Daily Macro Brief
Hormuz tightens again while markets price only a limited shock
A weekend collapse in Hormuz traffic and the strike on Larak Island lifted energy and long-term rate pressure, but markets still do not reflect a systemic supply interruption.
This report is based on intraday data as of 11:52 AM ET and does not reflect closing prices. Markets may have moved since publication.
Review of Friday’s call
The August 28 brief argued that high rates were narrowing market breadth while AI platforms outperformed hardware. Long-term rates rose again today and broad indexes stayed weak, but NVDA and several hardware names beat the platforms after a new MediaTek catalyst. The rate constraint held. The leadership inside AI partly reversed, and the demand evidence still did not produce a synchronized move across the supply chain.
Today’s core view
The geopolitical evidence worsened over the weekend. Visible traffic through Hormuz contracted again, the United States struck launchers on Larak Island, and Iran claimed retaliatory attacks on American targets in the region. Markets are treating this as an energy and inflation shock rather than a systemic supply interruption. Crude oil and traditional energy companies rose, broad indexes slipped only modestly, and the dollar weakened. The harder problem is in bonds: the 30-year Treasury remains above 5%, the entire JGB curve moved higher, and global long-term rates have not yielded to uneven growth.
What matters today
Hormuz traffic fell again as the conflict moved closer to the shipping lane
Kpler reported Monday that visible commercial traffic over the weekend fell sharply from Friday and consisted mainly of smaller vessels. An inbound tanker was hit by an unidentified projectile near Khasab. The United States later struck Iranian launchers on Larak Island, saying Iranian forces were preparing to fire rockets carrying sea mines into the strait. Iran claimed attacks on targets in Jordan and the UAE, while the United States denied that any vessel had hit a mine in Hormuz.
The baseline has slipped from managed conflict with low traffic toward military activity closer to the shipping lane. Insurance terms, shipowners’ tolerance for risk, and LNG contract performance now matter more than official slogans. Treasury Secretary Scott Bessent also said more secondary sanctions were likely, initially with a focus on banks, but that was policy guidance rather than a new rule already in force. Continued weak traffic, more attacks, or extended force majeure declarations would transmit the shock from freight costs to physical supply and payment channels. Several consecutive days of higher traffic and the withdrawal of force majeure would weaken that case.
Chinese manufacturing improved at the margin, but construction and domestic demand still lag
China’s official manufacturing survey improved from July. Production, new orders, and export orders were on the expansion side, with large companies and high-tech manufacturers doing better. Overall manufacturing still sat just below the line between expansion and contraction. Nonmanufacturing showed no growth, and extreme weather weighed on construction.
The structure was better than the headline, but total demand remained soft. Better orders offer some relief to industrial companies, while stronger input and factory-gate prices leave more margin pressure with companies that have limited pricing power. The improvement will not become a broad domestic recovery unless smaller companies, consumer industries, and construction catch up. The next private-sector manufacturing survey and another month of new-order growth will show whether August was a starting point or monthly noise.
Texas manufacturing accelerated before the bond market saw a growth concession
The Dallas Fed’s August survey showed a clear acceleration in Texas manufacturing activity, new orders, capacity use, and business outlooks. Employment and wage pressure eased, but raw-material price pressure increased. The series also included its annual seasonal-factor revision, so one strong month should not be projected directly onto the national economy.
The survey at least weakens the claim that American industry is slowing in unison. It also gives the Federal Reserve less reason to focus only on downside growth risk. Higher raw-material costs arrived alongside renewed European energy inflation, giving long-term rates a reason to retain inflation compensation. If national manufacturing and employment data weaken next, Texas will look like a regional rebound. If orders and price pressure recur in other surveys, the hurdle for easier policy will rise.
Energy pushed European inflation higher again
Germany’s August inflation estimate accelerated from July while core inflation held steady, with energy doing most of the work. Early readings from Poland, Portugal, and Ireland moved in the same direction. Portugal’s statistics agency attributed almost all of its acceleration to fuel.
Energy is the main driver so far, and the evidence does not show broad overheating in core demand. The move still reduces the European Central Bank’s flexibility because households pay headline prices and wage negotiations can absorb an energy shock. If the euro-area release shows services and core inflation rising too, the rate constraint will become more severe. If the acceleration stays confined to energy, base effects could ease the policy pressure later.
Canada and the United States argued in public, but no new tariff schedule appeared
Canada’s chief negotiator, Janice Charette, rejected the American account of the talks and said Canada had always sought coverage for the entire auto industry. President Trump then told Canadian companies doing business in the United States to relocate south and again described Canada as a trade abuser. The window produced no new presidential proclamation, Section 338 rate revision, or Canadian tariff document.
The rhetoric can affect factory location, supplier contracts, and capital plans before a tariff takes effect, but it cannot replace legal text. Actual costs still depend on product coverage, exemptions, effective dates, and customs enforcement, any of which may differ from the political message. If the September measures take effect as planned, North American manufacturing and agriculture will absorb more friction. A verifiable agreement before implementation would leave mainly an uncertainty discount.
AI supplier relationships are regrouping around interconnect standards and model access
NVIDIA expanded its MediaTek partnership to cover custom XPUs that connect to NVLink rack systems, local AI devices, and automotive platforms, with financing through convertible bonds. Separately, OpenAI notified Cursor after SpaceX took control that it would end direct model supply. Anthropic then promised more computing capacity for Cursor. The OpenAI termination has a transition period, and the two sides are still talking.
The MediaTek agreement is a contest over which interconnect standard custom chips will use inside AI factories. The Cursor dispute exposes how model access can change with corporate control and terms of service. Both developments alter ecosystem boundaries, but neither is new earnings guidance. The industry effect becomes measurable if more XPU customers adopt NVLink or Cursor traffic moves materially toward Claude.
Prices provide the strongest counterevidence. Crude oil rose only modestly, the dollar weakened, and volatility remained low. Markets have not treated the strait events as a global supply break. The energy and inflation view needs to be downgraded if traffic recovers for several days, attacks stop, insurance and force majeure arrangements normalize, and long-term rates retreat. If shipping contracts further while oil remains calm, weak demand or substitute supply becomes the stronger explanation.
Bond market
The 30-year Treasury remains above 5%, and the 2-year JGB RSI reached 88.03, so today’s threshold table is warranted. The two snapshots were taken at different intraday times and indicate direction only. They are not a comparison of official closes.
| Market | Maturity | Aug. 31, 11:52 AM ET | Versus Aug. 28 intraday |
|---|---|---|---|
| U.S. Treasury | 2-year | 4.20% | about +1bp |
| U.S. Treasury | 10-year | 4.76% | about +4bp |
| U.S. Treasury | 30-year | 5.26% | about +5bp |
| Japanese government bond | 2-year | 1.719% | about +2.3bp |
| Japanese government bond | 10-year | 2.930% | about +3.3bp |
| Japanese government bond | 30-year | 4.084% | about +4.6bp |
The U.S. curve showed Bear Steepening. Faster Texas manufacturing, higher European energy inflation, and the Hormuz risk all call for more inflation and term compensation at the long end. The 2-year yield barely changed, so the market has not translated those shocks into a new Fed path. The 13-week and 26-week bill auctions drew bid-to-cover ratios of 2.77 and 2.63. Demand absorbed the supply without pulling the 30-year yield below 5%.
Japan’s curve moved higher more uniformly. July industrial output and retail sales beat expectations, and Bessent publicly said he expected the Japanese government and the Bank of Japan to take steps that would support the yen. That was neither a BOJ decision nor confirmation of currency intervention. The extreme 2-year JGB RSI describes strong recent rate momentum, not a guaranteed move at the next meeting. U.S. and Japanese long-term rates rising together shows that bond markets still demand compensation for fiscal, energy, and inflation risk.
Sectors and price response
As of 11:52 AM ET, VOO was down 0.4%, QQQ 0.2%, and MAGS 0.5%, while VIX rose 5.3% to 15.19. The dollar index fell 0.3%, TLT lost 0.8%, crude oil gained 2.5%, and BTC rose 1.2%. The adjustment was concentrated in energy and long-term rates. It had not become a broad Risk-Off move.
Energy and shipping
Crude oil traded at $85.50, up 2.5% intraday. XOM and CVX gained 1.44% and 1.50%, while OXY rose 0.62%, all better than the broad index. Lower Hormuz traffic and the Larak Island strike supplied a direct catalyst. Russia also extended export restrictions on diesel, marine fuel, and gas oils from direct producers, while the attack on the Kirishi refinery added uncertainty around refined products. President Trump said Venezuelan oil would replenish the SPR, but there was no contract, Energy Department operating document, or new inventory print. That statement cannot yet be counted as a physical inflow. If the next inventory reports remain comfortable and strait traffic recovers, today’s move will look like a short-lived risk premium. Simultaneous pressure on refined products and shipping would suggest that the energy response is still too small.
Chinese cyclical assets
FXI was flat intraday and copper rose 0.1%. Neither treated the official manufacturing improvement as a new growth cycle. That reaction fits the survey’s internal split: large and high-tech manufacturers were stronger, while smaller companies, construction, and nonmanufacturing remained weak. Copper was still up 3.6% over one month, so its recent trend was intact, but today’s calm offered no confirmation of faster demand. Private-sector surveys and physical orders need to improve before industrial metals can consistently beat the broader market. Otherwise, August will look more like a rebound from weather disruption.
AI semiconductors and platforms
SMH gained 0.2%, NVDA 1.15%, and DELL 1.55%, outperforming QQQ. GOOG, AMZN, and META fell 2.27%, 1.95%, and 1.04%. NVIDIA invested $3.5 billion in convertible bonds issued by MediaTek and expanded their NVLink work, giving custom XPUs and rack interconnect a company-specific catalyst. It did not lift the whole hardware chain. AVGO slipped 0.10% with an RSI of 24.9, and VRT lost 0.30%, leaving previously pressured infrastructure names without broad confirmation. The OpenAI and Cursor dispute could rearrange model distribution but has no measurable same-day effect on listed platform earnings yet. MediaTek customer adoption, Cursor traffic migration, and a common improvement in server and networking orders are the next tests.
Canada and agriculture
XIU fell 0.8%, underperforming the U.S. market and fitting the view that trade uncertainty still weighs on Canadian risk appetite. The agriculture group moved the other way. CF, NTR, and MOS gained 1.57%, 1.80%, and 2.35%. No new tariff list in the reporting window directly explains those gains. Higher oil and renewed European energy inflation may be relevant background, but they do not establish causation. NTR’s RSI reached 77.5, showing a stretched recent move rather than the reason for today’s gain. A September tariff list that covers fertilizers or important intermediates would test this divergence through costs and trade flows. If no list appears, the move looks more like independent relative strength in agriculture.
Digital assets
BTC traded at $78,606, up 1.2%, and retained a one-month gain of 25.1% with an RSI of 82.26. MSTR and COIN rose 2.02% and 2.21%, moving with the underlying asset. U.S. spot BTC ETFs recorded a $201.9 million net outflow on Friday, while spot ETH ETFs attracted $102.1 million. Strategy separately disclosed on Monday that its Bitcoin reserve had increased. A high RSI does not end a trend by itself, but it raises the need for fresh liquidity. Renewed and sustained ETF inflows, combined with sideways price consolidation, would let momentum cool without breaking the trend. Continued outflows would make the strength in the proxy names more fragile.
Power, uranium, and critical materials
CEG gained 0.75% and VST 0.19%, while NRG fell 1.39%. Power companies did not react uniformly to the AI partnership news. SRUUF rose 0.1% for the day and remained up 11.3% over one month, giving the fuel theme a steadier medium-term trend. Energy Fuels completed its acquisition of Australian Strategic Materials and brought the planned rare-earth magnet expansion at the Ochang plant in Korea into its business. The transaction integrates critical-material operations without directly changing same-day uranium spot supply or demand. Higher long-term rates still weigh on capital-intensive businesses, and the next evidence must come from project orders and long-term contracts. Without utility load guidance, nuclear fuel contracts, or magnet customer commitments, these themes can continue to move independently.
SPR update
President Trump said Sunday that Venezuelan oil would soon replenish the U.S. Strategic Petroleum Reserve. The reporting window contained no White House contract, Energy Department procurement or transfer document, or new EIA inventory print. The statement changes policy intent, not the confirmed physical balance. The next EIA report or a formal agency notice is needed to establish whether the replenishment process has started.
What to watch
China’s private-sector manufacturing PMI on Sept. 1, with timing to be confirmed by the publisher: watch whether new orders and exports confirm the marginal improvement in the official survey. Expansion in the private sample would make the August recovery more credible. Continued contraction would expose a wider split between large and small companies.
The euro area’s August HICP estimate at 5:00 AM ET on Sept. 1: watch whether the energy shock spreads into services and core prices. Broader inflation would further limit a decline in European rates. An energy-only acceleration would look more temporary.
The API report at about 4:30 PM ET on Sept. 1 and the EIA report at 10:30 AM ET on Sept. 2: watch for simultaneous tightening in commercial crude, gasoline, and distillates, as well as any actual change in the SPR. Comfortable inventories would weaken the transmission from Hormuz risk to prices. Draws across several products would amplify the shipping disruption.
The OPEC+ meeting on Sept. 6, with the exact time still unconfirmed: watch whether major producers change the planned supply path. Extra supply would cushion the Hormuz and Russian refined-product risks. An unchanged plan would keep attention on shipping, refinery operations, and inventories.
Canada’s planned countermeasures on Sept. 8: watch the final list, exemptions, customs documents, and any additional U.S. action. Measures taking effect on both sides would raise North American manufacturing costs. A verifiable agreement before implementation would narrow the current uncertainty discount.
The University of Michigan’s preliminary September survey at 10:00 AM ET on Sept. 11: watch whether consumer sentiment and long-term inflation expectations keep diverging. Weaker confidence alongside sticky inflation expectations would reinforce the difficult mix of slower growth and high rates.
