June/July 2021 is when it really started accelerating. Since the official quoted number is the 12 month rolling number, they are really fucking up if they don't get it flattening out against the baseline now.
I do think the topline number will begin to flatten/slow, but part of what is happening to do that is that there are segments of goods that are having wild discounting going on, and others where the price will continue to exponentially increase (the ones that matter) that will balance out. There have been a ton of bad inventory purchasing related decisions made the last 18 months. CEO's said to avoid out of stocks at all costs, while China pretty much tripled its minimum order quantities on anything plastic resin related as an example. There's a glut of bad inventory on everyone's books, and with interest rates going up, it won't be as cheap to hold it. Major retailers are already cutting their week of supply because they can pass that cost down to suppliers. So consumers will benefit from the upcoming discounting purge, but the cost will be lots of jobs.
