Steve Keen argues that U.S. stocks and the broader economy are being propped up by credit growth, not underlying strength, and that rising debt levels make the system fragile again. He says the real issue is “credit stagnation,” not secular stagnation, and warns that the next debt crisis will likely hit countries like Canada, Australia, and South Korea before the U.S. fully resets.

Steve Keen’s core thesis is that the U.S. economy and stock market are being supported by credit expansion, but that this support is inherently unstable because private debt has risen back toward levels that previously caused crisis. He frames the current environment as a temporary recovery driven by borrowing, not a durable expansion, and says the market and economy will “run out of air” once debt reaches its ceiling again. In his view, the stock market’s repeated highs sit on top of a fragile credit structure rather than real balance-sheet repair. He argues that the key variable is the annual change in private debt, which he says feeds directly into money supply and aggregate demand. He claims U.S. private debt fell sharply after the financial crisis, then borrowing resumed at roughly 6–7% of GDP, creating a modest boost to growth. …
Tactically, the setup is fragile if borrowing slows or rates keep tightening, because Keen thinks the market is sitting on a credit-dependent air pocket. The immediate risk is that a credit rollover would undermine the current stock rally faster than investors expect.
Over the next few months, the base case in Keen’s framework is a gradual loss of momentum as private debt growth flattens and the Fed’s tightening bites. Confirmation would come from weaker credit creation and softer demand; if borrowing reaccelerates, his warning is delayed rather than disproven.
Structurally, Keen is calling this a debt-regime problem: advanced economies need continuous credit expansion to sustain growth, which makes recurring crises endemic. If his model is right, durable policy success requires changing how private debt is managed, not just fine-tuning rates.
Rising private credit growth is the main reason the U.S. economy is currently holding up.
The speaker argues that growth in private borrowing is creating money and demand, offsetting weaker forces elsewhere in the economy.
The U.S. economy is fragile because private debt has risen back toward the peak level that previously caused a downturn.
He says debt burdens are again approaching extreme levels, which will cause credit to turn negative and remove support from the economy.
The next major debt crisis is likely to occur in Canada or Australia, with South Korea also at risk, within the next one to three years.
The speaker identifies these countries as 'zombies to be' that have relied on continued borrowing and says they are his standout nominations for the next crisis.
What will happen when the economy returns to its previous peak in private debt?
He says the economy will lose its air and fall again as debt rises back toward the old peak. In his view, higher rates and debt reduction would pull credit negative and remove the growth support.
What was the effect of credit growth on the U.S. economy after the financial crisis?
He says renewed borrowing has provided a modest boost to demand and helped recovery, alongside QE and rate cuts. But he emphasizes that the recovery remains fragile because private debt is still high and rising again.
Why does he reject the idea of secular stagnation?
He argues the slowdown is caused by weak credit growth and high debt, not by low birthrates or a lack of technological progress. He says the economy is stuck because aggregate demand is lower than it would be under stronger credit expansion.
