According to Wall Street strategists, various factors are driving this rise in yields. Ed Yardeni of Yardeni Research pointed out that better-than-expected economic growth in the U.S. has pushed bond yields back to normal levels. However, he also highlighted that rapidly increasing bond yields in France may indicate an impending debt crisis. This situation coincides with ongoing protests across major French cities regarding public education funding, prompting Macquarie strategists to argue that there's a direct connection between the recent civil unrest over proposed budget cuts and the stress in France's bond market.

In addition to France, the U.S. 10-year Treasury yield has seen the most significant increase among over 20 countries tracked by Yardeni Research. Other nations, including Italy, Indonesia, Japan, and South Korea, have also recorded benchmark yield rises of at least 100 basis points since the beginning of the year.

Contributing to the rise in global bond yields are climbing oil prices due to geopolitical tensions in the Middle East and the adjustment of the yen-carry trade. Japanese investors, who had amassed over $1.3 trillion in U.S. Treasurys during the period of negative domestic rates, are now repatriating capital as local yields stabilize. RBC estimates that a $100 billion shift in Japanese holdings can influence 10-year Treasury yields by about 50 basis points. As of July 2026, Japan's holdings have decreased by $120 billion this year and about $300 billion from their peak in 2021.

With the U.S. 10-year Treasury yield approaching its highest level in 24 years, strategists are highlighting a potential risk of reaching 6% for the first time since 2000. Despite the reversion of bond yields to levels seen before the 2008 financial crisis, strong earnings reports and a pause in interest rate hikes from the Federal Reserve are anticipated to support the stock market rally as the year wraps up. Seasonal factors linked to midterm election years are also expected to contribute positively to S&P 500 returns this quarter.
