Tommaso, I understand the basics of money creation which you summarized so well in your post, but perhaps don't always think them through clearly. As far as the stock market boom stimulating an increase in the money supply, that was pretty speculative. But if you include money market funds in money, what are the effective reserve requirements for them? That's really what I'm asking, I guess. And if these are not reserve requirements set by law, but, perhaps within broad guidelines, as a matter of discretion in the contracts creating the short-term obligations which are held as assets by a money market fund, then I would imagine a shift towards brokerage money market funds could change the multiplier for that type of money, depending whose assets the brokerage holds (is it primarily their *own* short term obligations, for instance?!!).
So, the nub of the question is the nature of "reserve-like" requirements, if any, for money market mutual funds. I.e., just what, asks this financial semi-ignoramus, are the assets I hold in my so-called brokerage money market account? Wait, it's FDIC-insured, so there are reserve requirements for that at least... phew...-g-
Another, more dangerous, way in which the stock market boom might lead to increases in the money supply is through money demand. This is sort of a version of the "great enabler" thesis, perhaps... The stock market boom has greatly increased the volume of financial transactions, in which some money is involved, perhaps shifting the demand curve for money and requiring the Fed to accomodate this shift with an increase in the money stock to keep target interest rates stable. This increase in the money stock is "Greenspan enabling financial asset inflation". Note that the cost of *not* enabling financial inflation by a market that wants to inflate, though, is to tolerate higher interest rates, possibly bringing on a recession. I'm sure Greenspan wants to be saddled with *that* -g-.
And thanks much for the .pdf link, also!
