The accurate statement regarding the benefits of the Federal Reserve issuing repurchase agreements (repos) and reverse repurchase agreements (reverse repos) is:
Repos result in a temporary increase in a bank's reserves and maintain liquidity in the banking system. Banks can sell reverse repos back to the Federal Reserve at a higher price in a short period of time.
This statement correctly identifies two key aspects of repos and reverse repos. Repos provide temporary liquidity to banks, while reverse repos allow the Fed to manage the money supply by borrowing funds from banks, which can involve higher pricing in the short term.
