Lock Bias Still On....
Anyone see the changes to THIS?
Consistent with the continued evolution of the program's operation, the
New York Fed will begin in late November to use internal staff on
select days to execute the program's agency MBS purchases. From an
operational perspective, the New York Fed's trading approach will
replicate the one currently employed by the program's trading
investment manager, Wellington, although the New York Fed will be
trading in its own name. From a settlement perspective, the New York
Fed will continue to leverage the middle office settlement support of
Wellington for any trades executed by New York Fed staff. While the New
York Fed plans to continue to employ the services of outside investment
managers, the New York Fed anticipates that, through the balance of the
program, the trading days on which its own staff conducts the program's
purchasing activity will gradually increase relative to those trading
days on which Wellington executes the program's purchasing activity.
ps...am I being clear on my lock/float stance?
