Why 30-Year Government Bond Yield matters for JPY
The 30-year yield is particularly sensitive to fiscal dynamics and long-run inflation expectations. Sustained selloffs in 30-year bonds can signal markets losing confidence in fiscal sustainability, weighing on the jpy.
How to interpret this series
Rising 30-year yields driven by higher term premium are bearish for the jpy as they signal fiscal risk or loss of inflation credibility. Falling 30-year yields alongside a steepening short end signals a growth scare.
