# Isolated Margin

Isolated Margin is **the margin balance allocated to an individual assets contract**. By default, all Bit Bank futures contracts are isolated markets, requiring users to deposit and withdraw separately for each asset they wish to trade. With Bit bank [cross-margin account](https://docs.bit-bank.io/confidential-futures-and-exchange-platform-tech-docs/futures/futures-on-bit-bank/broken-reference), users can seamlessly trade different markets with fewer transactions and less hassle.
