Stocks, bonds decline amid price pressure concerns

The technology sector continues to lead the retreat in equities, with Apple and Microsoft pacing declines in the Nasdaq 100. Cathie Wood's ARK Innovation ETF resumed its slide, bringing this year's loss to about 18%. After closing at a record high on Friday, the benchmark S&P 500 slumped the most since Feb. 25. Energy was the only one of the 11 industry sectors in the green. Treasury yields moved briefly off the highs of the day after a successful 10-year note auction.

"The markets have been hovering around all-time highs with a lot of the reopening trade already priced in," said Mike Loewengart, managing director of investment strategy at E*Trade Financial. "So it's not out of the question that the outsized inflation read could bring us back down to earth a bit."

The debate over whether inflation will be persistent enough to force the Federal Reserve to tighten policy sooner than current guidance suggests comes as abundant stimulus has powered a rally in global equities, raising concerns valuations had become expensive. Fed Vice Chair Richard Clarida said he was surprised by the rise in consumer prices and "we would not hesitate to act" to bring inflation down to its goals if needed.

The consumer price index increased 0.8% from the prior month after a 0.6% gain in March. Excluding the volatile food and energy components, the so-called core CPI rose 0.9% from March.

"The CPI data point feeds into a myopic narrative that the U.S. is overheating and the Fed is one step away from tightening," said Mike Bailey, director of research at FBB Capital Partners. "Bears will feast on this tightening theme in the short term, but my sense is inflation will prove fleeting and markets will revert back to a more bullish view of moderate growth and lower risk of Fed tightening until we get to a full recovery."

Elsewhere, the claim among advocates that Bitcoin is an inflation hedge appears to be in question after the CPI report. The digital asset slumped as much as 5.8% to around $53,600.

European stocks closed mostly higher, lifted by optimism about economic re-openings and booming commodities.

Copper and iron ore were on course for records amid a broadening commodities boom. Oil was steady above $65 per barrel. The biggest U.S. pipeline is still closed in the wake of a cyberattack, leading to acute fuel shortages in some parts of the nation.
