Daily Comment (september 21, 2026).

Daily Comment (september 21, 2026). by patrick fearon-hernandez, CFA, and thomas wash. [Posted: 9:30 AM ET] | PDF Its Comment today opens with an update on the war in Iran, where Iran-backed proxies have staged a new attack on Saudi Arabia. However, speculation that President Trump could meet with the Iranian president in New York this week has raised hopes for new talks, driving oil prices and bond yields lower. Confluence Investment Management LLC next review several other international and US developments that could affect the financial markets today, including another strong election result for the far right in Germany and a major new issue of junk bonds related to artificial intelligence. United States-Israel-Iran: Iran-backed Houthi rebels in Yemen yesterday staged an apparent missile attack on the main airport in Saudi Arabia's capital, hitting a jet fuel depot and setting it ablaze. The Houthis also reportedly attempted to target civilians and infrastructure in the Saudi cities of Baish, Taif, Farasan, and Yanbu, but the strikes were thwarted by Saudi air defenses. The attacks appear to be aimed at increasing the costs of the Iran war for US allies. In any case, the attacks threaten to further boost energy prices for the US and other countries around the world. * Separately, new analyses by Bloomberg and energy analytics firms show the war in Iran cut Middle Eastern diesel fuel exports by about 770,000 barrels per day in March through August versus the same period in 2025. In contrast, the war in Ukraine has cut Russian diesel exports by only about 350,000 bpd in the same time frame, suggesting a decline in Western diesel prices would be more dependent on peace in Iran than peace in Ukraine. * Meanwhile, reports over the weekend said Walmart and Costco are both experiencing shortages of motor oil due to the conflicts. Prices for synthetic motor oil have at least doubled over the last year, forcing Costco to implement purchase limits. * At the same time, President Trump reportedly said over the weekend that he's open to meeting the Iranian president at the United Nations General Assembly meeting this week in New York. That statement has helped push crude oil prices lower so far today, with near Brent futures currently trading at $100.97 per barrel, down 2.8%. Government bond yields are falling in tandem, with the yield on the 10-year Treasury note now at 4.952%. Germany: In elections for the state parliament of Mecklenburg-Vorpommern at the weekend, the far-right Alternative for Germany party (AfD) came in first with 38.2% of the vote, while the center-left Social Democratic Party came in second with 35.5%. In contrast, the center-right Christian Democratic Union, which rules at the national level under Chancellor Merz, got only 4.9% of the vote, shutting it out of the state legislature. * The result confirms that the AfD continues to garner support and remains on track to possibly gain power at the national level in the coming few years. As the AfD gains power, German policy would probably become more friendly to Russia and antagonistic to the European Union. It would also likely become more anti-immigration and more populist in economic and social policy. * In the near term, after a similar rout in the state of Saxony-Anhalt two weeks ago, the result in Mecklenburg-Vorpommern raises the chance of a leadership challenge to Merz. In turn, that could spark questions of political and policy stability that may be a negative for German stock and bond markets. United States-Russia-China: On Friday, President Trump signed a bill into law known as the "Lindsey O. Graham Sanctioning Russia and Iran Act of 2026," which authorizes and expands statutory sanctions, tariffs, and prohibitions on Russia and extends existing sanctions on Iran. The legislation, passed overwhelmingly by Congress last week, gives the president the authority to impose tariffs of up to 100% on the five biggest buyers of Russian oil and natural gas, along with other measures against Russia and Iran. * The law in theory puts China at risk of US sanctions, since it is a major buyer of Russian and Iranian oil. * Despite recent US moves to delay the application of other tariffs on China, the new law could potentially cause some tension when General Secretary Xi meets with President Trump at the White House later this week. Russia: In the weekend's parliamentary elections, preliminary results show the United Russia party that serves as President Putin's main source of support came in first with 355 of the 450 seats in the lower house of the legislature. As expected, "systemic opposition" parties that usually vote with the Kremlin won most of the remaining seats. Putin's authoritarian regime therefore looks set to continue for the time being. * Perhaps more important, many observers believe Putin could now authorize a special military draft to raise more troops for the war in Ukraine. * That prospect has already prompted many Russian men to flee the country, but recent reports suggest the Kremlin has tightened security along its borders to contain the exodus. China-Japan: New data shows China's August exports of rare-earth magnets to Japan were down 17.1% from the same month one year earlier. That's better than the 52.2% decline in the year to July, but it suggests Beijing is still trying to punish Japanese Prime Minister Takaichi for her statement last year about Japan being likely to respond militarily to any Chinese effort to take control of Taiwan by force. * Permanent magnets made with rare-earth minerals are an important input for modern electronics, industrial products, and defense goods. * China's continued clampdown on exports of the magnets has therefore been disruptive to Japanese companies in a range of industries. China-Philippines: Social media videos confirm that a Chinese coast guard ship on Friday rammed a Philippine fisheries department vessel trying to deliver subsidized fuel to local fishing boats in a disputed area of the South China Sea. The renewed tensions come after a period of relative quiet. A new round of aggressive Chinese tactics to chase Philippine vessels away from the disputed waters would raise the risk of conflict between Beijing and Manila, potentially putting pressure on the US to intervene. US Labor Market: The Wall Street Journal yesterday carried an article on how renowned organizational psychologist Adam Grant thinks artificial intelligence will change the skill set needed for professionals to get ahead. According to Grant, the prevalence of information with AI will make people's expertise less valuable, but it will put a higher value on judgment and interpersonal relations. For example, Grant recommends touching base more often by phone calls or personal meetings to get a better sense of trends and how the future will evolve. US Artificial Intelligence Industry: Japanese technology-investment giant SoftBank this week will reportedly price an $11 billion issue of high-yield bonds to help fund the third tranche of an investment in OpenAI expected to close next month. This would be one of the largest junk bond deals ever, highlighting the continued AI loan demand that is helping drive up global interest rates and further raising fears of excess investment.

Walmart shares rise while Kroger stock drops despite both retailers facing slower growth and margin pressure

Walmart shares rose between 11 and 14 September, whilst Kroger stock declined despite beating earnings. Jim Cramer noted the contrast, suggesting Walmart might gain margin advantages. Kroger cut its full-year identical sales growth guidance to 0.2%-0.8% from 1%-2%. Its Q2 identical sales growth dropped to 0.2% from 3.4% year-on-year, missing analyst estimates of 0.9%. Operating margin remained flat at 2.8%. Walmart's Q2 comparable sales grew 2.6%, outpacing Kroger but missing estimates of 3.7%. The company expects a $10 billion cost headwind from higher fuel prices in fiscal year 2027. Its advertising revenue grew 38%. Walmart trades at a forward P/E of 37 versus Kroger's 11.96. Cramer previously suggested selling Walmart due to high valuation.

Walmart adds marketplace data, deeper AI features to Scintilla insights platform.

Walmart adds marketplace data, deeper AI features to Scintilla insights platform. Walmart's first-party data platform for merchants and suppliers, Scintilla, is getting a big upgrade next year. As part of first-party data and analytics division Walmart Data Ventures' Inspire conference this week, the company announced several new Scintilla features coming next year, including access to marketplace data, customizable dashboards, custom alerts, a deeper version of its Marty agent for Scintilla, and a closer link between the Scintilla data platform and both the Scintilla In-Store supplier app and Walmart's replenishment systems. "We're having one consistent approach of working and collaborating with our suppliers, and eventually marketplace sellers, as well, giving them the full visibility so that we can actually push the right business or push the right experience to our customers wherever they are," Mark Hardy, head of Walmart Data Ventures, told Modern Retail. First-party Walmart suppliers who also sell on Walmart's marketplace will be able to see their marketplace data via Scintilla beginning next year. Hardy said by including marketplace data, Scintilla users will be able to see the full breadth of their Walmart.com business. Amit Dodeja, CMO of e-commerce accelerator Spreetail, said his team had been encouraging Walmart to open up more access to marketplace data as more proprietary data makes it easier for brands to understand what's working or not working in terms of advertising, pricing, etc. "It's a wise move for Walmart to head in that direction," Dodeja said. "It only strengthens the confidence that a third-party seller has on their platform." Scintilla is not yet available to those who solely sell on the Walmart marketplace, and there are no plans to make the platform available to them at this time, according to a Walmart spokesperson. The new dashboards will connect data sets together so users can see in the same place whether sales are growing or declining alongside how customer behaviors are changing and how the supply chain is behaving, such as if consumers are leaving the brand or if inventory isn't in the right place. Hardy said this "allows us now to provide visibility across all data sets, making individual data sets only relevant to subject-matter experts." The expanded AI functionality will allow Scintilla's Marty AI assistant to look across all data sets and alert users to help them understand what is happening in their business performance. Currently, AI within Scintilla is limited to use cases such as explaining what a metric means or the features and capabilities of Scintilla, or highlighting changes in a report, or summarizing findings, Hardy said. "What we're doing now is taking AI and moving from summarizing findings or highlighting key points to, now, [making] recommendations," Hardy said, adding that it may tell users why customers are lapsing and what they can do in areas such as supply chain or advertising to fix that. "It'll allow you now to... bring all those data points together and help you get to the conclusion of what you should do next." While not offering it to marketplace-only sellers quite yet, Walmart has been expanding access to Scintilla: Just last month, the company said it plans to expand the platform to Sam's Club suppliers in the U.S. next year. In February, Walmart launched Scintilla In-Store, a a new iteration of Volt, a platform acquired by Walmart in 2022, which gives supplier field representatives visibility to store-level data. Walmart CFO John David Rainey said on the company's second-quarter earnings call last month that Walmart Data Ventures "continues to drive meaningful growth," though the company doesn't disclose the division's revenue in its public financial statements. "Users value the platform's enhanced decision intelligence capabilities, which uncovered shared growth opportunities across Walmart's formats and markets." Correction: This story has been updated to clarify that sellers will only be able to see the full breadth of their Walmart.com customers via Scintilla next year, and they cannot see what all customers are purchasing at Walmart.

Senators seek review of Amazon AI origin claims: A seller evidence checklist.

Senators seek review of Amazon AI origin claims: A seller evidence checklist. September 18, 2026 Amazon What happened. On September 17, Senators Tammy Baldwin and Rick Scott called on the Federal Trade Commission to investigate Amazon and Walmart over alleged suppression of American-made products in AI shopping results and failures to address misleading origin labels. Their letter identifies Amazon's Alexa for Shopping and Walmart's Sparky, and cites a report alleging that the assistants could identify product-origin information but did not consistently surface it. These are the lawmakers' allegations and a request for investigation - not an FTC finding of wrongdoing. [1] For marketplace sellers, the immediate operational issue is narrower than the political debate: can each origin claim on a listing be supported, and does the customer see the same claim across text, images and product variations? What this does - and does not - change. The letter asks the FTC to investigate potential suppression and strengthen enforcement against false "Made in USA" claims. It does not announce a new Amazon seller requirement, a compliance deadline or a confirmed change to shopping rankings. Nor should the chatbot responses quoted in the letter be treated as independent proof of either company's internal motives or policies. [1] The underlying compliance standard already exists. FTC staff guidance says an unqualified "Made in USA" claim requires final assembly or processing in the United States, all significant processing there, and all or virtually all ingredients or components made and sourced there. Marketers need competent and reliable evidence, and must review their substantiation as sourcing changes. Qualified claims must also be truthful and supported; adding a qualification is not a universal safe harbor. [2] The guidance also distinguishes a U.S. brand or business address from a product-origin claim and warns that imagery can create an implied claim depending on the overall impression. Sellers should therefore assess the whole offer, not merely a country field. [2] Seller analysis: audit the claim before optimizing discovery. The following is its operational analysis, not an additional platform rule or legal advice. * Build a SKU-level evidence file. Record the manufacturer, production and assembly locations, relevant component information, supplier statements and the date reviewed. Do not substitute a supplier's U.S. mailing address for manufacturing evidence. * Check every customer-facing surface. Compare the title, bullets, description, image badges, packaging and variation-specific information. If one variation has a different supply chain, review it separately rather than inheriting a family-wide origin claim. * Separate service location from product origin. For computer and electronics sellers, describe local testing, configuration or support precisely when substantiated. Do not turn those services into a blanket statement that the underlying device was manufactured in the United States. * Correct unsupported language first. Pause disputed origin advertising while obtaining documentation and appropriate compliance review. Do not add patriotic badges or stronger claims merely to make an AI assistant recommend the item. * Test discovery with a reproducible log. Save the query, date, product identifier, answer and linked listing when an assistant gives contradictory information. Submit a focused correction request through the relevant platform channel. A screenshot helps document an output; it does not prove intentional suppression or guarantee a ranking remedy. The commercial takeaway. Treat origin accuracy and AI discoverability as separate workstreams. Evidence should determine what the seller can claim; observed search behavior should determine what needs testing or escalation. Combining the two into an attempt to "please the chatbot" risks making the listing less defensible without establishing any dependable sales benefit. The useful response to this week's request is an auditable catalog, not a speculative forecast of penalties, traffic losses or new platform restrictions.
