"I think it could come in hot," said Grant Thornton chief economist Diane Swonk. "It looks like we could get more broad-based inflation. There is supply shock there. You start getting spillover of energy prices and other things."

Bank earnings kick off on Wednesday with JPMorgan reporting before the bell. Last quarter, the bank beat on the top and bottom lines, boosted by better-than-expected loan losses. The Street expects third-quarter earnings per share to jump just 2% from the year-ago period.

JPMorgan has traded lower the day of its last four earnings reports, despite beating on the top and bottom lines each time, according to Bespoke Investing group.

Delta Air Lines also reports before the opening bell on Wednesday. Analysts are expecting to see positive earnings per share, after six straight quarters of per-share losses.

"This clearly represents the first quarter of real EPS risk that investors have had to deal with in the COVID recovery, as GDP estimates have collapsed since mid-August on nothing short of historic supply chain issues," said Tavis McCourt, institutional equity strategist at Raymond James. "However, consensus EPS at the index level has not changed meaningfully, as, remarkably, a greater number of stocks have seen positive earnings revisions since mid-August than negative."

Apple shares were slightly lower in premarket trading after a Bloomberg News report that it is likely to cut iPhone 13 production because of chip shortages. Chipmakers including Skyworks and Broadcom were also lower in premarket trading.

The Federal Open Market Committee will release the minutes from its September meeting at 2 p.m. on Wednesday. Investors will be looking for clues about timelines surrounding the central bank's planned taper for its bond-buying program.
