Coalition loyalty
A coalition programme is one shared currency accepted across multiple unrelated brands, so members earn in one place and spend in another.
The appeal is obvious from the member's side. A currency earned at the supermarket, the fuel station and the airline accumulates far faster than any single brand could deliver alone, which means rewards arrive within a timeframe a person can actually care about.
The difficulty is structural rather than operational, which is why coalition programmes keep failing for reasons that look different each time and are not. Somebody has to own the currency, and that owner sets its value. Every partner is simultaneously buying points from the operator and selling attention to it, and those two prices move in opposite directions. Add a partner who issues far more than they redeem and the economics shift under everyone else without any of them agreeing to it.
Europe has a longer and more successful coalition history than the United States, and the surviving programmes tend to share a trait: a dominant anchor partner with enough volume to absorb the imbalance. Coalitions assembled between equals appear to fare worse, though we have not yet computed survival rates across the directory to say so with a number. That study is planned, not done.
The arithmetic is what breaks coalitions. Take 6 partners sharing one currency where the operator sells points at 1 cent and redeems them at 0.7 cents. Every partner issuing more than it redeems is funding the ones doing the reverse. Add a 7th partner with high issuance and low redemption and the imbalance widens for all 6 without any of them agreeing to it.
