With respect to those numbers, I remember this recent accusation of price-fixing across 2019-2021 [0] that might have an effect, although I also have reservations about how much to trust anything coming out of the rotting US Department of PresidentsPersonalLawyers these days.
The Iran war is for sure a huge part of that (just look at the energy cost inflation!), but other elements are a factor too. "Months ago" is really not that long when it comes to inflation.
