Goldman Sachs Research previews tomorrow's October FOMC decision.

"Comments from FOMC participants since their last meeting point to a compromise to raise the funds rate every other meeting. This means that the FOMC is set to skip raising rates at its October meeting but is likely to deliver a second hike in December," GS notes.

"We do not expect significant new information from the press conference. The seemingly strong support for hiking every other meeting means there is likely a high bar to deviate from that plan through the end of the year, which should limit the impact of Fed communication for now," GS adds.
