Money Supply
Money supply is the measured stock of money — M0/MB, M1, M2 — a quantity that depends on what you count as money.
Definition
Money Supply refers to m0/MB, M1, M2 — a quantity that depends on what you count as money. Keep that definition fixed when comparing series, managers, or regimes — renaming the same tape does not create a new signal.
Why it matters
It is a named object desks use to frame risk, positioning, or process. When m0/MB, M1, M2 — a quantity that depends on what you count as money shifts, related hedges, limits, and narratives usually need an explicit update rather than a quiet assumption.
Case
Suppose a desk is positioned for the opposite of what money supply is saying. If m0/MB, M1, M2 — a quantity that depends on what you count as money moves against that book, the first question is not “is the story clever?” but whether size, hedges, and stop logic still match the observation.
How to read it
Keep the definition fixed, then challenge it with cross-checks before sizing. Prefer a short written null hypothesis for Money Supply: what would falsify the current reading in the next window?
