¥670 billion. Roughly $4.3 billion. That is what the Iran war will cost Toyota Motor in lost operating profit this fiscal year — the largest quantified corporate exposure to the Middle East crisis disclosed by any major company to date.

The figure, released Friday as part of Toyota’s annual earnings, dropped the world’s largest automaker’s operating profit forecast to ¥3 trillion ($19.1 billion) for the year ending March 2027. That is a staggering 35% below the ¥4.59 trillion median estimate from 23 analysts polled by LSEG. Toyota shares fell as much as 2.2% in Tokyo, closing at their lowest level since mid-October. The stock is down 11% year-to-date.

The Two-Front War on Toyota’s Margins

The Middle East drag — ¥670 billion — combines higher energy and materials costs, disrupted shipping lanes, and a sharp drop in regional sales. Toyota said Middle East sales fell sharply in March after shipments were disrupted, according to Channel News Asia. US tariffs add a second, even larger burden: ¥1.38 trillion, unchanged from the previous fiscal year.

Between the two, Toyota is absorbing blows from opposite sides of the globe. Fourth-quarter operating profit fell 49% to ¥569.4 billion, down from ¥1.1 trillion a year earlier. Revenue, paradoxically, rose 1.9% to ¥12.6 trillion — nearly matching analyst expectations. The company is still selling plenty of cars. It just cannot stop rising costs from devouring the proceeds.

The Bellwether Problem

If Toyota — with its unmatched scale, diversified manufacturing across North America and Southeast Asia, and genuine pricing power — is absorbing a ¥670 billion hit from the Middle East, the cascading effects across global supply chains are only beginning to surface.

Volkswagen CEO Oliver Blume said this week that tariffs alone represent a €5 billion ($5.9 billion) annual drag on the German group’s operating profit. Airlines have issued warnings as well, though none have matched Toyota’s Middle East figure. The automaker’s disclosure matters precisely because of its diversification: Toyota is not a niche player vulnerable to a single choke point. It is the world’s largest carmaker, and the war is still costing it more than $4 billion.

The Hybrid Paradox

The conflict has produced a cruel irony. Soaring oil prices are pushing consumers toward fuel-efficient vehicles — Toyota’s specialty. The company expects hybrid sales to exceed 5 million units this fiscal year for the first time ever. Demand for its core products is being boosted by the very crisis eating into its margins.

But a hybrid boom cannot outrun the cost structure of a war economy. Toyota posted weaker US quarterly sales in the first quarter amid concerns about affordability and fuel price pressures, according to CNBC. North American operations recorded an operating loss for the full fiscal year — a striking result for a region that has long served as a profit engine for Japanese automakers.

A New CEO’s Welcome Gift

This is the first outlook issued under CEO Kenta Kon, who assumed the top job last month. His predecessor, Yoichi Miyazaki, now serving as CFO, did not sugarcoat the trajectory.

“As CFO, I take very seriously the fact that this fiscal year will mark a third consecutive year of flat earnings outlook,” Miyazaki said, according to AFP. “On the other hand, we have not yet been able to fully counteract the impact of major shifts in the business environment, such as US tariffs and developments in the Middle East.”

Kon inherits a company that sold a record 11.3 million vehicles in the fiscal year ended March 2026, up 4.6%. This year, Toyota expects group sales to slip to 11.18 million, with Middle East disruption offsetting projected gains in North America and Asia. The company is also spending record amounts on R&D, partly driven by certification-related issues and capacity constraints.

What the Math Means for Everyone Else

Toyota adopted a six-month average for its foreign exchange assumptions this year rather than the usual monthly average, citing volatility. Its base rate is set at ¥150 to the dollar. The yen’s depreciation — roughly 17% against the dollar over four years — has been a rare tailwind for Japanese exporters, but a weak currency cannot compensate for tariff walls and war disruptions.

Japan’s trade deal with Washington lowered threatened auto tariffs from 25% to 15%. That is painful, but less catastrophic than the alternative. Toyota is pressing ahead with $1 billion in investments across two US plants as part of a broader $10 billion, five-year plan.

The figure that should worry boards far beyond the auto industry is ¥670 billion. This is not a worst-case projection or a sell-side analyst’s back-of-the-envelope estimate. It is baked into official company guidance. If Toyota is counting its losses this precisely, the rest of corporate Europe, Asia, and the Americas are almost certainly doing the same math behind closed doors — and many of them will not have Toyota’s margins to absorb the blow.
