Consumers trust brands less when AI does the talking, yet a growing number of financial institutions are delegating their voice to AI, making AI-generated content both a reputation risk and a governance problem. Ironically, the sources AI trusts most in the financial area, from Investopedia to the Financial Times, won’t let AI write for them. Your bank shouldn’t either.

Key insight: AI is driving impressive efficiencies across financial services. But managing your institution’s reputation isn’t one of them.

I’ve spent more than 30 years protecting the reputations of global financial institutions and launching first-mover fintech companies. The companies that gained market share and momentum were deliberate about how they earned trust. They understood something their competitors didn’t: A great product still needs a believable story.

That matters even more now that customers use AI to compare credit cards, mortgage rates and auto loans.

Key insight: Your bank can win the AI answer and still lose the customer.

Need to Know:

JD Power reports 53% of customers turn to AI for financial advice, but only 27% trust it.
In a single year, the percentage of consumers saying heavy AI use makes them trust a brand less rose 95%.
Muck Rack found 99% of AI citations come from nonpaid sources with 84% drawing from earned media.

Where AI Is Earning Its Keep

AI provides real, measurable gains in fraud detection, underwriting support, personalized alerts, compliance documentation and back-office efficiency.

When something works, the instinct is to use it everywhere. If AI can draft compliance documentation, why not thought leadership material?

Key insight: However, they’re different jobs. Thought leadership requires more than accurate information. It requires expertise, real-world experience, and the judgment to know which position to defend. The value of brand communications lies in building a narrative that reflects what a bank stands for and earning validation to prove it.

AI can draft, summarize and repurpose content faster than any human. But putting it in charge of the narrative strips out the expertise, judgment and point of view that make your bank’s voice authentic.

Some bank leaders already see what’s at stake — the connection that produces trust. That connection starts with your bank’s voice, and that voice must be human.

Customers Are Already Asking AI About You

JD Power’s 2026 U.S. Financial Health Support and Advice Study found that 53% of customers are turning to AI for financial advice. A separate JD Power report, based on a 2024 survey, found that only 27% trust AI for financial information and advice, below travel at 37% and just above medical at 25%.

Why it matters: If you’re not citable, you don’t exist. That’s the stark reality of the answer economy.

Key steps for testing your AI visibility:

• Ask AI the questions your customers ask: “Compare the top three credit unions in Morris County, N.J., for a $30,000 auto loan over 60 months with a 700 credit score.” or “What banks in Akron, Ohio, offer the lowest rates for a 30-year fixed jumbo mortgage if I have a 740 credit score?”

• Run each prompt across ChatGPT, Claude, Gemini, Google AI Mode and Perplexity more than once. Research from AI visibility platform Profound found only an 11% citation overlap between ChatGPT and Perplexity, meaning a bank can dominate in one AI while remaining virtually invisible in the other.

• Record whether your institution or competitors appear in the answer, how you’re described, and which sources AI cites.

• Repeat the test every quarter to see whether your brand’s AI visibility is improving or declining.

Banks Are Only Solving Half of the Problem — and Blowing the Other Half

Marketing teams are tackling AI discovery with technical fixes, such as making content machine-readable with structured data and ensuring website pages are fully open to AI crawlers.

That helps a machine find your brand, but it doesn’t make the brand credible. And AI penalizes a brand with inconsistent or outdated messaging.

At the same time, AI has made content cheap to produce, and many institutions are racing to publish more of it. That’s the trap.

Volume is not differentiation. Feed similar ideas into the same models and everyone starts to sound the same. The more a bank publishes using AI, the more it sounds like the bank down the street. Gartner analyst Alan Lopez recently noted that if your content is vague or overly clever, AI “flattens it into something average.”

And the backlash is growing. A 2026 study published by Search Engine Land found that “AI content volume is now a brand trust liability,” with the percentage of consumers who say heavy AI use makes them trust a brand less rising by 95% in a single year.

Why it matters: Whether it’s a mortgage, checking account or auto loan, the real product is trust, and AI-generated content is eroding it.

Key steps for safeguarding brand trust:

• Audit everything you published last year. If another institution could have written it, your thought leadership is teaching the machines your brand is interchangeable.

• Ensure third-party sources like Trustpilot, Bankrate and Warrant’s Credit Union Directory tell a consistent story about your brand.

• Monitor AI answers about your brand and correct any sources giving stale or inaccurate information.

• Use social listening to track what customers are asking on community forums like Reddit and decide when and how your brand should join the conversation.

Earn the Authority and Validation AI Relies On

Consider who gets cited in the AI answers shaping your market. Conductor‘s financial industry and publishing benchmarks rank NerdWallet, Bankrate and Investopedia among the most-cited sources.

Key insight: The common thread is human accountability.

NerdWallet uses AI for research and editing, but human editors remain accountable; content is fact-checked and AI use is disclosed. Investopedia goes further and doesn’t publish any AI-generated editorial content. And the Financial Times has pledged that its journalism “will continue to be reported and written by humans who are the best in their fields.”

Independent news coverage, known as earned media, also helps determine what AI says about your bank. Muck Rack’s analysis of more than 25 million links cited across ChatGPT, Claude and Gemini found that 99% of citations come from nonpaid sources, with 84% drawing from earned media.

For example, a lender claiming it approves more thin-file borrowers is marketing. A journalist reporting on it gives the claim authority. A customer confirming it is offering validation.

Key insight: What others say about your institution carries more weight than anything you say about yourself.

Key steps for earning that validation:

• Audit your bank’s positioning and identify which customers, analysts or journalists support it.

• Partner with customers and let them tell their own success stories.

• Brief the analysts whose research shapes industry rankings, competitive positioning and customer decisions.

• Share original research with journalists and position subject matter experts to lead interviews.

Validation builds credibility, credibility builds trust, and trust earns you a place in the AI answer.

AI-Generated Content Poses a Reputation Risk and a Governance Problem

Financial institutions can’t afford hallucinated facts or invented citations. As Wells Fargo bank analyst Mike Mayo in an investor note, “AI failures at banks have greater downside than others since they erode a bank’s most important asset: trust.”

Why it matters: No AI policy can protect your reputation once human judgment leaves the process.

That makes AI-written content a governance problem for bank leaders.

Someone needs to own it. No bank would let AI sign its Call Report or approve its advertising. So why let it speak for your bank? A bank’s public voice requires the same accountability: a named executive who reviews it, signs off and owns the outcome.

Key insight: Accountability starts before approval. Human judgment must shape what your institution says and why it matters, from concept to final draft.

Human Judgment Is the New Luxury

Every financial institution has human capital: economists, data scientists and executives with decades of expertise. Consider what they know. A credit risk officer sees trends in proprietary lending data outside analysts might miss. A fraud specialist sees emerging threats as they target the institution. A lending executive can spot early signs of borrower stress months before they appear in industry reports.

AI can’t manufacture that expertise, and competitors can’t copy it. But if AI rewrites it into generic copy, or if that expertise is never shared, you’re handing the answer to your competitors.

Key steps for owning your reputation:

• Put someone in charge. Appoint an executive accountable for everything published in your bank’s name.

• Develop an enterprise-wide AI communications policy that defines what AI can assist with, such as research and editing, and what a person must own, such as writing and approval.

• Get the experts involved early. Engage with subject matter experts and executives at the outset of brand communications planning.

Bottom line: Banks and credit unions don’t need to slow AI adoption. They need to be intentional about it. Automate the legwork but keep human judgment in the driver’s seat.

It takes decades to build a reputation in banking, across regulators, investors and consumers. It takes far less to lose it.

The sources AI relies on most won’t let a machine write for them. Neither should the institutions asking people to trust them with their money.
