Treasuries at Highest Level in 24 Years: What Changes for Investors

10-Year Treasury Yield Surpasses 5.3% and Reaches 2002 Levels

The yield on 10-year U.S. Treasury bonds reached 5.342% on Thursday, surpassing the peak recorded in 2007 and hitting the highest level since early 2002. This is not an isolated data point: the global benchmark has accumulated its largest quarterly increase this century during the third quarter of 2026.

For those following the markets, the reading is straightforward. When Treasury rates rise at this speed, the opportunity cost of holding money in risk assets increases proportionally. If a bond considered the safest in the world pays more than 5.3% per year, the bar for stocks, cryptocurrencies, and other assets to justify their risk becomes much higher.

Futures for the Dow Jones and S&P 500 already reflected this pressure at the opening on Thursday, trading lower. The Nasdaq, on the other hand, found some support from positive corporate results in the technology sector, specifically from memory chip maker Micron, which reported numbers above expectations.

Why Long-Term Rates Are Rising So Strongly

The rise in long-term Treasuries is due to a combination of factors that have been accumulating over the past few months. The U.S. labor market remains resilient, inflation has not eased at the expected pace, and the Federal Reserve maintains its stance on keeping interest rates high for longer. As we analyzed in our global finance coverage, this scenario has been consolidating quarter by quarter.

The phenomenon is not exclusive to the United States. In the UK, yields on 30-year government bonds touched 6% for the first time since 1998. In continental Europe, stock markets operated with widespread declines, pressured by the same logic: more persistent inflation, higher interest rates for longer, and a less favorable environment for risk assets.

This is a structural movement, not a one-off event. When sovereign bonds from major economies offer nominal returns of this magnitude, the global capital flow reconfigures. Pension funds, insurers, and institutional managers find less reason to seek returns in more volatile assets.

The Role of AI Demand in Supporting the Nasdaq

While the weight of interest rates drags most indices down, the technology sector linked to artificial intelligence remains a partial exception. Micron, one of the largest global memory chip manufacturers, reported quarterly results above market consensus. The company has directly benefited from the growing demand for AI infrastructure, which requires massive volumes of high-performance memory.

This result helped sustain the Nasdaq in slightly positive territory even on a day of widespread pressure. This is not the first time that the AI theme has acted as a shield for the technology sector during times of macroeconomic stress. As we discussed in our technology section, the race for AI infrastructure has created its own investment cycle that, for now, resists the gravity of high-interest rates.

Still, caution is warranted. Even companies with solid fundamentals face multiple compression when the risk-free rate rises. A government bond paying 5.3% with no relevant credit risk is a direct competitor to any stock trading at high multiples.

What to Watch in the Coming Days: Payroll and Nike

This week's economic calendar adds two layers of relevant information. On Thursday, U.S. unemployment claims data will be released. On Friday, the September jobs report, the payroll, will provide a more complete picture of the U.S. labor market.

A strong payroll tends to reinforce the narrative of high interest rates for a longer period, which would push Treasuries even higher. A weaker figure could provide some relief, but it would need to be significantly below expectations to alter the current trajectory. As we have discussed in previous analyses regarding the impact of employment data on the markets, payroll has consistently been one of the triggers for the highest intraday volatility.

On the corporate front, Nike will release its earnings after the market closes. The result will be read as a thermometer of American consumption and the effectiveness of the company's restructuring efforts. In a high-interest environment, companies dependent on discretionary spending face stronger headwinds.

What This Means for Investors in Brazil

For Brazilian investors, the rise in Treasuries has implications on multiple fronts. The first is currency-related: higher interest rates in the U.S. attract capital to American bonds and tend to strengthen the dollar against emerging market currencies, including the real. The second is flow-related: when American fixed income pays more, the relative attractiveness of emerging markets decreases.

The third, less obvious, is about the Selic rate. A global scenario of persistently high interest rates limits the Brazilian Central Bank's room to cut the basic interest rate, even if domestic inflation shows signs of easing. Brazilian monetary policy does not operate in a vacuum, and the interest rate differential between Brazil and the United States is a variable that the Copom closely monitors.

In Asia, markets closed mostly higher on Thursday, led by Japanese stocks. The markets in mainland China and Hong Kong remained closed for a holiday. Oil prices rose, with investors digesting the recovery of Middle Eastern exports amid the impasse in negotiations between the U.S. and Iran.

The global scenario, in summary, is increasingly defined by the gravitation of long-term interest rates. And with Treasuries at levels not seen in nearly a quarter of a century, the cost of ignoring this variable has never been higher.
