Latest / The Commodities Economy with Fexingo: Oil, Gold, Wheat, and Raw Material Markets / Why Corn Is Surging While the Rest of Ag Stalls in June 2026
Transcript
- Lucas: Corn is up seven-point-seven percent over the last five trading days. That's not a typo. And it's happening while wheat is essentially flat, soybeans are only up about three percent, and the broader commodity complex — oil, gold, copper — is getting hammered. Luna: That's a pretty wild divergence. What's driving corn specifically when everything else seems to be selling off? Lucas: Let's start with the obvious: crude oil. WTI crude is down six percent in the same period. You'd think that would drag corn down too, since corn-based ethanol competes with gasoline. But it's not that simple. Luna: Because ethanol blending mandates don't care about the spot price of oil, right? Lucas: Exactly. The Renewable Fuel Standard requires a certain volume of ethanol to be blended into gasoline each year, regardless of whether oil is at seventy dollars or fifty. So when oil drops, the mandate doesn't change — and that actually creates a price floor for corn used in ethanol. Plus, the EPA just reaffirmed the 2026 blending targets last week, which gave the market some certainty. Luna: So corn has regulatory support that wheat and soybeans don't have. Lucas: That's part of it. But there's also a real supply story. The USDA's latest crop progress report showed that only sixty-seven percent of the corn crop is in good-to-excellent condition — that's down from seventy-two percent at the same point last year. We've had dry weather in parts of Iowa and Illinois during the关键的 pollination window. Luna: And the market is pricing in that risk before we get the actual yield data. Lucas: Right. Meanwhile, the export data has been strong. Weekly export sales for corn hit nearly two million metric tons last week — well above the pace needed to meet the USDA's forecast. China has been buying, and so has Mexico. That's a demand-side boost that wheat and soybeans just aren't seeing right now. Luna: Interesting. So corn is getting a tailwind from both supply concerns and solid demand. But let's talk about the broader context — oil down, gold down, the S&P 500 futures sinking this morning on the tech rout. Why is corn bucking the risk-off sentiment? Lucas: That's the key question. I think part of the answer is that corn is a real-economy commodity — it's used for food, feed, and fuel. It's not a macro hedge like gold or a global growth proxy like copper. So when the market is selling off because of a tech-led growth scare, corn might actually benefit if investors rotate out of equities and into hard assets that have a tangible use case. Luna: But isn't the U.S.-Iran peace deal supposed to be bearish for energy and by extension for corn? Lower oil prices mean lower gasoline prices, which could reduce the incentive for ethanol blending. Lucas: You'd think so, but the peace deal has actually introduced some uncertainty on the supply side for fertilizer. Iran is a major producer of urea and ammonia — key nitrogen fertilizers. If the deal leads to sanctions relief, Iranian fertilizer could flood the market and lower input costs for farmers. That's actually bullish for corn production margins, even if crude drops. Luna: So cheaper fertilizer could boost corn supply later, but right now the market is focused on the weather risk and the demand data. Lucas: Exactly. And there's a time lag. Fertilizer prices affect next year's planting decisions more than this year's crop. For now, the market is trading the here and now: dry weather, strong exports, and a supportive regulatory backdrop. Luna: I also want to bring in the inflation data. The May CPI came in at three-three-four, up from three-three-two-point-four-one in April. Core PCE is also creeping up. Does that matter for corn? Lucas: Indirectly, yes. Inflation means input costs — fuel, fertilizer, land — stay elevated. That supports higher corn prices because farmers need to cover those costs. But in the short term, the CPI data also keeps the Fed cautious, which means interest rates stay higher for longer. That's a headwind for all commodities because it strengthens the dollar and raises the opportunity cost of holding physical goods. Luna: So corn is winning despite a stronger dollar environment? That's impressive. Lucas: It is. The dollar index is up about a percent over the last week, and corn is still rallying. That tells you the fundamentals are overriding the macro headwinds. For wheat and soybeans, the fundamentals just aren't as compelling. Luna: Let's dig into those. Wheat is essentially flat — down zero-point-three percent on the week. What's going on there? Lucas: Wheat has its own dynamics. The winter wheat harvest is underway in the Southern Plains, and early yields have been better than expected. That's adding supply to the market. Plus, Russia is still exporting aggressively — they had another record wheat crop last year and they're not slowing down. So the global wheat balance is pretty comfortable. Luna: And soybeans? Up three percent, but that's modest compared to corn's seven-plus. Lucas: Soybeans are caught in between. They have some weather concerns too — dryness in parts of the Midwest — but the export story is weaker. China has been buying Brazilian soybeans instead of U.S. ones because Brazilian prices are cheaper. So the demand picture for U.S. soybeans is less robust than for corn. Luna: So corn is the standout in the ag complex. But can it last? We're still months away from harvest. Lucas: That's the million-dollar question. If the weather normalizes and we get rains in July, the supply scare fades and corn could give back those gains. But if the dryness persists, we could see the market start to price in a much tighter balance sheet. The USDA will update its acreage and stocks report on June thirtieth, so we'll get more clarity very soon. Luna: I'm also watching the energy side. If oil continues to slide, eventually that could pressure ethanol margins and reduce demand for corn. But as you said, the mandate provides a floor. Lucas: Right. And look, the five-day drop in crude is partly driven by the Iran deal and the broader risk-off sentiment, but global oil demand is still growing. The IEA is projecting record demand this year. So I don't think oil is in a freefall — it's more of a correction. That means the ethanol floor should hold. Luna: So the corn rally feels fairly supported, but not immune to a shift in weather or policy. Lucas: Exactly. And that's what makes commodities interesting — they're always a mix of supply, demand, macro, and policy. Corn is the one that's lined up all four in its favor this week. Luna: Honestly, if walking through the economy with us has made something click — if the corn-ethanol connection or the Iran-fertilizer angle was new to you — that kind of clarity is exactly why we keep this show ad-free. It's a choice, and it's only possible because of listeners who chip in. Lucas: Yeah, it's a tiny thing but it makes a real difference. If today was worth a coffee to you, the link is buy me a coffee dot com slash fexingo. That's it. No pressure, no upsell. Luna: And we mean that — just a way to keep the economics conversation going without commercials. Now, back to corn: Lucas, you mentioned the June thirtieth USDA report. What specifically should listeners watch for? Lucas: Two things: acreage and quarterly stocks. The market is expecting planted corn acreage to be around ninety-two million acres, which would be up slightly from last year. But if the actual number comes in below expectations — say, under ninety-one-point-five million — that could ignite another rally. For stocks, the key is whether old-corn inventories are tighter than the trade expects. If stocks are drawn down more than anticipated, it reinforces the bullish narrative. Luna: And for wheat and soybeans, any key levels? Lucas: For wheat, watch the winter wheat production estimate. If yields come in higher than the USDA's initial forecast, that could push prices lower. For soybeans, the focus is on Chinese buying — if they start booking more U.S. cargoes, beans could play catch-up. But right now, the corn market is the story. Luna: Alright, so to wrap it up: corn is surging on weather worries, strong exports, and regulatory support, while the rest of the ag complex and commodities in general are struggling. The big test comes June thirtieth with the USDA reports. Lucas: That's the setup. And beyond the data, keep an eye on the weather maps. If the Midwest gets rain in the next ten days, corn might cool off. If not, this rally has room to run. Either way, it's a fascinating moment to watch how real-world factors — from a peace deal to a dry spell — converge in one commodity price.
