Bitcoin is more than halfway through its historically weakest month, and September's usual selloff has stayed contained despite a barrage of policy and macroeconomic headwinds.After rallying 25% in August to around $81,000, expectations were that it would surrender much of those gains. September has delivered an average loss of roughly 3% since 2013.Instead Bitcoin is down 1.5% this month. With under two weeks remaining it is up about 32% for the quarter, on course for its first positive quarterly close since the third quarter of 2025.It trades at $78,000, roughly back to where it sat before Wednesday's Fed rate hike.The Absence of a Reaction Is the Data PointTwo events this week would normally have moved price meaningfully.The Clarity Act failed to secure the 60 votes needed to advance in the Senate, attracting just 49. Bitcoin briefly fell below $74,887 Tuesday before stabilising quickly.The Fed then raised rates 25 basis points to 3.75%-4.00%, its first increase since July 2023."What stands out to me is that Bitcoin has hardly budged at all in response to two objectively bad pieces of news," said Mitchell Askew, head of Blockware Intelligence at Blockware. "A 25-basis-point hike and the CLARITY Act failing to pass are both headlines that, in a different market environment, would have sent price meaningfully lower. Instead, we got basically nothing."Seller Exhaustion Is the Proposed ExplanationAskew reads the non-reaction as a supply signal rather than a demand one."Anybody who was going to sell bitcoin based on events like these has already sold. They no longer have coins to sell. That is an incredibly positive sign for the medium to long term, and it is exactly what you tend to see in the later stages of a bottoming process."The positioning data is consistent with that. Santiment showed BTC-denominated open contracts falling 13.5% between September 3 and 11 against a 5% price decline, leaving positioning roughly 20% below pre-rally levels. K33 Research found open interest across futures and perpetuals below its yearly average.There is a competing reading worth noting. Thin positioning also means fewer buyers, and a market that does not fall on bad news may simply lack participants in both directions. Talos recorded Bitcoin buying conviction at 3%, down from 10%, with a 28% net tilt into stablecoins ahead of the Fed.Exhausted sellers and absent buyers produce the same chart. They imply different things about what happens next. Four Headwinds Arrived at OnceThe pressure was not limited to policy.WTI crude climbed above $106 Tuesday, a five-month high, as Middle East tensions persisted. Saudi Arabia's closure of the East-West pipeline that bypasses the Strait of Hormuz left production at 6.238 million barrels per day, the lowest since 1990.The Dollar Index topped 100, its highest in over a month. Sustained dollar strength tightens financial conditions and typically weighs on risk assets.The Bank of Japan lifted its benchmark to a 31-year high, raising the cost of the yen carry trade that funds positions in dollar assets.Sygnum Argues Rising Yields Are Not Automatically BearishFabian Dori, chief investment officer at Sygnum Bank, offered the mechanism behind the resilience."It's not a one-way street. You see yields rising, and at the same time Bitcoin and gold outperforming. If rising rates are an indication of debasement risk and sovereign counterparty risk, then for store of value assets that is actually a positive driver."The correlation data supports the asymmetry. Bitcoin's 90-day correlation with the 10-year Treasury yield sits at −0.17 against gold's −0.41, meaning gold responds more than twice as strongly to the same rate move.Dori also pushed back on the standard framing for what comes next. Markets price three further quarter-point increases by April 2027, taking the funds rate to 4.50%-4.75%."I do not fully agree that rates need to fall in order for digital assets to outperform," he said.The SEC Moved the Day After Congress FailedThe regulatory picture improved within 48 hours of the Senate vote.The SEC unveiled its long-awaited innovation exemption for tokenized securities venues Thursday, allowing qualifying platforms to facilitate onchain trading of stocks under specified conditions.Chairman Paul Atkins had said the agency would act regardless of whether the legislation passed, taking decisive action within its statutory authority.LMAX Group markets strategist Joel Kruger framed what that leaves. "The failure to advance the legislation delays a statutory framework, but it does not prevent the SEC and CFTC from continuing to provide guidance under existing authority, leaving an important regulatory pathway open."The durability gap remains. Rules made under existing authority can be unmade by a subsequent administration, which is the problem legislation was meant to solve.Kruger Sees Asymmetry in What FollowsThe argument for upside rests on how little it would take."If the market has been this resilient when the news flow has been challenging, even a modest improvement in macro, geopolitical or regulatory conditions could provide the catalyst for the next major leg higher," Kruger said.That is the same asymmetry he identified before the Fed decision, when he saw greater potential for an outsized move higher if the central bank failed to deliver the tightening markets had priced.The dot plot arguably supplied a version of it. The median points to one more hike in 2026 — 50 basis points total — below the 75 Bank of America and RBC forecast and the roughly 87.5 markets had priced.Next Week's Seasonality Is the Near-Term ConcernBitcoin has historically fallen an average of 2.5% in the year's 38th week, recording gains on just four occasions, per Coinglass.That is the one piece of the setup that offers bulls no comfort.The counterweight is the quarter that follows. Bitcoin has averaged a 77% gain in the fourth quarter, according to CoinDesk data.Both figures are averages across small samples, and neither is a forecast. The seasonal case for weakness next week is the same class of evidence as the seasonal case for strength in October — which is to say, weak evidence pointing in opposite directions.Above price, Glassnode data shows nearly 8% of supply was acquired between $80,000 and $82,000, with the US spot ETF cohort's average cost basis in the same band and the 50-week moving average at $81,081.
