Stagflation Explained: What It Means for Your Money

Most economic downturns come in one flavour at a time. In a recession, demand collapses, jobs disappear, and prices tend to fall. During an inflationary boom, the economy runs hot, wages climb, and the cost of living creeps up. Each is painful, but each has a relatively clear fix.

Stagflation is what happens when you get the worst of both at once. Prices keep rising while the economy stalls, unemployment ticks up, and growth flatlines. It is the economic equivalent of being stuck in traffic with the fuel gauge on empty.

If you have been watching the headlines about tariffs, supply chain disruption, and escalating conflict in the Middle East, you might be wondering whether we are heading back there. Here is what stagflation actually is, why it matters, and what you can do about it.

What is stagflation?

Stagflation is a combination of three things happening at the same time:

1. High inflation - the cost of goods and services keeps rising.
2. Stagnant economic growth - GDP is flat or shrinking.
3. Rising unemployment - businesses stop hiring or start cutting.

In normal economic theory, inflation and unemployment are supposed to move in opposite directions. When the economy booms, prices rise but jobs are plentiful. When the economy contracts, demand falls and prices stabilise. Stagflation breaks that relationship. You get rising prices without the economic growth that usually causes them.

The term was coined in the 1960s by British politician Iain Macleod, but it became a household word in the 1970s when the UK and US both lived through it for nearly a decade.

The 1970s playbook

The textbook case of stagflation started with the 1973 oil crisis. OPEC imposed an embargo on Western nations, and the price of oil quadrupled almost overnight. Because oil feeds into the cost of virtually everything - transport, manufacturing, heating, food production - inflation surged across the developed world.

At the same time, economic growth slowed sharply. Businesses could not absorb the higher costs. Consumers pulled back spending. Unemployment rose.

In the UK, inflation hit 25% in 1975. Interest rates climbed into the mid-teens. The economy bounced between recession and weak recovery for years. It took aggressive rate hikes under Paul Volcker in the US and a painful restructuring of the UK economy under Thatcher to finally break the cycle - at enormous social cost.

The lesson from that era: stagflation is not a short-term blip. Once it takes hold, it is genuinely difficult to reverse, because the usual policy tools work against each other.

Why stagflation could return

The conditions that created the 1970s mess are lining up again:

Trade wars and tariffs

Tariffs are a tax on imports that gets passed directly to consumers. When the cost of imported goods rises, businesses either absorb the hit (squeezing margins and slowing growth) or pass it on (pushing up prices). Either way, the economy gets worse. Broad-based tariffs on goods from major trading partners are textbook supply-side inflation - prices rise not because demand is strong, but because supply costs more.

The Iran conflict

Military escalation in the Middle East threatens oil supply routes and energy markets. Even the prospect of disruption sends prices higher. If the conflict widens or oil infrastructure is targeted, the parallels with 1973 become uncomfortably direct. Energy price shocks feed through to every corner of the economy, from food transport to manufacturing to heating bills.

As we wrote when tensions first escalated, geopolitical crises are not a reason to panic-sell your portfolio. But they can create real economic drag, especially when they coincide with other pressures.

Supply chain fragility

The pandemic exposed how brittle global supply chains had become. Reshoring, friend-shoring, and strategic decoupling from China all add friction and cost. These shifts are probably necessary for long-term resilience, but in the short term they push prices up without generating proportional growth.

Sticky inflation from the pandemic era

Central banks printed enormous amounts of money during Covid. Much of that liquidity is still working through the system. Inflation has come down from its peak, but getting it back to target has proved stubbornly difficult. If a new supply shock lands on top of already-elevated prices, the result could be persistent inflation at a time when the economy is already losing momentum.

Why central banks struggle with it

This is the core problem. Central banks have one main lever: interest rates.

• Raise rates to fight inflation, and you crush an already weak economy. Businesses that are struggling to grow now face higher borrowing costs. Unemployment gets worse.
• Cut rates to stimulate growth, and you pour fuel on inflation. The cost of living accelerates while wages lag behind.

During a normal recession, rate cuts help. During normal inflation, rate hikes help. Stagflation makes both options painful. Policymakers end up choosing which problem to make worse, and there is no clean exit.

That is why the 1970s dragged on for so long. Nobody wanted to accept the short-term pain required to break the cycle until there was no other choice.

What it means for your money

Stagflation hits from multiple angles at once:

• Savings lose value. If inflation is running at 6% and your savings account pays 3%, you are losing purchasing power every month.
• Wages stagnate. Companies under pressure do not hand out pay rises. Your income flatlines while your costs climb.
• Investments struggle. Equities often underperform during stagflation because corporate earnings get squeezed by rising input costs and falling demand. Bonds suffer too, because inflation erodes their fixed returns.
• Property becomes unpredictable. Higher interest rates push up mortgage costs, but inflation can support nominal house prices. The result is a market that feels expensive from every angle.
• Debt gets more expensive. If you are carrying variable-rate debt, your repayments rise even as your income stalls.

The usual playbook of "earn more, invest the difference" gets harder to execute when both sides of that equation are under pressure.

How to protect yourself

There is no perfect hedge against stagflation, but there are sensible steps:

Reduce personal debt

Variable-rate debt is the biggest vulnerability in a stagflationary environment. If you are carrying credit card balances or a large variable mortgage, reducing that exposure should be a priority. Fixed-rate debt is less urgent, because inflation actually erodes the real value of what you owe.

Build a spending buffer

An emergency fund matters more than ever when the job market is soft and costs are rising. Three to six months of expenses in an easy-access account gives you options that a fully invested portfolio does not.

Stay diversified

A globally diversified portfolio tends to hold up better than a concentrated one. International diversification reduces your exposure to any single economy's stagflationary mess. Commodities and inflation-linked bonds (like UK index-linked gilts) can provide some offset when conventional equities and bonds both struggle.

Do not abandon equities

Equities underperform during the worst of stagflation, but they recover. The companies that survive - those with pricing power, low debt, and essential products - tend to come out stronger. If you are not sure what "pricing power" means in practice, value investing is a good place to start. And staying invested through the noise has historically beaten trying to time the exit and re-entry.

Keep investing consistently

If you have a monthly investment habit, keep it running. Buying into a struggling market means your regular contributions pick up more units at lower prices. When the recovery arrives, those units do the heavy lifting.

Frequently asked questions

How is stagflation different from a normal recession?

In a normal recession, demand falls, unemployment rises, and prices tend to drop or stabilise. Central banks can cut interest rates to stimulate borrowing and spending, which eventually restarts growth. Stagflation adds persistent inflation on top of the recession, which means rate cuts would make the inflation problem worse. That leaves policymakers stuck, and it leaves consumers dealing with rising costs and falling income at the same time.

Has the UK experienced stagflation before?

Yes. The UK went through a severe stagflationary period in the 1970s. Inflation peaked at around 25% in 1975, unemployment rose sharply, and economic growth was weak or negative for extended periods. It took years of painful adjustment, including aggressive interest rate policy and structural economic reform, to bring the situation under control.

Are tariffs enough to cause stagflation on their own?

Tariffs alone probably will not trigger full stagflation, but they pile on. They raise input costs for businesses and consumer prices for households while slowing trade and economic growth. Stack tariffs on top of an energy price shock from a Middle East conflict and you get the kind of compounding supply-side pressure that tipped the 1970s over the edge.

What investments perform best during stagflation?

No asset class thrives in stagflation, but some hold up better than others. Commodities (especially energy and gold) tend to rise with inflation. Inflation-linked bonds protect against purchasing power erosion. Companies with strong pricing power - those that can pass cost increases to customers without losing demand - tend to outperform. Cash loses value in real terms but provides flexibility. The worst performers are typically long-duration bonds and growth stocks with distant earnings.

Should I move my portfolio to cash if stagflation hits?

Moving entirely to cash means accepting a guaranteed loss of purchasing power if inflation is running above your savings rate. While cash provides stability and flexibility, it is not a solution to stagflation. A better approach is to stay diversified, keep investing regularly, and ensure you have enough liquidity to cover expenses without being forced to sell investments at a bad time.
