Futures down: Dow 0.27%, S&P 500 0.28%, Nasdaq 0.29%

April 11 (Reuters) - U.S. stock index futures fell on

Friday after China increased its tariffs on U.S. imports to

125%, escalating a trade war that could disrupt global trade and

trigger an economic downturn.

China's move comes after U.S. President Donald Trump on

Thursday ramped up pressure on the country by lifting tariffs to

145%, even as he announced a 90-day tariff reprieve on most

trading partners.

Stocks have been on a roller-coaster ride in response to

tariff announcements in the past few days. Wall Street fell for

four straight sessions, before bouncing back on Wednesday with

the S&P 500 seeing its largest one-day percentage jump

since October 2008.

Stocks, however, slumped again on Thursday and were more

than 7% off from levels seen before last week, when Trump's

"reciprocal" tariffs sparked the market rout.

Amid the volatility, all three indexes are set for robust

weekly gains, with the Nasdaq set for its best weekly showing of

the year so far.

At 04:32 a.m. ET, Dow E-minis were down 108 points,

or 0.27%, S&P 500 E-minis were down 14.75 points, or

0.28% and Nasdaq 100 E-minis were down 54 points, or

0.29%.

Most megacap and growth stocks ticked lower in premarket

trading, though Tesla lagged with a 1.9% fall.

Later in the day, U.S. quarterly earnings season will pick

up pace with big banks such as JPMorgan Chase & Co ( JPM ),

Morgan Stanley ( MS ), Wells Fargo & Co ( WFC ) and asset

manager BlackRock ( BLK ) scheduled to report before markets

open.
