1. The fundamentals — why this matters

The debt trap is one of the most subtle and dangerous risks in stock investing, where low direct interest rate sensitivity conceals a deeper structural vulnerability.
In a low interest rate environment, investors tend to ignore a company's debt level, since the direct cost of the debt is low. This passivity is however dangerous, because the debt trap does not manifest itself in the form of high interest costs, but as lost flexibility and an increased sensitivity to unexpected events. When interest rates rise or when a business cycle downturn occurs, the company suddenly becomes very vulnerable, not only because of the increased interest costs, but because of the limited possibility of adapting.
The debt trap is a strategic trap that ties up capital and reduces a company's ability to act proactively in the market.
The underlying mechanism behind the debt trap is the so-called 'operating leverage'. A company with a high debt-to-equity ratio will see its earnings per share of stock (EPS) fluctuate sharply in relation to changes in operating profit. Even a small decline in revenue can be amplified into a dramatic reduction in profit, leading to a surprising and often ominous decline in the share price.
This effect is particularly dangerous in cyclical industries where revenue naturally varies, and the debt trap then becomes a time bomb that can detonate when the business cycle turns.
