Best Month in a Year for Bonds Sends 10-Year Yield Below 4%

US bonds are wrapping up their best monthly performance in a year against a backdrop of rising global risks, with resurgent demand serving as proof that investors still see Treasuries as the premier haven in turbulent times.

During a month when warning signs flashed alarms in other markets — from real-world evidence of the disruptive and potentially disinflationary power of artificial intelligence to rising geopolitical tensions and worries about hidden dangers in private credit — traders flocked to US government debt.

The result: Yields on 10-year notes — a benchmark for everything from mortgages to credit cards — fell 0.25 percentage points in February, dipping below 4% on Friday for the first time since November. That was part of a stellar month in which a Bloomberg index of Treasuries returned 1.5% and a gauge of long-dated debt gained 4%.

The rally is a reminder that, at least for now, the $30 trillion US government bond market has the edge as a safety play, despite doubts that have sprung up about the defensive appeal of US government securities under the turbulent policies of President Donald Trump’s second term.

“Absolutely US Treasuries will remain a go-to haven trade,” said James Athey, a portfolio manager at Marlborough Investment Management. “The market is far too big, liquid and dominant for it to be completely or easily cast aside as a flight-to-quality destination.”
