Investors continued to weigh in on Federal Reserve Chairman Powell’s remarks at the Cato Institute’s 40th Annual Monetary Conference in Washington on Thursday. “The Fed has, and accepts, responsibility for price stability,” Powell said, reaffirming the US central bank’s commitment to taming inflation. “We must act now – directly, forcefully.” Wall Street expects with increasing confidence that Fed officials will deliver a third straight rate hike of 0.75% later this month, with an institutional jitter raising expectations for the size of the Fed’s benchmark rate hikes.
