Permanent Portfolio and Property Investing in Singapore (2026)

How the Permanent Portfolio of stocks, bonds, gold and cash compares with Singapore property investing, with leverage maths, stamp duties and price history.

The Permanent Portfolio is a deliberately dull mix of four assets: stocks, long-term bonds, gold and cash. It aims to hold up in any economic climate rather than to win in one. Property is not one of the four. That is not an oversight you can fix by adding a fifth bucket, because a home is lumpy, leveraged and expensive to trade. If you already own a home, you also already hold a very large property position, so the useful question is how the two fit together.

At a glance

  • The classic version puts 25% in each of stocks, long-term bonds, gold and cash and rebalances about once a year (Fail-Safe Investing, Harry Browne).
  • It targets smaller swings, not the highest return. Gold pays no income, and the cash and bond slices drag in a long boom.
  • Property breaks the model in three ways: you cannot sell part of a house to rebalance, the loan multiplies gains and losses, and Singapore stamp duties make trading costly.
  • On a S$1m first home with 25% down, a 10% price move changes your cash stake by about 36%.
  • Singapore’s private home price index fell 11.6% from Q3 2013 to Q2 2017 and took until Q4 2020 to regain its peak.

What the Permanent Portfolio is

Harry Browne, an American investment writer, set out the idea in his book Fail-Safe Investing. He argued that the economy moves through four conditions, and no one can reliably predict which comes next:

  • Prosperity. Stocks do well.
  • Inflation. Gold does well.
  • Deflation. Long-term bonds do well.
  • Tight money or recession. Cash does well.

So you hold all four in equal parts and let something always be working. Browne’s version used US assets. A Singapore investor would pick local equivalents for each slice, and that choice (which funds, which bonds, how to hold gold) matters more than the headline split. This article does not recommend products.

How rebalancing works: a worked example

This is an illustration with made-up returns and no trading costs. Say you start with S$400,000, or S$100,000 in each slice. After a year, stocks are up 30%, bonds are down 10%, and gold and cash are flat.

SliceStartAfter one yearWeight
StocksS$100,000S$130,00031.0%
Long-term bondsS$100,000S$90,00021.4%
GoldS$100,000S$100,00023.8%
CashS$100,000S$100,00023.8%
TotalS$400,000S$420,000

Each slice should now be S$105,000. You sell S$25,000 of stocks. You buy S$15,000 of bonds and S$5,000 each of gold and cash. You have sold what rose and bought what fell, in small, cheap trades. That is the whole discipline.

Why property is not one of the four

It is lumpy. A S$1.2m condo is one asset. You cannot sell 3% of it to rebalance. The only exits are selling the whole thing or borrowing against it.

It is leveraged. A first home can be financed up to 75% of its value with a bank loan. The Permanent Portfolio is normally held without debt.

It is costly to trade. Singapore taxes the act of buying and selling:

A portfolio you rebalance once a year cannot sit on costs like those.

The leverage arithmetic

A common pitch says that borrowing five times your cash turns a 6% property return into 30%. Two things are wrong with it. The most you can borrow on a first home is 75% of the price, so the home is at most four times your own money before costs, not five. And borrowing is not free.

Say you are a citizen buying your first home for S$1,000,000 with no other loan. You put down 25%, or S$250,000, and pay S$24,600 of BSD. Your cash stake is S$274,600. We leave out legal fees, which would raise it slightly.

Price changeGain or lossOn your S$274,600
+6%+S$60,000+21.8%
+10%+S$100,000+36.4%
−10%−S$100,000−36.4%
−11.6%−S$116,000−42.2%

These figures leave out loan interest (about S$15,000 in the first year on S$750,000 at 2.0%, the low end of fixed packages quoted after the September 2026 Fed hike, and offset by the rent you would otherwise pay), maintenance and agent fees. Leverage works both ways. The last row uses the 2013 to 2017 fall described below. On top of that, you still owe the full loan, and if you must sell within four years you also pay SSD.

Singapore property is not a smooth ride

URA’s all-residential price index, published on data.gov.sg, shows how uneven the path has been:

  • It fell from 154.6 in Q3 2013 to 136.6 in Q2 2017, a drop of 11.6%. It did not pass the old peak until Q4 2020 (157.0), more than seven years later.
  • It fell from 129.7 in Q2 1996 to 71.5 in Q4 1998, about 45%.
  • Over the ten years to Q2 2026 it grew about 4.6% a year (140.0 to 219.4), before rent, stamp duties and other costs.

URA’s flash estimate for Q3 2026 showed private prices up 1.4% on the quarter. Our guide on whether prices always go up covers the long record in more detail.

How the two can sit together

Nothing here says you must choose one. It says to count your assets as they really are.

Count your home as its own big position. Say you own a S$1.2m condo with a S$700,000 loan. Your equity is S$500,000. You also hold S$300,000 in liquid savings and investments, and you put those in a Permanent Portfolio. Your home equity is still 62.5% of the S$800,000 total (leaving CPF aside). The portfolio spreads the liquid part. It does not spread the whole.

Keep liquid money for the loan. If you lose your job, a mortgage keeps running. Cash and other liquid slices pay the instalments without forcing a sale. Our piece on unemployment and property risk explains why this matters.

Get property exposure without the lumpiness. Listed REITs let you hold property income in small amounts, and you can sell part of a holding. They trade like shares, so they carry share-market risk. See REITs versus physical property for the trade-offs.

Remember CPF. Your CPF savings already work like a low-risk slice. The Ordinary Account earns 2.5%, and the Special, MediSave and Retirement Accounts have a 4% floor, which the government has extended to 31 December 2027.

Is a Permanent Portfolio right for you?

Ask yourself:

  • Horizon. The idea is a long-term holding. A short test period tells you little.
  • Tolerance for paper losses. One slice will always be down. Can you hold it through a bad year, and rebalance into it?
  • Your existing property bet. The more of your net worth sits in your home, the less the portfolio changes your overall risk.
  • Your tax and cost position. Rebalancing trades cost money. Check fees before you start.

This is general information, not personal advice.

Bottom line

The Permanent Portfolio is built for low volatility and easy rebalancing. Property is the opposite: large, indivisible, leveraged and heavily taxed on the way in and out. Neither is wrong. Know which one you are doing, look at the whole of your balance sheet, and do not let a 30% headline return from borrowed money hide a 40% loss in the bad years.
