Monetary ratios

What no agency publishes as a single number: the money multiplier, how much of the base is reserves, and how reserves compare with the deposits they settle. Each is two Federal Reserve series divided on the same dates.

Money multiplier (M2 divided by the monetary base)

How many dollars of broad money exist for each dollar of central bank money. The textbook treats this as a stable multiple set by the reserve requirement. Measured, it is an outcome of how banks and the public behave, and reserve requirements have been zero since March 2020.

Reserves as a share of the monetary base

The monetary base is currency in circulation plus reserve balances. When reserves were scarce the base was almost all currency, so the rise in this share marks the move to ample reserves. Before 2020, total reserves also counted vault cash applied to reserve requirements, which the base counts as currency, so readings from that era overlap slightly.

Reserve balances as a share of bank deposits

Reserves scaled by the deposits they settle. It is one practical gauge of how ample reserves are. No agency publishes a threshold at which ample becomes scarce.

Method

Every input is a Federal Reserve series retrieved from FRED and normalised to billions of dollars on ingest (see methodology). A ratio is only computed on a date for which both of its series have an observation. Weekly series are matched to weekly series and monthly to monthly; nothing is interpolated or carried forward. The inputs are revised by the publishing agencies, so historical ratios change when the source does. The CSV carries every matched observation with both inputs, so each figure here can be checked.

Monetary ratios: common questions

What is the money multiplier today?
M2 divided by the monetary base was 4.31x on 1 August 2026: about 4.31 dollars of M2 for each dollar of base money. Computed by M0 from FRED series M2SL and BOGMBASE on the same monthly date.
What is the highest and lowest money multiplier on record?
Across 812 months from 1 January 1959 to 1 August 2026, the highest reading was 11.76x in Feb 1985 and the lowest was 2.82x in Aug 2014.
How much of the monetary base is bank reserves?
Total reserves were 54.3% of the monetary base on 1 August 2026, against 5.3% in Aug 2006. The rest of the base is currency in circulation.
How are these ratios calculated?
Each ratio divides one Federal Reserve series by another on identical observation dates, with no interpolation, so a date on which either series has no print is left out. M2 velocity is published by FRED as a ratio and is shown as published.
