10-Year Treasury Yield Spikes to 4.29%, Breaking 60-Day Pattern by 2.2σ
Jan 3, 2026 — Feb 2, 2026 May 17, 2026
The 10-year Treasury yield jumped to 4.29% on Feb 2, marking a 2.2 standard deviation move above its 60-day average of 4.15%. This represents the highest level in the recent dataset, breaking from the narrow 4.12-4.19% range that dominated late 2025 through January. The spike coincides with notable economic signals: unemployment at a record low 4.30%, CPI reaching record highs at 332.41, and GDP growth accelerating 1.4% over 3 months. This combination typically pressures long-term rates higher as markets price in sustained economic strength and potential inflation concerns. The timing and magnitude suggest bond markets may be repricing expectations for monetary policy or economic trajectory.
