Long-dated U.S. debt yields surge to 19-year high on inflation fears amid Iran conflict

The 30-year U.S. Treasury yield climbed to about 5.2%, its highest since 2007, as inflation worries and the Iran conflict trigger a global bond rout. The 10-year yield rose around 4.67%, and U.S. stocks fell (Dow −266, S&P −0.8%, Nasdaq −1.15%). A global energy shock, higher commodity prices, and persistent deficits are pushing yields higher, fueling concerns about higher borrowing costs and potential central-bank tightening after April CPI showed the strongest annual increase in three years. The move is mirrored by rising yields in Europe and Japan, highlighting a global surge in funding costs. This is a developing story.
