Thanks, Brian. That cleared some things up for me.
I'm still weak in at least two areas though:
First, let me get this straight: With QE, the Fed has bought assets with newly printed (or electronically created) money to inject reserves into the system...and with IOR, the same banks who sold them these assets can then deposit those same reserves with the Fed for risk-free interest?
You understand the concept and what is happening here, but the terminology/components are not quite correct. The Fed does not buy assets with "newly printed money" to inject reserves into the banking system. The simple act of purchasing those assets injects reserves into the system. When the Fed is engaging in balance sheet expansion and buys treasury securities through a POMO operation, the Fed credits the reserve account of the depository institution that is making the purchase through the primary dealer (if in fact a bank is the buyer). If the primary dealer is not acting as an agent, but for its own account, then the bank account used by the primary dealer is credited (deposit money is created) ... as is the reserves account of that bank at the Fed. Hence, Fed buys securities (asset side of the balance sheet), Fed credits reserves (liability side of the balance sheet). When the Fed creates reserves, it is usually not "printing money" in the sense that people use it. It is always creating base money. But until that base money becomes deposit money, it is not part of money supply.
And regarding your IOR sentence above ... the bank does not deposit those reserves. Those reserves have already been credited by the Fed. And yes, the Fed is paying these banks interest on their reserves. In fact, they do not pay interest for just excess reserves (and just reserves on deposit with the Fed) ... they pay interest on all reserves. This includes required reserves as well as vault reserves.
Granted, the point of IOR is to let the Fed increase the federal funds effective rate when the time comes, so IOR is probably low right now,
The purpose of IOR is to implement monetary policy in this "new normal" of Fed monetary policy. There really is no federal funds rate anymore. The federal funds rate is simply a reflection of the IOR rate. IOR serves as a floor and is at 0.25%. Without IOR, the federal funds rate would be just above zero (and I mean .01% or .001%, etc., not .14%). The reason why the federal funds rate deviates a bit (is a bit below) the IOR rate is because not all institutions with reserves accounts at the Fed are eligible for IOR (only depository institutions are eligible). Think the GSAs (Fannie Mae, Freddie Mac, Ginnie Mae, etc.). These non-depository institutions want to get something for their excess reserves, thus these are the lenders in the now very small federal funds market. They are going to get something for lending out their excess reserves, but probably not 0.25% and certainly not above it (else depository institutions would once again engage in the federal funds market as it would pay more than the IOR rate).
Should the Fed decide to tighten at some point in the future, it would increase the IOR rate. The federal funds rate would simply tag along for the ride and would remain a dinosaur of monetary policy. Think about this ... Excess reserves in the banking system are currently at about $1.5 trillion. If the Fed abandoned IOR, they would have to drain at least $1.2 trillion of those reserves to get any sort of meaningful movement in the federal funds rate. They would probably need to get reserves under $150 billion just to achieve a 1% federal funds rate. And if you recall from my prior articles, even though the Fed has over $1.5 trillion in reserves as a liability, the Fed might not even be able to drain $1.2 trillion in reserves from the banking system.
This is because the selling of its assets might not fetch the $ reserves that were originally created when the assets were purchased (due to interest rate risk and asset risk). That is when it would get really interesting.
but would I be overly cynical by describing this new policy as yet another systemic boon for bankers aside from its stated purpose? (BTW, what money is used to pay this interest? Is it paid from the Fed's balance sheet, or is it just printed up?)
Maybe I am not the right person to ask as I have repeatedly written in my Financial Sense articles that I think this is part of the Fed's plan to stealthily recapitalize the banking system. It takes time, but it is time they have. A long, slow, painful process that benefits the banks.
The interest payments are simply additional reserves credits issued by the Fed.
Second, on a more fundamental level, the operations you describe - aside from quantitative easing - do not appear to explain how the bulk of our monetary base came into existence in the first place, and I'd really like to concretely understand this once and for all. Did it come from the Fed "printing" money to buy Treasuries on the open market? If not, how did it come about?
You are really asking what happened on Day 1, right? To get a fiat currency central bank managed monetary system jump-started, you need to buy an initial round of assets. These assets traditionally fall into two categories ... sovereign debt and Gold. This is how the Federal Reserve system got started. The quality of assets are important because these are the securities that back the currency and money supply. This is why I harp on the declining composition of the Fed balance sheet ... both in terms of asset quality and maturity (asset risk and interest rate risk). Meanwhile, the financial media seems to be fixated on only the size of the balance sheet. Both are important. Agency debt and Agency MBSs, unfortunately, have become a core holding of our central bank. Meanwhile, average duration continues to rise and is at unprecedented levels.
Over long periods of time, the Fed engages in asset purchases (at considerably lower levels than that of post September 2008). These asset purchases increase reserves in the banking system (liability side of the balance sheet) and obviously add to the asset side of the balance sheet. Increased reserves means increased monetary base. Over time, some of these reserves become currency in circulation. These types of systems rely on continued inflation (even if it is modest) to survive. This is how it is achieved. From the period of summer 1996 to summer 2006, the monetary base increased from $443 billion to $804 billion. In 1959 it was $40 billion.
If so, is M0 therefore closely related to the Fed's current balance sheet, even if fluctuating asset valuations preclude exact quality?
Certainly. M0 (Monetary Base) is simply bank reserves plus currency in circulation. M0 is currently at about $2.65 trillion.
I imagine I must be missing something though: If the Fed used to only purchase Treasuries in this way, that would imply that almost the entire monetary base would disappear if the federal government paid back its debt and stopped selling Treasuries,
No, you got it.
If all US treasury debt, Agency debt, and Agency MBSs were allowed to either mature or be repaid, the only core assets remaining would be a small amount of Gold. Much money would be destroyed.
Over time, the Fed deals with maturation of its treasury securities by rolling them over with the US treasury. This is a special part of a standard treasury auction where the Fed exchanges maturing securities for new ones (in equal $ principal amounts). This is the only time when the Fed is allowed by law (Federal Reserve Act) to purchase treasuries directly from the US treasury. Though as I pointed out in my 2009 article ...
Lending a Helping Hand ... the Fed was really violating the spirit of this rule/law by purchasing "on the run" treasuries (treasuries recently auctioned by the treasury and were two young to establish market price in the secondary market).
and it would similarly imply that almost no money existed prior to the government going massively in debt, which obviously isn't true. I'm missing something here ("something" probably means "a lot").
Hopefully I answered that for you above.
Did the Fed ever create new money by purchasing non-Treasury assets outright, even prior to QE?
Gold.
Your posts seem to imply otherwise, so if not, could you point out what I'm missing here? At the very least, I assume I'm missing a lot about the transition from a pre-Fed system to a post-Fed system, if not transitions that occurred under FDR as well, because the Fed presumably never had to "start from scratch."
All systems start from scratch ... but that does not mean that the government did not already have assets to use as backing for the central bank and currency. It did (Gold). The Fed "purchased" them and as such, hold them as asset and liability entries on its balance sheet. The government also issued debt which the central bank purchased.
