(KANSAS CITY, MO) — A sharp escalation in the Russia-Ukraine war — headlined by the closing of the Kerch Strait — sent the wheat complex flying higher and dragged corn and soybeans along with it on Wednesday. And two analysts who joined Wednesday’s episode of Market Talk, Mike Zuzolo of Global Commodity Analytics and Chip Nellinger of Blue Reef Agri-Marketing, described a market that had been primed to move for weeks, and funds caught badly on the wrong side of it.
A wheat market “ripe” for a rally
Nellinger said the setup was there long before the headlines hit. “I thought wheat was a ticking time bomb even ahead of this news,” he said, pointing to funds content to sit on a 60,000 to 70,000 contract net-short position — even after one of the worst wheat harvests the Plains have seen in years. For much of the war, he noted, there had been “almost an unwritten agreement” that neither side would breach global food security, leaving most grain terminals and transport lines open. That changed over roughly 36 hours.
With reports of well over 100 vessels struck, the main channel Russia uses to move grain into the Black Sea closed, and insurance rates through the roof, Nellinger said the region is effectively shut for Russian and Ukrainian grain exports. The funds, he added, “got caught flat-footed,” and unwinding that short won’t happen in a single session: “One day is not enough time to get the funds out of their short position. This could be a several-day process here.”
Zuzolo framed the Kerch Strait as an entirely new pressure point on the map. Ukraine has said roughly 130 to 140 Russian vessels have been attacked since the start of July and the blockade now stacks a fresh bottleneck onto the two commodities he’s tracked closely for seven months: wheat and crude oil.
Reuters reporting this week put hard numbers behind the vessel strikes both analysts referenced. Drones from Ukraine’s Unmanned Systems Forces had targeted 116 vessels in the Sea of Azov over nine days — including five tankers, five bulk carriers and a tugboat — according to the unit’s commander, Major Robert Brovdi. The stated goal was to disable rather than sink the ships, crippling the “feeder fleet” of small and mid-sized tankers Russia uses to move oil out to larger vessels waiting in the Black Sea. Industry sources told Reuters that commercial ships could still move within the Sea of Azov but could not exit through the Kerch Strait, and the shipping restrictions helped send Euronext wheat up as much as 4% to a six-week high. With the sea carrying roughly a quarter of Russia’s grain exports, Moscow — the world’s largest wheat exporter — had not formally announced the curbs and accused Kyiv of terrorism, with Foreign Minister Sergei Lavrov saying the campaign “goes beyond even piracy.” A Ukrainian military source told Reuters its forces strike only military targets.
Energy: the other side of the strait
That crude connection is where Zuzolo spent much of his analysis. Russian refining of diesel, heating oil and gasoline hit a 21-year low last month, hammered by drone strikes on refineries and attacks on cargo ships in the Sea of Azov. With Russia among the world’s top diesel exporters and its number-one wheat exporter, the two markets have moved together — the WTI-to-soft-red-wheat correlation is back up to a 95% positive relationship on a four-week basis.
Zuzolo argued managed money has been “terribly caught on the wrong side,” having cut its net-long crude position from roughly 150,000 contracts down below 75,000 on a bet that supplies were returning. Now the market faces what he called a “double whammy” — the Strait of Hormuz blockaded again alongside the Kerch Strait — and he sees little reason funds won’t chase those old highs. His advice to clients came early: he’d recommended covering fall diesel needs even before either chokepoint tightened.
A weather market still in waiting
Both men stressed that the current rally is geopolitical, not yet a U.S. weather story. Zuzolo pointed to Europe as the real leader, with Paris wheat clearing 722 — its highest level since early 2024 — and Paris corn at 720 after the French government projected corn acreage down 13%. “It’s probably actually the leader in all the markets right now,” he said of the Paris board, “wheat, corn and beans.” The U.S. weather premium, he cautioned, could build quickly if a ridge of high pressure holds hot and dry into the first week of August.
Nellinger sees the domestic crop as workable but fragile. Corn is mostly tasseling and looks improved, but soybeans went into a shallow-rooted, immature stage just as 12 to 16 inches of June rain fell. “The next six weeks are going to be really critical,” he said. The bigger shift, in his view, is structural: after three or four years of an oversupplied market, “we are in a stocks-shrinking situation globally,” one that could support an early demand-led market for the next six to 12 months — and finally let wheat pull corn and beans higher instead of holding them back.
