Stagflation Risk Returns: What the US–Iran Conflict Means for Markets

The conflict between the United States and Iran is escalating, with no clear path to de-escalation. 

Iran has proven to be a difficult opponent. Not because of military strength alone, but because of something more powerful. 

Its real leverage lies in the economy, the Strait of Hormuz, energy supply, and inflation

And markets are starting to feel it. 

Just months ago, the outlook was clear. 

Inflation was cooling. 
The labor market was stable. 
The Fed was preparing to cut rates. 

soft landing looked achievable. 

That narrative is now breaking down. 

Since tensions escalated in late February, energy prices have surged, pushing inflation risks back to the forefront. At the same time, US unemployment is showing early signs of rising

This combination is dangerous. 

It points toward a scenario markets fear most: 

stagflation

Stagflation is one of the most painful phases of the economic cycle. 

It combines: 

  • high inflation  
  • low or slowing growth  
  • rising unemployment  

It limits policy options and compresses asset performance. 

And importantly, it is not new.  

The United States has faced stagflation before. 

In the 1970s, two major stagflation periods reshaped the global economy: 

  • 1973–1974  
  • 1976–1980  

During these periods, the relationship between growth and inflation broke down. 

GDP slowed while inflation accelerated. 

That divergence defines stagflation.

Two major forces drove it. 

Money supply expanded rapidly. 

The US government ran large deficits to fund: 

  • social programs  
  • the Vietnam War  

This created persistent inflation pressure. 

A modern parallel is clear. 

The massive liquidity injection during the 2020 pandemic continues to shape today’s inflation dynamics.

The 1973 Middle East war triggered a surge in energy prices. 

  • WTI crude rose from $3.56 to $39.50 by 1980  
  • More than a 10x increase  

Energy was the catalyst that pushed inflation higher.

There are clear parallels: 

  • Post-pandemic excess liquidity  
  • Rising energy prices  
  • Renewed geopolitical tension  

But there are also key differences. 

In the 1970s: 

  • The dollar weakened  
  • Confidence in US assets declined  

Today: 

  • The dollar is strengthening, not weakening  
  • Capital is still flowing into US assets  

This changes how markets react.

Stagflation is one of the most challenging environments for investors. 

According to the Merrill Lynch Investment Clock, few assets perform well. In many cases, cash becomes the safest position

In the 1970s, equities went through two distinct phases. 

  • S&P 500 dropped nearly 50%  
  • P/E ratios compressed from ~20x to below 7x  
  • Liquidity tightened  
  • Sentiment deteriorated

Once pessimism was fully priced in: 

  • earnings improved  
  • confidence returned  
  • equities recovered  

This shows a key insight: 

Markets bottom before the economy recovers.

Historically, gold performs well during stagflation. 

Rising inflation supports commodity prices. 

But today is different. 

  • Higher interest rate expectations  
  • A stronger dollar  

Both are pulling capital away from gold. 

This explains why gold can fall even during inflation fears

Stagflation is not the end of the cycle. 

It is part of it. 

Even in stagflation: 

  • strong companies survive  
  • weak, hype-driven assets fade  

Liquidity may tighten, but fundamentals still matter

During the 1970s: 

  • energy sector weight in the S&P 500 rose from 20% to 30%  

Higher oil prices directly boosted profitability. 

If the current conflict persists, energy could once again outperform. 

Inflation increases the cost of living. 

As a result: 

  • discretionary spending declines  
  • consumer sectors underperform  

Not all “defensive” sectors are safe. 

The market is now entering a more complex phase. 

  • Inflation is returning  
  • Growth is slowing  
  • Policy flexibility is shrinking  

This is not a clean macro environment. 

It is a transition phase

Volatility will remain elevated. 

Narratives will shift quickly. 

And positioning will matter more than ever.  

Stagflation does not destroy markets. 

But it reshapes them. 

For traders and investors, the goal is not to predict the next headline. 

It is to understand how macro forces translate into asset behavior

Because in environments like this: 

The biggest risk is not volatility. 
It is being positioned for the wrong cycle.
