The Fed just hiked rates again, and one of Wall Street's sharpest minds says the economy is barreling toward a "collision" that will leave working Americans holding the bag — again.

Jeff Gundlach, the veteran fixed-income investor known as the Bond King, warned at a Manhattan event Thursday that surging interest rates risk triggering a recession and a wave of corporate defaults. His message: the institution that inflated the bubble is now pretending to pop it, and Main Street will take the hit while the Treasury stands ready to backstop the bond market.

"It looks like we're on a collision course or something," Gundlach said. "Defaults are going to start coming in fast and furious."

The numbers back him up. The yield on the 10-year U.S. Treasury just broke above 5% for the first time since the summer of 2007 — right before the global financial crisis started to surface, according to Reuters. The Fed raised its benchmark rate a quarter point to 3.75%-4.00%, with all 12 voting FOMC members on board and 16 of 18 participants expecting another hike before year-end. Fed Chair Kevin Warsh cited "persistently elevated" inflation and a strong economy. Reuters framed it as a decisive, hawkish move that "eased some fears" about the Fed's resolve. Gundlach sees the opposite: a trap.

Higher rates mean higher borrowing costs for the federal government and for every American with a mortgage, car loan, or credit card balance. They also mean more stress on corporate debt. Gundlach sketched a scenario where long-dated bond yields push past 6%, forcing the U.S. Treasury to step in with an even bigger intervention. The Treasury already announced $6 billion in long-dated bond buybacks. The market yawned — yields jumped the day it was announced, because the move doesn't touch the fiscal rot underneath.

Business Insider highlighted Gundlach's warning that vulnerabilities in the AI trade and the private credit sector could crack under the strain. AI stock indexes have surged more than 120% since ChatGPT launched in 2022, Reuters noted — twice the pace of global benchmarks. That's a bubble built on cheap money, and cheap money is gone.

Then there's oil. Middle East conflict — Houthi attacks on Saudi infrastructure, the effective closure of the Strait of Hormuz — has Brent crude holding above $100 a barrel. Reuters described it as a "prolonged, unpredictable test of global economic endurance." Gundlach pointed out that countries will soon need to replenish strategic oil reserves drawn down during the Iran war, adding more demand pressure. If consumers start hoarding goods in anticipation of higher prices, you get a self-fulfilling inflation spiral — the very thing the Fed's rate hikes are supposed to prevent.

"The path of least resistance for long-term Treasurys is up," Gundlach said of yields. Translation: borrowing costs keep climbing until something breaks.

The question isn't whether something breaks. It's who gets rescued when it does. The Treasury's buyback program is a down payment on the answer: the bond market gets a lifeline. Working Americans get the bill.
