Answer:The recent increase in the APY on Ethereum (ETH) is likely due to the anticipation of the upcoming ethPOS merge airdrop. The ethPOS airdrop is an event where users who have staked their ETH in the ethPOS pool will receive rewards in the form of additional ETH tokens. This airdrop is expected to create a surge of demand for ETH, driving up its price and increasing the APY for stakers. As such, many borrowers are likely anticipating the airdrop and staking their ETH in order to receive the rewards. This increased demand for ETH is likely the cause of the recent rise in the APY for ETH.
