10-Year Treasury Yield Hits Highest Level Since 2007

The 10-year Treasury yield climbed to 5.34% last week, marking its highest level since 2007. The yield ended September at 5.29%, representing an increase of approximately 50 basis points since late August.

While rising yields typically increase borrowing costs and pressure stock valuations, UBS analyzed similar yield spikes since 1985 to determine their long-term impact. The analysis found that while the S&P 500 generally remained flat for three months following such events, it typically gained between 5% and 10% over the subsequent six to 12 months.

Market volatility may be heightened by a Shiller CAPE ratio of 41.4, the second-highest level in history. Despite this valuation pressure, historical trends suggest that selling S&P 500 index funds, such as the Vanguard S&P 500 ETF, in response to yields crossing the 5% threshold may be an incorrect long-term investment strategy.
