Stablecoin Track Heats Up: The GENIUS Bill Faces Obstacles and SoFiUSD Joins Mastercard in a Double Signal

By the beginning of March 2026, the stablecoin sector has simultaneously seen two seemingly opposing yet fundamentally interconnected strong signals. On one hand, in Washington’s political arena, Trump publicly criticizes the banking industry for attempting to weaken the GENIUS Act; on the other hand, in the commercial application layer, payment giant Mastercard announces the integration of bank-issued stablecoin SoFiUSD into its global settlement network. This “one阻一进” dual event precisely outlines the core contradiction in the current stablecoin ecosystem: amid intense regulatory battles, the adoption path of stablecoins as the next-generation payment infrastructure is becoming increasingly clear.

Event Overview: Regulatory Battles and Commercial Breakthroughs

This week, two landmark events occurred in the stablecoin field.

The first focuses on the U.S. political center. Trump explicitly stated on Truth Social that large banks are attempting to weaken the GENIUS Act and hinder related crypto policies. He warned that if legislation stalls, opportunities for the crypto industry might flow to countries like China, and called for banks to cooperate with the crypto sector. This statement publicly exposes the legislative battle over the rights to stablecoin yields.

The second event takes place in the global payments sector. SoFi Technologies announced a deepening partnership with Mastercard, planning to use its compliant stablecoin SoFiUSD as a settlement currency within Mastercard’s global payment network. This means that in the future, card issuers and acquirers will be able to settle transactions in real-time using bank-issued digital dollars.

Regulatory Background and Timeline: The Battle Over Yield Rights Heats Up

To understand the strength of Trump’s recent statement, one must review the legislative process of the GENIUS Act. Enacted in July 2025, it established a basic framework for “payment stablecoins” and explicitly prohibited issuers from paying “interest or yields” to holders.

However, the market quickly identified legal loopholes: while issuers cannot pay interest, behaviors like reward programs or affiliated platforms distributing yields to users are not explicitly banned. This raised alarms among banks, who believe that if consumers can hold a stablecoin that is as safe as the dollar but also generates yields, it would threaten traditional deposit bases and pose systemic risks of capital outflows.

In response, the U.S. Office of the Comptroller of the Currency (OCC) recently proposed new implementation rules to close this loophole. The core measure is establishing a “rebuttable presumption”: if a stablecoin issuer and related parties agree to pay yields to token holders, such behavior will be directly deemed as prohibited “interest,” regardless of the number of intermediaries involved.

Trump’s intervention comes against this backdrop. He accused banks of leveraging their influence in Congress to tighten rules further, even using another key legislation—the Clarity Act—as a bargaining chip. House Financial Services Committee Chair French Hill suggested that if the Senate cannot agree on amendments to the GENIUS Act, they should consider adopting the language of the House-passed Clarity Act to break the deadlock.

Data and Structural Analysis: On-Chain USD Expanding Against the Trend

Behind the regulatory disputes is the ongoing expansion of stablecoins as a “shadow dollar” system. According to DefiLlama data, as of early March 2026, the total market cap of stablecoins has surpassed $311.28 billion. The Gate Research Institute notes that this figure has hit a new high after cyclical retracements, indicating that the market has not abandoned dollar-denominated tools despite concerns over the long-term outlook for the dollar.

In terms of usage, the total on-chain stablecoin transaction volume for 2025 was approximately $33 trillion, a 70% increase year-over-year. This scale has already had a tangible impact on traditional finance. For example, in 2024, stablecoin issuers purchased about $40 billion in short-term U.S. government bonds, comparable to the largest government money market funds, becoming a structural influence on short-term U.S. interest rates.

Mastercard’s decision to integrate SoFiUSD is a response to this structural shift. Traditional cross-border payments rely on correspondent banking networks, with settlement times of 1-3 business days. Blockchain-based stablecoins, with 24/7 near-instant settlement, can significantly improve capital efficiency.

Public Opinion and Perspectives

Regarding these dual signals, the market has seen a clear debate between bullish and cautious viewpoints.

Supporters see this as a key step toward real-world asset applications for stablecoins. Industry analysts point out that Mastercard’s partnership with SoFi validates the feasibility of the “compliant stablecoin + traditional payment network” model. Mastercard’s global digital commerce head stated that the move aims to connect trusted digital currencies with the reliability expected by consumers and institutions. For crypto-native communities, this is viewed as a substantive breakthrough from “crypto bubble” to mainstream financial infrastructure.

Cautious and controversial opinions mainly focus on regulation. Banking groups insist that allowing stablecoins to indirectly pay yields would undermine financial stability. Some observers worry that, although SoFiUSD is issued by a bank, its underlying technology is still based on public blockchains, and smart contract risks remain. Additionally, OCC’s new regulation proposals suggest tightening oversight, and any behavior involving “reward” mechanisms to distribute yields could be reclassified as illegal.

Authenticity of the Narrative

In the crypto industry, “adoption by traditional finance” often involves exaggerated concepts. Regarding the partnership between SoFiUSD and Mastercard, we must strictly distinguish between facts, opinions, and speculation.

• Facts: The two parties have signed a cooperation agreement; SoFi plans to use SoFiUSD for settlement of its credit and debit card transactions on Mastercard’s network; its platform Galileo will provide settlement options for issuing banks; SoFiUSD is integrated into Mastercard’s multi-token network.
• Opinions: Statements by senior executives about “changing global capital flows,” “faster, cheaper, safer transactions” reflect strategic expectations of long-term potential.
• Speculation: The partnership is still in the “exploration” and “planning” stages; specific timelines, the number of issuing banks adopting SoFiUSD, and transaction volumes are not yet clear. Interpreting this as “Mastercard fully accepting stablecoin settlement” is an overreach; a more accurate description is that Mastercard has added a bank-issued compliant stablecoin as an optional settlement tool.

Industry Impact Analysis

These events will have the following structural impacts on the stablecoin sector and the broader crypto industry:

• Accelerating Stablecoin Segmentation: Compliance is becoming a core variable in stablecoin competition. SoFiUSD, issued by an OCC-regulated bank and integrated into mainstream payment networks, differentiates itself from giants like USDT and USDC. For highly regulated institutional users, bank-backed stablecoins will be more attractive.
• Promoting B2B Payment Infrastructure Upgrades: Compared to the competitive C-end payments, B2B cross-border payments have vast market potential and more acute pain points. SoFiUSD’s settlement on Mastercard’s network could accelerate stablecoin adoption in enterprise fund flows and push traditional clearing institutions to upgrade systems.
• Reshaping Business Models: OCC’s strict definition of “yield” is closing off avenues for stablecoin issuers to indirectly share yields via third-party platforms. This will force the industry to rethink business models. As Bankless analysis suggests, if earning yields from digital cash is blocked, yields will shift into legitimate structures linked to government bonds, such as tokenized money market funds.

Evolution Scenarios for the Next 6-12 Months

Based on current regulatory and market dynamics, the stablecoin sector may evolve along these scenarios:

Scenario 1 (Baseline): Legislative compromise and compliance expansion

Both houses reach a consensus on amendments to the GENIUS Act, explicitly banning direct or indirect payment of “yields” by stablecoins but allowing bank-issued compliant stablecoins to circulate freely within payment networks. Under this scenario, bank-backed stablecoins like SoFiUSD will develop rapidly, with their primary function limited to “payment” rather than “savings.”

Scenario 2 (Regulatory tightening): Strict enforcement and market cleansing

If OCC’s strict rules are implemented and the Clarity Act faces obstacles in the Senate, the regulatory environment will tighten significantly. Many third-party stablecoins and DeFi protocols relying on “reward” mechanisms will face compliance pressures, possibly leading to market concentration among top compliant stablecoins and the exit of some products.

Scenario 3 (Innovation breakthrough): Emergence of new packaging layers

Regulatory restrictions on stablecoin yields may spur innovation in “wrapping” products. The market could see a new class of “digital savings” tools, existing as tokenized money market funds with clear boundaries from payment stablecoins. Users could switch flexibly between these layers, satisfying both payment and yield needs.

Conclusion

SoFiUSD’s partnership with Mastercard exemplifies the technological potential of stablecoins as efficient payment tools; meanwhile, the obstacles faced by the GENIUS Act and Trump’s intervention reveal that realizing this potential requires navigating a complex regulatory maze. These two signals point to a conclusion: stablecoins are evolving from fringe crypto assets into a key variable shaping the future of the global monetary system. For industry participants, whether betting on compliance adoption or engaging in regulatory battles, it’s crucial to recognize that the future of stablecoins will be written jointly by Washington’s legislation and Silicon Valley’s code.
