Bond yields have climbed sharply, creating headwinds for stock investors as borrowing costs rise across the economy. The 10-year Treasury yield and other benchmarks have moved higher, reflecting expectations for sustained inflation and potentially higher interest rates ahead.

This yield surge matters directly to your portfolio. When Treasury yields rise, bonds become more attractive relative to stocks.
