About Monetary Model
An educational laboratory for the U.S. monetary system
Most people encounter monetary policy as a headline: rates up, rates down, a bank fails, the dollar moves. Monetary Model exists to show the machinery underneath — who holds what claim on whom, which rails money actually travels on, and how a single policy choice ripples through the whole architecture.
The simulator was built by O and P Advisory Services, LLC, the team behind the FLOWOF1 finite-capacity scheduling platform for manufacturers. The same instinct drives both products: complex systems become tractable when you can see the flow and run the what-if yourself.
From Hamilton's 1790 Treasury to today's repo plumbing, every institution, rail and risk hotspot is drawn as a node you can open, trace and compare across time.
Every node is written twice: a Teaching version for undergraduates and an Analytical version that assumes fluency with the mechanisms and the literature.
A stock-flow-consistent open-economy core, rule-based contagion and a Monte Carlo layer — with every assumption and elasticity listed in the app, not hidden in a footnote.
Simulations are thought experiments, not forecasts. We say so on every chart and we correct historical errors when readers find them.
Historical content is researched against canonical sources and reviewed for PhD-level factual accuracy; quotations are presented as debates, with the architect's view set against contemporary criticism. Caricature artwork is original editorial illustration in the tradition of the political cartoon.
Monetary Model is free to explore. A Pro subscription unlocks crisis simulations, uncertainty fans, scenario comparison and exports. Questions? Get in touch.
