"The market's going to be sanguine about this because [politicians have] found a way to solve this in the past," said Tim Hopper, chief economist at TIAA-CREF. "We're approaching this as an event that creates volatility, not a trend that changes market direction. And on the economic realm, this is going to have a small-scale impact to growth."

The White House ordered federal departments to execute shutdown plans, leaving nearly 800,000 people out of work, after Democrats and Republicans failed to agree on a spending bill before Monday's midnight deadline. The Senate twice rejected the House of Representatives' demands to delay portions of the Obamacare health insurance bill. Now, the two parties must strike a deal on raising the federal borrowing limit to avoid a debt default by October 17.

This is the first partial federal shutdown since 1996, and it is uncertain for how long it might last.

President Barack Obama criticized the House of Representatives Tea Party members for shutting down the government over an "ideological crusade" on health- care reform, adding that the longer the shutdown continues, the worse the impact will be.

"History tells us it is not necessarily a bad thing for investors," according to Jeff Kleintop, chief market strategist at LPL Financial. "The 16 government shutdowns over the past 40 years that have ranged from 1 to 21 days have not been particularly negative for stock market investors, averaging only a 2 percent decline for the S&P 500."

"More importantly, from a longer-term perspective they preceded above average returns," he continued. "The S&P 500 Index has risen 11 percent on average in the 12 months following the shutdowns, above the 9 percent for all periods. Notably, in the last government shutdown that took place 17 years ago in late 1995, the S&P 500 rose 21 percent in the following year."

On the economic front, the manufacturing sector expanded at its fastest pace in almost 2-1/2 years in September, according to the Institute for Supply Management (ISM).

Meanwhile, construction spending for August, which had been scheduled for 10 am ET was canceled due to the government shutdown. And the Labor Department's Bureau of Labor Statistics said the nonfarm payrolls report will not be released on Friday.

The Labor Department will still publish its weekly jobless claims reports as usual on Thursday.

Daiwa Capital Markets' Grant Lewis said the negative impact on growth would be directly proportional to the length of the shutdown.

"With the deadline to extend the debt ceiling (17 October) also rapidly approaching, the longer there is no agreement on getting the government back up and running, the greater concerns will be over getting agreement on the debt ceiling, further fueling economic uncertainty," he wrote in a note.
