Everyone expected a rate cut this month, but the escalating war in Iran flipped the script. The Bank of England held steady at 3.75%, citing soaring energy costs and stubborn inflation. What happens next to your finances could be more painful than anticipated...

Financial market analysis from 19/03/2026. Market conditions may have changed since publication.

Have you ever felt like the economy is finally giving you a break, only for something completely out of left field to yank the rug right back? That’s exactly how many of us felt this week when the Bank of England announced its latest interest rate decision. Just a few short weeks ago, the chatter was all about cuts—maybe even a meaningful one right now. Then the war in the Middle East escalated dramatically, and suddenly those hopes evaporated almost overnight.

It’s frustrating, isn’t it? One minute you’re calculating how much lower your mortgage payments could be, the next you’re staring at forecasts that suggest things might stay expensive—or get worse—for longer than anyone wanted. I’ve been following these cycles for years, and this feels like one of those moments where global events remind us just how interconnected everything really is.

Why the Bank of England Chose to Hold Steady

The decision to keep the base rate at 3.75% wasn’t exactly a shock by the time the announcement came. Markets had already priced it in pretty heavily after oil and gas prices started climbing sharply. But let’s be honest: a month ago, hardly anyone saw this coming. The Monetary Policy Committee had been signaling more easing ahead, and the vote last time around was razor-close. This time? Unanimous. That tells you something about how seriously they’re taking the new risks.

At the heart of it all is energy. When conflict disrupts major producers and shipping routes, prices don’t just nudge up—they spike. And those spikes feed straight into inflation. The committee made it clear they’re watching closely, not just for immediate jumps but for any signs that higher costs start embedding themselves into wages, services, and everyday pricing. It’s the kind of caution that makes perfect sense when memories of recent energy shocks are still fresh.

The Energy Price Shock Explained

Let’s break down what’s actually happening with energy. Oil prices have surged to levels we haven’t seen consistently since the early days of the last major crisis. Gas markets are feeling similar pressure. Even if the conflict were to wind down quickly—which nobody is betting on right now—rebuilding supply chains and restocking takes time. That lag keeps prices elevated, and elevated prices mean higher bills for everyone.

Households are somewhat shielded for now thanks to the price cap mechanism, but that protection only lasts so long. Come summer, many people could be looking at significantly higher energy costs unless wholesale markets calm down fast. Businesses face the same issue, often with less buffer, which means they pass costs on wherever they can. It’s a classic supply-side shock, and central banks hate those because they’re harder to control with interest rates alone.

Even a short disruption can leave lasting scars on supply networks, keeping prices higher for months.

– Economic analyst perspective

In plain terms, the Bank isn’t ignoring softer domestic data like slowing wage growth or steady unemployment. Those would normally scream “cut now.” But the upside risks to inflation from energy are simply too big to ignore. Better to wait and see than to ease too soon and have to reverse course later—that would hurt credibility and probably make things worse.

What This Means for Your Mortgage and Borrowing

Perhaps the most immediate sting for many readers is what this does to mortgage rates. Fixed deals were already edging higher even before the announcement as markets adjusted. Lenders look ahead, and when they see the central bank pausing its cutting cycle, they price in higher funding costs. The result? Deals that looked attractive a few weeks ago now carry a noticeably bigger price tag.

If you’re on a tracker or variable mortgage, the base rate staying put means your payments don’t fall—yet. And if you’re remortgaging soon, you might be locking in at rates that feel painfully close to where they were before the easing started. I’ve spoken to friends in exactly this position, and the mood is one of quiet resignation mixed with a bit of hope that things stabilize quickly.

  • Two-year fixed rates have climbed noticeably in recent weeks.
  • Five-year fixes are following a similar path, though slightly less aggressively.
  • Anyone coming off a low fixed deal from a couple of years ago faces a real jump regardless.
  • Savers might see marginally better returns on cash ISAs and bonds, but it’s cold comfort when borrowing costs stay high.

The frustrating part is that this isn’t driven by domestic overheating—it’s imported from halfway around the world. Yet we still pay the price at home. That’s the reality of a globally connected economy.

Inflation Outlook: Back Above Target?

Before all this, the path looked encouraging. Inflation had been trending down, even dipping below target briefly in some measures. Forecasts pointed to a return to 2% fairly comfortably this year. Now? The picture is murkier. Depending on how long energy prices stay high, we could see headline inflation pushing toward 3.5% or higher in the coming quarters.

That’s not catastrophic, but it’s enough to make policymakers nervous. They don’t want expectations to unanchor. Once people start believing inflation will stay high, behavior changes—wage demands rise, businesses hike prices preemptively—and suddenly you’re fighting a much harder battle. The committee seems determined to avoid that trap.

Interestingly, core measures (stripping out volatile food and energy) are still softening. That gives some hope that the shock might prove temporary. But hope isn’t policy. They need evidence, and right now the evidence points to caution.

Stagflation Fears: Real or Overblown?

One word keeps popping up in conversations: stagflation. Higher prices and sluggish growth. It’s the worst of both worlds, and we’ve seen glimpses of it before. Growth has already been disappointing, with some quarters barely moving. Add an energy squeeze, and you risk tipping into something uglier.

I’m not convinced we’re heading straight there yet. The labor market still has some slack, fiscal policy is tightening, and monetary settings remain restrictive. Those factors should help cap second-round effects. But if energy stays elevated for many months, the risk grows. Households feel squeezed, spending drops, businesses hesitate—and the whole thing feeds on itself.

The economy is caught between cooling demand and a fresh supply shock—classic conditions for stagflation worries.

– Market commentary

Perhaps the most sobering thought is how little control domestic policymakers have over the trigger. The conflict isn’t something the Bank can negotiate down. All they can do is respond to the fallout, and that response might mean higher-for-longer rates even if growth suffers.

Looking Ahead: When Might Rates Move Again?

Nobody has a crystal ball, but the consensus seems to be shifting toward “not soon.” Some forecasters have pushed back expected cuts by several months. Others are even floating the idea of a hike if things get really ugly. Personally, I think a hike would be an overreaction unless inflation expectations really break loose. The Bank has room to stay patient.

That said, patience cuts both ways. If the situation de-escalates faster than expected and energy prices fall back, the door to cuts reopens quickly. The committee has said they’re ready to act as needed to hit the target medium-term. Flexibility is the name of the game right now.

  1. Monitor energy futures closely—those curves tell us a lot about expected paths.
  2. Watch wage data and services inflation for signs of second-round effects.
  3. Keep an eye on global developments—the conflict’s trajectory matters more than almost anything domestic.
  4. Prepare for volatility in markets; sentiment can swing fast on headlines.
  5. Consider your own finances—locking in fixed rates or building cash buffers might make sense depending on your situation.

It’s a lot to take in, I know. Economic decisions that feel abstract on the news have a way of landing very concretely in our bank accounts and monthly budgets. The past few years have taught us that resilience matters, and sometimes that means accepting uncertainty while planning prudently.


So where does that leave us? Cautiously watching, I suppose. The Bank has chosen stability over optimism for now, and while that’s disappointing for borrowers, it’s understandable given the scale of the shock. Whether this turns into a prolonged headache or a temporary blip depends on events far beyond Threadneedle Street. In the meantime, staying informed and keeping options open feels like the smartest approach.

What are your thoughts? Has this decision changed how you’re viewing your own finances? Sometimes just hearing from others in the same boat helps put things in perspective. Either way, these are strange times—but we’ve navigated strange times before, and we’ll do it again.
