All the histrionics over the next Fed chairman, pardon chairwoman, choice are over. WSJ reports that Obama is set to announce Mr., pardon Mrs Janet Yellen as Bernanke's replacement tomorrow at 3 pm at the White House. "The nomination would conclude a long and unusually public debate about Mr. Obama's choice which started last June when he said that Ben Bernanke wouldn't be staying in the post after his term ends in January. Mr. Obama gave serious consideration to his former economic adviser, Lawrence Summers, who pulled out in September after facing resistance from Democrats in the Senate." However, while a Yellen announcement, largely priced in, in a normal environment would have been good for at least 10-20 S&P points, with the debt ceiling showdown the far more immediate concern, the choice of the Chairwoman may not be the buying catalyst that it would have otherwise been.
