Stone -- I'm not sure I fully understand your question, but I will make some comments. I'm not an expert on Treasury/Federal Reserve operations, but I know enough about the basic process to see there is a lot of misundertanding and fuzzy thinking about the topic on this forum.stone wrote: HB reader, am I understanding you rightly that the US fiat system is set up such that the commercial banking system has unlimited capacity to create money without ever being at risk of systemic default but that the USG only has as much deficit spending ability as the Fed and the commercial banking system chooses to grant it? The example of the Fed setting up a line of credit to AIG in 2008 shows that the Fed has unlimited ability to create money to bail out financial institutions. BUT the USG unlike AIG etc can not legally get overdrawn with the Fed. If primary dealers and the Fed were to choose not to buy USG bonds or the debt ceiling were not raised, then the USG would just have to lump it or change the law (or use the trillion dollar platinum coin trick???). On a wider level it seems interesting that the USG chose to enact laws in such a way as to give pre-eminance to the commercial banks. Are commercial banks really such trustworthy guardians of the interests of US citizen's?
jmourik's observation of the legal loophole for making platinum coins with unlimited face value does look like a get out of jail free card for the USG if the Fed has a legal obligation to give the USG the same value of bank reserves as the face value the USG engraves on the platinum coin. Is this a widely known loophole?
Despite what you often see written the Federal Reserve (the FED) does not really have the "unlimited ability to create money to bail out financial institutions." Totally aside from the possible inflationary or interest rate effects on the broad economy, every new dollar the FED creates, unless it is directly offset by the corresponding purchase of an asset, reduces their own capital by a dollar. I don't have the figures in front of me, but I know that their balance sheet is already leveraged something like 45 or 50 to one now so there is definitely an operational limit on their capacity to simply print money and use it willy-nilly to bail out financial institutions. The last thing in the world the FED wants to do is destroy their credibility worldwide by becoming insolvent.
What the FED can do virtually without limit is purchase (and thereby monetize) debt, because that expands both sides of their balance sheet equally. For a whole variety of reasons they prefer to have mostly high grade US Government debt (although they can and do buy some other debt on occasion, like the MBS purchased during QE1) as assets on their balance sheet. In fact, this has been their primary monetary policy tool in recent years. Just like with excessive leverage, a large amount of low quality debt on the asset side of their balance sheet would raise questions about their solvency.
Without getting into the details, the FED and primary dealers can't simply refuse to participate in Treasury debt auctions. A primary dealer that refuses to place a market-related bid in the Treasury debt market will be dropped from the primary dealers list. The FED always has to participate in some manner because it acts as fical agent for the Treasury. Whether it is a net buyer or seller of Treasuries depends almost entirely on the FED's current monetary policy goals.
So, no, the system is not set up to somehow favor the commercial banking system over the USG. If one wants to view it in terms of who it favors, it is probably more accurate (in my view) to say that it favors both of those sectors equally over everyone else in the US economy.
