Long-term bonds are the focus of investor anxiety, with concerns from inf to a debt-fueled AI boom driving a global rise in sovereign yields.

Long-term bonds are the focus of investor anxiety, with concerns from inf to a debt-fueled AI boom driving a global rise in sovereign yields. This week the 30-year US Treasury yield reached its highest since 2007, French borrowing costs hit levels not seen since 2008, German yields are near 2011 highs, UK yields are approaching 6%, and like-maturity Japanese yields are near record highs. While domestic factors differ, the move reflects global structural forces: a more fragmented world raising the risk of supply shocks and persistent inf; worries governments may be unable to rein in spending, sustaining higher rates; and market-structure and demographic shifts that have eroded formerly stable buyer demand. AXA IM Core CIO Chris Iggo said: "It's hard to judge what yield level would improve total return prospects for long-dated fixed income. Only a sudden weakening in economic data or some external shock would change that picture; the latter appears more likely."
