The St Louis Fed has the goods on tomatoes, you would expect that: https://fred.stlouisfed.org/series/WPU02440127
The PPI for tomato sauce, which had been very much constant between 1980 and 2020 (annual increase ~ 1 %) went up by 50 % between mid-2021 and January this year. There is no reason for it to go up, except the grocery monopoly and sticky prices. Of course I want it to come down, the increase isn't due to factors at the producer side.
Here's the price for eggs: https://fred.stlouisfed.org/series/APU0000708111
At least there the recent increase is explainable by bird flu, but no one expects prices to come down once the epizootic is over.
And there are areas where you want deflation, just to discourage investment. Housing is not supposed to be an investment vehicle.
