US Bond Yields Hit Two-Decade High: What It Means for Markets

The global debt market has reached a milestone unseen in nearly two decades: US 30-year government bond yields have surged to 5.3%. This allows investors to lock in an annual yield of over 5% in the "safest asset in the world" for decades to come. This trend is not just an enticing offer, but a worrying indicator of a potential storm brewing in the markets.

Reasons for the Yield Surge

This rise is occurring despite weak US economic data: July retail sales were the lowest since May 2025, and the labor market is showing signs of cooling. Beyond domestic factors, the situation is influenced by rising debt-to-GDP ratios in other nations, including Japan, and US inflation, which has remained above the Federal Reserve's target for over five years.

Tamir Hershkovitz and Amir Solomonovitz of Ayalon Insurance note: "The market expects inflation to remain high due to the inability to reach agreements around the Strait of Hormuz, and any drop in oil prices is merely a correction before another wave of increases."

The Role of the Tech Sector

A new variable in the equation is the tech giants, such as Google, Meta, Nvidia, Microsoft, and Amazon. Investments in AI infrastructure require massive capital, and an increasing portion is being financed through the bond market. In the first half of the year, corporate bond issuances exceeded $1.1 trillion, breaking the 2020 record, with interest rates now at 3.75% compared to the previous 0.25%.

Impact on Stock Markets and the Fed

Traditionally, a jump in bond yields creates competition for stocks. However, Wall Street indices remain near peaks, and there is no mass flight of investors into debt. Deutsche Bank warns that current market pricing leaves little room for error; the US economy may remain too resilient, forcing the Fed to tighten monetary policy further.

Fed Chair Kevin Warsh, who took office in May, maintains a hawkish stance. His lack of transparency and refusal to provide clear interest rate guidance add to market uncertainty. Investors are closely watching to see how determined the Fed will be in combating inflation.

Implications for Israel

Israel, which holds approximately $111 billion in US government bonds, will not be immune. The Bank of Israel maintains a significant portion of its reserves in US assets. Ofer Klein, Head of Economics and Research at Harel Insurance and Finance, warns: "When yields rise globally, it is difficult to expect Israel to behave differently over time."

For the general public, this means the cost of money will rise. "When yields rise, the price of money rises," Klein explains. "Mortgages become more expensive, and taking out loans becomes harder." Despite the current strength of the shekel, developments in the bond market could shift this trend.
