US 10-year auction just cleared at 4.683% — highest yield since 2007.

That's not a typo. We haven't seen borrowing costs this high at auction in 17 years. Back then, we were staring down the Financial Crisis.

The Treasury moved $42 billion in 10-year paper Wednesday, and the market demanded nearly 4.7% to take it down. That's a meaningful shift in how bond buyers are pricing risk, inflation expectations, and the sheer volume of supply hitting the market.

A few things worth noting:

• Higher yields mean higher debt servicing costs for the government — which feeds back into deficit concerns
• This moves the needle on mortgage rates, corporate borrowing, and equity valuations
• It's a clear signal that bond vigilantes are paying attention again

The parallel to 2007 is uncomfortable, but the setup is different. We're not dealing with subprime contagion — we're dealing with structural deficits, persistent inflation, and a Fed that's still holding rates higher for longer.

For equity investors, this matters. When the risk-free rate pushes toward 5%, growth multiples get squeezed. Rotation into value, dividends, and cash flow becomes more attractive. And if you're holding long-duration tech or speculative growth, you're fighting a tougher discount rate.

Keep an eye on how the curve responds from here. If long-end yields keep climbing while short rates hold, that's a different story than a bear steepener. Either way, the cost of capital just got more expensive — and that has consequences.
