Summary
Abstract
------------------------------------------------------------
This paper proposes an alternative fiscal financing architecture termed “Reverse Credit Creation” (RCC). In the conventional model, the government issues sovereign debt as a liability backed by future tax revenues. RCC reverses credit formation: Citizens extend credit to the central bank by purchasing Central Bank Bonds (CBBs), which are liabilities of the central bank and assets of citizens. The central bank holds corresponding assets in the form of long-term loans to the government and income-generating national assets.
We formalize RCC as a three-sector balance-sheet model (Citizens - Central Bank - Government) and distinguish between source of credit, backing of assets, and source of repayment. We derive two sustainability conditions: (1) asset coverage At >= Bt and (2) income condition ra*At >= rb*Bt. Under these conditions, interest payments can be financed without reliance on tax revenue. The model is distinguished from direct monetization and Modern Monetary Theory (MMT) by imposing a strict asset-liability matching rule and an explicit fiscal limit tied to asset profitability and nominal GDP growth.

1. Introduction
------------------------------------------------------------
Standard fiscal circulation:
Government → Issues Government Bonds (Liability) → Finances Expenditure → Repayment via Future Taxes
This creates a direct trade-off: a permanent tax cut creates a funding gap. This paper reframes the problem not as “how far can tax rates be reduced” but as “in which direction should credit be formed.”
In commercial banking, credit flows Bank → Citizens/Firms.
We propose reverse: Citizens → Central Bank → Government.
We call this Reverse Credit Creation (RCC). Unlike MMT, RCC does not assume fiscal space from monetization, but from asset returns.
------------------------------------------------------------
2. Core Balance-Sheet Model
------------------------------------------------------------
Three agents: Citizens (H), Central Bank (CB), Government (G).
Transaction 1: Citizens purchase CBBs
H: Asset + CBB 100
CB: Liability + CBB 100
Transaction 2: CB funds government
CB: Asset + Long-term Loan to Government 100 / Liability + CBB 100
Identity:
H’s asset (CBB) = CB’s liability (CBB) = CB’s asset (Loan to Government)
Citizens do not lend directly to government, preserving central bank independence.
------------------------------------------------------------
3. Separation of Backing and Repayment
------------------------------------------------------------
1. Source of Credit: Democratic credit of citizens to the state.
2. Backing of Assets: Loans to government, financial assets, FX reserves, dividend claims on state-owned enterprises, infrastructure concessions, similar to sovereign wealth funds.
3. Source of Repayment: Interest, dividends, capital gains from (2).
Interest on CBBs is paid from (3) by design, not from taxes.
Principal allows (i) repayment, (ii) rollover into new CBBs, (iii) continued holding as financial asset, (iv) swap with central bank assets.
Goal is not zero debt, but maintaining A >= B.
------------------------------------------------------------
4. Sustainability Conditions
------------------------------------------------------------
Bt: CBB outstanding at t
At: backing assets at t
rb: average yield on CBB
ra: average return on assets
g: nominal GDP growth
Condition 1 - Asset Coverage:
At >= Bt
Central bank must maintain full coverage. Unbacked issuance prohibited.
Condition 2 - Income Condition:
ra * At >= rb * Bt
Asset income must exceed interest payments. As long as this holds, debt service is self-financing without taxes.
If ra < rb, loss emerges requiring tax injection. Primary failure risk.
This is analogous to Domar’s debt sustainability condition but applied to central bank.
------------------------------------------------------------
5. Fiscal Discipline Rule
------------------------------------------------------------
New lending L_new constrained by:
L_new <= (ra*At - rb*Bt) / rL
where rL is expected return on new loans. New lending allowed only within existing interest surplus.
Macro anchor:
Delta Bt / Bt <= g
Growth of CBB must not exceed nominal GDP growth.
These prevent expansion beyond earning capacity and fiscal dominance. Unlike FTPL where price level adjusts, quantity adjusts.
------------------------------------------------------------
6. Differentiation from Existing Debates
------------------------------------------------------------
- Direct monetization prohibited under Japan Public Finance Act Art.5 and EU TFEU 123. In direct underwriting CB asset = gov bond; here assets = loans and income assets.
- Closer to Singapore GIC/Temasek and Norway GPFG.
- Distinct from Berriel & Bhatt (2020) central bank bonds for sterilization; CBBs here are for fiscal funding, not sterilization.
- MMT assumes monetization; RCC assumes asset-backed financing with screening.
------------------------------------------------------------
7. Conclusion
------------------------------------------------------------
Essence is not “how to repay money borrowed from citizens” but “how to transform citizen credit into a financial asset linked to national assets and returns, and maintain it while circulating public finance.”
Sustainability depends on Bt, At, ra, rb, g. Future work: defining assets raising ra and designing GDP-linked CBBs.
