Dear Reader,
There is an old saying on Wall Street: “In a crisis, all correlations go to one.”
Most people hear that and nod politely. Few understand what it actually means for their savings.
Here is what it means. In normal times, your stocks move one way, your bonds another, your real estate another. They don’t march in step. That gap between them is what people call “diversification.” It is the whole idea behind the modern portfolio — spread your risk across different assets, and when one falls, the others hold you up.
It sounds smart. It even works right up until the moment it doesn’t.
Economists measure how closely two assets move together using a number called correlation. It runs from -1 to +1. A correlation of +1 means two assets move in perfect lockstep — if one goes up 5%, the other goes up 5%. A correlation of -1 means they move in perfect opposition. A correlation of zero means they’re independent of each other.
In the real world, nothing is that clean. But here is a useful example. Think about an oil company like ExxonMobil and a consumer staples company like Procter & Gamble — the people who make Tide detergent and Gillette razors. Their correlation is somewhere around 0.3.
What does that mean in plain English?
It means they mostly do their own thing. When oil prices surge and ExxonMobil climbs, Procter & Gamble may not move much at all. After all, people buy soap and razors no matter what crude oil costs. Some weeks they move together, some weeks they don’t. The connection is loose and unreliable. That looseness is exactly what makes owning both of them safer than owning just one.
A correlation of 0.3 is what diversification is built on. It’s what your advisor is betting on when he tells you your portfolio is “balanced.”
The problem is that 0.3 is a peacetime number.
The Moment the Safety Net Disappears
When real fear (not a little dip) hits a market, something ugly happens. All those “different” assets start moving the same way. Down.
In calm times, the average correlation between two stocks is about 0.3. Low enough that owning both gives you some protection. In a full panic, that number jumps to 0.7 or higher. Bonds, commodities, and real estate all start falling in step with stocks, too.
Your carefully built portfolio, the one your advisor told you was “diversified,” starts sinking like a single ship.
Why does this happen?
Because the big players aren’t selling by choice, they’re selling because they have to.
Hedge funds get margin calls. Banks hit their risk limits. Mutual funds face a wave of redemptions — people pulling money out all at once. These institutions don’t get to sell what they want. They sell what they can. And what they can sell is whatever is large and liquid enough to find a buyer — the biggest stocks, bond ETFs, and yes, even gold and long-term Treasuries.
This is what traders call the “dash for cash.” In that phase, no one cares about long-term value. They want dollars. Safe, liquid, boring dollars. And to get them, they dump everything else.
Even Your “Safe” Stuff Can Drop First
Many investors think they are protected because they own gold or government bonds. In the first leg of a panic, that comfort is a lie.
In 2008, gold fell more than 30% at one point. Not because gold was bad. Because big players needed cash, and gold was one of the few things that still had buyers. In March 2020, stocks fell. Corporate bonds fell. Gold fell. Even many government bonds fell. All at once. All for the same reason.
The system wasn’t broken. It was working exactly as a leveraged market works. When you owe money right now, you don’t think about what an asset is worth in five years. You think about what it will sell for in the next five minutes.
This is the part that surprises people. Safe havens aren’t safe on Day One. They are safe across the full arc of a crisis — after the forced selling stops and the real story takes over.
Take gold. Yes, it can get hit hard in the initial panic. But once the dust settles and central banks start cutting rates and printing money — which they always do — gold tends to shine. It finished 2008 up about 10% for the full year, even after that terrifying mid-year drop. It surged after the dot-com bust. It ran hard after the Great Recession.
The pattern is clear: gold gets sold first, then bought hard.
What Has Actually Worked
If everything falls together in a crisis, what actually holds up in the worst of it?
Two things: cash and short-term Treasury bills.
Not long-term bonds, as those can fall sharply when interest rates spike. Not money market funds that own risky debt. Plain cash and T-bills: the kind of money that is there, that is safe, and that no one is forced to sell.
T-bills have almost no interest-rate risk. The U.S. government backs them. You can turn them into cash fast. During recent bouts of market chaos, when stocks and long bonds both fell, T-bills barely moved.
Think of it this way:
T-bills help you survive the crash. Gold helps you survive the money printing that comes after.
Both have a role. Neither one alone is enough.
What to Do Now
We have a war. We are seeing rising tensions across the Middle East. And we have a stock market that, as of this writing, is still priced for a world where none of that matters much.
That gap between what is happening and what markets are pricing won’t last forever. It never does.
Here are the moves worth making now, while you still can:
Build a real cash buffer. Several months of living costs, in actual cash or T-bills, not in some “safe” fund that quietly owns risky long-term bonds. This is what keeps you from becoming a forced seller.
Shorten your bond exposure. If you hold bonds, lean toward short maturities. Long-term bonds can fall just as hard as stocks when rates spike. We have seen it happen.
Split your money into two buckets. Survival money — cash, T-bills, maybe some physical gold. And risk money — stocks, real estate, longer bonds, anything that can swing around. Know which is which. Keep them separate in your head and in your accounts.
Hold gold as insurance, not as a trade. A modest, steady slice of gold isn’t a bet on the next headline. It’s long-term protection against what almost always follows a major crisis: governments printing money to fix the mess they made.
Ask the brutal question. If all your risky assets dropped 30 to 40% at the same time, would you be ruined? If the answer is yes or even maybe, cut your positions now while markets are still open and buyers still exist.
Avoid leverage. The “dash for cash” is driven by people who borrowed too much. Don’t be one of them. Margin debt turns a bad drawdown into a wipe-out.
Wrap Up
To be sure, I don’t want you to panic. I’m merely trying to imitate the great Wayne Gretzky by skating to where the puck will be, so to speak, in six months. Then, I think the ripples, waves, and tsunamis from this incursion into Iran will be upon us, rather than some abstract thought experiment.
When that next wave hits, most people will be shocked to learn their “diversified” portfolio was the same trade all along.
But not you. You already know better. The question is whether you act on it.
All the best,
