The U.S. Federal Reserve on Wednesday signaled years of extraordinary support for an economy facing a torturous slog back from the coronavirus pandemic, with policymakers projecting a 6.5 percent decline in gross domestic product this year and a 9.3 percent unemployment rate at year's end.

In the first economic projections of the pandemic era, U.S. central bank policymakers put into numbers what has been an emerging narrative: that the shutdowns, restrictions and other measures used to battle a health crisis will echo through the economy for years to come rather than be quickly reversed as commerce reopens.

Some 20 million or more people have been thrown out of work since February, and Fed Chair Jerome Powell acknowledged it could take years for them to all reacquire jobs – an economic blow that is falling heaviest on minority communities at a time when mass protests over police brutality have thrown a new spotlight on racial inequality in the United States.

Powell, acknowledging the nationwide demonstrations in his opening remarks at a news briefing, said it was now the Fed's single-minded mission to bring the job market back to where it was at the end of last year, with the unemployment rate at a record low 3.5 percent and wage gains accumulating for some of the very same lower-paid workers in the service sector that have suffered most during the recent collapse.

"Twenty-two, 24 million people - somehow as a country we have to get them back to work," Powell said via video link after the end of the Fed's latest two-day policy meeting. "They did not do anything wrong. This was a natural disaster."

"It is a long road. It is going to take some time," he said. "We can use our tools to support the labor market and the economy and we can use them until we fully recover."

Years-long fight

The fresh policymaker projections start to show just how long that might take. At the median, officials see the unemployment rate falling to 6.5 percent at the end of 2021 and 5.5 percent at the end of 2022 – still a full 2 percentage points above where it was at the end of last year, representing millions of lost years of work and wages.

"The ongoing public health crisis will weigh heavily on economic activity, employment and inflation in the near term and poses considerable risks to the economic outlook over the medium term," the Fed said in its policy statement.

The response has been an unparalleled level of unanimity in the outlook for monetary policy. All 17 current Fed policymakers see the key overnight interest rate, or federal funds rate, remaining near zero through next year, and 15 of 17 see no change through 2022.

Even in the depths of the 2007-2009 financial crisis and recession some policymakers raised a cautionary flag about the need for higher interest rates to guard against inflation.

This time that debate has disappeared. The Fed's preferred measure of inflation is expected to be a weak 0.8 percent this year, compared to the central bank's goal of two percent, and rising to just 1.7 percent at the end of 2022.

At this point "we are not even thinking about thinking about raising rates," Powell said.

The decision to leave the policy rate unchanged on Wednesday was unanimous. The central bank also began shaping the longer-term measures it will use to keep the recovery as strong as possible. Officials promised to maintain ongoing Fed bond purchases at least at the current pace of around 80 billion U.S. dollars per month in Treasuries and 40 billion U.S. dollars per month in agency and mortgage-backed securities – levels that may be increased later, or supplemented with other strategies.

While growth may resume this year, policymaker forecasts show the rebound beginning in earnest in 2021, with economic growth for the year forecast at 5 percent.

Notably, the Fed did not mark down its long-run estimates of full employment, trend growth or the federal funds rate, a sign officials feel the country may escape permanent economic damage from a health crisis that has killed more than 112,000 in a few months.

"Their messaging is we are keeping rates low, but this is going to work, it is going to get us there," said Bruce Monrad, chairman and portfolio manager at Northeast Investors Trust in Boston.

On Wall Street, which had been near unchanged ahead of the Fed's statement, stock prices ended mixed. The benchmark S&P 500 index was down about 0.5 percent whereas the Nasdaq Composite was up about 0.7 percent. Yields on U.S. Treasuries slipped and the dollar fell against a basket of currencies.

The pledge to keep monetary policy loose until the U.S. economy is back on track repeats a promise made early in the central bank's response to the coronavirus pandemic.

That response included cutting interest rates to near zero in March and making trillions of dollars in credit available to banks, financial firms, and a wide array of companies.

Powell said that while much remains uncertain, particularly the progress of the pandemic, the fiscal and monetary response has been working well so far, maintaining income support for the unemployed and limiting business failures so far.

More may be needed, he said.

"This is the biggest economic shock in living memory," Powell said. The response "has been large, forceful and very quick ... In a class by itself."
