US Treasury bonds are on track for their best month of the year, with BlackRock's most-traded US Treasury ETF (TLT) up 4.5% since the close of September, surpassing February's 4.24% rally. The 10-year yield fell 14.6 basis points to 5.097% in the week ended October 16, its largest weekly drop since February 13. The rally is attributed to a global equities selloff and declining yields, as investors seek safe haven amid rising oil prices, military conflicts, and inflation.
