Treasury Yields Hit One-Month Lows as European Fiscal Crisis and AI Sell-Off Drive Safe-Haven Demand

Key points

• The 10-year U.S. Treasury yield fell 15 basis points to 4.996%, marking the first time it traded below 5% since September 23, 2026.
• The 30-year Treasury yield dropped to 5.32%, a one-month low, as long-term investors rotated out of European paper into U.S. assets.
• French 10-year government bond yields surged past 5% to 24-year highs, with the spread between French and German bonds widening to 157 basis points.
• The 2-year Treasury yield fell to 4.69%, reflecting market expectations that the Federal Reserve will hold its policy rate at 3.75%-4.00% at its October 28 meeting.
• Equities suffered a broad sell-off, with the Nasdaq falling over 2% and Nvidia shares dropping nearly 4% after CEO Jensen Huang cited capital scarcity despite high demand.

Background

This move follows a period of rising yields in late September 2026, when the 10-year Treasury yield peaked at 5.208% due to inflation fears and rate hike expectations. Earlier in September, analysts noted that despite high yields, stock markets remained resilient due to AI infrastructure spending. The current decline represents a sharp reversal from those highs, driven by external geopolitical and fiscal shocks rather than domestic economic cooling.

How outlets are covering it

Investing.com attributes the Treasury rally primarily to a 'flight to quality' from European sovereign debt, specifically highlighting France's fiscal crisis and the widening spread with German Bunds. CNBC, however, emphasizes the role of the equity market sell-off, citing concerns over AI capital scarcity and surging oil prices as key drivers. While both outlets agree on the safe-haven nature of the move, Investing.com focuses on the European debt crisis as the catalyst, whereas CNBC highlights the tech sector's volatility and geopolitical tensions in the Middle East. Both note the 10-year yield breaking below 5%, but Investing.com provides more detail on the specific European yield spreads, while CNBC focuses on the broader market reaction and oil prices.

Why it matters

The drop in Treasury yields signals a significant shift in global risk appetite, with investors prioritizing safety over yield in the face of European fiscal instability and tech sector volatility. The 10-year yield breaking below 5% could lower borrowing costs for mortgages and corporate debt in the U.S., potentially offsetting some inflationary pressures. However, the simultaneous spike in oil prices and the sell-off in AI stocks suggest underlying economic fragility. The divergence between U.S. and European yields also highlights the relative strength of the U.S. dollar and Treasuries as global safe havens, which could impact currency markets and international capital flows in the coming weeks.

What to watch

Investors are now focused on the Federal Reserve's October 28 meeting, where a rate hold is expected, and the European Central Bank's decision later in the week. The market is also watching for any escalation in Middle East tensions, which could further drive oil prices and risk-off sentiment. Additionally, the performance of AI stocks and the resolution of France's fiscal crisis will be critical in determining whether the safe-haven bid for Treasuries continues or reverses in the coming days.
