What is Open Interest (OI)?

Open Interest (OI) is a key options metric that shows the total number of open (active) contracts.

Volume

= What traded today

Open Interest

= What is still open (active positions)

When OI hits records, it usually means: Traders have built large directional exposure, market makers hold larger hedges, and expiry events become more impactful.

2Why Record OI Can Move Markets

In both equity and crypto options, large open interest can create "feedback loops":

Delta Hedging Effect

When price rises and call OI is high, market makers may need to buy underlying to hedge (delta hedging). That hedging can push price further up.

Gamma Effect

The amplifying effect when hedging triggers further price movement is sometimes called a gamma effect.

Pin Risk at Expiry

Near key strikes, price can "stick" or whip violently around expiration. This is one reason why crypto can experience intense moves near large expiry dates.

3What Does It Mean for Stocks & Options?

This crypto options dynamic is very similar to what happens in major equity indices (SPX) around:

Monthly Expiries

Big OpEx Days

Earnings Weeks

High IV Environment

Meme-Stock Squeezes

Call-driven Rallies

So even if your core interest is stocks & options, this story matters because it shows:

  • Options positioning and hedging is now a major force in crypto price action
  • Crypto is increasingly behaving like a volatility market, not just a "spot" market
  • Techniques used in equity options analytics (OI clustering, pin risk, gamma exposure) are migrating to crypto

FAQ

Is record open interest bullish?

Not always. OI includes hedges and market maker inventory, not just bullish bets.

Can high OI cause volatility?

Yes—especially near expiries and key strikes.

What's the difference between OI and volume?

Volume is traded contracts; OI is open contracts.

Why does OI matter more in crypto than stocks sometimes?

Because crypto markets trade 24/7 and can react faster to hedging flows.

Where can I track BTC options OI?

Deribit analytics, CoinGlass, or institutional dashboards.
