Summary
5.34% marked the intraday peak for the 10-year Treasury on Thursday, the highest since 2002, before the yield eased later in the session and into Friday.
Iran war disruption risks in the Strait of Hormuz, wider federal deficits, tight monetary policy and heavier corporate bond issuance tied to the AI buildout all pushed longer-dated yields higher.
Mortgage, auto and student-loan rates tend to track the 10-year benchmark, and analysts said higher yields could slow housing and car sales by lifting borrowing costs for households and businesses.
Higher rates also benefit savers and fixed-income buyers, lifting yields on savings accounts, money-market funds, CDs and new Treasury purchases, though existing bond prices can still fall if yields rise further.

The September 2026 Yield Spike: Unpacking the Causes, Consequences, and Global Financial Risks
Overview
In September 2026, US bond yields surged to near 20-year highs after the Federal Reserve raised interest rates, responding to rising inflation fueled by an energy crisis triggered by the war in Iran. This led to a massive US budget shortfall and increased government bond issuance, while tech giants borrowed heavily at long maturities, all competing for capital and pushing yields higher. The spike in yields quickly drove up mortgage rates and compressed stock valuations, while a stronger US dollar caused severe capital flight from emerging markets. Attempts by the US Treasury to stabilize the market with increased bond buybacks had limited effect, highlighting deep structural pressures.
