KEY POINTS
  • Strategists said the renewed sell-off in U.S. markets on Monday is in part thanks to partisan gridlock in Congress over the debt ceiling and government shutdown.
  • House Speaker Nancy Pelosi, D-Calif., said Monday that the House will this week pass a government funding bill and a debt ceiling suspension.
  • The bigger hurdle is likely the Senate, where lawmakers will need to muster 60 votes to pass such a bill that isn't tied to the separate reconciliation legislation.
  • "The framework of Washington policy is shifting to more risk after 18 months of unlimited fiscal and monetary policy," wrote Dan Clifton, head of policy research at Strategas.

As the Dow Jones Industrial Average fell 614 points on Monday — its worst day since July — and the S&P 500 shedding 1.7%, strategists say gridlock on Capitol Hill is starting to send shutters through the market.
