WASHINGTON — American industry boosted production in April and kept running at the highest rate in nearly five years, the Federal Reserve Board said yesterday in a report viewed as a solid sign of economic strength.
On the eve of what could be an important decision on interest rates, the Fed said industrial production rose 0.3 percent last month, following a 0.5 percent gain in March. Monthly output has now risen in an unbroken chain that started in June. The overall increase for April was tempered, however, by a decline in automotive production.
