The iShares 20+ Year Treasury Bond ETF (TLT) closed up 1.18% at $88.25 on January 27, 2025, as U.S. Treasury yields fell sharply amid a flight to quality driven by a broad sell-off in equities. The decline in yields was fueled by investor concerns over the economic implications of China's release of the DeepSeek R1 large language model, which led to a significant drop in tech stocks. This market reaction pushed the 10-year Treasury yield down to 4.504%, nearing a critical psychological barrier. Additionally, Morgan Stanley's recent recommendation to buy U.S. Treasuries before the end of a buyers' strike added to the demand for long-term bonds. The absence of immediate tariff increases following President Trump's inauguration further eased inflation fears, supporting lower yields.
