Policies designed to avoid economic downturns at all costs can lead to significant long-term risks. Capital and labor become trapped in inefficient companies that would otherwise fail, hindering productivity growth and creating a less dynamic economy.

Slime mold spreads out when resources are abundant but recongeals when scarce. Similarly, when capital is cheap, talent spreads into startups. Businesses profiting from this boom (e.g., co-working spaces) face massive downside operating leverage when capital tightens and the "slime mold" of talent retracts to safer jobs.

Japan is trapped in a low-growth cycle because decades of artificially low interest rates have created "zombie companies." These inefficient firms survive by servicing cheap debt but don't innovate, locking up talent and capital that should be fueling new ventures. True economic revival requires the creative destruction of letting these companies fail.

Ajay Banga explains that when interest rates are low for extended periods, capital receives outsized returns while labor's share of economic outcomes shrinks. This dynamic is a primary driver of rising inequality, as those who already have money are able to make even more.

The Federal Reserve’s traditional economic lever—lowering interest rates to spur hiring—is becoming obsolete. In the AI era, companies will use cheaper capital to invest in productivity-boosting AI agents and robots rather than increasing human headcount. This fundamentally breaks the long-standing link between monetary policy and employment.

Contrary to popular belief, low interest rates historically indicate a weak economy with high demand for safety and liquidity. Conversely, rising rates signal expectations of economic growth or inflation, as capital seeks better returns in the real economy rather than safe government bonds.

Japan's economy is stagnant because cheap debt has kept inefficient 'zombie companies' alive, preventing capital and talent from flowing to innovative new ventures. The only long-term solution is a painful, decade-long process of raising interest rates to force these companies to fail, fostering true growth.

Unlike past recessions where defaults spike and then recede, the current high-rate environment will keep financially weak 'zombie' companies struggling for longer. This leads to a sustained, elevated default rate rather than a sharp, temporary peak, as these firms lack the cash flow to grow or refinance.

The prolonged period of near-zero interest rates encouraged businesses, especially in private equity, to take on massive leverage. These companies, structured for cheap debt, are now struggling to survive in a normalized rate environment, creating a significant systemic risk.
