Global Bond Yields Retreat From Multi-Decade Highs After US Treasury Boosts Buybacks

Global government bond yields pulled back from multi-decade peaks on Thursday, providing markets with a reprieve from a brutal selloff. The rally was triggered by a surprise announcement from the U.S. Department of the Treasury to significantly increase its purchases of government debt, stabilizing fixed-income markets worldwide.

Treasury Intervention Sparks Rally

The U.S. Treasury said on Wednesday it would at least double its buyback operations for 10-year to 30-year nominal bonds to $4 billion per session. The move provides a crucial backstop for less frequently traded "off-the-run" debt, injecting liquidity and quelling investor panic driven by concerns over expanding fiscal deficits.

In response, U.S. benchmark yields fell sharply overnight. The 10-year Treasury yield dropped to 4.647%, while the 30-year Treasury yield tumbled to 5.198%, leading a recovery across global sovereign debt markets.

Asian and European Bonds Follow

The relief rally extended across major international bond hubs, with Asian and European debt posting significant gains.

• Japan: The 10-year Japanese Government Bond (JGB) yield experienced its largest single-day rally since July 14, falling to 2.842%. The move marked a decisive retreat from a 30-year high of 2.945% reached earlier in the week.
• Germany: The benchmark 10-year Bund yield eased to 3.251%, pulling back from a 15-year high.
• France: The 10-year OAT yield also declined, falling to 4.102% after recently touching its highest levels since 2008.

Short-Term Yields and Lingering Risks

While long-dated bonds rallied, shorter-term yields remained under pressure due to expectations of continued restrictive monetary policy from central banks. Germany's rate-sensitive two-year Schatz yield rose for a fifth consecutive session to 2.53%, reflecting market pricing for a potential European Central Bank rate hike next month amid persistent inflation.

Fixed-income strategists caution that the pullback in long-end yields may be a tactical breather rather than a structural reversal. An elevated term premium—the extra compensation investors demand for holding long-term bonds—is being sustained by energy supply threats, with Brent crude holding above $91 a barrel. Investors are now focused on the upcoming Jackson Hole Symposium for guidance from the Federal Reserve Chair on managing inflation and market volatility.
