Spending in the US is broadly concentrating around the top maybe 10% of consumers, who are the only ones left in the economy with disposable income. This means for a lot of merchants that higher percentages of their transaction value is coming from those higher tiers of cards, which attract higher interchange fees on the rate table. As that average interchange fee paid drifts up, acquirers increase their fees to merchants at contract renewal to compensate for that.
