Debt and Economic Growth

“Debt levels worldwide are now roughly the same size as the entire global economy—yet many countries are still borrowing more. In one scenario, that borrowing funds new jobs and innovation. In another, it quietly sets the stage for the next crisis. Which path are we on?”

Japan’s government owes more than double what its economy produces in a year—yet markets aren’t panicking, and interest rates are still near zero. Meanwhile, some countries hit trouble with far less on the books. So the real puzzle isn’t “Is debt good or bad?” but “Under what conditions does it help or hurt?”

A key clue: what the borrowed money is *used for* and how the bill is ultimately paid. When funds go into things like transport networks, public health, or new technology, they can raise future incomes enough to cover today’s borrowing. When they prop up unproductive spending, the numbers swell without strengthening the engine underneath.
