Full-year economic growth at 2.2% is "a pretty strong number" that is high enough to raise concerns about persistent inflation and likely require tight monetary policy to hold back the economy, Atlanta Fed President Raphael Bostic said on Friday. "Our economy has remained remarkably resilient," with growth in his view expected to accelerate to 2.4% this year, above what he considers the economy's underlying potential. "What that means is that we have to worry about the implications for prices on a strong economy," given inflation at around 3% is "a long way" from the 2% inflation target, Bostic said at an economic event in Birmingham, Alabama.
