A bear market is a broad and sustained fall in asset prices, usually accompanied by pessimism, risk aversion, and weaker expectations about the economy.
How the term is used
In equity markets, people often use a decline of around 20% from a recent peak as a rule of thumb. That threshold is conventional, not a law of economics. The deeper point is that a bear market reflects a persistent shift in expectations and risk appetite, not just a short-lived pullback.
Why economists care
Bear markets matter because falling asset prices can affect the wider economy through several channels:
- lower household wealth can reduce spending,
- tighter financing conditions can cut investment,
- higher uncertainty can delay hiring and expansion,
- weaker balance sheets can amplify recession risk.
This is why a bear market can both reflect macro weakness and intensify it.
Practical example
If investors come to expect lower profits, higher interest rates, or recession, they discount future cash flows more heavily and demand larger risk premia. Share prices fall, credit becomes more expensive, and the decline can feed back into real activity.
Knowledge Check
### What distinguishes a bear market from an ordinary short-term dip?
- [x] A persistent decline tied to weaker expectations and higher risk aversion
- [ ] Any one-day fall in prices
- [ ] A rise in government spending
