Egg prices have entered the zeitgeist.

Comedian Trevor Noah told Taylor Swift at the Grammy Awards on Sunday that the popstar has "the best fans in the world," subsequently asking if they can help reduce the high price of eggs.

"They'll get on it," Swift said.

Unfortunately, factors influencing egg prices at the grocery store are likely beyond the control of "Swifties."

Here are three things to know about egg prices right now.

In December, the average consumer paid a record $4.25 for a dozen large Grade A eggs, according to monthly U.S. Bureau of Labor Statistics data. The price more than doubled from $1.79 a year earlier.

Egg prices rose faster than almost any other good or service in the U.S. economy in 2022.

Here's why Swifties are bound to have little impact: High egg prices are largely the result of a deadly and historic outbreak of avian flu in the U.S.

Over 44 million egg-laying hens have died from the disease since February 2022. (Think of it like a lethal and highly contagious equivalent of the flu for humans.)

Outbreaks persisted through the year, which is rare — they usually wane by summer. The supply shock coincided with peak seasonal demand around the winter holidays. Lower supply plus higher demand meant higher prices.

Higher costs for animal feed, labor and transportation also played a role — as they have in broader food inflation, too.

Even before Noah asked Swift to intervene, there have been signs that price pressures are easing.

Wholesale egg prices — basically, the price supermarket chains and other stores pay to acquire their supply — have fallen significantly (by more than 50%) from their peak in mid-December.

There haven't been new confirmed cases of bird flu among commercial table-egg farms since December, giving suppliers time to recover. Consumer demand has also declined as a sort of backlash against high prices, the U.S. Department of Agriculture said last week.

It typically takes several weeks for price movements in the wholesale market to flow to the retail market for consumers.

But there are reasons why it may take longer — perhaps months — for retail prices to drop noticeably, according to food economists. For one, demand generally rises leading up to Easter, which falls on April 9 this year.
