What a bond yield is
A Treasury pays a fixed interest rate until it matures. When newly issued bonds pay more, older ones lose value: yield and price move in opposite directions. The 10-year yield was 4.19% on 2 January 2026 (U.S. Treasury). By our own calculation, a $1,000 ten-year Treasury bought that day was worth about $919 at the 5.31% yield of 5 October – a loss of about 8% on the safest investment in the world.
How it got here
In late February 2026 the yield dipped to 3.97% (U.S. Treasury). Brent crude averaged about $71 a barrel in February and about $117 in September (World Bank, Pink Sheet). US consumer prices were 2.4% higher than a year earlier in February, 4.3% in May and 3.7% in September (U.S. Bureau of Labor Statistics, CPI). On 16 September 2026 the Federal Reserve raised its target range by a quarter point to 3.75–4.00%, by a vote of twelve to zero (FOMC statement). Between 22 and 24 September the 10-year yield rose from 4.96% to 5.18% (U.S. Treasury).
Three forces
Inflation: when prices rise by almost 4% a year, a bond paying 4% earns nothing in real terms. The Fed: the two-year yield rose from 3.47% in January to 4.74% in mid-October, and a three-month bill paid 4.26% (U.S. Treasury). Supply: in fiscal 2026 the government spent about $2 trillion more than it took in (U.S. Treasury, Monthly Treasury Statement), and total federal debt was $40.39 trillion on 15 October 2026 (Debt to the Penny) – every dollar of the deficit has to be borrowed by selling bonds.
Who pays
The government first: in fiscal 2026 net interest was $1.05 trillion and national defense $965 billion (U.S. Treasury, Monthly Treasury Statement, September 2026). The average interest rate on marketable debt rose from 1.42% in January 2022 to 3.52% in September 2026 (U.S. Treasury), and it keeps rising as old debt is refinanced at today’s rates. Households next: lenders price long-term home loans off long-term Treasury yields, so new mortgages follow the 10-year yield. The average 30-year fixed mortgage rate was 7.40% on 15 October 2026 (Freddie Mac, Primary Mortgage Market Survey®). Credit card accounts charged interest at more than 22% in August 2026 (Federal Reserve, G.19).
Who gets paid
Higher yields move money from borrowers to lenders. A three-month Treasury bill paid about 4.26% in mid-October (U.S. Treasury), while the national average savings rate was 0.37% (FDIC). The yield eased to 5.09% on 16 October (U.S. Treasury). What happens next depends on three things to watch: the monthly inflation figures, the Fed’s decisions and the results of Treasury auctions.

Frequently asked questions
What is the 10-year Treasury yield?
The interest rate the US government pays to borrow for ten years. It reached 5.31% on 5 October 2026, the highest since May 2002 (U.S. Treasury, Daily Treasury Par Yield Curve Rates).
Why did Treasury yields rise in 2026?
Inflation rose to 3.7% in September (BLS), the Fed raised its target range to 3.75–4.00% on 16 September (FOMC), and the government had to sell more bonds to finance a deficit of about $2 trillion in fiscal 2026 (Monthly Treasury Statement).
Why do bond prices fall when yields rise?
A bond pays a fixed rate. When new bonds pay more, buyers will only take an older bond at a discount – so its price falls as yields rise.
How do Treasury yields affect mortgage rates?
The 10-year yield is the anchor for US mortgages: lenders price long-term home loans off long-term Treasury yields, so when the 10-year yield rises, new mortgages usually get more expensive. On 15 October 2026 the average 30-year fixed mortgage rate was 7.40% (Freddie Mac, Primary Mortgage Market Survey®).
