The Federal Reserve raised interest rates again today. The Fed funds rate inched higher by 25 basis points to 3.0%, only just below inflation’s pace, measured by the consumer price index, which advanced by 3.1% for the year through March. Twelve months previous, CPI was rising by 1.7% and the Fed funds rate was 1.0%. In short, the real (inflation-adjusted) Fed funds rate is close to being neutral, as opposed to negative, for the first time since 2002.
