If you ran a cartel, what would your biggest fear be? If it were me, my biggest fear would be getting regulated out of existence, or maybe even being criminally prosecuted. So you want to keep a low public profile for your cartel activity.
If you start ratcheting up prices without an excuse, eventually people would notice, and at some point "people" would start to include state and federal legislators, who will start asking uncomfortable questions and whom you might not be able to buy off forever.
So instead what you do is set a comfortable minimum price industry wide and use your cartel power instead to aggressively cut costs, so that you have a credible threat of crushing any competition in a price war. This keeps potential competitors in check, thereby tacitly maintaining your preferred price floor.
When an external event does happen that actually raises supply costs, you are best equipped to eat those cost increases while your competitors struggle. Eventually, you sadly announce that you must raise your prices. This price becomes the new price floor for a while, until inflation catches up.
I'm not saying that's what they're doing, but to me that seems like a nice balance between maintaining industry dominance and not being portrayed in the media as Dr. Evil.
The first line of the article is "Since 2020, Americans have experienced rising food prices". The pandemic's effects largely started in March 2020. "Now" is scoped to "that last couple of years", not "last week".
Again, the cartel(s) existed (and they've long been accused of price fixing of various kinds; BigAg price fixing fines are not new; https://en.wikipedia.org/wiki/Lysine_price-fixing_conspiracy as an example). The handy "it's the pandemic's fault prices are going up everywhere" excuse to get away with big price hikes was new.
They didn't need excuses to raise prices, this explanation still doesn't explain why they waited. Cartel's don't care what their consumers think since they've cornered the market on an inelastic product.
