Symmetrical Mutual Credit Monetary Theory
— Creating New Non-Tax-Based Funding Through Government Financial Structural Reform —
Summary
Abstract
This paper proposes a restructuring of the current fiscal framework, which relies on taxation and government bonds, by redesigning the relationship between the government and the central bank to create a sustainable and stable source of new funding.
The Symmetrical Mutual Credit Monetary Theory establishes a system in which both the government and the central bank function as independent sources of credit, issuing currency based on a symmetrical relationship of mutual trust.
This framework enables fiscal operations that do not depend on taxation and provides a stable foundation for funding new social systems such as Universal Basic Income.
⸻
- Problem Statement
The current fiscal structure faces several fundamental challenges:
• Government spending depends on tax revenue and bond issuance
• Public debt is widely perceived as a burden on future generations
• Fiscal constraints hinder the expansion of social welfare
• Currency issuance power is concentrated in the central bank
As a result, even necessary policies are often constrained by the notion that “there is no funding available.”
⸻
- Core Concepts
2.1 What is Symmetrical Structure
A symmetrical structure refers to the following relationship:
• Government ↔ Central Bank
• Central Bank Currency ↔ Government Currency
Both entities possess equivalent capacity to generate credit.
⸻
2.2 Definition of Mutual Credit
Mutual credit is defined as:
• The liability of one party constitutes the asset of the other
• Both parties mutually support and validate each other’s credit
In this framework, the value of money arises not from a single issuer, but from the relationship itself.
⸻
- Differences from the Current System
Category Current System Proposed System
Currency Issuer Central bank-centered Symmetrical government–central bank structure
Funding Source Taxes + Government bonds Currency issuance based on mutual credit
Source of Trust Tax capacity & bond markets Structural balance of mutual credit
Constraint Fiscal deficit Inflation & supply-demand balance
⸻
- Mechanism of New Funding
4.1 Issuance of Government Currency
The government issues its own currency (physical or digital), characterized by:
• Acceptable for tax payments
• Usable for public expenditure
• Convertible with central bank currency
⸻
4.2 Role of the Central Bank
The central bank is responsible for:
• Conversion between government currency and central bank currency
• Maintaining financial stability
• Adjusting overall credit balance
⸻
4.3 Symmetrical Liability Structure
A key feature of this system is:
• The government holds liabilities toward the central bank
• The central bank also holds liabilities toward the government
This creates a bidirectional liability structure, transforming the concept of debt into:
A balanced and symmetrical credit relationship, rather than a one-sided obligation
⸻
- Application to Universal Basic Income
Within this framework, Universal Basic Income (UBI) can be implemented as follows:
-
The government issues currency
-
Currency is distributed directly to citizens
-
It is used for consumption and tax payments
-
Economic activity sustains and circulates credit
This enables:
• Non-tax-based income distribution
• Sustainable income security
• Automatic economic stabilization
⸻
- Inflation Control Mechanism
In this theory, the primary constraint is not funding, but:
• Productive capacity
• Demand–supply balance
• Money supply
Control tools include:
• Adjustment of currency issuance
• Interest rate policy
• Taxation (as a regulatory tool)
Taxation is redefined not as a funding source, but as:
A tool for macroeconomic regulation
⸻
- Basis of Trust
The credibility of government-issued currency is supported by:
• Its acceptability for tax payments
• Its legal tender status
• Convertibility with central bank currency
• Demand within the real economy
Thus:
Trust is not derived solely from taxation, but from institutional design
⸻
- Key Design Principles
• Redefinition of government–central bank independence
• Transparent accounting of mutual liabilities
• Clear rules for currency issuance
• Institutionalized inflation management
⸻
- Risks and Challenges
• Inflation due to excessive issuance
• Loss of credibility
• Interaction with international monetary systems
• Transitional instability
These challenges are fundamentally:
Issues of scale and management, not structural flaws
⸻
- Conclusion
The Symmetrical Mutual Credit Monetary Theory:
• Redefines the concept of fiscal constraints
• Reconstructs the relationship between government and central bank
• Enables sustainable, non-tax-based fiscal systems
Within this framework:
Social systems such as Universal Basic Income are no longer idealistic concepts, but practical and implementable designs.
