The 30-year bond yield reached 5.11%, the highest level since May 2025, while the 10-year US note climbed toward 4.6%, a multi-month high. UK gilts saw even sharper selling pressure, with the pound tumbling to its worst week against the dollar since 2024 as British inflation data and political uncertainty around Labour's fiscal plans spooked overseas buyers.

The catalyst for the global bond selloff is a toxic combination of rising oil prices and recession-resistant consumer spending.

The ECB, Bank of England, and Bank of Japan all face similar pressure to hold rates steady or hike despite recessionary risks. Policymakers' credibility on inflation management is now on trial; if they signal another dovish pivot, bond volatility could explode. Conversely, if they tighten further, equities face earnings recession risk. The bond market is pricing in the worst-case scenario: sticky inflation meets growth deceleration.
