Oil prices climbed with worries about the possible spillover effects of violence in the Middle East.
The stock market was less fearful, though, and flipped from modest morning losses following potentially encouraging news on interest rates, which have been dragging Wall Street mainly lower since the summer.
The S&P 500 rose 0.6%. The Dow rose 197 points, and the Nasdaq composite added 0.4%. They perked higher after two officials at the Federal Reserve suggested they may not need to raise interest rates again at their next meeting at the end of this month.
