Dec 17 (Reuters) - Gulf equities ended lower on Wednesday as investors stayed cautious ahead of more U.S. economic signals that could clarify the Federal Reserve's policy outlook, after a closely watched jobs report delivered a mixed picture of the labour market.

Markets are awaiting comments later in the day from several influential Fed officials, as well as U.S. consumer price inflation data for November due on Thursday, which could further shape expectations for the timing and pace of interest-rate moves.

Gulf markets tend to track shifts in U.S. monetary policy expectations as most regional currencies are pegged to the dollar.

"The mood was tempered by upcoming Federal Reserve members' speeches today and crucial inflation data tomorrow, which continued to weigh on regional sentiment," said Milad Azar, market analyst at XTB MENA.

"Markets remain underpinned by solid fundamentals that could support the upward trend once global headwinds diminish and sentiment improves."
