What are the implications of rising global debt levels?

Rising global debt is not automatically a sign of an impending crisis. The implications depend on who owes the money, who holds it, the currency and terms of repayment, and whether borrowing is supporting productive activity or simply covering ongoing costs.

For governments, higher debt can mean more public funds go toward debt-servicing costs, especially when interest rates rise or existing loans need refinancing. That can narrow the room for future spending on services, infrastructure, or emergency support. It may also push up government borrowing costs if lenders begin to doubt a borrower’s ability to repay.

Debt can be useful: borrowing to build infrastructure, fund education, or respond to a severe downturn may support future growth. The concern is when debt grows faster than the economy’s ability to manage it. Companies and households face a similar trade-off: loans can finance investment or major purchases, but heavy repayments leave them more exposed to job losses, falling revenues, or higher rates.

The risks are uneven. Countries that borrow in their own currency and have reliable institutions may have more options than those relying on foreign-currency debt. And a large share of debt held by domestic investors can create different pressures from debt owed abroad. If many borrowers retrench at once, weaker spending can drag on economic growth and put financial stability risks on the table.

So the headline debt total matters, but it is only a starting point. Debt levels are best judged alongside interest costs, income and growth, repayment schedules, and what the borrowed money is used for.
