To protect monetary policy from fiscal dominance and prevent hyperinflationary cycles, modern legal frameworks implement strict structural boundaries.
Enforcing Central Bank Autonomy
Central banking statutes globally establish hard legal restrictions on state financing:
  Policy Action  |   Regulatory Statutory Constraint    |   Macroeconomic Stability Outcome
-----------------+--------------------------------------+-----------------------------------------
  Primary Market | Strict legal prohibition of purchases| Prevents direct currency printing traps
  Secondary Market| Permitted via open market actions   | Controls short interest rate corridors

By legally prohibiting the central bank from purchasing government bonds directly from the state treasury on the primary market, these frameworks insulate monetary implementation from direct state funding demands, supporting institutional credibility.
