Wall Street opens lower after BOJ rate decision surprise

The BOJ's decision to hold steady in the face of soft global demand and a rise in the yen was particularly jarring for markets after media reports that the central bank wanted to go deeper into negative interest rates. The BOJ's decision comes a day after the U.S. Federal Reserve decided to hold steady on rates and after fears eased that the Fed would signal a rise in June. While the labor market continues to gain strength, inflation remains below the central bank's 2 percent target.
