Oil Settles Above $90 as the Iran Truce Expires — and Bitcoin Posts Its Best Day in Five Weeks

Brent crude settled at $90.87 a barrel on Monday, August 17, up 2.7% on the day, after the United States and Iran both ruled out extending the memorandum of understanding that ended June’s fighting — an agreement that expired on Monday. Speaking in the Oval Office, President Trump said he would not seek to extend the ceasefire. A senior Iranian official told Reuters that Tehran would shift to offence rather than rely on defence if diplomacy with Washington fails. Israel struck Lebanon over the weekend, killing 11 people in strikes on Saturday, August 15 and naming two Hezbollah commanders among the dead, with a further strike in Ansar on Sunday, per CNBC and regional reporting. Ship traffic through the Strait of Hormuz was at a near standstill: Kpler data reported via The National put Sunday’s transits at three, down from five on Saturday and twelve on Friday, while Reuters, also citing Kpler, reported zero commodity-vessel transits on Sunday. We cite both because they count different vessel classes; the ten-day average is around eleven ships, and roughly 520 vessels are reported waiting in the Gulf.

That is the day’s mainstream story, and it is a hawkish one for anyone who owns risk assets: higher energy prices feed directly into the inflation numbers a Federal Reserve with three hike-voting dissenters is already staring at. Here is the part that did not follow the script. Bitcoin rose 2.59% on Monday, from $62,900.00 to a daily close of $64,532.10 on Binance’s BTCUSDT pair, with a high of $64,610.01 (our own exchange pull). That is the largest single-day gain since July 14 — thirty-four days, or five weeks — and the highest daily close since August 9. As of 06:09 UTC on Tuesday bitcoin traded at $64,121, up 0.96% on 24 hours, market capitalisation $1.287 trillion (our own CoinGecko pull). Ether was at $1,892.15, down 0.33%, and Solana at $75.60. The whole complex sat near $2.28 trillion, with bitcoin dominance around 56.5%.

The bid arrived from a market that had just failed its weekly close. Sunday night’s candle settled at $62,900 — the lowest weekly close in seven weeks, and below the $63,220 line this column had circled in advance. Monday deleted that in a single session. The Crypto Fear & Greed Index moved with it, printing 41, “Fear” on Tuesday morning against 31 on Monday (our own alternative.me pulls) — a ten-point jump in twenty-four hours, one of the sharpest single-day moves in the index this month, and still not enough to leave the Fear band.

The hawkish half of the tape: New York factories at a four-year high

Oil was not Monday’s only inflationary headline. The New York Fed’s Empire State Manufacturing Survey printed a headline general business conditions index of 20.6 for August, against a median forecast of 11.0 and a Dow Jones consensus of 12 — roughly double expectations, five points above July’s 15.6, and the best reading in more than four years. New orders came in at 17.3, shipments at 11.7, and unfilled orders jumped eleven points to 15.5, per Crypto Briefing’s summary of the release. A backlog that is growing rather than clearing is the component that matters for prices; it is the classic early signature of pricing power returning to manufacturers.

On this desk’s reading, that is two independent inflation impulses landing on the same session — energy from the Gulf and goods from the factory floor — four weeks before a Federal Reserve decision that markets cannot price. September hike odds remain scattered across sources rather than converging: one futures-implied read has been quoted near 65%, another around 32.6%, and prediction-market contracts lower still. We print the dispersion rather than average it; when the providers disagree by more than thirty points, the average is the one number that is certainly wrong. Elsewhere on the board, gold futures settled near $4,418 on Monday, with spot quoted in a $4,366–$4,417 range, and traded higher again on Tuesday, WTI moved from $84.50 to $85.38, and the US 10-year yield sat near 4.70% (Yahoo Finance daily data, own pull).

Strategy raised $334 million and bought no bitcoin

Strategy filed its weekly 8-K on Monday and, for the first time in four weeks, it disclosed neither a purchase nor a sale of bitcoin. Holdings stand unchanged at 840,447 BTC at an average cost of $75,385. What the company did instead was sell 3.46 million MSTR common shares for roughly $333.7 million between August 10 and August 16, directing $132.2 million into repurchases of STRC preferred stock, $52.4 million to STRC dividends, and $149.1 million into its dollar reserve, which now stands at $4.8 billion (The Block, CoinDesk). The company has not disclosed a bitcoin purchase since June 22, when it bought 520 BTC for $34.9 million — a seven-week drought. MSTR closed at $97.68, up 4.99% from Friday’s $93.04. Today’s Update takes that filing apart line by line.

Treasury moved on the GENIUS Act — one day after we said the deadline had passed

On Monday the US Treasury issued its proposed rule implementing Section 3 of the GENIUS Act, opening a 60-day comment period that runs from publication in the Federal Register, per CoinDesk and Treasury. The rule is narrower than the headline suggests and more consequential than its length: it defines when a person issues a payment stablecoin in the United States, and when a token is offered or sold to a person in the country — the threshold question on which every subsequent licensing obligation depends. If adopted it takes effect on January 18, 2027, barring stablecoin issuance in the US without a federal or state licence; from July 18, 2028 it would stop exchanges, DEX interfaces, brokers, custodians and payment platforms from offering foreign-issued stablecoins unless the issuers comply with lawful orders and reciprocal arrangements. That second date is the one aimed squarely at offshore issuers.

We wrote yesterday that the GENIUS Act rulemaking had blown its statutory July 18 deadline with ten proposed rules and none finalised, and that the practical consequence was that the January 18, 2027 statutory backstop now governs the calendar — a missed deadline creating a harder date rather than a softer one. Monday’s proposal is that logic in motion: Treasury is now working backwards from January 18, and a 60-day comment window started on August 17 leaves very little slack for a final rule, a review period and an effective date. Bessent’s presence at Wednesday’s roundtable is the nearest thing to a live read on whether that timetable holds.

Elsewhere on the tape: CoinDesk reported that losses from the Coldcard incident have been traced to a years-old code bug, with roughly $100 million now attributed to it — a figure that has been range-cited across sources since the first reports and which we continue to treat as unsettled. And the Senate’s CLARITY Act cloture vote remains fixed for 2:15 p.m. ET on September 15, which is the legislative backdrop to every executive-branch move described above: the White House is convening a roundtable precisely because Congress has not moved.

Wednesday: two Washington events, thirty minutes apart

• • Wednesday, August 19, 2:00 p.m. ET — FOMC minutes. The full account of the July 28–29 meeting, at which the Committee held the target range at 3.50–3.75% on a fractured 9–3 vote, with Beth Hammack, Neel Kashkari and Lorie Logan dissenting in favour of a quarter-point increase — the first time since September 2016 that three dissents have all pointed the same direction. Today’s Guide is a field manual for reading the document.
  • Wednesday, August 19, 2:30 p.m. ET — White House crypto roundtable. At the Eisenhower Executive Office Building, CFTC Chair Mike Selig and SEC Chair Paul Atkins are both expected; reporting also places Treasury Secretary Scott Bessent and Commerce Secretary Howard Lutnick in the room, while President Trump’s own attendance was still unconfirmed in the announcements we have seen. The invitation list spans Coinbase, Ripple, Gemini, Robinhood, Polymarket, Kalshi, Kraken, Chainlink, a16z, Paradigm, the NYSE, Nasdaq, CME Group, ICE and the DTCC, per PYMNTS. The framing in Washington reporting is that the meeting is designed to move on rules while Congress remains stalled.
  • Thursday, August 20, 1:00–4:00 p.m. ET — the CFTC Innovation Advisory Committee convenes for the first time, publicly livestreamed, across three sessions on crypto-asset regulation, artificial intelligence and prediction markets. Its 35-member roster overlaps heavily with Wednesday’s guest list.
  • Approximately Saturday, August 22 — difficulty retarget at block 963,648. As of 06:09 UTC Tuesday the projection is +0.49% with 651 blocks to run (our own mempool.space pull). It was −0.28% at the same hour Monday and −1.63% on Sunday.
  • Ahead: core PCE on August 26; Jackson Hole August 27–29, with Chair Warsh’s first keynote on the morning of August 28 under the theme “Financial Innovation: Implications for Payments and Policy”; the CLARITY Act cloture vote on September 15; the next FOMC decision on September 16.

One number is still missing from this report, and we would rather say so than fill the gap. Monday’s spot bitcoin ETF flow had not been posted by the trackers at our press time. It matters more than usual: Friday closed a run of three consecutive red days and a week of −$389.7 million, the largest weekly withdrawal since June, when the complex shed a record $4.5 billion. A fourth red day would be the longest outflow streak since June and would sit strangely against a 2.59% rally; a positive print would say the ETF bid came back on the same session the oil price broke $90. We flagged this test yesterday and we will report it either way tomorrow.

Why did Brent crude settle above $90 on August 17, 2026?

Brent settled at $90.87, up 2.7%, after the United States and Iran both ruled out extending the memorandum of understanding signed in June, which expired on Monday, August 17. President Trump said in the Oval Office that he would not seek an extension, a senior Iranian official told Reuters that Tehran would move to offence if diplomacy fails, Israel struck Lebanon, and Hormuz transits fell to three vessels on Sunday against a five-day average of twelve.

How much did bitcoin gain on August 17, 2026?

Bitcoin rose 2.59%, from $62,900.00 to a daily close of $64,532.10 on Binance BTCUSDT, with a session high of $64,610.01. That is its largest single-day gain since July 14, 2026, and its highest daily close since August 9.

What was the Empire State Manufacturing Index for August 2026?

The headline general business conditions index printed 20.6, against a median forecast of 11.0 and a prior reading of 15.6 — the strongest level in more than four years. New orders were 17.3, shipments 11.7, and unfilled orders rose eleven points to 15.5.

What happens on Wednesday, August 19, 2026?

The Federal Reserve publishes the minutes of its July 28–29 meeting at 2:00 p.m. ET, and the White House hosts a crypto and prediction-market roundtable at 2:30 p.m. ET at the Eisenhower Executive Office Building with President Trump, CFTC Chair Mike Selig, Treasury Secretary Bessent and Commerce Secretary Lutnick expected.

Did Strategy buy bitcoin last week?

No. Its August 17 filing disclosed no bitcoin purchases or sales for the August 10–16 period, leaving holdings unchanged at 840,447 BTC. The company instead sold about $333.7 million of common stock and used the proceeds for STRC preferred repurchases, STRC dividends and a $149.1 million addition to its dollar reserve, now $4.8 billion.
