This is largely due to TSMC, who according to DigiTimes, will be increasing the costs of its chip production by as much as 20%. Given that Apple almost exclusively relies on TSMC for their chipsets, this means that Apple will more than likely be affected by these price changes, and obviously they will not be absorbing the costs.
The changes are expected to go into effect in January 2022, but it is said that Apple might attempt to offset those costs by factoring that into the price of the iPhone 13. We’re not sure how much more expensive the iPhone 13 will be, but if there is a price hike, you shouldn’t be surprised.
We’re sure that Apple can’t be pleased that TSMC is increasing its prices, but at the same time, TSMC played a large role in helping Apple stay ahead of the curve with its chipset manufacturing processes, so we guess that’s the price Apple will have to pay.
