Several internal and external factors can lead to margin compression. Common causes include:
1. Rising Input Costs
Increases in the price of raw materials, energy, logistics, or labour can directly squeeze margins if selling prices remain unchanged.
2. Competitive Pricing Pressure
Aggressive market competition often forces companies to reduce prices or offer discounts, compressing profit margins.
3. Regulatory or Tax Changes
New taxes, compliance costs, or pricing regulations can reduce profit margins, especially in regulated industries such as energy or banking.
4. Product Mix Shifts
If sales shift from high-margin products to lower-margin ones, overall profitability can fall even if revenue grows.
5. Currency Fluctuations
For exporters or global companies, an unfavourable exchange rate can lower profit margins in reporting currency terms.
6. Operational Inefficiencies
Poor cost control, supply chain disruptions, or underutilised capacity can contribute to shrinking margins.
