Where do they get the money to buy their own debt? I get that they can print as much debt as possible, but where do they get the money to buy their own debt? And I assume this obviously means that without the reserve credit, the money supply would grow at a much slower rate.
The government creates debt in the form of bonds. The central bank creates a market for these bonds, by offering to buy them from financial institutions, in return for reserve credit. Reserves are very valuable to banks, because they can use them to loan out up to 10 times as much new money.
Ideally, the money supply does not grow under central command but certainly not in this fashion, where it's government debt which is driving expansion.
I'm a layman, so don't take the next part as gospel. It might not be 100% right.
Say the government runs a deficit of $5. They issue a bond. You, being a patriotic sort, buy the bond. When the bond is due for redemption, the bank buys it from you, and pays you your principal plus interest. The bank then sells the bond to the central bank, in return for reserve credit. The central bank creates the credit it uses to purchase bonds, out of thin air. I then presume the bond is destroyed or redeemed with the government, but since the central bank turns over all profits to the government treasury each year, redemption is the same as destruction. It's moving the bond from one bottomless pocket to another.
The thing about the central bank is, it allows politicians to spend without taxing (by devaluing savings and slowing economic growth), and it enables banks to fractionally reserve, so they can generate massive profits from speculation with almost zero risk. The central bank itself facilitates both parties getting what they want. And in return, the central bank in any country is basically the lifeblood of the economics profession. Most "private" economists work for the central bank, or receive funding from the central bank. They have an interest in supporting the institution, because without it, they would have to chase scarce "real jobs".
I was always under the impression that the main way the Fed controlled the money supply was through the fed funds rate, and that's why they always talk about Volcker raising the fed funds rate to 20%. I suppose my main point of confusion is whether they actually have tangible control on this rate or whether they can only aim for it through tactics.
Aim. And set the rate higher for the discount window.
When Volcker raised rates for the banks, they had to go to the private sector to get cheaper loanable funds. So people started saving more and more at say, 18% return, and put that money in the banks to keep the capitalized.
When the rate is very low, no one wants to save because banks won't pay any interest on savings. It is cheaper for the bank to get all new credit directly from the central bank. Low interest rates cause all sorts of mischief in the short and long term. Rates too high can slow economic growth as well. The market should set the price of money based on supply and demand.
The problem with the central bank moving rates up and down, is that they almost always reflect a political agenda, not a real indication of the amount of savings for capital investment in an economy. An economy which does not save, cannot grow. This is why GDP is a nonsense number. It includes debt, the theory being, if you can borrow, then you are growing, but when you borrow against yourself, it's just an accounting trick.
So basically what you're saying is there's TWO methods for lowering the rate. One is the fed funds rate, and the other is buying their own debt in exchange for reserve credit. I still don't get where they get the money for that, though, if they're already up to their eyeballs in debt.
Because it is a monopoly (legal tender laws), the accounting tricks that are run can persist for decades, because no one can stop participating in the scheme.
That is why Ron Paul agitates for market money, which would undo legal tender laws, and thus give people a chance to escape the erosion of value from inflation.
They create the reserve credits out of thin air, and that credit is created to steal purchasing power from everyone holding dollars in the economy in order to pay for government spending, and bankroll the banks in the global investment casino. The theft occurs by diluting the currency as fractional reserve pyramids those reserves into lots of new money. More money chasing the same number of goods = higher aggregate prices. This is called inflation (price inflation), but it is really only a symptom of inflation (monetary inflation).
It's all fascinating stuff really. Terribly depressing when you first start to grasp how the game is stacked against the average person, but enlightening when you start to plan your investments and business to avoid harm from the system.
