Open interest (OI) should always be evaluated against spot depth — not in isolation.

A useful discipline is comparing total open interest to usable spot liquidity within ±0.5-2% of mid-price. If OI materially exceeds the capital required to move spot price within tight bands, the market becomes fragile. Liquidations in derivatives can overwhelm the spot book and trigger cascade volatility.

You should monitor:

• OI-to-spot-depth ratio — is leverage larger than executable spot liquidity?
• OI growth rate — is leverage expanding faster than organic spot volume?
• Funding rates alongside OI — crowded positioning plus elevated leverage increases squeeze risk.
• Liquidation clusters — concentrated levels create volatility magnets.

High open interest is not inherently negative. It becomes risky when leverage meaningfully outscales spot absorption capacity.

Derivatives should be sized relative to the strength of the underlying spot market.
