The calm can hide a buildup of risk
Before many major market crashes, a long upswing encourages investors to treat rising prices as proof that risk has faded. More borrowing flows into assets, and buyers grow comfortable paying high prices because they expect someone else to pay more later. The unsettling pattern is not simply that prices rise; it is that confidence rises alongside dependence on borrowed money and continued price gains.
Why a small shock can become a rout
Borrowing magnifies both gains and losses. An investor who buys with borrowed money may have to sell if the asset’s value falls below a lender’s requirements. When many investors are leveraged in similar ways, an initial decline can force a wave of sales. Those sales push prices lower, prompting more forced selling and making credit harder to obtain.
That feedback loop can turn a manageable setback into a crash. The original trigger might be a change in interest rates, a borrower’s failure, or disappointing news; it does not need to be dramatic on its own. What matters is how exposed the market has become before it arrives.
A warning pattern, not a countdown
Surging prices, easy credit, and widespread confidence have appeared before serious downturns, but they do not provide a dependable date or guarantee that a crash is next. The deeper warning is a market where many participants have made the same bet and may be forced to unwind it at once. When confidence finally breaks, the exits can be far narrower than they looked on the way in.
