Crypto surges, the yen weakens after a BOJ hike, and oil contracts need a closer look

The main news window runs from just after September 17 at 11:00 ET through September 18 at 11:00:05 ET. U.S. equities and related assets use intraday snapshots retrieved on September 18 between 12:56 and 12:58 ET, not closing prices. Retrieval times do not establish every series’ observation time. Additional midday reporting and prediction-market updates are identified below; daily government-bond series without confirmed observation dates are not used to assess today’s changes.

Today’s Market

U.S. equities have paused after yesterday’s rebound: the S&P 500 ETF VOO is down 0.2%, the Nasdaq 100 ETF QQQ is essentially flat, and the semiconductor ETF SMH is up 0.6%. The long-duration Treasury ETF TLT is down 0.7%, Canadian large-cap ETF XIU is down 0.6%, and U.S.-listed China large-cap ETF FXI is up 0.3%. Bitcoin is around $80,900, up 6.0% on the data source’s one-day measure, while Strategy and Coinbase have each gained more than 10%. Power producers, fertilizer companies and Netflix are noticeably weaker. Regulatory progress offers concrete support for crypto businesses, and alternative export routes help explain falling oil prices, but neither has produced a broad rally. The VIX is down 12.8% to 15.45, indicating lower implied volatility in S&P options rather than establishing the earnings outlook for every industry. VOO, QQQ, SMH, TLT, XIU, FXI, Bitcoin, VIX

Bitcoin returns above $80,000 as crypto businesses gain another regulatory route

Strategy is up 13.69% at midday and Coinbase 11.67%, far ahead of the broader market. An update outside the main news window: The Block’s September 18 report at 11:27 ET confirmed that Bitcoin had reclaimed $80,000 that morning, placing the rally alongside continued SEC and CFTC rulemaking. Bitcoin trades around the clock, so its one-day change and U.S. equities’ changes from the previous close do not measure identical periods. Strategy, Coinbase, The Block’s midday report

On September 17, the SEC issued conditional exemptions lasting five years, allowing eligible blockchain venues to trade tokenized U.S.-listed stocks and providing limited relief for associated liquidity providers. Tokens must carry the same rights as the corresponding shares. The framework limits securities and trading volumes, permits issuers to object to third-party tokenization, and requires trading to stop when the underlying stock is halted. The CFTC also expanded conditional no-action relief for software developers that day. The CLARITY bill’s setback in the Senate has not prevented agencies from using existing powers, although these measures do not replace the entire market-structure bill. SEC announcement, CFTC relief report

Fund flows have improved, with limits. U.S. spot Bitcoin ETFs recorded about $159.5 million of net inflows on September 17, ending two days of withdrawals. Across September 15 through 17, however, net outflows still totaled about $586.8 million. Ether ETFs lost another $39.3 million on Thursday. That supports an easing of pressure, but does not establish sustained inflows or Friday’s full-day result. September 17 ETF flows

My reading is that Coinbase’s business outlook may benefit from crypto prices, trading activity and the new regulatory route together, while Strategy responds more directly to the value of its Bitcoin assets. The evidence cannot isolate each factor’s contribution or establish a short squeeze. Coinbase’s banking-services partnership with Stablecore offers another commercial route, but Stablecore’s distribution network reaching more than 3,000 institutions does not mean all those institutions have already connected to Coinbase. Banking partnership, first reported September 16

Saudi alternative exports weigh on oil, while the $96 quote also reflects a contract issue

On September 18, Reuters cited several trading sources saying Saudi Arabia had sold about 60 million barrels for September and October, moving crude from Ras Tanura through ship-to-ship transfers near Sohar, Oman, primarily to Asian refiners including those in China and South Korea. The report estimated Saudi Gulf exports at about 1 million to 1.5 million barrels a day. Cumulative sales, daily exports and deliveries are different measures, and the company has not officially confirmed these quantities. Compared with earlier reporting of roughly 20 million barrels, the new information is the larger scale of the alternative route, which provides some relief for tight crude supply. Reuters transshipment report

Reuters-based reporting around 10:08 GMT, or 06:08 ET, put Brent at about $103.17 a barrel, down 1.6%, and WTI at about $101.30, down 0.6%, extending declines into a third day. The local midday snapshot instead shows continuous WTI futures at $96.13, with a source-reported daily change of -1.1%. Broker PrimeXBT explained that some continuous quotes had rolled from October to the cheaper November contract, with the two trading around $101.3 and $96.6 at the time. Subtracting the midday $96 quote from the morning $101 quote would therefore misrepresent the move as a five-dollar plunge in one contract. These are neither spot prices nor final settlements.

ExxonMobil, Chevron and Occidental are down 0.36%, 0.38% and 0.73%, respectively, consistent with lower crude selling prices weighing on producers’ revenue. Shipping remains risky: at least two vessel attacks were reported in Hormuz during the window, and vessel identities have not been fully reconciled with Iranian claims. At least two liquefied natural gas (LNG) vessels completed passages this week, still far short of the prewar pace of roughly three a day. There is also no consistently supported timetable for full restoration of the East-West pipeline. More alternative transport can reduce the risk premium without establishing that shipping has returned to normal. ExxonMobil, Chevron, Occidental, Vessel-attack reports, Bloomberg/Kpler LNG reporting

Europe still faces a winter gas-supply gap. Reporting citing GIE puts EU storage at 68.7% on September 16, below the five-year seasonal average of about 88%. Slow maritime recovery means falling oil prices have not removed the pressure to replenish gas storage. European storage report

Inventories do not support a claim that official data confirmed a large crude build. The EIA’s September 16 release showed commercial crude stocks falling about 0.6 million barrels to 423.4 million barrels in the week ended September 11. The earlier 7.14 million-barrel build was an API estimate. Distillate inventories rose about 1.6 million barrels but remained 13% below their five-year seasonal average. Restrictions on U.S. diesel exports are still proposals under debate among officials, not supply measures already in force. EIA weekly summary, API estimate, Diesel-export debate

Japan raises rates to their highest since 1995, but the yen weakens

The Bank of Japan decided on September 18 to raise its policy rate 25 basis points to 1.25%, in a 7-2 vote. It was the next increase after June and took the rate to its highest since 1995. Markets had widely anticipated the move. Governor Kazuo Ueda did not commit to a fixed pace of increases at his press conference, saying subsequent decisions would depend on inflation risks. August core CPI, excluding fresh food, rose 1.7% from a year earlier, below both July’s reading and expectations of 1.8%. That distinction matters: current inflation and the future upside risks concerning the central bank are not the same thing. BOJ decision reporting, Reuters press-conference transcript, August CPI

CNBC recorded the yen weakening about 0.45% to 156.64 per dollar after the decision and the ten-year Japanese government-bond yield falling 4.9 basis points to 2.947%. The U.S. midday dollar-yen snapshot is 156.78, up about 0.5% on the day, still showing a weaker yen. The first figures are a post-decision market snapshot and should not be joined to Japanese bond series with unidentified observation dates. My reading is that an expected hike, dissenting votes and the absence of a commitment to consecutive increases supplied too little new information to strengthen the yen. That does not establish that the BOJ has finished tightening. CNBC post-decision market report, Dollar-yen

U.S. factory output weakens while financing pressure persists

At 09:15 ET, the Federal Reserve reported unchanged seasonally adjusted industrial production in August, below the 0.3% increase listed in public economic calendars and following 0.2% growth in July. Manufacturing output fell 0.3%, ending seven consecutive months of growth, while utilities output rose 1.8%, offsetting some factory weakness. Overall capacity utilization was 76.3%, or 3.1 percentage points below its long-run average. This is an August production report; the Fed’s rate increase two days ago cannot have caused that month’s outcome. Federal Reserve G.17 preliminary release, Expectations at release

The weak data have not coincided with a midday rally in long Treasuries: TLT is down 0.7%. Thursday’s $19 billion reopening of ten-year Treasury Inflation-Protected Securities (TIPS) cleared at a real yield of 2.653%, compared with 2.438% at the security’s original July auction, a difference of 21.5 basis points. It was the highest auction yield for this term since 2008. The real yield measures the required return beyond the bond’s inflation adjustment and must not be confused with a nominal Treasury yield. These observations show that weaker production and financing pressure can coexist, without establishing that today’s bond decline was caused by this release alone. Treasury auction results, Historical auction comparison

Reference outside the main window, updated around 12:58 ET on September 18: Polymarket’s October 25-basis-point hike contract implied a probability of about 56.5%, versus 43.5% for no change. Cumulative volume was about $1.66 million and $2.09 million, respectively, with liquidity of roughly $480,000 and $350,000. These trading prices still favor further tightening. They express market opinion, not a central-bank decision. Polymarket October rate market

AI construction and safety debates advance together, while hardware and power diverge

At midday, Broadcom is up 1.99%, Micron 1.69% and Vertiv 2.21%, while Nvidia has gained just 0.16%. Intel is down 1.80% and Dell 1.62%. Jensen Huang said publicly on Thursday that chip sales would double next year, a management statement rather than formal earnings guidance. Reports also continued circulating Thursday that Crux AI, Alphabet and Blackstone’s cloud venture, had secured about $22 billion in debt financing to acquire Google TPUs. Its first 500MW is targeted to come online in 2027; financing does not mean the facilities are operating. Alphabet is up 0.72% at midday. These business developments are consistent with parts of the market’s performance but cannot explain every move across the sector. Broadcom, Micron, Vertiv, Nvidia, Intel, Dell, Huang’s comments, Crux AI financing, first reported September 16, Alphabet

Intel’s talks with SK Hynix about U.S. memory production have not become a formal agreement. Leasing Ohio facilities or forming a joint venture remain undecided options. Today’s decline in Intel does not establish that the talks have broken down. SK Hynix’s explanation of the options

Power producers are more uniformly weak: Constellation is down 2.97%, Vistra 1.88% and NRG 1.93%, with five-day losses of 10.45%, 5.07% and 8.17%, respectively. Follow-up research did not identify a new contract cancellation or earnings announcement establishing a common catalyst for today’s declines. An article published today about Constellation cites Reaves’ second-quarter investor letter on the supply of shares issued for the Calpine acquisition. That explains an earlier quarter, not a new issuance today. Higher financing rates may weigh on these capital-intensive businesses’ valuations, but the specific daily attribution remains unclear. The declines do not establish that AI electricity demand has fallen. Constellation, Vistra, NRG, September 18 report on the second-quarter letter

AI safety news also contains developments worth considering separately. Hacktron researchers disclosed that, during authorized vulnerability testing in July, they used Claude to access an OpenAI employee’s account and a connected code repository, earning a $6,500 bounty. The vulnerabilities have been fixed; this is not an intrusion reported to be continuing today. More than 100 researchers also signed a letter released Friday demanding independent governance, protection from interference and adequate access for outside evaluators. Thursday’s industry meeting in Scotland produced no formal agreement to pause development, and Huang continued to favor self-regulation. Anthropic meanwhile said Claude performs roughly a quarter of the work developing its next model. Improved development efficiency and demands for stronger evaluation are advancing together, without evidence that these discussions translate directly into canceled computing orders.

A tariff announcement may be delayed; Russia-Iran sanctions still await a signature

Bloomberg reported on September 17, citing people familiar with the matter, that the U.S. plans to delay its excess-capacity investigation report and associated tariffs until after the September 24 Trump-Xi meeting. An additional tariff of 7.5% on China had previously been discussed, but final rates and arrangements remain uncertain. USTR and the White House did not respond. If confirmed, a delay would reduce the prospect of immediate escalation before the summit without removing tariff risk. FXI’s 0.3% midday gain is insufficient evidence that markets consider an agreement secured. Bloomberg report

Another policy process continues: a White House official said Thursday that Trump plans to sign the Russia-Iran sanctions bill passed by Congress, but it remained unsigned at 11:00 ET on September 18. Implementation details will determine the risks for energy trade and third countries’ exports. In the European Parliament on Thursday, Mark Carney welcomed deeper Canada-EU cooperation while explicitly ruling out a bid for full membership. Trump’s severe tariff threats against the EU were made Wednesday and should not be counted again as a new escalation today. Sanctions-bill status, Carney’s speech and the limits of cooperation

• Berkshire announced on September 18 that Warren Buffett became chairman emeritus immediately while remaining a director. Howard Buffett succeeded him as chairman, and Susan Decker remains lead independent director. This completes the planned board succession. Greg Abel became CEO at the start of the year, so today’s announcement is not another change of operating chief. Berkshire announcement and shareholder letter
• Netflix is down 4.42% at midday to about $71.98. Wells Fargo cut its rating from Equal Weight to Underweight and its target from $80 to $57, citing weaker engagement and the upcoming content slate. The decline had already begun before the open, consistent with the timing of the rating news. This is an analyst’s concern about revenue quality and profit, not a reduction in company earnings guidance. Premarket rating report, Netflix quote
• CF Industries, Nutrien and Mosaic are down 3.50%, 2.08% and 2.11%, respectively. Targeted research still did not establish a reliable common catalyst for the day. Tight sulfur supply chiefly raises phosphate input expenses, and reporting says Mosaic reduced operating rates at some U.S. plants by about 50%. That cannot be applied directly to nitrogen and potash. Rising fertilizer prices do not necessarily improve every producer’s profit, and falling share prices do not establish that shortages have ended.

• The European Commission formally proposed its EU Kids Act on Thursday. It would prohibit social-media accounts for children under 13, restrict 13- and 14-year-olds to accounts linked to a guardian, and extend protections to AI chatbots, video and gaming services. Maximum fines could reach 6% of annual global revenue. Platform design, age verification and auditing requirements remain legislative proposals, not rules already fully in effect.

• TSMC reportedly received approval for its Longtan expansion, planning three fabs for 1.4nm and smaller processes, with more than NT$1 trillion of investment and the first fab targeted for production around 2030. This concerns longer-term supply. Micron’s Taiwan union rejected its annual reward proposal and government mediation has begun, but there is no strike timetable and therefore no basis to treat it as a current production interruption.

• Uranium reporting requires a distinction between old and new information. Kazatomprom’s reduction in 2026 nominal production levels from 32,777 to 29,697 tonnes of uranium was disclosed in August 2025, not announced today. Its March release put 2026 actual production guidance at 27,500 to 29,000 tonnes of uranium, subject to sulfuric-acid availability. Company’s 2025 results release and disclosure timeline
• Military escalation remains a risk in the Middle East. Trump told Axios Thursday that he was weighing further attacks on Iran’s regime and would use meetings with Gulf leaders to inform his decision. Saudi Arabia and the Houthis continue exchanging attacks, keeping Red Sea routes under pressure. The U.S. approved a proposed sale of 48 F-35s to Saudi Arabia for about $24.3 billion, still subject to congressional review; the aircraft have not thereby been delivered.

• Independent UN investigators said there were grounds to believe U.S. strikes on a school in Minab and on Lamerd in Iran may constitute war crimes. This is an investigative conclusion, not a criminal court judgment. Russia and China separately vetoed a resolution extending the Iran sanctions monitoring panel’s mandate. Appointments to the panel had never been completed, and its mandate has now failed to gain renewal. UN investigation report, Security Council vote
• Poland’s Prime Minister Donald Tusk warned that Russia could conduct drone or rocket attacks disguised as accidents. Emmanuel Macron ordered a critical-infrastructure protection plan and will convene G7 energy discussions. Taiwan separately conducted its first joint live exercises involving multiple attack-drone types, ahead of the September 24 U.S.-China summit. These are distinct security developments; there is no evidence that they form one explanation for today’s asset-price moves. Polish warning, French response, Reuters on Taiwan’s exercises
• Japan’s National Police Agency and the FBI disclosed that North Korea-linked WaterPlum used fake recruitment to trick applicants into running malicious code, affecting more than 30,000 devices across over 100 countries and territories and stealing crypto-wallet credentials. It exposes a security risk in hiring processes and is distinct from authorized AI vulnerability testing. September 18 disclosure

What to Watch Next

• The coming days and next week’s meetings with Gulf leaders: whether Saudi transshipments become sustained loadings and deliveries, whether the East-West pipeline gets a verifiable restoration update, and whether fresh attacks offset improvements in alternative routes. Oil comparisons should continue to use the same delivery month.
• The next ETF flow releases and platform announcements: whether Thursday’s inflows persist and which venues actually begin operating under the SEC exemptions. Actual trading activity and revenue will provide a stronger test of today’s crypto-company rally.
• Around the September 24 U.S.-China summit: whether tariffs are formally delayed and how final rates and coverage are defined; separately, whether Russia-Iran sanctions are signed and how they are implemented. Diplomatic arrangements alone do not establish the final terms businesses will face.
• Further company disclosures: whether Intel and SK Hynix sign a concrete agreement, whether Micron’s labor mediation affects production, and whether power companies change projects, contracts or financing arrangements. New operating evidence will say more about AI construction progress than a single day’s price moves.
