Rising Yields Spark Boom-or-Bust Debate as Treasury Yield Hits 5-Year High

The 10-year Treasury yield has reached its highest level since 2007 at 5.21%, causing Wall Street to wonder if this is a sign of a booming economy or a potential bust.

When the Federal Reserve raised interest rates last week, markets expected another hike in October with roughly 70% odds. This increase has led to higher borrowing costs for car loans, credit cards, and business loans, following the average 30-year mortgage rate jumping to 7.45%.

Economists are divided on whether rising yields are due to a booming economy or investors losing their taste for US debt. The yield moves with demand; when fewer investors want to lend, the government has to offer a higher rate to find buyers.

The case for boom suggests that yields are rising because the economy is strong and there's real growth, much of it from AI. The largest hyperscalers are on track to devote nearly $800 billion to capital expenditures this year and more than $1.1 trillion in 2027, according to Goldman Sachs.

On the other hand, pessimists worry about the term premium starting to climb amid risks that the Fed can't control, such as a war with Iran and an increasing deficit.
