How Tax Planning Creates Hidden Risks in DeFi Lending Pools

Many crypto investors are using a strategy called buy, borrow, and die to avoid capital gains taxes. Instead of selling appreciated assets like ETH for cash, they deposit those tokens into DeFi protocols as collateral to borrow stablecoins. This allows them to access liquidity while keeping their original investment, effectively deferring their tax bills indefinitely.

While this is a clever way to save on taxes, it creates a fragile situation for DeFi protocols. When the price of the collateral drops, the loan to value ratio climbs quickly. If the ratio crosses a protocol limit, the system triggers a liquidation. This forces the sale of the user's collateral to repay the debt, which can destabilize the lending pool for everyone else involved.

A recent study on the Venus protocol highlights the scale of this issue. Researchers found that about 3 percent of traders experienced defaults during their study period. Unlike traditional banks that can work with clients during market drops, DeFi protocols rely on rigid smart contracts. These programs monitor collateral values continuously and do not care about the borrower's personal tax goals.

This trend shows that tax incentives are influencing how people manage risk in decentralized finance. Borrowers often wait longer to repay their loans to avoid triggering taxable events, which leaves the lending pools exposed to market volatility for longer periods. As more users adopt this strategy, the collective credit risk within these pools remains a factor that traders should watch closely.
