June 5 (Reuters) - U.S. stock index futures pared gains on Wednesday after data showed that the private sector in May added fewest jobs since 2010, but expectations that the central bank would cut interest rates to counter any economic slowdown supported sentiment.
Private-sector jobs rose by 27,000 last month, much below expectations of a 180,000 increase, according to the ADP National Employment Report, raising bets that the Fed would cut rates as soon as this month.
Fed Chairman Jerome Powell said on Tuesday the central bank would respond "as appropriate" to risks posed by a global trade war, helping the three main indexes rack up their biggest one-day gains in five months.
"There is nothing to suggest that the Fed is going to cut rates anytime soon, but obviously that could change if we see a little more pronounced slowdown in the short term," said Scott Brown, chief economist at Raymond James in St. Petersburg, Florida.
"The ADP number does raise some concerns about the further impact of tariffs. It adds to the case of interest rate cuts, the odds of that happening are going up."
The focus now shifts to the more comprehensive nonfarm payrolls from the Labor Department due on Friday.
On the trade front, Mexico will begin talks with the United States on Wednesday where officials will seek to persuade the White House that they have done enough to curb immigration and avoid looming tariffs.
President Donald Trump has said he would likely go ahead with new tariffs on Mexican imports next week, despite some opposition from his own party.
