Why Long-Dated Bonds Are Falling Out of Favor

Global long-dated bonds are facing renewed selling pressure, significantly driving up borrowing costs worldwide and posing challenges for investors and policymakers. This trend has pushed US 30-year Treasury yields to around 5%, Japan's 20-year notes to their highest since 1999, and UK 30-year gilts to levels last seen in 1998, with similar selloffs observed in French and Australian government bonds.

Analysis

A synchronized and significant selloff is underway in the global long-dated sovereign bond market, leading to a material increase in borrowing costs across major economies. This renewed selling pressure has pushed yields on 30-year US Treasuries back to the 5% level reached in July, while yields on Japan's 20-year notes have climbed to their highest point since 1999 and UK 30-year gilts have reached levels not seen since 1998. The trend is broad-based, with French and Australian government bonds also experiencing a notable selloff. This simultaneous repricing of long-term debt creates a challenging environment for both policymakers, who face higher debt servicing costs, and for investors, who must contend with significant price depreciation in what are traditionally considered safe-haven assets.

Key Decisions for Investors

• Investors should urgently review and potentially reduce duration exposure in fixed-income portfolios, as the ongoing selloff in long-dated bonds is causing significant capital losses.
• Monitor for potential contagion into other asset classes, as a sustained rise in global long-term borrowing costs can negatively impact equity valuations, particularly for growth and technology sectors.
• Given the multi-decade highs in yields for Japanese and UK bonds, investors should be cautious of further upward pressure and consider strategies to hedge against rising interest rate risk.
