June 6 (Reuters) - U.S. stock index futures gave back most
of their gains on Thursday after President Donald Trump said he
would decide on more China tariffs "probably right after the
G20," stoking fears of a further escalation in trade tensions.
The comments follow Trump's threat overnight to hit China
with tariffs on "at least" another $300 billion worth of Chinese
goods. "It feels like an escalation of tension and may be an
elongated trade war and we might have to recalibrate lower,"
said Art Hogan, chief market strategist at National Securities
in New York.
"We're up significantly in two days, at that place it
doesn't take much to roll markets over."
Adding to the concerns, the European Central Bank marginally
cut its growth forecasts for the next two years, acknowledging
the risk that Europe's slowdown will be longer and deeper than
expected.
ECB President Mario Draghi said risks to region remain
tilted to the downside, citing geopolitical uncertainty, the
rising threat of protectionism and vulnerabilities in emerging
markets.
At 8:55 a.m. ET, Dow e-minis 1YMc1 were up 22 points, or
0.09%. S&P 500 e-minis ESc1 were up 2 points, or 0.07% and
Nasdaq 100 e-minis NQc1 were up 1.5 points, or 0.02%.
After a surprise flare up in the trade spat that whipsawed
markets in May, Wall Street's main indexes are on pace for their
first weekly gain in at least a month after top Federal Reserve
officials, including Chairman Jerome Powell, hinted at a rate
cut.
