Quoting from the article: "Paying interest on reserves breaks the link between the quantity of reserves and banks' willingness to lend.
By raising the interest rate it pays on reserves, the central bank can increase market rates and slow the growth of bank lending and economic activity without changing the quantity of reserves. In other words, paying interest on reserves allows the central bank to follow a path for short-term interest rates that is independent of the level of reserves. By choosing this path appropriately, the central bank can guard against inflationary pressures even if financial conditions lead it to maintain a high level of excess reserves."
"This logic applies equally well when financial conditions are stable. A central bank may choose to maintain a high level of reserve balances in normal times because doing so offers some important advantages, particularly for the operation of the payments system. For example when banks hold more reserves they tend to rely less on daylight credit from the central bank to make their payments. They also tend to send payments earlier in the day, which reduces the likelihood of a significant operational disruption or of gridlock in the payments system. To capture these benefits, the central bank may opt to create a high level of reserves as part of its normal operations, again using the interest rate it pays on reserves to influence market interest rates."
Nowhere in the article is there any mention of where the funds would come from or what is implied in the banks receiving the interest payments. Frankly I'm appalled at the flimsy rationale given for maintaining a large supply of excess reserves considering the free lunch that banks will enjoy and its effect on the government's budget deficit. That lunch would be generous indeed if monetary policy called for raising the Fed funds rate to say 10% with about 1 trillion$ of reserves in the system. That would be 100 billion$ of free lunch for banks and that much additional budget deficit.What do you think?
