On July 15–16, 2026, BHP Group flagged that it needs copper prices close to US$6.50 per pound to offset an expected 12% fall in output for FY2027 — mostly because ore grades at its flagship Escondida mine in Chile are dropping, cutting production by 16.7%. Copper already accounts for 51% of BHP's underlying EBITDA, making this a very high-stakes single-commodity dependency.
Here's what caught my eye this week: a mining giant basically publishing its own stress test in public. BHP says it needs copper at ~US$6.50/lb next year just to hold its earnings flat, even as its biggest mine produces less.
Here is how a CFO reads this — it's a pure EBITDA sensitivity story.
EBITDA (Earnings Before Interest, Tax, Depreciation and Amortisation) is the operating profit before financing and accounting charges — think of it as 'cash the business generates from running itself.' BHP's copper division delivered a record US$8 billion EBITDA in the last half-year, and copper now makes up 51% of the whole group's EBITDA. That means one commodity, from a handful of mines, is carrying the majority of earnings.
A CFO would immediately ask: what is our EBITDA sensitivity to a $1 move in copper price? If volume drops 12% and price slips even slightly, two levers move against you at the same time. That's operating leverage in reverse.
The US$6.53/lb average BHP saw in Q4 FY2026 is barely above the US$6.50 floor it needs. That's a razor-thin cushion. A CFO would be stress-testing scenarios where copper trades at $5.50 — and figuring out which capex commitments still make sense.
For any operator or founder: whenever one product, customer, or market drives the majority of your EBITDA, you don't just have a great business — you have concentrated risk. The margin of safety matters as much as the margin itself.
