US Treasuries Head for Best Week Since February as AI Valuation Fears Drive Safety Rally

The Quick Take

• US Treasuries were on track for their best week since February, with borrowing costs pulling back from decade-plus highs.
• AI sector jitters — concern about stretched valuations and data centre debt loads — triggered a risk-off rotation into government bonds.
• The yield retreat represents a meaningful reversal of the bond rout that had pushed 10-year Treasury yields to levels not seen since 2007.

US Treasuries' best weekly performance since February marks a significant shift in market positioning following months of sustained yield pressure that pushed 10-year rates to multi-decade highs. The Financial Times attributes the safety rally partly to AI sector jitters — specifically investor concern that the enormous debt loads accumulated by AI infrastructure companies like CoreWeave represent a systemic risk if technology sector growth underwhelms. When growth-oriented risk assets suffer credibility problems, capital historically rotates into sovereign debt as a flight-to-safety trade.

The yield retreat creates a favourable environment for rate-sensitive equity sectors including real estate investment trusts, utilities, and high-dividend consumer staples, which had underperformed sharply during the bond rout. Mortgage-backed security spreads typically narrow when Treasury yields fall, providing relief for US housing affordability. Investment-grade corporate bond issuers seize on falling yields to refinance at lower costs, improving balance sheet metrics for capital-intensive industries.

Key forward signals include next week's US jobs report and CPI data, which will determine whether the Federal Reserve can sustain any pause in its tightening bias. A weak employment print would extend the Treasury rally, while a hot CPI would likely reverse it by restoring rate hike expectations. The macro variable is AI sector earnings guidance — if large-cap technology companies deliver strong AI monetisation evidence in upcoming earnings, the flight-to-safety thesis fades rapidly as risk appetite recovers, pushing yields back toward recent highs.
