WASHINGTON, April 26 (Reuters) - The U.S. economy likely maintained a moderate pace of growth in the first quarter, which could further dispel earlier fears of a recession even though activity was driven by temporary factors.

The Commerce Department's gross domestic product (GDP) report to be published on Friday at 8:30 a.m. EDT (1230 GMT) is expected to sketch a picture of an economy growing close to potential, mostly reflecting the impact of an ebbing boost from a giant fiscal stimulus and past interest rate increases.

Gross domestic product probably increased at a 2.0 percent annualized rate in the first quarter as a burst in exports, strong inventory stockpiling and government investment in public construction projects offset slowdowns in consumer and business spending, according to a Reuters survey of economists.

With global growth still sluggish, the surge in exports is likely to reverse and the inventory build will probably need to be worked off, which could curtail production at factories. That could restrain growth in the second quarter.

The economy grew at a 2.2 percent pace in the October-December period. Growth has stepped down from a peak 4.2 percent pace in the second quarter of 2018, when the White House's $1.5 trillion tax cut package jolted consumer spending.

Economists estimate the speed at which the economy can grow over a long period without igniting inflation at between 1.7 and 2.0 percent. The economy will mark 10 years of expansion in July, the longest on record.

"The economy remains solid, but we anticipate a slowing in the pace of growth in the medium term as the tailwinds from fiscal stimulus fade and the headwinds of tighter monetary policy take hold," said Sam Bullard, a senior economist at Wells Fargo Securities in Charlotte, North Carolina.

The economy stumbled at the turn of the year, with a batch of weak economic reports suggesting first-quarter GDP growth as low as a 0.2 percent rate. The soft data stream stoked fears of a recession that were also exacerbated by a brief inversion of the U.S. Treasury yield curve.

Some of the weak data, especially retail sales, were blamed on a 35-day partial shutdown of the federal government, which hurt confidence and delayed processing of tax refunds. Since the shutdown ended on Jan. 25, economic data have mostly perked up, leading to a sharp upgrading of first-quarter GDP estimates.
