The 10-year Treasury yield is sitting right at a 25-year resistance line on the monthly chart. If it breaks through, we're in completely uncharted territory for this generation of investors.

This isn't just a technical curiosity. Higher yields mean:

• Mortgage rates stay elevated
• Corporate borrowing costs keep climbing
• Stock valuations face more pressure, especially growth names
• The dollar likely strengthens further

We haven't seen sustained yields above this level since the late 90s. Back then, the economy and market structure looked nothing like today. If this level gives way, it's a regime change—not just another rate move.

Watch this closely. It matters more than most headlines right now.
