The Monetary Inflation Ratio compares growth in total purchasing power—money plus credit—with growth in the quantity of goods and services available. When spending power expands faster than real output, the excess bids up goods, services, or financial assets, reducing the value of money. Dalio distinguishes this from a “beautiful deleveraging,” where newly created money fills a contraction in credit and prevents total spending from collapsing. The analysis therefore requires both sides of the equation: how much money and credit were added, and how much production or lost credit they offset. It also directs attention from nominal balances to real purchasing power. The ratio is a diagnostic rather than a complete forecast, but it offers a clear mechanism for evaluating whether policy is neutralizing contraction or creating excess demand.
Origin
Dalio presented the mechanism in his explanation of how the economic machine works and used it to contrast post-2008 money creation with the much larger fiscal and monetary response during the pandemic.
Core principles
- 01Prices reflect spending power relative to available quantity.
- 02Money and credit both contribute to total purchasing power.
- 03Creating money to replace collapsing credit differs from creating excess spending power.
- 04Inflation can appear in goods, services, or financial assets.
- 05Nominal stability can conceal a loss of real purchasing power.
How to run it
- 1
Measure spending-power growth
Estimate the incremental amount of money and credit available for spending during the period. Include fiscal transfers financed through central-bank-supported issuance when relevant.
Pro tip Examine both money and credit because either can fund purchases.
Watch out Looking only at the monetary base can miss large changes in private or public credit.
- 2
Measure real supply growth
Estimate how much the quantity of goods and services increased. Adjust for contractions, capacity limits, and sectors where supply cannot respond quickly.
Pro tip Use real output rather than nominal GDP when possible.
Watch out Aggregate output can hide severe bottlenecks in individual sectors.
- 3
Compare the rates
Determine whether money-and-credit growth merely replaces lost spending or materially exceeds output growth. A larger excess indicates stronger monetary inflation pressure.
Pro tip Compare changes over consistent time periods.
Watch out The ratio is directional and should not be mistaken for an exact CPI prediction.
- 4
Trace where spending flows
Identify whether recipients are likely to buy consumer goods, services, property, or financial assets. Inflation may first appear wherever the additional purchasing power is directed.
Pro tip Track asset inflation as well as consumer-price measures.
Watch out A stable headline CPI does not prove that money creation had no inflationary effect.
- 5
Evaluate real outcomes
Convert cash yields, bond yields, and portfolio returns into inflation-adjusted terms. Judge safety by preserved buying power rather than low nominal volatility.
Pro tip Compare returns with the inflation measure most relevant to the investor's future spending.
Watch out A stable dollar balance can still represent a substantial real loss.
In the wild
During the financial crisis, collapsing credit reduced spending power. Dalio argues that creating money to replace that shortfall could neutralize the contraction without generating the same inflation pressure as creating spending power far beyond the missing credit.
→ The example distinguishes stabilizing money creation from excess creation using the same money-credit-output mechanism.
Common mistakes
Blaming only supply chains
Supply constraints can affect prices, but ignoring the quantity of money and credit misses the demand side of the mechanism.
Looking only at nominal wealth
A cash balance can remain unchanged while its purchasing power falls. Real returns are the relevant measure of preserved wealth.
Treating all money creation alike
Money that fills a credit contraction has a different spending effect from money that pushes total purchasing power far above available output.
Is it for you?
Best for
It is best for investors and policymakers evaluating inflation pressure, purchasing-power risk, and monetary responses to contractions.
Not ideal for
It is not ideal as a precise short-term inflation forecast when supply composition, velocity, and timing differ sharply across sectors.

“the price of anything equals the amount spent on it, and it could be money or credit divided by the quantity of its sold.”
“if I increase money or credit by more than I increase the goods and services produced, you will have inflation in good services or financial…”
“Take the amount the increase in the amount of money and credit and divide it by the amount of goods and services increased, and you're…”
