Quote from Martinghoul:
Right, so you make a few points here...
Firstly, you agree that the investor in question makes a certain decision. The criteria, if I understand you correctly, is that a) the asset has to be liquid; and either b) the asset has to offer an attractive return in an inflationary environment; or c) in the special case of bonds (which offer sh1t returns in an inflationary environment), it's gotta be bonds that the Fed's purchasing. Now, from what I can see, the Fed can affect the investor's decision inputs only in the c) case. For a), it's unclear to me what the Fed has to do with forcing an investor towards a certain place in the liqudity spectrum. For b), nobody, not even the Fed, knows with certainty whether the future holds inflation or deflation, so this criterion is based on a forecast, which may or may turn out to be correct. You could make an indirect argument about inflation expectations, I suppose, but it's gonna be quite roundabout and tenuous, in a variety of ways. So, apart from bonds, where I see a direct incentive, I don't see how you can argue that the Fed is forcing investors into particular assets.
Secondly, I don't understand what the whole dollar thing has to do with it? Are you now arguing that the value of these assets is going up not because investors are allocating capital into them, but rather because USD is falling? Or is it both? I also have no idea what "dollar is the perfect carry" means. If you buy EM/higher yielding ccies, surely you must mean that USD is the funding ccy and offers, relatively speaking, very poor carry? As to the EM assets, I think that belongs in the previous paragraph.
Now, the most interesting part of your argument is the suggestion that all these investors aren't the households, corps, etc, but rather banks, esp the primary dealers. Lemme ask you a question... What sort of evidence would be required for me to be able to disabuse you of this funny notion? If I offer you some hard numbers, are you willing to change your mind?
As to your last passage, it's very nebulous and I don't like it. We're discussing the specific features of this "environment" that the Fed creates and the "speculative orgy" that ensues. Why don't we keep doing that, rather than discuss general vague concepts and labels?
