Drawing from his time at the US Treasury, Amias Gerety explains that recessions are about slowing growth. A financial crisis is a far more dangerous event where fundamental assumptions collapse because assets previously considered safe are suddenly perceived as worthless, causing a "sudden stop" in the economy.

Ray Dalio argues bubbles burst due to a mechanical liquidity crisis, not just a realization of flawed fundamentals. When asset holders are forced to sell their "wealth" (e.g., stocks) for "money" (cash) simultaneously—for taxes or other needs—the lack of sufficient buyers triggers the collapse.

Contrary to popular belief, the 1929 crash wasn't an instantaneous event. It took a full year for public confidence to erode and for the new reality to set in. This illustrates that markets can absorb financial shocks, but they cannot withstand a sustained, spiraling loss of confidence.

Market participants are conditioned to expect a dramatic "Minsky moment." However, the more probable reality is a slow, grinding decline characterized by a decade of flat equity prices, compressing multiples, and degrading returns—a "death by a thousand cuts" rather than one catastrophic event.

Unlike the 2008 crisis, which was concentrated in housing and banking, today's risk is an 'everything bubble.' A decade of cheap money has simultaneously inflated stocks, real estate, crypto, and even collectibles, meaning a collapse would be far broader and more contagious.

The top 10% of earners, who drive 50% of consumer spending, can slash discretionary purchases overnight based on stock market fluctuations. This makes the economy more volatile than one supported by the stable, non-discretionary spending of the middle class, creating systemic fragility.

Historically, what tears societies apart is not economic depression itself but runaway wealth inequality. A major bubble bursting would dramatically widen the gap between asset holders and everyone else, fueling the populist anger and political violence that directly leads to civil unrest.

The economy is now driven by high-income earners whose spending fluctuates with the stock market. Unlike historical recessions, a significant market downturn is now a prerequisite for a broader economic recession, as equities must fall to curtail spending from this key demographic.

For 40 years, falling rates pushed 'safe' bond funds into increasingly risky assets to chase yield. With rates now rising, these mis-categorized portfolios are the most vulnerable part of the financial system. A crisis in credit or sovereign debt is more probable than a stock-market-led crash.
