowing need kept growing, so it could reverse as quickly as it arrived, and on October 28 the ten-year closed back above 5%.
Hormuz had its worst month for shipping since the war began
October brought the most attacks on ships in the Strait of Hormuz since the war began on February 28. At least 12 vessels were attacked in the week to October 16, and oil moved through the strait at about 68% of its pre-war rate in the week to October 13. Brent futures traded at $114.87 midday on October 28, against just above $107 late on September 27, the eve of our last issue. The Wall Street Journal reported this week that Washington warned several Gulf Arab countries to prepare for a possible renewed military campaign against Iran after the November 3 midterms, while Qatari mediators handed Tehran a new draft deal, whose ideas a senior Iranian official called unacceptable on October 29, though contacts continue. Oil is the one force in this issue that pushes inflation up whatever happens to the AI trade, and in Massachusetts it reaches the operating statement first, through heating oil (§04).
China's central bank bought gold into a falling price
China's central bank added 23 tonnes of gold in September, its largest monthly purchase since October 2023 and its twenty-third straight month of buying, while the dollar price of gold fell 8.5% over the month as Treasury yields and the dollar rose. U.S. gold funds took in $11.7 billion in the third quarter after $5.6 billion of outflows from the sector in the second. We read that as the largest official buyer moving away from the dollar on a multi-year schedule and treating a falling price as an entry point.
The Fed held, and the exit narrowed
A hold, two votes to hike, and fewer decisions ahead
On October 28 the committee kept the target range at 3.75 to 4% by ten votes to two, with Lisa Cook and Beth Hammack preferring another quarter-point increase, and kept the line that inflation "remains elevated." After the meeting, futures priced a December hike above 90%, by one report, so the market expects the hike the two dissenters wanted. Chair Warsh also announced that from 2027 one of the eight annual meetings becomes a strategy session with no rate decision, rising to two in 2028. Fewer rate decisions, each with more data behind it, leave more of the work between meetings to the bond market.
The one exit narrowed in the wrong direction
Since July we have tracked the gap between the thirty-year mortgage and the ten-year Treasury as the one route by which mortgages could ease without the Fed first winning on inflation. It widened in every weekly reading. Measured against the ten-year's average over each Freddie Mac survey week, the gap went from 2.03 points at our September issue to 2.05, 2.12, 2.19, 2.20 and 2.24 across the October 1, 8, 15, 22 and 29 readings. In the October 29 survey, the first to capture the rally, the mortgage fell 8 basis points while the ten-year's survey-week average fell 12. Tom Lawler links the wider spreads on mortgage bonds to higher implied rate volatility, while noting they are not especially wide by historical standards, and Eaton Vance puts the current-coupon spread at 125 basis points at the end of September, against a ten-year average of about 111, with demand from Fannie Mae, Freddie Mac and banks weak. Our reading is that volatility is the shared mechanism: the swings that pulled the ten-year down also raised the premium on mortgage bonds, and the borrower paid for the uncertainty. Illustrative: had the gap held at 2.03, the mortgage would sit near 7.03% against the latest survey week's ten-year, about $85 a month less on a $604,000 loan.
Hiring slowed and pay fell behind prices
Employers added 29,000 jobs in September, and July and August were revised down by a combined 60,000, which leaves July negative. Unemployment was 4.2% and average hourly pay rose 3.0% over the year, below the inflation rate in §03, so real pay is shrinking. Futures expect a hike while hiring slows and real pay falls, a mix that keeps rate expectations unsettled, and unsettled rates are what widen the mortgage premium.
The reads that carry the argument
| Indicator | Current read | Signal |
|---|---|---|
| CPI, September y/y (headline / core) | 3.7% / 2.6%, against 3.4% / 2.4% in August | Rising again |
| Energy and gasoline, September y/y | +20.4% and +34.2% | Oil-led |
| 2-yr Treasury (Oct 29 close) | 4.61%, against 4.87% on Sept 24 | Still above the policy range |
| 30-yr Treasury (Oct 29 close) | 5.32%, against 5.47% on Sept 24 | Safety rally |
| Greater Boston lab vacancy, Q3 | 28.9%, up 0.2 points on the quarter; asking rents down 8.1% y/y | Local engine still soft |
Sellers conceded, heat got expensive, rents held
Start with the deal we used last month. Illustrative, not a quote: 20% down on last month's $755,000 median multifamily leaves a $604,000 loan. At the October 29 rate of 7.24% that is about $4,116 a month in principal and interest, against about $4,031 at the September 24 rate and $3,688 a year ago at 6.17%. The ten-year is back where it was over the same weeks, and this buyer's payment still rose by about $85 a month. Every housing figure below is a live MLS PIN pull taken October 28, comparing January 1 to October 27 of this year against the same window last year; job, energy and policy figures carry their own sources.
Most active multifamily towns now close below the seller's first price
Against 4,352 last year, so volume held within one percent.
Against 11. Buyers take longer to commit.
Against 98.5%, with days to offer up from 15 to 20.
The negotiation kept moving toward buyers, and it is now the typical case. Among the 40 towns with at least twenty multifamily sales in both years, the ratio of median sale price to median original asking price fell in 30, which hold 77% of this year's sales in the group, and days to offer rose in 30. In 24 of those towns the median sale now lands below the original ask, against 10 a year ago, and those 24 hold 62% of the group's sales. Our September count on the same test was 19 of 37. The largest drops came in Haverhill, from 107.5% to 99.2%, Medford from 102.3% to 94.0%, Marlborough from 107.1% to 99.4% and Holyoke from 107.0% to 99.9%; Quincy, Brockton, Malden and Fall River each fell about five or six points, to between 95.4% and 97.1%. Sixteen towns, including Springfield, Lawrence and New Bedford, still closed at or above the original ask. The town count is the measure to trust here: the concession has spread to most active markets, and recorded sale prices will show it only after the negotiation already has.
One caution on the statewide figure. Dividing the median sale by the median original ask gives 98.8% for this year against 100.8% last year, and the 2026 figure rose from 98.1% through late September because October's lower-priced sales pulled the median ask down more than the median sale. The single month from September 28 to October 27 came in at 97.3% against 98.8% a year earlier, but only seven towns had enough sales that month to test, so we do not read it as a trend.
Single family held steady; condos slowed in pace
Single-family closings slipped 1.0%, to 31,160, and the statewide ratio moved from 100.0% to 99.3%, but among the 199 towns with at least fifty sales in both years the ratio fell in 107, holding 54% of sales, so we read single family as steady. Condominium days to offer rose from 12 to 16, and rose in 81 of the 108 towns with at least thirty sales in both years; the condo ratio fell from 99.0% to 97.4% statewide, and fell in 62 of those 108 towns, which hold under half of their sales. Multifamily, the product most dependent on financing and rent math at a 7% rate, is where the concession has spread; single family is holding, and condos are slowing without a broad price give.
Heating oil is where Hormuz reaches a Massachusetts building
The state's weekly survey put heating oil at $6.23 a gallon in the week of October 26, against $3.61 a year earlier, a 73% increase; propane was $3.94 against $3.60. Nationally, EIA expects households that heat with oil, mostly in the Northeast, to "pay about 21% more for the fuel than last winter," with heating oil prices forecast to rise more than 30% and milder Northeast weather offsetting part of that; East Coast distillate stocks were 32% below their five-year average in September, while households on natural gas should spend less. Illustrative only: a building that burns 2,000 gallons in a winter would pay about $12,460 at today's price against about $7,220 at last year's, roughly $5,240 more, before any change in weather or usage. The same war that keeps futures pricing a hike is raising the cost of carrying an oil-heated triple-decker, and who pays for heat, landlord or tenant, now decides how much of it reaches your net operating income.
The white-collar slide paused for a month
Massachusetts added 3,500 jobs in September, with professional and business services up 2,400 after a first-estimate loss of 6,400 in August, and August's total was revised to a loss of 5,600 from the 7,100 first reported. The state has 16,300 more jobs than a year ago, and unemployment held at 4.3%. One month does not reverse a slide in the high-paying work behind premium rents, and the October report on November 20 will show whether September was a pause or a turn.
Rents are holding, and leasing is slower at the edges
The student and immigration changes we flagged in September have not yet shown up in agent-listed rentals. Statewide, 25,200 rentals closed through October 27 against 24,908 a year earlier, at an unchanged median of $2,950 a month, with days to offer up from 24 to 26. Across the 35 towns with at least 100 leases in both years, the median rent fell in 13, rose in 13 and held in 9. Boston moved from $3,300 to $3,350 and Cambridge from $3,500 to $3,550, though Cambridge leased about 7% fewer units. Leasing slowed in Somerville, with days to offer up from 22 to 26, and sharply in Lowell, from 31 to 42. Rent is holding while leasing slows at the edges, which supports today's income line and leaves vacancy as the assumption to stress. MLS captures only the rentals listed by agents, and the first actual count of international students arrives later this fall.
The state is adding supply at the margins
Three supply measures moved this fall. On October 22 the state launched Move-In Mass, $10 million of MassHousing financing for starter homes built with manufactured, modular and other cost-saving methods, with up to $150,000 of subsidy per affordable unit where needed, expected to support at least 20 homes in its first round. On September 18 the Supreme Judicial Court unanimously upheld the MBTA Communities Act, when nine of the 177 covered communities were out of compliance; the state has since found Marblehead compliant. And the state counts 2,084 accessory dwelling units approved since the start of 2025, 854 of them in the first half of 2026. These channels matter most to a house-hacker or a buyer of land; they are small next to the existing multifamily stock that sets the comparables on a triple-decker.
Four dates that test the thesis
Each of these resolves a claim made in this issue.
The reported timetable for a possible renewed campaign runs past Election Day, and Tehran has called Qatar's latest ideas unacceptable while keeping contacts open. Oil is the fastest route from this story to your heating bill.
Whether energy keeps lifting the headline above core. Another rising month keeps December's hike on the table.
Whether September's rebound in professional and business services was a pause or a turn for the tenants behind premium rents.
The committee decides a day before the November inflation report on December 10. The new dot plot shows how far it plans to go.
What would break the argument: a mortgage gap that narrows back toward 2.0 points as volatility fades, which would pass any fall in the ten-year through to borrowers; a durable reopening of Hormuz that pulls heating oil and gasoline down; or a Massachusetts winter in which most active multifamily towns return to closing at the original ask.
We will carry each of these into Issue 9 in November.
If you are tracking a deal, a refinance, or a development timeline, these are the points that move your math.
Price the uncertainty into the deal
Four adjustments follow from this month's data, and each one comes from the same chain.
Underwrite the rate a lender will lock
The ten-year ended where it started and the mortgage rose, so a Treasury headline tells you little about your financing. Underwrite at the rate a lender will lock today, above 7%, hold it flat for the full hold, and treat a narrowing mortgage gap as the upside case described in §02.
Ask for a seller credit and spend it on the rate
When rates swing, a rate buydown is insurance against the spread, and in most active multifamily towns sellers are already closing below their first price. Ask for the concession as a credit toward a buydown, and write the offer to the specific town's sale-to-original ratio rather than the statewide headline.
Put heat on its own line
Separate heating fuel from other utilities in the operating statement, confirm the fuel type and who pays before you write an offer, and price an oil-heated building at today's fuel cost for the whole winter. A conversion to heat pumps or gas becomes a capital item to price against that bill.
Hold rents flat and stress the lease-up
Rents are holding statewide, so underwrite them flat rather than growing them, and add time to lease where leasing is slowing, as it is in Lowell and Somerville. Check the submarket's leasing speed before its asking rents.
The ten-year went nowhere while the mortgage rose, and the difference is the price of uncertainty.
Negotiate the credit now, and price heat as its own line.
