Stagflation usually results from a combination of supply-side disruptions, policy mistakes, and structural inefficiencies. Some of the major causes include:
Supply-Side Shocks
Sudden increases in the cost of key inputs—such as oil, food, or raw materials—can trigger cost-push inflation even when demand is low. The 1970s oil embargo is a classic example.
Poor Economic Policies
Excessive money printing, rigid labour policies, or heavy regulation can suppress productivity while fuelling inflation.
Cost-Push Inflation
When wages, energy, or import costs rise significantly, companies pass these costs onto consumers, pushing prices higher even during economic stagnation.
Structural Weaknesses
Low productivity, inefficient industries, or limited innovation can slow growth and make the economy more vulnerable to external shocks.
Exchange Rate or Currency Crises
A sharp depreciation raises import costs, contributing to inflation while reducing domestic purchasing power.
