Global Government Bond Yields Approach 4%, Highest in 17 Years, as U.S. and Asian Markets See Broad Sell-Off

Global government bond markets are experiencing a fresh wave of intense selling, with the Bloomberg Global Aggregate Government Bond Index average yield rising to 3.99%, approaching the 4% threshold and hitting its highest level since 2007.

Sticky inflation, surging international oil prices, and substantial government borrowing needs are prompting global financial markets to reassess interest rate paths, fueling expectations that "higher interest rates will persist longer."

U.S. Treasuries, the benchmark for global bond markets, are bearing the brunt. The U.S. 10-year Treasury yield climbed to 5.14%, the highest since 2007. The 30-year long-term bond yield surged to 5.44%, reaching its highest level since 2004, while the 5-year yield broke above the 5% mark.

Even the U.S. Treasury Secretary Scott Bessent’s move in August to expand the Treasury buyback program failed to curb the yield surge. The U.S. 5-year Treasury auction results were extremely weak, recording the highest issuance yield since 2006, highlighting growing market concerns over the interest burden of the nearly $40 trillion federal debt.

Interest rate swap markets have already fully priced in expectations of three Federal Reserve (Fed) rate hikes (25 basis points each) over the next year. Former President Trump expressed dissatisfaction with the Fed’s rate-hiking decisions, urging rates to be lowered to 1% or below, reflecting the political pressure stemming from high mortgage rates and living costs.

Bond market stress is rapidly spreading to global markets. Germany’s 10-year bond yield rose to 3.57%, the highest since 2009. Japan’s 10-year bond yield spiked to 3.15% after a three-day holiday, marking its highest level since 1996. Australia’s 3-year and New Zealand’s 2-year bond yields also jumped simultaneously.

The ICE BofA MOVE Index, which reflects U.S. Treasury market volatility, rose to its highest level since March this year, indicating a significant rise in market panic.

Regarding this bond market selloff, Pendal Group fund manager Amy Xie Patrick stated that against a backdrop of high inflation, tight labor markets, and strong economic performance, “bond market behavior is actually consistent with economic fundamentals.”

Dave Aspell, Co-Chief Investment Officer at Mount Lucas Management, noted that with the Fed hiking again, inflation still off target, and massive government spending, “such extreme volatility in the bond market is quite rare.”

On investment strategy, TD Securities strategist Hans Mikkelsen believes that while fixed-income investors crave high yields, they prefer market stability even more: “Everyone is afraid of catching a falling knife.” Damien Loh, Chief Investment Officer at Ericsenz Capital, advises against blindly buying the dip at this stage and recommends focusing on the risk-reward profile of 2-year/10-year or 5-year/30-year yield curve steepening trades.

Strategists from both JPMorgan and KKR predict that amid energy-driven inflation, government borrowing, and central bank tightening, U.S. Treasury yields still have room to rise further.
