EXPLAINER
Why crypto prices fall overnight, and how to tell a reason from a coincidence
Most overnight moves have a liquidity explanation rather than a news one. How to work out what actually happened before accepting the first headline.
Quick answer
Overnight moves are usually thin order books plus leverage unwinding, not news. Check whether liquidations spiked and whether other assets moved together before accepting any single-cause explanation.
A coin is down nine per cent when you wake up and there is already an article explaining why. The explanation is often reverse-engineered from the chart. Here is how to check it.
Start with liquidity, not news
Crypto trades every hour of every day, but the people and desks providing liquidity do not. Order books thin out overnight in the dominant trading regions, and a sell order that would move price half a per cent at midday can move it several per cent at four in the morning. Same order, different book.
Then check leverage
Much of the volume in this market is leveraged. When price drops enough to breach margin thresholds, positions are closed automatically, which sells into an already thin book, which pushes price further, which triggers the next tier. That is a cascade, and it needs no news whatsoever to start.
Liquidation data is public on the major venues. A move accompanied by a liquidation spike is a mechanical move. It will often retrace a meaningful part of itself within a day, because nothing about the asset changed.
Then ask what else moved
This is the fastest test available and almost nobody applies it. If Bitcoin, Ethereum, XRP and most of the top fifty all fell by similar percentages within the same hour, then an article explaining the drop through one project’s partnership news is wrong. Correlated moves have correlated causes: macro data, a large forced seller, or a leverage cascade.
The market table on our homepage shows 24-hour and 7-day change side by side for exactly this reason — it takes a few seconds to see whether a move was idiosyncratic.
Reasons that genuinely do move a single coin
- Exchange listings and delistings.
- Token unlocks, which are scheduled and public in advance.
- Regulatory or legal developments naming the asset or its issuer.
- Protocol failures and exploits.
Note that three of those four are knowable ahead of time. Unlock schedules in particular are published, and a large one landing is one of the few genuinely predictable sources of selling pressure.
When the honest answer is “no reason”
Plenty of moves have no clean explanation. Markets move because more people wanted out than in at that moment. We would rather say that than manufacture a cause, and you should be sceptical of any outlet that never does.
Key takeaways
- Crypto trades continuously, so moves cluster when liquidity is thinnest.
- A cascade of forced liquidations can move price with no new information at all.
- If the whole market moved together, a coin-specific explanation is probably wrong.
Risk notice
Cryptocurrency prices are volatile and you can lose the full value of a position. Nothing here is a price prediction or a recommendation to buy or sell. Do your own research.
Frequently asked questions
Do overnight drops usually recover?
Purely mechanical moves driven by liquidations often retrace part of the fall within a day or two. Moves driven by genuine new information generally do not. Distinguishing them is the whole point of the checks above.
Where can I see liquidation data?
The major derivatives venues publish it, and several aggregators consolidate it. Look for a spike coinciding with the move rather than at the absolute number.
