Wall Street has seen jittery trading so far this week as investors opt to sit on the sidelines until the kickoff to the Fed's annual Monetary Policy Symposium in Jackson Hole, Wyo., on Thursday.
"One issue that is likely to garner considerable attention during the symposium is the outlook for the neutral fed funds rate," Deutsche Bank analysts wrote in a note. "Having fallen to -- and remaining persistently near -- record low levels, the neutral rate has drawn intensifying scrutiny from key Fed officials. Its outlook has pivotal implications for both the likely future path of the fed funds rate and the way in which monetary policy is conducted in the future."
Yellen will cap off the week with a speech at the summit which will provide important context to the markets' outlook for rates. Yellen's comments will likely remain dovish and conservative, pushing data dependency for any future rate moves.
The chances of a September rate hike currently sit at 18%, according to CME Group fed funds futures. A rate hike in November has better chances at 41%.
