Loss-versus-rebalancing (LVR)
Loss-versus-rebalancing (LVR) measures what AMM liquidity providers lose to arbitrageurs who trade against stale pool prices after markets move.
AMM pools only update their price when someone trades. When ETH rises on major exchanges, the pool still quotes the old price until an arbitrageur buys the cheap ETH and sells it elsewhere. Loss-versus-rebalancing, a concept formalised by researchers in 2022, compares an LP's result with a hypothetical portfolio that rebalances to the same holdings at true market prices. The gap is the value systematically handed to arbitrageurs.
LVR gave liquidity providers a clearer way to judge whether fees actually compensate them. Unlike impermanent loss, it grows with volatility and time and does not reverse if prices come back. It drives much of the current DEX design work, from dynamic fees and auction-based arbitrage rights to hooks and order flow auctions that try to return some of that value to LPs.
LVR is a theoretical benchmark that assumes frictionless external markets, so real figures vary with gas costs, block times and how fast arbitrage occurs. It explains why many passive pools on volatile pairs lose money despite high fee income.
Example
After ETH jumps 2% on centralised exchanges, an arbitrage bot buys ETH from a Uniswap pool at the old price within the next block; the profit it books is LVR paid by the pool's liquidity providers.
