Soaring Global Bond Yields Spark Stock Market Downturn Warnings

Global bond yields, the interest paid for borrowing money worldwide, are rising sharply, fueling growing concerns that stock markets could decline. U.S. 30-year Treasury yields hit their highest levels since 2023, and the average 10-year Treasury yield for major Group of Seven (G7) developed nations reached its highest point since 2004. A confluence of rising oil prices stemming from Iran, the phenomenon of "chipflation," and increasing government debt in various countries has sent G7 government bond yields soaring to multi-year highs.

The International Monetary Fund (IMF) projects global public debt to reach 100% of Gross Domestic Product (GDP) by 2029. The U.S. Congressional Budget Office (CBO) forecasts U.S. debt to hit 120% of GDP within the next decade.

Traders are pricing in rate hikes through March 2027, with the Chicago Mercantile Exchange (CME) FedWatch Tool showing an approximate 50% probability of a 25 basis point (bp) rate increase by December. The market is pricing in an 85% chance of a 25 bp rate hike at the next European Central Bank (ECB) meeting. Analyses suggest the bond market is more concerned that the Fed chair might tolerate inflation over further rate hikes.

Volatility has appeared in interest-rate sensitive market segments, with the small-cap Russell 2000 index recording its largest daily drop since November. Year-end target prices for the S&P 500 index remained unchanged at 8250-8300.

U.S. Treasury Secretary Scott Bessant attended the G7 Finance Ministers and Central Bank Governors meeting in Paris on May 18 (local time). The U.S. Treasury Department has renewed a 30-day waiver on sanctions limiting transactions involving Russian crude oil. This exemption is effective until June 17 and applies only to Russian crude oil and petroleum products already loaded onto tankers and at sea. Newly produced or recently shipped Russian oil is not included. The U.S. Treasury has imposed a $275 million fine on India's Adani Enterprises, suspected of illicitly importing Iranian liquefied petroleum gas (LPG) disguised as Omani and Iraqi origin.
