What Is Exchange Reserve?
Exchange reserve (also called exchange balance) is the stock of coins sitting in wallets labeled as belonging to centralized exchanges. It is a level, not a flow. Exchange flows and netflow describe coins moving in or out; the reserve is what remains on the venue after those moves.
How Exchange Reserves Are Read
A rising reserve means more coins are on exchanges, which can increase readily sellable supply. A falling reserve means coins are leaving for self-custody or other venues, which can tighten immediately available supply. The read is imperfect: wallet labels can be wrong, exchanges reorganize cold storage, and coins can sit on an exchange without being sold.
Compare the reserve with price, volume, and the size of inflows, rather than treating one day's change as a signal.
Why It Matters for Traders
Reserves help you judge how much supply could hit the book if holders decide to sell, and whether a rally is happening while coins are still moving onto venues. It is context for risk, not a standalone entry rule.
How Perps Traders Use This
Use reserve trends as background next to funding, open interest, and liquidations. A sharp inflow into reserves during a rally can be a reason to cut leverage. A long decline in reserves does not, by itself, tell you when price will rise.
Common Mistakes
- Treating a single exchange's wallets as the whole market's supply.
- Ignoring known custody reshuffles that look like inflows or outflows.
- Assuming coins on an exchange will be sold, or coins off an exchange will not be.
