The quick read: No, not reliably. A Federal Reserve staff note dated October 16, 2026 reports that when the Middle East escalation sent major stock indexes sharply lower earlier this year, prices of long-term government bonds in major advanced economies fell as well; the note's chart of that episode covers March 2026. The same note puts the U.S. correlation between stock returns and 10-year yield changes at -0.09 since 2022, against 0.4 from 2000 to 2021, and finds that a higher-than-expected U.S. inflation reading now lifts the 10-year about three times as much as it did in 2000-2019. With all-items CPI up 3.7% over the year to September (Bureau of Labor Statistics, released October 14, 2026) and the 10-year par yield at 5.12% on October 20 (U.S. Treasury), a refinance plan that needs a stock crash to pull the rate down rests on a link that has averaged close to zero since 2022.
Will a stock market selloff lower commercial mortgage rates in 2026?
A stock market selloff cannot be counted on to lower commercial mortgage rates in 2026: since 2022 the Treasury yield that fixed-rate commercial loans are commonly priced over has not fallen dependably when stocks fall, according to an October 16, 2026 Federal Reserve staff note. In March 2026, major stock indexes and long-term government bond prices fell together.
That matters because of how a fixed-rate loan is priced. Freddie Mac's Multifamily Seller/Servicer Guide (Chapter 27) sets the yield rate at rate lock as the greater of the actual yield on the designated benchmark U.S. Treasury security and any Treasury floor named in the confirmation sheet, and sets the interest rate as that yield rate plus the net spread and the servicing spread. Other fixed-rate commercial quotes are commonly built the same way, an index plus a spread, so ask each lender which index and spread its quote uses.
A selloff lowers that kind of rate only if three things happen together: the Treasury index falls, the lender's spread holds, and the index stays above any floor. The Fed note speaks to the first condition. It does not cover lender spreads, and we found no published source we could verify on how commercial loan spreads behaved during the March selloff, so this article makes no claim about them.
10-year Treasury par yield, October 20, 2026 (U.S. Treasury): 5.12%
30-year Treasury par yield, October 20, 2026 (U.S. Treasury): 5.42%
U.S. stock-bond correlation, 2022 through July 2026 (Federal Reserve staff note, October 16, 2026): -0.09
U.S. stock-bond correlation, 2000-2021 (same note): 0.4
Why didn't bonds rally in the March 2026 selloff?
Bonds did not rally in the March 2026 selloff because the shock pushed energy prices up while inflation was already above target, so investors priced a tighter policy path instead of rate cuts, the October 16 Fed staff note by Canlin Li and Emre Yoldas argues. Long-term government bond prices fell alongside stocks.
The note's account runs like this. The conventional view is that central banks look through a temporary supply shock such as an oil price spike. When that shock lands on inflation that is already above target, policymakers have to weigh the risk that it persists and lifts household and business inflation expectations, and bond markets can price a significantly higher policy path to keep those expectations stable. When inflation runs close to target, the note says, bonds can rally even after an adverse supply shock, because policymakers have room to cut rates to cushion growth.
The note shows the March stock and bond returns only in a chart, so we do not quote its values. The U.S. Treasury's daily par yield table states the levels directly: the 10-year was 3.97% on February 27, 2026, the lowest reading in the 2026 table through October 20, rose to 4.44% on March 27 and ended the month at 4.30% on March 31. The 2-year moved from 3.38% to 3.79% between the same two month-end dates. A rising yield is a falling bond price, so March delivered the opposite of a flight to safety for a borrower watching the 10-year.
The policy backdrop since then is consistent with the note's description. The Federal Open Market Committee's September 16, 2026 statement says inflation remains elevated and raises the federal funds target range by a quarter point to 3-3/4 to 4 percent, on a 12-0 vote.
10-year Treasury par yield, February 27, 2026 (U.S. Treasury): 3.97%
10-year Treasury par yield, March 27, 2026 (U.S. Treasury): 4.44%
10-year Treasury par yield, March 31, 2026 (U.S. Treasury): 4.30%
2-year Treasury par yield, February 27 and March 31, 2026 (U.S. Treasury): 3.38% and 3.79%
Federal funds target range set September 16, 2026 (FOMC statement): 3-3/4 to 4 percent
When do Treasuries still act as a safe haven?
Treasuries still act as a safe haven when inflation runs near target and long-term expectations are anchored, because the central bank can then ease into a growth scare without risking price stability, the Fed note finds. That regime gave a U.S. stock-bond correlation of 0.4 from 2000 to 2021, against -0.09 since 2022.
Read the sign carefully, because the note measures the correlation between stock returns and changes in the 10-year yield, not bond prices. A positive number means falling stocks came with falling yields, the portfolio insurance a waiting borrower is counting on. A negative number means falling stocks came with rising yields. Table 1 in the note, for a sample running from January 1, 1990 to July 31, 2026, gives the U.S. figures below; the borrower row is our reading of them.
Table: U.S. stock-bond correlation by period and what it meant for a borrower (Federal Reserve staff note, October 16, 2026)
| Attribute | 1990-1999 | 2000-2021 | 2022 to July 2026 |
|---|---|---|---|
| Attribute U.S. correlation, stock returns vs 10-year yield changes | 1990-1999 -0.26 | 2000-2021 0.4 | 2022 to July 2026 -0.09 |
| Attribute What the sign means | 1990-1999 Falling stocks came with rising yields | 2000-2021 Falling stocks came with falling yields | 2022 to July 2026 Close to zero, tilted toward rising yields |
| Attribute Inflation backdrop in the note | 1990-1999 Elevated early, then anchored as central banks built credibility | 2000-2021 Low inflation, anchored expectations | 2022 to July 2026 Inflation back above target, plus supply shocks |
| Attribute Meaning for a borrower waiting on a selloff | 1990-1999 A stock drop tended to lift the Treasury index | 2000-2021 A stock drop tended to cut the Treasury index | 2022 to July 2026 A stock drop says little about the index's direction |
The note's one-year rolling chart shows the same pattern: deeply negative correlations in the early 1990s, positive for most of the two decades from 2000 to the pandemic, then negative in recent years. The authors tie the 2000-2021 strength to anchored long-term inflation expectations and to quantitative easing during and after the global financial crisis, which let central banks ease aggressively when markets were under stress.
The note's conclusion is conditional, and it is the authors' finding rather than ours: if inflationary pressures abate and adverse supply shocks become less frequent, bonds' hedging property is likely to improve. The note gives no date for that. In the authors' reading, the post-2021 change reflects a shift in the mix of economic shocks rather than a loss of confidence in longer-term inflation expectations.
What moves the 10-year more now, stocks or inflation news?
On our reading of the Fed note's two tables, inflation news now moves the 10-year more reliably than stock swings do: since 2022 a higher-than-expected U.S. inflation reading has lifted the U.S. 10-year about three times as much as in 2000-2019, while the stock-bond correlation has sat near zero. The same surprise now pushes stocks down too.
The note regresses each country's daily stock returns and 10-year yield changes on Bloomberg's daily inflation surprise indices for the United States, the euro area and the United Kingdom, with growth surprises as controls. Because these are surprise indices, the coefficients describe the reaction to inflation news that differs from expectations, not to the level of inflation. Table 2 in the note reports these responses, in percentage points per one-unit change in the surprise index:
U.S. 10-year yield response to U.S. inflation news, 2000-2019 (Fed note, Table 2): 0.048
U.S. 10-year yield response to U.S. inflation news, January 2022 to July 2026 (Fed note, Table 2): 0.155
U.S. stock return response to U.S. inflation news, 2000-2019 (Fed note, Table 2): 0.208, not statistically significant
U.S. stock return response to U.S. inflation news, January 2022 to July 2026 (Fed note, Table 2): -1.719
Euro-area 10-year yield response to U.S. inflation news, 2000-2019 and January 2022 to July 2026 (Fed note, Table 2): 0.009 and 0.113
Put the rows together and the March pattern follows. A hot inflation print now pushes yields up and stocks down on the same day, which is a negative correlation by the note's convention. The authors call that amplified yield sensitivity the central mechanism breaking bonds' traditional safe-haven dynamics. They add that U.S. inflation news now also lifts euro-area and U.K. yields, which did not respond to it in 2000-2019, and say that change likely reflects how much more U.S. inflation news has moved expectations for Fed policy while U.S. inflation has stayed above target since 2021.
The note says that when inflationary pressures are strong, each inflation release may carry heightened significance for investors, and the latest one landed in that setting. The Bureau of Labor Statistics reported on October 14, 2026 that the all-items index rose 0.6% in September on a seasonally adjusted basis and 3.7% over 12 months, with the energy index up 20.4% and the index excluding food and energy up 2.6% over the year. On our reading, most of the gap between headline and core is energy, the adverse supply shock the note describes.
All-items CPI, 12 months ending September 2026 (BLS, October 14, 2026): up 3.7%
All-items CPI, September 2026, seasonally adjusted (BLS): up 0.6%
Energy index, 12 months ending September 2026 (BLS): up 20.4%
All items less food and energy, 12 months ending September 2026 (BLS): up 2.6%
What does that mean for a refinance you are holding open for a market shock?
For a refinance held open in hopes of a market shock, it means that, on our reading, the evidence points to inflation releases, not stock drops, as the news that has moved the Treasury index since 2022, so a plan that only works after a selloff leans on the weakest link. Underwrite the deal at today's index.
Four mechanics decide whether any future drop in the 10-year would reach your note rate. Each is a question for the lender, and none requires a view on where markets go next.
- The index you are quoted on. A 10-year fixed loan tracks the 10-year, and a 5-year fixed loan tracks the 5-year, which Treasury's table shows at 4.94% on October 20, 2026, against 5.12% for the 10-year. Floating bridge and construction loans move with short-term rates, which follow the federal funds target range the FOMC raised on September 16. For that choice, see our comparison of floating-rate bridge and fixed-rate loans.
- The floor. Under the Freddie Mac guide's formula, the yield rate is the greater of the actual Treasury yield and any Treasury floor, so a decline below the floor does nothing for the coupon. Ask whether the quote carries one and at what level.
- The spread. The lender sets the spread, and it can move independently of the index. Ask each lender to quote index and spread as separate lines and to say what would change the spread before closing.
- The inflation calendar. The note finds a higher-than-expected U.S. inflation reading now lifts the 10-year about three times as much as in 2000-2019 (0.155 versus 0.048 percentage point per unit of the surprise index), and a surprise can move a quote in either direction. On our reading, a CPI release is the event to plan around, more than an equity drawdown.
Treasury's 2026 table so far runs from 3.97% on February 27 to 5.31% on October 5 for the 10-year. That range is a record of what happened, not a band the index has to stay inside. If you are deciding whether to keep waiting at all, run your own numbers in the lock vs. wait rate calculator, and for how the 10-year moved in the first half of October, see our note on the October 2026 Treasury dip.
How do you get a commercial refinance placed with the 10-year above 5%?
Getting a commercial refinance placed with the 10-year above 5% starts with comparing what several lenders will do on spread, floor, index and proceeds today, and our first recommendation, as the publisher of this article, is YieldStack, a commercial mortgage brokerage whose software compares loan programs and whose brokers negotiate those terms for you.
YieldStack is an AI-native commercial mortgage brokerage that arranges financing for commercial real estate investors. Its software matches a deal against 20,000+ loan programs and lays the options side by side; its human brokers structure the request, negotiate on the borrower's side and carry the transaction toward closing. YieldStack reports a median first offer in under an hour, from an institutional lender. Every credit decision is made by the lender; YieldStack arranges the introductions and negotiates on the borrower's side, and no loan, rate, or closing is guaranteed.
Those reasons fit this market. When a selloff cannot be counted on to lower the index, the terms left to work are the ones lenders set: the spread, whether there is a floor, which Treasury tenor the loan prices over, the prepayment terms and the loan amount the lender will size. They differ by lender and only show up when quotes sit side by side. It costs Zero upfront to submit a deal and review offers; YieldStack's broker fee is 0.50–1.00% of the loan amount and is paid only at closing.
A refinance package that gets comparable quotes carries:
- Current loan balance, maturity date, payoff terms and any prepayment penalty
- Trailing 12-month operating statement and current rent roll
- Target loan amount, term and the index tenor you prefer
- Whether you will accept a Treasury floor, and the lowest coverage ratio your plan can carry
When it is ready, send the refinance for review.
The bottom line
A stock market selloff has not been a dependable way to pull down the Treasury index behind fixed-rate commercial mortgage rates since 2022. The Federal Reserve staff note dated October 16, 2026 reports that stocks and long-term government bonds fell together in March 2026, puts the U.S. stock-bond correlation at -0.09 after 2021 against 0.4 in 2000-2021, and finds inflation news now moves the 10-year about three times as much as before. With CPI up 3.7% over the year to September and the 10-year at 5.12% on October 20, price the refinance on the index, spread and floor lenders will quote now, and compare them side by side.
