* Futures up: Dow 156 pts, S&P 10.25 pts, Nasdaq 19 pts
Feb 26 (Reuters) - U.S. index futures pointed to a strong start for Wall Street on Monday, buoyed by gains for stock markets worldwide and the belief that new Fed chair Jerome Powell will keep the U.S. central bank on a steady course of monetary tightening.
Powell faces questions from both houses of the U.S. Congress in semi-annual testimony starting on Tuesday, his first major set piece since he took over at the start of February.
Traders have worried that Powell's appointment could make the Fed less ready to soften its policy line when markets sound the alarm - as they did in a selloff earlier this month due to a rise in U.S. government bond yields.
Powell has said little about the selloff, besides saying at his swearing-in ceremony last week that "we will remain alert to any developing risks to financial stability."
The Fed said on Friday it expected economic growth to remain steady and saw no serious risks on the horizon that might pause its planned pace of rate hikes.
The week is heavy on data, with a report on personal consumption expenditure, the Fed's favorite gauge of inflation, expected on Thursday.
