Long-dated Treasury yields hit multi-decade highs as mortgage rates pass 7%

The US Treasury’s daily yield curve showed the 10-year note closing at 5.18% and the 30-year bond at 5.47% on 24 September¹. The 30-year yield then topped 5.5% on Friday, exceeding 5.53%^2,3. One reading put the 10-year at 5.17% after it reached roughly 5.2% earlier in the week⁴.

Friday’s yield moves widened the gaps between short and long-term yields, with key segments such as the two-year to 10-year and the five-year affected². Accounts differ on how far back the comparison reaches: one calls these 22-year highs⁵, another a 24-year high¹, and a third describes bond yields at two-decade highs in the largest market correction in generations⁹. Long-term yields rose even as consumer sentiment data beat estimates³.

Why it matters to investors

The bond market moves over the last few weeks have pushed most risk-free interest rates north of 5%⁸. Barring a rapid reversal, that implies pain in interest-sensitive sectors such as housing, new stress on federal government finances and greater risks of financial disruption⁸. It is clearer than ever that the era of cheap borrowing and abundant capital has ended⁸.

Housing is already repricing. The US 30-year fixed mortgage rate rose to 7.49%⁶. The average mortgage rate has topped 7%, with money pressures climbing for households as bond yields rise⁷. There is an offset for savers, who have taken paper losses on existing bonds in recent weeks but can now deploy cash safely with the best prospective returns seen in decades⁸. Higher yields also reach people who do not borrow, since cash in bonds or a high-yield savings account now earns more⁷.

What to watch

The long end of the curve has moved much more dramatically than the Fed’s own rate⁵. One account attributes that to an AI-driven bond issuance wave lifting long-term term premiums, with mortgages sitting on the residential end of the same curve^5,6.

Sovereign borrowing is rising alongside it. Germany’s finance agency said on Thursday that it expects federal borrowing to hit a record €525.5 billion, as interest payments compete with surging spending demands⁹. Foreign demand for US assets has not broken so far: overseas investors piled a record $942 billion into US stocks over 12 months, the highest in 40 years, with second-quarter data underscoring the trend¹⁰. Whether that bid persists as the curve steepens is the variable to track^2,10.
