Q3 trading volume down 27.5% from previous quarter; average open interest up 11%

Q3 2026 aggregate spot and derivatives trading volume across crypto exchanges fell 27.5% quarter-over-quarter to $12 trillion, marking a third consecutive quarterly decline, according to TokenInsight's Q3 2026 exchange report released on the 2nd. Spot volume dropped 55% from $4.5 trillion in Q2 to $2 trillion, while derivatives volume stood at $12 trillion, down from $16.5 trillion total market volume in Q2. Average futures open interest moved counter to the volume trend, rising 11% to $90 billion. Compared with Q4 2025's $26.4 trillion, Q3 volume was less than half that level. The divergence between falling turnover and rising open interest suggests traders are maintaining leveraged positions despite reduced market activity. Watch for whether open interest unwinds or volume stabilizes in Q4 to gauge whether the three-quarter contraction is bottoming.
