    30-year Treasury yield hits 2004 peak as major equity benchmarks slide

    Question

    30-year Treasury yield hits 2004 peak as major equity benchmarks slide

    Direct answer

    The US sovereign yield curve experienced renewed steepening at the long end, with the 30-year Treasury yield breaching highs last recorded in 2004. The move triggered a broad risk-off tone across US benchmarks, compounding headwinds from geopolitical crude strength. Growth and technology equities bore the brunt of the duration adjustment, with the Nasdaq sliding 0.77% and the S&P 500 declining 0.48%, marking two back-to-back down sessions.
