NEW YORK, Sept 18 — US stock index futures dipped today as investors waited for the Federal Reserve’s decision on interest rates in what has been a rocky week for global markets.

The central bank is expected to lower interest rates by a quarter percentage point for the second time in three months, but a deep divide among policymakers has seen traders abandon all bets on a third reduction this year.

At 7:00 a.m. ET, Dow e-minis were down 18 points, or 0.07 per cent. S&P 500 e-minis were down 3.25 points, or 0.11 per cent and Nasdaq 100 e-minis were down 9.25 points, or 0.12 per cent.
