Pent-up demand, shortages fuel U.S. inflation

By Lucia Mutikani

WASHINGTON (Reuters) - U.S. consumer prices surged in April, with a measure of underlying inflation blowing past the Federal Reserve's 2% target and posting its largest annual gain since 1992, because of pent-up demand and supply constraints as the economy reopens.

The strong inflation readings reported by the Commerce Department on Friday had been widely anticipated as the pandemic's grip eases, thanks to vaccinations, and will have no impact on monetary policy. Fed Chair Jerome Powell has repeatedly stated that higher inflation will be transitory.

The U.S. central bank slashed its benchmark overnight interest rate to near zero last year and is pumping money into the economy through monthly bond purchases. It has signaled it could tolerate higher inflation for some time to offset years in which inflation was lodged below its target, a flexible average.

The supply constraints largely reflect a shift in demand towards goods and away from services during the pandemic. A reversal is underway, with Americans flying to vacation destinations and staying at hotels among other activities. Year-on-year inflation is also accelerating as last spring's weak readings drop from the calculation.

"Many goods are in short supply amid very strong demand and supply chain disruptions, and some services prices are up sharply as consumers start to go out again," said Gus Faucher, chief economist at PNC Financial in Pittsburgh, Pennsylvania. "Shortages of labor in some industries are also contributing to higher prices. But many of these factors will prove transitory, and inflation will slow in the second half of 2021."

Consumer prices as measured by the personal consumption expenditures (PCE) price index, excluding the volatile food and energy components, increased 0.7% last month amid strong gains in both goods and services. That was the biggest rise in the so-called core PCE price index since October 2001 and followed a 0.4% gain in March.

In the 12 months through April, the core PCE price index vaulted 3.1%, the most since July 1992, after rising 1.9% in March. Economists polled by Reuters had forecast the core PCE price index rising 0.6% in April and surging 2.9% year-on-year.

The core PCE price index is the Fed's preferred inflation gauge.

Stocks on Wall Street were trading higher, though gains were capped by the rising price pressures. The dollar rose against a basket of currencies. U.S. Treasury prices were higher.

"Inflation is up, but real yields are still low," said Jamie Cox, managing partner at Harris Financial Group in Richmond, Virginia. "This is basically the transitory sweet spot."
