Policy doesn’t remove pressure.
It moves it.

Pull a lever and see how pressure shifts between households, businesses, government and markets — with the assumptions visible at every step.

Run the Pressure Machine Read the methodology

A high-level pressure-transfer model for understanding policy trade-offs.

COORD: 51.5074 N

PRESSURE: OPTIMAL

Access Policy

PolicyLever is free to use.

It follows a teaching £1 through the economy so people can better understand pressure, relief, leakage and trade-offs.No paywall. No financial advice. No forecasts.Just a clearer way to see where economic pressure lands.

A pound sign split in two halves — one side glowing with upward flows, the other a corroded machine of pipes and pressure gauges

Two faces of the same pound

The same £1 can be income, pressure, leakage or relief.

It depends where you stand.

Pressureon the payer

Leakageout of the system

System Components

04 / 04

Vessels 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.

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.

Every output is a booked ledger flow or a labelled pressure gauge. Nothing is hidden. Nothing is a forecast.
