(Bloomberg) -- Several Federal Reserve presidents argued Thursday that surging Treasury yields reflect economic optimism for a solid recovery from the Covid-19 crisis and stressed that the central bank has no plans to tighten policy prematurely.“I think the rise in yields is probably a good sign so far because it does reflect better outlook for U.S. economic growth and inflation expectations which are closer to the committee’s inflation target,” St. Louis Fed President James Bullard told reporters after a virtual speech.Comments by Bullard and two other Fed leaders, Atlanta’s Raphael Bostic and Kansas City’s Esther George, showed that the central bank’s policy makers are solidly united behind Fed Chair Jerome Powell’s patience in making any adjustments to monetary policy.Powell told lawmakers this week that the nation was still a “long way” from the Fed’s goals for full employment and price stability, signaling the central bank will maintain ultra-easy monetary policy for some time -- despite hopes for a strong economy later this year as vaccinations spread.The Fed presidents agreed with Powell’s characterization of the rise in yields as “a statement of confidence” in the economic outlook. The 10-year Treasury yield reached 1.61% Thursday, the highest in more than a year, before trimming its gains.“Much of this increase likely reflects growing optimism in the strength of the recovery and could be viewed as an encouraging sign of increasing growth expectations,” George said in a speech.Bostic told reporters he was not expecting the Fed to respond to rising yields: “Yields have definitely moved at the longer end, but right now I am not worried about that.”All three Fed presidents said it was premature to begin discussing tapering of the central bank’s massive bond-buying program, with Bullard noting that Powell would initiate the discussion when it’s appropriate.Strong ReboundIn separate remarks, a fourth Fed leader, New York’s John Williams, said the economy was poised for a strong rebound. “Indeed, with strong federal fiscal support and continued progress on vaccination, GDP growth this year could be the strongest we’ve seen in decades,” he said, though he added that underlying inflation is likely to remain “subdued for some time.”Bullard echoed that optimism, noting the Atlanta Fed’s tracking model shows robust growth for gross domestic product in the first quarter. He predicted the U.S. unemployment rate will drop to 4.5% by year’s end, with pent-up demand and elevated savings boosting spending by Americans.“I gave a rosy outlook today but it’s only an outlook,” Bullard said. As for a policy change, “the chair has wanted to start that conversation only when it’s appropriate and not get ahead of ourselves even though we do have high hopes the pandemic will come to an end.”Bostic emphasized that the labor market still has considerable pain, especially for lower-income workers and minorities, and that it would take a long time to regain the 10 million jobs that have been lost.“Just to remind you, our mandate is full employment,” Bostic said Thursday during a virtual speech to the Atlanta Fed’s banking-outlook conference. “It’s not full GDP. It is not the size of GDP. So this disparity is something that is important and something we are going to have to continue to watch closely.”(Updates with comments by New York Fed president in ninth paragraph.)For more articles like this, please visit us at bloomberg.comSubscribe now to stay ahead with the most trusted business news source.©2021 Bloomberg L.P.
