The test evaluates gold under opposing macroeconomic outcomes rather than relying on a single inflation forecast. In deflation, weak growth and monetary easing can push real interest rates lower, reducing the opportunity cost of holding a non-yielding asset. In inflation, gold may preserve value as fiat purchasing power declines. A second layer compares the relatively constrained growth of gold production with rapid expansion in government-issued money. Gold’s lack of a corresponding government liability can strengthen its role when confidence in policy or financial stability deteriorates. Passing both scenario tests does not imply a straight-line price rise or justify an unlimited position. It supports treating gold as a volatile portfolio hedge whose size should reflect uncertainty, opportunity cost, and the investor’s risk tolerance.

Core principles
- 01Judge a hedge across multiple macroeconomic regimes.
- 02Treat real interest rates as gold's opportunity-cost signal.
- 03Compare monetary supply growth with gold production growth.
- 04Prefer assets without a government's liability on the other side.
- 05Expect useful hedges to remain volatile rather than rise in a straight line.
How to run it
- 1
Frame both extremes
Write separate deflation and inflation scenarios instead of committing the analysis to one forecast. Identify how each scenario would affect growth, policy, currencies, and portfolio assets.
Pro tip Include a mixed or unstable transition between the two extremes.
Watch out Do not assume that aggressive money creation must immediately produce consumer-price inflation.
- 2
Evaluate real rates
Estimate whether inflation-adjusted interest rates are likely to rise or fall in each scenario. Lower or more negative real rates reduce the income sacrificed by holding gold.
Pro tip Monitor real yields rather than nominal rates alone.
Watch out Gold can still decline while real rates are favorable, especially over short horizons.
- 3
Compare relative supply
Contrast expected growth in gold production with growth in fiat money and central-bank balance sheets. Use the comparison as a scarcity indicator, not as a precise price forecast.
Pro tip Examine trends across major currencies rather than relying on one national money measure.
Watch out Supply comparisons do not capture changes in investor demand, liquidity, or forced selling.
- 4
Assess liability risk
Consider whether holding an asset that is not a government's liability adds diversification during policy or currency instability. Compare that feature with cash, bonds, and bank deposits.
Pro tip Evaluate custody and counterparty arrangements because some gold vehicles introduce new liabilities.
Watch out Gold's independence from government liabilities does not eliminate storage, vehicle, or market risks.
- 5
Size the hedge
Choose an allocation that can contribute during adverse regimes without making the portfolio dependent on one commodity. Define rebalancing rules and acceptable drawdowns.
Pro tip Use scenario contribution and portfolio correlation rather than conviction alone to set size.
Watch out A high-conviction thesis can still cause damaging concentration.
- 6
Monitor invalidation evidence
Reassess the thesis when real rates, monetary growth, financial stability, or supply conditions change. Distinguish temporary volatility from a broken mechanism.
Pro tip Write the invalidation criteria before taking the position.
Watch out Do not reinterpret every adverse price move as proof that the market is wrong.
In the wild
An investor cannot determine whether a severe recession will produce prolonged deflation or whether monetary expansion will eventually create inflation. She tests gold under both regimes, examines real yields and money-supply growth, then adds a modest allocation with predetermined rebalancing and thesis-review rules.
→ The portfolio gains a diversified hedge without depending on a single macroeconomic forecast.
A portfolio manager agrees that constrained gold supply compares favorably with rapid fiat-money growth, but stress testing shows that a large allocation would create unacceptable drawdowns. He caps the position and pairs it with liquid reserves and inflation-linked assets.
→ The hedge remains useful without becoming the portfolio's dominant source of risk.
Common mistakes
Using only the inflation story
Gold's case may also depend on falling real rates during deflation. A one-regime thesis overlooks the framework's main diversification mechanism.
Expecting a straight-line rise
A hedge can experience significant volatility and temporary losses even when its long-term macroeconomic rationale remains intact.
Sizing by conviction alone
Strong confidence in the thesis does not remove commodity risk, timing uncertainty, or the need for portfolio-level limits.
Is it for you?
Best for
Long-horizon investors evaluating a limited gold allocation amid monetary expansion, unstable markets, or uncertain real rates.
Not ideal for
Short-term traders seeking predictable price appreciation or investors unable to tolerate commodity volatility and drawdowns.
From the transcript
“I think that the gold gold is a very good hedge against the instability that the extremes of deflation and inflation.”
“you have to look at gold today is a currency that is no government's liability.”
“at the relative supply fundamentals now and in the future between gold production and the production of FIA money, I think the conclusion is rather…”
