Global bond markets experienced a significant selloff, pushing key yields to multi-decade highs. The 30-year Treasury yield reached its highest level since 2004, advancing six basis points to $5.46%, while the 10-year Treasury yield advanced four basis points to $5.16%. This bond rout was attributed to renewed concerns about persistent inflation, increased government spending, and surging corporate borrowing, particularly for the artificial intelligence boom. Money markets are now fully pricing in three Federal Reserve rate hikes over the next year.

Stock markets around the world felt the pressure from rising bond yields and elevated oil prices. While the S&P 500 and Nasdaq staged late rallies to end largely flat, the Dow Jones Industrial Average fell $0.3%. The MSCI World Index also declined $0.2%. Analysts like Byron Anderson of Laffer Tengler Investments noted that higher yields are set to continue, arguing that rate hikes won't resolve issues like oil prices or the AI boom but will increase borrowing costs across the market. Angelo Kourkafas at Edward Jones highlighted that while strong economic growth and corporate fundamentals offer support, the rapid increase in yields and bond market volatility create a significant headwind for equities.

Oil prices remained a key driver of market sentiment, with Brent crude topping $106 after briefly paring gains on reports of potential US-Iran talks regarding the Strait of Hormuz. West Texas Intermediate crude rose $2.5% to $94.47 a barrel. The elevated oil prices fueled inflation concerns and added to the case for interest rates staying higher for longer. The S&P 500 was poised to give back most of its early-week advance as futures dropped $0.6%, and Nasdaq 100 contracts slid $1% on growing concerns that elevated bond yields are eroding the appeal of equities.

The artificial-intelligence-fueled rally that pushed the Nasdaq 100 to a record high earlier in the week began to peter out. Investors are now weighing whether yields are rising due to strong economic growth or increased demand for compensation due to inflation and fiscal risks. Simon Wiersma at ING Bank suggested that while higher yields might not trigger a broad equity bear market, they are likely to cap valuation expansion and make earnings growth increasingly important. The surge in Treasury yields has left investors with few safe havens, with global bonds, stocks, and gold all experiencing declines.
