Mastercard: the efficiency ratio inflected without a restructuring charge

Operating leverage in a bank is the gap between revenue growth and expense growth, and it is durable only when the expense base has been structurally reset rather than temporarily suppressed. The expense evidence is that there was no charge. Revenue outgrew expenses without a restructuring item, which distinguishes this from the three prior attempts. The position: long on Mastercard, entry locked at publication and the exit dated rather than open-ended. The target is stated in the call block above and the horizon with it. Sized to the catalyst rather than to conviction, with the invalidation written into the kill-switch card instead of left implicit. A credit cycle would overwhelm the operating leverage argument entirely, and expense discipline is the first thing to break when revenue falls.
