Global stock markets and U.S. futures were in the red Wednesday amid new talk that the Federal Reserve may soon begin easing its stimulus measures.
U.S. stock futures were roughly 0.5% weaker ahead of the open, with negative market sentiment blamed on hawkish statements from Chicago Fed president Charles Evans and Atlanta Fed president Dennis Lockhart.
"Both indicated the Fed could initiate tapering [to its bond-buying program] as early as September," said Ishaq Siddiqi, a market strategist at ETX Capital in London.
The prospect of the Fed cutting back on its massive quantitative easing campaign, which has helped push U.S. stocks to record highs, had investors feeling "uneasy," Siddiqi said.
The move downward gathered pace Tuesday as U.S. stocks finished lower, with the Dow Jones industrial average experiencing its largest point and percentage drop since June. Asian markets took up the trend Wednesday -- Japan's Nikkei index declined by 4% as the yen continued to strengthen. The main indexes in China also dropped.
Despite the move lower, U.S. stocks have still gained 18% to 21% so far this year.
