Congress Scrambling to Avoid Government Shutdown

Historically, government shutdowns have not caused a major reaction in the markets. But shutdowns can increase market volatility, and an extended shutdown could have an impact on the overall economy.

Facing a September 30 deadline to avoid a government shutdown, the deeply divided Congress is struggling to find a path to passing a short-term funding measure to keep the government open and operating. A shutdown that begins on October 1 looks increasingly likely.

Government shutdowns have not historically produced significant market reactions. But an extended shutdown could have broader impact on the economy.

Here's what investors need to know.

How did we get here?

Among the most basic responsibilities of Congress is funding federal government operations. Every year, lawmakers are supposed to pass the 12 appropriations bills that fund every government agency and program by September 30, in time for the start of the government's fiscal year on October 1.

But their track record for doing so is terrible. The last time all 12 bills had passed Congress by the deadline was 1997.
