The 10-year Treasury yield jumped to 4.39% on March 20, marking a 2.8 standard deviation move above its 60-day average of 4.17% (σ=0.08). This represents the highest level in the recent data series, breaking from a relatively stable trading range. The spike coincides with mixed economic signals: unemployment at a record low 4.30%, CPI rising 1.8% over 3 months to a record high, and GDP growth at 1.4%. This combination suggests bond markets may be pricing in persistent inflationary pressures despite stable employment. The magnitude of this deviation—nearly 3 standard deviations—indicates either a significant shift in market expectations or potential technical factors at play.
