March 16 (Reuters) - U.S. stock index futures were up on Monday, putting the benchmark S&P 500 on track for a rebound after three weeks of losses, as currency markets helped reassure U.S. investors concerned about how a strong dollar would hurt earnings.

Investors have been cautious ahead of a U.S. Federal Reserve statement due on Wednesday, when they expect the central bank to give a clearer signal on the timing of its first interest rate hike in almost a decade.
A recovery in the euro was reassuring investors as a rapidly rising U.S. dollar would put even more pressure on U.S. corporate earnings, said Nick Colas, chief market strategist at brokerage Convergex, in New York.

Along with signals for a rate hike timing, investors will be anxious to hear what Fed Chair Janet Yellen has to say about the strong dollar on Wednesday, Colas said.
