## Pool-Based Price Impact

Pool-based price impact refers to the change in the execution price of an asset when a trade is executed against an automated market maker liquidity pool. Because these pools use mathematical formulas to determine prices, every trade consumes a portion of the available liquidity, which shifts the ratio of assets in the pool.

A larger trade size relative to the total pool size results in a more significant shift in the asset ratio, leading to a higher realized price for the buyer or a lower realized price for the seller. This phenomenon is a direct consequence of the constant product formula or similar automated market maker mechanics.

It serves as a cost that traders must account for when entering or exiting large positions. Unlike traditional order books where depth is visible, pool-based impact is deterministic based on the current pool state.

Minimizing this impact often requires splitting trades or utilizing liquidity aggregators. Understanding this mechanism is essential for efficient trade routing in decentralized finance.

It is a fundamental aspect of market microstructure in the context of permissionless liquidity.
