What Stagflation Actually Means and Why It's Back on the Table

Seven weeks into the Iran conflict and the global economy is dealing with something economists haven't seriously worried about since the 1970s: stagflation. That's the ugly combination of rising prices and stalling growth happening at the same time. And according to business surveys coming out this week, it's not just theoretical anymore.

The first round of purchasing manager indexes after the conflict started showed weakness in both directions—growth slowing down while inflation pressures built up. The April numbers drop Thursday, and if the pattern holds, we're looking at a structural problem that can't be fixed with a quick policy response.

Chris Williamson, chief business economist at S&P Global, already used the word "stagflation" when summarizing March's global PMI data. That's not a term people throw around casually.

Normal recessions are painful but predictable. Demand drops, prices cool off, central banks cut rates, and eventually things recover. Stagflation breaks that playbook because the tools that fix one problem make the other worse.

If you cut rates to stimulate growth, you risk letting inflation run hotter. If you raise rates to control prices, you choke off what little growth is left. Central banks hate this situation because there's no clean solution.

The 1970s version came from oil shocks tied to Middle East conflicts and OPEC supply decisions. This one's coming from the same place—energy prices spiking because of war-driven uncertainty in a region that controls a huge chunk of global oil supply.

IMF Managing Director Kristalina Georgieva laid it out pretty bluntly: "Even if the war ends tomorrow, it would take quite some time for the recovery to kick in. The impact is already baked in."

Thursday brings preliminary PMI readings from Australia, the US, Germany, France, the UK, and the euro zone. Bloomberg's consensus forecasts show broad deterioration across Europe, while US indicators are expected to stay roughly flat.

Those are composite measures of business activity—manufacturing, services, new orders, employment, prices paid. A reading above 50 signals expansion, below 50 signals contraction. What matters more than the headline number is the internal breakdown, especially the gap between output and input prices.

If businesses are seeing input costs rise (oil, freight, raw materials) while output demand is falling, that's the stagflation dynamic in real time. They can't raise prices enough to cover costs without killing demand further, so margins get squeezed and layoffs follow.

Canada's inflation report for March is expected to jump from 1.8% to 2.6%, driven almost entirely by gas prices. UK inflation is forecast to hit 3.3% from 3%. South Africa's first post-conflict reading is expected at 3.1%, up from 3%.

Meanwhile, US retail sales for March are projected to show a big headline jump, but strip out gasoline and autos and the picture looks weaker. People spent more on gas because they had to, which means they spent less on everything else. That's not a sign of healthy demand.

ECB chief economist Philip Lane said his team will look at survey data "in context" when they set rates later this month, which is central banker speak for "we have no idea what to do yet."

The problem is that survey respondents are looking at the same uncertainty everyone else is. Nobody knows if the current ceasefire holds, if oil prices stabilize, if supply chains adjust, or if this turns into a longer disruption.

If you're not familiar with how geopolitical shocks actually move markets, the short version is that uncertainty itself does more damage than the event. Businesses freeze hiring and investment plans. Traders widen bid-ask spreads. Consumers delay big purchases. That behavior becomes self-reinforcing pretty quickly.

Kevin Warsh's Fed chair confirmation hearing happens Tuesday, and it's going to be awkward. He's supposed to explain how he'll deliver lower rates like President Trump wants while also controlling inflation during an oil shock. Those goals contradict each other, and markets know it.

Turkey's central bank meets Wednesday and might actually raise rates despite already sitting at 37%, because energy-driven inflation is getting out of hand. Three of eleven economists surveyed expect a 300-basis-point hike. That's how serious the pressure is in some places.

Indonesia and the Philippines are both leaning toward tightening or holding steady to defend their currencies against imported inflation. Russia's deciding Friday whether to keep easing or pause. Nobody's got a clear path forward.

Here's the part that doesn't show up in the data until it's too late: expectations.

If businesses and consumers start expecting inflation to stay elevated, they change behavior in ways that make it self-fulfilling. Workers demand bigger raises. Companies raise prices preemptively. Contracts get indexed to inflation.

That's what happened in the 1970s, and it took years of brutal monetary policy to break. Paul Volcker pushed the Fed funds rate above 20% to kill inflation expectations, which also killed growth and employment for a while.

The University of Michigan's consumer sentiment index for April already hit a record low in the preliminary reading. Final numbers drop Friday. If people feel like their purchasing power is eroding and their job security is shaky at the same time, they pull back on spending, which feeds the growth slowdown.

The gap between knowing this intellectually and actually adjusting your behavior is what trips up most traders during volatile periods like this. You see the setup developing, but you hesitate or overcomplicate the response.

Forget trying to predict where this goes. The setup right now is uncertainty with downside skew.

Watch the PMI internals on Thursday, specifically:-Input vs. output price indices: widening gap = margin squeeze-New orders vs. backlogs: falling orders with rising backlogs = demand problem-Employment subindexes: dropping employment signals defensive positioning

Watch oil price action around geopolitical headlines. If crude can't hold gains on ceasefire news, that's telling you the market doesn't believe the stabilization story.

Watch currency pairs, especially EM currencies against the dollar. Weakness there signals capital flight and imported inflation pressure, which forces central banks into defensive rate hikes that hurt growth.

Watch credit spreads in high-yield and investment-grade bonds. Widening spreads mean funding conditions are tightening even if central banks haven't moved yet.

The specific levels depend on your market and timeframe, but the structure is what matters. If you're seeing distribution patterns (lower highs, declining volume on rallies, rejection wicks at resistance), that's the market telling you it doesn't trust the current price level.

Georgieva's line about "high and permanent uncertainty" is the key takeaway. Even if the immediate crisis resolves, the structural conditions that allowed it—energy dependency, supply chain fragility, geopolitical instability—don't disappear.

That means elevated baseline risk, which means higher volatility, which means wider ranges and lower conviction. Markets don't trend cleanly in that environment. They chop, they fake, they reverse on headlines.

For position traders, that's frustrating because setups don't play out the way they do in clearer trending periods. For swing traders, it's opportunity if you're willing to work smaller timeframes and tighter risk management.

The stagflation scenario is still a risk, not a certainty. But the data coming this week will show whether that risk is increasing or stabilizing. Either way, the playbook from the last two years—buy dips, fade weakness, trust the trend—doesn't work the same way when growth and inflation are pulling in opposite directions.
