Summary
Bitcoin demonstrated the strongest directional momentum, climbing from roughly $109,000 at the start of September to $117,000 by mid-month, reflecting broad institutional repositioning ahead of the Fed decision. Ethereum followed a similar pattern, advancing from $4,300 to $4,600 before retracing to approximately $4,000 by month-end—a pattern consistent with profit-taking after the initial relief rally. Solana exhibited higher volatility but outperformed its larger peers, with gains exceeding 10% as it reached the mid-$240s, though it subsequently eased back to the $200 range. The divergent performance across major cryptocurrencies reflected the rotation of capital toward higher-beta assets within a risk-on environment, supported by renewed ETF inflows and softer macroeconomic data.
Lending conditions underwent material improvement following the rate cut, with cascading effects throughout both centralized and decentralized finance. Stablecoin borrowing rates on decentralized platforms, which had generally ranged between 6.7% and 10% APR in late 2025, became more accessible as Fed-driven liquidity eased cash borrowing costs. This improvement in funding conditions reinvigorated institutional participation in crypto lending, with DeFi protocols including Morpho, Plasma, and partnerships such as PayPal-Spark expanding their institutional on-chain lending capacity and stablecoin liquidity offerings.
Derivatives markets reflected strong institutional demand for leveraged exposure. CME Bitcoin futures basis traded within a 6–9% annualized range throughout September, peaking near 9% in late month before moderating, while Ethereum's basis followed a similar corridor of 6–10%. Solana's basis remained elevated at 12–20%, consistent with its higher volatility profile and active on-chain lending dynamics. The elevated and persistent basis levels indicated capital rotation into basis-arbitrage trades, with front-month futures consistently trading above spot prices—a structural signal of sustained institutional demand for leverage. Volatility compression into the FOMC meeting suggested orderly positioning ahead of the rate decision, with stable liquidity maintained across both derivatives and spot markets.
