    US 10-Year and 30-Year Treasury Yields Breach 5.00% Mark

    Question

    US 10-Year and 30-Year Treasury Yields Breach 5.00% Mark

    Direct answer

    Benchmark U.S. government debt yields have reached milestones above 5.00% on both 10-year and 30-year tenors, surpassing peaks from recent market cycles and returning to 2002 highs. The pressure from elevated long-term rates tests equity valuations and raises debt service costs across corporate balance sheets, even as broader equity benchmarks hold year-to-date advances.
