Oil prices got back to jumping, while sinking technology stocks dragged Wall Street lower amid uncertainty about what the Federal Reserve will do to get high inflation under control. The S&P 500 fell 1.5% Wednesday after briefly erasing all of an earlier drop of 1.2%. The Dow Jones Industrial Average tumbled 2.2%, and the Nasdaq composite sank 1.7%. The price of Brent oil leaped back above $88 per barrel to add further pressure on inflation. The Fed pledged again to get inflation back down to 2%, but it offered few clues on how it would do so after holding interest rates steady.
