U.S. Treasury yields climbed to levels not seen in decades on Tuesday as the monthslong conflict in the Middle East sparked fresh anxiety over rising inflation. The 30-year Treasury yield hit 5.18%, its highest mark since the 2007 lead-up to the global financial crisis. Global markets mirrored the move, with long-term bond yields in Canada, Germany, France, and the Netherlands all reaching 12-month highs.
High borrowing costs
The spike in yields is creating immediate friction for both households and the federal government. Mortgage rates have remained stubbornly above 6% for a 30-year fixed loan, while the cost for companies to fund AI data center projects has also increased. For the Trump administration, rising yields mean the government must pay more in interest to service ballooning national debt loads.
- The 10-year Treasury yield topped 4.60%, up from less than 4% before the Iran war began in February.
- In Japan, the 10-year government bond yield has climbed back to levels last seen in the 1990s.
- Rising rates have begun to pull down stock markets that were previously trading at records on corporate profit optimism.
The political limit. History suggests these market moves can force policy changes; last year, President Trump backed away from several tariff proposals after steepening rates caused market turmoil. Currently, the administration is facing pressure to manage the economic fallout of the conflict in Iran, which has driven up global oil prices and fueled the current inflation scare.
While a cease-fire is in place between the U.S. and Iran, efforts to secure a lasting peace deal remain stalled. Investors are now watching whether persistent inflation, driven by energy costs, will continue to block any potential for interest rate cuts.
