The global rhodium market is heading toward its first surplus in four years, according to TD Commodity Strategy, as supply recovers and automotive demand weakens.
TD forecasts a 20,000-ounce surplus in 2027, reversing a projected shortfall of approximately 50,000 ounces in 2026. The shift is expected to push prices down from around $9,000 per troy ounce to $7,600 in 2027 and $6,500 in 2028.
The outlook reflects a structural change for a metal whose scarcity and importance in vehicle emissions control have produced extraordinary price swings. Rising mine production and an anticipated recovery in autocatalyst recycling are expected to coincide with slowing demand as battery-electric vehicles gain market share and manufacturers reduce rhodium use.
Yet a return to surplus would not necessarily bring stability. After years of inventory drawdowns, the market retains little protection against supply interruptions. TD's projected surplus is a narrow cushion, not an end to the conditions that have made rhodium exceptionally volatile.
Approximately 80% of rhodium consumption comes from automotive catalytic converters, where the metal helps convert harmful nitrogen oxides into nitrogen. That concentration ties demand closely to internal combustion engine production.
Battery-electric vehicles require no exhaust catalysts, making their growing adoption a persistent headwind. Slower adoption could soften the near-term impact, while hybrids offer some support because they still require emissions-control systems. Frequent engine cold starts can also increase catalyst requirements in certain hybrid applications.
Nevertheless, electrification is progressively reducing rhodium's addressable automotive market.
Industrial users have already demonstrated how high prices can encourage lasting reductions in consumption. After rhodium surged to nearly $30,000 an ounce in 2021, glass and fiberglass manufacturers accelerated efforts to reduce the metal content of platinum-rhodium equipment.
Some applications moved from alloys containing around 20% rhodium toward formulations containing as little as 5%. Replacing older equipment also released metal back into the market, combining lower ongoing demand with additional secondary supply.
Automotive substitution presents a more complicated challenge. Rhodium is particularly effective at reducing nitrogen oxides, and palladium cannot simply replace it ounce for ounce without changes to catalyst design and performance.
The supplied analysis suggests certain substitution approaches could require five to eight ounces of palladium for each ounce of rhodium displaced. At those ratios, replacing 20,000 ounces of rhodium would require 100,000–160,000 ounces of palladium. Such changes would also require lengthy development and certification.
Those figures illustrate a potential cross-metal effect, not an inevitable demand shock. Substitution depends on relative prices and technical feasibility; falling rhodium prices would, all else equal, weaken the incentive to replace it.
The principal risk to TD's forecast lies on the supply side. South Africa accounts for approximately 85% of primary rhodium production, with five mines supplying roughly half of global output. Power shortages, flooding, equipment failures, or labor disruptions at a small number of operations can therefore alter the global balance.
Above-ground inventories are projected to provide only slightly more than three months of industrial consumption cover. Meanwhile, processing rhodium from mined material into refined metal can take more than three months, considerably longer than typical platinum and palladium processing cycles. Not all inventory is immediately available to consumers, and lost production cannot be replaced quickly. A relatively modest disruption could therefore erase the expected surplus and trigger another price spike. South Africa's geology adds to the challenge. Producers have increasingly shifted toward the rhodium-rich UG2 reef within the Bushveld Complex as other resources mature. UG2 can contain substantially more rhodium than the Merensky Reef, but its high chromite content complicates processing and can constrain smelter throughput.
Supply also responds slowly to rhodium prices because the metal is produced alongside platinum, palladium, and other commodities. Operators make investment and production decisions based on the economics of the entire basket, not rhodium alone. That can sustain output during a rhodium downturn, but it also means broader mine closures can remove rhodium supply regardless of the metal's own fundamentals.
Amandelbult, Valterra Platinum's conventional underground complex in South Africa, illustrates the interaction between operational risk and financial vulnerability. Flooding disrupted production in 2025, highlighting how problems at one major asset can delay the market's return to balance. Labor-intensive, deep-level operations also carry substantial fixed costs, making them more exposed to weaker commodity revenues than lower-cost, mechanized mines. If rhodium falls toward $6,500 an ounce, margins could narrow materially where it contributes a significant share of basket revenue. The ultimate effect would depend on platinum and palladium prices, exchange rates, costs, and each operation's production mix, not rhodium alone.
Production cuts would not necessarily follow immediately. South African labor law requires consultation over large-scale retrenchments, while mine shutdowns carry environmental, financial, and operational obligations. Producers may continue running marginal shafts while pursuing alternatives. Over time, however, sustained pressure could encourage closures or reduced investment. Those responses could remove the forecast surplus and tighten supplies of co-produced metals, including iridium used in proton-exchange-membrane hydrogen electrolysers. That could constrain hydrogen development, although its severity would depend on technology choices, recycling, catalyst thrifting, and future mine investment.
Secondary supply is another critical assumption behind the expected surplus. High vehicle replacement costs have encouraged motorists to retain cars longer, delaying the arrival of spent catalytic converters at scrapyards. Collection, processing, and refining constraints further limit how quickly recovered metal can reach consumers. Rhodium is also difficult to separate efficiently from other platinum group metals. Increased vehicle scrappage would support supply, but it would not translate immediately or fully into refined output.
The market's limited liquidity amplifies these physical constraints. Rhodium trades primarily over the counter rather than through a deep futures market, leaving prices sensitive to relatively small changes in available metal. Physically backed investment products can add pressure when inflows remove material from commercial circulation. TD's central forecast points to easing scarcity and lower prices. The distinction is that a modest annual surplus does not rebuild depleted inventories overnight. Rhodium may be approaching the end of its four-year squeeze, but a smoother market is far from assured.
