Binance has launched a new Indication of Interest (IOI) feature for spot trading and fixed-rate crypto loans, so that institutional clients can execute large transactions with reduced market impact. The new Binance Spot and Loan IOI is designed for qualified users and allows them to privately signal buy, sell, borrow, or lend intentions without placing binding orders on public order books. The feature targets one of the long-standing challenges in crypto markets: executing large trades without triggering price slippage or exposing sensitive trading intentions. New feature brings tools that prioritize liquidity and efficiency In traditional financial markets, institutional traders often rely on IOIs to gauge liquidity while minimizing disruption
