The Permanent Portfolio from Paraguay: four assets, all the time
The Permanent Portfolio is one of the most elegant allocations ever designed, and probably the most underestimated. Formulated by Harry Browne, an essayist and libertarian candidate for the US presidency, and outlined in his 1999 book Fail-Safe Investing, it is based on a conscious renunciation: rather than trying to guess which economic environment is coming, you build a portfolio that holds up in any of them.
In concrete terms, it consists of four equal parts of 25%: stocks, long-term government bonds, gold, and cash. Each component is designed to shine in a different regime, so that what hurts one benefits another.
For a Paraguayan tax resident, the approach has three converging qualities: it is simple to maintain, it strongly dampens shocks, and its four components, if held abroad, are exempt from local tax due to territoriality. This guide explains how it works, its results, and, more rarely, its limitations. It does not recommend any products and does not constitute investment advice.
The Four Economic Regimes
Browne starts from a simple idea: at any given moment, the economy is in one of four states, or transitioning between two of them.
| Regime | What Happens | What Protects |
|---|---|---|
| Prosperity | Rising growth, employment, profits, and confidence. | Stocks. They are the return engine of the whole. Without them, the portfolio would struggle to beat inflation over the long term. |
| Inflation | Prices rise quickly, the purchasing power of cash erodes, rates rise in response. The 1970s remain the archetype. | Gold. A real asset, it multiplied by more than twenty between 1970 and 1980. Long bonds, conversely, are massacred. |
| Deflation | Prices fall, rates are lowered, demand weakens, the real burden of debt increases. Japan after 1989 provides the longest example, with its benchmark index losing more than 80% in twenty years. | Long bonds. Falling rates mechanically increase their price, all the more strongly the longer the maturity. This is the portfolio's parachute. |
| Monetary Tightening | Central banks raise rates quickly, liquidity becomes scarce, all risky assets correct together. 2022 is a recent illustration. | Cash. It never shines, but it never falls either, and it constitutes the reserve allowing you to buy other assets when they are discounted. |
The genius of the system is that it doesn't bet on anything. Whatever the regime, at least one component works for you. The flip side is symmetrical: in very good years, three out of four components slow down the overall performance. You trade peaks for regularity.
Composition and Supports
| Share | Nature of Support | Points of Attention |
|---|---|---|
| 25% Stocks | A broadly diversified global index fund, ideally covering developed and emerging countries, with annual fees around 0.2%. | Prefer a capitalizing rather than distributing version, and European rather than American domicile, for the tax reasons detailed below. |
| 25% Long Bonds | Benchmark government bonds with maturities over twenty years, via a very low-fee index fund. | The length of maturity is the very function of this pocket. Three-year bonds do not rise enough when rates fall and therefore do not compensate for anything. |
| 25% Gold | Product backed by allocated physical gold stored in a vault, possibly supplemented by directly held gold. This topic is covered in our guide to physical gold from Paraguay. | Avoid synthetic products or those backed by futures contracts, which do not have the same protective function. |
| 25% Cash | Government securities with maturities less than one year, or remunerated cash held with a broker or bank. | This pocket must remain immediately available. That is its sole purpose. |
The total cost of such a portfolio is around 0.10 to 0.15% per year, ten times less than traditional delegated management. Over twenty years and several hundred thousand euros, the difference in fees amounts to tens of thousands of euros.
What the Data Shows
Over the period from 1972 to today, the reference American allocation has approximately the following characteristics.
| Permanent Portfolio | US Stocks | Classic 60/40 | |
|---|---|---|---|
| Annualized Return | 8 to 9% | 10 to 11% | 8 to 9% |
| Annual Volatility | 7 to 8% | 15 to 17% | 10 to 12% |
| Worst Annual Loss | around 13% in 2022 | around 37% in 2008 | around 17% in 2022 |
| Positive Years | more than nine out of ten | around three out of four | around four out of five |
A methodological clarification is necessary, as it is often overlooked: the "worst loss" above is measured on a calendar year basis. The maximum measured drawdown from peak to trough, which is what the investor actually experiences, is significantly deeper, around fifteen to twenty percent in 2022. This is small compared to stocks, but it is not zero.
Behavior in Crisis
This is where the construction is justified. During the oil shock of 1973-1974, gold soared and compensated for the collapse of stocks. In 2000-2002, falling rates caused long bonds to rise while stocks lost almost half their value. In 2008, long government bonds rose by about a third when stocks fell by 37%, and the overall portfolio ended the year roughly even. In March 2020, the decline was contained to less than a tenth where stocks lost a third in five weeks.
The year 2022 deserves special examination, because it is the counterexample. Both stocks and long bonds fell together, gold remained roughly stable, and only cash held up. The portfolio lost approximately 13%, its worst year since its formulation. It resisted better than the alternatives, but the episode demonstrates that diversification by regime is not a guarantee: a rate shock simultaneously affects two of the four pockets.
The Limit Few Articles Mention
It is decisive, and it must be stated frankly.
The historical return of the permanent portfolio was driven by a forty-year bull market in bonds. Long-term US rates started at approximately 15% in the early 1980s to approach zero in 2020. Throughout this period, the bond portion generated both income and significant capital gains.
This configuration cannot be replicated identically from current levels. A bond cannot deliver, at maturity, much more than its initial yield. Protection against deflation remains, since a fall in rates will always increase prices, but the structural contribution to the return of this pocket will likely be lower than what the backtest suggests.
This does not invalidate the strategy, whose primary purpose is stability. However, it does caution against mechanically projecting 8 to 9% per year for the coming decades. Any backtest describes a past, never a future return.
Two Known Variants
The Golden Butterfly is split into five 20% portions: broad market stocks, small-cap value stocks, long bonds, short bonds, and gold. It aims for about an additional percentage point of return, derived from the historical premium of undervalued small-cap stocks, at the cost of slightly higher volatility. Practical reservation: European global small-cap funds mix growth and value, so the desired orientation is never perfectly achieved.
The All Weather, popularized by a major American manager, applies a risk parity logic: 30% stocks, 55% bonds split between long and intermediate maturities, 7.5% gold, and 7.5% commodities. Its volatility is the lowest of the three, its return slightly lower, and its heavy bond weighting makes it the variant most exposed to a rate shock, which 2022 confirmed.
An adaptation to the Paraguayan context
Living in Paraguay justifies two adjustments, provided one accepts the consequences.
A portion of the bond allocation can be placed in local sovereign debt in Guaraníes, whose yield is significantly above benchmark government bonds, as detailed in our guide to the Paraguayan bond market. This is not a substitute: these securities do not have the sensitivity to international rates that provides the protective function of the long-term allocation, and their interest is taxed locally. They pay better, but they protect less.
A fraction of the cash should be held in Guaraníes, equivalent to two or three months of current expenses. This is not diversification, it is natural hedging: rent, groceries, and services are paid in local currency.
Rebalancing
The principle is to periodically bring the allocations back to their targets. If stocks have risen and gold has fallen, you trim the former to strengthen the latter. The operation is counter-intuitive since it involves selling what is going up and buying what is going down, which instinct rejects.
Its primary interest is risk control: without rebalancing, an allocation drifts towards the best-performing pocket and gradually loses its protection. It is frequently stated that it also adds half a point to a full point of annual return. Academic literature is much more divided on this point, and this contribution depends entirely on the period studied. Rebalance to maintain your allocation, not for a hypothetical performance boost.
Three methods coexist. The fixed calendar, quarterly or annually, is the simplest and suits most situations. Tolerance bands, Browne suggested intervening when an allocation moves outside the 15% to 35% range, reduce the number of operations to one or two per year. Finally, rebalancing by cash flows involves directing new savings to the weakest allocation, without ever selling; this is an excellent monthly complement.
A frequency tip: rebalancing too often turns noise into transactions. Four times a year is ample, and the entire management takes only a few hours annually.
Taxation for a Paraguayan Resident
| Treatment | |
|---|---|
| Stocks via a foreign fund | Capital gains and distributions: 0% in Paraguay. There remains the withholding tax levied upstream, the amount of which depends on the fund's domicile. An American fund is subject to 30% withholding on its distributions for a non-resident, with no treaty linking Paraguay to the United States. An Irish fund is subject to 15% at the fund level on US dividends, and nothing at the investor level if it is accumulating. The useful difference is therefore approximately fifteen points on the American portion of dividends, which remains very significant over twenty years. |
| Foreign Government Bonds | 0% in Paraguay, and interest on US government bonds is exempt from withholding tax for non-residents. This is the most efficient pocket of the entire portfolio. |
| Gold | 0%. Gold generates no income, so there is nothing to withhold anywhere. |
| Cash and Short-Term Foreign Securities | 0%, same reasoning as for long bonds. |
| Paraguayan debt in Guaraníes | Local source. Interest taxed at 8%, unless an exemption specific to the issue applies, to be checked on a case-by-case basis. |
In other words, almost all of a permanent portfolio held abroad by a Paraguayan resident is exempt from local tax. Gross return approaches net return, which eliminates the fiscal friction that reduces capitalization in most countries. Over thirty years, this difference outweighs many allocation decisions.
Five Mistakes That Ruin the Strategy
- Abandoning it in a crisis. This is the fatal error. In 2022, two out of four pockets heavily declined, and the temptation was to sell long bonds on the grounds that they "no longer worked." Selling at the bottom turns a temporary loss into a permanent loss. Discipline is the main skill here.
- Shortening bonds. Replacing long maturities with short ones disarms deflationary protection, since it is precisely interest rate sensitivity that does the job. The cash pocket already fulfills the role of short-term stability; the two are complementary, not substitutable.
- Overweighting stocks after a good decade. Recency bias is powerful. Remember that US stocks delivered negative real returns from 1968 to 1982, that the Japanese index lost 80% in twenty years, and that European stocks declined over the twelve years following 2000. Increasing stock allocation means betting that prosperity will last.
- Rebalancing too often. Multiplying operations adds fees, work, and noise, for no benefit.
- Choosing American funds. For a Paraguayan resident, the domicile of the underlying asset matters more than a few hundredths of a percentage point in management fees. This check should be done before purchase, not after.
For Whom
The permanent portfolio is not designed to maximize returns. A 30-year-old investor with 30 years ahead of them would achieve more from a full stock exposure, provided they can withstand 50% drawdowns without selling, which few people are truly capable of.
It suits those who prioritize preservation and regularity: an already built wealth, retirement in progress or near, or simply the refusal to see their capital fluctuate violently. It also suits those who want to spend little time on their investments: four lines and a few hours per year.
Finally, it articulates with the other building blocks of a wealth architecture, described in our guide to the lean family office from Paraguay.
Conclusion
Four assets, four equal parts, periodic rebalancing. The simplicity of the permanent portfolio is its strength, because a strategy that one understands is a strategy that one holds through the storm, and holding on is what distinguishes successful investors from others.
Its past results are remarkable in terms of risk-return ratio, with volatility half that of stocks and incomparable drawdowns. However, they must be read taking into account the interest rate context that produced them, which will not be replicated identically.
For a Paraguayan resident, the additional asset is fiscal: held abroad, these four pockets are not taxed locally, and capital compounds without friction. This is a discreet advantage, but it works every year, silently, in the right direction.
