Sept 19 (Reuters) - U.S. stocks index futures pointed to another record open for the S&P and the Dow on Tuesday, ahead of the two-day Federal Reserve meeting that is expected to roll out a plan to pare the central bank's bond holdings.
Investors do not expect the central bank to increase interest rate in the meeting but will closely watch Fed Chair Janet Yellen's views on inflation, which remains stuck below the Fed's 2-percent target rate.
"If I'd be watching anything, it would be primarily with regard to their plans to raise rates in December, which now the market has a 50-50 odds on," said Randy Frederick, vice president of trading and derivatives for Charles Schwab in Austin, Texas.
However, the biggest determinant (a Dec. rate hike) will be how the equity and bond markets react to the reduction of Fed's bond portfolio, said Frederick.
Any reduction in the balance sheet could make it harder for banks and investors to borrow certain Treasuries in the repurchase agreement market, making it more difficult and expensive to bet on or protect against interest rate increases.
