US GDP Hits $31.4T, Surging 2.2σ Above Trend Amid Policy Crosscurrents
Q4 2025 GDP reached $31.42 trillion, marking a significant 2.2 standard deviation jump above the 60-quarter moving average of $21.35T. This represents the economy's strongest deviation from trend since the post-pandemic recovery. The surge coincides with unemployment hitting zero percent—an unprecedented labor market tightening that's driving wage pressures and consumer spending. However, the 10-year Treasury yield spiking to 4.47% signals bond markets are pricing in either aggressive Fed tightening or inflation concerns, despite CPI remaining relatively contained at 1.8% quarterly growth. This GDP acceleration against rising borrowing costs suggests either exceptional productivity gains or unsustainable fiscal stimulus. How sustainable is this growth trajectory given monetary policy constraints?
