Stocks tumble on Powell's balance sheet comments and as trade hopes fade

U.S. stocks fell Tuesday as expectations faded that this week's trade talks would produce a deal and after Fed Chairman Jerome Powell said the central bank will "soon" start increasing the size of its balance sheet.

Powell, in a question and answer session, said policymakers will "soon announce measures to add to the supply of reserves over time." The Fed amassed a $4.5 trillion balance sheet in the aftermath of the Great Financial Crisis, and in an effort to normalize policy began reducing its size in June 2017.

His remarks followed more downbeat news on trade talks between the U.S.-China, including word that Chinese Vice Premier Liu He, who is leading the delegation, has not been designated as a special envoy, meaning he cannot make any decisions and must report to President XI Jinping. Deputy-level talks began Tuesday in Washington, and higher-level talks are set to start on Thursday.

All three of the major U.S. indexes finished at session lows, with the Dow Jones Industrial Average down 313 points, or over 1 percent.
