Asset Bubble

An asset bubble is a sustained divergence between the market price of an asset and its fundamental value — the present value of the income the asset is expected to generate — driven by self-reinforcing expectations of future price appreciation rather than by underlying cash flows. Bubbles are not merely irrational; they are rational within a coordination game. Each investor knows the price is too high, but each also knows that prices may rise further, and that exiting early means leaving gains to others. The bubble persists as long as the inflow of new buyers exceeds the outflow of the cautious. When the flow reverses, the collapse is nonlinear: the same positive feedback that inflated the bubble propagates the crash.\n\nBubbles are endemic to systems with abundant liquidity and leveraged speculation. The Federal Reserve's low-interest-rate policies after 2008 were designed to stimulate investment; they also inflated asset prices across equities, bonds, and real estate, creating a dependency that is politically difficult to unwind. The Minsky moment — the transition from speculative to Ponzi finance — is the tipping point where the system can no longer service its debts from income, and asset sales cascade. Bubbles are not accidents. They are the predictable byproduct of monetary systems that prioritize growth over stability and that socialize the losses of the wealthy while privatizing the gains.\n\n\n
