The financial markets were collapsing with concern for a braking economy, and the Federal Reserve leader tried to assure investors that the central bank was getting modest.
But it could also have been Janet Yellen, who as chair said this early 2016 not long after a controversial December 2015 rate hike left markets unwavering: "I consider it appropriate for the committee to be cautious about adjusting policies … The decline in some indicators has increased the risk of" growth falling. " In that case, the return on inflation of 2 percent may take longer than expected and may require a more accommodating attitude to monetary policy. "

You get the idea In over three decades and four Fed chiefs, there have been half a dozen sharp market downturns driven by a growth hazard, outside of a US recession, in each case easing market pressure on valuation pressure, punctual investor confidence, leading to moderate growth and domestic bonds – and forced the central banks to stop austerity programs or even to ease the policy.
