What it means
In finance, liquidity is the speed and ease with which you can turn an asset into cash at fair market value. Think of publicly traded shares, which you can sell on your computer in seconds.
On the other hand, a commercial building or a privately held business cannot be sold overnight. If a buyer wants to cash out quickly, they often have to drop the price.
To convince investors to lock away their capital for years, private assets must offer a higher potential return than public ones. This difference in expected return is the illiquidity premium.
It acts as a reward for patience and for bearing the risk that you might need cash urgently but cannot access it. For managers and business owners, understanding this concept helps when evaluating investments.
If you are comparing a liquid investment, like government bonds, to an illiquid one, like buying specialised machinery or acquiring a competitor, you must factor in this premium. The illiquid project should promise higher profits to justify tying up your cash.
Failing to account for the illiquidity premium can lead to poor strategic choices. If an investment ties up your cash for a decade but only yields the same return as a bank savings account, it is a bad deal.
You are taking on extra risk without getting paid for it. Imagine selling a popular smartphone versus selling a custom-built house.
The smartphone sells instantly on the internet for its exact market value. The house takes months to sell, so you might need to drop the price or wait patiently.
To make the house worth the hassle, you expect a much larger profit when it finally sells.
In practice
Real-world examples
Example 1
You invest $50,000 in a startup company. Because you cannot sell your shares easily for at least five years, you demand a projected annual return of 15%, which is much higher than a standard stock market index fund. If the index fund is expected to return 8%, the 7% gap, or $3,500 a year on $50,000, is your illiquidity premium.
Example 2
Your manufacturing business buys a specialised warehouse for $500,000. Because it takes many months to find a buyer for industrial property, you price the required return on this asset to include a healthy illiquidity premium. If a comparable listed property fund earns 6%, you might insist on 9%, which is $45,000 a year rather than $30,000.
Example 3
A venture capital fund invests in private tech firms and targets a 20% annual return. They need this high return because their capital is locked into unlisted companies for a decade before they can cash out. Their own investors accept the lock-up only if the expected return is clearly above what they could earn in a liquid public fund.

The house takes months to sell, so you might need to drop the price or wait patiently. To make the house worth the hassle, you expect a much larger profit when it finally sells.
Formula
Calculation
Illiquidity Premium = Expected Return of Illiquid Asset - Expected Return of Liquid Benchmark
Example: If a private business investment yields 12% annually, and a liquid public stock index yields 8%, the illiquidity premium is 4% (12% - 8%). This 4% represents your extra reward for taking on the risk of not being able to sell quickly.
In dollars, a $100,000 investment earns $12,000 a year in the private business against $8,000 in the index. The extra $4,000 a year is the premium in cash terms, so over a five-year lock-up the investor expects about $20,000 more in total (before compounding). If the investor needs to sell early and must accept a 15% price cut, the $15,000 loss on the original $100,000 would wipe out almost four years of that premium.Case study
Seen in the real world
This is a fictional, illustrative scenario. Oakwood Logistics, a mid-sized transport firm, had $2 million in surplus cash sitting in a low-yield bank account. The finance director proposed two options. Option one was to buy liquid corporate bonds yielding 4% annually, which could be sold tomorrow.
Option two was to acquire a local rival firm's vehicle fleet and client contracts for $2 million, which could not be easily resold and required holding for five years. The board recognised that option two lacked liquidity. To justify the deal, they required a projected return of 10% per year. This 6% difference above the corporate bond rate represented the illiquidity premium.
By factoring this in, Oakwood ensured they were adequately compensated for the risk of tying up their capital. In dollar terms, the bonds would pay $2,000,000 x 4% = $80,000 a year, while the acquisition had to deliver $2,000,000 x 10% = $200,000 a year. The extra $120,000 a year was the board's price for locking the cash away. The finance director also kept a separate cash reserve so that a sudden bill could never force a hurried sale of the fleet.
Watch out
Common mistakes
- Assuming every illiquid asset automatically generates a high return just because it is hard to sell.
- Forgetting to factor in cash flow needs, leading to a crisis where the business is profitable on paper but lacks cash.
- Confusing general business risk with the specific penalty of not being able to sell an asset quickly.
Questions
People also ask
Is the illiquidity premium guaranteed?
No. It is an expected return, not a promise. Illiquid assets can still lose money if the underlying business or property performs poorly.
How do I calculate the right premium for my business?
Look at comparable liquid investments in the market and compare their historical returns against the returns expected from similar illiquid assets.
Does this apply only to physical property?
No. It applies to any asset that is hard to sell quickly, including private company shares, certain bonds, and specialised equipment.
