The prices of groceries took an upward tick, while overall prices in the United States fell 0.8% in April because of decreases in the price of gasoline and oil, CNBC reported.
"Food price gains were robust as we know there are empty shelves out there," Peter Boockvar, chief investment officer at Bleakley Advisory Group, told CNBC in an email. "Demand we know in most areas of the economy has collapsed and prices are falling in response."
Blame the higher prices on stay-at-home orders and the closure of restaurants. More Americans began cooking at home, but food producers and farmers were unable to keep up with the demand of shifting deliveries from restaurants to grocery stores, CNN reported.
Panic buying has not helped. Customers hoarding different kinds of foods have created shortages.
"In areas where demand has hung in, like 'food at home,' we have inflation because the supply side has been damaged, whether directly via infected facilities or because of the higher costs of finding freight capacity," Boockvar told CNBC.
