In September, the spot trading volume on cryptocurrency exchanges fell to $1.67 trillion, marking its lowest level since June. According to panel data from The Block, there was a 9.7% decline compared to August. This drop was complemented by a change in direction of institutional fund flows. On a monthly basis, spot Bitcoin 
$91,081 ETFs saw a net inflow of $3.53 billion, following a net outflow of $751.1 million in August. Despite diverging distributions in centralized and decentralized exchanges, Binance maintained its leadership position.
September’s Sharp Decline in Cryptocurrency Spot Volumes
Spot volumes on cryptocurrency exchanges dropped in September, with Binance leading the pack with a monthly volume of $636.5 billion. In August, Binance’s volume stood at $737.1 billion. Following Binance, Bybit recorded a volume of $132.1 billion, Gate.io saw $124 billion, and Bitget reached $117.9 billion. The total volume logged at $1.67 trillion, about $200 billion lower than August’s $1.85 trillion. This monthly volume was still above June’s low of $1.1 trillion. Factors such as geographic parity, volatility dynamics, holiday periods, and shifts in risk appetite influenced the monthly volume.
Meanwhile, decentralized crypto exchanges saw their volume slightly retreat from $368.8 billion to $363.4 billion during the month. Uniswap’s volume decreased from $143 billion to $106.5 billion, whereas PancakeSwap’s volume surged from $58.7 billion to $79.8 billion. Changes in exchange preferences and liquidity mining advantages caused shifts in inter-network volumes. Additionally, inventory management by market makers and arbitrage bridges affected the monthly volume outlook.
ETF Inflows Recover Amid Volume Decline
Despite the slowdown in spot trading, spot Bitcoin ETFs in the US attracted a net inflow of $3.53 billion in September. Following August’s net outflow of $751.1 million, this upward shift is associated with expectations of a possible change in Fed’s monetary policy and a search for off-balance-sheet investments. Despite sharp price movements, demand through regulated investment products indicates that risks are concentrated in institutional channels.
This divergence in fund flows emphasized the difference between high individual spot trading activity and institutional allocation. During periods of reduced leverage and strengthened collateral, swap-supervised instruments were preferred. The weakening in volume points to short-term trading activity, while inflows into ETFs suggest a strengthening intention to hold rather than sell in the medium term.
