Bitcoin’s Late-Summer Rally Meets Fed Rate-Hike Odds and Senate Vote
By Drooid · · How we work
Core Event
After a two-year low near $60,000, Bitcoin surged past $70,000 in late August and traded above $78,000 in early September. The rally follows a roughly 50 % drop from its October 2025 peak of more than $126,000. Traders are now weighing two imminent tests: a Federal Reserve rate decision slated for the week of September 16 and a procedural Senate vote on the GENIUS Act scheduled for September 15.
Background & Context
The price rebound comes after months of gloom. From its October 2025 high, Bitcoin fell about half, prompting a prolonged outflow period for spot Bitcoin exchange-traded funds (ETFs). In the week of August 17, ETF inflows briefly reached nearly $2 billion, but sentiment shifted sharply in early September.
Data & Statistics
- Price levels: Late-August rally past $70,000; early-September trading above $78,200; price stalled near $77,000 as of the latest data.
- Options market: The 25-delta skew turned positive on August 20, indicating premium demand for bullish calls. Open interest for the December 25 expiry clusters at the $80,000 strike with about $710 million notional value and at $100,000 with roughly $530 million.
- ETF flows: Reuters reported near-$2 billion of inflows the week of August 17. TradingView recorded net outflows of roughly $450 million over September 8-10, including a single-day redemption of $282.6 million on September 10. Economies.com noted $462 million of outflows in the most recent week.
- Derivatives pressure: The derivatives pressure index fell from –25.36 to –60.8 in the past 24 hours, remaining below zero since September 6.
- Open interest: Coin-denominated open interest dropped from 321,497 BTC on September 3 to 278,151 BTC on September 11, a 13.5 % decline.
Official Statements & Responses
Matthew Dibb, COO of Stack Funds, said Bitcoin had been “oversold” for an extended period, suggesting the rally may reflect a corrective bounce. Sean Dawson of Derive.xyz linked the bullish options skew to a rotation back into crypto after capital was drawn to the SpaceX IPO. Joseph Edwards warned that any Fed rate hike would likely dampen the rally. Brian Vieten of Siebert Financial argued that Treasury buybacks could revive a “debasement trade,” supporting demand for scarce assets like Bitcoin.
Conflicting Reports & Gaps
- ETF flow data: Reuters highlighted a near-$2 billion inflow week of August 17, while TradingView documented a $450 million outflow over September 8-10, and Economies.com reported $462 million of outflows in the most recent week. The timing and magnitude of these flows differ across sources.
- Institutional demand: Reuters cited renewed demand for Bitcoin ETFs, whereas Economies.com described weakening institutional demand, indicating a lack of consensus on current investor sentiment.
Why It Matters
The outcome of the September 15 procedural vote on the GENIUS Act and the Fed’s September 16 rate decision could shape liquidity conditions for risk assets. A rate hike—estimated at an 86 % chance by market participants and 86.5 % by Pluang—typically reduces appetite for volatile assets, while legislative clarity on token classification could either remove legal ambiguity or, if delayed, sustain market uncertainty.
What’s Next
The Senate will hold a procedural vote on the GENIUS Act on September 15, followed by the Federal Reserve’s key interest-rate meeting on September 16. Market participants will watch these events for cues on Bitcoin’s near-term trajectory.
