BAS Funding Rate (BNB Attestation Service)

The BAS funding rate is a periodic payment between long and short traders on BNB Attestation Service perpetual futures, designed to keep the contract price anchored to the spot index. When the rate is positive, longs pay shorts; when negative, shorts pay longs. It is the main ongoing cost (or income) of holding a leveraged BAS perpetual position.

A persistently positive BAS funding rate signals crowded long positioning and bullish sentiment — longs keep paying to stay in the trade. A negative rate signals short-side dominance and bearish sentiment. Extreme funding rates in either direction often indicate an overcrowded trade and raise the risk of a sharp reversal or short squeeze/long squeeze.
