10-year at 4.68% as investors cite Iran conflict, tech debt supply
The Wall Street Journal’s What’s News newsletter reported Monday that yields on government bonds have reached multiyear highs in recent days. The 30-year U.S. Treasury bond topping 5.3% marked the first time that long bond has crossed that threshold since 2007.
Yields rise when bond prices fall, and the broader selloff has spanned global government debt markets. According to the Journal, investors pointed to multiple overlapping pressures. The continuing U.S.-Iran conflict has stoked inflation worries, while a deluge of tech-company bonds vying for debt-fund cash has added supply pressure on long-dated paper.
The 10-year Treasury yield — the standard benchmark for U.S. borrowing costs including mortgages and corporate debt — sat at 4.68% on August 18 per Federal Reserve Economic Data. That figure approaches the yield’s highest level since early 2025. The yield has climbed in recent days alongside the broader rout.
The 10-year real yield on Treasury Inflation-Protected Securities stood at 2.44% as of Monday. That figure represents the yield investors demand after stripping out expected inflation, an indicator of how bond traders are pricing in future price pressures.
The spread between the 10-year and 2-year Treasury yields held at 0.52 percentage points on Monday. A positive spread, where long-term yields exceed short-term ones, has typically indicated that bond markets expect continued economic growth; an inverted curve has historically preceded recessions.
Rising long-term Treasury yields generally carry broader economic implications. Mortgage rates are commonly benchmarked against the 10-year yield, and corporate and federal borrowing costs generally rise alongside it, though the Journal did not quantify those effects in its report.
The Journal noted that tech-company bond issuance has been particularly heavy, with technology firms tapping debt markets. That supply pressure competes with Treasury issuance for investor demand.
