Gold slipped in early Asian trade on Thursday as market participants looked ahead to next week's Federal Reserve policy meeting for guidance on the trajectory of interest rates.

Spot gold fell 0.6% to $4,115.50 per ounce by 0040 GMT, after hitting its lowest since October 15 at $4,104.33 on Wednesday. US gold futures for December delivery dropped 0.4% to $4,132.30.

Traders see just a 16% chance of a rate hike next week but are pricing in a 90% likelihood of an increase in December, according to CME's FedWatch Tool.
