The Strait of Hormuz has now been effectively shut to routine commercial shipping since 30 July, and on Monday at 2:00pm Eastern — 1800 GMT — US Treasury Secretary Scott Bessent will stand up at the Treasury Department and describe what he has called “the greatest co-ordinated economic isolation in the history of the world.” Bitcoin, which spent last week doing the single most violent thing it has done in two and a half years, spent the weekend giving some of it back.

As of 06:20 UTC on Sunday 23 August 2026, bitcoin traded at $76,172.24 on Binance. That is $3,327.76 below Friday’s intraday high of $79,500.00 — a drawdown of 4.19%, and 4.97% measured from that high to Sunday’s low of $75,545.67. Saturday closed at $77,074.93, down 1.61%. Sunday is running down again. These are the first two consecutive losing sessions of the entire move, and they arrive with roughly eighteen hours left on the weekly candle.

They also did something the wires have not noticed: they changed which record bitcoin is setting.

The headline changed category over the weekend, and this desk’s Saturday headline is part of the correction

On Saturday morning this desk published, and computed from its own Binance klines, that the week to date stood at +22.89% and that only nine weeks in the exchange’s history — which begins in August 2017 — had beaten it. The most recent of those nine opened on 13 March 2023 at +27.16%. Hence the headline: best week since March 2023.

Two down days later, the arithmetic has moved. With Monday’s open at $62,900.00 and the price at $76,172.24, the week stands at +21.10%. At that number, fifteen weeks out of 470 completed weeks beat it, and the most recent of those is the week opening 26 February 2024, at +22.01%. On the numbers as they stand this morning, this is the best week since February 2024, not March 2023.

The boundary between the two claims is a single price. To beat February 2024 and reclaim the March 2023 framing, bitcoin needs to close the week at or above $76,744.29. It is currently $572 below that. To beat March 2023 itself, it would need $79,983.64 — above Friday’s high, which is not happening. So the entire difference between two headlines that sound decades apart is about seven-tenths of one per cent of price, still moving, and settling tonight.

There is a third answer in circulation. Several wires have run “best five-day stretch since March 2024,” which is a different measurement entirely — a rolling five-session window rather than a calendar week — and it is not wrong, it is simply answering a different question. Three superlatives, three window conventions, one tape. We wrote a field guide on exactly this problem today, because the disagreement is not a rounding error: it is the difference between a two-and-a-half-year record and a six-month one.

Why Hormuz is the mainstream story and why it reaches bitcoin at all

The Strait of Hormuz has been closed to routine commercial traffic since the end of July, and the shipping data is stark. CNN’s vessel-tracking analysis put transits at roughly 20% of what they would have been before the war as of 18 August. Other trackers frame it more severely, counting daily commercial crossings in the low double digits against a pre-war baseline of around 130 a day. The two figures measure different vessel populations and should not be blended; take them as a range that says the same thing, which is that the world’s most important oil chokepoint is running at a fraction of capacity and has been for weeks.

Over the weekend Iranian state media said Tehran would allow Iraqi oil tankers through, after Iraq was forced to cut output sharply. Iran’s security chief Mohsen Rezaei threatened “earthquake-like” retaliation against further US action. A close ally of the supreme leader said Iran “will not submit.” None of that is a crypto story on its face.

Here is where it becomes one, and we are going to be careful about the claim. Bitcoin is not trading as a geopolitical hedge; this desk has said so in print repeatedly, including at the peak of last week’s enthusiasm, because the correlation record does not support it. The channel that actually runs from Hormuz to bitcoin is duller and much more reliable: closed strait → constrained crude → energy-led inflation → a Federal Reserve that cannot cut, and might have to hike → a discount rate that prices every long-duration asset, bitcoin included.

That channel is live right now. ICE Brent for October delivery settled at $94.39 on Friday 21 August, unchanged on the day and up more than 5% on the week. WTI for October settled at $87.06. US national pump prices are running above $4 a gallon, more than a dollar higher than a year ago. And the market’s September Fed pricing is no longer a debate about the size of a cut — it is a debate about whether there is a hike, with CME FedWatch and prediction markets clustered in the high twenties to low thirties in percentage terms as of the middle of last week.

What Monday actually contains

Bessent said on Thursday 20 August that Washington would impose “the toughest sanctions in history” on Iran and urged Beijing to co-operate; China said publicly that sanctions would not resolve the issue. Reuters reported the press conference is set for the Treasury Department at 2:00pm ET (1800 GMT) Monday 24 August. Analysts quoted by RFE/RL and Bloomberg expect the measures to reach beyond Iran itself and into the plumbing — Chinese banks, yuan-denominated oil payments, alternative payment rails, and the shipping, insurance and refining intermediaries that have kept Iranian barrels moving.

One nuance worth keeping straight, because it was mishandled widely last week: the frequently quoted figure that China buys around 80% of Iran’s crude exports is 2025 data. On 20 August Iran’s own central bank governor said exports have fallen to zero. The sanctions are therefore not primarily about stopping a flow; they are about keeping a flow at zero through secondary pressure on everyone who might restart it. Those are different policies with different market consequences.

Monday also brings two things that matter directly to this tape. Strategy’s next Form 8-K is due, its first purchase-or-sale disclosure since bitcoin crossed back above the company’s average cost. As of the 8-K filed 17 August, Strategy held 840,447 BTC at an aggregate cost of $63.36 billion and an average of $75,385 per coin. At $76,172.24 that position is worth $64.02 billion — roughly $662 million, or 1.04%, above cost. It spent most of the second quarter underwater. And Monday brings the first US spot-ETF flow print since the price high.

The ETF week, and the part of it nobody printed

US spot bitcoin ETFs took in $1,917.8 million across the five sessions from 17 to 21 August, on Farside Investors’ figures. BlackRock’s IBIT accounted for $1,330.8 million of it, or 69.4%. Wednesday 19 August produced $517.2 million and Thursday 20 August produced $606.3 million, the largest session since 1 May; IBIT’s $503.0 million on Thursday was its own largest day since 14 January.

The number the coverage settled on was the block total. The number that tells you more is what happened to everyone who is not BlackRock. Non-IBIT net flows ran $137.3m, $45.7m, $232.5m, $103.3m and $68.2m across the five days. From Wednesday’s peak to Friday, the rest of the complex fell 70.7%. IBIT over the same two days fell 15.9%. By Friday, IBIT was 77.8% of the entire day’s net flow, its highest concentration of the week, on the week’s smallest total.

A caution on the daily numbers you may see elsewhere: several summaries circulating this weekend carried Tuesday at $186.4 million and Thursday at $38.6 million. The Farside table says $189.3 million and $606.3 million. Check the source table before quoting a daily figure.

The rest of the tape, and the context most of last week’s coverage dropped

All three major US equity indexes finished last week lower. Friday itself was strong — the S&P 500 closed 7,674.37, up 0.43%; the Dow added 517.80 points to 53,277.01, up 0.98%; the Nasdaq Composite rose 0.44%; the VIX fell 5.5% to 15.13 — but Friday is not the week. Bitcoin’s 21% happened alongside an equity market that lost ground, which is a materially different story from “risk assets rallied together” and was the single most common framing error in last week’s coverage.

At the long end, the 30-year Treasury closed Friday at 5.276%, up 3.9 basis points, having opened at 5.247% and traded a 5.232–5.283% range. Its 2026 high is 5.34%, set on 18 August. The 10-year closed 4.736%. The dollar index sat at 98.839. Gold for December delivery settled at $4,680.60 on Friday, and the front-month gold contract’s own 2026 high is $5,586.20 from 29 January — a contract high, not a spot all-time high, and the two are routinely and wrongly conflated.

Equity proxies for the trade all had a strong Friday: Strategy closed at $119.25 (+6.10%), Coinbase at $186.49 (+8.20%), IBIT at $43.68 (+6.02%), MARA at $11.26 (+0.99%).

Two settlements and one open question

Tonight’s weekly close is not only a headline generator. This desk carries a public marker — Z1 — requiring the weekly close to land at or above $73,025.15, which was the previous Thursday’s close. At $76,172.24 the cushion is 4.31%, down from 5.9% at Saturday’s press time. Two down days have eaten roughly a quarter of it.

The other settlement already happened. Bitcoin’s mining difficulty retargeted at block 963,648 at approximately 00:47 UTC this morning, moving from 127.48 trillion to 125.81 trillion, a cut of 1.312%. This desk had a marker on it — U2, requiring a settled retarget of zero or better — and it failed. The full post-mortem, including why our own projection had the wrong sign for two consecutive days, runs in today’s analysis piece.

Network hashrate has meanwhile recovered hard from last week’s trough. The three-day average ran 812.7, then 863.6, then 945.9 EH/s across Friday, Saturday and Sunday, against a Thursday reading of 782.1 EH/s. Instantaneous hashrate is 907.5 EH/s. That recovery is precisely why the difficulty cut came in shallower than the mid-week estimates and deeper than the third-party ones — more on that tomorrow, and today, in the analysis.

What to watch

Tonight at 23:59:59 UTC, the weekly close: above $76,744.29 and the March 2023 headline survives; below it and this was the best week since February 2024. Monday at 2:00pm ET, Bessent. Monday morning, Strategy’s 8-K. Monday afternoon, the first ETF row since the high — and the question is not whether it is positive but whether anyone other than BlackRock shows up. Wednesday at 8:30am ET, July PCE, the last inflation print before the September FOMC. Thursday to Saturday, Jackson Hole, with Kevin Warsh’s first keynote as chair on Friday.
