The notion of APY is the real rate of return earned on your investment, taking into consideration the effect of compounding interest. As you can guess from the word “annual”, the interest rate of this investment is then calculated “yearly” or “annually”.
However, the “Current APY” is interpreted as a miniature version of the ordinary APY, that is, the real-time APY, which is calculated using the interest updated every hour instead. Note that incentive fees have been deducted from it.
