Difference between warrants and calls

Financial derivatives are valuable instruments that allow investors and traders to manage risk and potentially gain profits. Two common types of derivatives are warrants and calls. In this blog, we will delve into the intricacies of warrants and calls, exploring their features, differences, and use cases.

What are warrants?

Warrants are financial instruments that give holders the right to buy or sell an underlying asset at a pre-established price within a specified timeframe. However, there is no obligation on the holder. They can be investment warrants, traded on exchanges, or employee stock options warrants given as part of compensation. While warrants offer potential gains, they come with risks.

What are calls?

Calls, also known as call options, are contracts that give the buyer the right to purchase an underlying asset at a pre-established price within a specific period. However, there is no obligation on the buyer. Like warrants, calls have an exercise price and an expiration date. However, calls differ from warrants in terms of their buyer-seller structure and the underlying assets involved. Understanding the nuances of calls is essential for investors seeking to utilise these instruments effectively.

What are the Key Differences between warrants and calls?

1. Structure and Issuance:

Warrants often originate from the issuer, such as a company or government entity, to raise capital. On the other hand, calls are commonly issued and sold by individuals or institutions who seek to profit from price movements in the underlying asset.

2. Underlying Assets:

Warrants and calls can be associated with various underlying assets, including stocks, bonds, and commodities. However, warrants are typically more flexible and can encompass a broader range of underlying assets compared to calls.

3. Rights and Obligations:

Warrant holders have the right, but not the obligation, to buy or sell the underlying asset at the predetermined price. In contrast, call buyers have the right, but not the obligation, to purchase the underlying asset. Warrant holders have no obligation to take any action, while call sellers have the obligation to deliver the underlying asset if the call is exercised.

4. Risk and Reward:

Warrants and calls differ in price sensitivity, leverage, and potential returns. Warrants can offer higher leverage and potentially greater returns due to their longer expiration dates and lower upfront costs. Calls may have shorter expiration dates and higher upfront fees, but can provide more precise risk management.

Use Cases and Examples

To illustrate the practical applications of warrants and calls, let's consider a few examples:

1. Warrants in practice:

   - A stock warrant allows the holder to purchase company shares at a specific price within a predetermined period.

   - A bond warrant grants the holder the right to exchange the warrant for a bond at a predetermined price.

2. Calls in practice:

   - A covered call strategy involves selling call options on an underlying asset the investor already owns, potentially generating income through premiums.

   - A naked call involves selling call options without owning the underlying asset, which carries higher risks due to unlimited potential losses.


Warrants and calls are essential tools in financial derivatives, providing investors and traders with opportunities for risk management and potential profits. Understanding the primary differences between warrants and calls, including their structure, underlying assets, rights, obligations, and risk profiles, is crucial for making informed investment decisions. By exploring their use cases and examples, investors can gain a deeper appreciation of the practical applications of these derivative financial instruments.
