Futures up: Dow 0.18%, S&P 500 0.14%, Nasdaq 0.13%

July 9 (Reuters) - U.S. stock index futures edged up on

Wednesday, as investors navigated the currents of President

Donald Trump's aggressive tariff moves and kept a close watch on

negotiations with global trade partners.

By 5:28 a.m. ET, U.S. S&P 500 E-minis were up 8.5

points, or 0.14%, Nasdaq 100 E-minis were higher 29

points, or 0.13%, Dow E-minis were up 78 points, or

0.18%.

Trump said on Tuesday he would impose a 50% tariff on

imported copper and soon introduce long-threatened levies on

semiconductors and pharmaceuticals, a day after he pressured 14

trading partners with fresh tariff letters. He said "a minimum

of seven" tariff notices would be released on Wednesday.

After Monday's sharp sell-off, sparked by the White House's

sweeping new tariff threats against major trading partners like

Japan and South Korea, Wall Street's reaction remained

relatively muted.

The S&P 500 and the tech-heavy Nasdaq both

closed little changed on Tuesday, a stark contrast to the wild

volatility following Trump's "Liberation Day" tariff

announcement in April.

With the deadline for tariffs now moved to August 1,

investors are pinning their hopes on negotiations to stave off

an all-out trade war.

"Market volatility is likely to pick up, but the latest

development does not constitute an escalation in the trade war,"

UBS analysts said.

Last week, the S&P 500 and the Nasdaq closed at record highs

following a surprisingly strong jobs report that pointed to

resilience in the labor market. Now, markets await Thursday's

initial jobless claims figures for further insights into the

labor market.

Traders will also parse through the minutes from the Federal

Reserve's June meeting, due at 2:00 p.m. ET, for any hints about

when policymakers might resume easing rates.

While a July rate reduction is almost fully ruled out, the

odds of a September cut stand at about 63%, according to CME

Group's FedWatch tool.

Amid Trump's chaotic tariff policies, the Fed has refrained

from cutting interest rates, wary of how trade uncertainty could

impact growth and inflation.
