What happens to investments in a market crash?
In the UK, when markets experience a crash, the value of investments such as shares and funds can fall quickly. The extent of the fall depends on the type of assets held, how diversified the portfolio is, and how long the downturn lasts.
Behind this question are often deeper concerns:
Could I lose everything?
Should I sell before it gets worse?
How long do crashes last?
Will my retirement be affected?
Understanding what actually happens during a market crash can reduce unnecessary panic.
What is a market crash?
A market crash is typically defined as a rapid and significant decline in asset prices.
This might involve:
Equity markets falling 20% or more
Sharp declines over days or weeks
Widespread negative sentiment
Crashes are uncomfortable.But they are not new.
Markets have experienced severe downturns before and have historically recovered over time, although past performance is not a guarantee of future outcomes.
What happens to different types of investments?
Shares and equity funds
These are usually the most affected.
If markets fall 25%, a portfolio heavily invested in shares may fall by a similar amount.
Bonds
High-quality government bonds may fall less, and in some cases may rise during periods of equity stress. Corporate bonds can also decline, depending on economic conditions.
Cash
Cash does not fall in nominal value during a crash, but it may lose value gradually to inflation over time.
Diversified portfolios
Portfolios that combine shares, bonds and other assets often experience smaller declines than fully equity-based portfolios.
Diversification reduces concentration risk.It does not eliminate volatility.
A simple example
Imagine:
You hold a £500,000 portfolio
70% in global equities
30% in bonds
If equities fall 30% and bonds fall 5%:
Equity portion: £350,000 → £245,000
Bond portion: £150,000 → £142,500
Total portfolio value: £387,500
A decline of £112,500.
The fall feels significant.
But the portfolio still holds assets.It has not disappeared.
What matters next is behaviour.
What usually happens after a crash?
Historically, markets have eventually recovered, though the time taken varies.
The danger often lies not in the crash itself, but in:
Selling after the fall
Crystallising losses
Missing the early stages of recovery
Market recoveries can occur quickly and unpredictably.
Investors who exit entirely may struggle to re-enter at the right time.
The behavioural layer
When markets fall sharply, emotions rise.
Common reactions include:
Urge to sell
Fear of further losses
Regret about past decisions
Loss of confidence in strategy
But the key question becomes:
Was the portfolio designed with this volatility in mind?
If the risk level was appropriate at the outset, downturns are uncomfortable but expected.
If the fall feels intolerable, the issue may be structural rather than temporary.
A more useful question
Rather than asking only:
What happens to investments in a market crash?
A more grounded question might be:
Is my portfolio structured in a way that allows me to tolerate downturns without making reactive decisions?
That shifts the focus from predicting crashes to designing resilience.
Some of the most common practical questions people ask about market crashes are below.
Do you lose all your money in a market crash?
No. Investment values may fall significantly, but diversified portfolios typically retain substantial value unless assets are sold.
How long does it take markets to recover?
Recovery periods vary. Some recoveries have taken months, others several years.
Should I sell during a market crash?
Selling locks in losses. Decisions should be based on suitability and long-term planning rather than short-term fear.
Are bonds safe during a crash?
High-quality bonds often behave differently from shares, but they are not entirely risk-free.
A calm place to think first
If market volatility is making you uneasy, there is rarely a need for immediate action.
Often the first step is to clarify:
What your portfolio is designed to achieve
When you will need the money
Whether the risk level matches your capacity for loss
Evoa exists to provide that quiet thinking space — before advice, before action.
