In August 2025, Binance Futures' monthly trading volume reached $2.626 trillion, which not only represented a month-on-month growth of approximately 2.9% compared to July's $2.552 trillion, but also set a historical peak since the platform launched its futures business in 2019. This breakthrough was driven by multiple market factors resonating together: in that month, Bitcoin's monthly volatility climbed to 68% (up 12 percentage points from July), with prices fluctuating violently in the range of $42,000 - $58,000, providing ample arbitrage opportunities for leveraged trading; meanwhile, institutional investors' participation significantly rebounded. According to data from crypto analytics firm Glassnode, traditional financial institutions managing over $1 billion entered the market through compliant derivatives channels, with a net increase of $12.7 billion in a single month, doubling the average monthly level of the second quarter, among which hedge funds' long positions in BTC/USD perpetual contracts accounted for 42%, the highest since November 2024.
From the perspective of market structure, changes in open interest are more indicative of the trend of capital inflow. In August, the open interest of Binance futures increased from 8.3 billion dollars at the beginning of the month to 10.9 billion dollars at the end of the month, with a monthly increase of 31.3%. The distribution of positions shows that 70% of the new positions are concentrated in medium to large orders of 1-10 BTC, indicating that the incremental capital in the market is mainly institutional-level allocation rather than retail short-term speculation.
Regarding the sustainability of the derivatives market, multiple analysts pointed out two core supports: first, the depth and liquidity of the spot market, with the current daily trading volume of Bitcoin spot stable at 35 billion - 45 billion dollars, and the bid-ask spread maintained within 0.02%, providing a basis for futures arbitrage and hedging; second, the supply capacity of stablecoins. As of August 31, the total market value of global stablecoins reached 298 billion dollars, an increase of 4.2% compared to the previous month, with USDT (152 billion) and USDC (78 billion) collectively accounting for 84%. The proportion of short-term government bonds in stablecoin reserve assets has risen to 68%, with ample liquidity reserves providing a stable settlement medium for derivatives trading.
From the perspective of funding sources, the dominant role of U.S. institutions has become increasingly evident. In August, net inflows into U.S. spot Bitcoin ETFs reached 9.4 billion dollars, setting a new monthly high since March 2024, with BlackRock's IBIT net inflow at 4.2 billion dollars. During the same period, the Coinbase premium index (which measures the premium level of U.S. spot prices relative to the global average) averaged 0.32%, an increase of 0.15 percentage points from July, indicating strong buying power in the U.S. market, which forms a key support for maintaining the upward trend of Bitcoin prices. In contrast, the Asian market shows a high volatility characteristic dominated by retail investors. Data shows that on August 12, during a day when Bitcoin rose more than 8%, small orders from retail exchanges in South Korea and Vietnam (such as Upbit and Binance Vietnam) accounted for 63%, with transaction frequency 5-8 times higher than institutional users, and the rapid inflow and outflow of short-term capital often exacerbates price volatility.
Looking ahead to September, market focus will be on the Federal Reserve FOMC meeting (September 17-18). Currently, the CME FedWatch tool indicates that the market expects a 78% probability of maintaining interest rates, but there is increasing divergence regarding the expectation of rate cuts within the year—26% of institutions believe that rate cuts will start in November, while 41% predict that the timing of rate cuts will be delayed until the first quarter of 2026. The uncertainty of interest rate policy may lead to high volatility in the crypto derivatives market in the short term, and some institutions have begun to hedge risks by buying put options. In late August, the trading volume of put options with a strike price of 2500 dollars expiring in September increased by 89% month-on-month, reflecting a rise in cautious sentiment in the market.
