ACH Banking rules were changed to Same Day clearing and settlement in September 2016. PayPal has no choice in the matter, and therefore is unable to choose a slower method even if they wanted to. “[Same Day ACH] will build upon existing, next-day ACH Network capabilities and establish a new option for same-day clearing and settlement via ACH. Under the Rule, two new same-day settlement windows will be added to the ACH Network, increasing the movement of funds between financial institutions from once each day to three times each day. The Rule also requires that all Receiving Depository Financial Institutions (RDFIs) receive same-day transactions and provide faster funds availability to customers, creating value for end uses through its reach to all bank accounts and ability to give consumers and businesses a new option to quickly pay bills and receive funds faster.” PayPal is just not posting the transfers in a timely manner, and holding customer's money for up to 8 days for their own use. Moving towards same day ACH is scheduled to start in September 2016.
