Annual inflation slowed and wage growth remained weak in March, in two datapoints that will reassure Federal Reserve officials that their decision not to raise interest rates was warranted, but are also signs of weakness in the economy.

The Bureau of Economic Analysis reported Friday morning that prices were up 0.1 percent in March, according to its Personal Consumption Expenditures Index, the inflation index favored by the Fed. That pushed the annual rate of inflation down from 1 percent to 0.8 percent.
