The Treasury Department sold $58 billion of three-year notes on Tuesday, August 11, at a high yield of 4.291 percent, the most the federal government has paid at a three-year auction since February 2025. Bidders submitted $157.3 billion in orders excluding the Federal Reserve’s rollover, a bid-to-cover ratio of 2.71 that was the strongest since November 2025. The sale opened the Treasury’s quarterly refunding, a three-day sequence that continues with $42 billion of 10-year notes on Wednesday afternoon and $25 billion of 30-year bonds on Thursday, $125 billion in all. Indirect bidders, the category that captures foreign central banks and other overseas accounts, were awarded $36.87 billion of the $57.4 billion sold on competitive bids, or 64.2 percent. Primary dealers, the firms obligated to absorb whatever the public will not, were left with 11.7 percent. The combination is uncommon. Investors demanded the highest three-year yield in 18 months and still showed up in size. For households, the result is a read on the price the government pays to carry a debt load that reached $39.89 trillion on August 10, and on the medium-term rates that filter into car loans and refinancing offers. It is not a read on the prime rate, which banks set off the Fed’s target range and which stands at 6.75 percent.
- Treasury sold $58 billion of three-year notes on August 11 at a 4.291 percent high yield.
- That is the highest yield at a three-year note auction since February 2025.
- Bid-to-cover came in at 2.71, the strongest reading since November 2025.
- Indirect bidders took 64.2 percent of competitive awards and dealers were left 11.7 percent.
- The prime rate holds at 6.75 percent. The Fed next decides September 16.
What the Auction Showed
The note carries a 4.250 percent coupon and was awarded at a price of 99.885444, slightly below par, which is what lifts the yield above the coupon. Treasury received $171.97 billion in total bids, $157.3 billion of that from outside the Federal Reserve, against the $58 billion offered to public bidders. Competitive bids alone totaled $156.7 billion, and $57.4 billion of them were accepted. The median accepted yield was 4.243 percent and the lowest was 3.880 percent, a spread wide enough to show how far apart investors sit on three-year money. Treasury allotted 18.31 percent of bids submitted at the high yield, so the sale cleared with room left in the book.
The breakdown of who bought ran in an investor-friendly direction. Indirect bidders were awarded $36.87 billion, 64.2 percent of the competitive total, above the 63.2 percent they averaged across the first seven three-year sales of 2026. Direct bidders, mostly domestic institutions buying for their own accounts, took 24.0 percent. That left primary dealers with $6.74 billion, or 11.7 percent, up from 7.7 percent in July but far below the shares they carried in the spring. Dealers function as the buyer of last resort, so a modest dealer share signals that end investors absorbed the paper. The Federal Reserve added $14.67 billion for its System Open Market Account, rolling maturing holdings into the new issue. The notes settle August 17 and mature August 15, 2029.
Why a High Yield and Strong Demand Arrived Together
The two facts look contradictory only if you assume buyers choose the yield. They do not. The yield is the level an auction has to reach before enough money appears, and this month it had to reach further than at any three-year sale since February 11, 2025, when the note stopped at 4.300 percent. Between those two auctions the three-year cleared as low as 3.485 percent, in September 2025. The climb back up reflects a Federal Open Market Committee that has stopped cutting. The Committee held its target range at 3.50 to 3.75 percent on July 29 and does not meet again until September 15 and 16.
Secondary market yields moved the same way. The three-year constant maturity yield finished at 4.31 percent on August 10, the two-year at 4.25 percent, the 10-year at 4.72 percent and the 30-year at 5.25 percent. The 10-year sits within three basis points of its 2026 high of 4.75 percent, set on July 31. When the entire Treasury yield curve shifts higher, an auction that clears at a higher yield is not a weak auction. It is a repriced one. What separates the two is participation, and participation improved: 2.71 bids for every dollar awarded, against 2.60 in July and 2.64 in June.
What the Higher Yield Costs Taxpayers
The 4.250 percent coupon on the $58 billion sold to public bidders costs roughly $2.47 billion a year, about $7.4 billion across the note’s three-year life. Set that against July’s three-year sale, which stopped at 4.179 percent. The 11.2 basis point difference is worth about $65 million a year on the same size. Measured against February’s auction, which cleared at 3.518 percent, the gap widens to 77.3 basis points, or roughly $448 million a year. Those are single-auction figures, and Treasury runs this cycle every month across every maturity on the calendar.
The cumulative effect shows up in Treasury’s own accounting. The average interest rate on all interest-bearing federal debt reached 3.447 percent on July 31, up from 3.409 percent a month earlier and higher in each of the past four monthly readings. Interest expense on the public debt totaled $1.17 trillion in the first 10 months of fiscal 2026, including $117.6 billion in July alone. Total debt outstanding stood at $39.89 trillion on August 10, of which $32.14 trillion is held by the public and $7.75 trillion by government accounts. That leaves the federal debt about $108 billion below the $40 trillion mark.
What This Means for Your Money
Nothing about a Treasury auction changes your credit card rate this week. Large banks set the prime rate 3 percentage points above the top of the Fed’s target range, which puts it at 6.75 percent, and the H.15 release shows it unchanged on each of the five most recent business days. Card balances and home equity lines follow prime, so they reprice only when the Committee moves. If you want the mechanics, our explainer on how the Fed affects your loans walks through each step from the target range to your statement.
The three-year and 10-year sections of the curve are a different matter. Auto lenders and personal loan issuers fund at medium-term maturities, so a three-year note stopping at 4.291 percent instead of 3.518 percent works its way into quoted offers within weeks. Mortgage rates track the 10-year, which closed at 4.72 percent on August 10. Savers sit on the other side of the same trade. Deposit products priced off Treasury yields, including certificates of deposit and high-yield savings accounts, tend to hold their posted rates while the curve stays elevated, which is the practical reason to lock a term now rather than wait.
If you are shopping a three to five year loan, measure the quote against the 4.291 percent the federal government just paid to borrow for three years. That figure is close to a floor for what any private borrower pays, because Treasury debt carries no credit risk. A personal loan quoted at 11 percent is charging you about 6.7 percentage points for your credit profile and the lender’s margin. Knowing that gap tells you whether an offer is competitive.
Frequently Asked Questions
What were the results of the August 2026 three-year Treasury note auction?
Treasury sold $58 billion of three-year notes on August 11, 2026 at a high yield of 4.291 percent, with a bid-to-cover ratio of 2.71. Indirect bidders took 64.2 percent of competitive awards, direct bidders 24.0 percent and primary dealers 11.7 percent. The notes carry a 4.250 percent coupon and mature on August 15, 2029.
Is it good if Treasury yields go up?
It depends which side of the transaction you are on. Higher yields mean savers earn more on Treasury bills and notes, certificates of deposit and money market funds. They also mean the federal government pays more to borrow, which is why interest expense on the public debt reached $1.17 trillion in the first 10 months of fiscal 2026. For borrowers, higher Treasury yields raise the cost of mortgages, auto loans and business credit, because lenders price those products off government yields plus a spread. No single answer fits every household.
Who benefits when Treasury yields are high?
Savers and income investors benefit most directly. Someone who bought at the August 11 auction locked in 4.291 percent for three years with no credit risk. Banks and insurers that run large bond portfolios earn more on new purchases, although they carry losses on bonds bought at lower yields. Foreign buyers benefit when a higher yield arrives alongside a stable dollar, which helps explain why indirect bidders took 64.2 percent of this sale. Borrowers and the Treasury itself sit on the losing side of the same move.
Does a Treasury auction change the prime rate?
No. Large commercial banks set the prime rate at 3 percentage points above the top of the federal funds target range, so it moves only when the Federal Open Market Committee changes that range. The Committee held at 3.50 to 3.75 percent on July 29, which keeps prime at 6.75 percent. A Treasury auction reveals what investors charge the government to borrow at one specific maturity. The two rates answer to related forces, but an auction result never mechanically resets your credit card rate.
How does the three-year note affect my car loan or mortgage?
Auto lenders and personal loan issuers fund themselves at medium-term maturities, so the three-year Treasury yield sits close to their raw cost of money. When that yield climbs from 3.518 percent in February to 4.291 percent in August, the floor under new loan offers rises with it. Mortgages track the 10-year Treasury instead, which closed at 4.72 percent on August 10, within three basis points of its 2026 high. Neither move touches an existing fixed-rate loan. Both change the number you are quoted on a new one.
When is the next Treasury auction and the next Fed decision?
Treasury sells $42 billion of 10-year notes on Wednesday, August 12 at 1 p.m. Eastern and $25 billion of 30-year bonds on Thursday, August 13, completing a $125 billion quarterly refunding. The Federal Open Market Committee next meets September 15 and 16, and that meeting carries a Summary of Economic Projections. Before then, the July Consumer Price Index is released Wednesday, August 12 at 8:30 a.m. Eastern, and minutes from the July meeting are due around August 19.
Watching the Long End Before September 16
Two more auctions this week will show whether the appetite that met the three-year holds at longer maturities, where duration risk is larger. The 10-year prices Wednesday afternoon and the 30-year on Thursday. July inflation data lands the same morning, and the Committee’s next decision is five weeks out.
