from Zero Hedge:
While endless jawboning and threats of more free (and even paid for those close to the discount window) money can do miracles for markets, if only for a day or two, by spooking every new incremental layer of shorts into covering, there is one problem with this strategy: the “flow” pathway is about to run out of purchasing power. Recall that Goldman finally admitted that when it comes to monetary policy, it really is all about the flow, just as we have been claiming for years. What does this mean – simple: the Fed needs to constantly infuse the financial system with new, unsterilized reserves in order to provide bank traders with the dry powder needed to ramp risk higher. Logically, this makes intuitive sense: if talking the market up was all that was needed, Ben would simply say he would like to see the Dow at 36,000 and leave it at that. That’s great, but unless the Fed is the one doing the actual buying, those who wish to take advantage of the Fed’s jawboning need to have access to reserves, which via Shadow banking conduits, i.e., repos, can be converted to fungible cash, which can then be used to ramp up ES, SPY and other risk aggregates (just like JPM was doing by selling IG9 and becoming the market in that axe). As it turns out, today we may have just hit the limit on how much banks can do without an actual injection of new reserves by the Fed. Read: a new unsterilized QE program.
