September 8 – Geopolitical escalation remains in focus to start the short week, with stock futures pointing to a mixed open and WTI crude oil prices posting a fresh three-month high amid a ramp-up in fighting in both the Middle East and Black Sea. The VIX is up notably from its 2026 low posted on Friday but remains relatively muted as it trades above the 15.4 level. The dollar is quietly lower to start the day, hovering around 98.84 at the time of writing. Treasury yields are also quietly lower to start the day, with the sharpest declines seen at the long-end of the curve; 2-year yields are trading at 4.37%, 10-year yields at 4.77%, and 30-year yields at 5.225%. Nearby WTI pushed to its highest level in exactly three months earlier in the session but has since pulled back to trade near $92.90, up ~1.8% on the day, while nearby Brent pushed to its highest level since July 24th earlier in the session but has pulled back to trade near $97.50 at the time of writing, up only ~0.4%. The ags are widely mixed, with the biggest strength being seen in the wheat complex after weekend talks failed to produce any major results, which we’ll dive into in more depth below.

Over the weekend, Iran targeted U.S. warships involved in the ongoing blockade, with CENTCOM reporting no casualties or damage, which led the U.S. to retaliate by striking three Iranian tankers with one sinking and the other two reportedly being permanently disabled. As could be expected, this led to additional escalation, with Iran targeting multiple ships attempting to transit the Strait of Hormuz over the weekend and ramping up threats to energy infrastructure across the region. To start the week, most of the escalation directly between the U.S. and Iran has been in rhetoric and stated policy, not kinetic warfare, but the same can’t be said of the region as a whole.

In fact, perhaps the most notable escalation since Friday has been the uptick in fighting between Yemen’s Houthis and the Saudi-backed Yemeni government, with recent days seeing some of the heaviest fighting in this conflict in years. On the ground, the Houthis are pushing toward terrain that could improve their ability to threaten Bab al-Mandeb shipping, while the Saudi-backed government has responded with both ground counterattacks and sustained airstrikes. The escalations are rapidly spilling over the Saudi border, with a notable wave of Houthi attacks on Saudi soil being seen over the last 48 hours. Large-scale Houthi strikes were carried out at several Saudi energy targets, including the Jazan refinery, as well as at Abha and Najran, all of which are near the Saudi-Yemeni border. The Saudi Energy Ministry said the strikes had led to a temporary suspension of operations at the affected facilities, also reporting 73 people being injured across the country in these attacks. This will surely be met with retaliation from the Saudis, with officials stating: “we will take all necessary operational measures to deter the terrorist Houthi militia with the utmost resolve.” It’s hard to see this resulting in anything but escalation, forcing markets to keep a closer eye on commodity movement through the Red Sea, with the stalemate between the U.S. and Iran on the other side of the Arabian Peninsula continuing to simmer.

US mediators traveled to both Moscow and Kyiv over the weekend, attempting to restart negotiations between the two sides after more than four and a half years of war. The market's primary focus right now is when the flow of commodities through the Black Sea will fully resume, with major implications for both the ag and energy sectors. A 72-hour pause in strikes on each country's capitals was announced, but Russia meanwhile continued their bombardment of other Ukrainian regions, again maintaining pressure on the Black Sea port cities of Odesa and Mykolaiv, then immediately resumed striking Kyiv overnight once the pause had expired. On the other side, Ukraine over the weekend struck Russian refineries at Ryazan, Perm, and Tatarstan, with the heaviest damage thus far reported at Ryazan. U.S. officials deemed the talks "encouraging," but no major breakthroughs were achieved, with the two sides remaining far apart in their demands, though Ukrainian President Zelenskiy stated today that the U.S. delegation presented new “decent ideas” for talks. While anything outside of continued escalation can be viewed as a positive, expectations are for the war to continue at least into the winter, with Russia targeting electrical infrastructure in the lead up, keeping upward momentum behind the wheat complex.

As we enter the traditional season of peak import demand in the Mediterranean, that question of timing comes more into focus. The graphic below provides a look at the seasonality of wheat imports in North Africa and Turkey, broadly speaking the top destinations for Black Sea wheat. As can be seen, the region started 2026 off on a very typical note, with January through May all seeing monthly imports effectively in line with the previous five-year average, but that fell off sharply into June and July. I must clarify that some of the June/July figures are based on mirrored data reported by the exporting nations, as official trade figures have not been published for all of these countries, and no official August figures are yet available, but the point remains the same. The reality is that the loss of most wheat shipment via the Black Sea is already being felt by the traditional first wave of buyers. Big domestic crops have bought these nations some time, allowing them to not be forced to step forward as quickly as usual, but seeing the loss of Black Sea shipping extended into winter would likely necessitate supply being pulled from further away to meet demand. October and November are historically the strongest periods of import demand in the region, but Russian and Ukrainian supply remains largely cut off. Given the weak E.U. supply, the longer-term question is if and when this starts shifting more demand to the U.S., whose small crop this year complicates the picture. Furthermore, this is just a look at the wheat side—remember, the longer the disruptions to Black Sea commodity flow remain in place, the more this impact is felt in both the feed grains and edible oils, forcing the market to keep a close eye on the progress of these talks.

Risks to Soybean Pod Fill Mean More Amid Return of Chinese Demand

Record domestic crush for biofuel has quietly removed the export cushion that once absorbed a wave of Chinese buying. Mike Castle explains why the same purchase volume now tightens the U.S. balance sheet far harder than it did four years ago.
