Answer:
Increase but the Reserves in the banking system will decrease
Step-by-step explanation:
When the Federal Reserve System buys security from a non-bank public, the payment will be made from the balance with the Federal Reserve system and this will deplete/decrease the balance with the Federal Reserve System but the currency in circulation will increase, this will in effect lead to an increase in the high powered money, because currency in circulation is one of the components of the High powered money.
The high Powered money is also called monetary base. this consists of notes and coins in circulation in the hands of public, and by financial institutions in their vaults and the legal reserve requirement with the Federal Reserve System.
