When Will The Fed Start Quantitative Tightening?

Remember all the hullabaloo back in September about the Federal Reserve's decision to shrink their balance sheet? Believe it or not, it was somewhat of a big deal and many strategists were warning about the lack of support for risk markets from this action.Here is the actual announcement from the FOMC's press release: Effective in October 2017, the Committee directs the Desk to roll over at auction the amount of principal payments from the Federal Reserve's holdings of Treasury securities maturing during each calendar month that exceeds $6 billion, and to reinvest in agency mortgage-backed securities the amount of principal payments from the Federal Reserve's holdings of agency debt and agency mortgage-backed securities received during each calendar month that exceeds $4 billion.
