Reuters (May 17, 2026, by Suzanne McGee) reports that a spike driving 30-year Treasury bonds above 5% and 10-year yields above 4.5% has raised investor concern that lofty US equity valuations have not priced in inflation risk. The S&P 500 was trading at 21.3x forward earnings vs. the 16x long-term average, indicating elevated bond-equity competition that puts pressure on valuation multiples.
The benchmark S&P 500 traded at 21.3 times earnings estimates for the next 12 months, well above the index's long-term average forward P/E ratio of 16, although it is below the 23.5 level it reached in October. 30-year bonds surpassed 5%; 10-year benchmark yields exceeded 4.5%.
