Quote of the Day: Tobin’s Bathtub Economics

when it comes to interest rates, Tobin did not teach economics; he lectured about monetary plumbing. Under bathtub economics, the Federal funds rate is a dumb plumbing control—-the pavlovian lever you pull when you want more aggregate demand. But here’s a news flash.  Its actually the smartest thing in the financial firmament—that is, its the price of hot money. 

Indeed, its the most important single price in all of capitalism because it regulates the protean and  combustible force of speculation—that is, the deeply embedded human instinct to chase something for nothing if given half the chance. Accordingly, the very last lever the Fed should toy with is the price of money;  and the very last economic precinct it should try to “stimulate” is the money markets of Wall Street. That’s where the demons and furies of short-run, lightening fast financial speculation lurk, work and mount their momentum trading campaigns—ripping, dipping and re-ripping as they go.

Stated differently, the Federal funds rate is the price of trading risk—the regulator that drives the carry trades. It is the mechanism by which credit is expanded in the Wall Street gambling channel through the process of re-hypothecation.  When the funds rate is ultra low for ultra long it massively expands the carry trades. That is, any financial asset with a yield or short-run appreciation potential gets leveraged one way or another through repo, options or structured trades—- because re-hypothecation produces a large profit spread from a tiny sliver of equity.

Needless to say, the massive carry trades minted in the Fed’s Wall Street gambling channel are a deep and dangerous deformation of capitalism. In money markets that are not pegged by the central banking branch of the state, outbreaks of fevered speculation drive short-term market rates skyward in order to induce more true savings from the market or choke off demand for funds. The money market rate is therefore the economic cop which keeps the casino in check.

Accordingly, the carry trade profit spread can go from positive to negative quickly and drastically, meaning that there are always two-way markets in the underlying financial assets. There is no shooting fish in a barrel full of free money. There are no hedge fund hotels where carry-traders can drive in-the-money strike prices higher and higher because premiums are dirt cheap.

Needless to say, the Fed’s 30-year encampment in the heart of the money markets has destroyed them; it has turned price discovery into the primitive, computerized act of red-green-and-orange-lining the Fed’s latest meeting statement to see which word, tense or adjective has changed.

At the end of the day, the Fed has been implanted in the money markets for so long that it does not even recognize it own handiwork. The speculative disorders and financial bubbles which are the inherent results of its interest rate pegging are seen as exogenous forces which emanate from almost any place on the planet except the Eccles Building. And even if some ultimate responsibility is acknowledged as to errors inside the great house of monetary central planning it’s always put off to failures on its regulatory and supervisory desks, and always after the fact.

This is from David Stockman’s appraisal of Fed Chair Janet Yellen’s latest speech at his Contra Corner.

Oh mind you, this observation applies not only to the US FED but also to contemporary central banking, including the Philippine BSP, where the latter believes blowing bubbles uplifts ‘aggregate demand’ with a cavalcade of 9 months 30+% money supply growth!
