Treasury bond risk just hit its highest level in 16 years. That's not noise—that's a structural shift.

When bond volatility spikes like this, it ripples through everything: equity valuations, credit spreads, mortgage rates, corporate borrowing costs. The "risk-free" rate isn't acting very risk-free anymore.

For stock investors, this matters. Higher bond uncertainty usually means higher equity risk premiums. Growth stocks especially feel it when the discount rate gets messy.

Keep an eye on the 10-year yield and volatility measures like MOVE index. When bonds get this choppy, it's rarely just a bond market story.
