Fed Easing & SEC Progress Counter Seasonal Weakness

Key takeaways for the month

September 2025 bucked its historical trend of negative price performance, supported by a series of regulatory and macro catalysts. The Fed delivered its first rate cut of the year, reducing rates by 25 bps to 4.00–4.25% and citing rising labor market risks, though forward guidance remained cautious and less definitive than markets had anticipated. The SEC approved generic listing standards for commodity-based trust shares, streamlining the path to list crypto ETPs beyond BTC and ETH. CME announced options on Solana and XRP futures for October, extending institutional-grade positioning and hedging tools. Despite choppy price action, fund flows remained robust at $3.8B for the month, with investor appetite picking up after the FOMC and strong focus on Bitcoin.

Mega-Cap Strength Returns: Digital asset performance returned to favoring larger-cap tokens again, with the CF Ultra Cap 5 Index leading September's gains, rising 2.41% for the month and lifting its year-to-date return to +18.62%. The CF Free-Float Broad Cap Index added 2.17% (YTD +14.72%), and the CF Diversified Large Cap Index rose 0.70% (YTD +11.60%), while the CF Digital Culture Index edged up 0.78% (YTD −40.59%). Higher-beta cohorts lagged: the CF Smart Contract Platforms Index fell 1.75% (YTD −7.59%), and the CF DeFi Index declined 10.89% (YTD −21.55%). Overall, September favored liquid mega-caps, while DeFi and smart contract names underperformed.

Individual Movers: Avalanche surged 28.3% in September, driven by institutional initiatives including the launch of treasury vehicles to accumulate AVAX. Dogecoin jumped 7.3%, driven by renewed memecoin momentum and optimism around the ETF launch in late September. Fantom slumped 28.2%, weighed down by weak fundamentals and capital outflows. Uniswap fell 21.1%, despite ongoing protocol upgrades and expansion into new chains.

Bitcoin Dominates Monthly Inflows: September saw continued inflows into digital asset funds, with investors allocating roughly $3.8 billion. Bitcoin accounted for the lion’s share at $3.2 billion, while Ether lagged with a more modest $79 million. Regionally, North America dominated activity, recording net inflows of about $4.6 billion, compared to Europe’s $330 million, highlighting the relative strength of U.S. investor demand.

SOL and XRP Futures Lead Open Interest Growth: Bitcoin futures saw strong growth in September, with open interest rising 17.5% from 13,501 to 15,336 contracts. Ether futures also gained momentum, with open interest climbing 13.2% to a record 15,607 contracts, supported by robust trading activity that peaked at 88,733 contracts at month-end. Meanwhile, Solana and XRP futures posted substantial expansion amid heightened investor interest: Solana’s open interest surged 86.6% to 11,146 contracts, with volumes exceeding 24,000 contracts, while XRP’s open interest jumped 50.1% to 5,901 contracts, accompanied by a material increase in trading volumes.

On-Chain Activity Moderates; Bitcoin Holds Steady: Bitcoin’s active addresses in September grew slightly to 10.7 million from 10.5 million in August (1.6%), signaling steady network activity. Ethereum saw a sharp pullback, with active addresses falling from 37.3 million to 30.6 million (-17.8%), reflecting weaker on-chain engagement. Solana experienced the steepest drop, as active addresses declined from 50.0 million to 40.9 million (-18.2%).

DeFi Growth Pauses at $417B: Total Value Locked (TVL) in DeFi measures the total assets deposited in decentralized finance protocols, expressed in USD. It is a key indicator of the health and growth of the DeFi ecosystem. Over the past month, TVL in DeFi protocols rose just 0.1%, reaching approximately $417 billion. Growth stalled as Ether and Solana pulled back following their recent rally.

Hash Rate Reaches Record Levels: Bitcoin’s hash rate grew significantly in September, rising 9.7% to 1050 exahashes per second. Mining difficulty, which measures the computational effort required to mine a new block and adjusts to maintain consistent block creation times, increased by 5.1% after a period of faster block times in late September. The next difficulty adjustment, expected in the mid October, is currently projected to be a 0.8% increase.

Ethereum Fees Decline 10% as DEX Activity Remains Dominant: Examining Ethereum’s total fees and their sector breakdown offers insight into the use cases driving network revenue. Ethereum layer-1 fees declined 9.7% month-over-month, falling to $35.9 million in September from $39.8 million in August. Decentralized exchanges generated the largest share at 44.7%, followed by lending protocols at 22.7% and liquid staking at 14.7%. Derivatives contributed 17.5%, while real-world asset tokenization accounted for just 0.7%, highlighting the continued dominance of DEX activity in fee generation.
