The 'Two More Tests' After Friday's $15.6B Deribit Expiry Are Scheduled Prints, Not Chart Levels: Durable Goods 12:30 UTC, UMich Final (Prelim 47.8, 1-Yr Inflation 4.6%) 14:00, CME Sept Futures Cash-Settle 15:00 on ~$8.9B COT OI; Last 4 Quarterly Expiries Fell 4/4 on D-1 and Rose 4/4 by D+14
The thin card says Bitcoin's rally faces two tests after Friday's expiry: 'post-expiry repositioning' and 'resistance near key technical levels'. Its own source (CryptoSlate, 23 Sept 2026) says something different and more checkable: the tests are a fixed clock of scheduled events on Friday 25 Sept: US durable goods at 12:30 UTC, the University of Michigan final September sentiment at 14:00 UTC, and CME's September Bitcoin futures cash settlement at 15:00 UTC, all landing after Deribit's 08:00 UTC expiry. None of them is a chart level. This card measures each one.

The Deribit leg, from the live order book rather than a vendor screenshot. Deribit's public API (get_book_summary_by_currency, pulled 23 Sept ~12:25 UTC) shows 183,039 BTC of open interest in the 25SEP26 expiry, 36.7% of all 498,900 BTC of BTC options OI on the venue. At the Deribit index of $85,431 that is $15.64B notional, which is where the '$16B' headline comes from. Calls are 107,239 BTC ($9.16B, 58.6%) and puts 75,799 BTC ($6.48B), a raw put/call ratio of 0.71. The 0.52 put/call figure the article quotes comes from ByKaranteli's gamma model, not the exchange aggregate; the two are not the same statistic. The largest single strike is $70,000 (8,792 calls, 8,133 puts), followed by $90,000 (7,286 calls, 559 puts), $100,000 (6,950 calls), $85,000 (6,734 calls) and $80,000 (6,230 calls); the largest put strike is $60,000 (5,571 puts). Minimising aggregate option payoff across the live strikes gives a max-pain strike of $76,000, roughly 11% below spot. The important point the headline misses: 63% of Deribit OI does not expire Friday. The 30OCT26 book already holds 105,172 BTC with a put/call ratio of 0.31 (80,418 calls vs 24,754 puts) and 25DEC26 holds 118,371 BTC at 0.60. Whatever dealer gamma survives Friday is more call-skewed than what expires, so the 'hedges disappear and the market is naked' framing overstates the reset.

The CME leg is smaller than it sounds and cannot deliver anything. CME Bitcoin futures are cash-settled against the CME CF Bitcoin Reference Rate (BRR), which CF Benchmarks printed at $86,037.52 at 15:00 GMT on 22 Sept; the September contract terminates on the last Friday of the month at 16:00 London, i.e. 15:00 UTC on 25 Sept. The CFTC Traders in Financial Futures report as of 15 Sept 2026 shows total CME Bitcoin futures open interest of 20,773 contracts across all months (5 BTC each, 103,865 BTC, about $8.9B at $85.4K), down 310 contracts on the week, with 111 reporting traders. The September contract is only a fraction of that, since most positions roll to October and December in the week before termination. Positioning is the familiar basis-trade shape: leveraged funds are 5,545 long vs 11,899 short (net short 6,354 contracts, 31,770 BTC), asset managers 4,528 long vs 1,768 short, dealers 6,587 long vs 3,168 short. Micro Bitcoin futures add 37,455 contracts at 0.1 BTC (3,746 BTC). A cash settlement of a net-short-by-hedgers book against a 1-hour London TWAP is a roll event, not a liquidity event.

The macro prints are second-tier, and the one that matters comes next week. The Fed raised the funds target by 25bp to 3.75-4.00% on 16 Sept 2026 (12-0 vote), so inflation expectations are the live variable. The University of Michigan preliminary September reading (published 11 Sept) was sentiment 47.8, down 7.5% on the month and 13.2% on the year, with year-ahead inflation expectations jumping to 4.6% from 4.0% (highest since June) and long-run expectations 3.4% from 3.3%; the final print is scheduled for Friday 25 Sept at 10:00 ET (14:00 UTC). Final UMich revisions are usually within a point of the preliminary. The Census Bureau's Advance Durable Goods report for August is the only Census release that day, at 08:30 ET (12:30 UTC). The heavyweight, August PCE, is not on Friday at all: BEA's release schedule has Personal Income and Outlays for August on Wednesday 30 Sept at 08:30 ET, the same day as quarter-end. If a rate-sensitive repricing is going to hit Bitcoin, the calendar says 30 Sept, not 25 Sept.

Base rates for quarterly expiry weeks, from CoinGecko daily closes (00:00 UTC snapshots, so 'D' is the price at the start of expiry day). Sept 26 2025: -3.6% on the day before expiry, +0.4% on expiry day, +10.3% by D+7, +11.4% by D+14. Dec 26 2025: -0.5%, +0.1%, +1.8%, +4.4%. Mar 27 2026: -3.6%, -3.5%, -2.7%, +3.8%. Jun 26 2026: -2.1%, +0.5%, +3.0%, +5.8%. Four for four, the day before quarterly expiry closed lower (average -2.5%); three of four expiry days were flat within 0.5%; and four for four Bitcoin was higher two weeks later (average +6.4%). The pattern that repeats is pre-expiry pressure toward max pain followed by a post-expiry drift higher, which is the opposite of the 'expiry then crash' story. Four observations is a small sample and Sept 2025's +11% came off a different regime (BTC was $109K then; the 365-day range is $58,566 on 1 Jul 2026 to $124,740 on 7 Oct 2025).
What the article gets right: the sequencing. Deribit's 07:30-08:00 UTC TWAP settlement, then durable goods, then UMich, then CME, is an accurate clock, and the equity-side precedent (IBIT's roughly $5B 18 Sept expiry, its largest, with max pain at $40 per Crypto Briefing) did pass without incident. What it gets wrong is proportion: it stacks three 'tests' of very different weight into one dramatic day while the actual rate-sensitive catalyst (PCE) and quarter-end both fall five days later. The peer-reviewed reversal effect it cites (Finance Research Letters 2026, Deribit expiries 2021-2023) is an intraday two-hour phenomenon strongest under negative gamma, and the article's own model places the market in positive gamma at $86K.
Correction to the parent card: the 'two more tests' are not 'post-expiry repositioning and resistance near key technical levels'; per the cited article they are the 12:30/14:00 UTC US data releases and the 15:00 UTC CME futures settlement. Spot at the time of writing: CoinGecko $85,395 (23 Sept 2026 daily), Deribit index $85,431.

Key Takeaway
Friday's $15.6B Deribit expiry is followed by second-tier US data and a cash-settled CME roll, not by a technical showdown; the rate catalyst (August PCE) and quarter-end land on 30 Sept, and the last four quarterly expiries all dipped the day before and were all higher two weeks later.
The thin card says Bitcoin's rally faces two tests after Friday's expiry: 'post-expiry repositioning' and 'resistance near key technical levels'. Its own source (CryptoSlate, 23 Sept 2026) says something different and more checkable: the tests are a fixed clock of scheduled events on Friday 25 Sept: US durable goods at 12:30 UTC, the University of Michigan final September sentiment at 14:00 UTC, and CME's September Bitcoin futures cash settlement at 15:00 UTC, all landing after Deribit's 08:00 UTC expiry. None of them is a chart level. This card measures each one.
