Most people think “risk” is about markets going up and down. Stock prices bouncing around. Red numbers. Headlines.

But that’s not how I think about it.

In my world, risk isn’t volatility. It’s fragility. It’s the chances of your current plan breaking. What puts you on the back foot when life doesn’t go to plan.

Volatility is just noise. Sometimes annoying, but rarely dangerous if your system can absorb it.

What Real Risk Looks Like (In My Life)

Here’s what actually feels risky to me, right now:

1. Needing two full incomes to stand still

This is the big one for us. When I think about real financial risk, this is where my mind goes first.

Our life works because we both earn decent money. That’s the deal. We’re not especially lavish, but there’s a mortgage, childcare, bills, family stuff, the occasional treat. Take one income away, even for a short while, and the plan starts to wobble.

Right now, we couldn’t maintain this setup long-term on one salary. Not without major changes. That’s not a crisis in the short term – we’ve got decent cash savings and our ISAs give us a good level of flexibility. There’s an emergency buffer we could lean on for a few months, and we wouldn’t need to panic. But those reserves are there to buy time, not to make a new lifestyle sustainable.

And that’s the risk. Not just the loss of income itself, but what it says about the structure we’ve built. It’s a version of financial fragility that doesn’t show up in spreadsheets – a lack of freedom to take a step back, or try something vocational, or just breathe a bit more.

It also means that if something major happened, a long-term illness, a period of unemployment, or even just one of us wanting to downshift, whilst we’d eventually run into difficult choices. The worst case is having to sell the house. That’s not something we lie awake worrying about every night, but it’s there in the background. And it shapes how we think.

The reality is, most people are in this position. This is normal. Most households rely on two incomes, and will do so for most of their working lives. The difference, I think, is that we talk about it openly and actively try to shift out of it over time.

That’s also why I think the FIRE philosophy is useful, even if the “retire early” bit doesn’t feel especially realistic. At its core, FIRE is about building a life that isn’t dependent on full-time, high-earning jobs to function. It’s about giving yourself more choice. And that resonates. We’re not financially independent, not even close, but we think about how to get there. Not in 30 years – sooner, if we can. Even if it’s 10 or 15 years away, that’s still a meaningful shift.

So when we talk about risk, for us it’s not volatility, or fund selection, or even inflation. It’s this: what would it take to live well, securely and calmly, without needing to be “on” all the time?

That’s the question we keep coming back to.

2. Under-investing for the future

I’ve chosen to go hard on pensions via salary sacrifice, it’s the best risk-free return available. That’s a long-term play, and we’re locked in. But to me, not investing or hoarding cash indefinitely is riskier. Over time, inflation eats more quietly than a bear market, but it’s just as real. And the long-term lock-up of my capital in a wrapper I can’t access right now does create fragility and risk.

3. Making bad decisions under pressure

I’m not immune to panic. I know myself. Which is why I build in speed bumps:

• I don’t check markets daily.
• Big money decisions are run past my wife.
• If I want to change course, I spend a lot of time reflecting and analysing why. I keep revisiting and talk it through with friends for 2nd opinions.

If it still makes sense, then I go ahead. Often it was my ADHD brain getting over excited and the urge fades.

Volatility Is Loud But Unimportant

Markets wobble. It’s normal.

Our investments are in default “adventurous” plans – global equity-heavy blends that do what they say on the tin. They’re not exciting, but they work. I don’t tweak them. I don’t try to time anything.

The real risk isn’t a bad quarter, it’s pulling out halfway through the plan and never getting back in. “Dollar-cost-averaging” is my answer to this and I don’t think about the volatility too much. You win some, you lose some, it’s all the same to me.

The Institutional View (Adapted to Real Life)

In institutional investing, we talk about risk as factors:

• Liquidity risk: can we access money when we need it?
• Sequencing risk: does a bad market crash early in retirement derail the whole thing?
• Concentration risk: are we overexposed somewhere we don’t realise?

I think about all of these in my own finances – just without the slide decks:

• I don’t put all our liquidity into ISAs or pensions – we keep some flexibility. I have a flexible cash ISA fully loaded if needed, we have a cash buffer usually of between 1 and 6 months expenses, we have our investment ISA’s and some premium bonds. All in all a decent mix of liquidity options immediately to counter the pension inaccessibility.
• I front-load investing while we’re in peak earnings years, knowing later might be lumpier if we want a break or get made redundant.
• I stay diversified. I’m not immune to the occasional ‘stock selection’ but generally that’s in a separate account and my real ‘savings’ are in passive, diversified funds.

You don’t need a Bloomberg terminal to think clearly about risk. You just need to look at how your life actually works.

An Example: Overpaying the Mortgage vs Investing

We’ve had this conversation more than once.

Do we overpay the mortgage, or put more into ISAs?

Mathematically, investing usually wins.

But risk isn’t always about numbers, sometimes it’s pure psychology. Also, interest not paid on the mortgage is safer than T-bills, you can’t get a lower form of risk than not having debt in the first place.

Overpaying the mortgage gives us more certainty. Fewer monthly outgoings down the line. More flexibility if one of us wants to change pace later. Also at high income tax levels and high interest rates it’s really not that bad.

So we have done a bit of both. Invest steadily, but overpay too.

That’s not optimised. But it’s robust and feels more secure.

My Actual Risk Framework (Informal, But It Works)

Final Thought

You can’t remove risk from your life – financial or otherwise.

But you can choose the risks that serve you. You can reduce the ones that quietly erode your confidence, flexibility, or ability to respond when life shifts.

Volatility isn’t the enemy. Panic, rigidity, and poor decisions under stress are.

My advice? Build a system that holds up when things wobble. Then leave it alone and get on with your life.
