Tomorrow the ONS drops the December 2025 CPI figures, and analysts are bracing for a rebound in UK inflation after November's unexpected dip. Will prices have climbed again just in time for Christmas shopping? The implications for your money could be bigger than you think...

Financial market analysis from 20/01/2026. Market conditions may have changed since publication.

Have you ever opened your latest grocery bill and felt that familiar pang – the one where you wonder how the same basket of essentials somehow costs noticeably more than last month? That quiet frustration has been a constant companion for many of us in the UK over the past few years. Tomorrow morning, the Office for National Statistics will pull back the curtain on December’s inflation numbers, and right now the big question hanging in the air is simple: did inflation rise again?

I’ve been following these monthly releases closely for a long time, and there’s always a mix of anticipation and dread. November surprised almost everyone by dipping to 3.2%, lower than most forecasts. So naturally, the chatter has turned to whether December snapped back upward. Analysts seem to think so, and the implications touch everything from your weekly shop to the Bank of England’s next moves on interest rates. Let’s unpack what we know so far, why December could look different, and what it might mean for ordinary people trying to make ends meet.

Why December’s Inflation Figure Matters So Much Right Now

Inflation isn’t just an abstract economic term – it’s the slow, steady erosion of what your money can actually buy. When it ticks higher, everything feels a little tighter. After months of gradual cooling, any uptick in December would signal that the battle against rising prices isn’t over yet. And with the Christmas period always prone to price fluctuations, many eyes are on this particular release.

In November we saw a welcome slowdown to 3.2% year-on-year. That was below what many had braced for, and it gave a small sigh of relief to households. But forecasts for December have clustered around 3.4% or even 3.5%, suggesting a modest rebound. If that proves accurate, it reinforces the idea that inflation remains sticky – especially in services and certain goods – despite broader progress.

What strikes me most is how sensitive we’ve all become to these monthly updates. A tenth of a percentage point here or there can shift conversations about pay rises, mortgage renewals, and even whether to dip into savings. It’s personal, even if the headlines treat it as macro.

A Quick Refresher: What Exactly Is CPI Inflation?

At its core, the Consumer Prices Index (CPI) tracks how much a typical basket of goods and services costs over time. The Bank of England targets 2%, because that level is seen as healthy – enough to encourage spending without spiralling out of control. Too low, and the economy can stagnate; too high, and purchasing power evaporates.

Unlike the headline number, core measures strip out volatile items like energy and food to reveal underlying trends. That’s why economists watch both. And right now, even as headline inflation has eased from its painful peaks, core measures are proving far more stubborn.

Inflation may come down on paper, but when your weekly shop still feels more expensive than last year, the statistics don’t always match the lived experience.

I think that disconnect is key. Official figures average everything out, but your own “personal inflation rate” depends heavily on what you buy and where you live. Rent, energy bills, childcare – these hit harder for some than others.

Recent History: From Double-Digit Peaks to Today’s Reality

Let’s step back for a moment. Not so long ago, inflation surged to levels most of us had never seen in our adult lives. The peak of 11.1% in late 2022 still lingers in memory – that was when energy shocks, supply-chain chaos and post-pandemic demand collided. Since then, the trend has broadly been downward, though not without bumps.

2024 brought its own twists, including a temporary plateau around 3.8% over the summer months. Then came the Autumn Budget effects, which fed through to employer costs and, indirectly, to prices. November’s drop felt like a genuine step forward, but December could remind us that progress is rarely linear.

  • Post-Covid low: inflation hovered near 0.2% in 2020 – too low for economic health.
  • Rapid climb: from late 2021 onward, prices accelerated sharply.
  • Peak pain: 11.1% in October 2022 – a modern high.
  • Gradual retreat: trending lower through 2024 and into 2025, with occasional stalls.

Looking at that trajectory, it’s clear we’re in a different phase now. But “different” doesn’t mean “solved.” And that’s where December’s data becomes so telling.

What Analysts Are Expecting – and Why the Range Matters

Most forecasts I’ve seen point to a rise – perhaps to 3.4% or 3.5% for the year to December. That would mark a reversal from November’s dip. Some economists have even floated slightly higher numbers if the price-collection date fell later in the month, capturing more of the pre-Christmas markup.

One factor that could swing the outcome is the exact timing of the data snapshot. Early December collections might show a smaller increase; a mid-month pull could catch more festive pricing pressure. Either way, the consensus leans toward an uptick rather than continued cooling.

In my view, this isn’t necessarily alarming – it’s more a reminder that inflation doesn’t descend in a neat straight line. External shocks, seasonal patterns and policy changes all play their part. Still, any rise will renew focus on when we might finally see that 2% target again.

The Longer-Term Outlook: When Might Inflation Return to Target?

Looking ahead, projections are cautiously optimistic. The Bank of England has pencilled in a drop toward 3% early in 2026, with further easing later in the year. By the final quarter, some see inflation averaging around 2.5%, and possibly dipping below target in 2027.

That’s encouraging, but timelines keep shifting. What seemed like a swift return a couple of years ago now looks more drawn-out. Persistent services inflation, wage pressures and global uncertainties all weigh on the path.

Perhaps the most interesting aspect is how the Bank balances inflation control with growth concerns. Rates have already started coming down, even as inflation sits well above target. That unusual dynamic reflects an economy that’s cooling faster than prices in some areas.

How Inflation Hits Your Wallet – Real-World Impacts

Let’s get practical. When inflation climbs, even modestly, it chips away at real incomes. Wages might rise, but if prices outpace them, you’re effectively poorer. Savings lose value in real terms unless they earn enough interest to offset the rise.

For savers especially, the past few years have been tough. Holding cash long-term has meant watching purchasing power shrink. And while rates have improved recently, any further drop in base rate could pull savings yields down again – just as inflation refuses to disappear entirely.

  1. Check your savings rate – if it’s below inflation, your money is losing value in real terms.
  2. Consider diversifying – some exposure to investments can help protect against erosion.
  3. Review fixed costs – locking in mortgage or energy deals can shield against spikes.
  4. Track your own basket – calculate your personal inflation rate for a clearer picture.

I’ve found that small, consistent habits like these make a surprising difference over time. They don’t eliminate inflation’s bite, but they blunt it.

What This Means for Interest Rates and Borrowing

The Bank of England’s decisions hinge heavily on these inflation prints. Higher-than-expected December numbers could make policymakers hesitate on further cuts – or at least slow the pace. Lower figures would strengthen the case for continued easing.

Either way, rates are likely heading lower over 2026, but the journey won’t be smooth. Mortgage holders renewing soon should keep a close eye on this release – it could influence the deals available in the coming months.

In my experience, the psychological impact is almost as big as the financial one. Uncertainty keeps people cautious, delaying big purchases or investments. That caution itself can slow the economy, feeding back into the inflation dynamic.

Wrapping Up: Tomorrow’s Number Won’t Tell the Whole Story

Whatever the ONS announces tomorrow, one release rarely changes the big picture overnight. December’s figure will add another piece to a complex puzzle, showing whether the recent downward trend held or stuttered. More importantly, it will remind us that controlling inflation is a marathon, not a sprint.

For now, the prudent approach is to stay informed, protect your purchasing power where possible, and avoid knee-jerk reactions to any single data point. Inflation has dominated headlines for years – but the quiet decisions we make around money management often matter more in the long run.

I’ll be watching the release closely tomorrow, as I suspect many of you will too. Here’s hoping the number brings a bit more reassurance than alarm. In the meantime, take a moment to check your own budget – sometimes the most powerful response to inflation starts right there at the kitchen table.
