Definition ∞ Sustainable asset yield refers to the consistent and long-term generation of returns from digital assets without jeopardizing their underlying value or the stability of the system. This yield is typically derived from legitimate economic activities within decentralized finance (DeFi), such as lending, staking, or providing liquidity, rather than speculative or unsustainable token emission models. It implies a yield that can be maintained over extended periods, supported by genuine demand and utility within the protocol. Identifying truly sustainable yields is crucial for investor confidence and ecosystem health.
Context ∞ News often discusses sustainable asset yield in the context of DeFi protocols, contrasting it with excessively high, often temporary, yields that frequently precede market corrections. A key debate involves distinguishing between legitimate, economically sound yield generation and Ponzi-like schemes reliant on new capital. The pursuit of sustainable yield is a central concern for long-term investors and the overall maturity of the decentralized finance sector.
