For years, Morocco’s OCP has been held up as a textbook example of how to turn a raw material endowment into global industrial power. Sitting on the world’s largest phosphate reserves, it has built an integrated fertilizer empire that underpins food production from North America to sub‑Saharan Africa. The recent Middle East crisis, however, has shown that even a champion anchored in rock can wobble when a key imported input is suddenly removed.
At the heart of the story is sulfur. Phosphate rock is OCP’s great advantage, but modern fertilizers require more than ore. To turn rock into finished products, the group consumes millions of tons of sulfur and significant volumes of ammonia each year, both largely imported. When war flared in the Gulf region earlier this year and traffic through the Strait of Hormuz was effectively disrupted, global sulfur flows were hit hard. Prices more than doubled in a matter of months, and several major suppliers either halted exports or declared force majeure. For a buyer of OCP’s size, that was not a minor inconvenience; it was a direct shock to the cost base of the entire operation.
The impact showed up quickly in the numbers. In the first quarter of 2026, OCP’s revenue, gross margin and EBITDA all declined versus the previous year. At the same time, the group acknowledged that its sulfur bill had already jumped sharply between 2024 and 2025 as volumes and unit prices rose. To manage the latest spike and the logistical uncertainty, OCP chose an unusual response for a company accustomed to expansion: it advanced maintenance work and deliberately cut fertilizer output by about 30 percent for a period, using the slowdown to retool plants and conserve inputs. That decision even contributed to a temporary technical incident on its flagship pipeline linking mines to its coastal complex, underlining how rare and disruptive such a pause has been.
Behind the headline figures, the episode hit a company that was already carrying significant weight. The wage bill had grown rapidly in recent years as OCP expanded staff and invested in affiliated entities, from engineering arms to its university. Debt had also climbed substantially since the early 2020s, reflecting an ambitious capex and bond‑issuance program designed to fund new plants, logistics and “green” projects. Although the group retained an investment‑grade credit rating and stressed the resilience of its business model, the combination of higher leverage and a sudden input shock naturally raised questions among analysts and insiders about how much stress the system could absorb.
What makes this crisis particularly revealing is that it is different in structure from the 2022 fertilizer boom. The war in Ukraine mainly disrupted potash and some nitrogen supply, driving broad price increases that benefited OCP, which reported record results. This time, the pressure has been concentrated on sulfur and, to a lesser extent, ammonia—precisely the inputs where Morocco does not have domestic gas‑based production and must rely on imports from volatile regions. Russian and Gulf producers, by contrast, sit on cheap gas and can make sulfur and ammonia at scale. The episode therefore highlighted OCP’s Achilles’ heel: it is globally dominant and vertically integrated in phosphates, but it is structurally exposed on some of the other pieces of the fertilizer puzzle.
To its credit, the company has not been blind to that vulnerability. Over the past several years, OCP has steadily diversified its sourcing, tapping suppliers in the Middle East, Europe, North America and the former Soviet space, and signing long‑term offtake agreements. When a major sulfur deal with a Gulf producer was knocked out by force majeure, the group moved to draw on Iraq, Canada and direct imports of sulfuric acid. It also dusted off plans to exploit pyrite deposits at home as a partial substitute and leaned on strategic stockpiles to bridge the gap while shipping lanes were choked. In corporate language, executives have presented this period as a real‑world stress test of their supply chain and crisis‑management systems—one they argue the company passed.
At the same time, OCP has tried to address the problem from the demand side. One pillar of its strategy has been to shift its product mix toward Triple Super Phosphate (TSP), a formulation that uses significantly less sulfur than some standard fertilizers. TSP sales have risen strongly, to the point where they now represent the majority of exports, and managers point to this as a way of reducing exposure to sulfur volatility while serving markets that need high‑phosphate inputs. Another pillar has been a broad “green” investment plan launched in late 2022, which aims to use renewable power in Morocco to produce low‑carbon, “green” ammonia and ultimately cut import dependence. OCP still targets roughly one million tons of domestic green ammonia output in the next few years, but timelines have slipped relative to initial announcements, leaving a gap in which the company remains reliant on foreign supply.
OCP’s story carries several implications. First, it shows that even large, state‑linked resource firms can be destabilized by chokepoints far from their own borders. The Strait of Hormuz closure was not “about” Morocco, yet it directly hit one of the world’s key fertilizer engines. Second, it underlines how emerging‑market champions are trying to push up the value chain and de‑risk their inputs at the same time, investing in alternative chemistries and green capacity not just for climate reasons, but to avoid being held hostage by external shocks.
The episode raises a wider question relevant well beyond OCP: how much leverage and ambitious transformation can a company carry in a world where geopolitical disruptions to shipping and energy are becoming more frequent, not less? Morocco’s fertilizer giant has come through this particular storm with its balance sheet intact and its strategy formally unchanged. But the wobble has exposed the limits of a model built on one overwhelming advantage, phosphate rock, and reminded both the company and its partners that resilience in global food supply chains depends as much on the “boring” inputs like sulfur and ammonia as on the resources that grab the headlines.
