Commodity-Backed Stablecoins: Tokenized Gold, Silver, and Oil

Commodity-backed stablecoins give investors on-chain access to gold and silver, with the tokenized market exceeding $6 billion as of February 2026.

Introduction

Commodity-backed stablecoins are digital tokens that derive their value from physical assets such as gold, silver, oil, or carbon credits held in off-chain reserves by a custodian. These tokens differ from fiat-backed stablecoins, which hold dollar reserves to maintain a $1 peg. Commodity-backed tokens track the spot price of the underlying commodity, providing blockchain-based exposure to real-world markets.

Issuers deposit physical commodities with licensed custodians, such as LBMA-certified vaults for gold. Smart contracts mint tokens at a 1:1 ratio against verified reserves, with proof-of-reserve audits confirming the backing. Holders can redeem tokens for physical assets or fiat, subject to minimum thresholds.

The tokenized gold market surpassed $6 billion as of February 2026, with PAXG and XAUT dominating over 96% of the category. These tokens form part of the broader real-world asset (RWA) tokenization market, which exceeded $25 billion by early 2026.

What Are Commodity-Backed Stablecoins and How Do They Differ from Other Digital Assets?

A stablecoin is a digital token designed to hold a predictable value by linking it to an external reference asset. Most stablecoins use fiat currency or crypto assets as that reference. Commodity-backed stablecoins, however, derive their value from a physical asset — such as gold, silver, oil, or carbon credits — held in an off-chain reserve by a designated custodian.

The stablecoin market organises into four main types, each defined by what backs the token. Fiat-backed stablecoins (such as USDT and USDC) hold traditional currency reserves and target a fixed $1 peg — meaning the token's dollar value does not move. Crypto-collateralized stablecoins (such as DAI) lock digital assets in smart contracts, usually requiring overcollateralization to absorb price swings. Algorithmic stablecoins use no collateral at all; instead, they rely on code-based supply adjustments to target a peg, creating a higher-risk model. Commodity-backed stablecoins form the fourth type, where the collateral is a tangible physical asset stored outside the blockchain.

The key distinction for commodity-backed tokens lies in how their value behaves. Fiat-backed stablecoins maintain a fixed peg — the token is always worth approximately one dollar. Commodity-backed tokens track the spot price of the underlying commodity — that is, the current market price for immediate delivery — so their dollar value rises and falls with the commodity market. A gold-backed token, for example, gains value when gold prices rise and loses value when gold prices fall. This makes commodity-backed tokens less "stable" in the traditional dollar sense, but they offer direct exposure to real-world commodity markets through a blockchain-native instrument.

How Does the Minting, Custody, and Redemption Process Function for Commodity-Backed Tokens?

Every commodity-backed token follows a structured lifecycle that begins before a single token appears on a blockchain. A custodian — a licensed institution responsible for physically safeguarding the commodity — receives and stores the raw asset in a secured vault. For gold-backed tokens such as PAXG, Paxos Trust Company deposits physical gold with Brink's vaults in London, which hold LBMA (London Bullion Market Association) certification — the internationally recognised standard for gold bar quality and storage. The custodian then confirms the asset is in its possession before any token creation begins.

Once custody is confirmed, a smart contract — a self-executing program on the blockchain — mints new tokens at a 1:1 ratio against verified reserves. For PAXG, each token represents exactly one fine troy ounce of gold, the standard unit of mass used to weigh precious metals (approximately 31.1 grams). The smart contract can only create tokens when allocated gold — meaning gold assigned to specific bar numbers and serial identifiers — has been added to the vault. This on-chain rule prevents the issuer from minting tokens without corresponding physical backing.

Proof of reserve — the on-chain and third-party verification that token supply matches physical holdings — runs continuously for PAXG through monthly independent attestations by KPMG LLP, with public reports published on Paxos's transparency page. When a token holder wishes to exit, the redemption mechanism converts tokens back to physical metal or cash: PAXG requires a minimum of 430 tokens to receive a physical London Good Delivery gold bar, plus a $15,000 flat fee per redemption request as of March 2026. Tokens submitted for redemption are permanently burned — removed from circulation — so the on-chain supply always matches vault holdings.

What Types of Commodities Are Currently Tokenized and Which Projects Dominate the Market?

The tokenized commodity market currently concentrates almost entirely in precious metals, with gold accounting for the dominant share. As of February 2026, the total tokenized gold market surpassed $6 billion in market capitalisation, growing by more than $2 billion year-to-date. Beyond gold and silver, tokenized versions of energy commodities and carbon credit tokens — digital representations of verified emissions offset units — are emerging as separate sub-categories, though their combined market size remains a fraction of the metals segment.

Within tokenized gold, two issuers hold almost the entire market. PAXG (Paxos Gold), issued by New York-based Paxos Trust Company, carried a market capitalisation of approximately $2.55 billion as of 1 March 2026. XAUT (Tether Gold), issued by Tether, held a market capitalisation of approximately $2.9 billion as of February 2026. Together, PAXG and XAUT commanded roughly 96.7% of the total tokenized gold market as of February 2026. Both tokens peg to the same unit — one fine troy ounce of gold — but differ in custody location, regulatory status, and audit structure, which are covered in later sections.

KAU (Kinesis Gold) and KAG (Kinesis Silver), issued by Kinesis Money, represent the silver segment and a smaller gold alternative. KAU held a market capitalisation of approximately $350 million as of 28 March 2026, with each token representing one gram of 0.9999-fineness allocated gold. KAG, a silver-backed token where each unit represents one gram of physical silver, carried a market capitalisation of approximately $275 million as of late March 2026. A true oil-backed token — a token backed 1:1 by physically held crude oil — does not yet exist at meaningful scale; current energy tokenization projects typically issue security tokens representing equity stakes in oil-producing entities, a distinct legal structure.

What Are the Main Benefits of Holding Commodity-Backed Stablecoins for Crypto Investors?

Commodity-backed stablecoins offer four distinct advantages over both physical commodities and other digital asset classes. First, they provide inflation hedge exposure — protection against the declining purchasing power of fiat currencies — by tracking an asset that has historically gained value during inflationary periods. Second, they remove the logistical barriers of physical ownership: no vaulting costs, no delivery contracts, and no minimum bar sizes. Third, blockchain-based tokens trade 24 hours a day, seven days a week, unlike traditional commodity exchanges that operate within set market hours. Fourth, their low correlation to Bitcoin and equities means they can act as a portfolio diversification tool — spreading risk across assets that do not move in the same direction at the same time.

Key benefits at a glance:

• Inflation hedge — gold-backed tokens track gold's long-run tendency to preserve purchasing power during fiat debasement periods
• Fractional access — PAXG is divisible to 18 decimal places, with a minimum purchase of 0.03 PAXG on the Paxos platform, removing the need to buy a whole troy ounce
• 24/7 blockchain liquidity — tokens trade on crypto exchanges around the clock, unlike the London gold fix or CME futures markets which have set trading hours
• Portfolio diversification — gold's rolling 5-year correlation with inflation is 0.16, and its price movements differ substantially from Bitcoin's, providing a volatility buffer in mixed portfolios

How Do Commodity-Backed Tokens Function as an Inflation Hedge in Crypto Portfolios?

Gold's relationship with inflation operates primarily through real interest rates — that is, nominal interest rates minus the inflation rate. When real interest rates turn negative (inflation exceeds the yield on bonds), holding non-yielding assets such as gold becomes comparatively attractive, driving demand and price. Economists including Robert Barsky and Lawrence Summers documented this inverse relationship between real interest rates and gold prices using data from 1973 to 1984, and the pattern has recurred in subsequent cycles.

Gold delivered a 27.87% price gain in 2024, reaching record highs above $3,499 per ounce in 2025, as core inflation remained above 2.9% and central bank demand accelerated. The World Gold Council reported that gold rose 26% in US dollar terms in just the first half of 2025 alone — its strongest first-half performance in decades. Gold-backed tokens such as PAXG and XAUT captured this price movement in full, since each token tracks the spot price of one troy ounce of allocated gold with no structural drag from management fees.

How Do Commodity-Backed Stablecoins Compare to Fiat-Backed and Algorithmic Stablecoin Types?

Placing commodity-backed tokens alongside other stablecoin types reveals a clear trade-off between peg stability — how closely a token holds a fixed price — and the type of real-world exposure the token delivers. Fiat-backed stablecoins such as USDT and USDC maintain a 1:1 dollar peg by holding cash or short-term US Treasuries as reserves, with each token redeemable for one US dollar. Their dollar value does not fluctuate, which makes them effective as a stable medium of exchange but provides no protection against the declining purchasing power of the dollar itself.

Crypto-collateralized stablecoins such as DAI take a different approach: users lock cryptocurrency into a smart contract at a minimum 150% collateralisation ratio to mint tokens, creating a buffer against the collateral's price volatility. The overcollateralisation protects the peg but ties up capital inefficiently and introduces liquidation risk if collateral values drop sharply. Algorithmic stablecoins carry the highest risk profile: they hold no collateral and rely entirely on code-based supply-and-demand adjustments. The May 2022 collapse of TerraUSD (UST) demonstrated this vulnerability — UST lost its $1 peg and fell to approximately $0.09, erasing an estimated $60 billion in value.

Commodity-backed tokens sit outside this dollar-peg framework entirely. Their value tracks the spot price of the underlying physical asset, which means the token's dollar value moves up and down as the commodity market moves. This makes them less suitable as a stable medium of exchange but gives holders direct exposure to commodities — and the counterparty risk (the risk that the token's value depends on a third party fulfilling its obligations) differs in nature: it rests on custodian solvency and audit integrity rather than on the stability of an algorithm or a fiat reserve.

What Risks and Challenges Should Investors Consider When Holding Commodity-Backed Tokens?

Commodity-backed tokens carry four distinct risk categories that operate independently of the blockchain itself. The first is counterparty risk — the exposure a token holder has to the financial health and operational integrity of the issuer. A token's value ultimately depends on the issuer maintaining adequate physical reserves and honouring redemption obligations; if the issuer becomes insolvent or misrepresents its holdings, the token's backing disappears. Paxos Trust Company holds a Limited Purpose Trust Charter granted by the New York Department of Financial Services (NYDFS) in 2015, placing it under state-level capital, custody, and compliance requirements. Tether, by contrast, operates as a commercial entity without equivalent state trust charter oversight for its XAUT product, requiring users to rely on voluntary issuer disclosures.

The second risk is commodity price volatility. Gold-backed tokens are not dollar-stable instruments; the spot price of gold fell approximately 4% in a single trading week during early 2022, and rose more than 27% across full-year 2024. Holders seeking a fixed-value store of account should use fiat-backed stablecoins instead. The third risk involves redemption restrictions that make physical delivery inaccessible to most retail holders. PAXG requires a minimum of 430 tokens to receive a physical London Good Delivery bar — equivalent to approximately $1.18 million at gold prices as of March 2026 — plus a $15,000 flat redemption fee. XAUT allows physical gold delivery only in Switzerland, with logistics, insurance, and identity verification requirements that add further cost and friction.

The fourth risk is smart contract risk: on-chain vulnerabilities in the token's code exist independently of the physical reserve. A smart contract exploit could allow unauthorised minting or token theft without any corresponding change to the vault holdings, leaving honest holders with worthless tokens even if the gold remains intact. This category of risk applies to all blockchain-based tokens and requires separate evaluation from the custodian and reserve quality assessment.

How Does Custodian Risk Differ Between Regulated and Unregulated Token Issuers?

Regulated issuers and unregulated issuers create substantially different risk profiles for token holders, even when both claim full physical backing. Paxos, as a NYDFS-chartered trust company, must maintain segregated customer assets, submit to periodic examinations by state regulators, and publish monthly third-party reserve attestations — currently conducted by KPMG LLP under AICPA standards. This structure means a regulator independently monitors reserve adequacy and can intervene if Paxos fails to meet its obligations.

Tether's XAUT operates without equivalent mandatory regulatory oversight: the company publishes quarterly attestations rather than monthly audits, and these are issued by BF Borgers — a firm that has faced SEC scrutiny — without the same standardised framework applied to Paxos. Investors evaluating unregulated issuers should verify: the frequency and scope of reserve audits, the auditor's independence and qualifications, whether the physical gold is held in allocated (named-bar) or unallocated (pooled) form, and the jurisdiction of the vault. Allocated gold — where each token maps to specific bar serial numbers — provides stronger legal protection in insolvency than unallocated pooled holdings.

What Regulatory Frameworks Currently Govern Commodity-Backed Stablecoins Across Major Jurisdictions?

Commodity-backed stablecoins occupy an ambiguous position in most regulatory frameworks because they do not fit neatly into either the "payment stablecoin" or the "security" category. In the United States, Congress passed the GENIUS Act (Guiding and Establishing National Innovation for US Stablecoins Act) in July 2025, establishing the first federal regulatory framework for digital assets. The Act defines a payment stablecoin as a token backed 1:1 by US dollars or short-term Treasuries — a definition that explicitly excludes commodity-backed tokens. As a consequence, PAXG and XAUT fall outside GENIUS Act protections and remain subject to existing state-level trust law or, potentially, CFTC jurisdiction under the Commodity Exchange Act (CEA) — the US statute governing derivatives and commodity trading.

On 17 March 2026, the SEC and CFTC jointly issued historic interpretive guidance classifying 16 major cryptocurrencies as digital commodities under the CEA, and confirming that most crypto assets are not securities. The guidance does not specifically name commodity-backed tokens such as PAXG or XAUT, leaving their classification — security, commodity, or hybrid instrument — without a definitive federal answer as of March 2026. Paxos Trust Company applied to the Office of the Comptroller of the Currency (OCC) for a national trust bank charter in early 2026, which would bring PAXG under federal oversight for the first time.

In the European Union, MiCA (Markets in Crypto-Assets Regulation), fully effective from December 2024, classifies commodity-backed tokens as Asset-Referenced Tokens (ARTs) — defined as crypto-assets that maintain stable value by referencing one or more assets including commodities. ART issuers must obtain authorisation from their national competent authority, maintain a fully backed reserve of high-quality liquid assets, publish a regulatory white paper meeting strict disclosure standards, and honour redemption rights for all holders. The European Banking Authority (EBA) supervises significant ART issuers directly, with national regulators overseeing smaller ones.

What Role Do Commodity-Backed Stablecoins Play in the Broader RWA Tokenization Market?

Real-world asset (RWA) tokenization refers to the process of representing ownership of a physical or traditional financial asset as a digital token on a blockchain. The total on-chain RWA market, excluding stablecoins, surpassed $25 billion by early 2026 — nearly quadrupling in one year — with six asset categories individually exceeding $1 billion each, including treasuries, commodities, private credit, alternative funds, corporate bonds, and non-US government debt. Commodity-backed stablecoins, with the tokenized gold market alone exceeding $6 billion as of February 2026, represent the largest single commodity category within this broader ecosystem.

Within the RWA landscape, commodity-backed tokens sit alongside but remain distinct from tokenized Treasuries, which surpassed $7.4 billion at mid-2025. Institutional momentum reinforces the category: BlackRock and JPMorgan entered RWA tokenization infrastructure in 2025 and 2026 respectively, with commodities among the targeted asset classes. Market analysts project the total RWA tokenization market to reach between $16 trillion and $18.9 trillion by 2030, driven by institutional adoption, fractional access to illiquid assets, and regulatory clarity. Commodity tokenization benefits from the same structural drivers: global commodity markets remain fragmented, settlement-heavy, and inaccessible to retail participants without significant capital.

Commodity-backed tokens solve three structural inefficiencies in traditional commodity markets. First, physical commodity markets operate within fixed exchange hours and require settlement periods of one to two business days; blockchain tokens settle in minutes, 24 hours a day. Second, minimum contract sizes on futures exchanges — a standard COMEX gold futures contract covers 100 troy ounces — exclude small investors; tokenized gold units start at fractions of a gram. Third, global investors in emerging markets lack access to regulated commodity exchanges entirely; a blockchain wallet and an internet connection suffice to hold a gold-backed token.

How Are Oil and Carbon Credit Tokens Being Developed Within the RWA Ecosystem?

Current "oil-backed tokens" are not commodity-backed stablecoins in the strict sense. Projects such as Tokenized Energy structure their digital assets as security tokens — tokens that represent an equity stake in a special purpose vehicle (SPV) or limited partnership that owns oil and gas assets — rather than tokens backed 1:1 by barrels of physically held crude oil. This is a legally critical distinction: security token holders own a share of a company, while commodity-backed stablecoin holders have a direct claim on a specific physical asset in custody. A security token's value depends on the producing entity's operational performance and legal structure; a commodity-backed token's value depends solely on the spot price of the underlying commodity and the custodian's reserve integrity.

Carbon credit tokenization operates under a different model again. Toucan Protocol converted retired Verified Carbon Units (VCUs) from the Verra registry into on-chain Base Carbon Tonne (BCT) tokens between 2021 and 2022, before Verra prohibited further unauthorised tokenization of its credits. Unlike gold-backed tokens, carbon credit tokens represent retired — already used — environmental credits rather than a fungible physical commodity held in ongoing custody, meaning their economic mechanics, liquidity profile, and redemption rights differ fundamentally from precious-metals tokenization.
