Bond Yields Are Rising. A Bond Nerd Explains Why It Matters

“If you don’t understand the bond market, you don’t understand finance,” says Robin Wigglesworth, an editor at the Financial Times and author of A Fabulous Det: The Epic Story of How Bonds Built the Modern World. Speaking with Morning Brew Daily’s Toby, Wigglesworth makes a case that is both historical and urgent: bonds, not stocks, are the true engine of the global economy. And right now, with yields rising to levels unseen since the financial crisis, the bond market is sending signals that affect everything from government borrowing to your mortgage rate.

What a Bond Actually Is (and Why It’s Not Pokemon Cards)

A bond is a tradable loan—an IOU that can be bought and sold on an exchange. The “yield” is the market interest rate you receive, which fluctuates based on the bond’s price relative to its fixed coupon payment. Wigglesworth explains that while the stock market gets all the attention—because it moves fast and is exciting—the bond market is the bedrock. “The stock market, I always joke, it’s like trading Pokemon cards,” he says. “If you and I buy a stock between each other, it doesn’t really affect Apple or Nvidia. But every day somebody’s selling a bond—your town, your university, your government, the company you work for—that’s where money actually flows.”
