Here is how banking really makes money. It is not the lobby. It is not the free toaster. It is the pipes — and, better still, the legal exemptions bolted to the pipes.
JPMorgan, Bank of America, Wells Fargo, and PNC are in preliminary talks to buy a payments network from Fiserv. That network owns the STAR and Accel debit rails — the wiring that moves money when a debit card is swiped.
On the surface, that is four banks buying plumbing. Underneath sits a law called the Durbin amendment.
The loophole
Every time you swipe a debit card, the store’s bank pays a small charge called an interchange fee — the toll on the swipe. Since 2010, the Durbin amendment has capped that toll for banks with $10 billion or more in assets.
Interchange sounds tiny — pennies per swipe. Multiply those pennies by every debit card in America, every day, and the cap costs the industry billions of dollars a year.
But the law has a door in it. A bank that owns a payment network is exempt from the cap entirely.
So the prize here is not technology. It is a legal exemption with pipes attached.
There is fresh precedent, too. Capital One’s $50.6 billion purchase of Discover bought exactly this kind of exemption along with the card business.
And the timing is no mystery. Fiserv is down roughly 70% over the past year. That is how a payments network lands on the discount rack in front of four of America’s biggest banks.
Banks really, really dislike this cap. When it first hit, Bank of America floated a $5-a-month debit-card fee on customers. The backlash killed that fee in weeks. Owning the network is the quieter path to the same dollars.
Why you care
Two reasons. First, as a customer: fees flow downhill. If billions in swipe revenue come back to the banks, it gets priced somewhere. Glance at your own accounts’ fee schedules once a year with that in mind.
Second, as an owner. This is the whole thesis behind the financial names in our income holdings. We want businesses that collect a toll on every transaction — rain or shine, boom or bust.
Think of a toll road. The road does not care whether the cars are new or old, or where they are going. It gets paid per trip. Payment networks work the same way, swipe after swipe.
We do not want the ones that must guess interest rates correctly to earn a living. Toll collectors get paid either way. The pipes do not have bad quarters. That is how a portfolio earns income without drama.
The one caution
A moat built by statute can be unbuilt by statute. Watch how regulators react to this deal — and to the Capital One precedent — before assuming the toll is permanent.
These talks are preliminary and may go nowhere. The lesson stands either way. When banks buy plumbing, read the law behind the deal. The exemption is usually the asset.
