Impermanent Loss Explained for Fund Allocators

Impermanent loss is the most misunderstood risk in decentralised finance, and the one that quietly turns headline yields into disappointing returns. It is the reason a liquidity provider can earn an impressive advertised yield and still end up worse off than if they had simply held the two assets. For any fund considering liquidity provision, understanding it is the difference between a real return and an illusion.

Impermanent loss is the cost of being a liquidity provider, and it is netted against the yield, not added to it. If a manager quotes the yield without it, they are quoting half the equation.Jason Eastman, Director at CV5 Capital

What impermanent loss is

Impermanent loss arises when a fund provides liquidity to an automated market maker, a pool that lets others trade between two assets. The pool automatically rebalances the two assets as their relative price changes, selling the one that rises and buying the one that falls. The result is that, when prices move apart, the value of the liquidity position ends up lower than if the provider had just held the original two assets. That shortfall, relative to simply holding, is the impermanent loss.

Worked example with numbers

Suppose a fund deposits into a pool of two assets, contributing equal values, with one asset priced at 100. If that asset's price doubles to 200, the pool rebalances by selling some of it as it rises, so the provider ends up holding less of the asset that appreciated. When they withdraw, the total value of their position is higher than at deposit, but lower than if they had simply held the original mix and let the winner run. The gap, often a few per cent for a move of this size and far larger for extreme moves, is the impermanent loss. (Figures are illustrative only.)

When it becomes realised

The loss is called impermanent because it can reverse: if the relative prices return to where they started, it disappears. It becomes a permanent, realised loss when the provider withdraws while prices are still divergent. This is the trap, a position can show an attractive yield throughout, and the loss only crystallises on exit, by which point the trading fees earned may or may not have compensated for it. Whether it was worth it is only knowable at the end.

Net of fees: is liquidity provision worth it?

Liquidity providers earn trading fees and sometimes incentive rewards, and the honest question is whether those exceed the impermanent loss over the holding period. For stable, correlated pairs the loss is small and fees can dominate; for volatile, uncorrelated assets the loss can easily swallow the yield. The advertised yield is meaningless on its own. The only figure that matters is the return net of impermanent loss, and a manager who cannot show that calculation does not understand their own strategy.

Reading DeFi yield claims critically

The practical lesson for allocators is to treat any DeFi liquidity yield as a gross figure that must be reduced by expected impermanent loss and risk. On the CV5 digital asset platform, the valuation and reporting framework captures the true economics of liquidity positions, including impermanent loss, so the return shown to investors is net rather than headline; the investment manager retains the strategy.

Frequently Asked Questions

What causes impermanent loss?

Providing liquidity to a pool that rebalances as relative prices change. When the assets' prices diverge, the position ends up worth less than simply holding the original two assets.

Why is it called impermanent?

Because it reverses if the relative prices return to where they started. It becomes a permanent, realised loss only when the provider withdraws while prices remain divergent.

Is liquidity provision worth it?

Only if the trading fees and rewards earned exceed the impermanent loss over the holding period. For volatile, uncorrelated assets the loss can outweigh the yield.
