### Tape / Session Read Mastercard (NYSE:MA) is confronting a proposed £5 billion collective action in the UK legal system filed on behalf of approximately one million merchants seeking to recover multilateral interchange fees. The claim centers on how the global payments network prices transactions for UK businesses as transactions move toward digital channels.
### Why This Lane Matters Legal scrutiny of interchange fees hits directly at the mechanics of card network pricing power and net margins.
