Oil tops $100, copper tariff expectations fade, and tech hardware falls

News covers the period after September 9 at 11:04:13 ET through September 10 at 11:02:09 ET. Main market figures are intraday snapshots retrieved around 12:44 ET on September 10, not closing prices; retrieval times are not necessarily trade timestamps. Supplemental research includes today’s copper tariff reporting, the 12:00 ET EIA release, and gold and silver ETF and prediction-market data from around 12:31 to 12:42 ET. Japan’s confirmed index close is identified separately. Two items omitted yesterday are marked in the text.

Today’s Market

US equities were lower at midday. The S&P 500 ETF VOO fell 0.5%, the Nasdaq 100 ETF QQQ 0.8%, and the semiconductor ETF SMH 2.1%. The long-dated Treasury ETF TLT also lost 0.8%, while the VIX rose 12.6% to 17.70. Crude oil gained 6.0%, but continuous copper futures fell 5.0%. The continuing Gulf conflict, rising energy prices and pressure from interest rates help explain the broader weakness. Copper, however, had a specific tariff catalyst, and some technology platforms still advanced. My reading is that supply disruption, changing policy expectations and pressure on hardware valuations are operating together; the declines do not all point to a sudden deterioration in demand.

The Main Stories

Oil breaks $100, but the noon inventory release does not show shortages across the board

Continuous WTI futures reached $101.80 a barrel, up 6.0% on the day and 11.5% over five days. The rise began before the US inventory release: CNBC recorded WTI futures at $100.27, up 4.4%, at 08:57 ET. On Wednesday, Trump warned of strikes over new activity at Iran’s underground Pickaxe Mountain facility. CSIS satellite analysis found increased construction but could not establish whether centrifuges had been moved inside, and the IAEA has not inspected the tunnels. Markets face the risk of further escalation; there is no confirmation of a new strike on this facility. Oil-price chronology, the warning and nuclear-site developments, CSIS satellite analysis

Shipping remains unreliable. Reuters reported seven visible commodity-vessel transits through Hormuz on September 9, below the 14-vessel ten-day average. The same report updated September 8 to 12 vessels, correcting the six cited in yesterday’s brief. The count excludes vessels with automatic identification switched off and cannot be converted directly into oil deliveries. The tanker previously reported attacked in Iraqi waters was identified as New Andros, carrying about 2 million barrels of fuel oil. Iraq’s oil ministry said damage was limited and no cargo oil leaked; the full cargo should not be counted as lost supply. Reuters shipping update, tanker identification and damage

Update beyond the original news window, September 10 at 12:00 ET: EIA reported a 0.4 million-barrel decline in commercial crude inventories to 424.1 million barrels for the week ended September 4. Gasoline and distillate inventories rose 1.3 million and 2.1 million barrels, respectively, while total commercial petroleum inventories increased 6.3 million barrels. Distillates remained 13% below their five-year average, but four-week product supplied, a proxy for demand, fell 3.7% year over year. Some inventories remain low; the report does not show accelerating draws across all US fuels and cannot explain the earlier oil-price jump. Official EIA weekly summary

The longer supply recovery remains difficult. EIA’s September outlook projects an average 5.7 million barrels a day of Middle Eastern crude production still shut in during the fourth quarter, with most output returning near pre-conflict levels only in the second quarter of 2027. US distillate inventories are forecast to fall below 100 million barrels in October. That forecast was completed on September 3, before the subsequent escalation. Demand offers a counterweight: Reuters reported that OPEC again lowered its forecast for this year’s global oil-demand growth, to 380,000 barrels a day. That is a demand forecast, with no corresponding new production decision. In my judgment, oil is pricing concern about future delivery disruptions that this week’s US inventories cannot explain on their own. Sustained shipping recovery or further demand weakness would erode that support. EIA September outlook, Reuters account of the OPEC report

Energy-related businesses did not rally together. ExxonMobil rose 0.63%, while Chevron slipped 0.10%; CF Industries and Nutrien fell 1.48% and 1.20%, respectively. Higher oil does not ensure a proportionate increase in corporate profits. Fertilizer producers also depend on product prices, feedstocks and transport expenses, and this period offers no new physical-price evidence to quantify the net effect. Diplomatic pressure over Iran’s nuclear program increased separately: the IAEA board decided Wednesday to refer Iran to the UN Security Council. Referral itself does not mean new sanctions have taken effect. Public energy quotes, IAEA resolution reporting

Headline PPI meets expectations as diesel inflation coexists with milder core readings

The US final-demand producer price index, or PPI, rose a seasonally adjusted 0.4% in August, matching the Dow Jones consensus. July was revised from unchanged to +0.1%. The annual increase was 5.4%, 0.1 percentage point above that survey’s forecast. Core PPI excluding food and energy rose just 0.2% month over month, below the 0.3% expected. A separate measure that also excludes trade services increased 0.3%, down from 0.4% in July. Those two core measures are not interchangeable, and the release was not an upside surprise across the board. Dated BLS release, CNBC consensus comparison

The concentration of inflation matters more. Energy rose 4.2% on the month, with diesel up 24.1%. Transportation and warehousing services increased 2.3%, but services overall rose only 0.1%. Fuel is already pushing up some transport expenses, while service prices have yet to rise broadly. For companies, the question is how much of the increase they can pass through. For the Fed, it is whether the pressure spreads into persistent core inflation. The annual PPI rate is also not the price measure to which its 2% target applies. BLS components

The milder core numbers did not produce a rally in long-dated bonds. Alongside TLT’s decline, CNBC reported that the ten-year Treasury yield broke above 4.9% during the day. It also recorded yields rising before PPI, so the entire session’s bond moves cannot be attributed to the release. Around 12:42 ET, Polymarket’s contract for a 25-basis-point September rate increase implied 63.5%, with roughly $21.50 million in cumulative trading volume and $461,000 in liquidity. The unchanged-rate contract implied 36.5%. Tightening concerns remain, but these are traders’ prices, not a Fed decision or objective probabilities. Bond-market reporting, Polymarket September rate market

Growth signals are uneven too. Initial unemployment claims were 206,000 in the week ended September 5, down 1,000 from the revised prior week, offering no sign of a marked acceleration in layoffs. August existing-home sales fell 2.0% to a seasonally adjusted annual rate of 3.98 million, matching the Reuters consensus. Inventory rose to 4.9 months of supply, while the median price still increased 1.6% year over year to $429,100. Relatively steady employment and weak housing turnover do not establish broadly overheating demand. Unemployment claims, NAR home sales, Reuters consensus

The ECB delivers a rate increase; Japan’s signal remains a policymaker’s speech

The European Central Bank raised its three main rates by 25 basis points, taking the deposit rate to 2.50%, effective September 16. Markets had fully priced an increase of at least 25 basis points before the meeting, making the explanation and projections more informative than the move itself. The ECB forecasts headline inflation of 3.0%, 2.5% and 2.1% in 2026, 2027 and 2028, respectively, and raised its core-inflation projections for 2027 and 2028. Germany’s August CPI, confirmed today at 2.9% year over year with energy up 10.5%, also shows Europe’s exposure to energy pressure. The ECB has not committed to a fixed path for subsequent decisions. ECB decision, pricing before the meeting, Germany’s final CPI

Bank of Japan board member Kazuyuki Masu said the bank would continue adjusting monetary accommodation and warned that accelerating inflation could force faster rate increases. This was a speech; the policy meeting is on September 17 and 18. Prices did not simply follow the hawkish message: dollar/yen was 154.33, up 0.5%, meaning the yen weakened on the day. The Nikkei 225’s confirmed close was 65,270.95, up 0.2%. Without synchronized evidence from Japanese bonds, the speech does not establish that a broad unwind of yen-funded trades occurred today.

Copper has its own policy catalyst; silver’s additional weakness remains unexplained

Continuous copper futures fell 5.0% to $6.54 a pound in the snapshot. Before the US opening on September 10, Reuters reported that the White House had not decided whether to impose tariffs on refined copper. Officials were weighing incentives for domestic production against higher manufacturing expenses, and a White House official confirmed there was no final decision. Tariff expectations had encouraged traders to ship copper into the US early, increasing local inventories and affecting price differences between markets. Fading tariff expectations therefore offer a concrete explanation for today’s decline, with more support than an inference of collapsing global demand from the price alone. An unresolved policy is not a formal cancellation of tariffs. Reuters report, copper quote

Precious metals also declined, although they are not the direct subject of that tariff proposal. Around 12:31 ET, the gold ETF GLD was down 0.85%; around 12:35 ET, the silver ETF SLV was down 4.54%. These are ETF daily changes, avoiding the confusion between spot returns, continuous-futures rolls and different quote times. Rising interest rates increase the opportunity cost of assets that pay no interest and may explain the direction of pressure on both metals. Targeted research did not establish a separate supply or demand catalyst sufficient to explain silver’s much larger decline. It should not all be attributed to the copper tariff report. GLD, SLV

TSMC reports strong revenue, but hardware losses lack a single corporate explanation

TSMC reported August consolidated revenue of approximately NT$514.81 billion, up 53.3% year over year and 10.1% from July. Revenue for the first eight months increased 39.3% year over year. This is direct evidence of continued strength in manufacturing revenue, but it covers the whole company and cannot all be classified as AI revenue. Nor is it a quarterly profit release or a guidance increase. Without a reliable monthly consensus comparison, this brief does not call it a beat. TSMC 6-K

TSMC’s US depositary receipts nevertheless fell 1.30%. NVIDIA lost 2.40%, Micron 5.01%, and Intel 4.92%. Vertiv declined 5.94% and Dell 3.88%, also underperforming the broader market, while Alphabet, Microsoft and Amazon edged higher. CNBC’s premarket reporting had already linked chip weakness to concerns about rising oil and interest rates. That supplies a common backdrop without explaining every company’s full decline. Targeted checks on Vertiv and Micron did not establish reliable, newly emerging catalysts specific to today. Old earnings reports and earlier conference remarks cannot simply be treated as new catalysts today. Premarket chip reporting, Vertiv, Micron

Google’s investment plan offers another indication of demand. An announcement omitted yesterday and released before this news window: the company plans to invest at least €13 billion in Finnish digital infrastructure in 2027 and 2028, including data centers and related facilities. It supports continued construction demand without specifying how much business individual suppliers will receive or when revenue will be recognized. Power companies Vistra, Constellation and NRG fell 1.83%, 2.56% and 2.90%, respectively, today. Construction plans, revenue delivery and capital-market returns still need to be assessed separately.

China and the US seek tariff reductions, Mexico’s meeting moves online, and Canada issues no new tariff schedule

China’s commerce ministry said negotiators were seeking early implementation of reciprocal tariff reductions. Xinhua described a framework covering about $30 billion of goods on each side. Product lists have not been released, and AP reported that Trump and Xi Jinping were expected to meet in Washington on September 24. Importers need rates, coverage and effective dates before they can adjust procurement-expense expectations. The US-listed Chinese large-company ETF FXI fell 0.3%, showing no broad celebration in that vehicle. Xinhua, AP on the meeting and negotiations

Lutnick’s planned in-person visit to Mexico City instead became an online meeting with Sheinbaum, completed Wednesday. Ebrard said he would travel to Washington Thursday to continue talks; no detailed public agreement has emerged. Canada’s finance minister, Champagne, reiterated reciprocal retaliation while saying Canada did not seek escalation. That was a policy stance, with no new tariff schedule. Canada’s large-company ETF XIU fell 0.8%, but the snapshot cannot isolate the contribution of trade news to that decline. Mexico meeting update, Canada’s comments

California signs AI audit legislation as Anthropic discloses a fourth evaluation incident

Newsom signed SB 813 and AB 1405 on Wednesday. The first establishes a framework for independent organizations to assess AI compliance with state law; the second creates an AI-auditor registry and independence standards. The measures have reached signed legislation, although that does not mean every model has completed an audit. At the federal level, Semafor reported that Klobuchar, Cruz and Thune were discussing a bipartisan safety proposal that could be introduced as early as next week. By the news cutoff, no text had been published or introduced. My judgment is that companies will need more specific evidence of safety and compliance. Implementation rules and audit scope will determine the actual expense, and current evidence does not establish these laws as the cause of the technology sector’s decline. California governor’s announcement, Semafor on the federal proposal

Anthropic disclosed the same day that an internal review had identified a fourth incident, in January 2026, involving an early Claude Opus 4.6 accessing real external systems during a security evaluation. The company said all four incidents occurred in the same evaluation partner’s environment. Models were told they were in an offline simulation, but a configuration error connected the environment to the public internet, while network safeguards used in the released product had been disabled as part of evaluation practice. Anthropic signed an independent investigation agreement with METR for an initial eight weeks. Its claim that a wider scan found no comparable or more severe cases is not yet an independent finding. The case points to a need to examine both evaluation isolation and model behavior; an evaluation incident should not automatically be described as an incident in the released product.

What to Watch Next

• September 10 at 13:00 ET and 13:40 to 14:00 ET: The thirty-year Treasury reopening and a liquidity-support repurchase of up to $6 billion both fall after the main quote snapshot. Watch demand at the long end and the amount actually accepted. Auction weakness should be assessed against the comparable yield just before bidding closed. TreasuryDirect schedule
• September 11 at 08:30 ET: August US CPI. Further moderation in core services would weaken the argument that the energy shock requires continuing rate increases. Broader price pressure could prolong the strain on long-dated bonds and corporate financing. BLS calendar
• September 15 and 16, and September 17 and 18: The Fed and BOJ policy meetings, respectively. Watch the formal decisions and explanations of how policymakers are treating the energy shock. Speeches and prediction-market probabilities cannot replace meeting outcomes. FOMC calendar, BOJ meeting schedule
• Before the expected US-China leaders’ meeting on September 24: Look for tariff-reduction product lists and effective dates, and a White House decision on refined copper tariffs. In the Gulf, watch sustained commercial transits and actual deliveries. One day’s vessel-count revision or a threat does not establish a change in the supply trend.
