Stagflation is considered economically dangerous because it combines three problems that normally do not occur together: slow or negative economic growth, high inflation, and rising unemployment. Each of these issues is harmful on its own, but together they limit the tools policymakers can use and intensify the damage across the economy.

High inflation reduces purchasing power, making everyday goods and services more expensive for households. At the same time, weak growth and rising unemployment reduce incomes and job security. This combination puts severe pressure on consumers, leading to lower spending, weaker demand, and further economic slowdown. Businesses face higher input costs but weaker sales, which compresses profit margins and discourages investment.

Stagflation is especially difficult to manage because traditional policy responses conflict with each other. Raising interest rates can help control inflation, but it often worsens unemployment and slows growth further. Cutting rates or increasing government spending may support growth, but risks pushing inflation even higher. This policy dilemma can prolong economic instability.

Financial markets also suffer during stagflation. Equities struggle due to weaker earnings, bonds lose value as inflation rises, and currencies can become volatile. Over time, prolonged stagflation erodes confidence in economic institutions and policy credibility. Because it damages living standards, investment, and stability all at once, stagflation is one of the most challenging and dangerous economic environments to navigate.
