BHP's Jansen Potash Project: A High-Stakes Bet on a 2035 Deficit It Must Fund Itself To Reach

The potash market is caught between two realities. On one side, the near-term outlook is one of ample supply. Production from major exporters like Canada, Belarus, and Russia is at record levels, with global output hitting 76.6 million metric tons in 2024. This has kept the market well-supplied and prices relatively stable in the short run. Yet, beneath this surface of current abundance, a long-term structural shift is being forecast. The global market is projected to grow at a CAGR of 4.76%, expanding from an estimated $63.23 billion in 2025 to $100.66 billion by 2035.

This growth trajectory is driven by persistent demand from agriculture, which accounts for the vast majority of consumption. The International Fertilizer Association notes that global fertilizer use has recovered strongly, and demand for potash is expected to keep rising. BHP Group's head of potash, Karina Gistelinck, frames the outlook starkly: she expects the market to tighten over the next decade as demand grows 2% to 3% annually. That growth rate, she argues, will outpace the available supply of new capacity, leading to a market deficit expected by 2035.

The path to that deficit is complicated by geopolitical risks that are adding strain to supply chains. While current production is high, the war in the Middle East and other international tensions have already triggered a fertilizer supply shock, prompting farmers worldwide to secure nutrients. This volatility underscores a key vulnerability. The current supply surplus, while real, may not be sufficient to absorb both steady demand growth and the persistent shocks that can disrupt trade flows from traditional producers.

The bottom line is a clear divergence. The market is structurally shifting toward tighter conditions, but the timeline for that pressure to materialize is measured in years, not quarters. For now, the ample supply from established producers provides a buffer. Yet the long-term growth projection and the head of potash's warning point to a future where supply must catch up to demand, making projects like BHP's Jansen critical to the equation.

The Current Market Reality: Affordability vs. Structural Tightness

The market today is a study in contrasts. On one hand, the numbers point to a well-supplied and affordable potash market. On the other, the long-term growth narrative suggests a future deficit. The current price action captures this tension. The potash spot price stands at $372.50 per metric ton, a level that reflects a steady climb over the past year. Yet, that move has been modest in the near term, with the price ticking up only 1.78% from last month and remaining within a tight band of late-2025 highs. This pattern of a recent uptick within a stable range signals that while underlying demand is firm, there is no immediate scarcity. This pattern of a recent uptick within a stable range signals that while underlying demand is firm, there is no immediate scarcity.

That stability is underpinned by record production and ample capacity. Global potash output hit a record 76.6 million metric tons in 2024, driven by strong contributions from Canada, Belarus, and Russia. This production surge has kept the market well-supplied. More importantly, the supply pipeline is expanding. Global potash capability-the ability to mine and process-is projected to rise 11% to 59.8 million metric tons by 2029. Even as demand grows, this supply growth is expected to maintain a stable surplus, with the theoretically available surplus forecast to remain at 14% of supply capability in 2029.

Demand itself is a key driver of this affordability. Global fertilizer use, which includes potash, recovered strongly in 2024 to reach a new record of 206 million metric tons. This recovery, following the sharp contractions of 2021 and 2022, is now translating into steady demand growth. The International Fertilizer Association projects this annual growth to be in the 1% to 2% range through 2029. In other words, the market is seeing the kind of demand expansion that supports price stability and affordability, not scarcity.

So where does the long-term tightness thesis fit in? The structural shift is not a near-term reality but a future projection. The current surplus and record production provide a buffer. The tightness forecast for the next decade hinges on the market's ability to absorb both this steady demand growth and the persistent shocks that can disrupt supply chains, as seen with recent geopolitical tensions. For now, the balance is tilted toward supply. The market is well-supplied, and the affordability that comes with it is a direct result of that current equilibrium. The long-term narrative, however, is built on the expectation that this balance will eventually shift.

The Jansen Project: A Critical Supply Anchor with Escalating Costs

BHP's Jansen project is positioned as the primary solution to the market's projected deficit. Its scale is immense, with the first stage designed to produce 4.1 million tons annually and a potential second phase doubling that output to 8.5 million tons early next decade. The project is scheduled to begin operations in mid-2027, placing it squarely in the timeframe needed to address the anticipated supply gap. In theory, Jansen is the anchor that could stabilize the market as demand growth outpaces new capacity.

Yet the project's viability is now under a heavier financial burden. The investment for Stage 1 has escalated to $8.4 billion, a $1.2 billion increase from the previous estimate. This surge, driven by inflation, design changes, and lower-than-expected productivity, raises the hurdle for a successful return. The project's updated internal rate of return now sits in a range of 7.9% to 9.1%, while the expected payback period stretches to 11 to 15 years from first production. For a company betting on potash as "the iron ore of the future," these numbers underscore a significant execution risk.

The financial impact is clear. The cost overrun means the project's long-term economics are now more dependent than ever on sustained high potash prices over its 90-year life. Its underlying EBITDA margins remain strong at approximately 63% to 64% due to its low-cost position, but that advantage must now offset a higher initial capital outlay. This makes the project more sensitive to price volatility and demand shocks, which are already a feature of the market.

The bottom line is that Jansen remains a critical asset for BHP and the global potash supply chain. Its timeline aligns with the projected deficit. But the escalating costs have transformed it from a straightforward expansion into a more complex financial commitment. The project's success now hinges not just on technical execution, but on the market delivering the sustained price environment required to justify its elevated price tag.

Market Implications and Forward Catalysts

The investment case for potash is now a story of two timelines. The long-term structural thesis-built on demand growing 2% to 3% annually and a projected market deficit by 2035-supports a structural bull case for prices. This outlook is anchored by the expectation that steady demand growth will eventually outpace the available supply of new capacity. For investors, this suggests that the current period of affordability and ample supply is a temporary equilibrium, not a permanent state.

Yet the near term is dominated by a different reality. Record production, particularly from Canada, Belarus, and Russia, is keeping the market well-supplied. The theoretically available surplus is forecast to remain at 14% of supply capability through 2029. This oversupply dynamic is the primary reason prices have remained stable, despite the long-term growth narrative. Any further expansion of capacity, especially from major producers in Canada, could easily delay the onset of price strength, reinforcing the market's current affordability.

The primary catalyst for the bull case is clear: the successful ramp-up of BHP's Jansen project in mid-2027. This is the single largest planned addition to global capacity and is scheduled to begin operations just as the market is projected to tighten. Its ability to deliver on time and at its projected cost is the linchpin. Any further delays would directly challenge the timeline for easing the deficit and could prolong the period of price pressure from oversupply.

Key risks remain on both sides of the ledger. Execution risk is paramount, with the project's $8.4 billion investment and extended payback period making it vulnerable to continued cost overruns. Geopolitical disruptions to existing supply chains, while not currently affecting potash as severely as other nutrients, could still introduce volatility. More broadly, the entire thesis depends on demand growth meeting projections. A slowdown in global fertilizer use would undermine the tightness forecast and extend the period of surplus.

The bottom line is one of building pressure beneath a stable surface. The long-term deficit thesis is gaining traction, but it is being held at bay by current supply gluts and affordability. The market's forward view hinges on a single, massive project coming online on schedule. For now, the balance is tilted toward supply, but the fundamental shift toward scarcity is the pressure that is steadily building.
