NEW YORK, RAW – The S&P 500 has closed lower as rising commodity prices and labour shortages prompted fears that despite reassurances from the US Federal Reserve, near-term price spikes could morph into longer-term inflation.

While all three indexes pared their losses from session lows, the sell-off was fairly evenly dispersed across the sectors.

“Today feels like a catch-up in that tech has been weak so far this month and it’s finally spilled over into other areas of the market and we’re seeing broader weakness,” said Ryan Detrick, senior market strategist at LPL Financial in Charlotte, North Carolina.

Economic data released on Tuesday from the Labor Department showed job openings at US companies jumped to a record high in March, further evidence of the labour shortage hinted by Friday’s disappointing employment report.

The report suggests labour supply is not keeping up with surging demand as employers scramble to find qualified workers.

Burrito chain Chipotle Mexican Grill announced it would hike the average hourly wage of its workers to $US15 ($A19), a further sign that the worker shortage in the face of a demand revival could add fuel to the inflation surge.

That worker shortage, along with a supply drought in the face of booming demand could contribute to what is seen as inevitable prices spikes, which the US Federal Reserve has repeatedly said are unlikely to translate into long-term inflation.

“The inflation concerns continue,” Detrick said.

“The supply chain issues coupled with record stimulus coupled with apparently a tighter labour market have all contributed to fears that inflation could trend higher over the (northern hemisphere) summer months.”

“I don’t think (the market) believes the Fed when it says they won’t raise rates until after 2023,” Detrick added.

“That could be where the market and the Fed do not see eye to eye.”

Market participants will scrutinise the Labor Department’s CPI report, due on Wednesday, for further signs of potential inflationary pressures.

The Dow Jones Industrial Average fell 472.21 points, or 1.36 per cent, to 34,270.61, the S&P 500 lost 36.33 points, or 0.87 per cent, to 4,152.1 and the Nasdaq Composite dropped 12.43 points, or 0.09 per cent, to 13,389.43.

The CBOE Volatility index, a measure of investor anxiety, touched its highest level in two months.

First-quarter reporting season, which is providing the first year-on-year comparison to pandemic-related shutdowns, is approaching the finish line with 451 constituents of the S&P 500 having reported.
