A stock market correction and a crash both involve falling prices, but they describe very different types of sell-offs.
A correction is generally defined as a decline of at least 10% from a recent market high. A crash has no fixed percentage threshold and usually refers to an unusually fast and severe drop caused by panic, financial stress or an unexpected shock.
A bear market, meanwhile, is typically defined as a decline of 20% or more from a recent peak.
Correction, crash and bear market compared
Corrections are a normal part of long-term market cycles. They can last from days to months and often occur even when the broader economy remains healthy.
Since 1980, the S&P 500 has experienced an average intra-year decline of about 14%, even though its average full-year return remained positive, according to Fidelity.
A crash is different because speed matters. The 1987 Black Monday collapse, the 2008 financial crisis and the rapid COVID-19 sell-off in 2020 are commonly described as crashes because prices fell sharply in a short period.
What causes a market correction?
Corrections can be triggered by high valuations, weaker earnings, rising interest rates or changes in investor expectations.
Higher Treasury yields can pressure stocks by making bonds more attractive and increasing borrowing costs. Recent concerns about AI valuations and leverage have also contributed to sharp market sell-offs.
Crashes usually require a stronger catalyst, such as a banking crisis, recession shock, geopolitical event or forced selling caused by leverage.
Does a correction mean a crash is coming?
Not necessarily. Most corrections do not develop into full bear markets or crashes.
Fidelity notes that US stocks have historically recovered from every broad market correction, although the timing of the rebound has varied considerably.
That is why investors often focus less on predicting the exact bottom and more on whether the forces driving the decline are temporary or signal deeper economic problems.
Recent warnings of a possible 15%–20% market correction show why the distinction matters. A double-digit decline can feel severe without necessarily signaling a financial crisis.
The simplest rule is that a correction describes how far the market has fallen, while a crash describes how violently and quickly that decline occurs.
