  • The yen’s depreciation has fueled imported inflation, while GDP contraction and weak household sentiment highlight deep structural vulnerabilities.
  • Potential ripple effects include global bond market pessimism, reduced Japanese flows into US assets, and upward pressure on US Treasury yields.
