When mortgage rates jump, your brain does something sneaky with the bill

The number that just landed

The Guardian reports that the average five-year fixed mortgage rate has hit 6% for the first time in three years, with Moneyfacts figures showing it is now at its highest point since September 2023.

That is a concrete number. And if you are self-employed, it probably landed somewhere in your chest, not just your head.

Why this hits differently when you work for yourself

For an employee, the mortgage is one line on a spreadsheet. For you, it is tangled up with everything. A slow month, a late invoice, a client who ghosts you, and suddenly that monthly payment feels enormous.

The Guardian reports that figures from the HomeOwners Alliance show the monthly cost of a £250,000 loan fixed at 6% for five years is £158 higher than the same-sized loan locked in at 4.94%, which was the average rate at the start of February. That is £158 every single month that was not in your plan at the start of the year.

And Moneyfacts finance expert Rachel Springall described the impact on rates as “brutal.”

So yes, this is real. And yes, your brain is going to try to protect you from it in a way that actually makes things worse.

The behavioural idea: present bias

Present bias is the tendency to prefer a smaller, immediate reward over a larger future one, or, in this case, to prefer the comfort of not dealing with something now over the discomfort of dealing with it later.

It is not laziness. It is wiring. Our brains weight the present much more heavily than the future. A cost that lands next year feels almost theoretical right now, even when the maths is right in front of us.

So here is what happens. You see the headline. You feel a little spike of stress. Then, because the stress is uncomfortable and you cannot fix it in the next five minutes, your brain quietly files it under things to sort later. You make a cup of tea. You check your messages. You move on.

And later never quite arrives.

Now, why does this matter so much for people like us? Because when you are self-employed, your financial life already has more moving parts than most. You are managing income that varies month to month, tax that sits in a mental pot somewhere, invoices that have not cleared yet. Present bias feeds on complexity. The more overwhelming something feels, the easier it is to defer.

The Guardian also reports that at the start of this year, many borrowers were expecting rates to fall. That expectation itself is worth examining. It is connected to what behavioural economists call optimism bias, the tendency to believe that future conditions will be better than current conditions. When you add optimism bias on top of present bias, you get a genuinely dangerous combination. You tell yourself it will probably be fine, and you tell yourself you will sort it later. Both feel reasonable. Neither is a plan.

The ostrich effect

There is another layer here too. Researchers Dan Galai and Orly Sade identified what they called the ostrich effect, the tendency to avoid information about potential financial losses because checking feels worse than not knowing.

Sound familiar? It is that thing where you roughly know your mortgage deal is ending soonish, but you have not actually looked up the exact date. Or you know rates have gone up, but you have not sat down and worked out what your new payment would be. The not-knowing feels safer than the knowing.

It is not weakness. It is the same brain that kept your ancestors from lying awake cataloguing every possible threat. Right now, though, it is keeping you from doing the one thing that would actually reduce the stress.

One small action for this week

Here is the thing you can do before Friday. Find the end date of your current fixed-rate deal and write it down somewhere physical. That is it. Not a spreadsheet, not a full financial review. Just the date, on paper, in front of you.

Because present bias loses some of its grip the moment you make the future feel real and close. A date on a piece of paper does that. It turns an abstract future event into something with a shape.

Once you have the date, you will know whether you have time to breathe or whether you need to move. And when you do move, talk to a qualified mortgage adviser or financial professional in your country who can look at your specific situation. I am a planner, not an adviser, and the specifics of what to do with your mortgage are genuinely a job for someone who can see your full picture.

The bigger pattern

If your money already feels chaotic, rate shocks like this one do not just create a financial problem. They create a psychological one too. The stress of not knowing is often heavier than the stress of knowing a hard truth.

That is the work I do with people in The Money Story Method, my 12-week one-to-one programme. We look at the beliefs and the behaviours underneath the chaos, not just the numbers. If that sounds like where you are, you can find out more at Way of Wealth.

Or if you just want a steady, grounding read every Thursday, The Thursday Money Note is a good place to start.

The rate is what it is. What you do with the information is still yours to choose.
