Released October 15, 2026 by U.S. Department of the Treasury. Next release: the next business day, October 16, 2026.

The US 10-year Treasury yield closed at 5.10% on October 15, 2026, according to the U.S. Treasury's daily par yield curve rates. The yield is the yearly return on US government bonds repaid in ten years. It is the benchmark that much of the country's long-term borrowing, including mortgages, is priced from.

What changed this release

The yield fell 0.09 percentage points from its October 14, 2026 close of 5.19%. It is now 0.21 points below this year's peak close of 5.31% on October 5, 2026, the highest since May 2002, based on the U.S. Treasury's daily yield curve data. The yield first closed at 5% on September 15, 2026.

How is this number measured?

The Treasury publishes one closing yield per business day for each maturity. It is a "constant maturity" yield: the Treasury estimates what a bond repaid in exactly ten years would yield, based on prices near the end of the trading day. Market news sites sometimes quote a slightly different number, because they use a live price taken at another time of day. We use the Treasury's own close so the figure always matches the official record.

Why does the 10-year yield matter?

When the 10-year yield rises, the cost of long-term loans tends to follow. Freddie Mac's weekly survey put the average 30-year fixed mortgage rate at 7.40% in the week of October 8, 2026, the highest since November 2023, according to Freddie Mac's Primary Mortgage Market Survey.
