The 10-year Treasury yield just hit 5.15% — highest since June 2007.

That's a +70 basis point move in one month. The bond market is pricing in pain like the Fed's hiking 50 bps at a clip.

This isn't noise. When yields spike this fast, it ripples through everything: mortgage rates, corporate borrowing costs, equity valuations.

Historically, moves like this don't happen in a vacuum. Either inflation expectations are re-accelerating, growth fears are subsiding (so less demand for safety), or both.

Q4 is setting up to be volatile. Watch how stocks react if yields hold above 5%. Tech and growth names especially feel the heat when the risk-free rate climbs this aggressively.

Stay sharp.
