Yu’e Bao / 余额宝

Yu’e Bao / 余额宝 is the opening product case in vol.101.既安全、收益又高、流动性还好的投资到底存在吗？. The episode uses it to show how an asset can look unusually attractive when return, perceived safety, and liquidity line up with the surrounding interest-rate environment and payment behavior.

In the source’s account, Yu’e Bao once offered roughly 4%-5% annualized yield, had the perceived safety of a money-market fund, and connected investment balances to daily electronic payment. Later, as underlying yields fell and regulatory constraints mattered more, the same product became less compelling as a deliberate investment destination.

Key Claims

• The product’s investment meaning changed with the rate environment rather than with its name alone.
• Its original appeal came from the combination of visible daily income, convenient payment use, and perceived low risk.
• It illustrates why Investment Impossible Triangle analysis is relative: a yield that once looked attractive can become weak when rates and alternatives shift.
• It also illustrates Investment Liquidity Tradeoff because payment-linked liquidity made money feel both invested and immediately usable.

Connections

• Investment Impossible Triangle — the product is used to introduce return, safety, and liquidity.
• Investment Liquidity Tradeoff — payment-linked liquidity is the product’s distinctive feature in the source.
• Asset Allocation and Investment Risk Management — broader frameworks for deciding whether a cash-like product deserves a role.
• Asset Scarcity Premium — adjacent idea that some attractive products depend on time-specific windows rather than permanent superiority.
