Rhodium Smashes Past $20,000 an Ounce as Automakers Scramble for Supply

Rhodium just quietly climbed roughly 19% in October alone to break above $20,000 an ounce for the first time on record. Almost nobody outside the metals trade noticed.

While traders spent October watching gold hover near record territory and platinum grind out steady gains, rhodium did something far more dramatic. The metal surged past $20,000 an ounce this month, according to a report from Mining.com, in what the outlet called precious metals’ biggest rally. That’s a roughly 19% jump in a single month, outpacing every other member of the platinum group and leaving gold’s 2026 gains looking almost tame by comparison.

Rhodium isn’t like gold or silver. Nobody mines it on purpose. It comes out of the ground almost entirely as a byproduct of platinum, palladium and nickel mining, and South Africa alone supplies somewhere around 80% of the world’s output. That concentration is the whole story here. When something goes wrong at a handful of South African producers, there is no second source to lean on, and the market has spent much of 2026 learning that the hard way.

The demand side of this is unusually inflexible. Rhodium is a core ingredient in catalytic converters, the devices that scrub nitrogen oxide emissions out of a car’s exhaust before it ever reaches the air. As governments tighten emissions standards worldwide, automakers aren’t just hoping to use rhodium, they’re legally required to. You can’t swap it out for a cheaper substitute and still pass an emissions test. That gives suppliers almost no bargaining power and gives producers all of it.

Consultancy Metals Focus has been tracking this squeeze for months. The firm projects rhodium inventories will fall below three months of demand coverage in 2026, a level that leaves almost no buffer if a mine floods, a smelter goes down, or a labour dispute drags on in South Africa’s platinum belt. Power supply disruptions and labour unrest in those mining regions have historically knocked 5% to 10% off annual output in bad years, and each time that’s happened, rhodium has spiked. This is, by some accounts, the fourth major price surge of its kind in the metal’s history.

Here’s the part that should give pause to anyone chasing the rally now: rhodium has been here before, and it didn’t end well for latecomers. The metal hit an all-time high of $29,800 an ounce back in March 2021, then collapsed hard enough that it spent most of 2023 and 2024 trading closer to $4,000 to $5,000. Thin, illiquid markets cut both ways. The same lack of a deep secondary supply that sends prices rocketing on the way up offers no cushion on the way down once automakers find workarounds or demand softens.

And demand might already be cooling. Some industry forecasts point to total 2026 rhodium demand falling by roughly 6%, driven by softer growth in internal combustion vehicle production as electric vehicles, which don’t need catalytic converters at all, keep taking market share. That’s the tension sitting underneath this rally: a metal getting squeezed by a shrinking long-term customer base, rallying hard anyway because the near-term supply math is that broken.

Metals Focus is still bullish through year-end, forecasting rhodium prices will rise roughly 62% for 2026 overall, trailing only platinum’s projected 71% gain among the platinum group metals and running well ahead of palladium’s expected 37% rise. Platinum, palladium, rhodium and ruthenium are all up sharply over the past year, 110%, 51%, 83% and 158% respectively by some industry tallies, which tells you this isn’t a rhodium story alone. It’s a platinum group metals story, and rhodium just happens to be the loudest voice in the room right now.

Frankly, the traders piling into rhodium today are betting the supply crunch outlasts the demand slowdown. That’s a real bet, not a sure thing. A metal with no deep futures market, a handful of producers, and a 2021 crash still fresh in institutional memory is not a place for anyone who can’t stomach a round trip back to $8,000.

For now, though, the automakers have no choice but to pay up. The emissions rules aren’t going anywhere, and neither is South Africa’s grip on the mine output that decides whether this rally has another leg or ends the way the last one did.
