The US Federal Reserve is the leader among all central banks, but they are humble enough to learn from the youngest central bank of the world. That is press conference. Originally, the Federal Reserve had no press conference after the FOMC meeting, but since the European Central Bank (ECB) established, they have press conference after rate decision, so that the press can ask the president a lot of question that the market concern most. For in the era of Greenspan, once after the statement of rate decision announced the market had great turmoil that at length the Fed had to announce a supplement to clarify the points a few hour later in order to keep the market stable.
On April 20, 2011, the chair Ben Bernanke had a breakthrough and held the first press conference immediately after the FOMC meeting. Just made clear their standpoint and no need to guess. But it was not a routine one. Just a testing and have to see the response.
After that, press conference were held every 2 meetings, including a summary of economic projection that is announced 4 times a year. That is from 2011 to 2018.
Jeromy Powell revealed another change during the June 2018 press conference, stating that starting in Jan 2019, and every scheduled FOMC meeting would be followed by a press conference. The goal was to foster a more open dialogue and improve public understanding of Fed actions, and the Economic projection remains the same announcing 4 times a year.
They are bumble enough and do not had any arrogance and is willing to learn from the youngest central bank of the world which is ECB.
Well done!
