Federal Reserve Bank of Atlanta President Raphael Bostic said recent structural shifts in the economy are likely to lead to larger and more frequent revisions to official U.S. statistics. “With so much in flux, large revisions to data may be more frequent,” he told reporters on Thursday, signaling that policymakers and investors should brace for greater uncertainty in the initial readings of key indicators. Bostic’s remarks come ahead of a busy data calendar next week that includes the Conference Board’s consumer-confidence survey, the Commerce Department’s first revision of second-quarter gross domestic product, and the Federal Reserve’s preferred inflation gauge, the personal consumption expenditures price index. The Atlanta Fed chief suggested that evolving spending patterns and business models are complicating the work of government statisticians, increasing the odds that preliminary figures will be substantially adjusted in subsequent releases.
