Indonesia Banking sector, The Transition Tax

TGS has maintained an underweight position on Indonesian banks since 2024. Not because the banks are badly managed. Because we read the policy direction before it appeared in financial statements — and what we read told us that the government was deliberately deploying the Himbara banks as a policy instrument, creating a structural Transition Tax on bank profitability that the valuation screens could not see. The data has confirmed this quarter by quarter: Himbara collective profit growth went from +22.86% in 2023 to -11.26% in Q1 2025. This is Phase 1.
