The United States Senate votes at 14:15 Eastern today on whether to open debate on the CLARITY Act, and it needs sixty. Twenty-three hours and forty-five minutes later, at 14:00 Eastern on Wednesday, the Federal Reserve publishes a rate decision alongside a Summary of Economic Projections and a dot plot. Two Washington events inside twenty-four hours, both capable of moving the same market, and the second one is the quarterly meeting where the committee has to write its forecasts down.
Between those two events sits a derivatives market that changed its mind twice in forty-eight hours. On Monday this desk reported that perpetual funding had crossed above the September futures basis for the first time in the week — +195 basis points, a 300bp swing in one session, leveraged demand piling into the no-expiry instrument. By this morning’s 00:00 UTC print that crossover was gone and then some: funding sits 387 basis points below the September basis. A 582 basis-point round trip in a single session.
The reversal, print by print
Binance’s BTCUSDT perpetual funding rate is set every eight hours. The four prints that matter, annualised:
- 14 Sep 00:00 UTC — 0.007157% per interval, 7.837% annualised. This was Monday’s crossover print.
- 14 Sep 08:00 UTC — 0.008037%, 8.801%. The peak.
- 14 Sep 16:00 UTC — 0.004220%, 4.621%. Roughly halved in eight hours.
- 15 Sep 00:00 UTC — 0.003563%, 3.901%.
Against that, the September basis at the 06:10 UTC snapshot. Binance’s COIN-M quarterly BTCUSD_260925 last traded at 77,790.0 against an index of 77,623.41939719: a premium of 0.2146% over 10.0764 days to the 25 September settlement, or 7.774% annualised. December BTCUSD_261225 at 78,706.0 is +1.3947% over 101.0764 days, 5.036% annualised.
Funding 3.901% minus basis 7.774% is −387 basis points, against +195 on Monday. The two legs are read off different clocks — the funding print is set at 00:00 UTC, the basis is the 06:10 UTC snapshot — which is the same convention Monday’s +195bp was computed on, so the comparison is like for like even though neither number is instantaneous. Two things are worth saying about how extreme that is, and both need their series bound printed. This morning’s funding print is the 40th-lowest of the 200 eight-hourly prints Binance publishes, a window that opens at 16:00 UTC on 10 July 2026 — bottom quintile, but not a record. And the September basis is now above December’s, 7.774% against 5.036%, so the reversal is not simply a dated-contract move.
That matters for one of this desk’s open tests. G2 asks whether the September basis exceeds 8.00% on 25 September. Monday’s reading was 5.885%, 212 basis points short. This morning it is 7.774% — 23 basis points short. A test that was 212 basis points from its bar on Monday is now 23 basis points from it, and nothing about the spot price explains the move.
Positioning unwound with it
Open interest at 00:00 UTC on 15 September was 103,517.289 BTC, down 1,380.047 or 1.316% from Monday’s 104,897.336. The dollar figure of 8,092,805,674.63 implies a price of 78,178.30 against Bitstamp’s 14 September close of 78,185.01 — a gap of $6.71, or 0.0086%. The cross-check passes. Live open interest at 06:10 had rebuilt to 104,319.061, up 801.772 from the daily print.
Two account-ratio series fell hard. Binance’s global long/short account ratio went 1.6631 to 1.1631. The top-trader position ratio, which on Monday printed 2.3265 — the highest of the thirty daily readings Binance publishes, a window opening 17 August — fell to 2.0637. That drop of 0.2628 is the largest one-session fall in those same thirty readings; the largest one-session rise in the window was +0.2391 on 22 August. The 30-day high in top-trader positioning lasted exactly one day.
So the honest reading of Monday-into-Tuesday is not “leverage built” or “leverage flushed”. It is that a crowded long in the perpetual was paid for one session at almost 9% annualised and then materially reduced, while the dated September contract richened. Whoever is still long is now long the cheaper instrument.
For the mechanics of reading these three series together, this desk’s standing references are Field Guide #37 on telling a cash-bought rally from a leveraged one and the guide to open interest, funding and liquidations.
Price: a 1.79% session, and it did not hold overnight
Bitstamp BTC/USD for Monday 14 September: open 76,804.19, high 79,579.16, low 76,370.36, close 78,185.01, up 1.792%, volume 2,451.21. The 3,208.80 range is the 56th-widest of the 257 completed sessions of 2026. On the base of the 31 December 2025 close of 87,496, 2026 now stands at 125 advances and 132 declines — advances moved 124 to 125, and the provenance check against Monday’s published tally passes.
Month to date the market is −0.491% from the 31 August close of 78,571.17; year to date −10.642%. Tuesday’s partial session at 06:10 UTC: open 78,185.01, high 78,241.56, low 77,292.20, last 77,645.07, down 0.691% on volume of 316.18. Binance’s BTCUSDT perpetual last printed 77,654.00 on 24-hour quote volume of $1.109bn.
L1 asks for a Bitstamp close at or above 81,265 on Wednesday. From 78,185.01 that needs +3.939% in one session. Strategy’s 4,603-coin tranche at 80,318 is $2,132.99 per coin underwater at Monday’s close, a mark-to-market of −$9.818m, improved by $6.335m from the −$16.153m it carried at Sunday 13 September’s close of 76,808.69.
Z1 grades a FAIL
Z1 asked whether a Strategy 8-K would show at least one bitcoin bought by today. The filing of record, dated 14 September and covering the week ended 13 September, reports that the company bought and sold no bitcoin — the second consecutive week at zero — while repurchasing 1,420,467 shares of its variable-rate Series A perpetual STRC preferred for approximately $139.3m. Holdings are reported at 845,050 BTC and $6.4bn of USD assets as of 13 September (StockTitan, 14 September; The Crypto Times, 14 September).
Z1 therefore grades a FAIL on the filing of record. The marker’s window runs to the end of today, so a filing later on 15 September would change it; this desk will note it here tomorrow if one lands. The capital-allocation arithmetic gets its own treatment in today’s update.
Flows, sentiment, mining, sidechain
- ETF (Farside). The 14 September row is partial: MSBT +9.7 is the only fund reported, every other column is a dash, and the row total reads 9.7. Taking it as printed, September is +317.0 across 9 sessions with 12 reporting sessions left in the month, which keeps H2 open. The four-session run to 11 September was −462.7.
- Fear & Greed. 61 on 13 Sep, 57 on 14 Sep, 69 today. That +12 is the largest one-day rise in the fifteen readings pulled this morning, a window opening 1 September. Two days of decline were erased in one.
- Mining. Tip 967,083. The epoch is 70.39% through with 597 blocks to the retarget at height 967,680, projecting +4.901% against Monday’s +4.485% and Friday’s +3.10%. The previous retarget was +1.307%. Estimated retarget 19 September, around 05:04 UTC.
- Liquid. Tip 4,058,062, up 1,429 on the session. The four stored heights re-verified identical for the fifth consecutive day — no second rollback. The peg-out address reads 3,601.47207156 BTC across 597 transactions, identical to the satoshi for the third consecutive morning, or 85.6474% of 4,205. T1 failed on Sunday and stays failed.
The two votes, and what is actually being decided
Today’s 14:15 Eastern vote is cloture, not passage — a procedural motion to open debate that needs 60 of 100. The Senate is 53 Republicans, 45 Democrats and 2 independents. On the widely reported expectation that Senators Paul and Hawley defect, 53 minus 2 is 51, so nine Democratic crossovers are needed, ten if Senator Tillis also goes. That arithmetic is this desk’s, done from the seat counts and the reported defections; 24/7 Wall St. published the same nine-vote figure on 13 September. Punchbowl News reported on 14 September that Democrats were describing the cloture vote as doomed; CryptoSlate reported on 14 September that the final deal was breaking down hours before the vote. Cloture failing does not amend the bill — it shelves it.
Wednesday’s Fed decision carries the quarterly Summary of Economic Projections. Market-implied odds of a hike have been quoted across a wide range in the past week and this desk prints the spread rather than resolving it: roughly 56% on a CME FedWatch reading carried by Yahoo Finance, 85.4% in Bitcoin News Digest’s 13 September edition, and 79.5% on Polymarket when this desk checked on Sunday 13 September. J.P. Morgan Wealth Management expects a 25 basis-point hike; Goldman Sachs calls a September hike very unlikely. The June dot plot had nine participants projecting at least one hike this year, six projecting more than one. The current target range is 3.50–3.75%. AF1 asks whether the committee raises it.

Of the 24 markers this desk was carrying into today, Z1 closes, taking the count to 23; the four new tests set across today’s package — AM1 and AN1 in the news article, AO1 and AP1 above — take it to 27. The 21 rows above are those that bear on today; the remainder are carried. AE1, AG1, AI1 and AJ1 all settle at 00:00 UTC on Wednesday and none of them is graded here: a marker is graded on its settlement date, which is a rule this desk broke on Sunday and does not intend to break again.
Elsewhere in today’s package: the LEAF marketplace produced its first observable prices overnight, and they came with a commission of exactly three per cent — the seven settlements, in full. Monday’s board is here; the SGX thread that AL1 tracks is here.
Method: prices, funding, open interest, basis, mining and on-chain figures in this article are pulled directly by Bitcoin Mastery at the timestamp stated — Bitstamp BTC/USD daily candles for closes, Binance BTCUSDT spot and USDT-margined perpetual for intraday, open interest, funding and account ratios, Binance COIN-M quarterly contracts for basis, mempool.space for difficulty, hashrate, address balances and individual Bitcoin transactions, blockstream.info’s Liquid API for sidechain block heights, hashes, timestamps and transaction counts, alternative.me for the Fear & Greed series and Farside Investors’ table for ETF flows. Transaction counts, fee totals, byte totals and OP_RETURN payloads are recomputed from the full confirmed transaction list of the address concerned, not read off a summary. Where a third-party figure is cited we name the source and its date; where two sources disagree we print both. Every streak or extreme figure is published with the first date of its series in the same sentence. Where a figure published by this desk on an earlier date is superseded by a recount, the correction is printed in the article that supersedes it.
