Long-term government bond yields across G7 nations have reached levels not seen in decades, with the 30-year US Treasury yield hitting 5.33% on August 18, 2026, its highest since 2007. US national debt crossed $40 trillion in 2026, with annual interest payments surpassing $1 trillion for the first time. The UK faces gilt yields approaching 6%, a level not seen since 1998, and net debt interest estimated at £109 billion for 2026/27. France projects debt-servicing costs of around €59 billion in 2026, while Italy may consume roughly 9% of government revenue on interest by 2028. Since 2024, interest payments have exceeded defense spending in most G7 nations, and developed-market general government debt is forecast to reach $75.8 trillion, approximately 104% of GDP, by the end of 2026.
