Another stablecoin. Another Islamic finance analysis. And by now, Muslim investors who have followed our analysis series may already sense where this is heading.
Global Dollar joins USDT, USDC, DAI, PYUSD, FDUSD, and others as a stablecoin seeking to provide dollar-denominated stability within blockchain ecosystems. Like its predecessors in this analysis series, USDG offers genuine practical utility. And like its predecessors, the financial structure underneath that utility is what determines its compliance status.
We ran USDG through the full CoinStudy Halal Crypto Standard (HCS) methodology. Here is the complete picture, including an important broader principle that every Muslim investor should understand about stablecoins.
USDG fails the CoinStudy HCS Sharia red-line screening. Its reserve backing structure relies on interest-bearing financial instruments, treasury-related assets, and conventional banking infrastructure, triggering three automatic red-line failures and an immediate Haram classification.
Global Dollar (USDG) is a fiat-backed stablecoin designed to maintain a stable value of one US Dollar. It is built for payments, transfers, trading, liquidity management, and blockchain-based financial transactions.
Like other dollar-pegged stablecoins, USDG aims to give users the price stability of the US dollar within blockchain ecosystems, avoiding the volatility of assets like Bitcoin or Ethereum while still enabling fast and accessible digital transfers.
The use cases are practical and legitimate, including digital payments, remittances, trading, liquidity management, stable value transfers, and blockchain settlements. There is nothing inherently problematic about wanting a stable digital asset for these purposes.
The problem, as always with fiat-backed stablecoins, is how that stability is achieved and maintained.
USDG maintains its dollar peg through reserve assets held by custodians and financial institutions.
Those reserves include cash deposits, Treasury instruments, money market assets, cash equivalents, and reserve management accounts. For every USDG token in circulation, equivalent value is held in these reserve assets, ensuring that holders can always redeem their tokens for dollars.
This reserve model is standard practice for fiat-backed stablecoins. It is how USDT, USDC, PYUSD, and FDUSD work too. And it is the source of the same fundamental problem across all of them.
Treasury instruments including US Treasury bills, notes, and bonds are interest-bearing financial instruments. They generate returns through interest payments from the US government. Money market assets operate similarly. Cash deposits in conventional banking institutions earn interest. The entire reserve infrastructure that makes USDG stable and redeemable generates income through interest-based financial mechanisms.
This is one of the most important principles in the CoinStudy HCS methodology and it is worth stating clearly for Muslim investors who may not have considered it.
Placing an asset on a blockchain does not change the nature of that asset. Tokenizing a Treasury bill does not make it halal. Representing cash deposits on Ethereum does not remove their interest-bearing characteristics. The blockchain is a distribution and transfer mechanism. It does not transform the financial nature of what is underneath.
USDG is a blockchain token. But what backs that token, which is Treasury securities, bank deposits, and money market instruments, retains all of its original financial characteristics. The interest those assets generate is still interest. The Riba concern is still Riba. The blockchain wrapper changes the format, not the substance.
This principle applies not just to USDG but to every fiat-backed stablecoin. Any stablecoin that maintains its peg through reserves held in conventional interest-bearing financial instruments carries this fundamental compliance problem regardless of which blockchain it operates on.
The reserve assets supporting USDG generate returns through interest-bearing bank deposits, Treasury securities, money market instruments, and fixed-income financial products.
This is Riba. The interest income generated from these reserves is how the entities behind USDG sustain the financial infrastructure needed to maintain the dollar peg. The stability that makes USDG useful is funded by and dependent on interest-based financial mechanisms.
Under the CoinStudy HCS methodology, this creates a decisive Sharia compliance failure that triggers the primary red-line violation.
USDG is specifically designed to reduce volatility. Price stability is maintained effectively. Reserve disclosures and redemption mechanisms are in place.
From a pure uncertainty perspective, USDG performs better than most cryptocurrencies. But transparency about a prohibited structure does not make that structure permissible. The reserve management, custodial oversight, and centralized financial controls involved in maintaining USDG's peg add some additional complexity and uncertainty, but these are secondary concerns. The Riba failure is the decisive issue.
USDG was not created for gambling or speculation. Its intended functions of payments, settlements, remittances, and liquidity management are legitimate in isolation.
However stablecoins are widely used throughout leveraged trading platforms, DeFi lending systems, yield-generating protocols, and speculative crypto markets. USDG's integration with these environments increases ecosystem-level exposure to speculative financial behavior. This is a contextual concern rather than a core structural one. The Riba failure determines the outcome.
Ecosystem Riba Exposure — ❌ Failed. USDG reserves include US Treasury bills, bank deposits, and money market instruments that generate interest income funding the reserve management infrastructure maintaining the dollar peg.
Guaranteed Interest — ❌ Failed. Treasury bills, money market instruments, and bank deposits in USDG's reserves generate predetermined guaranteed interest returns constituting guaranteed interest income at the institutional level.
Synthetic Interest Products — ❌ Failed. USDG functions as a synthetic dollar token representing a claim on an interest-bearing reserve pool, functioning economically as a synthetic interest-bearing instrument.
Gambling and Betting — ✅ Passed.
Haram Industry — ✅ Passed.
Three red lines failed. Under the CoinStudy HCS framework, any single red-line failure results in an automatic Haram classification. Three failures makes this result definitive and unambiguous.
Layer 2 scoring is skipped entirely. As per the CoinStudy methodology, projects that fail Layer 1 are not eligible for further scoring.
Overall Result: Haram — Red Line Violations
By this point in our analysis series, Muslim investors deserve a direct and honest conversation about what the consistent pattern across stablecoin assessments means.
USDT is Haram due to interest-linked reserves. USDC is Haram due to interest-bearing reserves managed by Circle. DAI is Haram due to its debt-based creation mechanism with stability fees functioning as interest charges. PYUSD is Haram due to US Treasury bills and cash-equivalent reserves. FDUSD is Haram due to the same Treasury bill-backed structure with additional Binance ecosystem dependency. USDG is Haram due to Treasury instruments, bank deposits, and money market assets.
Six stablecoins. Six Haram classifications. Different issuers, different platforms, different levels of decentralization. The same fundamental problem.
This is not a coincidence and it is not a quirk of the CoinStudy methodology. It reflects a genuine structural reality. The most common and proven methods of creating a stable digital dollar all involve interest-based financial mechanisms in some form.
Fiat-backed stablecoins hold interest-bearing reserves. Crypto-backed stablecoins like DAI use debt mechanisms with interest-like stability fees. Algorithmic stablecoins have historically been unstable and potentially dangerous. The halal stablecoin problem is real, significant, and not yet solved in the mainstream market.
The consistent Haram classification of major stablecoins creates a genuine and practical challenge that deserves acknowledgment.
Muslim investors legitimately need stable digital assets for various purposes including holding value without volatility, making payments in the crypto ecosystem, participating in halal blockchain applications, or simply moving funds efficiently across networks.
The answer is not to use Haram stablecoins and rationalize it as necessary. The answer is to understand the problem clearly, seek genuinely Sharia-compliant alternatives where they exist, and advocate for the development of halal stablecoin solutions that address the structural issues identified in this analysis series.
Potential approaches that could yield genuinely halal stablecoins include gold-backed tokens where reserves consist of physical gold rather than interest-bearing instruments, commodity-backed structures using real assets that do not generate interest income, and equity-backed models where reserves consist of Sharia-compliant asset portfolios. CoinStudy is committed to publishing full HCS analysis reports on alternative stablecoin models to help Muslim investors navigate this space as the market develops.
One aspect of USDG that adds to the compliance concern is its dependence on centralized reserve management through custodians, banking partners, reserve operators, and financial institutions.
These entities all operate within conventional interest-based financial systems. The chain of custody for USDG's reserves runs through organizations whose standard operations involve interest-based banking relationships.
This centralization means Muslim investors have no direct visibility into or control over whether the specific reserves backing their USDG are managed in a Sharia-compliant way. The entire reserve management infrastructure operates according to conventional financial principles, generating interest as a matter of standard practice.
Before using any stablecoin regardless of its brand recognition or platform, ask yourself honestly.
How exactly are the reserves managed and by whom? Do the reserve assets generate interest income as a matter of standard operation? Is there any mechanism for the reserve structure to be genuinely Sharia-compliant? Does the project depend on conventional banking systems and Treasury instruments for its stability? Are there genuinely halal alternatives that serve my practical need for a stable digital asset?
These questions apply to every stablecoin including USDG, USDT, USDC, PYUSD, and any future stablecoin that enters the market. The issuer's name and the blockchain it operates on are less important than the financial structure underneath.
Global Dollar (USDG) is classified as Haram / Non-Compliant under the CoinStudy Halal Crypto Standard.
Its reserve backing structure relies on interest-bearing financial instruments, Treasury-related assets, centralized reserve management through conventional banking infrastructure, and money market instruments that generate interest income. These features trigger three red-line violations under the CoinStudy HCS framework.
The practical utility USDG provides including payments, remittances, digital commerce, settlements, and stable value transfers is real and acknowledged. But utility does not override compliance. The financial structure that creates and maintains USDG's stability is incompatible with Islamic finance principles.
For Muslim investors, USDG joins a growing list of major stablecoins that cannot be recommended under Islamic finance principles. The search for genuinely halal stable value in the digital asset space remains one of the most important and unresolved challenges in Islamic crypto finance.
CoinStudy's HCS methodology classifies USDG as Haram based on the structural Riba concerns in its reserve backing. The Treasury bills, bank deposits, and money market instruments that maintain its dollar peg are interest-bearing financial instruments. This structural Riba triggers our red-line screening.
However CoinStudy's Shariah Board acknowledges a significant scholarly disagreement on this question that Muslim investors deserve to know about.
Some contemporary Islamic finance scholars hold that using dollar-pegged stablecoins purely as a medium of exchange is permissible. Their reasoning is rooted in a well-established Islamic jurisprudence principle. The sin of a prohibited act belongs to the actor who performs it, not to every person in the chain who subsequently uses the resulting product. Under this view, the issuer commits the prohibited act by holding Riba-generating reserves. That sin belongs to the issuer. The Muslim who uses USDG for payments or trading is not holding Treasury bills, not earning interest, and not committing the prohibited act themselves.
This position is further supported by the fact that ordinary users never directly interact with the underlying reserve instruments at all, receiving only dollar value upon redemption with zero contact with the interest-bearing assets themselves.
CoinStudy's HCS classification remains Haram because our methodology evaluates structural compliance. The reserve structure triggers our red lines regardless of user intent or usage purpose.
But Muslim investors should understand that this is a genuine area of scholarly disagreement, not a settled question with unanimous consensus. If you use USDG purely as a medium of exchange for trading or payments and do not earn or seek yield from it, you should consult a qualified Islamic scholar for personal guidance on your specific usage.
The prohibition of the structure and the permissibility of the usage are two different questions that can have different answers. CoinStudy answers the structural question. The usage question requires personal scholarly guidance.

Authoritative ruling from the Chairman of the CoinStudy Sharia Board.
"Scholars have differing opinions regarding USDT and other fiat-backed stablecoins. Some scholars consider it impermissible and some consider it permissible. According to our research, its use is permissible. Its backend structure and currency leveling method is not interest in totality, however caution is necessary due to the presence of interest-based transactions within it. There is also an element of Gharar in that it is not certain that there is a dollar behind every unit. Despite this, its use as a digital currency is correct. If it is used in halal means the profit will be halal, and if it is used in haram dealings it will be haram."
This ruling applies to USDT and to other structurally similar fiat-backed stablecoins. CoinStudy's HCS structural classification remains as noted above, reflecting the interest-adjacent backend and Gharar elements the chairman himself identified. However the chairman's ruling confirms that using USDT or other fiat-backed stablecoins purely as a digital medium of exchange in halal transactions is permissible under his scholarly assessment. This is entirely consistent with the Scholarly Disagreement section published above.
