The Megabanks Locked Out AI Agents. Community Institutions Shouldn’t.

Recently, the largest banks in America drew a hard line. JPMorgan Chase confirmed it blocks outside AI agents from acting on behalf of retail customers. Within days, Citi and Bank of America restricted agent access too.

If you run a community bank or credit union, you might read that as permission to do the same. I read it as the biggest opening our industry has had in a decade.

Your members are already using AI assistants to manage their lives. Those assistants check email, plan trips and compare prices. Banking is next. The only question is whether those agents come through you, or go around you.

Why the big banks closed the door

The stated reason is safety, and it’s a real one. Jamie Dimon warned about rogue agents, possibly thousands of them, acting on customer accounts. Nobody has settled who is liable when an AI-authorized payment goes wrong.

But look at the other reasons. An agent that checks balances all day and hunts for better rates can move idle deposits somewhere else in seconds. An agent sitting between the customer and the bank also means the bank no longer owns the experience: not the screen, not the messages, not the cross-sell.

So the megabanks chose control. They’re building their own agents and keeping everyone else out. That’s a rational move for a bank with a nine-figure technology budget and tens of millions of customers who aren’t going anywhere.

The wrong lesson for community institutions

Community institutions don’t win by copying the megabanks. They win by being easier, closer and more trusted.

If a member’s AI assistant can’t reach their account, the member doesn’t stop using the assistant. They work around you. They paste balances and screenshots into public chatbots, with no security and no oversight. Or they move their money to an institution that welcomes the assistant they already use.

Locking agents out doesn’t stop the future. It just decides that someone else will own your member’s experience of it.

Open doesn’t mean unguarded

The big banks are right about one thing: letting an agent log in with a member’s password is reckless. The answer isn’t a locked door. It’s a better door.

That means the institution, not the agent, sets the rules:

• Consent. The member decides which agents can connect and what each one can see.
• Limits. Agents get only the permissions they need, such as read-only balances or payments under a set amount.
• Approval. Anything that moves money waits for the member to say yes.
• Audit. Every action is logged, so the institution always knows what happened and why.

And it has to work at agent scale. Agents don’t log in twice a day like people do. They can check accounts constantly, so the infrastructure has to handle that volume without slowing down service for everyone else.

I’ve said before that proactive without trust is just surveillance with better marketing. The same is true here. Open without guardrails is just risk with a nicer name.

The real fight is over the deposit

An agent that hunts for better rates around the clock decides where the money sits, and every dollar that leaves the balance sheet is a dollar that can’t be lent back into the community.

The response can’t be to hide from that shift. Agent-ready infrastructure, with the guardrails above, gives community institutions something the megabanks have chosen not to offer: an open door, with the deposit still at home.

Which side do you want to be on?

For most of banking’s history, the best experience was a person: the banker who knew your name and called before a small problem became a big one. Digital banking lost some of that. AI agents can bring it back. Your member’s own assistant, working with your institution instead of around it, can notice, coach and act the way that banker did.

The megabanks have chosen to close up. Community institutions get to choose differently. Be the bank or credit union your members’ AI assistants can actually work with, safely and on your terms.

That’s the future we’re building at Bankjoy. And it’s the conversation I’ll be having with leaders from banking, credit unions and AI at our upcoming webinar on AI agents and the future of community banking. Stay tuned!
