Policy doesn’t remove pressure.
It moves it.
PolicyLever is a first-order balance-sheet pressure simulator. It shows how policy choices and economic shocks move cash, deposits, reserves and asset values between sectors.
Not a forecast of GDP, inflation or policy outcomes. A transparent double-entry engine that shows who absorbs pressure and where each pound lands.
Access Policy
PolicyLever is free to use.
Two faces of the same pound
The same £1 can be income, pressure, leakage or relief.
It depends where you stand.
System Components
04 / 04Vessels hold stocks
Balance sheets: assets, claims and equity. The static storage of economic potential.
Pipes carry flows
Cash flows: interest, taxes, grants and transfers. The dynamic movement of value.
Valves set rates
Policy choices: rates, fiscal stance and pricing pressure. The control mechanisms.
Gauges show pressure
Non-cash signals: market stress, drag and indicators. The systemic feedback.
How the machine works
Maths. Mechanics. Economics. No AI. No black box.
PolicyLever is deterministic by design. Every number on screen is the direct result of an accounting identity or a labelled parameter — nothing is inferred, nothing is guessed.
Deterministic
Same inputs, same outputs. Forever.
No AI
No trained weights. Nothing to hallucinate.
Conservation
Books must balance or it won't run.
Transparent
Every number traces to an identity.

Why PolicyLever exists
The economy always balances. The question is who carries the pressure.
Balance is not fairness. Equilibrium is not equality. Pressure shows who gains, who pays, and where the money goes.
READ THE MANIFESTO →Distinct Approach
Most economics tools try to predict the future and argue about theory. PolicyLever doesn’t. It shows the mechanics: which way the pipes run, who sits at the receiving end, and which flows repeat every period.
