$AAVE V4: how $6 billion of "dead" money can change DeFi yields

#AaveLabs is preparing one of the most pragmatic updates in DeFi — Reinvestment Module in V4. Its goal is simple: to stop losing yield on idle liquidity.

Today, about $6 billion of stablecoins in the protocol are effectively not working, remaining a reserve for liquidity. This is ≈30% of deposits — a colossal inefficiency for a market where every basis point counts.

The new module will allow for automatic allocation of this capital into low-risk strategies: short-term bonds, money markets, or delta-neutral approaches. Importantly, liquidity remains available for withdrawal at any moment.

In fact, $AAVE is trying to create a "minimum risk-free yield" in DeFi, raising the base yield for lenders. Estimates suggest this could provide up to +20–25% relative increase in APY.

But there is a nuance: the module is not yet finally approved and depends on governance. This means that risk management and strategy selection will become a critical point.

If the implementation is successful — Aave could set a new standard for capital efficiency across all DeFi.
