Understanding Loss vs. Rebalancing (LVR) in DeFi: An Insight Article by Private Pools Network
Introduction
Educating our community on the technical nuances of our market vertical is essential for maximizing the benefits offered by our protocol. In today’s article, we dive into “Loss vs. Rebalancing” (LVR).
DeFi protocols, particularly Automated Market Makers (AMMs), face significant challenges in optimizing their liquidity environments, including impermanent loss and toxic order flow. LVR is a critical concept for assessing these challenges, playing a vital role in liquidity management, particularly for advanced traders and liquidity managers. Unfortunately, many retail liquidity providers remain unaware of LVR — until now.
The Hidden Cost of Liquidity Provision
Yield farming often promises lucrative returns through liquidity provision (LP), acting as trading capital for buyers and sellers. However, hidden costs stemming from inefficiencies in the AMM model can erode these returns, a fact often overlooked by retail DeFi users. One such cost is Loss Versus Rebalancing (LVR), a metric for understanding the true profitability of liquidity provision in AMMs. This article aims to demystify LVR, explain its significance, and explore potential solutions to mitigate its impact.
What is Loss Versus Rebalancing (LVR)?
Essentially, LVR measures the cost incurred by Automated Market Makers (AMMs) due to ‘information asymmetry.’ In this context, information asymmetry refers to situations where informed traders, who have access to more accurate or timely market data, exploit price discrepancies between AMMs and centralized exchanges (CEXs). This leads to unfavorable trading outcomes for AMMs as these traders capitalize on these discrepancies before the AMMs can adjust their prices. The result is a situation where the costs incurred by AMMs to maintain pool balances, often paid out in the form of arbitrage profits, can exceed the fees collected from trading volumes, diminishing the overall profitability for liquidity providers.
This concept is central to how Private Pools Network extracts liquidity yield for our Private Index Pools (PIPs).
Defining Information Asymmetry
Information asymmetry occurs when one party in a transaction has more or better information than the other. In the context of DeFi, this typically refers to situations where traders or arbitrageurs have access to more up-to-date or accurate information about market prices compared to liquidity providers (LPs) in AMMs.
Defining Adverse Selection
Adverse selection refers to a situation where one party in a transaction takes advantage of another party by exploiting an information advantage, leading to an imbalance in the transaction. In traditional finance, it often occurs when buyers or sellers have more information about a product or asset than the other party, leading to unfavourable outcomes for the less-informed party.
In DeFi, adverse selection can occur when informed traders consistently exploit liquidity pools because they can predict or know market movements before the AMM can adjust its prices. This consistent exploitation leads to losses for LPs because they are always on the “losing” side of trades that are executed at unfavorable prices.
The relationship between information asymmetry and adverse selection is one of cause and effect. Information asymmetry often leads to adverse selection, where the imbalance in information results in suboptimal outcomes for one party, typically the liquidity providers in the context of AMMs.
Understanding LVR is crucial for yield farmers who risk exposing their capital to the negative outcomes associated with traditional AMM environments.
- True Cost Awareness: LVR helps LPs understand the real costs of providing liquidity, accounting for losses due to arbitrage, which traditional metrics like impermanent loss (IL) often overlook.
- Strategic Insight: By understanding LVR, LPs can make more informed decisions about where and how to provide liquidity, leading to potentially more profitable strategies — like those offered by PPN.
- AMM Design: LVR provides insights for AMM designers to structure AMMs that minimize LP losses and make liquidity provision more attractive.
How LVR Works
To grasp LVR, let’s compare two scenarios:
- AMM Liquidity Provision: Suppose you provide liquidity in an ETH-USDC pool on Uniswap. If the price of ETH on CEXs like Binance suddenly increases, arbitrageurs will buy ETH from the AMM at the outdated price, sell it on Binance, and pocket the difference. This scenario exemplifies adverse selection, where LPs incur losses due to arbitrage.
- Rebalancing Portfolio: If you had instead rebalanced your portfolio on a CEX, you would have executed trades at the current market price, avoiding the losses incurred by LPs in the AMM.
LVR is the difference between these two outcomes, highlighting how LPs would have fared better by rebalancing their portfolios on a CEX rather than providing liquidity in an AMM.
The Impact of LVR on LPs
LVR can significantly impact LP profitability due to several factors:
- Price lag: AMMs often trade at worse prices than CEXs due to delayed price updates, leading to value loss for LPs.
- Volatility Sensitivity: LVR is sensitive to market volatility. High volatility increases arbitrage opportunities, leading to greater losses for LPs.
- Informational Disadvantage: LPs are at a constant disadvantage compared to HFTs, who can quickly exploit price discrepancies. LP positions are fixed strategies, while HFTs are dynamic and leverage more accurate price information, resulting in losses for LPs.
Conclusion
Understanding LVR enables liquidity managers to better assess the risks and costs of liquidity provision in DeFi. By measuring the costs faced by LPs due to adverse selection, LVR offers valuable insights into the challenges introduced by information asymmetry and price slippage.
As DeFi liquidity environments evolve and deliver new product suites concerning liquidity management, understanding and mitigating LVR will be crucial for both LPs and AMM designers.
