Financial Repression, Pt. 1 | Professor Hanno Lustig on Hidden Taxes, Fiscal Sustainability, and Japan’s Debt Puzzle

Financial repression serves as a tool for governments to fund expenditures at below-market rates by shifting the burden from taxpayers to bondholders, a practice historically prevalent during wartime. Hanno Lustig, a Professor of Finance at Stanford University, identifies Japan as a modern case study where the public sector has utilized large-scale asset purchases and yield curve control to maintain low funding costs. By consolidating the central bank, treasury, and public pension funds, Japan effectively executed a massive, levered carry trade, investing in risky foreign assets to offset primary deficits. This strategy acts as a regressive tax on less financially sophisticated households who hold wealth primarily in low-yielding bank deposits. While this approach has temporarily stabilized debt-to-GDP ratios, the recent rise in inflation and interest rates threatens the sustainability of this model, exposing the government to significant interest rate and currency risks.
