Wall Street's "Most Accurate Man" Warns: If U.S. Debt Yields Break 5%, the End of Days May Begin

Recently, Bank of America’s chief strategist Hartnett issued a new report, sounding an alarm for global markets. He pointed out that the world is currently in a prosperity cycle driven by government money printing, AI spending, and geopolitical games. It appears to be a feast, but hidden dangers lurk—if the 30-year U.S. Treasury yield breaks through 5%, the "door to the end" may open.

U.S. economic data seem impressive, with Q1 GDP growth at 2.0%, but 75% of that is driven by AI investments. Excluding the spending on data centers, computing power, chips, and other AI infrastructure, the true economic performance may be less than 0.5%. More concerning is that from 2020 to 2027, the nominal U.S. GDP will soar from $20 trillion to $35 trillion, a 75% expansion in 7 years. This is not healthy recovery but "nominal prosperity," with the actual purchasing power of money significantly eroded.

The logic behind this prosperity cycle stems from global de-globalization, rising populism, and widening wealth gaps. Governments are spending wildly to break the cycle—fighting trade wars, grabbing key resources like chips, oil, rare earths, and monopolizing supply chains. Since 2020, U.S. government spending has surged by 60%, with the 2027 budget set to increase by another 15%. Global capital is also reshuffling in this "artificial prosperity," leading to increased volatility in investor accounts.

Hartnett emphasizes a historical pattern: before every bubble bursts, long-term bond yields tend to spike first. For example, before Japan’s bubble burst in 1989, Japanese bond yields surged by 230 basis points; before the U.S. internet bubble burst in 1999, U.S. bond yields surged by 260 basis points. Today, the 30-year U.S. Treasury yield at 5% is what he calls the "Maginot Line." The Trump administration is desperately defending this line because major players in Asia and the Middle East hold $3.8 trillion in U.S. debt. Once this line falls, a chain reaction could trigger a market shock.

The current market dilemma also stems from this: markets are hesitant to rise sharply, but when they fall, there are always supports. Everyone is watching this "mine"—the U.S. debt yield.

In short, as long as the 5% threshold for U.S. debt yields holds, this game driven by government money printing, AI spending, and geopolitical struggles can continue; but if it breaks, the script of bubble bursting in history may repeat itself. So, can the "Maginot Line" at 5% hold this year? How long can the AI boom last? These are questions investors should keep paying attention to and pondering. #WCTC交易王PK $BTC ‌$ETH $SOL ‌
