NEW YORK, Sept 22 (Reuters) - U.S. stock index futures rose on Tuesday as the U.S. dollar hit a 1-year low against the euro ahead of the start of a Federal Reserve monetary policy meeting, boosting oil and metals prices.
The Federal Reserve starts its two-day monetary policy meeting on Tuesday with a decision on interest rates due at around 2:15 p.m. (1815 GMT) the following day. Markets will be looking for any comment indicating how the Fed might wind down its financial stimulus measures, given the improving macroeconomic data. For details see [ID:nN21312982].
The euro reached a one-year high against the U.S. dollar as dealers took advantage of the greenback's gains the previous session to resume selling ahead of the Fed meeting and a G20 summit later in the week. The dollar index <.DXY> tumbled 0.8 percent.
"The dollar is under pressure this morning, and that is (increasing) risk appetite in commodities," said Peter Cardillo, chief market economist at Avalon Partners in New York.
He said the shift to commodities "is spilling over into the equity markets as well."
