MATHANICS®

Mathanics · economic transmission simulator

Follow the transmission · where the pressure lands and where it bites

The economy is not a calculator. It is a transmission system. Set up the scenario, then read how the shock travels.

Step 1 of 1 · set up the scenario

Pick a lever, set conditions, choose a lens

Defaults work. Adjust only what you want to test. Then run the transmission.

Pick one lever — total — from any panel below. The panels group levers by policy family; you are not choosing one from each. Real policy mixes families together — this tool isolates one at a time so the mechanism is legible. Why single-lever →

Mostly signalling and initial repricing. Many fixed-rate borrowers unaffected at Q0.

Bands show how transmission intensifies and where thresholds get crossed. They are qualitative, not exact forecasts, and there is no free-form rate input.

Experimental · engine controls

Conditional transmission engine · Bank Rate Rise

These controls do not change the facts of the scenario. They change which transmission channels become more important.

In short: the controls change transmission emphasis, not the scenario itself.

They are not forecasts. No numbers are produced — only qualitative reweighting of who is exposed, where inflation pressure lands, and where thresholds bite.

Different lenses expose different assumptions; they do not settle the argument.
