The model
The simplified model has four equal sleeves.
Harry Browne and Terry Coxon introduced the Permanent Portfolio concept in their 1981 book Inflation-Proofing Your Investments. Earlier versions had more than four asset groups; the model was later simplified to equal shares of stocks, bonds, cash, and gold. [1][2]
In the simplified model, each group has a 25% target. The mix is framed around four possible economic conditions—prosperity, deflation, recession, and inflation—so it does not rely on predicting which one comes next. These weights describe the model; they are not a suggested allocation for you. [5]

25% of the model
Stocks
For prosperity. Broad ownership of companies is meant to participate when businesses and the wider economy grow. Stock values can still fall sharply. [6]
-
25% of the model
Long-term government bonds
For deflation. When interest rates fall, existing long-term government bonds can rise in value; they can also lose value when rates rise. The classic U.S. model uses long-term U.S. Treasury bonds for this sleeve. [7]
-
25% of the model
Cash and short-term government bills
The liquid reserve. In the classic U.S. model, Treasury bills serve as the liquid reserve and a source of funds for rebalancing. [8]
-
25% of the model
Gold
For inflation and currency uncertainty. The model uses exposure to gold itself as a potential store of value when money loses purchasing power. Gold can also be volatile and lose value. [1][14]
These four sleeves describe the simplified Permanent Portfolio model, not a customized InterBuckets portfolio. The classic implementation is U.S.-centered; the strategy can be adapted for international investors using broad local stock exposure and bonds and cash in their own government debt and currency. The examples below are possible ways to represent each sleeve, not recommendations. Their fee ordering is explained with the table. [9]
Implementation examples
Exchange-traded examples for each sleeve.
Stocks, bonds, and cash examples are U.S.-listed ETFs. Gold examples also include Canadian-listed ETFs and European-listed, gold-backed ETCs. Listings and trading currencies are shown beside each option. This is a starting point for research, not a recommendation or a complete list of available products.
Trading currencies are shown for each listing; a listing currency does not by itself describe or hedge all currency exposure. European gold ETCs are certificates backed by physical metal, not ETFs. Fee labels, units, and reporting dates vary across issuers and are not directly comparable. Within each sleeve, examples are ordered from lowest to highest by the issuer-stated annual fee figure shown; this ordering is not an overall cost, performance, or suitability ranking. Issuer pages checked October 27, 2026. Brokerage, trading, tax, and currency-conversion costs are not included.

The diversification idea
Hold different kinds of assets together.
The model groups broad asset categories instead of relying on a forecast about which market will lead. Rowland and Lawson describe its design as passive and intended to avoid market timing. That describes the model’s design, not its results over any period. [1]
Diversification means spreading investments among different assets to reduce risk. It cannot guarantee against losses when markets fall, and different asset categories can decline at the same time. [4]
A portfolio term
What rebalancing means.
When asset values change at different rates, each part can drift away from its chosen target. Rebalancing means bringing the mix back toward those targets, sometimes by changing holdings or directing new contributions. [3]
Common approaches include:
- Calendar-based: review or rebalance at set intervals, such as every six or twelve months. [3]
- Threshold-based: rebalance when an asset group moves outside a preset range around its target. [3]
- Combined: review on a schedule and trade only if a preset range has been crossed. [10]
New contributions can also be directed toward underweight parts of a portfolio before selling anything. Each method can lead to different trades. Fees, account rules, and tax treatment may affect which approach fits an investor’s circumstances. [3]
Long-term planning
The habits behind a long-term plan.
These five points are a brief selection from Harry Browne’s financial-safety rules, included in Craig Rowland and J. M. Lawson’s book about the Permanent Portfolio. They are not a separate five-step formula. The allocation describes what a portfolio holds; these principles address the decisions around it. [13]
- 01
Build on your earning power.
Your work and skills help create the income you can save and invest.
- 02
Understand your choices.
Know what each investment does and why it belongs in your plan.
- 03
Keep the plan understandable.
A plan you can explain is easier to review and maintain.
- 04
Resist market timing.
Changing your allocation in response to each forecast adds decisions that can pull you away from your plan.
- 05
Keep speculation separate.
Decide which money is for long-term goals and which, if any, you are willing to risk on speculative ideas.
