Stress and mental health: money strain showed up in bank records years earlier

Money changes can be an early clue about stress and mental health, in you or in someone close to you. A new study of bank records found that people who later told their bank about a mental health condition often showed signs of money strain up to 36 months before they did.

That does not mean a rough month with bills points to a diagnosis. It means that how we handle money can shift quietly when something else is going on, and that those shifts are worth noticing with kindness.

How the study worked

Researchers looked at deidentified records from a major UK bank. They compared customers who told the bank about a mental health condition between 2019 and 2025 with a much larger group of similar customers who did not. They tracked 331 monthly money measures, such as income, spending, credit scores and how people contacted the bank. The study was published Oct. 1, 2026, in JAMA Network Open. It can show patterns but not prove cause, and it only covers people who chose to tell their bank.

What they found

The differences were visible up to 36 months before the disclosure. Compared with the other customers, the people who later disclosed had:

• Lower credit scores. On the scale researchers use to compare different measures, the gap was -0.52.
• More overdraft use. The gap was 0.49.
• More income from disability benefits. The gap was 0.80.
• More contact with the bank by phone. The gap was 0.56.

They also used more cash and spent less on self-care and fun activities, like hobbies and recreation.

These numbers are averages across thousands of people. They describe a group, not a single person, and no one sign means much on its own.

One more result is reassuring in a practical way. The patterns looked broadly similar across different mental health conditions. Nearly all the variation came from which money measures were examined, and almost none came from which condition a person had. So you do not need to know the specific condition to understand what the money signals might look like: stretched finances, more calls to the bank, less spending on things that make life enjoyable.

Why would money and mood be connected?

Mental health conditions affect more than mood. They can make everyday money tasks harder, like paying bills on time, planning spending or resisting impulse purchases. And money worries add stress of their own. The two often feed each other.

The researchers suggest that banks could use this kind of information to offer support sooner, such as budgeting help or links to mental health services. Many banks already let customers tell them about a mental health condition so they can get extra support. It is still unknown whether offering help based on money signals actually works, and using financial data this way raises real privacy questions.

What you can do today

Pick one of these, whichever fits your life right now.

If you are thinking of someone close who seems different lately, such as more stressed about bills, pulling back from things they enjoy, or making unusual money choices, send a short, warm message. Something like “Thinking of you, how are you doing?” is enough. You do not need to mention money or solve anything.

If money worries are weighing on you, call your bank or credit union and ask what support options they offer for customers going through a hard time. Money stress is common and nothing to be ashamed of. Asking costs nothing, and you can ask for details before deciding on anything.
