U.S. industrial production, boosted by heavy demand for electricity during the summer heat wave, climbed 0.4% in June, the ninth consecutive month without a decline, the Federal Reserve reported. The Fed said the June advance followed identical gains of 0.5% in both April and May and left output 5.8% higher than it was a year ago. Analysts said the continued improvement showed that American manufacturers were still benefiting from an export boom, which has helped push the nation’s jobless rate down to a 14-year low of 5.3% while giving the country the smallest trade deficits it has seen in almost three years.
