Washington, Sep 9 : US economic growth "downshifted slightly" to a moderate pace in early July through August amid a Delta variant-fuelled Covid-19 resurgence, according to a Federal Reserve survey. "The deceleration in economic activity was largely attributable to a pullback in dining out, travel, and tourism in most Districts, reflecting safety concerns due to the rise of the Delta variant," the Fed said in its latest survey on economic conditions, known as the Beige Book, based on information collected from its 12 regional reserve banks. "The other sectors of the economy where growth slowed or activity declined were those constrained by supply disruptions and labour shortages, as opposed to softening demand," Xinhua news agency quoted the survey released on Wednesday as saying. In particular, weakness in auto sales was widely ascribed to low inventories amidst the ongoing microchip shortage, and restrained home sales activity was attributed to low supply, according to the survey. "Looking ahead, businesses in most Districts remained optimistic about near-term prospects, though there continued to be widespread concern about ongoing supply disruptions and resource shortages," the Fed said. The survey also showed that inflation was reported to be "steady at an elevated pace", as half of the Fed districts characterized the pace of price increases as strong, while half described it as moderate. "Most districts noted substantial escalation in the cost of metals and metal-based products, freight and transportation services, and construction materials." The Fed has pledged to keep its benchmark interest rate unchanged at the record-low level of near zero, while continuing its asset purchase program at least at the current pace of $120 billion per month until "substantial further progress" has been made on employment and inflation. "Assuming the economy continues to improve as I anticipate, it could be appropriate to start reducing the pace of asset purchases this year," Federal Reserve Bank of New York President John Williams said on Wednesday at a virtual event. "I will be carefully assessing the incoming data on the labour market and what it means for the economic outlook, as well as assessing risks such as the effects of the Delta variant," he said. /IANS
