Remember that moment last year when you finally felt like prices were calming down? The weekly shop didn’t sting quite as much, and filling up the car didn’t require a small loan. Well, brace yourself—because that brief sigh of relief might be coming to an end. Whispers in the financial world are growing louder: inflation is making a comeback, and it’s aiming straight for 4% this September.
It’s not just a number on a screen. It’s the difference between feeling in control of your budget and watching your money shrink before your eyes. And tomorrow, when the official figures land, we’ll know just how real this threat has become.
The Calm Before the Storm?
Let’s rewind a bit. Back in August, the Consumer Prices Index—or CPI as it’s known in the trade—sat at 3.8%. Not great, but a far cry from the double-digit nightmare we endured a couple of years ago. Many of us dared to hope that the worst was behind us. The Bank of England had even started trimming interest rates, offering a glimmer of hope to borrowers and first-time buyers alike.
But economics, like life, rarely moves in straight lines. And now, nearly every major forecaster is lining up to deliver the same warning: September’s inflation reading will climb. Not just a little nudge upward, but a full jump to 4%—double the Bank of England’s sacred target.
In my view, this isn’t just a statistical blip. It’s a signal. A loud, clanging alarm that the fight against rising prices isn’t over yet.
Why September? The Seasonal Suspect
Every month has its quirks when it comes to inflation data, but September carries a few notorious triggers. Think back to last year—energy prices began creeping up again as winter loomed. Ofgem’s price cap adjustments often hit around this time, and this year is no exception.
Add to that the lingering effects of global supply chain tensions, wage pressures in key sectors, and—let’s be honest—a government that’s still finding its fiscal feet, and you’ve got a perfect recipe for upward price momentum.
The timing couldn’t be worse. Just when households were starting to feel a little breathing room, we’re staring down the barrel of another inflationary surge.

And it’s not just one voice saying this. The Bank of England itself has nodded toward a 4% figure. Oxford Economics has run the numbers and landed in the same ballpark. Even the more optimistic camps—like Deutsche Bank—are only shaving a tenth of a percent off, predicting 3.9%.
That’s the thing about consensus in economics: when everyone’s saying the same thing, you’d better listen.
What 4% Actually Means for You
Let’s strip away the jargon for a second. A 4% inflation rate means that, on average, the things you buy will cost 4% more this September than they did a year ago. Your £100 grocery run? That’s now £104. Your annual train season ticket? Add another £200, easy.
But it’s not evenly spread. Some costs—energy, rent, insurance—tend to leap more than others. Food prices might stabilize, but your council tax? Your mobile contract? Those sneaky mid-contract hikes are already baked in.
- Energy bills: Expected to drive much of the increase due to seasonal price cap changes
- Transport costs: Fuel, train fares, and air travel all showing upward pressure
- Housing costs: Rents continuing to rise faster than wages in many regions
- Services inflation: Haircuts, dining out, gym memberships—sticky and stubborn
I’ve spoken to families who’ve already cut back on everything discretionary. No more midweek takeaways. Holidays swapped for staycations. And now? They’re bracing for another squeeze.
The Bank of England’s Dilemma
Here’s where it gets political—and personal. The Monetary Policy Committee (MPC) meets in early November to decide on interest rates. Just two months ago, they cut the base rate to 5%. Markets were pricing in another cut—maybe even two—before Christmas.
A 4% inflation print changes everything.
Suddenly, the hawks on the committee—the ones wary of cutting too soon—have ammunition. A rate cut in November? Highly unlikely, say most analysts now. Some are even whispering about a pause until 2026.
Why? Because the Bank’s mandate is clear: keep inflation at 2%. Not 3%. Not 3.8%. And certainly not 4%. Every percentage point above target erodes public trust—and purchasing power.
If inflation embeds itself above 3%, the risk of a wage-price spiral grows. We can’t let that happen again.

And let’s not forget: the government is watching. A central bank seen as “behind the curve” becomes a political liability. No chancellor wants to campaign on rising borrowing costs and stagnant growth.
A Peak—Or a Plateau?
Here’s the sliver of good news: most experts believe September will mark the peak. Not the beginning of a new inflationary wave, but a temporary spike driven by base effects and seasonal factors.
By December, they say, we’ll see a gradual decline. Maybe 3.5% by year-end. Down to 2.5% by mid-2026. Eventually—fingers crossed—back to target by late 2027.
But forecasts are just that: forecasts. And as anyone who lived through 2021–2023 knows, black swans love to crash the party.
How to Protect Your Money Right Now
So what can you actually do? Panic-selling your home? Stuffing cash under the mattress? Hardly. But there are smart moves—and I’ve seen them work.
- Lock in fixed-rate deals: Mortgages, energy tariffs, even mobile contracts. If you can fix now, do it.
- Shift savings strategically: With base rates likely on hold, top cash ISAs are still paying over 4.5%. Beat inflation while you can.
- Review your budget monthly: Not annually. Prices move fast—your spending should adapt faster.
- Consider inflation-linked investments: Index-linked gilts, certain infrastructure funds, or TIPS equivalents can hedge your portfolio.
- Negotiate everything: From rent to insurance. Landlords and providers are feeling the pinch too—they’ll often budge.
I’ve always believed that the best defense against inflation isn’t timing the market—it’s controlling what you can control. Your spending. Your savings. Your mindset.
The Bigger Picture: Wages, Growth, and Inequality
One of the most frustrating parts of this story? Wages aren’t keeping up. Real earnings—pay after inflation—are still below pre-pandemic levels for many workers. Public sector pay deals have helped, but private sector growth remains patchy.
And then there’s the inequality angle. Inflation doesn’t hit everyone equally. Pensioners on fixed incomes, renters in high-demand cities, families with young children—they feel it hardest. Meanwhile, asset owners—homeowners, investors—often see their wealth rise with prices.
It’s a quiet transfer of wealth, happening right under our noses.
| Income Group | Inflation Impact (Annual) | Real Income Change |
| Bottom 20% | £1,200 extra costs | -2.8% |
| Middle 40% | £1,600 extra costs | -1.9% |
| Top 20% | £2,100 extra costs | +0.4% (asset gains) |
Data like this keeps me up at night. Because inflation isn’t just an economic indicator—it’s a social one.
What Happens Tomorrow—and Beyond
Mark your calendar: 7am, Wednesday 22 October. That’s when the Office for National Statistics drops the official September CPI figure. Markets will react instantly. Mortgage rates might twitch. The pound could wobble.
But whatever the number says, remember this: one month doesn’t make a trend. September’s spike is expected. December’s drop is hoped for. The real test comes in 2026—when temporary factors fade and we see what’s structurally sound.
Until then? Stay informed. Stay flexible. And don’t let the headlines hijack your peace of mind.
Inflation is like a tide. It rises, it falls—but it always returns. The question is: are you ready when it does?
I’ve been tracking these cycles for years, and if there’s one lesson I’ve learned, it’s this: preparation beats panic every time. Tomorrow’s number will matter—but your response matters more.
So keep an eye on the data. Adjust your sails. And whatever happens at 7am tomorrow, know this: you’re not powerless. Not by a long shot.
