What signal does the U.S. long-term Treasury yield breaking 5% send ahead of the Federal Reserve decision?

```

Amidst the global bond market sell-off, a key financial market indicator is approaching an important psychological threshold.

US stocks came under pressure and fell on Tuesday, with the Nasdaq 100 index dropping 0.8% and all members of the "Magnificent Seven" closing lower. The S&P 500 index fell 0.7%. Meanwhile, the Cboe Volatility Index (VIX) surged from near its lowest levels in recent years, indicating a rise in market risk aversion.

The core of this storm is that the yield on the US 30-year Treasury bond has risen above 5%, the first time since July. This move is not unique; long-term government bond yields in the UK and Japan have also risen similarly. Although the market generally expects the Federal Reserve to cut rates later this month, the rise in long-term rates highlights concerns over inflation and government fiscal conditions, which have surpassed focus on central bank short-term monetary policy.

For investors, a 5% yield is not only an important technical level, but also a psychological warning line. After an astonishing 29% rally in US stocks since early April, rising borrowing costs are forcing the market to re-evaluate lofty stock valuations, especially for rate-sensitive growth stocks, and questions about the sustainability of future economic and earnings growth are emerging.

Global Sell-Off and Fiscal Concerns

The surge in long-term US Treasury yields is a microcosm of the backdrop of global government bonds being sold off. This week, long-term bonds are again facing new pressure, reflecting investors’ concerns over two core issues: the increasingly swollen budget deficit, and the imminent increase in bond issuance this month.

A significant divergence is appearing in the market: On one hand, money markets are betting that the Fed will cut rates by 25 basis points at its September 17 meeting, which will push down rate-sensitive 2-year Treasury yields; on the other hand, investors worry that growing US federal debt will flood the market with long-term Treasuries, prompting them to demand higher returns as compensation.

According to Matt Maley, chief market strategist at Miller Tabak + Co.:

“If inflation is allowed to rebound again, no matter what measures the Fed takes on short-term rates, the market will drive up long-term rates.”

The 5% Psychological Level and Pressure on Stock Valuations

When a key asset's yield hits an integer level like 5%, it often triggers sharp swings in market sentiment. Michael Purves, CEO and founder of Tallbacken Capital Advisors LLC, said:

“For stock investors, when they see the 30-year Treasury yield hit a round number like 5%, market volatility often increases because some investors feel the government is losing control.”

He adds that, further, “there are also algorithmic trading programs that start selling stocks when yields hit specific thresholds.”

Historical experience shows that a breach of 5% on the 30-year Treasury yield has sent different signals to Wall Street in the past. In May this year, when the yield broke above 5%, the S&P 500 quickly dropped 2.3%; but when it soared again in July, it barely stopped the rally in the market.

However, the current environment is different, as the S&P 500 has risen sharply over the past four months, leaving its valuations stretched. The index's forward price-to-earnings ratio has reached 22x, a level surpassed only during the internet bubble and the post-COVID rebound in the past 35 years.

Policy Games and Uncertainty Over Economic Outlook

The current market dynamics are also intertwined with a complex policy environment. Trump has intensified criticism of the Fed, calling for steep interest rate cuts, which could exacerbate any price pressures from his tariff policies. Meanwhile, a federal appeals court ruled that most of Trump’s tariff measures are not permitted. Lifting the tariffs could reduce a government revenue source, but would also ease price pressures.

In any case, rising rates have a direct impact on stock market investors. Higher rates raise concerns about future economic growth and how higher capital costs will affect businesses and consumers. As Maley puts it:

“This raises questions about future earnings growth, which is not good news for an expensive stock market.”

Looking ahead, the market is closely watching the US job openings data to be released later on Wednesday for new clues about the Fed’s room to cut rates. Economists expect July job openings to fall to 7.382 million.

Evelyne Gomez-Liechti, a strategist at Mizuho International Plc, said:

“If the job openings data unexpectedly falls, especially if accompanied by a rise in layoffs and a decrease in resignations, this could be a great combination to prompt investors to buy US Treasuries on dips.”
