Binance BTC Open Interest Sees Its Deepest 30D Drop Since August 2023

Bitcoin’s derivatives market has just gone through one of its strongest leverage resets in the current cycle. On Binance, the BTC Open Interest 30D Change dropped to around -$2.2 billion on February 17, followed by another extreme reading near -$2.25 billion on February 28. This marks the deepest 30-day contraction since August 2023, with the recent decline coming in at roughly four times larger than the levels seen back then. This was not a routine pullback in futures activity. The scale of the move points to a much broader deleveraging event, where a large amount of leveraged exposure was flushed out of the market in a short period of time. From a market structure perspective, this kind of move can matter a lot. Sharp open interest contractions usually reflect forced positioning cleanup rather than normal market cooling. In other words, excess leverage is being removed, and crowded trades are being unwound. That does not automatically mean an immediate bullish reversal. But if Bitcoin price begins to stabilize while open interest pressure starts to normalize, this type of reset can leave the market in a much cleaner and less crowded state for the next major move.
