U.S. Federal Reserve on Wednesday lowered interest rates for the first time since the 2008 global financial crisis, amid rising concerns over trade tensions, a slowing global economy and muted inflation pressures. The Federal Open Market Committee, the Fed's rate-setting body, trimmed the target for the federal funds rate by 25 basis points to a range of 2 percent to 2.25 percent after concluding its two-day policy meeting, in line with market expectation.
