J.P. Morgan is warning that a major backdrop for the global economy is changing. In its view, the long period when demographic trends and other structural forces helped keep interest rates low is coming to an end, with smaller populations and wider fiscal deficits becoming more important drivers of markets.
The bank’s outlook points to the fading of the so-called demographic dividend that supported growth over the past four decades. As populations age and labor-force growth slows in many places, one of the key conditions that helped hold down borrowing costs may weaken. That shift could leave the world with a very different interest-rate environment than the one investors and policymakers became used to.
Debt is another major part of the picture. The IMF said in 2025 that total debt held by governments, households and companies worldwide had reached $251 trillion. With debt already so high, J.P. Morgan’s analysis suggests that persistent deficits and heavier borrowing needs could keep pressure on rates rather than allowing them to fall back to earlier lows.
Taken together, the bank’s message is that the global economy may be entering a period shaped less by abundant workers and subdued borrowing costs, and more by aging societies, large public deficits and elevated debt burdens. For businesses, consumers and governments, that could mean preparing for interest rates that stay higher than they were during much of the last 40 years.
