The world's most powerful central bank will put out a statement at 1400 hrs Eastern Time, detailing its monetary policy.
Market participants the world over will be tracking the Fed announcement for clues as to the future pace of its asset-buying programme.
The Fed's $85bn (£52.7bn, €61.6bn) a month bond-buying stimulus has supported the US economy and markets the world over for a while now.
Standard Chartered said in a note to clients: "The Federal Open-Market Committee (FOMC) will conclude its two-day meeting today, releasing its statement at 14:00 ET (there is no press conference). The minutes of the September meeting showed that the decision not to taper its USD 85bn/month quantitative easing (QE) programme was a 'relatively close call' for several members. But we think that, given recent soft data and the 16-day government shutdown, the FOMC will be firmly in 'wait-and-see' mode at this meeting, keeping QE unchanged".
"The statement is expected to reflect that QE tapering, although still on the FOMC's horizon, is now off the table in the near term. It is likely to have a more prudent tone, particularly on how recent activity is characterised. It may take note of the recently softer payroll data (the average fell to 143,000/month in Q3, from 182,000 in Q2), and housing activity, as the rise in long-term rates due to tapering fears has taken its toll on the economy. Our main scenario remains QE tapering starting in March 2014", according to Standard Chartered.
Scotiabank said in a note to clients: "One possibility in the FOMC statement that will not be accompanied by forecast revisions or a press conference is that the Fed could strengthen forward rate guidance while leaving its bond purchase program unchanged at $85 billion amid no hints of tapering any time soon. This could include lowering the unemployment rate threshold at which a higher fed funds target rate would be considered".
"With the December 13th deadline for budget negotiations, the extension of funding for the US government until January 15th and the suspension of the debt ceiling until February 7th, the Fed will continue to caution on fiscal policy risks and may signal near-term growth downsides as a direct consequence of the government shutdown and the likely related confidence shock", according to Scotiabank.
"No sooner will the ink be dry on the statement than three Fed speakers will take to the stage on Friday. They include St. Louis Fed President James Bullard (voting 2013, nonvoting 2014), Minneapolis Fed President Narayana Kocherlakota (alternate 2013, voting 2014) and Richmond Fed President Jeffrey Lacker (nonvoting 2013, alternate 2014)", the Canadian bank added.
Meanwhile, data from Germany showed that the country's unemployment rate remained unchanged at 6.9%.
