🧾 What "national debt" really means

This is not a credit card bill that a country has to pay tomorrow. It is the total amount a government has borrowed over time to finance expenses that exceed its tax revenues.

In practice, it works through bonds. Governments issue debt, investors buy it, and in return, they earn interest. This includes banks, funds, pension systems, and often the country's own central bank.

The key point is not just the size, but who owns it and how manageable it is. Strong economies can support a large debt because there is a constant demand for their bonds and confidence in their system.

So the number itself may seem frightening, but the real question is always the same: can they continue refinancing it and meeting payments without breaking trust?
