With the bogey of a minimum QE announcement of $100 billion a month, leading to an in kind purchase of Treasurys, in addition to $30 billion a month from MBS Refis courtesy of QE Lite, a very likely announcement during next week's FOMC meeting, that nobody is talking about, is that the Fed may raise the existing 35% SOMA limit, or abolish it altogether, due to the imminent ceiling hit of purchasable CUSIPs. As a result, as Morgan Stanley suggests, possibly the most profitable Fed frontrunning trade if one wishes to bet on consensus QE, is to buy SOMA excluded CUSIPs as these will be telegraphed to be next in line to be monetized. Of course, in the apocryphal scenario that the Fed disappoints the market and decides to announce a less than $100 billion a month, or, gasp, nothing at all, MS' Igor Cashyn expects a complete bloodbath in rates (and most certainly in risk assets). Then again, the probability of the Fed doing the right and/or prudent thing ever is nil, so we would focus on buying out of favor SOMA issues, because as Morgan Stanley reports: "Net, we like buying what the Fed is buying."And how could one not: after all Morgan Stanley announces that in 2011 net Treasury issuance net of Fed Purchases will be zero!
