Premium
In simple terms
The upfront cost you pay to buy the right to trade a crypto asset at a set price in the future. Think of it like paying for insurance—you're paying now for the option to make a deal later.
Definition
The price paid to buy an options contract.
In depth
The market price of an options contract that grants the buyer the right, but not the obligation, to buy (call option) or sell (put option) an underlying cryptocurrency at a predetermined strike price before expiration. The premium is determined by factors including the underlying asset's volatility, time to expiration, moneyness (relationship between strike price and spot price), and market demand for that specific contract. Sellers of options receive the premium as compensation for taking on directional risk, while buyers pay it as the maximum loss on their position if the option expires worthless.
How does Premium work?
The premium is the price the buyer pays the seller when a contract is opened, and it transfers immediately. It has two components: intrinsic value, the amount by which the option is already in the money, and time value, which covers the remaining chance of it moving further in. Time value depends mainly on how long is left and on implied volatility, and it shrinks toward zero by expiry. Premiums are quoted per unit of the underlying, so the total cost is the quote multiplied by contract size, and they move continuously with the market until settlement.
An example
Illustrative figures: a call struck at $4,000 trades at a $250 premium while the underlying is at $4,100. $100 of that premium is intrinsic value, the amount the option is already in the money, and the remaining $150 is time value. If the underlying is still $4,100 at expiry, the time value has gone and the contract settles for $100 — the buyer paid $250 for it and is down $150.
Figures are illustrative only.
What beginners get wrong
- Premium goes to the option seller and is not recoverable, unlike margin, which is collateral that can come back to the account.
- A low premium generally signals a small chance of payout or very little time remaining, rather than an underpriced contract.
- Quotes are per unit of the underlying, so multiply by contract size before assuming what a position actually costs.
- Overlooking the bid-ask spread matters in thin crypto options markets, where buying and selling prices can differ noticeably.
