Ray Dalio, the founder of Bridgewater Associates and one of the world’s best-known investors, has recently warned that financial markets may be approaching a dangerous combination of rising interest rates, excessive debt and a possible artificial intelligence (AI) investment bubble.
One of the more interesting parts of his argument is his warning about the difference between wealth and cash.
Dalio’s point is not that investors should simply sell everything and keep their money in a bank account. Rather, he is warning that when asset prices become very high and investors become heavily invested in those assets, a change in economic conditions can create a sudden need for cash at precisely the time when everybody else is also trying to raise cash.
That can turn what appears to be considerable wealth into a much more difficult financial situation.
Wealth is not the same as money
Imagine that you own shares worth R10 million. On paper, you are R10 million wealthier than someone who has no investments.
But you do not have R10 million in cash.
If you need R2 million to settle a debt, pay tax or meet some other obligation, you have to sell some of your investments to obtain the money. If markets are rising, that may seem straightforward.
The problem occurs when many investors need to do the same thing at the same time.
If buyers become less willing to pay high prices, asset prices can fall rapidly. The R10 million portfolio that looked extremely valuable can suddenly be worth substantially less.
Dalio has repeatedly highlighted this distinction between wealth and money as an important feature of financial bubbles. He argues that bubbles become particularly vulnerable when there are large amounts of paper wealth but insufficient liquidity to support all the claims being made against that wealth.
Why rising interest rates matter
Interest rates are important because they affect the value of almost every financial asset.
When interest rates rise, borrowing becomes more expensive. Companies have to pay more to finance their operations and investments, consumers face higher borrowing costs and governments have to pay more interest on their debt.
Higher interest rates can also reduce the price investors are prepared to pay for shares.
Consider a technology company whose shares are valued on the expectation of very high profits many years into the future. When interest rates are very low, investors may be willing to pay a high price today for those future profits.
When interest rates rise, those future profits become less valuable in today’s money. Investors may therefore demand a lower share price.
This is particularly important for companies whose valuations depend heavily on expectations of future growth rather than current profits.
Why AI has become part of the argument
Dalio’s warning does not mean that he believes artificial intelligence is a bad technology.
In fact, he has made the opposite point: AI could be an enormously important productivity-enhancing technology. His concern is that a genuinely revolutionary technology can still produce an investment bubble if investors become excessively optimistic about how much money will ultimately be made from it.
This has happened before.
The internet transformed the economy, but that did not prevent the dot-com bubble from forming around internet-related companies in the late 1990s. Many investors paid extraordinary prices for companies whose future earnings were highly uncertain.
The technology was real. The investment valuations were the problem.
Dalio sees similarities in the current AI boom. Enormous amounts of money are being invested in data centres, chips, computing infrastructure and AI companies. Much of the spending is being supported by increasingly large amounts of capital and, in some cases, debt.
He has described the current AI market as a “classic bubble” and warned that rising interest rates could be the factor that eventually exposes excessive valuations.
Debt can make the problem worse
Debt is particularly important because borrowing creates an obligation to produce cash in the future.
Suppose an investor owns R10 million worth of shares and has borrowed R5 million against those investments.
If the shares remain worth R10 million, the situation may appear manageable.
But if the shares fall to R6 million, the R5 million debt has not fallen with them. The investor now has only R1 million of equity in the portfolio.
If the lender demands additional security or repayment, the investor may be forced to sell investments. If thousands or millions of investors are experiencing the same problem, those forced sales can push prices down even further.
This is one reason why excessive leverage can turn an ordinary market correction into a much more serious financial event.
The danger of everyone needing cash at once
This is where Dalio’s argument about converting wealth into cash becomes particularly important.
Imagine a market where investors collectively own R100 trillion worth of assets. Those assets may have substantial value when buyers are enthusiastic and credit is readily available.
But if investors suddenly need large amounts of cash to repay loans, meet tax obligations or cover losses, they have to sell some of those assets.
If there are not enough buyers at the previous prices, prices fall.
Falling prices can then create additional reasons to sell.
This can produce a cycle:
- Interest rates rise.
- Borrowing becomes more expensive.
- Investors become less willing to pay high prices for risky assets.
- Asset prices fall.
- Highly leveraged investors need additional cash.
- They sell assets to raise that cash.
- Additional selling puts further pressure on asset prices.
That is the mechanism behind much of Dalio’s concern.
Why this matters to people saving for retirement
The issue is particularly relevant to people approaching retirement.
A younger investor with 20 or 30 years until retirement may have time to recover from a major market decline.
Someone who has recently retired may not have the same luxury.
If a retiree needs R40,000 a month from an investment portfolio and the market falls by 30%, selling investments to fund those monthly withdrawals means selling assets after they have fallen.
This can permanently reduce the amount of capital available to participate in the eventual recovery.
This is why retirement planning is not simply about achieving the highest possible investment return. It is also about ensuring that sufficient money is available when it is needed.
Does this mean investors should sell their shares?
Not necessarily.
Dalio’s argument should not be interpreted as a prediction that every share market will crash or that investors should move their entire retirement savings into cash.
Trying to predict the exact top of a market is extremely difficult.
The more useful lesson is about liquidity and diversification.
Someone who has all their wealth invested in shares, particularly a small number of highly valued technology companies, may have considerably more risk than someone whose wealth is spread between equities, bonds, cash and other assets.
Having some readily accessible cash also means that an investor does not necessarily have to sell shares after a major market decline simply to pay living expenses.
Cash has a cost too
There is an important counterargument.
Holding large amounts of cash can protect an investor during a market crash, but cash can also lose purchasing power through inflation.
If inflation averages 5% a year, R1 million sitting in an account earning nothing would have considerably less purchasing power after ten years.
Cash therefore should not automatically be regarded as a superior long-term investment.
The objective is to have enough liquidity to meet foreseeable needs without unnecessarily sacrificing the long-term growth required to fund retirement.
A more useful lesson from Dalio’s warning
The most important lesson may therefore be less dramatic than “sell your investments and hold cash”.
It is to ask a more fundamental question:
If markets fell sharply tomorrow, would I have enough accessible money to avoid selling my long-term investments at the worst possible time?
For someone approaching retirement, that could mean maintaining a portion of the portfolio in cash or relatively liquid investments to cover near-term spending requirements.
It could also mean reducing excessive exposure to a single asset class, sector or group of companies.
For investors heavily exposed to the AI boom, it may be particularly sensible to consider whether the current value of their portfolio depends on continued exceptionally strong growth in a relatively small number of companies.
The bigger economic picture
Dalio’s warning extends beyond AI.
He believes the world is dealing with a broader debt problem. Governments are borrowing heavily, debt-servicing costs are increasing and higher interest rates make the problem more difficult.
He has recently warned that the United States could face a significant debt crisis within the next few years as debt and interest costs continue to rise.
At the same time, large technology companies are investing enormous sums in AI infrastructure, with some of that investment increasingly dependent on debt financing.
This creates an unusual combination: governments need to borrow, companies need to borrow and investors are paying high prices for assets whose future returns depend on continued economic growth.
If interest rates continue rising, the cost of servicing that debt increases while the valuation investors are prepared to place on future earnings can fall.
What should pension investors take from this?
There is no certainty that Dalio’s prediction will prove correct. Markets can remain expensive for considerably longer than investors expect, and AI may ultimately generate productivity and profits that justify much of today’s investment.
But the underlying principle is worth understanding.
Wealth on a statement is not the same thing as money available to spend.
When markets are rising, the distinction can seem irrelevant. When markets fall and liquidity becomes scarce, it can become extremely important.
For people approaching or already in retirement, the sensible response is not necessarily to abandon growth investments. Instead, it is to consider whether the portfolio has sufficient diversification and liquidity to withstand a significant market correction without forcing the investor to sell long-term assets at depressed prices.
That is ultimately the issue behind Dalio’s warning: the greatest danger may not be that investors have too little wealth, but that too much of their apparent wealth is tied up in assets that may be difficult to sell at the price they expect when everybody wants cash at the same time.
