The 30-year climbed to roughly 5.4%, while the 2-year jumped to about 4.9%. This is the latest leg of a bond selloff that has been building for months, with the 10-year alone up roughly 35 basis points in September and long-term borrowing costs now pushing into territory we haven’t consistently dealt with since before the Global Financial Crisis.

Inflation fears, pornographic government borrowing needs, spiking oil prices and expectations for additional Fed hikes are all feeding the move. In other words, the bond market keeps trying to tell everybody something, and equity investors keep sticking their fingers in their ears.

Well, the bond market isn’t the equity market. It can’t be gamed, f*cked around with using call options, it can’t be ignored and it can’t be rigged…at least, not without massive consequences. The equity markets in the U.S. are roughly $70 trillion in size, but they ultimately sit on top of the price of money established in the bond market.

Treasuries alone are more than $30 trillion, and their yields help determine what mortgages cost, what corporations pay to borrow, what private equity can finance, what the government pays on its debt and, ultimately, what investors should be willing to pay for a dollar of future corporate earnings. Stocks can ignore that math for a while. They cannot ignore it forever.

It’s as simple as this: as long-term interest rates continue moving higher, virtually every important piece of financial math gets worse, all at the same time.

The discount rate used to value stocks rises, which makes future earnings worth less today. Mortgages get more expensive. Corporate borrowing gets more expensive. Private equity deals and private credit…much of which is already FUBAR but not showing it yet…become harder to finance. Leveraged companies have to refinance debt at higher rates. Consumers pay more to borrow and the federal government pays more to service its enormous pile of debt.

Rising rates are a slow, methodical wood chipper for anything built on cheap money. Anything like…oh, I don’t know…the entire f*cking economy of the last two decades—especially after the Fed went full MythBusters during Covid, rejecting the reality of the economy’s death, and substituting its own by papering over the whole thing with $4 trillion in freshly printed cash…
