[By NBC-1TV H. J Yook]Bernanke‘s readiness to do more (today or next month) and Draghi’s bond-purchase plan is not only a game-changer, but a sharp blow to “tail risk” and is an added boost to supporting market confidence.

There is as much as 60% chance of QE3 being announced at today‘s FOMC decision (12.30pm ET, 5.30pm BST). Bernanke’s conference follows at 2.15pm ET (7.15pm BST).

Although we do not expect QE3 to be started today (US data and markets do not yet merit immediate stimulus), one argument favouring QE3 today is that Bernanke will use the scheduled press conference to explain the new program, rather than waiting for the October meeting, which has no schedule press conference, and therefore no opportunity to explain any new announcement apart from the statement.

Any QE3 announced today is expected to take the form of purchasing US Treasuries and Agency Mortgage Backed Securities (MBS). It is not clear whether the Fed would specify any amount, and instead may announce an-open ended program.

Watch the third paragraph of the FOMC statement (known as the forward guidance), focusing on the guidance phrase in the final sentence, is likely to be changed from the current sentence: “... warrant exceptionally low levels for the federal funds rate at least through late 2014,” to: “... warrant exceptionally low rates at least 2015.” Such an extension would likely serve as an offset for any disappointment from no QE3 today and will underline the readiness for the Fed to do more if conditions required them.
