Randall Wray on quantitative easing and the accumulation of reserves:

When the Fed buys assets, it purchases them by crediting banks with reserves. So the result of QE is that the Fed’s balance sheet grows rapidly—to, literally, trillions of dollars. At the same time, banks exchange the assets they are selling (the Treasuries and MBSs that the Fed is buying) for credits to their reserves held at the Fed. Normally, banks try to minimize reserve holdings—to what they need to cover payments clearing (banks clear accounts with one another using reserves) as well as Fed-imposed required reserve ratios. With QE, the banks have ended up with humongous quantities of excess reserves.

As we said, normally banks would not hold excess reserves voluntarily—reserves used to earn zero, so banks would try to lend them out in the fed funds market (to other banks). But in the ZIRP environment, they can’t get any return on lending reserves. Further, the Fed switched policy in the aftermath of the crisis so that it now pays a small, positive return on reserves. So the banks are holding the excess reserves and the Fed credits them with a bit of interest. They aren’t thrilled with that but there’s nothing they can do: the Fed offers them a price they cannot refuse on the Treasuries and MBSs it wants to buy, and they get stuck with the reserves.

A lot of people—including policy makers—exhort the banks to “lend out the reserves” on the notion that this would “get the economy going.” There are two problems with that. First, banks can lend reserves only to other banks—and all the other banks have exactly the same problem: too many reserves. A bank cannot lend reserves to your household or firm. You do not have an account at the Fed, so there is no operational maneuver that would allow you to borrow the reserves (when a bank lends reserves to another bank, the Fed debits the lending bank’s reserves and credits the borrowing bank’s reserves). Unless you are a bank, you cannot borrow them.

The second problem is that banks don’t need reserves in order to lend. What they need is good, willing, and credit-worthy borrowers. That is what is sadly lacking. Those who are credit-worthy are not willing; those who are willing are mostly not credit-worthy.

And we should be glad that banks are not currently lending to the [non-credit-worthy]. Here’s why: that’s what got us into this mess in the first place.
