Key takeaways

  • Today's rhodium price in each of 20 currencies is the US dollar quote per troy ounce converted at the current exchange rate, whose source and time the widget prints beside the price.
  • Rhodium is a platinum group metal, element 45 (Rh, CAS 7440-16-6), expensive because mines produced only 701,000 troy ounces (21.8 t) of it in 2025, according to Johnson Matthey's PGM Market Report of May 2026.
  • Rhodium has no exchange spot price: no futures contract, benchmark auction or clearing house exists for rhodium anywhere, so every published rhodium price is a refiner or dealer quote.
  • The rhodium price moves on three forces: South African mine supply, autocatalyst demand and recycling from scrapped vehicles.
  • The highest rhodium price on record is around $29,800 per troy ounce in March 2021, on dealer-quoted series; no exchange or benchmark confirms the figure.

What Is the Rhodium Price Today?#

The rhodium price today is $9,000.00 per troy ounce in US dollars (dealer quote, 5 Oct 2026, 15:30 UTC), 0.00% against the previous quote. The widget shows the dealer's bid of pending and ask of pending side by side and labels which one the headline uses, because the gap between the two is wider for rhodium than for any exchange-traded precious metal. A "stale" badge appears after 60 minutes without a new rhodium quote.

Rhodium is one of six platinum group metals (PGMs), and each of the six is priced from a different mix of sources. All six live quotes sit side by side under platinum group metal prices today.

Rhodium Price per Troy Ounce, Gram, Kilogram and Pound#

One troy ounce of rhodium costs $9,000.00, one gram $289.36, one kilogram $289,356.72 and one avoirdupois pound $131,250.00 at the current quote. One troy ounce equals exactly 31.1034768 grams, one kilogram holds 32.1507466 troy ounces, and one avoirdupois pound (453.59237 g) holds 14.5833333 troy ounces. The rhodium price for seven common weights is listed below in US dollars and Indian rupees.

A change of zero usually means the dealer did not move its quote. The rhodium price chart plots the same series live and over longer ranges.

What Is Rhodium and Why Is It So Expensive?#

Rhodium is a platinum group metal, element 45 (Rh, CAS 7440-16-6), expensive because mines produced only 701,000 troy ounces (21.8 t) of it in 2025, according to Johnson Matthey's PGM Market Report of May 2026. Recycling added 312,000 oz, for combined supply of 1,013,000 oz (31.5 t) against 2025 demand of 1,063,000 oz. Is rhodium worth any money? Every gram carries a quoted value: the 2024 annual average was $4,660.44 per troy ounce on the Engelhard unfabricated series (USGS Mineral Commodity Summaries, February 2026). The three reasons rhodium costs so much are listed below.

  • By-product supply: rhodium comes out of the same ore, smelter and refinery as platinum and palladium, so no mine opens or expands on a rhodium price.
  • Concentrated supply: South Africa mined 81% of primary rhodium in 2025 (IPA/SFA Rhodium Factsheet 2026).
  • No substitute: rhodium reduces nitrogen oxides (NOx) in gasoline three-way catalysts, and the IPA/SFA factsheet names no metal that replaces it in that role.

PubChem lists rhodium's atomic mass as 102.9055, its density as 12.4 g/cm3 and its melting point as 2,237 K (1,964 °C). The metal does not tarnish or oxidize in air. Isotopes, compounds and properties of rhodium (Rh), element 45 are on the element page.

Is There a Rhodium Spot Price? Who Quotes Rhodium#

Rhodium has no exchange spot price: no futures contract, benchmark auction or clearing house exists for rhodium anywhere, so every published rhodium price is a refiner or dealer quote. Only platinum and palladium have NYMEX futures and a regulated benchmark, the London auctions that ICE Benchmark Administration (IBA) has run since 1 July 2026. How those auctions set LBMA platinum and palladium prices is covered separately.

The six places a rhodium price could come from, and what each one publishes, are compared below.

Source Unit Form Frequency Who can trade at it
Johnson Matthey base price USD per troy ounce Sponge, minimum 99.9% Each business day JM customers with a manufacturing need, KYC and credit approval; not individuals
Umicore EUR per gram "Sales Price Fabricated" Daily Indicative only, in Umicore's own words
Heraeus USD per troy ounce in its weekly report Price series for Rh, Ir and Ru Business hours, plus a weekly report Not stated in the published series
Kitco USD per troy ounce, bid and ask Not specified Continuous Indicative quote, not a dealing price
LPPM No price Rhodium sponge accreditation list Not applicable Sponge "will not become good delivery material"
LBMA/IBA auction, NYMEX futures None for rhodium Platinum and palladium only Not applicable Not applicable

Refiner-traders make the market: Johnson Matthey, Heraeus, Umicore and BASF, plus producers' marketing arms such as Valterra Platinum, Impala, Sibanye-Stillwater and Nornickel, trading bilaterally with no order book. Each of the rhodium price data sources, with its license and update time, is documented under rhodium price data sources.

Johnson Matthey Base Prices: The Most-Cited Rhodium Price#

Johnson Matthey base prices are the prices at which Johnson Matthey quotes rhodium sponge to its wholesale customers, in US dollars per troy ounce, and they are the figure most charts mean by "the rhodium price". JM calls them "quoted prices for our customers of wholesale quantities of platinum group metals," set by its trading desks in the USA, Hong Kong and the UK. The four features that define a JM base price are listed below.

  • Form: sponge, the powder that catalyst and chemical makers use, at a minimum purity of 99.9% for rhodium.
  • Basis: JM's own view of prevailing market prices, not an auction result.
  • Status: a company quote, not a regulated benchmark.
  • Access: only customers with a genuine manufacturing need that pass KYC and credit checks; not individuals.

JM quotes five metals and not osmium. Rhodium, iridium and ruthenium are minor PGMs whose prices exist only as refiner quotes; the differences between Johnson Matthey, Heraeus and Umicore are set out in how minor PGM prices are quoted.

Umicore, Heraeus and Kitco Rhodium Quotes#

Umicore quotes rhodium in euros per gram as a "Sales Price Fabricated", €254.95 per gram on 5 August 2026, and states that its prices "are of pure statistical nature and must be looked at as indications only". A fabricated price includes the cost of making metal into a finished product, so this page never converts it to dollars per ounce. Umicore's price tool distinguishes six price types: opening, purchase, sales unfabricated, sales fabricated, fixing and post-fixing. The two other regular rhodium quotes are listed below.

  • Heraeus: publishes rhodium, iridium and ruthenium price series beside platinum and palladium, with no osmium, and a weekly market report; its weekly rhodium quote read $7,550 per troy ounce on 11 August 2025 (Heraeus, Precious Appraisal).
  • Kitco: publishes a continuous rhodium bid and ask, and rhodium is the only minor PGM it quotes both ways; the figures are indicative, not wholesale dealing prices.

Why the Rhodium Bid-Ask Spread Is So Wide#

Rhodium dealers quote a much wider gap between buying and selling prices than for gold, silver, platinum or palladium, because rhodium trades bilaterally, infrequently and without an exchange. Across the precious metals, spreads widen in a fixed order: gold, silver, platinum, palladium, rhodium, then iridium and ruthenium, with osmium widest.

What does the gap cost a holder? A seller receives the dealer's bid and a buyer pays the ask, so a purchase and resale costs the full distance between pending and pending at today's quote. The spread widens again for very small or very large lots, for sponge rather than bars and outside London and Zurich.

Quote series also look smoother than the market, because dealers republish quotes on a schedule whether or not metal changed hands.

What Moves the Rhodium Price?#

The rhodium price moves on three forces: South African mine supply, autocatalyst demand and recycling from scrapped vehicles. Johnson Matthey's 2025 figures show all three: primary supply of 701,000 oz, automotive demand of 899,000 oz and autocatalyst recycling of 312,000 oz. Supply cannot answer a higher price, because rhodium is a by-product of platinum and palladium mining, and demand cannot switch away, because no metal takes over rhodium's NOx function.

Supply: South Africa Mines 81% of Primary Rhodium#

South Africa mined 81% of the world's primary rhodium in 2025, followed by Russia (9%), Zimbabwe (6%) and North America (3%), according to the IPA/SFA Rhodium Factsheet 2026. The table below sets those shares beside Johnson Matthey's ounce figures for the same year; the two sources use different data vintages, so their numbers are never combined in one calculation.

Country or region Share of primary supply, 2025 (IPA/SFA) Primary supply, 2025, koz (Johnson Matthey)
South Africa 81% 566
Russia 9% 68
Zimbabwe 6% 45
North America 3% 15
Others 1% 7
Total 100% 701

Shares: IPA/SFA Rhodium Factsheet 2026 (Johnson Matthey January 2026 data). Ounces: Johnson Matthey PGM Market Report, May 2026.

What country is rich in rhodium? South Africa, whose UG2 ore holds a much higher share of rhodium, iridium and ruthenium than the Merensky Reef, a share that may exceed 20% of PGM content (IPA/SFA Ruthenium Factsheet 2026). North America, the United States and Canada, supplied 15,000 oz in 2025 (Johnson Matthey). Ores and deposits by country are covered on where rhodium is found.

Demand: Autocatalysts, Chemicals and Glass#

Autocatalysts took 84.6% of rhodium demand in 2025, 899,000 of 1,063,000 ounces on Johnson Matthey's figures, just below JM's quoted 85-95% band. In a three-way catalyst, rhodium reduces NOx to nitrogen while platinum and palladium oxidize carbon monoxide and hydrocarbons.

IPA/SFA names the long-term risk as the switch to battery electric vehicles, not substitution by another metal. How the three metals divide the converter's work is explained on PGMs in autocatalysts.

The other four 2025 demand segments, in thousand ounces on Johnson Matthey's figures, are listed below.

  • Chemical: 91 koz, for hydroformylation and Monsanto-process acetic acid catalysts.
  • Glass: 38 koz, after net selling in 2021 to 2024 as Chinese fiberglass makers thrifted rhodium out of alloys.
  • Other: 26 koz.
  • Electrical and electronics: 9 koz.

What is rhodium used for beyond cars? Glassmaking bushings of 5% to 20% rhodium in platinum, nitric acid gauzes and Type R, S and B thermocouples, all covered on rhodium uses.

Rhodium Market Balance 2025 to 2026: Johnson Matthey#

Johnson Matthey forecasts a small rhodium surplus of 15,000 ounces in 2026, its first since 2022, after a 50,000-ounce deficit in 2025 (PGM Market Report, 14 May 2026). JM expects automotive demand to fall 4.8% to 856,000 oz on lower combustion-engine output, while recycling rises 8.7% to 339,000 oz. JM's balance for 2023 to 2026 is listed below, all on JM's own basis.

Johnson Matthey, koz 2023 2024 2025 2026 forecast
Primary supply 695 729 701 681
Secondary supply (autocatalyst) 289 292 312 339
Total demand 1,061 1,030 1,063 1,005
Autocatalyst demand 979 915 899 856
Market balance -77 -9 -50 +15

Supply, demand and volatility across the full cycle are analyzed on rhodium market.

JM groups rhodium with palladium as the metals most exposed to falling combustion-engine output. Mine supply still falls in its forecast, from 701,000 oz to 681,000 oz.

A surplus forecast is not a price call. Each rhodium price forecast, with its forecaster and publication date, is set side by side on rhodium price forecast.

What Is the Highest Rhodium Price Ever?#

The highest rhodium price on record is around $29,800 per troy ounce in March 2021, on dealer-quoted series; no exchange or benchmark confirms the figure. The level appears on aggregator sites that likely share one upstream source, and Johnson Matthey's monthly-average series peaks well below it. The record points, each with its series or source, are listed below.

Record Price (USD per oz t) Date Series and source
Earlier cycle high Above 10,000 2008 IPA/SFA Rhodium Factsheet 2026
Decade low About 600 2016 findbullionprices.com; mintedmetal
All-time high Around 29,800 March 2021 Dealer-quoted series, not independently confirmed
2026 peak 12,000, a three-year high Late February 2026 Johnson Matthey, PGM Market Report, May 2026

Dealer and producer series, not one exchange price.

Two forces met in 2020 and 2021. Tighter NOx limits under China 6 and Euro 6d raised rhodium loadings per vehicle, while South African outages, including the 2020 outage at the Waterval converter plant of Anglo American Platinum (now Valterra Platinum), cut supply. With no futures market to hedge, buyers had to hold physical metal.

Every dated level since 2008 is collected on rhodium price history.

Rhodium Price Cycles 2008 to 2026#

Rhodium peaked at $12,000 per ounce in late February 2026, a three-year high, up from $5,000 in early 2025 (Johnson Matthey, May 2026). The cycles since 2008 are listed below, each with its source.

  • 2008 to 2009: above $10,000 in 2008 (IPA/SFA), then $950 (Reuters) as automakers cut rhodium use.
  • 2016: about $600, the decade low (findbullionprices.com; mintedmetal).
  • 2021: around $29,800 in March, on dealer-quoted series.
  • Mid-2023: below $5,000 (mintedmetal).
  • Late 2024: $4,400 to $4,750 (Phoenix Refining).
  • 2025: through $5,000 early in the year, above $7,000 in late July, $8,000 in October and above $9,000 in the final days of December (Johnson Matthey).
  • 2026: $12,000 in late February, then back toward $10,000 in March (Johnson Matthey).

Annual averages smooth these spikes. The Engelhard unfabricated series, published by USGS in its Mineral Commodity Summaries of February 2026, is listed below for 2021 to 2024.

Year Annual average (USD per oz t)
2021 20,254.10
2022 15,585.00
2023 6,660.58
2024 4,660.44

On that series the 2024 average was 23% of the 2021 average. The rhodium price chart draws the path between these points.

Rhodium Price vs Gold and Platinum Today#

Rhodium trades at 217.6%% of the gold price and 526.0%% of the platinum price today, $9,000.00 against $4,135.60 and $1,711.00 per troy ounce. Above 100%, rhodium is the costlier metal. The widget prints the gold price and the platinum price today beside the rhodium quote.

Is rhodium costlier than gold? The live ratio answers it at any moment, and the multiple swings widely. On the Engelhard unfabricated series (USGS, February 2026), rhodium averaged 18.5 times the platinum price in 2021 and 4.9 times in 2024.

Price is one difference; density, rarity and use are others, compared on rhodium vs gold and rhodium vs platinum.

Sell, Buy and Track Rhodium at Today's Price#

Rhodium sellers, buyers and industrial users use today's quote as the reference for scrap payouts, bar premiums and price alerts. The same quote anchors the wider platinum group metals market, from mine supply to recycling.

Quotes for the other five metals follow the same logic under platinum group metal prices today.

Selling Rhodium: Catalytic Converter and Industrial Scrap#

Scrapped catalytic converters supply all open-loop recycled rhodium: 312,000 ounces in 2025, about 31% of total rhodium supply on Johnson Matthey's figures. Refining recovers around 95% of a spent autocatalyst's PGM content, including rhodium (IPA/SFA Rhodium Factsheet 2026). Value starts from the metal loading: see how much rhodium is in a catalytic converter.

Closed-loop recycling of industrial metal is larger: 28 of 37 t recycled in 2024 (Johnson Matthey Circularity Whitepaper 2024). Payouts are covered on rhodium scrap value.

Buying Rhodium: Bars, Sponge and Exchange-Traded Products#

Rhodium buyers pay the dealer's ask, not an exchange price, for small bars, sponge or exchange-traded products, such as the Xtrackers Physical Rhodium ETC (ISIN GB00B684MW17, issued by DWS). Rhodium ETFs held about 22,000 oz at the end of 2025, the most in more than five years (Johnson Matthey, May 2026).

Sponge is the standard traded form, but LPPM states that vaults cannot accept rhodium sponge for spot value. Bars, powder and their risks are compared on rhodium investment.

Rhodium Price Alerts and the Daily Report#

DailyPlatinum price alerts email you when rhodium crosses a price you set, in any of 20 currencies and per ounce, gram or kilogram. Setup for every metal is on platinum price alerts, and the daily PGM price and market report records the rhodium quote and its cause each business day.

Rhodium Plating and Jewelry#

Rhodium plating is a thin electroplated layer of rhodium on white gold, platinum or sterling silver, used because rhodium does not tarnish or oxidize. The layer wears with use, so rhodium-plated white gold needs periodic replating while solid platinum does not. Process and thickness are on rhodium plating, marking rules on rhodium-plated metals and skin-contact questions on rhodium toxicity.

Other Platinum Group Metal Prices Today#

The other five platinum group metals, platinum, palladium, iridium, ruthenium and osmium, each have a live price page. Only platinum and palladium trade as futures, and Johnson Matthey quotes every PGM except osmium.

Metal Symbol Main price series Live price page

Rhodium Price FAQ#

How much is 1 oz of rhodium worth today?#

One troy ounce of rhodium (31.1034768 g) is worth $9,000.00 on the dealer quote at 5 Oct 2026, 15:30 UTC. That is a quote for pure metal: a dealer buying your ounce pays the bid, pending, and a dealer selling one charges the ask, pending. The same ounce is worth €8,026.83 in euros.

What is the cost of 1 gram of rhodium?#

One gram of rhodium costs $289.36 at today's quote, the troy-ounce price divided by 31.1034768, and ten grams cost $2,893.57. Umicore's €254.95 per gram of 5 August 2026 is a different price type, for fabricated metal. Gram prices in other currencies are on rhodium price per gram today.

How much is 1 lb of rhodium worth?#

One pound of rhodium (453.59237 g, or 14.5833 troy ounces) is worth $131,250.00 at today's quote. The pound here is the avoirdupois pound of everyday use, while precious metals are weighed in troy ounces, so the pound value is the ounce price multiplied by 14.5833333. One kilogram, at $289,356.72, equals 2.2046 pounds.

Is the rhodium price going to go back up?#

No price direction is certain; Johnson Matthey's PGM Market Report of 14 May 2026 forecasts a small 15,000-ounce rhodium surplus in 2026 as automotive demand falls 4.8%. Rhodium had already risen from $5,000 in early 2025 to $12,000 in late February 2026 before retreating toward $10,000 in March (Johnson Matthey). Named outlooks sit on rhodium price forecast.

Is rhodium a good investment?#

Rhodium differs from gold as a holding in liquidity: it has no exchange, wide dealer spreads and few exchange-traded products; on dealer series it fell from around $29,800 (March 2021) to below $5,000 (mid-2023, mintedmetal). DailyPlatinum gives no investment advice; bars, powder and their risks are set out on rhodium investment.

Why is the rhodium price different on each website?#

Rhodium prices differ between websites because each site shows a different dealer's quote, in a different form, currency and time: Johnson Matthey quotes sponge in USD per troy ounce, Umicore fabricated metal in euros per gram. Kitco shows a bid and ask, and chart sites show whichever series they license. Each series is documented under rhodium price data sources.

What are rhodium's symbol, atomic number and CAS number?#

Rhodium has the symbol Rh, atomic number 45 and CAS number 7440-16-6, with an atomic mass of 102.9055 (PubChem). Natural rhodium consists of a single isotope, rhodium-103. The element, its properties and its compounds are covered on rhodium (Rh), element 45.
