Logistics Managers' Index helping to track supply chain changes

Consumers will most likely feel the effects of tariffs by late September, says a W. P. Carey supply chain expert.

In this story aired July 17, 2025, on Arizona Horizon:

I think the headline from May and June is that upstream in the supply chain we're seeing people hold a bunch of inventory — upstream means that suppliers, and suppliers' suppliers, and so on — and we're also seeing increased inventory costs. So, I'm not surprised by the fact that inflation ticked up a little bit. Truthfully, the stock market doesn't think the tariffs are a big deal, but we think they're going to start biting by the end of August and September. We're going to start seeing, as we move into the fall, those tariffs bite because we can see that the cost of inventory increased dramatically during May and June, and that takes a while to wind its way through the supply chain.
