Sarah, there has always been an ATM fee, but it used to be around 12 pesos and just went up. The ATM tells you how much the fee is and then asks you if you want to continue with the transaction before spitting out your cash. It's just like using an ATM from a bank that is not yours in the States - they always charge. But, since you're international, your bank is charging you an additional 1% on top of this not-your-bank ATM fee.
Reputedly CitiBank ATMs do not charge fees... can anyone confirm?
