Bitcoin follows stocks down, and sometimes walks the other way

Quick answer: Crypto moves with stocks when the driver is money and mood: interest rates, liquidity, fear. It moves on its own when the trouble is inside crypto itself, or inside the banks. Don't count on it to zig when your stocks zag.

The week it all sold together

On March 12, 2020, as the pandemic panic hit, Bitcoin dropped by roughly half in about two days. Stocks were falling too. People who'd bought it as "digital gold" found out what it does when everybody wants cash: it gets sold first, because it's easy to sell.

That's the first thing to understand. In a real scramble, investors don't sell what they want to get rid of. They sell what they can get rid of. Crypto trades around the clock, every day, with no circuit breakers and no closing bell. It's the most available thing in the portfolio.

Why they move together

Three reasons, and none of them is mystical.

The same money owns both. For years Bitcoin was held by hobbyists and true believers who didn't care what the Nasdaq did. Then the SEC approved spot Bitcoin ETFs in January 2024, and now it sits inside brokerage accounts next to tech stocks. A fund manager told to cut risk by ten percent doesn't distinguish between asset classes the way a believer does. It's all one risk budget.

Cheap money lifts everything speculative. When the Fed holds rates near zero, safe yields are worthless and people reach for anything with upside. Bitcoin hit roughly $69,000 in November 2021. Then the Fed started raising rates in March 2022, and Bitcoin fell by about three quarters by year's end. The Nasdaq Composite lost roughly a third that same year. Different sizes, same direction, same cause. If you want the plain mechanics of what rate changes do, this piece covers it.

Borrowed money makes it worse. A lot of crypto trading runs on leverage, meaning traders put up a little and borrow the rest. When the price dips, exchanges automatically close those positions, and that forced selling pushes the price down further, which closes more positions. Stocks have margin calls too, but crypto's version is faster, runs all weekend, and has fewer adults in the room.

Why a Saturday matters

Here's an annoying detail most explainers skip. The stock market closes Friday afternoon. Crypto doesn't.

So when bad news lands Saturday night, crypto is the only major market open to react. Sometimes it drops Sunday, and the stock market opens Monday and catches up. Other times crypto overreacts, and Monday corrects it. If you check your portfolio on a weekend and panic, you're often looking at a market that's reacting alone, in thin trading, with nobody else to tell it to calm down.

When it walks the other way

Correlation isn't a law. It's a habit, and habits break.

Crypto-specific events. In November 2022, FTX, one of the biggest exchanges, collapsed. Bitcoin sank to around $16,000, and the damage hit nearly everything in crypto. Stocks finished that month higher. The cause was inside crypto, so the effect stayed inside crypto. Same logic runs the other way. The ETF approval in 2024 was a crypto story, not a stock market story.

Trouble in the banks. In March 2023, Silicon Valley Bank failed, and regional bank stocks got crushed. Bitcoin rallied from around $20,000 to above $28,000 in the weeks that followed. The "money that doesn't need a bank" argument finally got an audience. Worth noting that this lasted a few weeks, not years, and plenty of other things happened that spring too. One example isn't proof. But it's the clearest case for the original idea behind the coin: if you worry about the system, you want something outside it.

Its own supply story. Bitcoin's issuance is fixed by code. When the market decides that matters, it can trade on scarcity rather than on the Fed. That's rarer than the believers admit.

What this means for your money

The correlation isn't a reason to sell. It's a reason to be honest about what you own.

• You may be holding the same bet twice. A portfolio of tech-heavy stocks plus crypto looks diversified on a screen. In a bad month, it behaves like one position. Diversification means holdings that disagree. In a panic, these tend to agree.
• Check it against your own history. Pull up your account for the last real drop, whether that was 2022 or last April. See what each holding did. That's worth more than any article, this one included.
• Don't buy it as a hedge. If you want protection when the system wobbles, look at what has actually held that role over centuries. Gold and silver have a much longer record, with their own limits. Bitcoin has about fifteen years of data. That's not enough to promise anything.
• Size it so a 50 percent drop doesn't change your life. It has happened more than once, and it will happen again. If a halving of this position would force you to sell something else, or cost you sleep, it's too big.
• Debt first. Credit card interest is a guaranteed loss. No coin reliably beats it.

The concession: some sensible people hold crypto precisely because it can fall alongside stocks and still be worth owning, since they're betting on the long run and they have decades. That's a coherent position. It just isn't the same as hedging.

Our take

This is commentary, and it's ours. The idea behind Bitcoin is a good one, and it's the reason we care. Money that no government can print more of, that you hold yourself, with no permission slip from a bank. That's a liberty argument and a self-reliance argument, and we like both.

But liberty doesn't repeal arithmetic. Until a lot more of the world holds Bitcoin for those reasons, it'll keep getting priced by the same crowd that prices everything else, and that crowd sells in a panic. Own it for what it might become. Don't pretend it's a shock absorber today.

Some of the worst losses come from people who thought they were protected, so keep your guard up on the scams that catch careful people too. A calm portfolio and a clear head beat a clever theory.
