The 30-year Treasury yield closed at 5.47 percent on Wednesday, September 24, the highest level for the long bond since June 28, 2004, according to the Federal Reserve’s H.15 release. The 10-year note finished the same session at 5.18 percent, its highest close since July 6, 2007. Both marks capped a three-session selloff that added 18 basis points to the 30-year yield and 22 basis points to the 10-year, and both arrived eight days after the Federal Open Market Committee raised its target range and pushed the bank prime loan rate to 7.00 percent. The move was not a bet on faster inflation. The 10-year breakeven rate, which measures what the market expects inflation to average over the coming decade, sat at 2.33 percent on September 24, exactly where it sat on September 22 before the selloff began. Every basis point of the 10-year increase came out of the real yield, the inflation-adjusted return investors demand for parking money in government paper. Treasury sold $183 billion of two-year, five-year and seven-year notes across those same three days. The long end of the Treasury yield curve prices 30-year mortgages, corporate debt and the government’s own refinancing, so 5.47 percent reaches far beyond the bond market. It also lifts what Washington pays in interest on the national debt.

What the H.15 Release Shows
The Federal Reserve publishes constant maturity Treasury yields every business day in its H.15 release, and the September 25 edition records the week in five rows. The 30-year yield sat at 5.29 percent on Monday and again on Tuesday, jumped to 5.40 percent on Wednesday and settled at 5.47 percent on Thursday. The 10-year followed the same path, moving from 4.96 percent to 5.11 percent and then to 5.18 percent. The two-year rose more slowly, from 4.71 percent to 4.87 percent, steepening the two-year to 10-year gap to 31 basis points by Thursday and 36 by Friday.
The same release shows the policy rate anchored in place. The effective federal funds rate held at 3.88 percent every day of the week, and the bank prime loan rate held at 7.00 percent, where banks moved it on September 17 after the FOMC decision the day before. Three-month bill yields drifted up to 4.08 percent. Short rates answered what the Fed already did. Long rates answered something the Fed has not done yet. The five-year closed at 5.03 percent and the seven-year at 5.10 percent, so the belly moved nearly as much as the long end.
How the Selloff Built Across Three Sessions
Monday and Tuesday were quiet. The 30-year held at 5.29 percent and the 10-year at 4.96 percent while Treasury auctioned $69 billion of two-year notes at a high yield of 4.787 percent, drawing bids worth 2.63 times the offering. Wednesday broke the calm. Early September purchasing manager surveys landed showing activity that JPMorgan economists described as consistent with a 5 percent annual run rate for gross domestic product, and the same surveys showed the prices those companies paid climbing sharply. Yields jumped 11 basis points on the 30-year and 15 on the 10-year that day, the largest single-session move in the 10-year since April 2025. Treasury sold $70 billion of five-year notes into it at 5.033 percent, with a bid-to-cover ratio of 2.21.
Thursday extended the move rather than reversing it. Treasury cleared $44 billion of seven-year notes at a high yield of 5.085 percent, covered 2.42 times, which brought the week’s coupon supply to $183 billion. The 30-year finished at 5.47 percent and the 10-year at 5.18 percent. Money market pricing shifted with it, and traders assigned better than even odds to quarter-point increases at both the October and December FOMC meetings, according to reporting from Axios. Friday brought no relief.
Real Yields, Not Inflation Bets, Carried the Move
A nominal Treasury yield contains two pieces: the real yield investors require after inflation, and the compensation they demand for the inflation they expect. Treasury inflation-protected securities let the market separate them. The 10-year TIPS real yield stood at 2.63 percent on September 22. By September 24 it reached 2.85 percent, a rise of 22 basis points. The 10-year nominal yield rose by exactly the same 22 basis points over those two sessions. The 10-year breakeven rate, the difference between the two, finished at 2.33 percent on both days. Investors did not raise their inflation forecast at all. They raised the price of lending to the government.
The 30-year told the same story. Its real yield climbed from 3.04 percent to 3.21 percent while the nominal yield added 18 basis points, leaving roughly one basis point attributable to inflation expectations. Supply and the Federal Reserve’s shrinking footprint sit behind that repricing. The September 24 H.4.1 release put Fed total assets at $6.75 trillion, holding $4.56 trillion of Treasuries and $1.91 trillion of mortgage-backed securities, with reserve balances down $83.6 billion in one week to $2.93 trillion. Treasury debt outstanding reached $40.07 trillion, and the average rate the government pays on interest-bearing debt hit 3.490 percent in August, up from 3.447 percent in July.
What a 5.47 Percent Long Bond Means for Your Money
Mortgage pricing moved first. Freddie Mac’s 30-year fixed average reached 7.03 percent in the week ended September 24, up from 6.76 percent two weeks earlier and the highest weekly reading since January 16, 2025. Lenders price home loans off the 10-year Treasury plus a spread, so a 22 basis point jump in the benchmark reaches borrowers within days. On a $400,000 loan, the difference between 6.76 percent and 7.03 percent is about $72 a month, or roughly $26,000 across the full term. Anyone shopping a purchase or refinance should compare current mortgage rates before a rate lock expires.
Variable consumer borrowing follows a different track. Credit card APRs, home equity lines and most variable personal loans reset off the prime rate, which banks peg at 3 percentage points above the upper bound of the federal funds target. Prime has held at 7.00 percent since September 17 and will not move again until the FOMC acts. The deposit side improves in the meantime. Banks and credit unions reprice certificates of deposit and high-yield savings accounts against the same Treasury curve that just steepened, so longer-dated CD offers are the first place a 5.47 percent long bond shows up as income rather than cost. The mechanics of that transmission are laid out in our guide to how Fed decisions affect loans.
Pro Tip
If you are carrying a variable-rate balance, the window between FOMC meetings is the cheapest time to act. Prime is fixed at 7.00 percent until at least October 28, so a fixed-rate consolidation loan quoted this month locks a known cost before any further increase. On the savings side, ladder your CDs instead of committing everything to one maturity. A steeper curve rewards the longer rungs, and a ladder keeps cash reaching you every few months if yields keep climbing.
Frequently Asked Questions
Why did the 30-year Treasury yield rise to 5.47 percent?
The 30-year Treasury yield closed at 5.47 percent on September 24, 2026, its highest level since June 2004, after strong September business surveys and $183 billion of new note supply pushed investors to demand a higher real return. Inflation expectations did not move.
Why is the US bond market selling off?
Three forces are pulling in the same direction. Growth data came in hotter than expected in early September, which raised the odds that the Federal Reserve hikes again in October or December. Treasury is issuing heavily, with $183 billion of coupon supply in a single week and $40.07 trillion of debt outstanding. And the Fed is still letting its balance sheet run down, which removes a buyer. The result is a higher real yield rather than a higher inflation premium, which is visible in breakeven rates that have not budged.
How high will the 30-year Treasury yield go?
Nobody can forecast a yield reliably, but the reference points are worth knowing. The last time the 30-year traded above current levels was June 2004, when it reached 5.49 percent. Before the 2008 financial crisis the long bond spent most of the prior decade between 5 and 7 percent. Whether yields continue higher depends mainly on two things: whether the FOMC raises rates at its October 27 and 28 meeting, and whether Treasury increases auction sizes at its next quarterly refunding. Watch the Fed meeting schedule for the decision dates.
Is now a good time to buy 30-year Treasury bonds?
That depends on your time horizon and your tolerance for price swings, and this is information rather than investment advice. A 30-year bond bought at 5.47 percent locks that coupon for three decades, and the 30-year TIPS real yield of 3.21 percent means the return holds up even if inflation runs at the 2.3 percent the market expects. The risk is duration. If yields rise another full point, a long bond’s market price falls sharply, and selling before maturity realizes that loss. Holding to maturity removes price risk but not inflation risk.
Does a 5.47 percent long bond change my mortgage rate?
Indirectly, and quickly. Lenders price 30-year fixed mortgages off the 10-year Treasury rather than the 30-year bond, because most mortgages are repaid or refinanced within about a decade. The 10-year rose 22 basis points in the same stretch, and Freddie Mac’s survey average moved from 6.76 percent to 7.03 percent over two weeks. If you already have a fixed-rate mortgage, nothing changes. If you are shopping, the lock period is what protects you, and locks typically run 30 to 60 days.
What happens to my credit card and savings rates now?
Credit card APRs track the prime rate, which is 7.00 percent and will stay there until the FOMC moves again. The September 17 increase is already flowing into statements, and most issuers apply a change within one or two billing cycles. Savings rates run on a looser leash. Online banks compete against Treasury bills, which now yield 4.08 percent at three months, so the better high-yield accounts and short CDs should keep drifting up. Check the national debt total if you want the supply side of the story.
Watching the October FOMC and the Next Refunding
Three dates shape the next leg. The FOMC meets October 27 and 28, and an increase there would carry prime above 7.00 percent for the first time since 2023. Treasury announces its quarterly refunding in early November, which sets auction sizes into the new year. And the December 8 and 9 meeting arrives with a fresh Summary of Economic Projections. Track the benchmark on the Treasury yield curve, the policy path on the Fed rate forecast, and the balance sheet on the Fed balance sheet page.
