The global economy may be heading into a dangerous new phase—one that economists haven’t seriously feared in decades. According to a stark new warning from Bank of America, the world is now entering what they call a period of “mild stagflation”—a toxic combination of slowing growth and rising inflation driven largely by an energy shock tied to the Iran conflict.

And the headline prediction is enough to shake markets: oil prices could stay near $100 per barrel for the entire year—even if the war ends soon.

This isn’t just another routine forecast revision. It’s a complete rethink of the global economic outlook.

Bank of America economists have essentially “ripped up” their previous projections, warning that the ongoing disruption in energy markets has fundamentally changed the trajectory of growth and inflation. The war in Iran has already triggered massive supply chain instability, particularly in oil, gas, and fertilizers—three pillars of the global economy.

At the center of the crisis lies the Strait of Hormuz, a narrow but vital shipping route through which about 20% of the world’s oil supply passes. Disruptions here have sent shockwaves through global markets, pushing crude prices above $100 and raising fears of prolonged shortages.

But what makes this situation especially dangerous isn’t just high oil prices—it’s the combination of factors happening at once.

Bank of America now expects global growth to slow while inflation accelerates, a rare and troubling economic mix. Their projections suggest global growth could drop while inflation rises significantly, reflecting what analysts describe as a broad “energy shock,” not just an oil issue.

In simple terms: economies may grow slower, while everything—from fuel to food—gets more expensive.

And we’re already seeing early signs.

Oil has surged dramatically in recent weeks, with prices jumping more than 50% during March alone amid escalating conflict. Meanwhile, global stock markets have stumbled as investors brace for inflation and uncertainty.

The implications stretch far beyond Wall Street.

Higher oil prices feed directly into transportation costs, manufacturing expenses, and even agriculture—since fertilizers depend heavily on energy inputs. That means rising food prices could follow closely behind, hitting developing countries particularly hard.

For countries like Pakistan, India, and many European nations that rely on imported energy, the situation could quickly become painful. Currency pressures, rising fuel costs, and inflation could combine into a perfect economic storm.

Even central banks are caught in a bind.

Normally, slowing growth would push policymakers to cut interest rates. But rising inflation limits their ability to do so. This creates a policy dilemma that could prolong economic weakness.

In fact, some analysts warn that if oil remains elevated for too long, it could tip parts of the global economy into recession territory.

Yet what’s most striking about Bank of America’s warning is its long-term implication.

Even if the conflict de-escalates within weeks, the damage may already be done. Supply chains have been disrupted, markets destabilized, and expectations reset. Oil prices, they argue, may not fall back to previous levels anytime soon.

This signals a broader shift: the world is no longer just dealing with temporary shocks—it’s entering a more volatile, uncertain energy era.

And in that era, stability may become the exception—not the norm.
