What is DeFi lending?

Supplying crypto to a lending protocol so borrowers can use it, typically in exchange for variable yield.

Why it matters on your return

The yield is ordinary income, like interest, when it is earned and accessible. Whether the deposit itself is an exchange depends on the receipt token: one-for-one receipts (aTokens) are generally deposits; tokens that represent a claim on a pool of different assets may be exchanges.

Example

You lend 20,000 USDC and earn $900 of yield over the year, reflected in your receipt token balance. The $900 is interest income; no gain arises on withdrawing the USDC.

Is DeFi lending yield taxed like bank interest?

Yes, as ordinary income, but without a 1099-INT. You report it from your own records at the value when earned.
