Macro ThematicRates Govt BondsMacro Economic IndicatorsConsumer StaplesOther

Mizuho analysts dispute claims that a 1% consumption tax rate on food can be implemented without increasing JGB issuance, citing significant funding gaps in their simulations.

Key Takeaways

  • 1.The Japanese government is considering a two-year reduction of consumption tax on food and beverages to 1%, claiming it can be funded without new JGB issuance.
  • 2.Mizuho's analysis suggests the tax cut would create a multi-trillion yen funding gap, overshooting the FY2026 JGB issuance baseline by JPY 10.8tn to 13.1tn over two years.
  • 3.The plan relies on unrealistic tax revenue elasticity assumptions (2.6 to 4.6), which far exceed historical levels (averaging 1.2 to 2.3 since FY2022).
