Some yearn vaults invest in liquidity pools that let users pay 10bps or whatever to trade one stablecoin for another. So the yield comes from that 10bps fee.

The sUSD yVault deposits sUSD into overcollateralized lending protocols and collects interest on loans to other users (who are presumably using Aave or CREAM as places to buy leverage to get super fucking long crypto). So the yield comes from other users paying interest to borrow sUSD.
