The issue with Basel III is actually very simple.
The Fed issued a godawful amount of $USD which now has to sit in banks, not to trigger inflation or deflation, but in order to stabilize the banks.
The increased reserve requirement is effective in propping up banks, even if the money backing it up is just an illusion.
I'm going to just use hypothetical numbers here instead of the ones that the Fed actually used, but this is how it works.
Let's say banks are doddling along with a 20% reserve requirement, cheerfully lending out five times as much money as they actually hold. And the doctrine is, "you can't suddenly inflate the money supply. That would lead to hyperinflation. Imagine every atom of your body, radiating outward at the speed of light! That would be BAD!
Then something happens (like the financial industry crashing) that makes it utterly clear that 20% is not enough of a reserve requirement. Banks that actually did hold 20% reserves are struggling to keep from going under as 17%, 18%, and 19% of their loans suddenly go into default. It's a crisis of Biblical proportions! And what about this guy over here who caused the crisis? It's true sir, this man has no dick.
Guys at the Fed decide that it's really only safe for bankers to loan out 3 times as much money as they hold, so the reserve requirement ought to be raised from 20% to 33%. But if the banks suddenly have to make it up on their current reserves, then we are all DEAD, because they are struggling to survive by spending down a 20% reserve to meet their obligations. To deal with that you'd have to suddenly and dramatically raise the money supply! And that would be BAD! In order to even get back to 20% within some reasonable time, the bankers are having to raise interest rates on mortgage holders by some obscene amount like going from 8% to 23% on long-term mortgages. If they were trying to get to a 33% target, they'd have to raise their interest rates on mortgage holders to something even more obscene like 50% or 60%, and then we would all be dead. Panic in the streets, rains of blood, dogs and cats living together, -- it's the end times!!
Then someone comes up with a ray of hope in the darkest hour, and says .... hey, Quantitative Easing! The new reserve requirement will turn the financial sector of our economy into a "giant sucking noise" that takes a hell of a lot of money out of the economy, but what if we just give out about that same amount of money? People will spend it once or twice, then it'll wind up getting sucked into the giant black hole we've just created in our banking sector, and if we add the money to the economy at about the same rate that it gets sucked up by the giant black hole, then we can do it without creating (too much of) a liquidity crisis! Why, we might not even have a revolution! But hey, wouldn't that be .... you know, BAD? Well, There's a chance -- a very small chance -- we might survive. Oh, I love this plan! This is a great idea!!
And so the Fed set out to do this thing. They've been adding money to the economy at about the same rate that the banks have been required to suck it out of the economy. Now it's a couple years later, the reserve requirements have been raised and, mostly, met, and the amount of money actually in circulation has stayed roughly the same. The banks are now holding 33% instead of 20%, they've even managed to recover the reserves that they had to spend down in the crisis, if another 20%-threatening crisis occurs they'll be able to withstand it, and the public has been largely unaffected because money has entered the economy through QE just about as fast as it has gotten sucked out of the economy by banks that would otherwise collapse.
It's -- actually not that bad a plan. What it comes down to is that in order to raise the amount held in bank reserves from 20% to 33%, the 'actual' money supply had to increase from 1/5 to 1/3 of the 'circulating' money supply - meaning, from $3 on every circulating $15 to $5 on every circulating $15, so 40% of the 'actual' money supply at the end is 'new' money that didn't exist before. Throw in another 15% or so to allow the banks to recover from the hole they were in with respect to their 20% margin obligations at the start of the crisis, and you have a picture that looks pretty much like the picture today.
Now comes the next and possibly even more difficult trick. Now that the goal of stabilizing banks and raising the reserve requirements so they stay a bit more stable is more or less met? Now they have to ... stop. If they can manage this one last trick, then hats off to them because, well, frankly there's no other way we could have come through that mess starting from where, through ignorance and incompetence, they started. If the new reserve requirement is met, then maintained, and they can judge exactly the right moment to stop printing so goddamn much new money, then we won't have hyperinflation because all that new money will stay in the banks and won't enter circulation.
Thanks for that. Does all of this new money not also come with huge interest obligations? Assuming the "plan" worked flawlessly, how is this new interest to be paid going forward, assuming everything else went back to normal? Wouldn't that require more money, and more debt all on its own? (setting aside the impossible task of tapering).
