Ever tried to sell something valuable only to realize there’s literally no place to list it? That is the vibe of a non marketable security. It’s wealth, sure. It’s a real asset on a balance sheet. But you can't just hop onto Robinhood or E*TRADE and offload it for cash in three seconds.
Financial markets are usually obsessed with liquidity. Everyone wants to know how fast they can "exit" a position. But a massive chunk of the world’s actual wealth is tied up in things that are purposefully, or sometimes legally, stuck. We’re talking about U.S. Savings Bonds, private placements, and those "restricted" shares that tech founders hold while they’re waiting for an IPO lock-up period to end.
Honestly, it’s a bit of a headache for regular investors. If you own a non marketable security, you’re basically holding a "IOU" from a government or a company that says, "I'll pay you eventually, but don't try to trade this to your neighbor in the meantime."
Why Non Marketable Securities Are Different
The biggest distinction here is the secondary market. Or, more accurately, the total lack of one.
When you buy a share of Apple or Tesla, you’re buying a marketable security. There’s a digital floor—the Nasdaq or the NYSE—where millions of people are screaming (digitally) to buy or sell that exact same thing. The price flickers every millisecond.
A non marketable security is the polar opposite. There is no exchange. No ticker symbol. No flashing red and green lights.
Take the U.S. Series I Savings Bond. It’s incredibly popular right now because of how it handles inflation. But you can’t sell it to a buddy. You can’t trade it for Bitcoin. You have to go back to the source—the U.S. Treasury—to get your money back. And even then, they might make you wait a year before you’re even allowed to ask.

The Liquidity Trap
Liquidity is just a fancy word for "how fast can I turn this into a sandwich?"
Cash is the ultimate liquid asset. A house is illiquid. A non marketable security sits in this weird middle ground where it has a guaranteed or calculated value, but your hands are tied. This creates what's known in the industry as a "liquidity discount." Basically, if you were somehow able to sell a non marketable asset on a private market, you’d have to sell it for less than it’s "worth" just because the buyer knows they’re going to be stuck with it too.
The Big Players: What Actually Counts as Non Marketable?
It isn't just one type of paper. It’s a whole spectrum of financial instruments that serve very different purposes for the government and big corporations.
- U.S. Savings Bonds (Series EE and I): These are the classics. Your grandma probably gave you one for your birthday in a card that smelled like peppermint. You can't sell these to anyone else. Period.
- State and Local Government Series (SLGS): These are niche. Usually, it's just local governments buying these from the feds to park money they got from issuing municipal bonds.
- Private Placement Stock: When a startup raises money from "angel investors" before they go public, those investors get shares. But those shares aren't on an exchange. They are non marketable until the company hits the stock market or gets bought out.
- Restricted Stock: Sometimes, high-level executives get paid in shares. To stop them from dumping all the stock and tanking the price, the company puts a "restrictive legend" on the certificate. It’s effectively non marketable until a specific date or event happens.
The Secret Advantage of Being "Stuck"
You might wonder why anyone would want an asset they can't sell. It sounds like a trap. But for the U.S. Treasury, non marketable debt is a superpower.
When the government issues Treasury Bills (T-Bills) on the open market, the price fluctuates based on what the Federal Reserve is doing or how scared people are of a recession. It’s volatile. But when the government issues non marketable securities to its own agencies—like the Social Security Trust Fund—it doesn't have to worry about market panics.
It’s stable. It’s predictable.

For the individual, the benefit is usually "forced discipline." You can't panic-sell your Series I bonds during a market crash because you literally can't sell them at all. It protects the investor from their own worst impulses. Plus, these securities often come with tax perks that "normal" stocks don't have.
Tax Nuances and the IRS
Because you can't trade these, the way they are taxed is often different. You aren't dealing with capital gains in the traditional sense because there's no "sale" in a marketplace. Usually, you’re looking at interest income. For some government bonds, you might even be able to defer that tax for decades until you finally cash out.
Risks Nobody Mentions
If you’re holding a non marketable security, you aren't worried about a "flash crash." You’re worried about opportunity cost.
Imagine you have $50,000 locked in a non marketable bond paying 3%. Suddenly, the world changes and you can get 8% somewhere else. If that were a regular bond, you might sell it (even at a loss) to chase the higher return. With a non marketable asset, you are often just... stuck. You watch better opportunities sail by while your money is held hostage by a contract you signed three years ago.
There is also the "valuation" nightmare.
How much is a private company worth? If it's not traded on an exchange, you’re basically guessing. You have to hire expensive appraisers or use complex formulas like the Discounted Cash Flow (DCF) model. It’s not like looking at your phone and seeing "AAPL: $190." It’s more like, "Well, based on the last round of funding and the current EBITDA multiplier in the SaaS sector, we think it's worth $12.50 a share... maybe."

Moving From Non Marketable to Marketable
The "Exit." That's the dream.
For a startup founder, the goal is to take their non marketable private shares and turn them into marketable public shares via an IPO. This is the moment of alchemy where "paper wealth" becomes "real wealth."
But even then, it’s not instant. The SEC has rules—specifically Rule 144. It dictates how and when you can sell restricted or control securities. Even after a company goes public, insiders might have to wait 180 days (the lock-up period) before their shares lose that "non marketable" status.
What You Should Do Next
If you find yourself holding assets that you can't easily sell, don't panic, but do get organized. Here is how to handle a non marketable security without losing your mind:
- Locate the Transfer Agent: Since there's no exchange, there is always a "transfer agent" or a specific government portal (like TreasuryDirect) that keeps the official record of your ownership. Find out who they are.
- Check the Maturity Date: Most non marketable instruments have a "shelf life." Know exactly when your lock-in period ends. Mark it on a calendar.
- Read the "Hardship" Clauses: Some non marketable assets, like certain annuities or restricted funds, have "emergency" exit hatches. They’ll charge you a massive fee (surrender charge), but if you’re in a total bind, it’s good to know the door exists.
- Balance Your Portfolio: Never put all your money into non marketable assets. You need "dry powder"—liquid cash or stocks—that you can grab in an instant. A good rule of thumb is to keep at least 3-6 months of expenses in a purely marketable, liquid form.
Non marketable securities aren't "bad" investments. They are just slow ones. They are the crockpots of the financial world—set them, forget them, and wait a long time for the result. Just make sure you have a microwave (cash) ready for when you’re actually hungry.
