Meta’s Muse will move your money. Banks already do.

Forget about PFM (as if you haven’t). The trendiest thing in money management is the AI personal assistant. Already, an AI agent offers recommendations on how consumers spend, how they should budget and which subscriptions to ditch. Right now, Meta’s Muse is the queen bee with more than 6.6 million global downloads since its launch on September 8.

It’s easy to think that Muse, ChatGPT’s finance tools, Instinct and whatever comes next will make digital banking as we know it dead. Drop-down menus? Never liked you for budgeting anyway. In less than a month, Muse has proved the technology is mainstream. If AI agents are useful, they keep building up levels of trust. First it recommends a restaurant, then it pays rent. Each positive experience raises the dollar amount at which people want to approve the purchase themselves.

"This #1 app needs to alter bank AI strategy,” writes Chris Nichols, president of Institutional Banking at SouthState Bank, on LinkedIn. “At some point, banks at least need to make themselves more understandable to agents before they allow money movement.”

As some see it, what’s at stake is deposit flight: customers who’ve stuck with the same bank decade after decade will finally move their money. Apollo Chief Economist Torsten Slok caused a ruckus when he warned that agents such as Muse could make bank runs likelier because, in time, they could automatically move money on consumers' behalf into higher yields. That would hurt a bank that relies on cheap deposits. But the concern is far from universal. Ethan Bloch, who is building personal finance at OpenAI, tweeted on X that consumers want a brand they trust with their savings and instant money movement in and out of checking – a speed that doesn’t exist when someone holds their savings at another bank. “Agents don’t change any of this,” Bloch wrote.

The AI agent fantasy already has cracks. Shane Mac, a startup CEO, said Grok Bot, SpaceXAI’s “always-on agent,” shared his personal finances on Slack. With his staff.

And yet, there’s no turning back.

While Muse can see consumers' money (and suggest where to bank), it can't move it between accounts yet. Banks can. That gives banksthe right to win even as these agents influence the way people manage money. They have the data Plaid passes along and plenty that never leaves their core. And consumers would rather trust their bank than hand more sensitive data to Meta and other tech giants.

Some banks will want to block Muse and other AI agents, cautioning their customers not to share their financial information. Already, JPMorgan Chase CEO Jamie Dimon said the bank has limits for outside agents. "We're not going to allow just any … outside agent to come in inside the company, because it's just too risky for clients and for JPMorgan,” Dimon told analysts on the bank's third-quarter earnings call.

But warning consumers to stay away from AI agents altogether is like setting a curfew for a 35-year-old. Financial institutions can’t stop their customers from asking agents where to bank or how to build a better budget. And they can’t stop agents from deciding what becomes table stakes in a digital experience.

In an upcoming Yours in Finance interview,Brett King, author of “Bank 5.0: The Rise of the Agentic Bank,” told me that by 2030, there will be more agents as customers than humans. “If you are trying to block agents, then it’s like blocking customers. It doesn’t really make any sense,” King said. “So, you have to figure out a way to do that safely.”

Not just anything goes. It’s banking.

Jordan Wright, CEO and co-founder of Atomic, believes banks ought to get treated differently from the rest of the authenticated web when it comes to what agents can do. Imagine a SVB-style run when Muse is optimizing the finances of 20 million Americans and one X post questions a bank’s liquidity. "Muse uses that as a signal to move money to a ‘safer’ account, but across millions of customers of that bank, possibly on a rumor that may not even be well-founded. Bank topples,” Wright writes on LinkedIn. “We need stability and accountability in order for banking to operate the right way.”

As Wright sees it, regulations or safeguards that bank-set safeguards against mass money movement may be needed. "Should consumers have access to their own data? Yes, absolutely,” he writes. "Should we be careful about how agents enable money movement? Yes, absolutely. To do otherwise would create chaos in a fragile financial system.”

And banks are starting to think about offering alternatives. PSECU, a credit union in Harrisburg, Pennsylvania, is gearing up to be one of the first institutions to offer members a way to manage their finances with Google Gemini, including suggestions about how to pay down debt faster.

Mercury, a business banking fintech firm that won conditional approval for a national bank charter in April, went further: Now, customers can manage their accounts, including making payments and transferring money from within ChatGPT as long as they approve every transfer from within Mercury, Bloch said on X.

Theodora Lau, founder of Unconventional Ventures, encourages others to follow suit. As she wrote on LinkedIn: “Financial institutions need to work with frontier models to stay competitive. Having this conversation within the walls of the institution, with the data and governance that come with it, is far better than having the agent run from the big tech provider's side.”

Banks lost the PFM round, partly because they buried the features within their apps and required too much effort from consumers to make the tools work. Pie charts never took center stage. What’s different now is the ease and speed with which an app can cancel a subscription or save on another bill. With consumers juggling multiple money products, that is banks’ opening to become the primary interface that performs other tasks, one that includes securing consumers discounts on their cell phone plans.

For the banks betting on these experiences, embracing bold marketing matters, too. Take a cue from Muse and its #MuseMoneyChallenge, which invites consumers to share how much the agent saved them. Banks can do that, too.

Banks win, of course, only if their experience is good and actually saves customers money and time. Nobody wants an annoying chatbot. But this time, banks have a real shot.
