Government bond yields across major economies climbed sharply, extending a global sell-off that pushed Germany's 10-year Bund yield to its highest level since March 2011 and drove the U.S. 30-year Treasury yield to its highest level since 2007. The move broadened beyond the eurozone, with Japan's 10-year government bond yield nearing 3%, UK 10-year gilt yields moving into 5.0% territory, and France's 10-year yield hitting a 16-year peak. The repricing gathered pace as hopes for a U.S.-Iran peace deal faded, lifting Brent crude to around $91 a barrel and reviving inflation concerns. Germany's bond decline was reinforced by stronger-than-expected August ZEW economic sentiment data, which reduced demand for safe-haven debt and supported expectations that the European Central Bank may need to keep policy tighter for longer. Analysts also pointed to broader pressures including high government debt, supply concerns, and investors demanding more compensation for holding long-dated sovereign bonds. In the United States, the 10-year Treasury yield traded around 4.74% while the 30-year reached 5.324%, and recent 10-year and 30-year Treasury auctions cleared at the highest yields in 19 years and 25 years respectively. The rise in yields has started to affect global capital flows, with Japanese investors finding domestic bonds more attractive as local long-dated yields rise, while U.S. data showed foreign Treasury holdings fell in June. The sell-off also weighed on equities in Asia and pointed to tighter financial conditions globally, as higher sovereign yields raise borrowing costs across the wider economy.
