I just reviewed a very interesting report published by the Bank of Canada on DeFi lending. The main conclusion is that these systems technically work, but there are several details that most users probably aren't considering.

The study focused on Aave V3 and used transaction-level data to analyze how the model actually functions. What they found is that most of the protocol's revenue is concentrated in very few cryptocurrencies, which is an important point if you think decentralization should distribute this more evenly.

The most curious thing is that many users continue to engage in recursive leverage despite over-collateralization requirements. They are basically looking for ways to squeeze more yield out of the system. Liquidations happen in concentrated waves, but here’s the interesting part: their impact on the broader market is limited. This means that when liquidations spike, they don’t necessarily cause the systemic chaos some predict.

Now, the Bank of Canada's analysis is clear on one point: if governance is robust, DeFi loans are operationally viable. But there are real limitations we can't ignore. Capital efficiency remains an issue, the risk of liquidation is real for leveraged users, and systemic vulnerability exists across the crypto ecosystem that is still not fully resolved.

In summary, DeFi works, but it’s not the perfect solution some promise. It’s a system that requires you to know what you’re doing.
