What Is Open Interest (OI) in Crypto

Key Takeaways

• Open interest (OI) is the total number of outstanding contracts in derivatives markets.
• It reflects market liquidity and helps measure market sentiment or potential price movements.
• OI is influenced by factors such as economic indicators, market liquidity, and regulatory changes.
• OI can also be subject to manipulation through practices like wash trading and spoofing.

Open interest (OI) in the cryptocurrency market is a key indicator that shows the total number of outstanding derivative contracts for different underlying assets, such as Bitcoin or Ethereum. This count includes various types of contracts, like futures and options. Open interest helps traders measure market activity and sentiment by revealing how many contracts are active and not yet settled.

Understanding open interest can be challenging without previous knowledge of traditional or decentralized finance (DeFi). Yet, it is an essential tool that provides deep insights into market conditions, indicating whether the market is bullish or bearish and aiding in making informed decisions.

This article will detail what open interest is in the crypto field, how to calculate it, and the factors to consider. It will also clear up common misunderstandings related to trading volume and price volatility, among others.

Open Interest in Crypto Explained

To explain clearly what open interest in crypto is, it can be useful to think of a particular example, like an imaginary cryptocurrency exchange with no existing Bitcoin futures contracts. 

Then, five traders (A, B, C, D, E) start to change the scenario:

• Trader A decides to buy 10 Bitcoin futures contracts. 
• Trader B sells those 10 contracts.

As a result, they create 10 contracts, and the open interest is 10. 

• Later, trader C buys 5 contracts.
• And trader D sells 5 contracts. 

As a new result, they create 5 new contracts, and the open interest increases to 15 because these are newly opened positions. 

• Furthermore, trader A decides to sell 5 of their contracts to trader E who wants to buy 5 contracts. 

In the final result, 5 contracts change hands, but the total number of open contracts in the market remains the same, which does not change the open interest, and it stands at 15.

Open interest can indicate the flow and depth of the market. 

If open interest is rising, more participants are entering the market, which typically increases liquidity and potentially stabilizes the price due to the larger number of active contracts. 

In contrast, if open interest is declining, it could indicate that traders are closing out their positions, which might suggest a decrease in market activity and possibly an upcoming change in price direction depending on other market conditions.

To take it to the real world, in August 2024, following the release of the Federal Reserve’s meeting minutes, open interest in Bitcoin futures and options increased by 5.53%. This rise, likely fueled by expectations of a potential interest rate cut, pushed the total open interest to over $32.34 billion, indicating increased market activity.

A simultaneous rise in open interest and Bitcoin price can often suggest new money entering the market, potentially supporting a price increase. However, it’s important to note that other factors, such as macroeconomic conditions, regulatory developments, and technical analysis, can also influence Bitcoin’s price.

If open interest declines while prices increase, it might indicate that some investors are withdrawing, potentially leading to a future price drop. However, this interpretation should be considered in conjunction with other market indicators and factors.

How Open Interest Is Calculated

Calculating Open Interest is straightforward. It represents the total number of active contracts in a given market at any point in time. When a new contract is created, OI increases, and when a contract is settled or closed, OI decreases.

As in the previous example, if Trader A buys 10 futures contracts from Trader B, Open Interest increases by 10 contracts. If Trader A later sells the same contract back to the market, reducing the outstanding positions, Open Interest decreases accordingly.

The formula for calculating OI:

Open Interest = Total Open Contracts (Buyers) – Total Closed Contracts (Settled positions)

This calculation is commonly used by exchanges to provide daily snapshots of how many contracts remain active, which helps measure market participation.

Factors Affecting Open Interest

There are several factors can influence the movement of Open Interest in the cryptocurrency market:

• Market sentiment: Positive market sentiment can lead to an increase in open interest (OI), while negative sentiment can cause a decline in OI as traders close their positions.
• Liquidity: Higher OI indicates it might be easier to trade contracts without major price impacts, facilitating transactions.
• Expiration dates: As the expiration date of derivative contracts approaches, open interest tends to increase. Traders adjust or close their positions in response to expected price movements.
• Regulation changes: There is a direct correlation between regulatory changes and OI; favorable regulations typically boost OI, whereas adverse regulations can negatively impact it.
• Technological advances: Improvements in blockchain technology, security measures, or innovations in derivatives products can attract more traders to the market, potentially increasing OI. 
• Macroeconomic indicators: International events and news can impact market sentiment and, consequently, affect OI. For example, a drastic change in interest rates can directly affect OI.

Other more specific factors might be portfolio diversification among traders or the risk associated with the counterparty’s ability to fulfill contract obligations. For example, if confidence in counterparties is high, more traders might be willing to engage, increasing open interest and resulting in the opposite effect if the risk is perceived as high. 

Open Interest vs. Trading Volume

It’s important to distinguish between Open Interest and trading volume. They are both different measures:

• Trading volume: It counts the total number of contracts or assets traded within a specific time, often within a single day. 
• Open interest: In contrast, to trading volume, OI it is the total number of active contracts at any given moment.

While trading volume provides insights into market activity for a given day, OI offers a more long-term view. 

A market with increasing OI and trading volume may be experiencing a strong bullish trend, while a market with declining OI but high volume could indicate that traders are closing positions, potentially signaling a reversal or bearish market.

Is There a Relationship Between Open Interest and Price Volatility?

There is a correlation between Open Interest and price volatility. 

• High volatility: Periods of high price volatility can attract more traders seeking to profit from price fluctuations, leading to an increase in OI.
• Excessive volatility: However, excessive volatility might discourage traders, resulting in a decrease in OI. 
• High OI: At the same time, a high OI can indicate a lage number of traders holding positions, which is an important point for understanding market depth and potential future movements.

However, high OI alone is not enough to predict market direction. For this reason, some other factors have been mentioned earlier in this article. 

Some general indicators are the following:

• Rising OI and rising prices: This can signal that the market is gaining strength, and more buyers are entering, pushing prices higher.
• Rising OI and falling prices: This suggests increased short positions, which can lead to pressure to lower the prices.
• Falling OI and rising prices: This indicates traders are closing out positions, possibly taking profits, and a reversal might be imminent.
• Falling OI and falling prices: This could signal that the bearish trend is close to its end, with fewer traders betting on further declines.

Traders should also consider other factors, such as market sentiment, technical analysis, and trading volume, to gain a complete picture. 

Can Open Interest Be Manipulated?

Open Interest is not immune to manipulation despite its strengths as an indicator. The following are some common tactics:

• Spoofing: This involves placing large orders with no intention to execute them, creating a false sense of market activity and influencing prices.
• Wash trading: This involves simultaneously buying and selling the same asset to create artificial volume and liquidity. Wash trading can be achieved using various techniques. 

Both practices can distort OI, making the market appear more active than it is. For this reason, traders should be cautious when interpreting OI, especially in markets with a history of manipulation.

Conclusion

OI in crypto markets is an essential metric that provides traders with insights into market depth, sentiment, and potential price movements. 

Understanding OI, along with other market indicators, can significantly enhance trading strategies. It can reveal trends and shifts in trader behavior and serve extensively as a tool.

 However, traders should also be aware of potential manipulations in OI,and carry their analysis based on multiple factors.
